Spacewalkers reconfigure station cooling system
Space station commander Scott Kelly and Kjell Lindgren carried out a busy but mostly trouble-free spacewalk Friday, routing ammonia coolant back to the prime radiator used by one of the lab’s solar arrays and bypassing a secondary radiator that was activated three years ago to help pinpoint a coolant leak.

Spacewalkers complete another round of solar array battery replacements
It took NASA more than 50 years to stage its first all-female spacewalk last October. It took three months before the second on Jan. 15 and just five days more for the third on Monday, a successful six-hour 58-minute excursion to finish installing a set of new solar array batteries aboard the International Space Station.
