Document Summary
Exploration of things in space (planets, moons, asteroid: exploration driven by science, understanding what these bodies are, driven by benefits, exploration is addressing unknowns, driven by ethnics (not in harmful way) Space exploration: doesn"t look at things outside of our own solar system. Space age: oct 4, 1957 with the launch of sputnik (first satellite to orbit earth) Start to feel less atmosphere, less atoms/molecules cause atmos is thinner: once there is no atmos (air) your in space, definition unclear cause atmos doesn"t stop it just thins out. Low earth orbit: 100-2000km from surface of earth, where there are satellites: medium earth orbit: gps satellites, geostationary orbit: bunch of satellites in ring around earth, cyst lunar space: b/w space of earth and moon. Understand the origins of ss: how it forms, how earth forms and where we come from, studies allow us to compare why certain things exist eg. plate tectonics.
