Live in Orbit: Kopra recharges oxygen, JEF moved

Just over three hours into the spacewalk, Tim Kopra re-entered the airlock to top off his oxygen tank to allow him to complete the 6.5-hour spacewalk.

Being handed off between robot arms, the Japanese Exposure Facility, an outdoor space lab, is scheduled to be installed at 5:38 p.m. EDT on the Kibo module. The space station robot arm, which relocated while the shuttle arm held the JEF, will grapple the JEF and place it on the Kibo module.

Remaining tasks today include include preparing a docking place for a Japanese H2 transfer vehicle later this year, working on an external equipment cart and fixing a jammed spare parts mount.

Today's spacewalk began at 12:19 p.m. EDT, with the switching of spacesuits to battery power. The pair made up lost time early in the spacewalk.

David Wolf, on his fifth spacewalk, wears red stripes on the legs of his spacesuit. Kopra's has no markings for his first spacewalk, the 126th spacewalk to build the International Space Station.
