ASTEP is one of four elements of NASA's Astrobiology Program, which falls under the Planetary Science Division of the Science Mission Directorate. According to the formal description from NASA, "The ASTEP program sponsors the development of technologies that enable remote searches for, and identification of, life in extreme environments, including planetary surfaces and subsurfaces."
The biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth 's surface, the cooling rate of the planet's interior , gravitational interactions with other objects in the Solar System , and a steady increase in the Sun's luminosity .

Breakthrough Starshot is a research and engineering project by the Breakthrough Initiatives to develop a proof-of-concept fleet of light sail spacecraft named StarChip, [4] to be capable of making the journey to the Alpha Centauri star system 4.37 light-years away. It was founded in 2016 by Yuri Milner, Stephen Hawking, and Mark Zuckerberg. [5] [6]

In planetary science, the term geology is used in its broadest sense, to mean the study of the surface and interior parts of planets and moons, from their core to their magnetosphere. The best-known research topics of planetary geology deal with the planetary bodies in the near vicinity of the Earth: the Moon , and the two neighboring planets ...
The US teams were initially selected from a total of about 200 proposals; however, the coalition is expected to expand nationally and internationally as the project gets underway. [13] Teams will also work with amateur citizen scientists who will have the ability to access the public Kepler data and search for exoplanets.
Theoretical planetologists also use numerical models to understand how the Solar System planets were formed and develop in the future, their thermal evolution, their tectonics, how magnetic fields are formed in planetary interiors, how convection processes work in the cores and mantles of terrestrial planets and in the interiors of gas giants ...
