Two US astronauts overcame an early equipment glitch to complete an abbreviated spacewalk outside the International Space Station on Friday, accomplishing all the major tasks initially planned for a longer excursion in four hours, NASA said.
NASA astronaut Peggy Whitson is seen during a spacewalk during Expedition 50 aboard the International Space Station. There was a leakage of water at the connection point of the device and the spacesuit of astronaut Jack Fischer. The hose is one of two that provide water, oxygen, power, cooling and communications for astronauts before they float outside.
The leaky hose had to be disconnected before the spacewalk could begin.
"This was not a leak in Fischer's suit", NASA said, adding "The sharing of the SCU resulted in additional draw in battery power from the suits during preparations while in the Equipment Lock, reducing the battery power available for use during the spacewalk".
Fischer, who is wearing a suit with no stripes, is undertaking his first ever spacewalk. Fischer agreed, saying he was humbled to follow in the legacy. It will be replaced with a unit delivered to the station last month aboard the Orbital ATK Cygnus cargo spacecraft.
Fischer's enthusiasm for the beauty of the Earth beneath him was apparent throughout the spacewalk. Whitson, on the other hand, has performed more spacewalks than any other woman. Fischer, extravehicular crew member 2, will wear the suit with no stripes on his first-ever spacewalk. This was her ninth. NASA is especially wary of leaks involving spacesuits.
The small leak of water led to the brief delay in the start of spacewalk.
The two astronauts also replaced a faulty electronics box that routes commands and data to experiments which weighed about 90 kg and installed a cable that is used to troubleshoot a cooling system problem with the dark matter detector of the International Space Station.
