The first in a series of three spacewalks to prepare the International Space Station for future crew vehicles has slipped a day to Saturday, NASA announced Thursday. The spacewalk by NASA astronauts Butch Wilmore and Terry Virts, which was scheduled for Friday, will now take place on Saturday; a second spacewalk, planned for Tuesday, February 24, will also slip to Wednesday. NASA delayed the spacewalks because of extra time needed to confirm their spacesuits are working properly. The spacewalks are designed to prepare the station for the installation of new docking ports that will be used by commercial crew vehicles under development by Boeing and SpaceX. Those docking adapters will be delivered to the station on cargo vehicles later this year.
