NASA JPL controls rover with Leap Motion, shows faith in consumer hardware (video)
If you think using the Leap Motion controller for playing air guitar and typing without a keyboard was cool, try using it to control a NASA rover. Victor Luo and Jeff Norris from NASA's Jet Propulsion Lab got on stage at the Game Developers Conference here in San Francisco to do just that with the ATHLETE (All-Terrain Hex-Limbed Extra-Terrestrial Explorer), which was located 383 miles away in Pasadena. As Luo waved his hand over the sensor, the robot moved in kind, reacting to the subtle movements of his fingers and wrists, wowing the crowd that watched it over a projected Google+ Hangout. We spoke with Luo and Norris after the panel to gain further insight into the project. As Luo explains, one of JPL's main goals is to build tools to control robots needed for space exploration. Seeing as the gaming industry is already rife with user-friendly controllers ripe for the plucking, it made sense to harness them for the job. "We're very used to the bleeding edge," he said. "From the Kinect to the PlayStation Move, they represent major investments into usability." Hit the jump for our impressions of the simulation software, a look at JPL's grander goal and for video clips of the demo and panel itself.
NASA Jet Propulsion Laboratory's Tom Rivellini backstage at Expand (video)
If you truly were terrified during the Seven Minutes of Terror that saw the Curiosity Rover successfully land on Mars, you can blame NASA Jet Propulsion Laboratory's Tom Rivellini. As JPL's Principal Engineer for Entry Descent and Landing Systems, Rivellini co-invented the sky crane landing system that helped the rover plant its wheels on the red planet. He met with us backstage to discuss the challenges that have been encountered with these feats of engineering, and what he's currently working on: a new parachute and heat shield system for landing spacecraft carrying humans or larger rovers on Mars.

Curiosity rover finds conditions on Mars that could have supported living microbes
"A fundamental question for this mission is whether Mars could have supported a habitable environment," says lead Mars Exploration Program scientist Michael Meyer, quoted in a NASA press release today. "From what we know now, the answer is yes." He's referring to the latest Curiosity findings announced at a press conference today, which NASA says "shows ancient Mars could have supported living microbes." That evidence specifically comes from powder the Curiosity rover drilled out of a rock near an ancient stream bed in Mars' Gale Crater, which contained sulfur, nitrogen, hydrogen, oxygen, phosphorus and carbon -- "some of the key chemical ingredients for life," as NASA puts it. Mars Science Laboratory scientist John Grotzinger further explains that "we have characterized a very ancient, but strangely new 'gray Mars' where conditions once were favorable for life," adding, "Curiosity is on a mission of discovery and exploration, and as a team we feel there are many more exciting discoveries ahead of us in the months and years to come." You can find the full announcement after the break.
Curiosity rover leaves safe mode, remains in Martian limbo
The Curiosity rover has been in an especially precarious position since late last week, when a memory glitch forced it into a safe mode while NASA prepared a backup and diagnosed the trouble. We're glad to report that the worst is over. Scientists have confirmed that the rover left safe mode later on Saturday and started using its high-gain antenna for communication a day later. However, it's not quite out of the woods yet -- if Mars had woods, that is. The backup is still taking on the information it needs to assume full responsibility, and NASA wants to evaluate the suitability of the one-time primary computer as the new backup. Nonetheless, all the early indicators point to Martian exploration going back on track within days.
Curiosity rover to stay in 'safe mode' for days while NASA tackles glitches
NASA's Curiosity rover has mostly had smooth sailing since it touched down on Mars last year. Unfortunately, it's in a more precarious position as of this past Thursday. After noticing corrupted memory files on the robot's primary computer, overseers have kicked Curiosity into a "safe mode" with a backup computer while they determine what's wrong and deliver any viable fixes. Don't think of this like you would the Safe Mode on a Windows PC, though. While the backup can serve as a replacement for the main computer, project manager Richard Cook warns Space.com that it will likely take "several days" to supply enough information that the failsafe can take over. NASA will switch back to the main computer if and when it's ready; if it is, the agency hopes to harden the code against future flaws. Curiosity will effectively stay on ice in the meantime... and not the variety it might want to find.
Curiosity spends holidays in Yellowknife Bay, immortalized on special Foursquare badge
While many of us were opening presents and having our fill of mulled cider, NASA's trusty Curiosity rover was busy at work capturing panoramic views of Yellowknife Bay, a shallow area of unusual terrain on the Red planet. Jokingly dubbed "Grandma's house" by the crew, the rover spent over 11 Martian days there so that handlers could take some time off for the holidays. When they get back, the space vehicle will hopefully have provided enough data to pinpoint a potential drilling area so it can drill, collect and analyze rock samples using onboard tools -- a feat never-before attempted on Mars. The Curiosity rover has, however, checked in on Foursquare on Mars, which is a feat no one else is likely to attempt. In continued collaboration with the social media platform, NASA is now providing a Curiosity Explorer badge to anyone who checks in to a NASA visitor center or a venue categorized as a science museum or planetarium. Badge recipients will get this message: "Get out your rock-vaporizing laser! You've explored your scientific curiosities just like NASA's Curiosity rover on Mars. Stay curious and keep exploring. You never know what you'll find." No idea if you'll get a free "scoop" of space ice cream or a hand in the next Mars mission along with it, but we're behind anything that boosts the public's interest in space.
NASA plans to put another Curiosity-like rover on Mars in 2020
Who says NASA doesn't have big plans for the next decade? Following the universally extolled launch of Curiosity onto Mars' surface earlier this year, the American space entity is reportedly looking to launch another in 2020. The news was dealt at the American Geophysical Union conference in San Francisco today, and while details are thin at the moment, we're hearing that the next-generation 'bot will be "based on Curiosity." John Mace Grunsfeld, a NASA Management Astronaut and the Associate Administrator of the Science Mission Directorate at NASA headquarters, was cited as the man responsible for divulging the news. All told, the budget for the so-called "Science Rover" will be around $1.5 billion, with none of that funding to be raked in from other departments. The launch is part of a multi-year Mars program, which NASA says "affirms the agency's commitment to a bold exploration program that meets our nation's scientific and human exploration objectives." The planned portfolio includes the Curiosity and Opportunity rovers; two NASA spacecraft and contributions to one European spacecraft currently orbiting Mars; the 2013 launch of the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter to study the Martian upper atmosphere; the Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) mission, which will take the first look into the deep interior of Mars; and participation in ESA's 2016 and 2018 ExoMars missions, including providing "Electra" telecommunication radios to ESA's 2016 mission and a critical element of the premier astrobiology instrument on the 2018 ExoMars rover. More details can be found in the full release embedded after the break.
NASA Curiosity rover digs Mars, finds sulfur, chlorine and organic traces of unknown origin
Since NASA's Curiosity rover made its way to Mars, it's been sending back a wealth of data from our rust-colored planetary neighbor: landscape photos, radiation readings and even evidence of liquid water. We can now add soil composition to the list, as Curiosity became Earth's first visitor to the Red Planet to both gather and analyze Martian soil on its own. What's Mars made of? Well, after scooping up some loose sand, Curiosity's Sample Analysis at Mars (SAM) suite and the Chemistry and Mineralogy (CheMin) instruments found a menagerie of chemicals, including sulfur, chlorine, and traces of carbon-based materials. Don't get carried away thinking there's life on Mars just yet, however, because NASA's boffins aren't sure the organic molecules are native -- they may have come from Earth on this, or a previous mission. Still, the analysis is a significant step in unlocking Mars' secrets, and the high quality data resulting from it will keep NASA's best and brightest busy as Curiosity continues sampling Martian dirt in the coming months. Those interested in learning more can check out the source below or tune into the press conference after the break.
Curiosity rover finds radiation levels on Mars are safe for humans
It's been three months since NASA's Curiosity rover set foot wheels down on Martian terrain, and now the space agency has divulged what it's learned about radiation on Mars. Marking the first time radiation has been measured from the surface of another planet, preliminary data collected using the rover's Radiation Assessment Detector (or RAD for short) revealed that levels on the ground are similar to what astronauts encounter on the International Space Station. What's that mean for space travel? "The astronauts can live in this environment," Don Hassler, principal investigator on Curiosity's RAD hardware, said in a press conference. However, humans would still experience higher levels of radiation on the way to and from the red planet than on its surface. The results are encouraging, but they're just one of many developments left before Homo sapiens set foot on Mars. For more details on the RAD's findings, look below for the press release.
A Tour of Astrobotic Technology's lunar rover lab at Carnegie Mellon (video)
Things are buzzing late Monday afternoon at Carnegie Mellon's Planetary Robotics Lab Highbay. Outside, in front of the garage door-like entrance, a trio of men fills up a kiddie pool with a garden hose. Just to their left, an Enterprise rent-a-truck backs up and a handful of students raise two metal ramps up to its rear in order to drive a flashy rover up inside. I ask our guide, Jason Calaiaro, what the vehicle's final destination is. "NASA," he answers, simply. "We have a great relationship with NASA, and they help us test things." Calaiaro is the CIO of Astrobotic Technology, an offshoot of the school that was founded a few years back, thanks to Google's Lunar X Prize announcement. And while none of the handful of vehicles the former student showcases were made specifically with the government space agency in mind, given the company's history of contractual work, we could well see them receive the NASA stamp of approval in the future. Asked to take us through the project, Calaiaro tells us, quite confidently, that the trio of vehicles behind us are set to "land on the moon in 2015," an ambitious goal set to occur exactly three weeks from last Friday.%Gallery-168976%
NASA's Curiosity rover checks in on Foursquare, gives Mars its first mayor
Yes, seriously. NASA announced on Wednesday that its Curiosity rover had "checked in" on Mars via Foursquare. Marking the first check in from another world, the robotic rover will utilize the location-minded social network to share updates and pictures while visiting the Red Planet. While Curiosity will continue to explore the possibilities of Mars being able to sustain life, it would appear that the fourth planet from the sun just got a brand new mayor. Something tells us the universe's rarest badge is about to be bestowed.
NASA's Curiosity rover finds ancient streambed on Mars, evidence of 'vigorous' water flow
Curiosity may have spent a while limbering up for the mission ahead, but now it's found evidence of an ancient streambed on Mars that once had "vigorous" water flow. Photos of two rock outcroppings taken by the rover's mast camera between the north rim of Gale Crater and the foot of Mount Sharp reveal gravel embedded into a layer of conglomerate rock. The shape of the small stones indicate to NASA JPL scientists that they were previously moved, and their size (think from grains of sand to golf balls) are a telltale sign that water did the work instead of wind. Evidence of H2O on Mars has been spotted before, but this is the first direct look at the composition of riverbeds NASA has observed from above. According to Curiosity science co-investigator William Dietrich, it's estimated that water flowed at the site anywhere from thousands to millions of years ago, moved at a clip of roughly 3 feet per second and was somewhere between ankle and hip deep. "A long-flowing stream can be a habitable environment," Mars Science Laboratory Project Scientist John Grotzinger said. "It is not our top choice as an environment for preservation of organics, though. We're still going to Mount Sharp, but this is insurance that we have already found our first potentially habitable environment."
Rovio takes Angry Birds Space for a spin with NASA's Curiosity Mars Rover, teases Red Planet for fall (video)
It was almost as inevitable as gravity, really. Rovio has teamed up with NASA to offer a special, Curiosity-themed episode inside Angry Birds Space. The trek has the avians scouring 20 levels of the Martian landscape with a few bonuses thrown in for good measure. Just like your favorite childhood breakfast cereal, there's even a token healthy ingredient -- in this case, a chance for gamers to learn about Curiosity's exploration whenever they're not busy smashing pigs. Android and iOS users can dip into the new chapter right after they update, but that's not even the full extent of Rovio's plans. If the environs of Gale Crater are too limiting, you'll be glad to hear that the game developer is teasing a full-scale Red Planet variant for the fall.
Curiosity rover flaunts its battle scar, wind sensor is bruised (but not broken)
You can't win 'em all. Such is the case with the Curiosity rover, anyway, as diagnostics have revealed that its wind sensors have sustained damage. NASA engineers aren't fully sure what caused this minor setback to the otherwise successful landing, but hypothesize that stones might've been kicked up during the rocket-powered landing, which then struck the sensor's wiring. Fortunately, there's already someone on the job, as Javier Gomez-Elvira is investigating the damage with the intent of restoring the lost functionality. Another NASA scientist, Ashwin Vasavada, believes the issue is rather minor: "It degrades our ability to detect wind speed and direction when the wind is blowing from a particular direction, but we think we can work around that." The broken instrument was initially discovered as part of NASA's routine power-cycling of all instrumentation, so as to determine an overall bill of health for the rover. Now that Curiosity has earned its battle scars, it can hold its head high during its journey to Glenelg and Mount Sharp.
Curiosity landing video assembled from high-res images (video)
A new video has been compiled by Spaceflight101.com showing Curiosity's final minutes of terror in glorious HD (though a dearth of frames and lack of stabilization make it a bit herky-jerky). It's an assembly of all the high-res photos taken by the buggy on the way down to its now familiar perch, rolling at the not-exactly-HFR speed of 4 fps, but still trumping a previous low-res thumbnail version. It gives a much clearer, rover's-eye-view of the journey, starting with the heat shield ejection and finishing with the dusty, butterfly-like touchdown. Check it out below the break to see the precarious descent -- and don't forget your Dramamine. Update: An enterprising (and patient) individual, Dominic Muller, spent four straight days creating a frame interpolated version of the video, giving the choppy footage a beautiful, smooth new look. Check out his version below the original after the break -- blow it up to full screen HD, crank the sound and enjoy.
Curiosity rover warms up its laser with basaltic rock blast
Intrepid 6-wheeler Curiosity perhaps protested too much when it tweeted "Yes, I've got a laser beam attached to my head. I'm not ill tempered; I zapped a rock for science." NASA turned the rover's high-powered laser loose with 30 pulses of a million watts each, reducing a thin layer of the chosen stone, dubbed N165 "Coronation," to plasma. The resulting spectrum was then analyzed by the on-board "ChemCam" to determine its composition, and the US/French team who developed the system said it's working even better on Mars than it did on terra firma. The results are now being studied, but if we had a laser beam on another planet, we'd be firing it all over the place -- in the name of "science," of course.
Curiosity survives brain transplant, prepares for first drive
If you thought your OTA update took too long, how about four days? That's how long the Curiosity "brain transplant" took, and is now finally complete. This now means that the main computers have switched over from landing mode, to surface mode -- and thus we hope -- meaning the rover's good to go. That said, it's still a painfully slow process, with Curiosity's wheels likely remaining steadfastly motionless for at least another week -- and even then we're looking at a trip of just a few meters. When it comes to interplanetary travel, though, slow and steady definitely wins the race -- in the meantime, you can soak up the view.
Life on Mars: One week of Curiosity
Is there life on Mars? NASA's latest mission to the red planet might well answer that question, or perhaps the more pertinent question, was there life on Mars. At 10:02 AM EST on November 26th last year, the space agency's Mars Science Laboratory (to give the mission its full name) set off on its eight-month journey to the red planet. The most advanced equipment ever sent to the planet -- and the biggest-ever rover -- should allow exploration of some of the most interesting regions, over far larger distances than ever previously covered. On arrival, after negotiating a tricky landing, the mobile laboratory (that's Curiosity) will spend a Martian year (687 Earth days) analyzing rock samples and seeking evidence of conditions suitable for microbial life or -- we can live in hope -- actual evidence of the same. After the break, we take a look at some of the key events over the first seven days on the planet's surface.
NASA's Curiosity rover receives long-distance OTA update, 'brain transplant' on Mars
Think it's nifty when your carrier deigns to provide your smartphone with that long awaited OTA update? That's nothing. Over the weekend, NASA's Curiosity rover will be receiving its first long-distance OTA update -- all the way out there on Mars. The goal is to transition both redundant main computers from software suited for landing the vehicle to software optimized for surface exploration -- such as driving, obstacle avoidance and using the robotic arm. NASA calls it a "brain transplant" and points out that the software was actually uploaded during the flight from Earth. Now can someone please enable OTA downloads for the human brain? We'd really like to know kung fu. PR after the break.
Lego Curiosity Mars rover explores barren surface of Kennedy Space Center (video)
If you want to do what NASA just did, except in Lego form, then look no further. NXT builders Doug Moran and Will Gorman put together this amazing working Curiosity rover that can happily roll around plastic terrains, searching for the answer to Bowie's questions. Four of the six wheels are powered, enabling the gear to make 360 degree turns, while a fully working arm and mast are controlled separately. Of course, nothing we can say could compare to seeing it in the flesh plastic, so head on past the break to see it in action.
