Outer space wipeout spaceships speed. Indeed as you realise there is no friction in space. Once the ship is out of the atmosphere there is basically no practical limit to the speed provided you have enough fuel. Space exploration stack exchange is a question and answer site for spacecraft operators scientists engineers and enthusiasts. Why can spaceships only reach outer space by moving upward.
Well there is a tiny bit because space is not 100 empty it has trace amounts of dust hydrogen and radiation. If you accelerate a very small mass of propellant gas to very high velocity the counter force is th. Or to put it more precisely rocket thrust is the reaction force to the action of accelerating propellant. What is the fastest speed ever reached in space travel as measured from the point in space from which it was launched to its currentfinal position.
On spaceships in space. And reach outer space. If yes then how. Rockets push against their own exhaust.
A person cannot travel the speed of light because a propellant to move a space ship in the vacuum of space would have to travel faster than light speed. But this dust will not cause any significant drag unless you move really fast relative to the dust say at a significant fraction of the speed of light. Is it possible to accelerate a spaceship after it has reached outer space.
