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.
CubeSail parachute to drag old satellites from orbit, keep atmospheric roads clear
It's not something laypeople think about very often (space debris, for those wondering), but it's clearly on the minds of boffins at the University of Surrey. Over the years, the amount of defunct equipment hovering around beyond our view has increased significantly, with some reports suggesting that over 5,500 tonnes of exhausted kit is currently hanging around somewhere up there as a result of "abandoning spacecraft." In order to prevent the problem from growing (and to possibly reverse some of the damage), the CubeSail has been created. Put simply (or as simply as possible), this here parachute could be remotely deployed once a satellite had accomplished what it set out to do, essentially dragging it back through a fiery re-entry that it would never survive and clearing out the orbital pathway that it was using. We're told that it'll be ready for deployment in late 2011, but for now you can check out an all-too-brief demonstration vid just beyond the break.
EADS Astrium unveils European manned spaceship
It's been a great week for space geeks, what with the Phoenix Lander doing its Mars sniffing and toilet drama at the space station. Meanwhile, over in Europe, EADS Astrium Space Transportation is showing off a manned version of its Automated Transfer Vehicle (also known as the Jules Verne). This space vehicle has already been used to bring equipment to the International Space Station, but new designs reveal that Germany, France, and Italy are on board to retrofit the vehicle with seats and touch screens for humans. There's just one little problem -- the Jules Verne can't return non-humans (let alone humans) to Earth safely yet. Astrium is hoping to get the stage flying by 2013 on top of the Ariane 5 rocket in time for the end of the American Space Shuttle program in 2010, when it would replace it as the largest-payload space transport.
