On their thirty second day in area, NASA astronaut Tim Kopra and Tim Peake of the European Area Company started their Additional-Vehicular Exercise(EVA) from the U.S. Quest airlock at 12:48 p.m. GMT. whereas the ISS was flying 250 miles over the Southern Indian Ocean.

They rapidly translated some 200 toes to the S6 truss on the starboard fringe of the area station to take away a defective energy regulator referred to as a Sequential Shunt Unit(SSU) that failed on November 13 2015.
Working in tandem, the pair eliminated the previous Sequential Shunt Unit whereas the station was in orbital night time time. This eliminated the opportunity of sparking as no energy was being generated by the station’s photo voltaic arrays presently. Kopra and Peake put in a brand new SSU a short time later. The brand new unit is nicknamed “Dusty” because it has been aboard the complicated since 1999.
Aboard the Worldwide Area Station are eight energy channels alongside which solar energy generated by the station’s eight photo voltaic arrays flows to function on board methods. The aim of the SSU is to manage energy output of the photo voltaic arrays to 160 volts. The ISS can function with solely seven channels in operation, but when one other had been to fail some on board methods would have to be shut down.
With the first activity of the Additional-Vehicular Exercise(EVA) full, the spacewalking duo targeted their consideration on routing a sequence of cables that shall be used to arrange the orbiting laboratory for the upcoming set up of Worldwide Docking Adapters on Pressurised Mating Adapters that may function docking ports for future business crew and resupply automobiles visiting the Worldwide Area Station.
Nonetheless shortly after 4 p.m. lead spacewalker Kopra quickly seen {that a} quantity of chilly water had discovered its approach into his helmet. He additionally famous that his shoulders and wrists had been additionally moist because of the leak.
Renfrew later spoke to NASA Public Affairs Officer Rob Navias on his resolution which you’ll be able to watch right here.
“We’re in a terminate case,” radioed NASA astronaut Reid Wiseman in Mission Management, relaying Renfrew’s resolution. “We wish you to start out heading again to the airlock.”
This follows the same incident in July 2013 wherein ESA astronaut Luca Parmitano’s helmet full of a big quantity of water, resulting in the instant abort of that exact spacewalk.
This was the 192nd spacewalk in assist of area station meeting and upkeep. As we speak additionally marks the primary time a British citizen has performed an EVA with Tim Peake making the primary spacewalk of his profession. As we speak’s tour marks the third spacewalk for Tim Kopra.
