  Astronauts take a spacewalk today

Two NASA astronauts are making a spacewalk outside the International Space Station (ISS) today (March 29) to follow their 6.5-hour trip online

Expedition 55 Flight Engineers Andrew Feustel and Ricky Arnold leave the station at 8:1

0 am EDT (1210 GMT) through the Airlock quest. NASA will provide live coverage at 06:30 EDT (10:30 GMT) as astronauts don their spacesuits and prepare for the day. You can watch it live here and on the Space.com home page courtesy of NASA TV.

Spacewalkers will install new handrails with built-in wireless communication equipment, replace a defective camera and remove a set of old hoses from the Space Station's cooling system, NASA officials said at a press conference on Tuesday (March 27). These age tubes seem to be responsible for an ammonia leak that NASA has been exploring for over a year, said ISS program manager Kenneth Todd during the briefing.

"We made the decision last year to isolate [the leak] on one of the radiators because we thought we might have found the potential leak scenario for the release of ammonia, and it looks A series of flex-hose pullovers that we got involved in, "Todd said. The Spacewalkers will bring the troubled hose jumpers to the station, where they will eventually be packed into a cargo ship and sent to Earth for further analysis.

Today's spacewalk comes just six days after the arrival of the astronauts on the ISS. Together with their Russian crewmate Oleg Artemyev, Feustel and Arnold left for the station on March 21, two days later docking their Soyuz MS-08 spaceship to the Poisk module.

"Do not worry that they got used to their space legs – they are both experienced space travelers and spacewalkers," said NASA spokesman Gary Jordan at the briefing.

This is Feustel's seventh spacewalk after three spacewalks during the STS-125 shuttle mission in 2009 and three for STS-134 in 2011. Arnold will tackle his third outboard deployment today after completing two at STS-119 in 2009. 19659005] Today's spacewalk also marks the 100th Spacewalk, completed by expedition crew members or longtime residents of the ISS, and 209th overall space support for space station assembly and maintenance.
