Extraterrestrial

Extraterrestrial refers to anything that originates or exists outside of the Earth's atmosphere. In the context of space and astronautical engineering, extraterrestrial often refers to the study and exploration of celestial bodies such as planets, moons, asteroids, and comets. This includes the development of spacecraft and technologies that enable humans to travel to and explore these extraterrestrial destinations. Extraterrestrial research also encompasses the search for life beyond Earth, including the study of exoplanets and the potential for habitable environments. The study of extraterrestrial phenomena such as cosmic rays, solar wind, and space weather also falls under the umbrella of extraterrestrial research.
