Takemitsu was the last name of an astronaut who was on board the ISS during or prior to the events of Gravity.
Takemitsu is never seen or mentioned in Gravity, and his name is only derived from close inspection of a mission patch on L. Demidov's suit. Apparently, he was a member of ISS Expedition 42 with four other astronauts. Whether he was on board the ISS during the events of the film or left the station earlier is unknown.
- "Takemitsu" is probably a reference to Japanese composer Tori Takemitsu.
