Watch live: Astronauts conduct emergency spacewalk to replace computer system

ASA astronauts Peggy Whitson and Jack Fischer are preparing for an emergency spacewalk to replace a fried data relay box.

“The spacewalkers are gathering their tools and checking their spacesuits today with assistance from Flight Engineer Thomas Pesquet,” NASA officials explained in a blog update. “The trio are also reviewing the contingency spacewalk procedures.”

The computer system, which is vital to an array of space station components, is known as the Multiplexer-Demultiplexer. It failed on Saturday morning.

“The MDM controls the functionality of station components such as the solar arrays, radiators, cooling loops and other systems,” NASA said.
