__NOTOC__ 

Astronautics is the science of spaceflight.  It covers the fields of space travel and space exploration. It is divided into a number of subfields covering various aspects of spaceflight.

Aeronautics differs from astronautics in that it is the science of atmospheric flight.  [[Aeronautics on Mars]] can be viewed either as a subset of Spaceflight or as an extension of Earth aeronautics.
