NASA Astronauts Complete Spacewalk

NASA astronauts Steve Swanson and Rick Mastracchio completed a 1.5-hour spacewalk on Wednesday to replace a failed Multiplexer/Demultiplexer (MDM) back up computer aboard the International Space Station.

The spacewalk started just before 10 a.m. ET when the crew switched their suits to battery power, signaling the start of the operation. They began their re-pressurization sequence in the ISS's airlock at 11:32 a.m. ET, which signifies the excursion’s end time.
