Sat1

Sat1 was the callsign of an astronaut assigned to the International Space Station.

Biography
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 Cpt. Price's ICBM from Sat1's Helmet-Cam.

Sat1 was later killed as the ICBM blast over Washington, D.C. destroyed the satellite. The player's viewpoint reverts to Ramirez's.
