You misunderstood. Space rockets carry their own oxygen as the article says. If air were required space shuttles could never return to Earth since there is no air up there, and man could not have gone to the moon (not to mention all the unmanned spacecraft flying out of the solar system).ORIGINAL: pycco

and fusion once started will sustain it self with the power its putting out and still have enough power to power most if not all of other systems. the sub light engines are tricky though as there is no air in space so fuel that we use would not work, so its more of a giant hammer than an engine to give the ship sub light speed
No, rockets do not need air to work (but they do need fuel): as long as you are throwing something out of the back, you move forward.
