Astronautics

Astronautics (alternatively also cosmonautics) is the theory and practice of navigation beyond Earth's atmosphere. The term astronautics was coined by analogy with aeronautics. Because there is a degree of technical overlap between the two fields, the term aerospace is often used to describe both at once.
