I was unable to sit through the whole movie due to the abundance of technical errors. For many years I've been a vicarious astronaut so I'm well-versed in what happens on the ISS, the shuttle (RIP) and other missions. The movie shows Clooney zipping around the space station on his MMU (Manned Maneuvering Unit)which would never happen due to safety concerns, losing control and injuring yourself or damaging the space station.

The other flaw that bugged me was showing the astronauts flailing about at the end of the 100 +/- foot long tether. At no time has NASA ever used such long tethers for the obvious reason of becoming entangled around exterior protrusions like antennae.

Since I wasn't able to sit through the entire movie I don't know about other technical inaccuracies, but it's a safe bet there are plenty!
