So that the astronauts on board can breath, of course. :)
so the people can breath
because in outer space there is no oxygen
The rockets that have been used carry their one oxygen for the combustion. Or they use a fuel that dosn't need to ignite. These latter propellants rely only on Newtons second law.
oxygen
None they use carbon monoxide
There is no air, and thus no oxygen, in outer space, so the rocket needs to bring its own oxygen to burn its fuel.
Konstantin Tsiolkovsky proved scientifically that rockets could reach outer space.
my answer is air rockets because birds go in there
rockets go outer space to take people to the moon
rockets go outer space to take people to the moon
Of course. Rockets in general have existed for hundreds of years. Rockets which travel to outer space have existed since the 1950s.
Pretty darn close, the SR71 can go out as far as the outer atmosphere.The limitation is that a jet engine needs oxygen to create the flame to get thrust from the engines, and there isn't any in outer space.Rocket engines are used to travel to outer space,and they carry their own oxygen for combustion, or use solid fuel that also creates its own oxygen.
