UK engineers are developing a system to harpoon rogue or redundant satellites and pull them out of the sky.
It is a response to the ever growing problem of orbital junk - old pieces of hardware that continue to circle the Earth and which now pose a collision threat to operational spacecraft.
The harpoon would be fired at the hapless satellite from close range.
A propulsion pack tethered to the projectile would then pull the junk downwards, to burn up in the atmosphere.
"Space has become a critical part of our infrastructure - from weather forecasting and Earth observation, to GPS and telecommunications," said the harpoon’s designer, Dr Jaime Reed, from Astrium UK.
"Space junk poses a real threat to these vital services if we do nothing about it, and so it’s very important we develop capture technologies to remove some of this material. Studies have shown that taking out just a few large items each year can help us get on top of the problem."
Dr Reed’s proposal is for a barbed spear about 30cm in length. It would be mounted on a "chaser satellite" that would edge to within 100m of a junk object.
Pictures sent to the ground would then be used to assess the target, before the chaser was moved to within perhaps 20m to take a shot.
Once the harpoon is hooked through the skin of the rogue satellite or rocket stage, the chaser could either pull on a trailing polymer cord itself or deploy a separate thruster unit to do the job of dragging the aimless drifter towards Earth.
This is research in its very early stages. The BBC has filmed firing tests of a prototype harpoon at Astrium UK’s Stevenage base.

Meet AISight – The Artificial Intelligence Software Being Installed on CCTV Networks Globally 2014 04 24 If you thought that CCTV cameras tracking your every move in public was bad enough, you’re going to just love AISight (pronounced “eyesight” of course). The invention of a Houston, Texas based company called BRS Labs (which stands for Behavioral Recognition Systems) is headed by former secret service special agent John Frazzini, and this Orwellian surveillance platform brings artificial intelligence ...
Biofuel Made From Corn Waste Less ‘Green’ Than Gasoline 2014 04 24 Biofuel created from corn waste may not be the clean, eco-friendly oil alternative the United States government is hoping for. A new study has found that fuel generated from harvested corn leftovers creates more greenhouse gases than conventional gasoline — at least in the short term.
The fuel under study, called cellulosic ethanol, has been touted in recent years as a ...

John Kerry and the Pope set to face off with Jewish Knight Templars on the Temple Mount 2014 04 24
This is the week that supposedly spells the end of the peace process or its end. My money is on a continuation that has no real substance or direction.
What’s the alternative?
With Passover and Easter over, Secretary Kerry can return to the Middle East crisis. This, after dealing so successfully with crisis in the Ukraine. [Is the author joking? - RIC]
