Factual error: A round-trip voyage between Mars and Earth would take about two years. Although the movie's timeline is compressed, from when the astronauts supposedly leave Earth to them supposedly returning (and dying) and then Caulfield rescuing Brubaker, the entire plot implausibly takes place in only eight months. It is mentioned at the memorial that they "left" Earth eight months earlier. The military memorial is held at least a month after the "tragedy" so that would mean they made the trip in seven months, which is impossible. The film is not set in the future when technology would be more advanced.
