Space Station Camera

Space Station Chimera was a scientific research space station in the Third Zone, where the scientists Kartz and Reimer conducted time travel experiments. Dastari was the station Head of Projects, and Shockeye of the Quawncing Grig was the chef. The Time Lords sent the Second Doctor to the station to stop the experiments. The station was attacked by Sontarans as part of Dastari's plan to kidnap the Doctor, who had been sent by the Time Lords to investigate the experiments. Almost everyone on the station was killed by the Sontarans.

Upon seeing the station on the TARDIS scanner screen, Jamie McCrimmon was amazed by its size, saying it was "like twenty castles in the sky." (DW: The Two Doctors)

Behind the scenes
In the novelisation of The Two Doctors the station is called "Space Station J7."
