NEW YORK, October 15. /TASS/. Two NASA astronauts have started a planned spacewalk to replace a failed power regulator outside the International Space Station, the National Aeronautics and Space Administration said on Wednesday.
Flight Engineers Reid Wiseman and Barry Wilmore of Expedition 41 "will replace a failed power regulator known as a sequential shunt unit, which failed in May. The unit regulates power from the 3A solar array," NASA said in a statement.
The spacewalkers "also will relocate equipment on the station’s exterior to begin setting the stage for a reconfiguration of the orbiting complex to accommodate future commercial crew vehicles," NASA said.
The spacewalk is scheduled to last for about seven hours.
The first Russian spacewalk of Expedition 41 will take place on October 22, NASA said.
