There's more than just football going on this Sunday. The shuttle Endeavour is scheduled to launch very early on Sunday morning, on what will be the first of a final five planned shuttle missions before the shuttle program is retired.
The primary goal of the flight is to attach the new Tranquility module to the left side of the lab complex to house life support gear, exercise equipment, and a robotics workstation. Astronauts plan to conduct three spacewalks before returning to Earth.
According to a Saturday post on NASA's Space Shuttle page, "the rotating service structure was rolled away from Endeavour this morning," and the shuttle is scheduled to lift off at 1:39 a.m. PST on Sunday.
You can watch the footage live on NASATV and read NASA's countdown coverage beginning at 8:30 p.m. Saturday.
