I can't understand why such a huge popularity when this movie has little to do with the reality. There are many wrongs, let me just count few: -ISS orbits Earth in 45min, so debris at the same orbital hight could not hit it every 90 min. -Hubble telescope and ISS are not on the same altitude and do not have same velocity. Transffering yourself form on position to another takes a space vehicle and advanced planing. -debris traveling at speed of 10 times more than a bullet could not been see. -astronauts can't take off a space suite. They need to spent up to 3 hours in decompression chamber since they breathe pure oxygen at partial pressure, while on ISS there is an air mixture much like on Earth but at a bit lower pressure than on Earth. Also taking a space suite off after decompression is a 3 man job and it take much more than a few seconds and under the suite you wear cooling suite and an adult diaper. -There is no way to operate Chinese space module if you are not familiar with it. -I also doubt that Sandra could be an astronaut since she shows claustrophobia and she makes stupid screams like she's having an intense orgasm. -Chinese station would not fell on Earth by itself. Someone will need to slow down the object to lose altitude and finally enters the Eart's atmosphere. -Durring the atmospheric reentry you feel a strong force of braking, so the object wouldn't just float.
