WASHINGTON (May 10, 2013)--Two astronauts aboard the International Space Station will take an impromptu spacewalk Saturday to work on a leaking coolant line.
The leak forced the shutdown of one of eight solar panels, but NASA said the space station can operate fine with only seven panels providing power.
The line chills power systems, but power was rerouted and is operating normally.
The six-member crew is not in danger, NASA said.
The leak is in one of the radiator lines that cool the power systems, and there has been a leak before in the same area.
The astronauts have trained for this type of repair.
