Spacewalk Underway to Move Mobile Transporter Rail Car

Station Managers “GO” For Monday Morning Spacewalk
“The International Space Station Mission Management Team met Sunday and gave its approval to proceed with a spacewalk Monday out of the Quest airlock by Expedition 46 Commander Scott Kelly and Flight Engineer Tim Kopra of NASA to assist in moving the Mobile Transporter rail car a few inches to a worksite on the station’s truss where it can be latched in place and electrically mated to the complex. The green light for the unplanned spacewalk to take place Monday came three days after the Mobile Transporter stalled just four inches away from its embarkation point at worksite 4 near the center of the station’s truss as it began to move to another worksite to support robotic payload operations with its attached Canadarm2 robotic arm and the Special Purpose Dexterous Manipulator (Dextre).”
Marc’s note: Watch it live.
Marc’s update: The mobile transporter rail car was successfully moved and is in place for the Progress 62 cargo resupply spacecraft arrival scheduled for Wednesday.
