CAPE CANAVERAL, Florida - Two Russian cosmonauts are spacewalking again for the second time in under a week.
Fyodor Yurchikhin and Aleksandr Misurkin ventured out of the International Space Station on Thursday morning. They stepped out last Friday as well.
This time, the cosmonauts will replace a laser experiment on the Russian side of the orbiting outpost. They also will check six antennas attached to Russia's main compartment. On Monday, an antenna cover came off and floated away. Russian space officials want to know which antenna it came from. The spacewalkers will also double-check the remaining covers to make sure they're secure.
NASA, meanwhile, has suspended all U.S. spacewalks while the investigation into last month's near-drowning continues. An Italian astronaut's helmet filled with water during a spacewalk. He barely made it back inside.
