Stargate Atlantis and Stargate SG-1 will both return to Sci Fi Channel, the network announced Monday.
Production on 20-episode seasons of both shows will begin in March, and episodes will debut during the summer.
Stargate SG-1 is returning for a ninth original season, tying Fox’s The X-Files as the longest-running science-fiction drama series on American television, Sci Fi said.
Stargate Atlantis debuted in July.
