Space Station Live: Go for EVA 31 NASA

NASA Commentator Pat Ryan talks with Alex Kanelakos, the Increment 42 Lead EVA Officer, about preparations for a spacewalk this Sunday, March 1, by International Space Station Commander Barry Wilmore and Flight Engineer Terry Virts. The station’s Mission Management Team gave unanimous approval for this third spacewalk in nine days after hearing discussion of all the technical preparations, including analysis of the small amount of water found inside Virts’ helmet at the end of the previous EVA. The astronauts will lay out cable and antennae for a new rendezvous and navigation system to support dockings to the station by future visiting vehicles, including the new U.S. commercial crew vehicles.
