NASA ISS On-Orbit Status 1 March 2015.

NASA astronauts Terry Virts and Barry Wilmore ended their spacewalk at 12:30 p.m. EST with the repressurization of the Quest airlock.

Virts and Wilmore completed installing 400 feet of cable and several antennas associated with the Common Communications for Visiting Vehicles system known as C2V2. Boeing's Crew Transportation System (CST)-100 and the SpaceX Crew Dragon will use the system in the coming years to rendezvous with the orbital laboratory and deliver crews to the space station. They completed one additional task to retrieve a bag to cover equipment on the outside of the station.

The 5-hour, 38-minute spacewalk was the third for Virts and the fourth for Wilmore. Virts has now spent 19 hours and 2 minutes outside during his three spacewalks. Wilmore now has spent 25 hours and 36 minutes in the void of space during his four excursions.

Crews have now spent a total of 1,171 hours and 29 minutes conducting space station assembly and maintenance during 187 spacewalks.

On-Orbit Status Report

Extravehicular Activity (EVA) 31: Wilmore and Virts accomplished all planned objectives and one get-ahead task within a Phased Elapsed Time (PET) of 5 hours 38 minutes. Cristoforetti and Shkaplerov assisted during suit donning and doffing activities. The Joint Airlock egress took place at 5:52am CST and post EVA hatch closure at 11:27am CST. Objectives accomplished during today's EVA are as follows:
