This week's excitement was disappointing when NASA announced it would have to mixwhich would scrub the first all-female spacewalk in history. The reason: Punctually to the Friday event were not enough medium-sized space suit torsos available.
NASA astronaut Anne McClain, who made her first spacewalk at the International Space Station on March 22, spoke in defense of Wednesday's decision based on her recommendation.
"Managers need to talk hard and I am fortunate enough to work with a team that trusts my judgment, and we must never accept a risk that can be mitigated instead," McClain tweeted. "Crew safety and mission execution are paramount."
NASA astronauts Christina Koch and McClain were originally scheduled to go together in the vacuum of space to continue their work a project to upgrade the batteries for the station's solar power system. Now Koch and NASA boss Nick Hague are scheduled to work outside the ISS on Friday.
McClain called for her first spacewalk when she decided that she would rather be comfortable in a medium suit than a big suit. It takes time to properly prepare a spacesuit and only a medium suit was ready for use, so Koch will wear it on Friday.
A third spacewalk scheduled for April 8 is tentatively scheduled for McClain and Canadian Space Agency astronaut David Saint-Jacques.
McClain had another tweeted message for people upset about adapting to the spacewalk: "Tune in – history is written here daily!"
