Live in Orbit: Spacewalk progressing smoothly

Spacewalkers Dave Wolf and Tim Kopra are moving to other tasks after completing prep work on the Japanese Exposed Facility, a laboratory that will allow experiments in the vacuum of space.

The JEF is scheduled to be installed at 5:38 p.m. EDT, after several handoffs between robot arms.

Remaining tasks today include include preparing 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.

Wolf, on his fifth spacewalk, wears red stripes on the legs of his spacesuit. Kopra's has no markings for his first spacewalk. The astronauts began by working on separate tasks on the 126th spacewalk to build the International Space Station.

The JEF was lifted from Endeavour's cargo bay. The JEF will be handed off several times between robot arms as it makes its way to the Kibo module. The shuttle robot arm will hold the JEF while the station arm relocates itself on the station truss.
