    Google's Nexus One has dreamt of space travel for a while now, but on Monday it was finally launched into orbit aboard a CubeSat dubbed STRaND-1, which was developed by Surrey Satellite Technology and the University of Surrey's Surrey Space Centre. STRaND-1 now holds the honor of being the first PhoneSat and UK CubeSat that has made it into orbit. Alongside the HTC-made handset are an altitude and orbit control system, two propulsion setups and a Linux-based computer with a "high-speed" processor. After the Tux-friendly rig conducts a battery of tests, it'll relinquish control of much of the satellite's functions to the smartphone, which still runs Android. Not only will the mission test how commercial, off-the-shelf tech can survive in the vacuum and conduct experiments, but it'll squeeze in some fun courtesy of apps developed by winners of a competition held last year. An app called 360 will let folks back on terra firma request their own snapshots of earth taken with the phone's shooter and pin them to a map. Ridley Scott might like to say no one can hear you scream in space, but another application loaded onto the device will put that to the test by playing user-submitted shrieks and recording them with the handset's microphone as they playback. Hit the break for more details and a brief video overview of the satellite, or jab the more coverage links to partake in the app shenanigans.

    Move over, Canadarm. You may have helped the space shuttle fleet repair the Hubble Telescope and build the International Space Station, but there's another robotic tool that's the apple of the Great White North's eye. Dextre, the Canadian Space Agency's dual-armed mechanical "handyman," has successfully refueled a faux satellite from the ISS as part of NASA's and the CSA's joint Robotic Refueling Mission. Not only did the exercise demonstrate how satellites could be juiced up in space and have their lives extended, but the CSA says it's a first for the history books, to boot. Since 2011, Dextre completed a trio of tests to show how it could service satellites that weren't built for being pried opened in space. Late this week, NASA and CSA robotics controllers removed two safety caps from a washing machine-sized mock satellite, snipped two sets of retaining wires and pumped in a bit of ethanol. Sure, you could take a Frankenstein-like approach and cobble together new satellites from old ones, but Dextre's trials indicate there's promise for a proactive tactic that would keep existing hardware humming.

    DARPA made some bold promises last summer when it announced its Phoenix program to harvest dead satellites for still-valuable parts, but it didn't have much more than some concept videos to show at the time. It looks like the agency has been making some steady progress since then, though, and has today released a new video showing some of the work it's done up through November of last year. As you can see after the break, that work is all still being doing in the lab, but it covers quite a few of the components that DARPA ultimately hopes to use in space, including robotic arms and gripping mechanisms. Those tests will remain Earth-bound for the next few years, but a demonstration mission is slated for 2016 to see how the system fares on an actual satellite in orbit.

    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.

    Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Inhabitat is always interested in finding innovative uses for old technology, and this week we saw artists and designers from around the world produce new things from old, unused or outmoded gadgets. In Osaka, a local goldfish club has been transforming old phone booths into gigantic public fish tanks. In another large-scale art installation, Babis Panagiotidis used 18,000 recycled computer keys to make a life-size rocking horse. London artist Leonardo Ulian also makes beautiful, ornate mandalas from bits and pieces of old circuitry. And Benjamin Yates makes his unique coffee tables from recycled circuit boards, old VCRs and computer components.

  • MIT 'microthrusters' are the size of a penny, could reposition tiny satellites

    Bus-sized satellites require massive engines for even the slightest movements, but as far smaller structures become a possibility, a tiny driving mechanism can offer usable thrust. To serve this next-gen tech, MIT saw a need to develop "microthrusters," which are each the size of a penny and can be mounted to tiny cubed satellites. With thruster components measuring a few microns each, the magnetic levitation system is able to accommodate 500 microscopic tips that emit ion beams in a very small package, serving to push two-pound structures through space. The tiny devices have not made their way into orbit yet, but they have been tested in a vacuum chamber. Because of their size, it's possible to add several to each satellite, then enabling sophisticated movements for more precise turns. There are currently two dozen "CubeSats" in orbit, each measuring only slightly larger than a Rubik's cube, but without any thrusters to power them, positioning can't be adjusted once they're released. Because of their current location, CubeSats eventually burn up in the atmosphere, but once they're released farther from Earth, they won't be able to enter the atmosphere on their own, remaining in orbit as "space junk" even after completing their missions -- micro thrusters could also serve to move these satellites closer to the planet so they can burn up during re-entry. There's no word on when, or even if, MIT's invention will make its way to the launchpad, but you can take a closer look in the demo video after the break.

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

    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.

    It's nice to get a delivery, but what if your remote village could use the contents to finally talk to the rest of the world? That's what African communications company RascomStar-QAF is cooking up with a pilot network in the Congo's jungles. They're going in to villages throughout the African nation and installing 50 router-like femtocells -- normally used in homes for better cellphone access -- from UK vendor ip.access. Those devices will be connected through the ViaSat orbiting network to RascomStar's telecom gateway in the capital, Brazzaville. Since the femtocell setup is nearly automatic, anyone with limited technical knowledge could do it, rather than the team of engineers normally needed for more complex networks. The result would be a system which could be shipped in a box, connecting previously inaccessible areas to a telecom network -- a lot bigger deal than the WiFi veranda project we were thinking of. To see how it'll all come together, connect to the press release below for more details.

    After tacking space shuttle Discovery onto the back of a 747, the brainy gang over at NASA's READI for a new challenge -- earthquake detection. The agency's GPS-monitoring system, known as the Real-time Earthquake Analysis for Disaster Mitigation Network, is being tested with the goal of more accurately detecting the scale of quakes and, consequently, getting tsunami warnings out as soon as possible. The setup, made possible by a partnership between the Department of Defense, the National Science Foundation, and the United States Geological Survey, works by measuring ground displacement in real-time to provide a faster, more detailed assessment of imminent damage, thereby giving first responders a head start on determining aid. So the next time you look up to the night sky and wish upon a tracking star, keep in mind that sometimes privacy-skewing, positioning tech could just save your life.

  • EPFL's CleanSpace One: clearing up cosmic clutter (video)

    Where are Lone Starr and Barf when you need'em? Would that those two (fictional) interstellar handymen-for-hire were real, space agencies like Switzerland's own, could outsource the tricky and costly intergalactic housekeeping that's fast becoming a high-priority. Instead, the famously neutral country is investing 10 million Swiss francs (about $10.8 million USD) into the production of a new breed of satellites dedicated to the collection and destruction of orbital debris. The project, dubbed CleanSpace One, will tackle one of two Swiss-borne, celestial objects -- the SwissCube or Tiasat -- for its initial mission, slated for some time within the next three to five years. While our very own NASA has proposed the use of a laser to redirect these non-operational and potentially hazardous craft, the brains over at EPFL (Swiss Federal Institute for Technology) are in the process of developing a micro-electric propulsion system, in addition to a retrieval mechanism for the unit. So, what'll happen to both this outer space Rosie and her doomed cargo? Well, rather unfortunately, it's a suicide mission, as both are destined for burn-up on re-entry. Yes, it's a rather grim end to an otherwise noble voyage, but such is the price of our scientific spring cleaning.

    Start with some Arduino and Gameduino hardware, add a splash of PLAN-13 satellite tracking software from 1983, and finish with a healthy dose of libertarianism. The result? A neat little hack called Angst, designed and built by Mark VandeWettering (aka Brainwagon). It can store details of up to 750 satellites on 128KB of EEPROM memory and display their predicted orbits in all the glory of SVGA. Don't get lazy though -- the most reliable way to track those pesky snoops in the sky is still to don your anorak, step outdoors and snoop right back.

  • NASA confirms satellite hacks in Congressional advisory panel

    Acknowledging suspicions that two of NASA's earth observation satellites were hacked back in 2007 and 2008, the space agency has indeed confirmed "suspicious events" in a copy of an independent Congressional advisory panel on Chinese / US relations, obtained by Bloomberg News. NASA would not say whether the attacks were organized by the Chinese military as suspected, instead opting to assure the panel that no data was captured or manipulated and that they are working to establish an agency-wide space protection program. According to the report, hackers gained enough access to the Landsat-7 and Terra AM-1 earth mapping satellites to fully command the latter -- choosing not to act on it for unknown reasons. Probably because it'd take an actual rocket scientist in order to do so. Check out the source for more details.

    There are countless satellites, long deactivated, orbiting the Earth in what amounts to a giant cemetery in the sky. DARPA's Phoenix program sees these piles of junk not as refuse, but as a resource just waiting to be harvested. The plan is to re-engineer existing technology, like robots used in remote surgery and advanced imaging systems found in off-shore drilling platforms, for the harsh environment of space. The resulting orbiter would operate on the deceased (with the owners approval, of course), salvaging what it could and stitching them together to create new functional satellites. (Try storming those gates angry mob!) DARPA is also looking into building tiny "satlets" which could simply be clipped to the antennas of deactivated satellites, breathing new life into them and saving a significant chunk of cash. Head on after the break for a video of what the orbiting, robotic Dr. Frankenstein might look like as well as some PR.

    So we won't be zipping around with wife and kids in a flying car anytime soon, but NASA brought us ever closer to a Jetsonian future, yesterday, with the installation of its Robotic Refueling Mission (RRM) experiment. Fifteen minutes into their spacewalk, Mike Fossum and Ron Garan successfully installed the appropriate hardware on the International Space Station for pumping fuel to satellites in space. Using the Canadian-born Dextre (aka Special Purpose Dextrous Manipulator) as a gas station attendant, the RRM will eventually be used to refuel and perform minor repairs to satellites in orbit, potentially extending the time they can stay aloft. Now that that's underway, how 'bout y'all get to work on making Rosie a reality?

    Not only do American military satellites have to put up with the constant threat of ultrasonic space droppings, now they must also suffer the prying lenses of a couple of Frenchmen. Thierry Legault and Emmanuel Rietsch have spent the past two years turning consumer-grade components into a system that can keep up with the zippy and supposedly secret movements of craft like the X-37B space plane and the NROL-49 low-Earth orbit spy sat. Hit the source link and you'll see videos of the International Space Station, which they also managed to capture with steady-ish focus as it hurtled through space-time. Looks like nothing will thwart these guys, except maybe nano-satellites.

  • In lasers we trust: NASA researches 5kW galactic trash disposal system

    Space junk is a growing problem -- 200,000 pieces and counting -- and as the amount of earth's orbital debris increases, so does the chance some satellite will be involved in a cosmic collision. As this would cause much gnashing of teeth and woe for the affected terrestrial parties, some researchers from NASA's Ames Research Center have pitched the idea of moving said junk with a laser -- once again proving that everything's better with lasers. The idea is to use a 5kW ray, likely similar to the one we've got at the Starfire Optical Range, to slow our galactic garbage -- perhaps slowing it down enough to burn it up in earth's atmosphere. Current estimates say such a laser could migrate ten pieces of junk a day, which gives us the promise of a future with neat and tidy skies.

  • SSTL using Android handsets to control satellites, conquer the final frontier

    First, the Mavericks Civilian Space Foundation tested a Nexus One's ability to deal with the stress of a rocket launch. Then, Google floated seven Nexi to the edge of space to see if the phones could cope with the void. Now, Surrey Satellite Technology Limited (SSTL) is looking to launch a satellite into orbit and use a 'droid -- much smaller than the Astromech variety -- to control said satellite. SSTL, who is helping build Galileo (and is acutely aware of its cost, no doubt), views smartphones as a way to democratize access to space because they are far less expensive than purpose-built control systems. The company hasn't said which handset will be used in the satellite, but they chose Android because it allows engineers to easily modify the phone to do their bidding -- from controlling pulse plasma thrusters to handling the advanced guidance and navigation systems of the foot long satellite. Additionally, the open source OS means that they "could get people to develop apps" for the satellite. We've seen plenty of Android apps, but we're really hoping this venture is successful so we get to see apps... in space. [Thanks to everyone who sent this in]

  • New satellite receiver design teases a glorious, dish-less future

    Satellite dishes have come a long way in terms of design and size over the years, but Marcel van de Burgwal -- a grad student at the Netherlands' University of Twente -- has now invented a way to ditch the dish altogether. Channeling his inner Doc Brown, his invention revolves around an array of virtually flat antennas that receive satellite signals without the help of a concave backing. His design also conveniently eliminates the need to physically aim the receiver for reception -- much to the joy of actuaries everywhere. Instead, this task is performed by a network of small basic processors integrated into a single chip, which then bear the heavy calculation work of electronically aiming the receiver. The obvious impact of this design on consumer technology is that satellite receivers could soon make their way into all manner of handheld devices (read: smartphones). In fact, Marcel has already tested the chip's performance as a digital radio receiver for smartphones with successful results. That sounds like great news to us, but we understand if the branding folks at Dish Network are slightly less thrilled. For more details, hit the source link below.

  • College students help NASA by crashing satellite into the Arctic

    Our idea of a great evening in college was listening to some Operation Ivy and drinking a few brews before heading home to secretly pore over A Literature of Their Own. Other college kids, however, have more on their plates than that, such as those who currently work at LASP -- the Laboratory for Atmospheric and Space Physics. LASP is partially staffed by undergraduates at Colorado University, providing a low-cost alternative to more experienced labor, while giving students the kind of hands-on experience not normally available to them. One recent task, for instance, involved the crashing of ICESat, a NASA decommissioned satellite, into the Arctic. Most of it burned up in the atmosphere, while some smaller parts made their way to the Barents Sea. The mission was considered successful and, as for the students who carried it out? Well, let's just say that their nerd credentials are now rock solid.

  • Solar flares set to wreak havoc on GPS signals

    The sun's activity isn't usually a hot topic around these parts, but when it threatens to derail satellite navigation services around the world, it must surely take center stage. UK researchers have corroborated Cornell's 2006 warning that our solar system's main life-giver is about to wake up and head toward a new solar maximum -- a period of elevated surface activity and radiation. It is precisely that radiation, which can be perceived in the form of solar flares, that worries people with respect to GPS signaling, as its effects on the Earth's ionosphere are likely to cause delays in data transmission from satellites to receivers and thereby result in triangulation errors. Still, it's more likely to be "troublesome than dangerous," but inaccuracies of around 10 meters and signal blackouts that could last for hours are being forecast in the absence of any intervening steps being taken. So yes, you now have another reason not to trust your GPS too much. [Thanks, Mike]
