One of the most exciting development in the past several years has been the rapid democratization of space. Whereas during the cold war and its immediate aftermath, access to space was tightly controlled, this hegemonic access to space has been rapidly shifting in recent years (succinctly put here and here).  With technological leaps in miniaturization and industrial changes towards privatization, the ability to view the world from a low earth orbit and place objects there is opening up at a fantastic pace (a low earth orbit is roughly between 100 miles and 1,200 miles; the International Space Station is usually orbiting at around 260 miles.  If you want to look at the earth from space right now you are blessed with a range of options:
