## ISS Success

It wasn't the spacewalk that was planned, but it was a success nonetheless.

On Friday, NASA astronauts Nick Hague and Christina Koch left the relative safety of the International Space Station's (ISS) interior to embark on a nearly seven-hour-long [spacewalk](<https://blogs.nasa.gov/spacestation/2019/03/29/nasa-astronauts-complete-215th-spacewalk-at-station/>) that wrapped up at 2:27 p.m. EDT.

## Substitute Spacewalker

Astronaut Anne McClain was originally supposed to join Koch on this ISS spacewalk, which would have made it the first to feature [only female astronauts](<https://futurism.com/the-byte/nasa-worlds-first-all-female-spacewalk>).

A last-minute [equipment issue](<https://futurism.com/the-byte/nasa-cancels-first-all-female-spacewalk>) led to Hague filling in for his colleague, but Koch's participation in the walk is still worth celebrating — she's now just the fourteenth woman to take part in a spacewalk.

## Battery Swap

During the spacewalk — ISS's 215th to date — the duo replaced the six nickel-hydrogen batteries that previously powered one pair of the ISS's solar arrays with three more powerful lithium-ion batteries.

They also completed several other tasks designed to facilitate future upgrades, according to a [NASA news release](<https://blogs.nasa.gov/spacestation/2019/03/29/nasa-astronauts-complete-215th-spacewalk-at-station/>).
