But then, no other automaker has an on-the-road system as experimental as Autopilot, or perhaps the need to make midcourse corrections to such a fundamental feature of its vehicles.
|
|
If an enemy fires a warhead at us, our wars in the Middle East cannot defend us against it mid-course in space, the way Ground-Based Midcourse Defense (GMD) can.

As Iran continues testing ballistic missiles designed to carry nuclear weapons ("Iran test-fires new round of ballistic missiles," March 6900), the need to fully fund our ground-based midcourse defense (GMD) system has never been clearer.
|
|
Older readers may remember that NASA only needed one midcourse correction on its way to the moon, but the Fed seems to need repeated corrections if the consensus view of a December rate cut also comes through.
|
|
This part of the missile's trajectory is called "midcourse," and it is the most difficult time for an interception, because a fast-moving warhead can also release decoy balloons that are hard to distinguish from the real thing.
|
|
The idea which was mocked at the time as science fiction akin to "Star Wars," has developed into several anti-ballistic missile defense systems, including the Terminal High Altitude Area Defense (THAAD) and Ground-Based Midcourse Defense (GMD).

|
|
The U.S. Missile Defense Agency - charged with developing, testing and fielding a ballistic missile defense system - will delay the expansion of the Ground-based Midcourse Defense (GMD) system by two years because of a delay in the redesign of the Raytheon Co-made "kill vehicle" the system uses.
|
|
The Aegis Ashore radar choice was between Raytheon Co's Spy-6 radar, designed to upgrade the U.S. Navy's fleet of Aegis warships, and a version of Lockheed Martin Corp's Long Range Discrimination Radar, which will be deployed in the Ground-Based Midcourse Defense anti-ballistic missile system in Alaska around 2020.
|
|
The THAAD system is designed to destroy missiles during the terminal phase of their trajectories, when they are coming back down; it can do nothing against missiles during their boost or midcourse phase, so Chinese missiles aimed at America would have nothing to fear from a THAAD battery in South Korea.
|
|
"The question is whether our system is set up today in a way to do little midcourse corrections as time goes on, or is it not," said Dana Trier, who left the Treasury Department last month after serving as deputy assistant secretary for tax policy during the drafting of the bill.
|
|
The ground-based midcourse missile defense system, which has deployed 30 interceptors in Alaska and California, has been tested under highly scripted conditions only nine times since being deployed in 2004, and failed to destroy its target two-thirds of the time, the Union of Concerned Scientists said in a report.
|
|
On May 30 the U.S. Missile Defense Agency (MDA) held its 10th successful test, in 18 attempts, of the Ground-based Midcourse Defense (GMD) system, a network of radars, anti-ballistic missiles and other equipment designed to protect the United States from intercontinental ballistic missiles (ICBMs) launched from North Korea or Iran.

Mobile elements can defend against medium and short ranged missiles in midcourse.
|
|
Ballistic missiles can be intercepted in three regions of their trajectory: boost phase, midcourse phase, or terminal phase.
|
|
The first stage also had two fixed air vanes for stability during first stage powered flight. The midcourse phase of the trajectory was initiated at RV separation and continued until the terminal phase began. At the beginning of the midcourse phase, the RV was pitched down to orient it for reentry and to reduce its radar cross-section. The midcourse attitude was then controlled by the RV vane control system during atmospheric exit and reentry, and by a reaction control system during exoatmospheric flight.

The mid-infrared image of the Moon was taken during a September 1996 lunar eclipse by the SPIRIT-III instrument aboard the orbiting Midcourse Space Experiment (MSX) satellite. During its totality, the Midcourse Space Experiment (MSX) satellite's SPIRIT-III instrument took the image of the Moon in mid-infrared. At these wavelengths, MSX was able to characterize the thermal (heat) distribution of the lunar surface during the eclipse. The brightest regions are the warmest, and the darkest areas are the coolest.

Ground controllers sent commands to unfurl the high-gain antenna and align the probe for the midcourse burn, but during this time more electrical shorts apparently occurred because there was a momentary dropout from the telemetry transmitter. The midcourse engine was fired, but Ranger 5 exhausted its batteries halfway through the burn. The radio transponder and telemetry signals ceased, followed by uncontrolled tumbling of the probe. Ranger 5 passed 450 miles from the lunar surface en route to a permanent orbit around the Sun.

Today's observatory was initiated by the Advanced Research Projects Agency (ARPA) in 1961 as the ARPA Midcourse Optical Station (AMOS). It was first proposed by R. Zirkind of ARPA's staff for imaging ballistic missile payloads and decoys during their midcourse phase, and other space objects including satellites, in the infrared spectrum, as well as for performing astronomical research. Its location on Mount Haleakala was nearly ideal for its altitude high above much obscuration by water vapor, for its midcourse location between the missile launch site at Vandenberg Air Force Base and its main reentry location at Kwajalein Atoll, and for its low-latitude location which was advantageous for observing satellites. The AMOS effort formally began with an amendment to an existing ARPA order with the University of Michigan's Institute for Science and Technology, which was to design, construct, and operate the facility.

The US missile defense complex in Poland was part of the Ballistic Missile Defense European Capability of the US, to be placed in Redzikowo, Słupsk, Poland, forming a Ground-Based Midcourse Defense system in conjunction with a US narrow-beam midcourse tracking and discrimination radar system in the Brdy, Czech Republic. The plan was cancelled in 2009. Polish society was divided on the issue. According to a poll by SMG/KRC released by TVP 50 per cent of respondents rejected the deployment of the shield on Polish soil, while 36 per cent supported it.
|
|
The perceived advantage of STSS is that its satellites, by operating at a lower altitude and by using long- and short-wave infrared sensors, will be able to acquire and track missiles in midcourse and during the boost phase.
|

A Ground-Based Interceptor loaded into a silo at Fort Greely, Alaska in July 2004. Ground-Based Midcourse Defense (GMD) is the United States' anti- ballistic missile system for intercepting incoming warheads in space, during the midcourse phase of ballistic trajectory flight. It is a major component of the American missile defense strategy to counter ballistic missiles, including intercontinental ballistic missiles (ICBMs) carrying nuclear, chemical, biological or conventional warheads. The system is deployed in military bases in the states of Alaska and California; in 2018 comprising 44 interceptors and spanning 15 time zones with sensors on land, at sea, and in orbit.
|
|
The midcourse phase represents the majority of the time of flight of a ballistic missile, from minutes to the better part of an hour depending on the range of the missile. During this phase the payload follows a ballistic trajectory, with warheads, decoys and radar reflectors mixed together in an extended formation known as the target cloud. In the case of ICBMs, the cloud may be as large as across and long. While the midcourse provides the longest time to perform an interception, it is also the most difficult time to do so due to the presence of the extended cloud.
|
|
The European Interceptor Site (EIS) of the US was planned in nearby Redzikowo, forming a Ground-Based Midcourse Defense system in conjunction with a US narrow-beam midcourse tracking and discrimination radar system in the Czech Republic. It was supposed to consist of up to 10 silo-based interceptors, a two-stage version of the existing three-stage Ground Based Interceptor (GBI), with Exoatmospheric Kill Vehicle (EKV). The missile shield has received much local opposition in the area, including several protests. This included a protest in March 2008, when an estimated 300 protesters marched on the proposed site of the missile base.

At 073:31:14 into the mission, a second midcourse correction, with less than a second of burn, was made. Although there were four opportunities to make midcourse corrections following TLI, only two were needed. Apollo 15 approached the Moon on July 29, and the lunar orbit insertion (LOI) burn had to be made using the SPS, on the far side of the Moon, out of radio contact with Earth. If no burn occurred, Apollo 15 would emerge from the lunar shadow and come back in radio contact faster than expected; the continued lack of communication allowed Mission Control to conclude that the burn had taken place.

Communications consisted of a 3-watt transmitter capable of continuous telemetry operation, the large high gain directional dish antenna, a cylindrical omnidirectional antenna at the top of the instrument mast, and two command antennas, one on the end of either solar panel, which received instructions for midcourse maneuvers and other functions. Propulsion for midcourse maneuvers was supplied by a monopropellant (anhydrous hydrazine) 225 N retro-rocket. The hydrazine was ignited using nitrogen tetroxide and aluminum oxide pellets, and thrust direction was controlled by four jet vanes situated below the thrust chamber. Attitude control with a 1 degree pointing error was maintained by a system of nitrogen gas jets.

The United States missile defense complex in Poland, also called the European Interceptor Site (EIS), was a planned American missile defense base. It was intended to contain 10 silo-based interceptors: two-stage versions of the existing three-stage Ground-Based Interceptors with Exoatmospheric Kill Vehicles that had a closing speed of about 7 km/s. The first planned complex was to be located near Redzikowo, Poland, forming a Ground-Based Midcourse Defense system in conjunction with a U.S. narrow-beam midcourse tracking and discrimination radar system located in Brdy, Czech Republic. EIS was cancelled in 2009 and subsequently replaced with a phased plan--the Aegis Ballistic Missile Defense System, which will include SM-3 Block IIA interceptors to be positioned in Poland from 2018.

During 2001, 127 Johanna was observed by radar from the Arecibo Observatory. The return signal matched an effective diameter of 117 ± 21 km. A larger diameter value of 123.41 ± 4.07 km was obtained from the Midcourse Space Experiment observations, with an albedo of 0.0557 ± 0.0039. A 2012 study gave a refined diameter estimate of 116.14 ± 3.93 km.

Targets long-range ICBMs, which travel at about 7 km/s (15,700 mph). Examples of currently active systems: Russian A-135 system which defends Moscow, and the U.S. Ground-Based Midcourse Defense system that defends the United States from missiles launched from Asia. Geographic range of strategic defense can be regional (Russian system) or national (U.S. system).

From here, the track makes an uphill right turn into the mid-course brake run. Off the midcourse brakes, the track drops into a Corkscrew, and finish off with a figure-eight turn. The train then enters the final brake run, and then makes a right turn, passing through the transfer track before returning to the station.

At 60:30 Ground Elapsed Time, Shepard and Mitchell entered the LM to check its systems; while there they photographed a wastewater dump from the CSM, part of a particle contamination study in preparation for Skylab. Two midcourse corrections were performed on the translunar coast, with one burn lasting 10.19 seconds and one lasting 0.65 seconds.

Kugel reported that Jacob then blessed his two new sons, making another midcourse correction in . Jacob's blessing promoting Ephraim to the firstborn reflected the later dominance of the originally less powerful people; whereas Manasseh originally dominated Ephraim, an Ephraimite, Jeroboam, eventually took control of the whole population of the north, including Manasseh (as reported in and ).James L.

The target area proposed was within Sinus Medii. The Atlas-Centaur had placed Surveyor 2 on a path to the Moon that was only 130 km from its aim point. During the midcourse correction maneuver, one vernier thruster failed to ignite, resulting in an unbalanced thrust that caused the spacecraft to tumble for its remaining 54 hours. Attempts to salvage the mission failed.

This was an advanced pulse-Doppler radar system with a maximum range against bomber-sized targets at about , and was able to track eight targets at a time in its track while scan mode at up to . The radar also broadcast midcourse corrections to the missiles, and was in charge of calculating their lofted trajectories. The range of the AN/APQ-81 meant the Eagle could not be fired at its maximum effective range of , but the Eagle also had a home-on-jam capability that allowed it to attack targets at its maximum range, although this was reduced in practice as it did not use midcourse corrections and flew directly at the target at lower altitudes. To support the fighters, an improved early warning radar aircraft was needed, and Grumman won the contract with the W2F Hawkeye.

The track then races through a wooden tunnel, which until recent years, had cameras for an on-ride photo (it has since been removed due to the two inside seats not being clear in the photos), before passing through a cobra roll over the Rhine River, adjacent to the Loch Ness Monster. Out of the cobra roll, the track crosses over the entrance to the cobra roll, passes by Griffon, then rises into the midcourse brake run. After the midcourse brakes, the track crosses over the exit from the Immelmann loop and then down a drop before entering a zero-g roll, alongside the Le Scoot log flume. After a short section of straight track close to ground level, the track goes through a corkscrew followed by a clockwise upward helix, before making a left turn to the final brake run.

The current modules are concentrated toward the center to minimize grating lobes. This configuration allows it to support the very-long-range target discrimination and tracking that GMD's midcourse segment requires. The radar is never pointed at land, for the safety of the inhabitants. In addition to the power consumed by the radar, the thrusters which propel the vessel are electric and require substantial power.

Viper Strike Scores Direct Hits in US Army-Northrop Tests - Deagel.com, April 9, 2003 In June 2005, Northrop integrated the Global Positioning System (GPS) into the laser-guided munition to provide highly accurate midcourse guidance. This allowed the weapon to be launched from much greater altitude and standoff range. During tests, an unarmed weapon successfully acquired GPS data after dispensing from an aircraft and flew to pre-assigned GPS waypoints.

The missile's fuselage was constructed from aluminum alloy, while the nosecone and control fins were molded from plastic.Popular Science, January 1950, p.144. Firebird was fitted with a solid-fuel booster rocket providing initial thrust, before a liquid-fuel sustainer rocket ignited for a 15-second powered flight time. Guidance was provided during midcourse flight by radio command, with an operator in the launching aircraft transmitting corrections to the missile.
|
|
In these cases, some other form of guidance is used to get the missile into the range where the signal is stronger. Examples would be radio control (command guidance) or inertial guidance systems, which fly the missile closer to the target. In this role, these are known as "midcourse guidance" systems. In practice, terminal guidance systems are often optical or active radar systems, in an effort to greatly increase accuracy.

Normal operation never resumed; battery power was depleted after 8 hours, and all spacecraft systems died. The first midcourse correction was never implemented, and Ranger 5 passed the Moon at a range of 724 kilometers on October 21 and entered heliocentric orbit. It was tracked to a distance of 1,271,381 kilometers. Before loss of signal, the spacecraft sent back about 4 hours of data from the gamma-ray experiment.

The mid-infrared image of the Moon was taken during a September 1996 lunar eclipse by the SPIRIT-III instrument aboard the orbiting Midcourse Space Experiment (MSX) satellite. On the Moon, they are seen as solar eclipses. At these wavelengths, MSX was able to characterize the thermal (heat) distribution of the lunar surface during the eclipse. The brightest regions are the warmest, and the darkest areas are the coolest.

The listener has to attend to, hear, and try to understand an utterance at virtually the same time it is being issued. That requires a type of process synchronization not found in reading. And third, listeners in conversations aren’t mute or invisible during an utterance. Speakers may alter what they say midcourse based on what addressees say and do.” In the same paper, they proposed the Collaborative Model as an alternative.

South Korea's DAPA Orders Additional PKX-B Fast Attack Craft for ROK Navy - Navyrecognition.com, 28 June 2017 The PKX-B was specifically designed to counter North Korean fast swarming crafts. The 12-canister 130 mm guided rocket launcher can hit targets between using a rocket weighing with an warhead. Rockets have GPS/INS midcourse guidance with data uplink and terminal IIR homing, and three can be fired simultaneously.

Countermeasures are a complicating factor in the development of anti-ballistic missile defense systems targeting ICBMs. Like aircraft, ICBMs theoretically could evade such systems by deploying decoys and chaff in the midcourse phase of flight. Novel proposed chaff mechanisms describe the creation of a "threat cloud" by deploying large aluminized PET film balloons which could conceal a warhead among a large number of inert objects having similar radar profiles.

Israel Aircraft Industries refers to the system as Barak-8. IAI states that the missile will have a dual pulse motor, is vertically launched and is able to engage both aircraft and sea skimming missiles. It has a fully active seeker, and the Barak-8 Weapons system is capable of multiple simultaneous engagements. It will have a two way datalink for midcourse update, as well as be able to integrate into larger C3I networks.

Luna 4 was launched by a Molniya-L carrier rocket at 08:16:37 UTC on April 2, 1963. Launch occurred from Site 1/5 at the Baikonur Cosmodrome. After reaching an initial parking orbit of , the rocket's upper stage restarted to place Luna 4 onto a translunar trajectory. The spacecraft did not perform a required midcourse correction manoeuvre, which resulted in it missing the Moon by at 1:24 UT on April 5, 1963.

In 2017, India had lost contact to one of its key imaging satellites, RISAT-1. In 2016, the Indian Government approved a program codenamed Project XSV-1 for an ASAT test. A modified version of the PDV similar to the midcourse ground-based interceptor, officially named PDV MkII was tested against a satellite on 27 March 2019. DRDO has also been working on directed energy weapons, electromagnetic pulse and co-orbital weapons for ASAT roles.

After that, the crew determines the number of launched vehicles and provides impact predictions on North America. Once the information is determined, the unit passes updates to the appropriate authorities. The 7th SWS's corollary mission of Missile Defense supports the Ground-Based Midcourse Defense (GMD) element of the Ballistic Missile Defense System. This program's objective is the defense of the United States against a threat of a limited strategic ballistic missile attack.

The SSN included one spaceborne sensor, the space-based visible (SBV) sensor, carried into orbit aboard the Midcourse Space Experiment (MSX) satellite launched by the Ballistic Missile Defense Organization in 1996. It was retired from service on June 2, 2008. The Space Based Space Surveillance (SBSS) pathfinder satellite now performs the mission previously handled by the MSX SBV. The Canadian military satellite Sapphire, launched in 2013, also contributes data to the SSN.

The development of ERIS came late in the Cold War. After the collapse of the Soviet Union, and effective end of the Cold War, the Strategic Defense Initiative was reorganized. ERIS was cancelled as part of the reorganization, and the system was never directly implemented. However, technology developed from ERIS is currently used in other U.S. missile defense systems, including Terminal High Altitude Area Defense (THAAD) and Ground-Based Midcourse Defense (GMD).

SBX-1 is part of the Ground-Based Midcourse Defense (GMD) system under development by the Missile Defense Agency (MDA). The decision to place the system on a mobile sea-based platform was intended to allow the vessel to be moved to areas where it is needed for enhanced missile defense. Fixed radars provide coverage for a very limited area due to the curvature of the Earth. However, the same limitation applies to the SBX.

Following an extended, nearly horizontal midcourse flight, the GPS-enhanced munition switched over to the semi-active laser seeker once it entered the target area to detect and track the laser-designated target.Greater Launch Altitude for Viper Strike - Deagel.com, June 15, 2005 In January 2007, Viper Strikes successfully destroyed a series of moving and stationary targets in testing at the White Sands Missile Range. They were guided to their targets by the Hunter UAV's laser targeting system.

The seeker uses a simple inertial guidance system through the midcourse, and homes during the terminal approach using a laser designator. Other versions offer anti-radiation seeking, or GPS guidance. The precision guided kit includes the addition of tail fins and an in-flight control system. Combining the laser seeker with the FAT warhead produces a capable long-range anti-tank missile that is faster and much less expensive than traditional platforms like the AGM-114 Hellfire.

Its drainage basin was once the site of extensive cotton plantings, which have been greatly diminished in recent decades by extensive urbanization of the area. The Loosahatchie rises in the westernmost part of Hardeman County, Tennessee, and flows largely east to west throughout its length. It enters Fayette County, Tennessee, flowing through Somerville, and is crossed west of there by Interstate 40 in the only unchannelized portion of its midcourse. It then flows into Shelby County.

U.S. President Barack Obama proposed using the Aegis Ballistic Missile Defense System (including ship borne launchers) in 2009, replacing a planned Ground- Based Midcourse Defense system deployed in Poland and the Czech Republic. The NATO missile defense system is a missile defense system being constructed by the North Atlantic Treaty Organization (NATO) in several member states and around the Mediterranean Sea. Plans for this system have changed several times since first studied in 2002, including as a response to Russian opposition.

Apollo 13's final midcourse correction had addressed the concerns of the Atomic Energy Commission, which wanted the cask containing the plutonium oxide intended for the SNAP-27 RTG to land in a safe place. The impact point was over the Tonga Trench in the Pacific, one of its deepest points, and the cask sank to the bottom. Later helicopter surveys found no radioactive leakage. Ionization of the air around the command module during reentry would typically cause a four-minute communications blackout.

The Kinetic Energy Interceptor (KEI) was a planned U.S. missile defense program whose goal was to design, develop, and deploy kinetic energy-based, mobile, ground and sea-launched missiles that could intercept and destroy enemy ballistic missiles during their boost, ascent and midcourse phases of flight. The KEI consisted of the Interceptor Component (kinetic projectile), the Mobile Launcher Component, and the Command, Control, Battle Management, and Communications (C2BMC) component. On 7 May 2009, the KEI program was canceled due primarily to financial reasons.

Several aspects of the defense program have either sought or achieved participation and assistance from other nations. Several foreign navies are participating in the Aegis Ballistic Missile Defense, including Japan and Australia. Also, the United States has considered establishing radar sites and missile sites in other nations as part of the Ground-Based Midcourse Defense. A missile defense site in Poland received much media attention when it was cancelled in favor of the Aegis BMD.Q&A;: US missile defence, BBC, 9/20/09.

Telemetry data suggested a separation failure of either the Agena or the payload fairing, but a below-normal velocity appeared to indicate that the fairing had not separated properly. A command was sent to manually jettison the payload shroud, but nothing happened. The ground controllers next considered firing Mariner 3's midcourse correction engine to blow off the shroud, but they ran out of time. Eight hours after launch, the batteries in the probe died and the mission was officially terminated.

The track then takes a dive off the midcourse brakes, followed by a tall turnaround. Following this, the track makes a right turn, passes under the lift hill, and over a pair of smaller airtime hills with slight right turns, before making a 180 degree banked turnaround, leading into a bunny hop and the final brake run. This is concluded with a left hand turn to return to the station. Prior to the 2018 season, the final turnaround was a 570 degree double helix.
|
|
Following the second helix, the track maneuvers through the supports of the first helix and third hill and makes a left turn into the midcourse brakes, which start the return trip. The return trip consists of a series of airtime hills, running parallel to the outbound track, before hitting the final brake run next to the base of the lift hill. From the brake run, trains pass through the transfer track and storage area before making a sweeping left turn to return to the station.

The missile would use an inertial guidance system with terminal guidance provided by active radar homing - a mode of flight that would later be employed in the AIM-120 AMRAAM. An infrared terminal homing seeker was also planned, which would allow the missile to engage without any emissions which would alert the target. The GD/Westinghouse design was even smaller, with a multiple-pulse pure solid rocket motor. It also had an inertial guidance system, but midcourse updating was provided via a dual-band semi-active radar.

Noting the absence of Simeon from , Kugel explained that modern scholars see a midcourse correction in Israel's list of tribes in Jacob's adoption of Ephraim and Manasseh in . That there were 12 tribes seems to have become unchangeable at an early stage of Israel's history, perhaps because of the number of lunar months in a year. But, at some point, Simeon disappeared. So to compensate for its absence, the Israelites counted the territory elsewhere attributed to Joseph as two territories, each with its own ancestor figure.

An anti-ballistic missile is a missile which can be deployed to counter an incoming nuclear or non-nuclear ICBM. ICBMs can be intercepted in three regions of their trajectory: boost phase, mid-course phase or terminal phase. Currently China, the US, Russia, France, India and Israel have developed anti-ballistic missile systems, of which the Russian A-135 anti-ballistic missile system and the US Ground-Based Midcourse Defense systems have the capability to intercept ICBMs carrying nuclear, chemical, biological, or conventional warheads.

Military use of the Brdy mountains gradually decreased after the Velvet Revolution in 1989, as a result of military cost-cutting and eventual professionalization in 2005. However, the central part of the Brdy mountain area retains its restricted military status. The Brdy mountains were a focus of negotiations with American negotiators attempting to agree a deal with Czech government to install a Ground-Based Midcourse Defense missile defense radar system in the military area. However, the missile defence plans were reshaped during the Obama administration and the plan was cancelled.

Joan Johnson- Freese. Heavenly Ambitions: America's Quest to Dominate Space. p. 12 A classified U.S. State Department cable revealed by WikiLeaks indicates that the same system was tested against a ballistic target in January 2010 in what the Chinese government publicly described as a test of "ground-based midcourse missile interception technology". That description also closely matches the Chinese government's description of another test in January 2013, which has led some analysts to conclude that it was yet another test of the same ASAT system, again against a ballistic target and not a satellite.

It was propelled by a Klimov RD-500K turbojet engine, reverse-engineered from the Rolls-Royce Derwent engine. Guidance was provided by an inertial navigation system (INS) in the midcourse phase, and by a semi-active radar in the terminal phase which directed the missile to its target. A 600 kg high explosive (HE) armour- piercing warhead was carried. The AS-1 is believed to have entered service in 1955, initially being deployed on the Tu-4 and later on the Tu-16KS 'Badger-B' strategic bomber, on two under-wing pylons.

The 7½ month flight of Mariner 4 involved one midcourse maneuver on December 5, 1964. The maneuver was initially scheduled for December 4, but due to a loss of lock with Canopus, it was postponed. The maneuver was successfully completed on December 5; it consisted of a negative pitch turn of 39.16 degrees, a positive roll turn of 156.08 degrees, and a thrusting time of 20.07 seconds. The turns aimed the motor of the spacecraft back in the general direction of Earth, as the motor was initially pointed along the direction of flight.

Exoatmospheric Kill Vehicle prototype The Exoatmospheric Kill Vehicle (EKV) is the Raytheon-manufactured interceptor component with subcontractor Aerojet of the U.S. Ground-Based Midcourse Defense (GMD), part of the larger National Missile Defense system. The EKV is boosted to an intercept trajectory by a boost vehicle (missile), where it separates from the boost vehicle and autonomously collides with an incoming warhead. The EKV is launched by the Ground-Based Interceptor (GBI) missile, the launch vehicle of the GMD system. The EKV's own rockets and fuel are for corrections in the trajectory, not for further acceleration.

The expected propellant cloud enveloped the booster, but no anomalous events occurred this time. Thirty minutes after liftoff, the Agena restarted to boost Ranger 7 on a trajectory towards the Moon. The flight trajectory for Ranger 7 was quite accurate, but a short midcourse correction would still be needed to ensure impact in the Sea of Storms instead of the far side of the Moon, which was carried out early on the morning of July 29. The warmup period for the TV cameras would be performed earlier and made shorter than on Ranger 6.

While the Reagan era Strategic Defense Initiative was intended to shield against a massive Soviet attack, during the early 1990s, President George H. W. Bush called for a more limited version using rocket-launched interceptors based on the ground at a single site. Such system was developed since 1992, was expected to become operational in 2010 and capable of intercepting small number of incoming ICBMs. First called the National Missile Defense (NMD), since 2002 it was renamed Ground-Based Midcourse Defense (GMD). It was planned to protect all 50 states from a rogue missile attack.

The only person on record ever hit by space debris was hit by a piece of a Delta II rocket. Lottie Williams was exercising in a park in Tulsa on January 22, 1997 when she was hit in the shoulder by a six-inch piece of blackened metallic material. U.S. Space Command confirmed that a used Delta II rocket from the April 1996 launch of the Midcourse Space Experiment had crashed into the atmosphere 30 minutes earlier. The object tapped her on the shoulder and fell off harmlessly onto the ground.

The turnaround starts the second half of the ride. Diving off a straight section which was where midcourse brakes used to be, riders descend a steep drop, making a left-hand turn, rising over an airtime hill, before making a right-hand turnaround underneath the turnaround in the first half. After rising over another airtime hill, the trains enter a 450-degree downward helix to the right, before rising over a final hill and hitting the final brake run. The ride follows an L-shaped double out and back pattern.

The land based version of the TC-2N features the missile packaged in a sealed container-launcher. NCSIST has exhibited a truck mounted version with four missile pods. The TC-2 air-defense system was exhibited at International Defence Exhibition in Abu Dhabi with a reported canister length of 4m and an all up weight (combined canister and round) of 350kg. It reportedly has midcourse inertial guidance with data link and terminal active radar guidance and electronic counter-countermeasure (EECM) and protection, but a reported effective range of only 15km.

Realino began his studies in philosophy and medicine in Bologna but altered this midcourse to law; it was said that a woman he fell in love with persuaded him to do so on the assumption that Realino would be good at practicing law. It also offered greater opportunities for advancement and wealth. He graduated with a doctorate in law – both civil and canon law – at the Bologna college in 1556. Through his family's influence, in 1556 he was appointed as the podestà of both the Cassine and Felizzano cities – he served as a judge in Felizzano.

Out of the station, the track passes through the transfer track, and makes a slight left turn before making a right hand turn to climb the lift hill. At the top of the lift hill, the track makes a left turn and dives down a drop into a ravine, leveling out as it zooms through the structure of the third hill and rises into an elevated turnaround. It then dives down a drop back into the ravine, and rises up a third hill. At the top of the hill, the track makes a level right hand turn into the midcourse brakes.

The gamma ray detector was turned on, but the computer did not issue the command to align the spacecraft with Earth. Then the telemetry receivers at the tracking stations in Australia and South Africa malfunctioned, returning garbled data. It was obvious that an electrical short had disabled the solar panels, which meant that Ranger 5 now had only a few hours before it would run out of battery power. JPL technicians thought that they could still partially salvage the mission by firing the midcourse correction engine to ensure impact with the Moon, but they had to do it quickly before power ran out.

The Northern Warfare Training Center also continued operations at Black Rapids Training Facility. After the United States announced that it would withdraw from the Anti-Ballistic Missile Treaty, Fort Greely was selected as a site for the Ground-Based Midcourse Defense system. Starting in the summer of 2002, the United States government began work on the missile defense installation at Fort Greely, planning to deploy a total of 25 to 30 anti-ballistic missiles by 2010. Concurrently, the Missile Defense Command took command of Fort Greely, relinquishing direct Army control, while the Army retained control of the nearby Donnelly Training Area.

Early seekers did not image the target, and anything within their FOV would create an output. A flare released by the target causes a second signal to appear within the FOV, producing a second angle output, and the chance that the seeker will begin to aim at the flare instead. Against early spin-scan seekers this was extremely effective because the signal from the target was minimized through the midcourse, so even a dim signal from the flare would be seen and tracked. Of course if this happens, the flare now disappears from view and the aircraft becomes visible again.

Late in 1957, the Royal Aircraft Establishment began work with both Bristol Aerospace and Ferranti for alternatives to the EE/Marconi designs. Bristol responded in early 1958 with the first definitive design for such a system. This would use the Red Duster Series 2 Mark 2, later to be known as Bloodhound Mk. 3, combined with the Type 85 radar for early warning, Type 86 for terminal tracking and FPS-16 for midcourse tracking. In action, the Type 85 would detect the missile while it was launching, and then cue one of the UK-based FPS-16's onto it.

Like the operator's telescope, the TV system has two views, one about 11 degrees wide for the initial "capture", and another at 0.55 degrees for midcourse tracking. The difference between the line-of-sight of the operator's telescope and the missile's flare is calculated by the computer in the base of the launcher. Guidance updates are sent to the missile through the transmitter on the launcher platform and received on small antennas on the rear of the mid-body fins. The operator simply keeps the telescope's crosshairs on the target using the joystick, and the missile automatically flies into the line-of-sight.

Luna 19 was the first of the “advanced” lunar orbiters whose design was based upon the same Ye-8-class bus used for the lunar rovers and the sample collectors. For these orbiters, designated Ye-8LS, the basic “lander stage” was topped off by a wheelless Lunokhod-like frame that housed all scientific instrumentation in a pressurized container. Luna 19 was launched into an Earth parking orbit on 28 September, and, from this orbit, was sent toward the Moon. Luna 19 entered an orbit around the Moon on 2 October 1971 after two midcourse corrections on 29 September and 1 October.

The Luna 10 spacecraft was launched towards the Moon from an Earth-orbiting platform on 31 March 1966. The spacecraft entered lunar orbit on 3 April 1966 and completed its first orbit 3 hours later (on 4 April Moscow time). After a midcourse correction on 1 April, Luna 10, the second of two hastily prepared Soviet Ye-6S probes (that is, the backup), successfully entered lunar orbit two days later at 18:44 GMT. A 245-kilogram instrument compartment separated from the main bus, which was in a 350 x 1,000-kilometer orbit inclined at 71.9° to the lunar equator.

Historical Documents: Reagan's 'Star Wars' speech , CNN Cold War The initiative focused on strategic defense rather than the prior strategic offense doctrine of mutual assured destruction (MAD). Though it was never fully developed or deployed, the research and technologies of SDI paved the way for some anti-ballistic missile systems of today. In February 2007, the U.S. started formal negotiations with Poland and Czech Republic concerning construction of missile shield installations in those countries for a Ground-Based Midcourse Defense system (in April 2007, 57% of Poles opposed the plan).U.S. Might Negotiate on Missile Defense, washingtonpost.

A Ground-Based Interceptor of the United States' Ground-Based Midcourse Defense system, loaded into a silo at Fort Greely, Alaska, in July 2004 An anti-ballistic missile (ABM) is a surface-to-air missile designed to counter ballistic missiles (missile defense). Ballistic missiles are used to deliver nuclear, chemical, biological, or conventional warheads in a ballistic flight trajectory. The term "anti-ballistic missile" is a generic term conveying a system designed to intercept and destroy any type of ballistic threat; however, it is commonly used for systems specifically designed to counter intercontinental ballistic missiles (ICBMs).

According to Arieh Herzog, block-4 upgrades "improve the process of discrimination of what happens in the sky and the transmission of target data for much better situational control." Block-4 upgrades also refine midcourse guidance which, when coupled with improved target identification and discrimination capabilities, improves lethality. Block-4.1 is expected to include a new Battle Management Center, armored launchers with high shooting availability, better communication with other missile systems and wider ranges of interceptions. On September 9, 2014 an intercept test was conducted over the Mediterranean Sea with block-4.1 versions of the operational system.

Professor James Kugel of Bar-Ilan University read to tell that Jacob legally adopted Joseph's sons Ephraim and Manasseh as his own, making them coequal heirs with Jacob's other sons. Thus, while Joseph formerly was entitled to one-twelfth of Jacob's estate, after , Jacob replaced Joseph's single share with the two shares of Ephraim and Manasseh, giving Joseph in effect a double portion. Kugel reported that modern scholars see behind this incident a midcourse correction in Israel's list of tribes. At an early stage, it had become fixed that there were 12 tribes, but then reality changed.

Modern armed forces use chaff (in naval applications, for instance, using short-range SRBOC rockets) to distract radar-guided missiles from their targets. Most military aircraft and warships have chaff dispensing systems for self-defense. An intercontinental ballistic missile may release in its midcourse phase several independent warheads as well as penetration aids such as decoy balloons and chaff. Modern radar systems can distinguish chaff from target objects by measuring the Doppler shift; chaff quickly loses speed compared to an aircraft and thus shows a characteristic change in frequency that allows it to be filtered out.

Programs at these facilities included the V-22 Osprey, CH-47 Chinook, and the AH-64D Apache. Shanahan served as vice president and general manager of Boeing Missile Defense Systems, starting in December 2004 overseeing the Ground-based Midcourse Defense system, Airborne Laser and Advanced Tactical Laser programs. He served as vice president and general manager of the Boeing 787 Dreamliner program, where he led the program during a period of the aircraft's development from 2007 to 2008. He next served as senior vice president of Airplane Programs at Boeing Commercial Airplanes, beginning in December 2008.

In May 1996, satellite command authority for the first research and development satellite controlled by AFSPC, Technology for Autonomous Operational Survivability, was given to 1st SOPS. On 4 December 1998, the squadron assumed command and control capability on the Midcourse Space Experiment, which became an operational program on 1 October 2000, with the first-ever transfer of operations from the Ballistic Missile Defense Organization to AFSPC.

In a vertical flight of not too high altitudes, the time of the free-fall is both for the upward and for the downward part the maximum speed divided by the acceleration of gravity, so with a maximum speed of 1 km/s together 3 minutes and 20 seconds. The duration of the flight phases before and after the free-fall can vary. For an intercontinental flight the boost phase takes 3 to 5 minutes, the free-fall (midcourse phase) about 25 minutes. For an ICBM the atmospheric reentry phase takes about 2 minutes; this will be longer for any soft landing, such as for a possible future commercial flight.

"Raytheon's SM-6 Surface-to-Air Missile moves from low-rate to full-rate production" – Navyrecognition.com, 6 May 2015 On 28 July 2015, the Navy tested the modified SM-6 Dual I version to successfully intercept a ballistic missile target in the terminal phase, the last few seconds before it would impact; the Dual I upgrade adds a more powerful processor that runs more sophisticated targeting software to hit a warhead descending from the upper atmosphere at extreme speed. This adds to the fleet's missile defense capabilities by allowing it to intercept ballistic missiles that could not be hit by SM-3 missiles, which targets missiles in the midcourse phase.

The current director is U.S. Navy Vice Admiral Jon A. Hill. Rapid changes in the strategic environment due to the rapid Dissolution of the Soviet Union led, in 1993, to Bill Clinton focusing on theater ballistic missiles and similar threats, and renaming it the Ballistic Missile Defense Organization, BMDO. With another change to a more global focus made by George W. Bush, in 2002 the organization became the Missile Defense Agency. The Missile Defense Agency is partially or wholly responsible for the development of several ballistic missile defense (BMD) systems, including the Patriot PAC-3, Aegis BMD, THAAD and the Ground- Based Midcourse Defense system.

The launch vehicle had placed the probe on an accurate enough flight path that only a short midcourse correction burn would be required. However, the activation of the TV camera telemetry during launch remained a cause for concern. JPL technicians wanted to turn the camera on to verify its operability, however, they were running the risk of not being able to turn it off again if an electrical short had indeed occurred somewhere. Since the camera had its own batteries and did not use the probe's main power bus, they would be depleted before it could get to the Moon and eliminate any chance of returning pictures.

However, in June 2001, the MoD signed a contract for a further upgrade to allow for these midcourse updates. This upgrade, together with updated IFF, was known as the AMRAAM Optimisation Programme (AOP) and was incorporated in the remaining F3 fleet between December 2003 and September 2006. A further upgrade, disclosed in early 2003, was the integration of the ALARM anti-radiation missile to enable several Tornado ADVs to conduct Suppression of Enemy Air Defenses (SEAD) missions. The F3's existing radar warning receivers formed the basis of an Emission Location System (ELS), which can be employed to detect and locate operational radar systems in the aircraft's vicinity.

The LSFW missile was required to be equally as effective against soft targets as the naval guns and the unguided rockets that it was intended to replace. Studies regarding the guidance system of the LFSW were conducted by the Applied Physics Laboratory, which determined that the ideal solution for the new missile was for it to utilise inertial guidance during the midcourse phase of its flight. Terminal guidance would be provided by a tracking beacon, operated by the troops in the battle area. The missile, having locked onto the beacon, would offset from the beacon's position by an amount specified in the beacon signal, thereby striking the target with a high degree of accuracy.

Instruments aboard the spacecraft included a Lyman-alpha telescope, a rubidium-vapor magnetometer, electrostatic analyzers, medium-energy range particle detectors, two triple coincidence telescopes, a cosmic-ray integrating ionization chamber, cosmic dust detectors, and solar X-ray scintillation counters. There was no camera or midcourse correction engine on the Block I spacecraft. The communications system included the high-gain antenna and an omnidirectional medium-gain antenna and two transmitters, one at 960.1 MHz with 0.25 watts power output and the other at 960.05 MHz with 3 watts power output. Power was to be furnished by 8680 solar cells on the two panels, a silver-zinc battery, and smaller batteries on some of the experiments.

White paint, gold and chrome plating, and a silvered plastic sheet encasing the retrorocket furnished thermal control. During prelaunch preparations for Ranger 1, the spacecraft's timer had accidentally been started which led to the deployment of the solar panels inside the payload shroud. It was decided that ground testing of the onboard instruments would not be done on the Block II spacecraft because they had a functional midcourse correction engine and if a similar incident happened with them, the squibs and pyrotechnics used to deploy the solar panels could inadvertently ignite the propellants in the onboard engine, which could result in the explosion of the spacecraft on the pad and possibly take the entire launch vehicle with it.

The function of GMD is to provide combatants the ability to seek and destroy intermediate and long range ballistic missiles en route to the US homeland via Ground-based Midcourse Defense systems (GBI). Data is transmitted from the Defense Satellite Communication System (DSCS), and compiles an image using the coordinated information. The GFC is able to relay real-time data once GBI missiles have been launched. The GMD can also work to receive information from the C2BMC which allows Aegis SPY-1, and TPY-2 to contribute to the defense system A problem with GMD is that the ground systems have increasingly becoming obsolete as the technology was initially installed as early as the 1990s.

NGC 6357 is a diffuse nebula near NGC 6334 in the constellation Scorpius. The nebula contains many proto-stars shielded by dark disks of gas, and young stars wrapped in expanding "cocoons" or expanding gases surrounding these small stars. It is also known as the Lobster Nebula and the Madokami Nebula by some fans of the anime Madoka Magica due to its resemblance to the main character from the anime and a popular fan petition to rename it. This nebula was also given the name War and Peace Nebula by the Midcourse Space Experiment scientists because of its appearance, which, in infrared images the bright, western part resembles a dove, while the eastern part looks like a skull.

They decided that it was not worth compromising the mission and the camera would not be touched until descent to the Moon began. Early on the morning of January 31, the command was sent to fire the midcourse correction engine, which performed flawlessly and set the probe on an impact course with the Sea of Tranquility. On February 2, JPL technicians prepared for the final phase of the mission. Ranger 6 began its descent and trajectory calculations determined that impact would occur close to the intended area. With the probe's angle suitable for taking images, the order was given to turn on the camera with 13 minutes and 10 seconds until impact.

Rogozin also stated that the Russian Fund of Perspective Researches (FPI) would develop a military response to the PGS system. In September 2014, Russia's president Vladimir Putin mentioned PGS among a number of the new threats Russia faced, along with the US Ground-Based Midcourse Defense system in Alaska, the Aegis Ballistic Missile Defense System in Europe, and increased NATO activity in eastern Europe. Deputy prime minister Dmitry Rogozin again warned that Russia would upgrade its strategic nuclear forces and aerospace defences in response to the PGS system. According to some observers, the Russian Yu-71 hypersonic boost-glide system is under test flights since 2011, though its predecessors date back to 2001.

The Modular Midcourse Package (MMP), which is located in the forward portion of the warhead section, consists of the navigational electronics and a missile-borne computer that computes the guidance and autopilot algorithms and provides steering commands according to a resident computer program. The warhead section, just aft of the guidance section, contains the proximity fused warhead, safety-and-arming device, fuzing circuits and antennas, link antenna switching circuits, auxiliary electronics, inertial sensor assembly, and signal data converter. The propulsion section consists of the rocket motor, external heat shield, and two external conduits. The rocket motor includes the case, nozzle assembly, propellant, liner and insulation, pyrogen igniter, and propulsion arming and firing unit.

A site similar to the US base in Alaska would help protect the US and Europe from missiles fired from the Middle East or North Africa. Poland's prime minister Kazimierz Marcinkiewicz said in November 2005 he wanted to open up the public debate on whether Poland should host such a base.BBC. US considers Polish missile base. 17 November 2005 In 2002, NMD was changed to Ground-Based Midcourse Defense (GMD), to differentiate it from other missile defense programs, such as space- based, sea-based, and defense targeting the boost phase and the reentry phase (see flight phases). On 22 July 2004, the first ground-based interceptor was deployed at Fort Greely, Alaska ().

Considering the ICBM problem, the study went on to suggest that the system would have to be effective between 95 and 100% of the time in order to be worthwhile. They considered attacks against the RV while the missile was in the midcourse, just as it reached the highest point in its trajectory and was traveling at its slowest speed. Practical limitations eliminated this possibility, as it required the ABM to be launched at about the same time as the ICBM in order to meet in the middle, and they could not imagine a way to arrange this. Working at much shorter ranges, during the terminal phase, seemed the only possible solution.

The SM-3 evolved from the proven SM-2 Block IV design. The SM-3 uses the same solid rocket booster and dual thrust rocket motor as the Block IV missile for the first and second stages and the same steering control section and midcourse missile guidance for maneuvering in the atmosphere. To support the extended range of an exo-atmospheric intercept, additional missile thrust is provided in a new third stage for the SM-3 missile, containing a dual pulse rocket motor for the early exo-atmospheric phase of flight. Initial work was done to adapt SM-3 for land deployment ("Aegis ashore") to especially accommodate the Israelis, but they then chose to pursue their own system, the NATO code-name Arrow 3.

A consistent problem that plagued the spacecraft during the early portion of its mission was that roll error signal transients would occur frequently and on occasion would cause loss of the Canopus star lock. The first attempt at a midcourse maneuver was aborted by a loss of lock shortly after the gyros began spinup. Canopus lock was lost six times within a period of less than three weeks after launch and each time a sequence of radio commands would be required to reacquire the star. After a study of the problem, the investigators concluded that the behavior was due to small dust particles that were being released from the spacecraft by some means and were drifting through the star sensor field-of-view.

Ranger 6 was launched into an Earth parking orbit and injected on a lunar trajectory by a second Agena burn. The midcourse trajectory correction was accomplished early in the flight by ground control. On February 2, 1964, 65.5 hours after launch, Ranger 6 impacted the Moon on the eastern edge of Mare Tranquillitatis (Sea of Tranquility in English). The orientation of the spacecraft to the surface during descent was correct, but no video signal was received and no camera data obtained. A review board determined the most likely cause of failure was due to an arc-over in the TV power system when it inadvertently turned on for 67 seconds approximately 2 minutes after launch during the period of booster-engine separation.

The RIM-101 missile was planned to be a tube-launched weapon, a small ejector charge being used to propel the missile from its launching tube before ignition of a solid-fueled rocket sustainer, based on that of the FIM-43 Redeye SAM. Midcourse guidance of the new missile was planned to be of the semi-active radar homing type, using an I-band radar system, while terminal guidance would be provided by an infrared seeker. However, the RIM-101 project was cancelled early in the design-and-development stage, before any hardware had been built. It has been speculated that the RIM-101 was intended to be an advanced development of the RIM-7 Sea Sparrow missile, then in U.S. Navy service as the Basic Point Defense Missile System.

A common countermeasure that attacking parties use to disrupt the efficacy of Missile Defense Systems are the simultaneous launching of decoys from the primary launch site or from the exterior of the main attacking missile itself. These decoys are usually small, lightweight dud rockets that take advantage of the interceptor sensors tracking and fool it by making many different targets available in an instant, This accomplished via the releasing of decoys in certain phases of flight. Because objects of differing weights follow the same trajectory when in space, decoys released during the midcourse phase can prevent interceptor missiles from accurately identifying the warhead. This could force the defense system to attempt to destroy all incoming projectiles, which masks the true attacking missile and lets it slip by the defense system.

With that, the book could be closed on the cause of Ranger 6's failure. Among the changes made for Ranger 7 included new procedures to apply full power testing to the spacecraft off of the launch pad, where there was no risk of the midcourse correction engine activating on top of a fully fueled Atlas-Agena. Jet Propulsion Laboratory had originally wanted to have Ranger 7 impact in the same general area as Ranger 6 so the impact crater could be imaged, but lighting conditions during July would not be favorable so they instead decided to go for a little- known area 11 degrees south of the Moon's equator near the Sea of Storms. The probe was shipped to Cape Canaveral in mid-June along with Atlas 250D and Agena 6009.

Shambhala's splashdown After departing from the station, the train makes a 90 degree turn to the right, then begins to climb the tall chain lift hill. Once the train reaches the top of the lift, the train drops back down to the ground at a 77.4 degree angle reaching speeds of up to as it passes through a tunnel and races past the drop off Dragon Khan's midcourse brakes. Following the first drop, the train then makes a slight left turn into the first of five camelback hills before dropping again and entering a figure-8-like helix, also known as an ampersand turn. On the return trip, the train goes over a very small hill (speed hill); at the same time, passing through a trim brake which isn’t activated.

Pioneer P-31 (also known as Atlas-Able 5B or Pioneer Z) was intended to be a lunar orbiter probe, but the mission failed shortly after launch. The objectives were to place a highly instrumented probe in lunar orbit, to investigate the environment between the Earth and Moon, and to develop technology for controlling and maneuvering spacecraft from Earth. It was equipped to take images of the lunar surface with a television-like system, estimate the Moon's mass and topography of the poles, record the distribution and velocity of micrometeorites, and study radiation, magnetic fields, and low frequency electromagnetic waves in space. A midcourse propulsion system and injection rocket would have been the first United States self-contained propulsion system capable of operation many months after launch at great distances from Earth and the first U.S. tests of maneuvering a satellite in space.

Examination of telemetry records seemed to suggest that the failure had occurred during separation of Ranger 4 from the Agena, at the point where the electrical interface between the two was disconnected and Ranger 4 would have switched to internal power. The behavior of the probe indicated a transformer or inverter malfunction, probably a short circuit caused by loose metal coatings contacting the pins on the power umbilical attaching the probe to the Agena. Modifications to Ranger 5 included a backup timer to ensure continued operation of the telemetry system if the main computer failed, an additional nitrogen bottle to the attitude control system to reduce gas pressure, and an additional pyrotechnic igniter for the midcourse correction engine. Most importantly, extra diodes and fuses were added to the electrical lines to prevent another short from occurring.

The myth of Circe, Glaucus, and Scylla originates in Book XIV of Metamorphoses. The specific scene that Waterhouse bases this painting on occurs in lines 52–65 of the epic poem: > There was a cove, a little inlet shaped like a bent bow, a quiet place where > Scylla, at midday, sought shelter when the sea and sky were hot; and, in > midcourse, the sun scorched with full force, reducing shadows to a narrow > thread. And Circe now contaminates this bay, polluting it with noxious > poisons; there she scatters venom drawn from dreadful roots and, three- > times-nine times, murmurs an obscure and tangled maze of words, a labyrinth— > the magic chant that issues from her lips. Then Scylla comes; no sooner has > she plunged waist-deep into the water than she sees, around her hips, the > horrid barking shapes.

A ballistic missile goes through several distinct phases of flight that are common to almost all such designs. They are, in order, the boost phase when the main boost rocket or upper stages are firing, the post-boost phase when any last-minute changes to the trajectory are made by the upper stage or warhead bus and the warheads and any decoys are released, the midcourse which represents most of the flight when the objects coast, and the terminal phase as the warhead approaches its target and, for longer-ranged missiles, begins to reenter the atmosphere. These phases are particularly important when discussing ballistic missile defense concepts. Each phase has a different level of difficulty in performing an interception, as well as a different outcome in terms of its effect on the attack as a whole.

During this maneuver, Solovyev and Vinogradov opened a pressure regulation valve to allow air into the Spektr module to see if STS-89 crew members could detect seepage or debris particles that could indicate the location of the breach in the damaged module's hull. During the flight, Wetherbee and Bloomfield fired small jet thrusters on Atlantis to provide data for the Mir Structural Dynamics Experiment (MISDE), which measures disturbances to space station components and its solar arrays. Other experiments conducted during the mission were the Commercial Protein Crystal Growth investigation; the Cell Culture Module Experiment (CCM-A), the Cosmic Radiation Effects and Activation Monitor (CREAM) and the Radiation Monitoring Experiment-III (RME-III); the Shuttle Ionospheric Modification with Pulsed Local Exhaust (SIMPLE) experiment; and the Midcourse Space Experiment. Two NASA educational outreach programs were also conducted, Seeds in Space-II and KidSat.

In February 2007, the US started formal negotiations with Czech Republic and Poland concerning construction of missile shield installations in those countries for a Ground-based Midcourse Defense System. Government of the Czech Republic agrees (while 67% Czechs disagree and only about 22% support it) to host a missile defense radar on its territory while a base of missile interceptors is supposed to be built in Poland. The objective is reportedly to protect another parts of US National Missile Defense from long-range missile strikes from Iran and North Korea, but Czech PM Mirek Topolánek said the main reason is to avoid Russian influence and strengthen ties to US. The main government supporter Alexandr Vondra, Deputy Prime Minister for European affairs, used to be an ambassador to the USA. More problematic is that between 2004 and 2006 he was an executive director of a lobbying company Dutko Worldwide Prague.

Noting the absence of Levi from Professor James Kugel of Bar Ilan University explained that modern scholars see a midcourse correction in Israel's list of tribes in Jacob's adoption of Ephraim and Manasseh in That there were 12 tribes seems to have become unchangeable at an early stage of Israel's history, perhaps because of the number of lunar months in a year. Levi had originally been a tribe like any other with its own tribal land, but then Levi became essentially landless, a scattered people of priests and religious functionaries, with only a few cities of their own. To compensate for its absence, the Israelites counted the territory elsewhere attributed to Joseph as two territories, each with its own ancestor figure. And thus the tribal list in could omit the Levites and, by replacing Joseph with Ephraim and Manasseh, still include the names of 12 tribes.

The descent engine was used again two hours after pericynthion, the closest approach to the Moon ("PC+2 burn"), to speed the return to Earth by 10 hours and move the landing spot from the Indian Ocean to the Pacific Ocean. A more aggressive burn could have been performed at PC+2 by first jettisoning the service module, returning the crew in about the same amount of time as a direct abort,p. III-20 but this plan was rejected since it would require leaving the command module's heat shield exposed to the extreme temperatures of space, it would virtually deplete the DPS's propellant supply (leaving nothing for midcourse correction burns), and it would result in Apollo 13 landing in the Atlantic Ocean where the US Navy had no recovery ships placed. The 4-minute 24-second burn was so accurate that only two more small course corrections were subsequently needed before Earth reentry.

The full report as submitted to Congress came under criticism from several people at NASA, noting that, although the cameras lacked redundancy, any one of dozens of failure modes in the booster or spacecraft could also result in failure to return any TV images. In regards to the lack of adequate prelaunch testing, they brought up the incident back in 1961 with Ranger 1 deploying its solar panels during a ground test and that ground tests with full 60 W power had been discontinued on the Block II probes for fear of accidentally igniting the midcourse correction engine on the pad and destroying the entire launch vehicle in the process. RCA also promised to look into workmanship standards at their main plant in Hightstown, New Jersey, when examination of a sealed Ranger module discovered a plastic bag with screws and washers inside. Although there was suspicion that this had been done by a disgruntled employee, it was far more probable that someone had done it by accident.

RAF Fylingdales, UK and Clear Air Force Station, Alaska BMEWS stations became SSPARS radar stations when their respective AN/FPS-126 radar (3 faces) and 2001 Raytheon AN/FPS-120 Solid State Phased Array Radar became operational. In 2007, 100 owners/trustees of amateur radio repeaters in the 420 to 450 MHz band near AN/FPS-123 radars were notified to lower their power output to mitigate interference, and AN/FPS-123s were part of the Air Force Space Surveillance System by 2009. The Beale AN/FPS-123 was upgraded to a Raytheon AN/FPS-132 Upgraded Early Warning Radar (UEWR), circa 2012, with capabilities to operate in the Ground-based Midcourse Defense (GMD) ABM system—the Beale UEWR included Avionics, Transmit-Receive modules, Receiver Exciter / Test Target Generator, Beam Steering Generator, Signal Processor, and other changes. After additional UEWR installations for GMD at Thule Site J and the UK (contracted 2003), a 2012 ESD/XRX Request for Information for replacement, and remote operation, of the remaining "PAVE PAWS/BMEWS/PARCS systems" at Cape Cod, Alaska, and North Dakota was issued.

The XBQM-108 project was initiated in 1975 by the Aviation and Surface Effects Department of the U.S. Navy's David W. Taylor Naval Ship Research and Development Center.Eilertson 1977 The project was intended to demonstrate the practicality of the 'Vertical Attitude Take-Off and Landing' (VATOL), or 'tailsitter' flight profile for remotely piloted vehicles, as the Navy believed the increasing threat posed by cruise missiles required that aviation assets be dispersed among additional ships of the fleet, which would possess limited space for aviation operations as opposed to conventional aircraft carriers. Based on the MQM-74 Chukar target drone, the XBQM-108A was modified with a revised, delta wing with canard control surfaces. The XBQM-108A was fitted with a thrust vectoring system based on the use of vanes that deflected the engine's exhaust; the aircraft retained the Chukar's recovery parachute and radio guidance system,Parsch 2002 with the addition of a radar altimeter and midcourse guidance unit based on that of the AGM-84 Harpoon anti-ship missile.

Twenty-six of 35 aboard were rescued. Ehime Maru had been on a fishing and research mission when Greeneville rapidly surfaced and collided with her stern. At the time of the accident the was conducting an "emergency ballast tank blow," a procedure used to bring subs to the surface in the event of an emergency. In this case it was used for training, on a one-day cruise with 16 military and civilian guests. On 25 January 2002 the Missile Defense Agency and the Navy conducted a successful flight test in the continuing development of a Sea- Based Midcourse (SMD) Ballistic Missile Defense System (BMDS). Flight Mission-2 (FM-2) involved the launch of a developmental Standard Missile 3 (SM-3) and kinetic warhead (KW) interceptor from Lake Erie and an Aries target missile launched from the Pacific Missile Range Facility (PMRF) on the island of Kauai, Hawaii. The target was launched at 18:00 (EST) 26 January. About eight minutes later, Lake Erie, equipped with Aegis Lightweight Exo- atmospheric Projectile (LEAP) computer programs and equipment, and having tracked the target with the Aegis SPY-1 radar and developed a fire-control solution, launched the newly developed SM-3.

Luna 23 was a Soviet Moon lander mission which was intended to return a lunar sample to Earth. Launched to the Moon by a Proton-K/D, the spacecraft tipped over on its side and was damaged upon landing in Mare Crisium (Sea of Crises). The sample collecting apparatus could not operate and no samples were returned. The lander continued transmissions for three days after landing. In 1976, Luna 24 landed several hundred meters away and successfully returned samples. The asteroid-like object 2010 KQ is believed to be a rocket that parted the Luna 23 module after launch.Man-made object spotted with FTN , Edward Gomez, May 26, 2010 Luna 23 was the first modified lunar sample return spacecraft, designed to return a deep core sample of the Moon's surface (hence the change in index from Ye-8-5 to Ye-8-5M). While Luna 16 and Luna 20 had returned samples from a depth of 0.3 meters, the new spacecraft was designed to dig to 2.5 meters. After a midcourse correction on 31 October, Luna 23 entered orbit around the Moon on 2 November 1974.
