Russian space debris forces space station to dodge, cancels spacewalk

NASA has called off a planned spacewalk at the last moment after a large piece of Russian space debris came dangerously close to the orbital outpost.

NASA astronauts Frank Rubio and Josh Cassada were getting ready to step out from the QUEST airlock on the International Space Station early Wednesday (Dec. 21) morning to install new solar arrays to improve the power system of the orbital outpost when their ground control team commanded them to halt the work. Instead, the space station will perform an emergency maneuver to get out of the way of a large piece of space debris that is on track to get dangerously close to the lab later today.
