In Ad Astra, why don't astronauts fall from space and burn to death?

Because the astronauts fell from the space elevator in Ad Astra instead of the space station, the distance was not enough to generate a powerful high speed and naturally they would not burn. Many people think that everything will burn when it enters the atmosphere, but it is not. Only when it enters the atmosphere at a certain speed will it produce great friction. For example, an astronaut who falls from a space station or a spaceship cannot cross the atmosphere safely. Then, the astronauts in the movie are more like skydiving.

1. In Ad Astra, astronauts just fall off the space elevator, which is equivalent to ordinary skydiving activities.

When watching sci-fi movies, what impressed us most was that everything that entered the earth would burn, but why didn't the astronauts in Ad Astra burn when they fell? Because it's equivalent to skydiving. In fact, people have tried to jump mountains in space, and it has been proved that skydiving in space will not cause high-speed combustion. After all, skydiving in space will not produce great speed, and it will not burn directly through the atmosphere, so it will not be burned.

Second, skydiving in space is equivalent to free fall. Without great speed, it will naturally not cause great friction across the atmosphere.

The reason why Astra astronauts and paratroopers won't be burned after crossing the atmosphere in A.D. is that they didn't produce much speed when falling; In the process of vertical free fall, the spacesuit can cope with the heat generated when passing through the atmosphere, because the slow speed will not cause great resistance to astronauts, nor will it burn like a rescue capsule entering the atmosphere, just like falling from a very high place. On the contrary, if it falls on a space station, spacecraft and other places, it may float into the universe or enter the atmosphere at high speed to burn.

Because it falls vertically, the astronauts in Ad Astra will not be burned.
