Astronauts finish repairs to space station cosmic ray detector
During a fourth spacewalk Saturday to wrap up repairs of the coolant system in a $2 billion cosmic ray detector, Italian astronaut Luca Parmitano and Drew Morgan discovered a leak in one of eight coolant lines that were spliced into a new pump module during three earlier excursions. But Parmitano was able to tighten a fitting on the line and the astronauts were able to complete the repair work, setting the stage for the instrument to resume science operations.

Successful spacewalk ends with water leak
Astronauts Barry “Butch” Wilmore and Terry Virts floated outside the International Space Station Wednesday for the second of three spacewalks to help ready the complex for dockings by commercial crew capsules. Back inside the station’s airlock, Virts reported a small amount of water in his space helmet, but officials said he was not in any danger.
