Samantha Carter is an astrophysicist, engineer and pilot as well as a member of the United States Air Force who played a key role in establishing the Stargate Program before being assigned to the SGC'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/General Jack O'Neill once emphatically proclaimed her brain to be a national resource.
DID YOU KNOW: During her off hours, Sam likes to work on her motorcycle.
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, after returning to Earth, Carter was later made the commander of the Daedalus-class ship, George Hammond which was originally called the Phoenix with the ship itself later being renamed the George Hammond in honor of the former Commander of the Stargate program, George S. Hammond, who died in 2008after suffering a heart attack.
