Leaving the atmosphere is easy for astronauts. All they need is a space capsule to protect them, maintain a safe temperature and provide oxygen. An astronaut's space vehicle starts slowly and gradually increases to ... to maintain orbit around the Earth. Coming back down is much harder because all that speed and energy has to be shed quickly. When the Shuttle drops back into the atmosphere at that high speed ...
... -entry is too steep, the orbiter will overheat and possibly burn up. If the re-entry is too shallow, the orbiter will skip, like a rock on water, off of the atmosphere. Both cases are very bad. An approximate safe entry attitude is 40 degrees above the horizon. This attitude provides a controlled orbiter outside temperature, no chance of skipping, and is assumed ...
