How would humanity cope without planet Earth? What are the consequences when people are unwillingly forced to spend their life in outer space? These are two central questions posed by the Swedish science fiction film Aniara (Kågerman & Lilja 2018). The film narrates the experience of the crew and passengers aboard the spaceship Aniara after it is knocked off course on its journey to Mars. Aniara travels further and further into deep space while a growing sense of despair fills the ship. Unable to turn the ship around, the crew and passengers increasingly experience mental illness, which is expressed in terms of anxiety, depression, and suicide. This chapter analyses the film's depictions of mental illness and how these depictions are related to space and time, another central theme of the film. The analysis establishes how the temporality of space is intrinsically connected to the mental states of the characters, specifically, how neither Aniara nor planet Earth can provide a future for humanity. By exploring this connection between space-time and mental illness, it is argued that the film avoids Othering mental illness and, instead, depicts distress, despair, and mental illness as aspects intrinsic to what it is to be human.
