Sat1 was the callsign of an astronaut assigned to the International Space Station.
Sat1 was conducting extra-vehicular activities when he was contacted by NASA to observe the ICBM launched by Cpt. Price. Sat1 witnessed the missile's detonation, as well as the destruction of the ISS. Sat1 was subsequently thrown through space due to the missile's explosion before being hit by one of the ISS' solar panels.
Sat1 is one of two playable characters in "Second Sun". After the helicopter whites out Pvt. James Ramirez's line of view while holed up in the downed chopper, the view shifts to Sat1 who is instructed to look at the Eastern (dark) side of the Earth so that Houston Command can get footage of the ICBM Captain Price from Sat1's Helmet-Cam.
- In Call of Duty: Modern Warfare 2's PC files, there is some unused dialog for the scrapped mission set in the ISS. An unknown character contacts the player calling him 'Jord', Houston also refers to him as Davies.
- Sat1's arm bears a wrist-mounted computer that has the time: 20:09 (the year Modern Warfare 2 was released), an image of a crescent moon and a message that reads "come home soon".
