The plans for NASA over the next spacewalk are changed.
The March 29 mission was supposed to be the first female spacewalk, but there are not enough of the correct-sized space suits ready in time for Friday, so it will be performed by a man and a woman instead of a NASA press release said Monday.
Anne McClain and Christina Koch, two NASA astronauts with the Expedition, 59, had been scheduled for the operation of the spacewalk, but mission managers decided to switch so that Koch and NASA astronaut Nick Hague could operate the command.
The hague and McClain operated the first spacewalk in a series of three on 22 March.

They started the installation of lithium-ion batteries, a few solar panels on the International space station, according to the release.
While McClain was on the job — that was also her first spacewalk — they found that the best fitting “shirt” of the space was the small and medium sized enterprises.
However, there is only one medium-sized hard upper torso on the space station that will be ready in time for Friday spacewalk, so Koch will wear, the release said.
It will be Koch’s first spacewalk. They Hague completing the installation of the battery.

Now McClain will perform her second spacewalk on 8 April for the third of the series.
McClain will be joined by the Canadian Space Agency astronaut David Saint-Jacques, although the assignments to be completed after Friday’s spacewalk completed.
Initially, Hague and Saint-Jacques were scheduled to perform on April 8, spacewalk together.
Spacewalks, also called extravehicular activity (EVA), usually last between five and eight hours and are carried out, so that astronauts can make repairs to the equipment, or performing experiments. Each of the upcoming spacewalks on 29 March and 8 April are expected to be about six and a half hours, depending on the release.
