Factual error: Draper consults a recorded video-lecture on survival tips while on Mars. Behind the lecturer is a chalkboard with two force laws from physics written. One is Newton's law of gravity, the other is Coulomb's law for electric charges. The constant of proportionality for Coulomb's law is given as e0, whereas this is really only one component in the whole expression for the constant, 1/e04pi.
Revealing mistake: Early in the film, when Commander Chris Draper is still wearing his space gear on the Martian surface, multiple helmet reflections reveal that at least two and as many as four powerful artificial light sources (in addition to the Sun) were used to illuminate the exterior scenes.Charles Austin Miller
