Crew Notified of Mission Extension

At 6 p.m. EST, International Space Station Capcom Stan Love notified station Commander Scott Kelly and Discovery Commander Steve Lindsey that the “plus one” day is approved – a mission extension day – primarily for outfitting the Permanent Multipurpose Module. They still are awaiting a formal decision on a Soyuz fly around which will be made Tuesday at the space station Mission Management Team meeting.

First Spacewalk of STS-133 Mission Complete

Spacewalkers Steve Bowen and Alvin Drew completed a six-hour, 34-minute spacewalk at 5:20 p.m. EST.

This was the first of two STS-133 spacewalks, the 243rd by U.S. astronauts, the sixth for Bowen, totaling 41 hours and four minutes, and the first for Drew. It was the 154th spacewalk in support of International Space Station assembly and maintenance, totaling 967 hours, 39 minutes.

Today’s Mission Status Briefing is scheduled for 8 p.m. EST. It will air on NASA Television

Spacewalkers Extend Station’s Mobile Transporter Track

Spacewalkers Steve Bowen and Alvin Drew added two extensions to the station’s mobile transporter track, which will allow the transporter to travel the entire track length with the Crew Equipment Translation Aid cart and reach all of the worksites. They also opened and filled a metal cylinder with the vacuum of space, part of a Japan Aerospace Exploration Agency activity called “Message in a Bottle.” The bottle will be returned to Earth for public display.

Spacewalkers Attach Ammonia Pump Module

Assisted by space station robotic arm drivers Scott Kelly and Mike Barratt, spacewalkers Steve Bowen and Alvin Drew attached an 800-pound ammonia pump module to External Stowage Platform 2 on the outside of the Quest airlock. The failed pump module will remain there until it can be brought back to Earth for engineering analysis at a future date. The spacewalkers also installed a tool to safely vent the remaining ammonia from the pump module into space.

The pump module failed in July 2010 and was removed from its original truss location during an Aug. 11, 2010, spacewalk by Doug Wheelock and Tracy Caldwell-Dyson. It had been temporarily stored on the mobile base system payload orbital replacement unit accommodation (POA) for about 6.5 months.

Kelly, Barratt Relocate to Continue Spacewalk Support

The Robotic Work Station in the International Space Station's Cupola has shut down, temporarily halting the work of station robotic arm operators Scott Kelly and Mike Barratt. Rather than spending up to 30 minutes to "reboot" the system in the Cupola, Kelly and Barratt are relocating to another Robotic Work Station in the Destiny Laboratory to continue their support of the spacewalk.

Bowen, Drew Install Power Cable

Spacewalkers Steve Bowen and Alvin Drew completed their first task, installing an extension to the J612 power cable. Without the extension, the cable would have been inaccessible after the Permanent Multipurpose Module is installed to the International Space Station on Tuesday. The cable is connected from the Unity node to the Quest Airlock to provide a backup power capability to the Tranquility node, should it ever be needed.

Alvin Drew is the 200th human to perform a spacewalk, his first. This is Steve Bowen’s sixth spacewalk. The first STS-133 spacewalk began at 10:46 a.m. EST.

This is the 154th spacewalk supporting assembly and maintenance of the space station and the 234th excursion conducted by U.S. astronauts.

Bowen, Drew Conducting First STS-133 Spacewalk

Alvin Drew is the 200th human to perform a spacewalk, his first. This is Steve Bowen’s sixth spacewalk. The first STS-133 spacewalk began at 10:46 a.m. EST.

Bowen, EV-1, is the lead spacewalker and is wearing a suit with red stripes, while Drew, EV-2, wears an all-white spacesuit. Bowen’s helmet camera displays the number 19 and Drew’s the number 20.

Bowen and Drew will install the J612 power extension cable in preparation for Tuesday’s attachment of the Permanent Multipurpose Module to the Unity node. Next, they will move an 800 pound failed pump module to External Stowage Platform 2 on the outside of the Quest airlock, where it will remain until it can be returned to Earth at a future time. They will install a camera wedge on the right hand truss segment to give the camera added clearance now that Express Logistics Carrier-4 is attached to the station. After that, they will move further down the right hand truss to the solar alpha rotary joint where they will affix two extensions to the station’s mobile transporter track, which will allow the transporter to travel the entire track length with the Crew Equipment Translation Aid cart and still reach all of the many worksites. They also will open and fill a metal cylinder with the vacuum of space, part of a Japan Aerospace Exploration Agency activity called “Message in a Bottle.” The bottle will be returned to Earth for public display.

Discovery Mission Specialist Nicole Stott is inside the International Space Station, choreographing the activities and coordinating communications between the spacewalkers and Mission Control in Houston. Station Commander Scott Kelly and Discovery Mission Specialist Mike Barratt will operate the station’s 58-foot long robotic arm to maneuver the pump module and other hardware during the spacewalk.

This is the 154th spacewalk supporting assembly and maintenance of the space station and the 234th excursion conducted by U.S. astronauts.
