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.
