Space science encompasses all of the scientific disciplines involved in space exploration and studying phenomena occurring in outer space, such as space medicine and astrobiology.
The following outline is an overview of and topical guide to space science:
Astronomy
Fields of astronomy defined by approach
Observational astronomy – Observatories on the ground as well as space observatories take measurements of celestial entities and phenomena
Astrometry – studies the position and movements of celestial objects
Amateur astronomy
Theoretical astronomy – mathematical modelling of celestial entities and phenomena
Fields of astronomy defined by scope
Astrophysics – study of the physics of the universe; of extraterrestrial objects and interstitial spaces
Space plasma physics
Orbital mechanics or astrodynamics, which also has applications to spacecraft
Stellar astronomy – the study of stars
Solar astronomy – the study of our Sun
Planetary science – the study of planets, especially those other than Earth
Planetary geology
Galactic astronomy – the study of our Milky Way galaxy
Extragalactic astronomy – the study of the larger universe beyond the Milky Way
Physical cosmology – the study of the universe as a whole
Aerospace engineering
Astronautics
Aeronautics
Astrobiology
Astrochemistry or cosmochemistry
Planetary science – overlaps with Earth science
Micro-g environment research
Forensic astronomy
Space archaeology – the study of human artifacts in outer space
Space medicine
Space architecture
Archaeoastronomy – the history of human understanding of the universe
