Draper Labs develops prototype Mars Hopper
The Mars rover, that self-propelled, solar powered box o' sensors 'n stuff that slowly inches along the surface (and battles the fierce environment) of the red planet may be a mainstay of space exploration, but it's certainly not the only way to get the job done. For instance, the kids at Draper Labs -- last seen in this space with their injectable nanosensor -- are in the process of developing vehicles that would (literally) leave traditional rovers in the dust. The Draper Hopper prototype is designed with a ducted fan propulsion system that uses compressed nitrogen gas to cover twenty-five miles in a few days or, at best, a few hours. By way of comparison, NASA's Spirit and Opportunity craft have covered roughly twenty miles since hitting the Martian surface in early 2004. Of course, the hoppers will have to bring fuel with them, so their lifespans will be cut drastically shorter than their wheel-based contemporaries, but we've always believed more autonomous vehicles should "live fast / die young," like Sid Vicious or James Dean. With any luck, we should see test flights by January 2011.
NASA's Athlete Mars rover does a little dance, gets down tonight (video)
Its been a few years since we last checked in on NASA's All Terrain Hex Limbed Extra Terrestrial Explorer rover -- aka, Athlete. Now a half-scale working prototype standing 15 feet tall, weighing 2.5 tons (about 2,300 kg), and capable of a 1.25 mph (2 kmph) top speed has been set loose for testing by its Jet Propulsion Laboratory creators. Its first task, set to begin next month in Arizona, will be to complete a test circuit of at least 25 miles (about 40 km) in two weeks under its own power. Failing that, we hear Woz is looking for a dance partner. See what we mean in the video of Athlete demonstrating a flare for cargo transport after the break.
Spirit Rover may not live through bitter Martian winter
NASA's Opportunity and Spirit rovers touched down on Mars in 2004 for a planned 90-day tour; six years and a few serious snags later, the latter of the two is facing its death of cold. Since March 22, 2010, Spirit's been slumbering on the surface -- stuck and unable to generate enough power to communicate -- and while internal heaters and a favorable position on a sun-facing slope allowed the rover to survive previous Martian winters, this time the chances aren't so good. "The rover is experiencing the coldest temperatures it's ever been in – equivalent to about minus 55 degrees Celsius," NASA told Space.com. Should Spirit wake up next year, it will resume a stationary mission to help scientists determine whether Mars has a liquid core, but if not there's always the chance it might spontaneously regain power still find utility in another decade or four. Still not on the docket: ever returning home.
James Cameron convinces NASA to use 3D camera on next Mars mission
What do you do once you've broken your own record for the world's highest-grossing picture film? Well, you go offworld, of course. James Cameron, in his infinite benevolence and multidimensional wisdom, has convinced NASA bigwigs not to forgo the inclusion of a high-res 3D camera on the Curiosity (aka Mars Science Laboratory) rover, which is set to depart for the red planet in 2011. Budget overruns had led to the scrapping of the autostereoscopic idea, but the director-man -- who has been involved with this project for a good few years now -- felt the results of the mission would be far more engaging if people could see them in 3D. Hey, if he can make us watch the Blue Man Group reenactment of Fern Gully, don't bet on Cameron failing to make extraterrestrial rubble interesting with his 3D voodoo.
Robot Hall of Fame expands to include Da Vinci, Terminator, Roomba
Forget those "sporting" Halls of Fame -- the real HOF is right here. Since 2003, the Robot Hall of Fame has been honoring robots and creators at an exhibit in Pittsburgh, Pennsylvania, and now we're seeing the latest handful of noteworthy creatures take their rightful place in history. For those unaware, the Robot HOF is maintained by Carnegie Mellon University and the Carnegie Science Center, and an international jury of researchers, writers, and designers has just selected five new bots to join the cast: Mars rovers Spirit and Opportunity, the T-800 Terminator (yes, that Terminator), the Da Vinci surgical system, iRobot's Roomba and 'Huey, Dewey, and Louie' from the 1972 sci-fi flick Silent Running. Could you have imagined a more fitting five? If so, sound off below!
NASA investigates problems with Mars Spirit rover
They've manged to make it to the five-year mark despite a few considerable bumps in the road, but it looks like one of the Mars rovers has once again hit a snag, and NASA is now furiously trying to sort out the problem. Apparently, the issue first arose earlier this week when Spirit reported that it had received its driving commands but didn't move. Things were then further complicated later in the day when Spirit failed to record its daily activities, and it seems to have been all downhill since, with the rover unable to even locate the sun in order to reorient itself. What's more, while they're still trying to run some diagnostics to pinpoint the problem, NASA engineers say that the troubles could possibly be caused by cosmic rays hitting the rover, which we all know can only lead to one thing.... zombie rovers.
Mars rovers mark off five years of tireless servitude to humanity, boredom
NASA's Spirit rover landed on Mars on January 3rd, 2004, with Opportunity joining up 21 days later, and both are going strong five years later. Still no sign of Don Cheadle.
NASA won't dampen exploratory spirit of Mars rovers
Back in November, we knew things weren't looking up for the twin Mars rovers, but it seems that both Spirit and Opportunity will still be doing their respective thangs after a letter foreshadowing their doom was rescinded. Reportedly, the entity was tasked to slash $4 million from the project's budget just yesterday, which would have forced Spirit into hibernation and limited Opportunity's opportunities by mandating that commands be sent up every other day (versus everyday now). As it stands, NASA has issued a confirmation that neither creature will be affected, but given the apparent belt-tightening, we're curious as to whether Scarecrow will still see liftoff next year.[Via Physorg]
NASA's Mars Opportunity rover falls on hard times
NASA's Mars Opportunity rover has already long outlasted its original 90 day mission, but it looks like the go-getter bot is now really starting to show its age, as NewScientist reports that problems with two key instruments have left the rover "crippled and blinded." As NewScientist points out, however, these latest issues are far from the first to plague Opportunity (and its counterpart, Spirit), and it's still suffering from a malfunctioning wheel and an "arthritic" robotic arm, both problems of which first cropped up in 2005. While NASA has currently suspended all work involving the rover's rock grinding tool and its infrared spectrometer, it's apparently hoping to get the spectrometer back up and running by shaking off some of the dust causing the problems, and at least one NASA official expects both rovers to keep "going for years more."
Britain's "Bridget" rover hopes to explore Mars
Even though we were pretty sure that the whole "life on Mars" issue had already been settled, scientists are still hell-bent on sending robots to scope out the Red Planet to look for tiny Martians, with the British unveiling a new rover today that promises to school hometown favorites Spirit and Opportunity at that very task. "Bridget," as the six-wheeled bot is known, can supposedly cover in just six months the same 6.2-mile stretch that's taken the American rovers over two years, thanks to a guidance system that allows for greater autonomy and requires less terrestrial control. Designed to compete for a spot on the European Space Agency's planned 2011 ExoMars mission, Bridget sports a two-meter drill, a so-called "life marker chip," and a micro seismometer, among other toots, to help enable the Agency's long-term goal of safely sending humans to our neighbor planet. And because half the battle is just getting there, engineers equipped the new bot with sensors that will let on-board airbags and parachutes guide it to a safer, more controlled landing -- ensuring that Bridget doesn't go MIA like the Beagle 2 rover in 2003, .
$125,000 record player runs on Mars Rover motor
Behold the Clearaudio Statement. If you listen carefully you can hear the sighs of a thousand audiophiles at the sight of this incredibly excessive record player. The $125,000, 770-pound unit -- based around the same motor that they used in the Mars Rover -- turns a platter to such exacting specifications that, well, we're not really sure why it needs to do that. But suffice it to say that there isn't a lot of vibration or unevenness up in here. Neither does common sense reign. Be sure to follow the link for more audiophile porn.[Via Music Thing]
