Astronauts aboard the International Space Station took refuge inside their Russian-built Soyuz lifeboat Thursday when a potentially life-threatening piece of space debris zipped too close to their orbiting laboratory.
The three astronauts, two Americans and one Russian, moved into the station's attached Soyuz TMA-13 spacecraft at 12:35 p.m. EDT (1635 GMT) as a safety precaution in case the debris - a small piece of a spent satellite motor - slammed into the orbiting lab and ripped a hole in its outer hull. The astronauts were ready to evacuate the space station if the debris hit the station and depressurized its living space.
Notice of the incoming debris came overnight, too late for flight controllers to plan a maneuver to fire the station's thrusters and put more space between it and the space trash, NASA officials said. But the debris apparently did not impact the $100 billion orbiting lab as it flew 220 miles (354 km) above Earth.
"We're all happy the [debris] passed with no impact," NASA's Mission Control radioed up to the crew from the Johnson Space Center (JSC) in Houston. "That's great news."
NASA spokesperson Brandi Dean at JSC told SPACE.com that the astronauts did not fully close the hatches between the Soyuz and the rest of the space station during the precaution, but they were prepared to do so if required. The satellite motor remnant was expected to zoom past the station at a distance of about 2.4 miles (4 km), Dean said.
