Gotcha! Tossed net captures space junk in orbit-cleanup experiment

Cape Canaveral: A tossed net has managed to capture space junk in a demonstration of ways to clean up debris in orbit.

In the British-led experiment, a big net was cast from a mini satellite on Sunday. The net successfully wrapped around its target, an inflated structure that had just been deployed as part of the test. The distance covered nearly 6 metres.

"This is not sci-fi. We repeat, not sci-fi," tweeted the Texas-based company NanoRacks, which developed the space station's microsatellite deployer.

The University of Surrey's Guglielmo Aglietti said on Thursday the target was spinning faster than expected, but that made the test even more realistic. The objective is to show ways of removing debris from orbit, which is cluttered with old rocket and spacecraft parts. This debris poses a hazard not only to the International Space Station and its crew, but to the Hubble Space Telescope and other satellites.

The net – about 5 metres across – and its target will eventually fall out of orbit together and burn up.

A harpoon, meanwhile, will be tested in a similar manner in February, according to Aglietti.

The experiment was deployed into orbit from the space station in June, two months after it arrived.
