Astronauts Complete Spacewalk; Cargo Transfers Begin

Expedition 28 Flight Engineers Mike Fossum and Ron Garan completed a six-hour, 31-minute spacewalk at 3:53 p.m. EDT Tuesday, retrieving a failed pump module for return to Earth, installing two experiments and repairing a new base for the station’s robotic arm.

Inside the shuttle-station complex, transfer of material from the Raffaello multipurpose logistics module began. The work to unload the more than 9,400 pounds of supplies and equipment brought up by Raffaello and then repack it with 5,700 pounds of equipment, supplies and trash to return home will continue for much of Atlantis stay at the station.

The crew is scheduled to awaken just before 2:30 a.m. Wednesday.
