Equipment water leak shortens spacewalk by 2 US astronauts

Equipment water leak shortens spacewalk by 2 US astronauts”

App users can tune in here.

A pair of NASA astronauts, Expedition 51 Commander Peggy Whitson and Flight Engineer Jack Fischer, have completed the 200th spacewalk in support of the International Space Station. Some water in Fischer's helmet delayed the spacewalk a bit, as it was supposed to begin at 6:30am EDT, but he and Whitson seem ready to head out.

For Fischer (wearing the space suit with no stripes), it will be a new experience - his first ever spacewalk.

They went straight to work removing a faulty unit that supplies electricity and data to science experiments on the outside of the space station.

Price to make minor league rehab start
Red Sox at starting pitcher David Price is scheduled to make his first minor league rehab start Sunday, according to ESPN reports. Red Sox president of baseball ops Dave Dombrowski recently remarked that Price was showing "encouraging" signs in his recovery.

As a result, NASA made a decision to trim the spacewalk down to four hours, which left time for just one task, said mission commentator Rob Navias. The fabric shield she and Fischer will be installing is a replacement for one that Whitson lost on a previous spacewalk.

Whitson and Fischer were so speedy, they were then able to tackle a few other tasks which, due to the water leak delay, NASA doubted could be done in the limited time. The adaptor will enable companies like SpaceX and Boeing to visit the station, making it an important port for the future of space exploration.

According to NASA procedures, the spacewalk can go ahead with just one functioning SCU. She holds the record for most spacewalks by a woman. For Fischer, it's his first.

The leaky hose had to be disconnected before the spacewalk could begin.

Matt Harvey rejoins Mets, apologizes for skipping game
Then they suspended him for three games without pay - costing him $84,016 - causing him to miss a start on Sunday afternoon. When asked if the text was supportive of Harvey or more challenging in tone, Collins replied, "Both".

After the first three minutes the fuel ran out and White maneuvered by twisting his body and pulling on the tether.

Above the bay of space shuttle Endeavor, NASA astronauts Jerry Ross and Jim Newman rode the big Canada arm during the STS-88 mission, attaching and outfitting the US Unity module with Russia's Zarya module, the first 2 components of the infant station.

Today, the $100 billion orbiting lab is roughly the size of a football field and a symbol of global cooperation among the 15 nations that have helped build and operate it. NASA is especially wary of leaks involving spacesuits.

"Oh my gosh, this is lovely", Fischer said as he worked 250 miles above the planet.
