While Discovery continues the STS-120 mission on orbit, the next flight is building up a head of steam in preparations for STS-122, with Atlantis now rolling over on November 4.
Atlantis is set to launch to the ISS on December 6, to a station that is undergoing power evaluations, after STS-120’s EVA-2 found a problem with the starboard SARJ (Solar Alpha Rotary Joint) – required to rotate one of the station’s set of solar arrays to track the sun.
