A pair of NASA spacewalkers worked outside the International Space Station on Sunday to finish installing hundreds of feet of cable, four days after water pooled up in the helmet of one of the astronauts at the end of the previous spacewalk.

The water issue sparked concern because a much bigger buildup of water almost drowned a spacewalker in his helmet in 2013 but mission managers said the problem encountered last Wednesday by NASA astronaut Terry Virts was manageable. They said Virts' spacesuit was known to release a small amount of water condensation into the helmet when the suit is repressurized after a spacewalk.

After 2013's scare, astronauts inspected the spacesuits' water cooling systems, and corroded components were replaced. Spacewalkers also wear absorbent pads on the backs of their necks as a safety measure.

The suits' performance is being monitored closely during Sunday's spacewalk. If a problem comes up, the spacewalk would be terminated, and the two astronauts would get back inside the station immediately.

Sunday's operation the last of three orbital outings conducted over the past eight days calls for Virts and fellow NASA astronaut Barry "Butch" Wilmore to install communication antennas and run about 400 feet of cable along the station's main truss over the course of about six hours and 45 minutes.

The wiring job sets the stage for the installation of new docking mechanisms later this year mechanisms that would be used by the commercial spaceships now being developed by Boeing and SpaceX to carry crew, starting as early as 2017. In the meantime, NASA is paying the Russians more than $70 million a seat to transport astronauts to and from the station.

'Cable Guys' Get Set for Spacewalk After Helmet Scare

Leonard Nimoys death on Friday has inspired countless actors, politicians and ordinary people to pay tribute tothe man behind Spock on Star Trek.

Then, on Saturday, American astronaut Terry Virts tweeted this photo while aboard the International Space Station:

The simple Vulcan salute, flashed back at earth from so many miles away, speaks to theimpact that Nimoy and Star Trek had on American space exploration.

Leonard Nimoy was an inspiration to multiple generations of engineers, scientists, astronauts, and other space explorers, NASA Administrator Charles Boldensaid in a statement. As Mr. Spock, he made science and technology important to the story, while never failing to show, by example, that it is the people around us who matter most. NASA was fortunate to have him as a friend and a colleague.

The space agency capitalized on thepublicity generated by the popular series, and Nimoy and other actors in the series became involved with NASA and other scientific organizations. ActressNichelle Nichols, for instance, became a recruiter for the agency, which was seeking more women and minority astronauts. Nichols has said Bolden was inspired to apply for NASA because of her campaign, and Sally Ride heard about the space program first through the Star Trek-linked publicity.

In 1976, NASA unveiled the space shuttle Enterprise, named after the craft on the show. It was initially supposed to be calledConstitution, but the name was changed after Star Trek viewers started a write-in campaign urging the White House to select the name Enterprise, according to NASA.

Many scientists have said that Nimoy inspired them.Don Lincoln, a senior physicist at Fermilab, told the Associated Press that Nimoys 1970s show In Search of influenced him to get into the field.

Despite the fact he worked in fiction, anyone who can inspire that many people to look into the sky and wonder has done something really important for mankind, Lincoln told the Associated Press. The fact is that Spock was a cool geek.Scientists are not always portrayed as being very strong. Usually, theyre the guy with the tape on their glasses and their pants too high. He was clearly a person who had desirable components beyond just being smart.

Nimoy and his wife donated $1 million to theGriffith Park observatory complex. Thetheater there bears his name tohonor Leonard Nimoys expansive and inclusive approach to public astronomy and artful inspiration,a statement from theobservatory reads. Mr. Nimoy was committed to people, community, and the enlarged perspective conferred by science, the arts, and the places where they meet.
