VIDEO: Space Station repairs under way

Astronauts at the International Space Station have completed the first of a series of spacewalks to carry out urgent repairs.

Two Americans astronauts conducted the first of three possible spacewalks needed to mend the station’s critical cooling system – half of which automatically shut down last week after detecting abnormal temperatures.

Nasa said the situation was potentially serious but not life-threatening.
