All of the original members of SG-1 have now left the SGC, and Lt. Col. Cameron Mitchell has now been given command of an empty SG-1, as a reward for the work he did in the battle over Antarctica (Episode 7x22). Mitchell tries in vain to get the original members of SG-1 back together, but none of the team seems to want to. That is until Vala Mal Doran, an old 'friend' of Daniel's, comes through the gate with an interesting proposition. This leads the slightly smaller original SG-1 team, with Mitchell, in a new direction, away from the Goa'uld, and in search of more knowledge of the Ancients.
Season 9 Episode 1 of Stargate SG-1 resulted in a 0.00 rating in the 18-49 demographic.

    Step through the Stargate with SG-1, a team of soldiers and scientists, as they travel instantaneously to other planets to explore, forge alliances, defuse crises, establish trade, investigate ancient mysteries and defend Earth from such hostile forces as the Goa'uld and the Replicators.
For eight years, from their base at the U.S. Air Force's Stargate Command in the Rocky Mountains, Colonel Jack O'Neill, Dr. Daniel Jackson, Lt. Colonel Samantha Carter and alien warrior Teal'c have braved everything that the universe has thrown at them, from interstellar war and evil twins to passing and ascension.
But changes came to SG-1 as it began its ninth year of fearless service to Earth. New faces joined the team, as Lt. Col. Cameron Mitchell tries to fill the very big shoes of former SG-1 leader O'Neill, while General Hank Landry must adapt to the unique challenges of running Stargate Command, a posting unlike any other the military has to offer.
Offworld, SG-1 might have new friends - or new foes - in Vala, a former Goa'uld host turned freedom-fighter; and Gerak, a Jaffa leader who vies with Teal'c for political control of the new Jaffa nation.
