Space Junk Near-Miss Sends Astronauts Scrambling Into Escape Pod

Soyuz and ISSThe International Space Station had a close shave this afternoon when a diminutive piece of space debris whizzed past the station at dangerously close range, forcing the first ever evacuation of the station. The three crew members took shelter in the attached Russian spacecraft that serves as an emergency lifeboat. The debris missed, and the astronauts quickly returned to the station after just 11 minutes aboard the Soyuz spacecraft. But the unusual event offered a reminder that astronauts and spacecraft are increasingly playing a deadly game of space-debris dodge ball in orbit [Washington Post].

The object that prompted the evacuation was a fragment of a motor used to launch a satellite. Although the piece of debris was only about one-third of an inch long, experts say that even tiny pieces of space junk can cause great damage, as objects in orbit travel at great speeds. Mission controllers detected the orbiting debris Wednesday night, too late for the crew to take evasive action, Humphries said. In previous instances, controllers have been able to maneuver the station out of the way of a threatening piece of space junk, “but because of the late notice, we didn’t have time to coordinate that,” he said [CNN].

NASA officials say the evacuation was a precaution triggered by realization that the piece of debris was going to pass within 2.8 miles of the station. If the debris had struck the station and caused serious damage, the crew might have had to fly the Soyuz back down to Earth and leave the multibillion-dollar orbiting outpost under remote control [MSNBC].

Space agencies say that space debris is a growing problem as old satellites and discarded rocket boosters are piling up in orbit. Last month two satellites collided in orbit for the first time, providing a vivid demonstration of what can go wrong when two objects traveling at about 17,500 miles per hour ram into each other. And that incident only made matters worse: NASA officials say that at least 600 pieces of debris spun off from the collision. U.S. Strategic Command routinely tracks over 18,000 pieces of debris as they hurtle through space.

    This is probably the first time I’ve read about a space escape pod, and it wasn’t sci-fi.

    Net guns! Shoot net guns at the debri to capture it and then de-orbit it with a toss from the robot arm or something. Capture the debris and then use a railgun type device to de-orbit at high velocities. This will have a double function of being able to add velocity to the space station itself, even in miniscule amounts. It will be one way to turn the energy of the solar panels into motive power for the space station.

    Net guns sound neat! So does this proposal for water cannons that would blast debris down towards the atmosphere, where it would burn up.

    wow, Why not, lets play kids…………the window is disappearing.Dig in and learn.Fight. Good luck my friends, Jason Thomas Shields 46303 IN. Ill keep the light on as long as I can………..
