Space Station Crew Prepare For Emergency Spacewalk

In order for the station to reenter, you'd have to change its orbital velocity by a substantial amount. The interwebs suggests that it's about 150m/s (that's about 300 mph for the metrically challenged).

To change the ISS's velocity that much in a single impact would destroy the entire station. I don't even think the ISS is capable of being deorbited without additional hardware; the Progress supply drones it currently uses to adjust its orbit carry very little thruster fuel. (Just enough to deorbit the Progress itself, plus some spare.)

Personally, the main bit which caused me to roll my eyes is right at the beginning, where the two astronauts admire the sunset, tumbling uncontrollably, while facing in entirely the wrong direction...

was there re-entering on the trailer? isn't the movie about them getting stranded in space. I thought the things burning in atmosphere lower were pieces of some asteroid or something. though I wasn't paying too much attention.
