Space   science

Space science – study of everything have  in outer space. This has sometimes been referred as  astronomy, but recently astronomy has come to be regarded as a division of broader space science, which has grown to include other related fields,  such as studying issues associated to space travel and space investigation (including space medicine), space  archaeology  and science performed in outer space .

    Astronomy

        Fields of astronomy  distinct by approach

            Observational astronomy

                    – Observatories on the ground as well as space observatories take capability of celestial entities and phenomena

                Astrometry –

              studies the situation and travels of celestial objects

       Amateur astronomy

                  Theoretical astronomy – mathematical representing of   outer space 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

Space-based radar refers to space-borne radar policy that may have any of a variety of purposes. A number of earth-observing radar and satellites, such as RadarSat, have involved synthetic aperture radar (SAR) to obtain terrain and land-cover in sequence about the Earth.

Space-based radar (SBR) is was  proposed  to constellation of active radar satellites for the United States under the  Department of Defense. The SBR system would allow recognition and tracking of aircraft, ocean-going vessels (similar to the Soviet US-A program), and potentially land vehicles from space. Regarding  information would then be relayed to area and national command centers, as well as E-10 MC2A airborne control posts.
