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.
What time is it on Mars? There's a Mac app for that
Budding astronomers and NASA flight controllers need to know -- what time is it at the landing site of the Mars Science Laboratory (MSL) Opportunity rover? As we all know from watching the successful rover landing the other day, Macs are very popular at NASA's Jet Propulsion Laboratory. So it's not surprising that there's a Mac app available for determining the current time at various points on the red planet. The Mars24 Sunclock app is a Java application that displays a constantly updating clock in one window as well as a second window that displays a sunclock (a map of the Martian surface showing the parts of the planet in light and shadow), a solar system view showing where the various planets are in their orbits around the Sun, a local panorama from the Opportunity rover's current location, or an analemma. The app is surprisingly fun to use. The sunclock display also shows the spot on the Mars surface that is directly "under" the sun or Earth and the panorama display lets the flight controllers figure out when and where the sun is going to rise from the viewpoint of the rover. There's a constant display of how far away Mars is at the present time (1.685 AU or 156,630,535 miles), and how long it's going to take for signals from Earth or Mars to reach the other planet (right now, 14 minutes and 1 second). The only negative about this app is that most Mountain Lion machines don't have a Java virtual machine installed, and you'll be prompted to let OS X install it before you can run the app. There's also a security concern; getting the app to run on Mountain Lion at this time requires you to "allow applications downloaded from anywhere" just for the first launch, since this is an unsigned app and Gatekeeper throws a hissy fit when you try to run it. After that initial launch, you can switch your Gatekeeper settings back to the preferred "App Store & identified developers" option; the app has been whitelisted by the initial launch. Normally, you could use the workaround of right-clicking the app and choosing Open, then telling Gatekeeper to launch the app -- however as the NASA download page notes this does not work for this particular app. It reports as "damaged" unless Gatekeeper is in fully permissive mode for the first launch. [Thanks to reader Gregory for his note about Gatekeeper, which led us to check both the right-click and restored setting options.] Still, if you switch Gatekeeper to permissive mode for a moment, launch the app & then switch back, you can install Mars24 Sunclock and enjoy the feeling of being a Curiosity flight controller without the need for a mohawk haircut. Now if they could just make this an iOS app and give authorized people a way to "drive" the rover from home...

Macs abound at NASA/JPL Mars Curiosity mission control
For those of us who stayed up late last night to watch the streaming coverage of the Curiosity rover's landing on Mars, it was a treat to see the huge numbers of MacBooks, iPads, and even iPhones that were in the control room at NASA's Jet Propulsion Laboratory in Pasadena, California. The image above shows one of the EDL Ops (Entry, Descent and Landing Operations) engineers gazing intently at the screen of a MacBook Pro at incoming data. Other photos we've seen show a conference room full of engineers and scientists at JPL sitting around a table loaded with MacBook Pros with nary a Lenovo or Dell laptop in sight. Why the love of Macs? It's probably because OS X is the "Unix that works," the mainstream operating system that's built upon the BSD UNIX beloved by scientists and engineers (and is also certified by the Single UNIX Specification group as an Open Brand UNIX 03 product). Of course, the scientific and engineering community may not be thrilled with the recent shift away from bundling Apple-branded X11 with OS X in Mountain Lion, as that's often used to run legacy apps. The current X11 solution is the XQuartz open source project, which is heavily supported by Apple. Be sure to check back later; TUAW's Mel Martin is following up with a post about more reasons for all of this Apple love at JPL.

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.
NASA's Curiosity Mars landing successful, first pictures trickling in (video)
After "seven minutes of terror" involving guided entry, parachute and powered descent, and even a sky crane, NASA's Curiosity rover has successfully touched down on the surface of Mars. Better yet, the 2,000lbs (900kg) science lab has established communications with Earth and is sending back telemetry along with the first pictures of Gale crater. These initial grayscale images are only 256 x 256 pixels in size but show Curiosity's shadow on the Martian soil. Peek at our galley below and stay tuned for updates. Update: Hit the break to check out a video of all the "seven minutes of terror" highlights. %Gallery-161818%
Watch NASA's Curiosity rover touch down on Mars, live at 1:30AM EDT
You watched the launch, bit your nails over computer simulations and even played the game, and it all comes down to today: NASA's Curiosity rover is about to land on Mars. The $2.5 billion vehicle has been en route to the red planet for eight months, and in a few short hours will spend seven terrifying minutes blindly making its way to the Martian surface -- only to make NASA scientists wait another full seven before reporting on its success or failure. The rover is flying solo. That doesn't mean we can't be there in spirit, however: NASA TV will be broadcasting the event on Ustream, offering commentary from the minds behind the rover, as well as audio from mission control. The Curiosity Cam, which runs from 11:30PM until 2:00AM EDT and 3:30AM to 4:30AM EDT, will offer commentary from the scientists and engineers behind Curiosity, while a second feed (at NASA JPL Live, which runs from 11:30PM onward) will play audio from mission control. If all goes to plan, NASA will be able to share an image from Curiosity's navigation cameras, confirming its safe arrival on the Martian surface. Sounds like a hell of a show to us. Read on to view the Curiosity Cam right here or check out the source links below to prep your evening (or early morning) viewing for yourself. Let us know your own thoughts on Curiosity's landing in the comments. Update: Touchdown confirmed! The entire sequence went perfectly to plan, and rover Curiosity is now on the surface of Mars and sending telemetry data. Update: NASA's press conference is now happening live.
ESA team builds self-piloting rover in six months, tests it in Chilean desert
Chile's Atacama Desert might not be true Martian territory, but it's close enough for the European Space Agency's new rover. Built by a crack engineering team in just six months, the Seeker rover was created to autonomously roam 6 km of Mars-like terrain and trace its way back. The Seeker just wrapped up a two week gauntlet in the Chilean wasteland using ol' fashioned dead reckoning and stereoscopic vision to find its way, compiling a 3D map of its surroundings as it puttered along. The full-scale rover wandered the arid terrain on its lonesome until temperatures forced it to stop after trekking 5.1 km. The red planet won't welcome an ESA rover until 2018, but those jonesin' for news from Martian soil should keep their eyes peeled for Curiosity's August touchdown.
Curiosity rover to land in Mars's Gale Crater to look for life, finally answer Bowie's nagging questions
It's gotten its own photo shoot, some cool animation, and the interest of James Cameron -- and now Curiosity finally has a destination. NASA's pluckily-named Mars rover is set to land next to a mountain inside the red planet's 96-mile-wide Gale Crater. Curiosity is scheduled to touch down in August 2012 in search of life on the fourth rock from the sun. The crater, one of 60 suggested sites, was chosen due to its potential for a safe landing and the possibility of scientific discovery, thanks in part to nearby geographical formations that may have been created by water. Here's hoping it encounters some serious space oddities when it gets there.
