The imagined possibility of getting between Hubble and ISS, despite their different orbits, is one of those scientific sacrifices to story in a film that, in Grazier's mind, has otherwise done its homework. Judging by the overall positive reaction to the film, that imaginative leap is more than justified for most viewers of the film. But the problem hasn't gone unnoticed: the New York Times also honed in on the "plot hole" of vastly different orbits between origin and destination for the stranded characters in the film. Tyson noticed the problem too — not only is travel between the two impossible, but the film also depicts them as in sight lines of each other. Here are some other errors Tyson spotted:

Gravity entered the box office at kind of an awkward time for some space lovers. NASA, which celebrated its 55th anniversary on Tuesday, is all but completely closed for business during the government shutdown (its latest Mars mission, however, will go ahead as scheduled). The shutdown has hit the agency especially hard, too.
