The article for me pointed out just how unlikely the entire movie is. I already knew there were a lot of impossibilities in Gravity (changing orbital planes etc) - but reading just how much work it takes to keep two orbiters aligned, and how much work it is to get into and out of a spacesuit. In the movie she gets out of one space suit and then into another, and then out of it again. That right there is impossible from the reading.

The girl made it home (despite being like the worst astronaut ever) so it still counts as a happy ending.
