How does the space station overcome gravity?

Answer 1

Answer #1 .

Rockets were used to put the space station (and its various component parts) into orbit,

thereby overcoming gravity. Once in orbit, gravity continues to be overcome by the

angular momentum of the orbiting station. Sometimes it is necessary to use rockets

again, to add a bit more momentum, since there is still some friction even at that altitude.

==================

Answer #2 .

The parts of the space station certainly needed powerful rocket boosters to raise them

above the atmosphere, and accelerate them to a high enough tangential ('sideways')

speed to maintain orbit. But once that job is done, it doesn't take any more work to

stay in orbit. I mean, look at the Moon !

And actually, for that matter, you would not want the space station to overcome gravity,

because gravity is what keeps things in orbits.
