Astronauts from International Space Station (ISS) Expedition 64 perform a spacewalk on March 13 to continue station upgrades. This was the fifth spacewalk of 2021 and 73rd overall.

Spacewalking astronauts had to take extra safety precautions Saturday after a toxic ammonia exposure from the International Space Station’s external cooling system.

Victor Glover and Mike Hopkins had no trouble removing and venting a couple of old jumper cables to remove any ammonia still lingering in the lines. But so much ammonia spewed out of the first hose that Mission Control worried some of the frozen white flakes might have ended up their suits.

The repairs are expected to take around six and a half hours to complete.
