The Kurios Spaceport Space Station aka Space Station is the location of "Onslaught", which is the first mission in SAS: Zombie Assault 4. It is where players first encounter the zombies infected by the Thera Virus. Not much is actually known about this location. The player is given a half map of the station, but no details are shown except the bay numbers and shape of the station.
It's still unknown if the Space Station was destroyed or not. However, as players have to kill all hostiles to win the game, the Space Station is possibly still there.
