CAPE CANAVERAL, Fla. — Space station astronauts will venture back out for a spacewalk this weekend, despite a helmet water leak.
On Friday, NASA cleared astronaut Terry Virts' spacesuit for the last of three spacewalks, set for Sunday. Mission managers believe they understand the quirks with this suit, and insist it is safe to use.
A small bit of water leaked into Virts' helmet at the end of Wednesday's spacewalk. NASA says he was never in danger. But engineers spent two days investigating the mishap, given that another astronaut almost drowned when his helmet flooded during a 2013 spacewalk.
Astronaut Butch Wilmore's suit — which is new — functioned perfectly.
Virts and Wilmore are routing hundreds of feet of cable, essential for the arrival of new American-made crew capsules in another couple years.
