NASA astronauts replace blurry camera on robot arm

Astronauts went spacewalking Friday to provide some necessary focus to the International Space Station's robot arm. The main job for commander Randy Bresnik and teacher-turned-astronaut Joe Acaba was to replace a blurry camera on the new robotic hand that was installed during a spacewalk two weeks ago. The two men were supposed to go spacewalking earlier this week, but NASA needed extra time to rustle up the repair plan.

The Deep Space Gateway will orbit Earth and the moon and will open up opportunities for future exploration of deep space, as well as a return to the moon and missions to Mars.
