From then on, the SGC has explored thousands of worlds, and been responsible for the creation of many alien/human hybrid devices, such as fighter-jets capable of [[hyperspace]] jumps, and powerful new armour.
MuchAbout latera year and a half after the first activation of the Stargate and the mission to Abydos (about half a year after the creation of the SGC and the SG teams), a second Stargate was found on Earth, in [[Antarctica]]. This Stargate was sealed until Season 4, when it was unsealed after the original Giza gate had been crashed into the Pacific Ocean aboard the [[Asgard (Stargate)|Asgard]] vessel [[Beliskner-class Cruiser|''Beliskner'']]. [[Russian Federation|Russia]], performing deep-sea research in the area, discovered the Giza gate and began using it in conjunction with the [[Dial-Home Device|DHD]] they had captured from [[Germany]] after [[World War II]]. Eventually, the Antarctic gate was destroyed by a device controlled by [[Anubis (Stargate)|Anubis]], and the Giza gate was returned to the United States from Russia for rent and an agreement to share plans for the [[F-302]] space fighter-interceptor and [[BC-303]] interstellar battlecruiser.
