Samantha Carter is an astrophysicist, engineer, and pilot as well as a Colonel in the United States Air Force who played a key role in establishing the Stargate Program before being assigned to Stargate Command's flagship team, SG-1 where she was the second-in-command for eight years before becoming the commanding officer of SG-1 for a year. Considered Earth's leading expert on the Stargate and a host of other alien technology, her former commanding officer, Colonel Jack O'Neill once emphatically proclaimed her brain to be a national resource.
After serving on SG-1 for ten years during that time which she saved her own life and those of her colleagues during various missions as a member of SG-1, the SGC and as a member of the United States Air Force, Carter was eventually reassigned to the Atlantis expedition which she led for over a year before being replaced by Richard Woolsey.
In 2009, Carter was later made the commander of the Daedalus-class ship, George Hammond which was named in honor of the former Commander of the Stargate Program, Lt. General George S. Hammond, who died in 2008 after suffering a heart attack.
