Continuity mistake: This is a two-for-one. When the astronauts are boarding their shuttles, the gantry for the crew of the Freedom (i.e. Bruce Willis' ship) is adorned with the red triangular mission logo for the "Independence" shuttle (i.e. Ben Affleck's ship). The Freedom logo, worn by the nearby technician, is bluer and more circular. Also, the Independence logo on the gantry wall has "STS-90" written as the mission designation, while the patches for the same logo on the crew uniforms say "STS-98." (01:05:55)

Deliberate mistake: According to the mission patches, both the Independence and Freedom are assigned the mission ID of STS-98 (possibly referencing the film's 1998 release date, and is around where the actual STS numbering was at the time). Two problems with this: First, they are two separate shuttle flights, so each should receive its own mission number. Second, STS was the coding for NASA's civilian shuttle. The shuttles in the film are Air Force vehicles and would probably not receive STS designations.

Other mistake: Adding on to the idea of the shuttles flying too close together, at a couple points the ejected shuttles from one booster appear to fly directly into the flight path of the tailing shuttle. While is certainly possible the second shuttle could maneuver to avoid the collision, it further demonstrates the absurdities of launching the two craft in such close proximity.

Factual error: During the opening shot of the shuttle Atlantis in the satellite repair scenes, its cargo bay doors are closed. Standard procedure for orbiting shuttles was to keep its cargo doors open, for a variety of reasons, not the least of which is that the airlock is located within the cargo bay. The astronaut isn't tethered but using an MMU, but still would have to enter and exit through the cargo bay airlock, meaning if the doors where closed, if there were an emergency he'd have to wait for someone to open them before he could get back in.
