Villa-Lobos was the last name of an astronaut who was part of ISS Expedition 42 prior to or during the events of Gravity.
Villa-Lobos is never mentioned nor seen in Gravity, and his name is only derived from a mission patch on L. Demidov's space suit. He was a member of ISS Expedition 42, and therefore was on board the station for some time. Whether he was on board the ISS or left the station prior to the events of Gravity is unknown.
- "Villa-Lobos" is probably a reference to the late Brazilian composer and guitarist Heitor Villa-Lobos.
