Why Do Rockets Not 'burn Up' On The Way Up? | Science Questions Although space rockets can go several times the speed of sound, they do get some heating on the way up. it's not that much because they're going fairly slowly while they're near the ground where the air's fairly thick. “objects coming back from space are traveling at many times mach speed — faster than the speed of sound — so to keep from burning up or breaking up they must be protected from the intense heat caused by that friction.”.

How Do Rockets Work In Space Without Oxygen?

How Do Rockets Work In Space Without Oxygen? If it tried to pick up this speed while within the atmosphere, it would indeed burn up, because the air compression would heat it up to similar levels as it would experience during reentry. so, rockets don't start to go this fast until they're far out of the thicker layers of the atmosphere. On their way up, rockets aren't nearly as fast for the same altitude as on the way down. also, on the way up most rockets have sharp nosecones, while on the way down you want a very blunt profile (more drag, more deceleration, less heating for the same velocity loss). This could theoretically be accomplished by bringing large retro rockets along, but this is not feasible as it would entail bringing along the same amount of fuel and boosters used at launch. instead, all spacecraft to date have used atmospheric braking. While the rocket is being launched then its acceleration depends only on the burn rate of its boosters. this statement is false.

While the rocket is being launched then its acceleration depends only on the burn rate of its boosters. this statement is false. Short answer: less fuel usage to get into orbit around the earth. long answer: we know that the air density of the atmosphere decreases upwards. at the start, the rocket needs great energy to overcome air resistance and gravity, so that it attains enough altitude when most of its fuel is used up. However, strictly speaking, rockets don’t launch straight up just to escape gravity; they launch upward to get out of the dense atmosphere, then curve sideways to achieve orbital speed. to stay in orbit around earth, a spacecraft must travel sideways at around 7.8 kilometers per second. The faster the movement and denser the atmosphere, the more heating is created. when reentering earth's atmosphere, a rocket is already moving fast and goes through a progressively denser atmosphere (the air is thicker on the ground than at the top of our atmosphere) which creates a lot of heating. One of the most commonly asked questions about rockets is how they can work in space where there is no air for them to push against. the answer to this question comes from the third law.
