NASA astronauts Barry Wilmore and Terry Virts completed the first of three space walks on the 20th of February. Their job was to prep the outpost for the arrivals of commercial spacecrafts carrying astronauts in the near future. The two astronauts ventured out of the station at about 8:00 a.m. EST (1300 GMT). They reentered the orbiting outpost just after 2:30 p.m. EST (1930 GMT), the space walk lasted 6 and a half hours where they spent time installating two international docking adapters that will allow the station to rendezvous with future private space taxis.
