Plans for the first all-female spacewalk in history have been scrapped for lack of a second space suit, the US space agency Nasa says.
Christina Koch and Anne McClain had been scheduled to step outside the International Space Station (ISS) on Friday to install batteries. But it turned out they both needed a medium-size spacesuit and only one was ready for use.
Koch will now exit the ISS with male colleague Nick Hague instead.
She will wear the medium-size suit used by McClain on a spacewalk with Hague last week. The issue relates to the spacesuit’s hard upper torso or “shirt”.
