A British test satellite has successfully used a net to capture a cubesat target, demonstrating the technology that someday could be used to clean space junk from Earth orbit.
“It worked just as we hoped it would,” said Prof Guglielmo Aglietti, director of the Surrey Space Centre. “The target was spinning like you would expect an uncooperative piece of junk to behave, but you can see clearly that the net captures it, and we’re very happy with the way the experiment went.”
If this were a real capture, the net would be tethered to the deploying satellite, which would then tug the junk out of the sky. As this was just a demonstration, the net and the box (which was actually pushed out from RemoveDebris to act as a target) will be allowed to fall to Earth on their own. Their low altitude means it should take only a couple of months before they burn up in the atmosphere.
I have embedded below the fold a video showing the net capture. It is quite spectacular. This was one of three different experiments on RemoveDebris that are testing space junk removal methods. The next is the use of a harpoon.
From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.
Unfortunately, that is exactly where that journey takes him.
The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.
He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.
