Historic first all-female spacewalk postponed due to spacesuit availability

With the first in a series of three spacewalks successfully completed at the International Space Station, NASA has updated astronaut assignments for the remaining two spacewalks.

NASA astronauts Nick Hague and Anne McClain conducted the first spacewalk in this series on March 22. Hague and fellow NASA astronaut Christina Koch now are preparing to conduct the second spacewalk Friday, March 29, during which they will continue work started on the first spacewalk to install powerful lithium-ion batteries for one pair of the station’s solar arrays.

Koch had been scheduled to conduct this spacewalk with astronaut McClain, in what would have been the first all-female spacewalk. However, after consulting with McClain and Hague following the first spacewalk, mission managers decided to adjust the assignments, due in part to spacesuit availability on the station. McClain learned during her first spacewalk that a medium-size hard upper torso – essentially the shirt of the spacesuit – fits her best. Because only one medium-size torso can be made ready by Friday, March 29, Koch will wear it.

McClain now is tentatively scheduled to perform her next spacewalk – the third in this series – on Monday, April 8 with Canadian Space Agency astronaut David Saint-Jacques. Assignments for this spacewalk will be finalized following completion of the second spacewalk.

McClain and Saint-Jacques will lay out jumper cables between the Unity module and the S0 truss, at the midpoint of the station’s backbone, during their April 8 spacewalk. This work will establish a redundant path of power to the Canadian-built robotic arm, known as Canadarm2. They also will install cables to provide for more expansive wireless communications coverage outside the orbital complex, as well as for enhanced hardwired computer network capability.

Live coverage of both spacewalks on NASA Television will begin at 6:30 a.m.; and each is expected to last about 6.5 hours. The March 29 spacewalk is scheduled to start at 8:20 a.m., while the April 8 spacewalk is set to start at 8:05 a.m.

These will be the 215th and 216th spacewalks in the history of International Space Station assembly and maintenance. During the first spacewalk of the series, on March 22, McClain became the 13th woman to perform a spacewalk. Koch will become the 14th on March 29.
