Astronaut Barry Wilmore on the
First of Three Spacewalks
NASA
astronaut Barry Wilmore works outside the International Space Station on the
first of three spacewalks preparing the station for future arrivals by U.S.
commercial crew spacecraft, Saturday, Feb. 21, 2015. Fellow spacewalker Terry
Virts, seen reflected in the visor, shared this photograph on social media.
The
spacewalks are designed to lay cables along the forward end of the U.S. segment
to bring power and communication to two International Docking Adapters slated
to arrive later this year. The new docking ports will welcome U.S. commercial
spacecraft launching from Florida beginning in 2017, permitting the standard
station crew size to grow from six to seven and potentially double the amount
of crew time devoted to research.
The
second and third spacewalks are planned for Wednesday, Feb. 25 and Sunday,
March 1, with Wilmore and Virts participating in all three. NASA
