DARPA SpaceView program enlists us to track space debris, save a satellite today

Space junk is an undeniable problem when there's over 500,000 dead satellites, spacecraft pieces and other human-made obstacles that could crash into active orbiting vehicles. DARPA is more than a little overwhelmed in trying to track all those hazards by itself, so it's recruiting amateur help through its new SpaceView program. The effort will buy time for non-professional astronomers on existing telescopes, or even supply hardware directly, to track the spaceborne debris without the sheer expense of growing an existing surveillance network. While that amounts to using hobbyists purely as volunteers, DARPA notes that the strategy could be a win-win for some when hardware donated for SpaceView could be used for regular astronomy in spare moments. The challenge is getting through the sign-up phase. While SpaceView is taking applications now, it's initially focusing on options for standard commercial telescopes and hand-picking those who have permanent access to hardware in the right locations -- there's no guarantee a backyard observatory will pass muster. Those who do clear the bar might sleep well knowing that satellites and rockets should be that much safer in the future.

UK engineers developing harpoon that could help space junk meet a fiery end

UK engineers developing harpoon that could help space junk meet a fiery end

Sure, we can pull space junk out of orbit with lasers or use it to cobble together new satellites, but if engineers at space firm Astrium UK have their way, space trash could be disposed of with the help of harpoons. Currently in a conceptual stage, the system is designed to shoot defunct satellites or other debris with a harpoon mounted on a "chaser satellite" and use a tethered propulsion pack to send the rubbish in an atmospheric descent where it'll burn up. Since the projectile could shoot straight through targets and result in even more garbage, it's been fashioned with a crushable portion to reduce its speed upon impact. There's no concrete word on when the outfit's solution might be put in action, but they'll present their work on Wednesday at the 63rd International Astronautical Congress in Naples (Italy, not Florida, mind you). If you can't wait to see the harpoon at work, head past the break to catch tests of an Earth-based prototype.
