Crew Enters Permanent Multipurpose Module; Prepares for Spacewalk

At 6:17 p.m. EST, International Space Station Commander Scott Kelly became the first crew member to enter the newly-installed Permanent Multipurpose Module (PMM). The PMM was attached to the Earth-facing port of the station’s Unity node earlier in the day and will provide 2,472 cubic feet of pressurized volume for storage and scientific use. Discovery and station astronauts will use their mission extension day to help unload cargo from PMM and dispose of trash in the HTV.

Mission Specialists Steve Bowen and Alvin Drew are preparing for the second spacewalk of the mission by “camping out” in the Quest airlock at 7:48 p.m. The space station crew goes to sleep at 8:53 p.m. and the remainder of the Discovery crew goes to sleep at 9:23 p.m.
