** Voyager 1 and Voyager 2 reached Io in 1979, around the same time as ''Outland'' was being conceived, but the film did not incorporate any of the new information about the moon's highly unstable volcanic environment.
** The film ignores the very high level of radiation around Io, which was discovered by Pioneer 10 in 1974. (The novelization, though, mentions that station personal wear personal dosimeters which indicate if they've been exposed to harmful levels of radiation in and around the station.)
