Moebius: Part 1

SG1 is anxious to get a ride on the new ship. However, the mood is somewhat darkened by a phone call informing Dr. Jackson of Catherine Langford's death. Daniel receives some of her belongings. Upon delivery it is discovered that almost her entire collection was shipped to Daniel's lab. He finds a possible location of a ZPM, but scans of the area showed that it was no longer there. Daniel proposes that they use the Ancient's time machine to take it from Ra at Giza in 3000 BC. (imdb.com)
