Opportunity Mars rover goes to its last rest after extraordinary 14-year mission – TechCrunch

Published

Opportunity, one of two rovers sent to Mars in 2004, is officially offline for good, NASA and JPL officials announced today at a special press conference. “I declare the Opportunity mission as complete, and with it the Mars Exploration Rover mission as complete,” said NASA’s Thomas Zurbuchen.

The cause of Opportunity’s demise was a planet-scale sandstorm that obscured its solar panels too completely, and for too long, for its onboard power supply to survive and keep even its most elementary components running. It last communicated on June 10, 2018, but could easily have lasted a few months more as its batteries ran down — a sad picture to be sure. Even a rover designed for the harsh Martian climate can’t handle being trapped under a cake of dust at -100 degrees Celsius for long.

The team has been trying to reach it for months, employing a variety of increasingly desperate techniques to get the rover to at least respond; even if its memory had been wiped clean or instruments knocked out, it could be reprogrammed and refreshed to continue service if only they could set up a bit of radio rapport. But every attempt, from ordinary contact methods to “sweep and beep” ploys, was met with silence. The final transmission from mission control was last night.

Spirit and Opportunity, known together as the Mars Exploration Rovers mission, were launched individually in the summer of 2003 and touched down in January of 2004 — 15 years ago! — in different regions of the planet.

Each was equipped with a panoramic camera, a macro camera, spectrometers for identifying rocks and minerals and a little drill for taking samples. The goal was to operate for 90 days, traveling about 40 meters each day and ultimately covering about a kilometer. Both exceeded those goals by incredible amounts.

Spirit ended up traveling about 7.7 kilometers and lasting about 7 years. But Opportunity outshone its twin, going some 45 kilometers over 14 years — well over a marathon.

And of course both rovers contributed immensely to our knowledge of the Red Planet. It was experiments by these guys that really established a past when Mars not only had water, but bio-friendly liquid water that might have supported life.

Opportunity did a lot of science but always had time for a selfie, such as this one at the edge of Erebus Crater.

It’s always sad when a hard-working craft or robot finally shuts down for good, especially when it’s one that’s been as successful as “Oppy.” The Cassini probe went out in a blaze of glory, and Kepler has quietly gone to sleep. But ultimately these platforms are instruments of science and we should celebrate their extraordinary success as well as mourn their inevitable final days.

“Spirit and Opportunity may be gone, but they leave us a legacy — a new paradigm for solar system exploration,” said JPL head Michael Watkins. “That legacy continues not just in the Curiosity rover, which is currently operating healthily after about 2,300 days on the surface of Mars. But also in our new 2020 rover, which is under construction here at the Jet Propulsion Laboratory.”

“But Spirit and Opportunity did something more than that,” he continued. “They energized the public about the spirit of robotic Mars exploration. The infectious energy and electricity that this mission created was obvious to the public.”

Mars of course is not suddenly without a tenant. The Insight lander touched down last year and has been meticulously setting up its little laboratory and testing its systems. And the Mars 2020 rover is well on its way to launch. It’s a popular planet.

Perhaps some day we’ll scoop up these faithful servants and put them in a Martian museum. For now, let’s look forward to the next mission.

Lenovo gives up on its dream of Android gaming phones

Published

on

Android manufacturers occasionally try to push this idea of a “gaming smartphone”—usually, these companies try to extend the “PC gamer” design motif to smartphones, with RGB LEDs and aggressive marketing. Since Android games are mostly casual pay-to-win tap fests, though, we often have to ask, does anyone want a gaming smartphone? If you’re Lenovo, the answer is apparently “no,” as Android Authority reports Lenovo is killing the “Legion” gaming phone business.

The site quoted a Lenovo spokesperson:

Lenovo is discontinuing its Android-based Legion mobile gaming phones as part of a wider business transformation and gaming portfolio consolidation. As a leader in gaming devices and solutions, Lenovo is committed to advancing the gaming category across form factors, as well as focusing on where it can bring the most value to the global gaming community.

While gaming phones often seem like a product without a market, we are a bit sad to see Lenovo pack it in since the Lenovo Legion Phone Duel 2 was the most extreme version of the idea. That phone had what must have been the most powerful cooling system ever fitted to an Android phone, with two internal cooling fans, copper heat pipes, and loads of graphite pads. While most passively cooled Android phones would quickly throttle in a graphics-intensive game, this was one of the rare phones with what looked like sustainable cooling. Of course, it didn’t fit into a normal smartphone body—the phone’s center (in landscape) was about twice as thick as normal, but it was a neat product.

Lenovo packed a lot of other interesting additions into its gaming phone: it had six touch-sensitive buttons on the back: four on the top edge of the phone, replicating L1/R1 L2/R2 design of console controllers, and two on the back of the phone for your middle fingers. It also had two USB-C ports: one in the usual location, but since that would be blocked during landscape gaming, a second port was on the side of the phone, so it would point downward during landscape gaming. You could charge from either port, but you could also charge with both ports simultaneously, which Lenovo called 90 W “ultra-fast double charging.” The included charger had two USB ports on it.

Lenovo was right to focus on cooling because while PC gaming computers can prove their worth with premium parts, there’s no such thing as “better than flagship” parts for smartphones. The Duel 2 had the same Snapdragon 888 SoC as every other flagship device, but at least it could run without throttling. The other things that exist for PC gaming and don’t exist for Android are games, or at least games that would encourage buying enthusiast-grade hardware. Even if you found a faster-than-normal phone, there would be few apps that could take advantage of it other than an emulator.

After two years, Autodesk Maya and AutoCAD become Apple Silicon-native

Published

on

It has been two years and four months since the first Apple Silicon Mac hit the market, and now Autodesk has finally updated some of its massively popular professional applications (AutoCAD and Maya) to run natively on M1 and M2 chips.

The availability of AutoCAD for Mac 2024 was announced in a blog post on Autodesk’s website on March 28. Like other major AutoCAD updates, it adds new features like expanded automation tools and easier workflows, but the announcement that “for the first time, AutoCAD for Mac 2024 and AutoCAD LT for Mac 2024 now run natively on both Intel and Apple Silicon architectures, including M1 and M2 chips in the M-series chips” is clearly the headlining feature.

Autodesk claims that Apple Silicon support “can increase overall performance by up to two times” compared to the 2023 version of AutoCAD.

AutoCAD is widely used in various industries and trades, including architecture, city planning, and industrial design.

A day later, on March 29, Autodesk revealed the 2024 update for Maya, its 3D modeling software chiefly used in game development, film production, and visual effects. Maya 2024 brings native Apple Silicon support in addition to a slew of new features, including the LookDevX material editor, Hydra support, and so on.

But in contrast to many other makers of widespread professional software in similar industries, such as Adobe and Unity, Autodesk’s efforts to support Apple Silicon—which were announced two years ago—have been ongoing for an interminably long time. Even open source Maya competitor Blender beat Autodesk to the punch.

The Intel versions of both Maya and AutoCAD worked OK in Rosetta, but some Mac users have become understandably frustrated over the past couple of years, and Autodesk never really clarified why it was taking so long.

Nonetheless, it’s here now. We were able to download Maya 2024 for no additional charge on an existing subscription and confirmed that it is running as an Apple Silicon app on an M2 Max-equipped MacBook Pro.

Apple will host WWDC 2023 in person and online June 5 through June 9

Apple will host its 34th annual Worldwide Developers Conference at its Cupertino, California, headquarters from Monday, June 5 through Friday, June 9, the company announced on Wednesday.

The conference will kick off with “a special all-day event,” inclusive of the customary keynote presentation and the platform State of the Union talks. The language on Apple’s website suggests that like last year, some or all of those will be presented in prerecorded video form rather than as a live on-stage presentation.

After that first day, Apple will likely host various panels on how developers can work with the company’s developer toolkits and APIs to support new and old features across the various Apple platforms.

Members of Apple’s developer program who want to attend essentially sign up for a lottery to see if they are chosen, as the event cannot host enough people in person to meet demand. That said, the entire conference will also be available online to developers. In either case, the conference is free.

The main purpose of the WWDC keynote each year is usually to announce and explain new features coming to the next versions of Apple’s various platform operating systems—in this case, iOS 17, iPadOS 17, tvOS 17, watchOS 10, and macOS 14.

That’s almost sure to be the case this year as well. Sometimes Apple announces new hardware or consumer services at WWDC, too—but not always.

There have been many reports from reliable sources over the past few months that Apple hopes to provide a first look at its long-delayed mixed-reality headset and related software at this WWDC. If so, we expect that to be a big part of the keynote.

Even if that’s the case, the headset probably won’t be released this June. It’s much more likely that Apple will outline what to expect from a release further down the road (possibly in September alongside the new flagship iPhones, but maybe even later) so that developers can begin work creating applications, games, and experiences for the new platform.

WWDC also coincides with Apple’s Swift Student Challenge, a coding competition for students. The deadline to apply for that challenge is April 19.

Ars Technica will cover the announcements as they come in on the day of the keynote.
