It's the first NASA-produced view from the surface of Mars at this resolution, and is stitched together from close to 900 exposures taken by cameras onboard Curiosity, revealing details of the landscape along the rover's route.
I'm sitting in on a NASA Jet propulsion laboratory teleconference for science journalists, with an update for the world on the Mars Curiosity rover's mission. Curiosity completes her "checkout" phase today. Including an "intermission" of 13 sols, and one remaining sol to inspect the rover's robotic arm, 26 sols have been devoted to so-called checkout duties. Today is sol 37. Rover is currently facing a Southeast direction. Temperatures on the rover are between 7 and 33 C. She has covered a little over a football field's distance on the surface of Mars. Ability to move the arm has been confirmed, and the ability of the rover to perform sampling is confirmed.
Curiosity has so far driven 109 meters from its original landing site, and engineers are driving her about 40 meters per sol. The first drilling into the surface of Mars is expected to occur about a month from now, following various surface activities (scraping rock surfaces, and so on).
Three speakers in the teleconference: Jennifer Trosper, JPL; Curiosity mission manager. Ralf Gellert, University of Guelph, in Guelph, Ontario, Canada; principal investigator for the Alpha Particle X-Ray Spectrometer instrument (or APXS) on Curiosity. Ken Edgett, Malin Space Science Systems, San Diego; principal investigator for the Mars Hand Lens Imager (or MAHLI) on Curiosity.
At the top of this blog post, the first Mars image of the day (larger size here):
At the Economist, Glenn Fleishmann writes about the 17 cameras on board the Curiosity rover on Mars. That's "seven more than any previous exploratory vehicle," he writes. They "store images in a raw, unprocessed format and initially beam back tiny thumbnails (which NASA uploads as they come in). The scientists working on different aspects of the mission meet daily to determine which of the thumbnails to download in higher resolution. The 'health and safety' of the rover takes priority. After the deliberations, which can last over an hour, instructions are dispatched to Mars." — Xeni
Snip from statement of Charlie Bolden, NASA Administrator, speaking via broadcast from the Curiosity Rover on the surface of Mars: "The knowledge we hope to gain from our observation and analysis of Gale Crater, will tell us much about the possibility of life on Mars as well as the past and future possibilities for our own planet. Curiosity will bring benefits to Earth and inspire a new generation of scientists and explorers, as it prepares the way for a human mission in the not too distant future." — Xeni
Glenn Fleishman writes in the Economist about how Curiosity sends messages home from Mars: "NASA'S Curiosity has the fastest modem on Mars. Since its only competition is an oldish bit of kit aboard Opportunity, one of two rovers dispatched in 2003, that is not saying much, at least in terms of what internet users on Earth have learned to expect. Curiosity's ability to capture images and other data easily outstrips its capacity to beam it all back home. Nonetheless, it delivers vastly more information from the red planet than any previous mission did." — Xeni
As Curiosity was landing safely on Mars, many of you noted that the Jet Propulsion Laboratory engineers orchestrating the whole thing were eating an awful lot of peanuts. In fact, each workstation boasted a little commemorative jar of peanuts. Seriously, what is up with all those peanuts?
Discovery News has an answer. And it's surprisingly interesting.
Turns out, this is a JPL-specific tradition, dating back to 1964, when the lab's funding was on the line after the Ranger program—unmanned missions to photograph the Moon—weren't living up to expectations. In fact, six Ranger missions in a row had failed.
This was the heritage leading up to Ranger 7. There was talk that JPL should be shut down, that a university-affiliated center couldn’t handle a rigorous spaceflight program. There were suggestions that the program had been sabotaged -- a worker found a small polyethylene bag with 14 screws and a lock washer in one of the sealed electronic modules in Ranger 7’s television subsystem.
Just before Ranger 7 launched to the moon on July 28, mission manager Harris Schurmeier handed out peanuts to ease tensions. He figured chewing or playing with them on the table would give his team something else to focus on.
[Video Link]. This parody music video debuted this week on a new YouTube channel called Satire, and mashes up LMFAO's hit “Sexy and I Know It” with the NASA Curiosity mission and abundant JPL-love.
"It comes complete with shout-outs to Carl Sagan and Neil deGrasse Tyson," reports the Washington Post, which dug into the story behind its creation. Half a million views so far, huh? Best NASA PSA ever.
What a beautiful video by Mark Rober, of NASA's Jet Propulsion Laboratory: "I was able to work on NASA JPL's Curiosity Mars Rover for 7 years. This video is an attempt to capture what it felt like to have 7 years of your life vindicated in the 7 minute landing. Honestly one of the coolest moments of my life so far.
This week the team at NASA’s Mars Science Laboratory finished "what amounted to a complete overhaul of the Curiosity Rover’s software," from 350 million miles away on another planet. Ben Cichy, Curiosity’s chief software engineer, explained to Wired News that the software required to help Curiosity land on the surface of Mars and the software it needs to drive around and avoid obstacles are different. The system "didn’t have enough memory to hold the software for both the landing mission and the surface mission, so the software had to be swapped out remotely after landing." The upgrade took four days, not unlike, say, Windows Server 8.
The slow data rates available for broadcasting images back to Earth and the team's familiarity with that family of sensors played a part, says [Ravine], but the biggest factor was the specifications being fixed as far back as 2004. Multi-shot panoramas will see the cameras deliver high-res images, he explains, but not the 3D movies Hollywood director James Cameron had wanted.
'There's a popular belief that projects like this are going to be very advanced but there are things that mitigate against that. These designs were proposed in 2004, and you don't get to propose one specification and then go off and develop something else. 2MP with 8GB of flash [memory] didn't sound too bad in 2004. But it doesn't compare well to what you get in an iPhone today.'
