Data accumulation from the closer celestial bodies resulted in development of parallel branches such as selenology, areology, etc.

Heliology and selenology were subjects which he studied with special interest, and on which he speculated with ingenuity as well as learning.

In technical terminology, the word-stems seleno- (from Greek selēnē "moon") and cynthi- (from Cynthia, an epithet of the goddess Artemis) are sometimes used to refer to the Moon, as in selenography, selenology, and pericynthion.

Today, selenography is considered to be a subdiscipline of selenology, which itself is most often referred to as simply "lunar science." The word selenography is derived from the Greek lunar deity Σελήνη Selene and γράφω graphō, "I write".

With or without VSE, human spaceflight will be made sustainable. However, without VSE, more funds could be directed toward reducing human spaceflight costs sufficiently for the betterment of low Earth orbit research, business, and tourism. Alternatively, VSE could afford advances in other scientific research (astronomy, selenology), in-situ lunar business industries, and lunar-space tourism. The VSE budget required termination the Space Shuttle by 2010 and of any US role in the International Space Station by 2017.

He was generally regarded as one of the world's foremost geologists, and probably the leader in the field of economic geology (the application of geology to mining). At the age of 68 he became interested in the origin of craters of the moon, and published four books that made a major contribution to the field. His last book, "Geology as applied to Selenology", published just a year before his death, has been criticised, but was influential in the new field. He was considered a superb and pithy writer.

Surface of Mars as photographed by the Viking 2 lander December 9, 1977 With the advent of space exploration in the twentieth century, geologists have begun to look at other planetary bodies in the same ways that have been developed to study the Earth. This new field of study is called planetary geology (sometimes known as astrogeology) and relies on known geologic principles to study other bodies of the solar system. Although the Greek- language-origin prefix geo refers to Earth, "geology" is often used in conjunction with the names of other planetary bodies when describing their composition and internal processes: examples are "the geology of Mars" and "Lunar geology". Specialised terms such as selenology (studies of the Moon), areology (of Mars), etc.
