Factual error: The shuttle's original mission was to service Hubble, yet when the shuttle is wrecked, Kowalsky moves with Stone to the ISS, which just happens to be "a short hike away." Hubble orbits at an altitude of 350 miles/560km, while the ISS does so at an altitude of about 250 miles/410km. Furthermore, even if they had been able to see the ISS from Hubble's orbit, they would have only seen it speed ahead, as their orbital velocities are very different: 7.66km per second for the ISS and 7.5km per second for Hubble.

Question: On the Russian vessel, shortly after Ryan boards via the airlock, there's a readout in English concerning oxygen. Shouldn't the readout, and indeed virtually everything on that ship, be written in Russian?

Answer: The International Space Station is serviced and manned by representatives from several countries. It stands to reason that because of this, instructions for spacecraft and equipment would be printed in several languages. As the movie shows, in the case of an emergency it would not make sense to have spacecraft and equipment be effectively "locked out" to those who don't speak a particular language when that problem can be easily solved by printing instructions in multiple languages.

This is similar to how the airline industry works internationally. All pilots, crew, air traffickers, etc, regardless of what country, speak in English. It is the international language.
