When the Goa'uld destroy the Antarctic Stargate, SG-1 is rerouted to Russia, as the Russians had retrieved the Achilles Stargate from the ocean floor. Teal'c arrives at the facility as well, seeking to use the Stargate to reach the time machine before Qetesh. The two sides agree to a truce and get to Ba'al's time machine: an underground supercomputer connected to hundreds of satellites that monitor solar flares from various stars that could intersect a wormhole created by the Stargate; the flares are necessary for time travel.
When the Goa'uld annihilate the Antarctic Stargate, SG-1 is redirected to Russia, as the Russians had recovered the Achilles Stargate from the ocean floor. Teal'c arrives at the facility as well, seeking to utilize the Stargate to reach the time machine before Qetesh. The two sides agree on a truce and converge on Ba'al's time machine: an underground supercomputer linked to hundreds of satellites that monitor solar flares from various stars that could intersect a wormhole created by the Stargate; the flares are essential for time travel.
