Video: Change of command aboard International Space Station

Flight controllers ordered two astronauts to terminate a spacewalk outside the International Space Station Friday after one of them reported a small amount of water leaking into his space helmet.

Struggling with balky electrical connectors, spacewalker Mike Hopkins managed to plug in and secure three of four thick power and data cables Saturday that are needed by a European experiment platform, leaving one cable for additional troubleshooting.

Two astronauts worked outside the International Space Station Wednesday to reposition two spare solar array ammonia coolant pump assemblies, putting a failed unit, dubbed “Leaky,” into long-term storage and attaching another, known as “Frosty,” to an appendage of the lab’s robot arm.
