Nasa astronauts to carry out first all-female spacewalk

Christina Koch and Anne McClain to make history at International Space Station on 29 March

The first all-female spacewalk is to take place later this month, 35 years after a woman first took part in one.

The US space agency Nasa said astronauts Christina Koch and Anne McClain will walk outside the International Space Station on 29 March on a mission to replace batteries installed last summer.
