Mission specialists Heide Stefanyshyn-Piper, KD5TVR, and Steve Bowen completed the third spacewalk of the STS-126 mission at 7:58 p.m. EST Saturday. The excursion lasted six hours and 57 minutes.

Inside the station, the rest of the shuttle and station crew members transferred supplies and equipment between the two spacecraft.

Bowen and mission specialist Shane Kimbrough, KE5HOD, are slated to perform the mission’s fourth spacewalk Monday. During the spacewalk, the astronauts will focus on the lubrication and servicing of the port solar alpha rotary joint and the replacement of the final trundle bearing assembly.
