The crew started their fourth day in space at 2:02 a.m., after being awakened by the Chumbawamba song “Tubthumping.” It was played for Mission Specialist Sandy Magnus.
Magnus, along with Pilot Doug Hurley, will be at the controls of the space station’s robotic arm beginning at 4:09 a.m. to remove the Raffaello module from the shuttle’s cargo bay. They’ll install it on the station’s Harmony node 30 minutes later.
Once that is complete, Magnus will work with Commander Chris Ferguson to prepare the module’s hatch for opening at 12:39 p.m., after which the crew will begin unloading the 9,402 pounds of supplies it carried into space.
In addition, Ferguson and Mission Specialist Rex Walheim will begin moving another 2,281 pounds of cargo brought up on Atlantis’ middeck over to the space station. And later in the day, the entire shuttle crew will come together with station Flight Engineers Ron Garan, Satoshi Furukawa and Mike Fossum to review the procedures for the mission’s spacewalk. Fossum and Garan will perform that spacewalk on Tuesday.
Meanwhile, here on the ground, flight controllers were able to verify that the track of a piece of orbital debris they began watching on Saturday will not be a threat to the shuttle and station. No adjustments to the shuttle and station’s orbit will be necessary to avoid the debris, which is part of satellite COSMOS 375 and one of more than 500,000 pieces of debris tracked in Earth’s orbit.
