Russians 1st satelite, 1st moon rover, first interplenetary mission, 1st man in space 1st animal in space, 1st woman in space, 1st space station, 1st space walk, first rocket how could america won the race? even the ISS wont be possible if mir wasnt there
If we try to find the boundary of space, we should define it by the altitude and the speed. Because the 1st cosmic speed (28000km/h) needs eligible altitude (about 100-120 km) where the air not dense.
So i think the orbital spaceflight the real spaceflight (like Gagarin's Vostok 1). And why we start the Space Age with the Sputnik 1 and not with the german V2? Because the V2 just flew above 100km but not reach the 1st cosmic speed.
