WASHINGTON: Astronauts are making their third and final spacewalk of the current shuttle mission to the International Space Station (ISS).
American Robert Behnken and UK-born Nicholas Patrick are on a 6.5-hour outing to put the finishing touches on the recently-fitted Tranquility Node.
Among other tasks, they will prepare the module's new observation deck, or "cupola", for its first opening. Tranquility represents the last major component in the building of the ISS.
Besides a good deal more space, Tranquility will provide ISS astronauts with an unprecedented view of the Earth and of approaching vehicles that the station has lacked until now.
