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 and will preview the third in an upcoming news conference on NASA Television and the agencys website.
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 stations 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.
Experts will discuss the work to be performed on the April 8 spacewalk during a news conference at 2 p.m. EDT Tuesday, April 2, at NASAs Johnson Space Center in Houston. Live coverage of the briefing and spacewalks will air on NASA Television and the agencys website.
