The network has ordered 20 episodes of each series, in keeping with the current and previous seasons.
Season Ten will make Stargate SG-1 the longest-running science fiction series in U.S. television history, surpassing the nine years and 202 episodes of The X-Files. The series will air its remarkable 200th episode early in Season Ten.
Brad Wright and Robert C. Cooper will return as executive producers on both series. Wright co-created SG-1 with Jonathan Glassner in 1997. Wright and Cooper then created the spin-off series in 2004, with Wright becoming Atlantis‘s day-to-day showrunner while Cooper stepped into that duty for SG-1.
The network has not yet confirmed which regular cast members from the show will return next season, as contract negotiations are likely still pending. No changes in the regular casts are currently anticipated.
The first half of SG-1‘s ninth season has averaged 2.4 million viewers per week, according to SCI FI. The second half of Season Nine and Season Two will kick off in January on SCI FI.
The network is also expected to renew Friday night companion series Battlestar Galactica for a third season, but has not made that official announcement yet. The series is currently SCI FI’s highest-rated, and is critically acclaimed.
Stargate SG-1 is produced by Double Secret Productions, in association with Metro-Goldwyn-Mayer Inc. and Sony Pictures Television. Stargate Atlantis is produced by Acme Shark, in association with Metro-Goldwyn-Mayer Inc. and Sony Pictures Television.
Next season is expected to enter full production in Vancouver, British Columbia in February 2006, with a summer premiere on SCI FI.
