New Delhi: Two NASA astronauts Jeff Williams and Kate Rubins have begun their spacewalk outside the International Space Station (ISS).
This spacewalk is the second time for the duo in less than two weeks.
NASA TV is broadcasting the live coverage. You can also stream the spacewalk live online HERE.
During the six-and-a-half hour spacewalk, and as part of their activities, the pair will install the first of several enhanced high-definition television cameras that will monitor activities outside the station, including the comings and goings of visiting cargo and crew vehicles, says NASA.
Working on the port side of the orbiting complex’s backbone, or truss, Williams and Rubins will retract a thermal radiator that is part of the station’s cooling system.
The radiator is a backup that had been deployed previously as part of an effort to fix an ammonia coolant leak, adds NASA.
Today's spacewalk will be the fifth of Williams’ career and the second for Rubins.
As was the case for their first spacewalk together August 19, Williams will be designated as extravehicular crew member 1 (EV1), wearing a spacesuit with a red stripe, while Rubins will be EV2, wearing a suit with no stripes.
