... to orbit and to maintain a space orbit. There is a range of speeds at which the different satellites travel. Because of the laws of physics, the faster we travel the higher up in space we are. So if we want to put a satellite in a different orbit, we ...

... . If our re-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 ... 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 as part of the energy/range ...
