ICYMI: Orbital space junk is putting us in jeopardy

Today on In Case You Missed It: The US Air Force is moving its Space Surveillance Telescope to Australia to track space junk littering geosynchronous orbit. That's the orbit 22,000 miles away from our planet where satellites mirror the Earth's ro...

ICYMI: A space-based full service stop, bat drone and more

Today on In Case You Missed It: DARPA's own AAA satellite service to service satellites orbiting Earth could launch in about five years, if all the testing goes as planned. A new drone is based on the form of a bat and the resemblance is uncanny. A...

Air Force might shutter satellite- and space junk-tracking Space Fence soon

DNP RIP Space fence

We imagine the Air Force is none too pleased that Space Fence might shutter as soon as September 1st due to budget constraints, according to leaked memos obtained by Space News. Space Fence, a powerful system of radars that track satellites and space junk orbiting the Earth, performs 40 percent of the Air Force Space Surveillance Network's observations. It can detect objects as small as a basketball up to 24,000 kilometers away and can constantly beam info back to the planet with no human input. It's no surprise then that the airmen called it a "critical defense system" when they tried to save the project in July -- an endeavor they failed if this info turns out to be true. Before anyone worries about unmonitored celestial debris hurtling toward Earth, know that a plan to build a more advanced Space Fence replacement exists. The only reason why it's not in the works is because it has yet to secure funding, leading this editor to think that someone really needs to get started engineering a money tree.

Murchison Widefield Array goes live, will study the sun, space junk, the early universe and more

Murchison Widefield Array goes live, will study the sun, space junk, the early universe and more

We hope IBM's hardware is ready to chew through the feast of data it's going to receive, as the Murchison Widefield Array (MWA) radio telescope is officially open for business science. Located in the outback on the same site as the Australia SKA Pathfinder, it's one of three "precursor" programs that'll help steer future development of the extra powerful Square Kilometer Array. The MWA low-frequency telescope has plenty of work to be getting on with, and some of its first tasks include gazing into the sun to observe solar flares, storms and other activity, as well as scanning the Milky Way for the likes of "black holes and exploding stars." It'll also look into the tracking of hazardous space garbage using FM radio waves that are lost to the void, and explore the early life of the universe as far back as 13 billion years. According to Curtin University's Professor Tingay, the MWA's commendable work ethic (read: data quality) means we could see initial results from some of these projects "in as little as three months' time."

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.

Pentagon starts Phoenix trial to harvest defunct satellites, MacGyver new ones from orbit

pentagon-starts-phoenix-dead-satellite-trial

The Phoenix Frankenprogram to harvest the corpses of expired satellites and cobble together new ones seemed like one of DARPA's more daft ideas, but this one has actually kicked off its first phase of development. The plan is to first launch a service craft -- replete with robotic arms and enough processing horsepower to work independently if needed -- followed by the tiny base-unit skeleton satlets. The service mothership would dip into an orbital area called the "graveyard", grabbing pre-chosen cadavers and picking off usable parts, especially valuable antenna arrays, with its robo-limbs. Those parts would be jury-rigged to the bare-bones units, creating usable Pentagon satellites and saving the $10,000 per pound launch cost. So far, a $2.5 million contract to develop the needed technology has been put in place, and bids for the no-frills satlets went out last week. Plenty of dirty work is still needed, so check the video after the break to see if the overly-elaborate plan can un-moot $300 billion of orbiting cold metal.
