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.

Facebook’s next hardware product will be “smart” Ray-Ban glasses

Published

on

Enlarge / Don’t get too excited about how well these Ray-Bans go with Gitta Banko’s outfit—we don’t know what Facebook’s new smart glasses will look like, only that they’re made in partnership with the brand and its parent company.

In an earnings conference call on Wednesday, Facebook CEO Mark Zuckerberg told investors that the company’s next hardware launch will be “smart glasses” made in partnership with classic sunglasses vendor Ray-Ban.

Zuckerberg segued into the Ray-Ban announcement following a lengthy discussion of Facebook’s plans for Oculus Quest, its all-in-one virtual reality (VR) platform. Zuckerberg says that social media is the real “killer app” for VR, backing that up with data from Oculus Quest: “The most popular apps on Quest are social, which fits our original thesis [that] virtual reality will be a social platform.”

Zuckerberg intends the as yet unnamed smart glasses to be a stepping stone, not an end goal. He remained cagey about their actual purpose, saying only that the glasses “have their iconic form factor, and [let] you do some pretty neat things,” with no concrete details about what those “neat things” might be.

We do know that the glasses aren’t expected to have integrated display, thanks to reporting from The Verge on their initial announcement in September 2020. Without display capabilities, the Ray-Ban/Facebook glasses seem likely to fall in the same category as Amazon’s Echo Frames or Lucyd Lyte—a mostly normal-looking pair of sunglasses with integrated Bluetooth pairing and directional speakers that we reviewed in March.

Zuckerberg describes the smart glasses as a stepping stone toward not only virtual or augmented reality as we know it, but something he calls the metaverse. “So what is the metaverse? It’s a virtual environment [like] an embodied Internet that you’re inside of rather than just looking at. And we believe that this is going to be the successor to the mobile Internet.”

After warning that building his vision will require significant investment not only from Facebook itself but from its entire ecosystem of partners, he doubled down on its eventual importance, saying, “In addition to being the next chapter of the Internet, the metaverse is also going to be the next chapter for us as a company.”

Facebook set a new ad revenue record, despite Apple’s iOS privacy change

Published

on

Faebook CEO Mark Zuckerberg.

For months, Apple and Facebook waged a PR war (with threats of a legal one) over App Tracking Transparency, a change in recent versions of the iPhone’s iOS software that will often limit how advertising-focused apps and companies can monetize iPhone users.

Facebook’s original public predictions about App Tracking Transparency’s effect were apocalyptic. But even though App Tracking Transparency took effect during Facebook’s most recent quarter (Q2 of 2021) the company still posted huge ad revenue growth.

Facebook’s revenue, which is largely driven by the kinds of advertising that Apple’s iOS change undermines, grew 56 percent year-over-year in Q2, beating investor expectations. The company had 1.9 billion daily active users and 2.9 billion monthly active users. It earned $10.12 of revenue per user, on average.

This was the first earnings report Facebook has delivered on a quarter that should show any effects of App Tracking Transparency on the company’s bottom line. Fifty-six percent YOY growth certainly doesn’t look apocalyptic, but CFO David Wehner told investors to expect a less rosy story in the next quarter:

We continue to expect increased ad targeting headwinds in 2021 from regulatory and platform changes, notably the recent iOS updates, which we expect to have a greater impact in the third quarter compared to the second quarter.

Data on user opt-in rates for tracking has varied quite a bit. Some firms put the figure at just 4 percent, but others place opt-in rates as high as around 30 percent. And it likely depends on the app in question. In any case, users who opt in are definitely not the majority; most users are declining to be tracked when prompted. And each user who does is worth a lot less money to Facebook, which makes much of its money leveraging each user’s data to charge advertisers money to microtarget them and other users with similar attributes.

While Facebook’s initial messaging around App Tracking Transparency was combative and dire, Zuckerberg began changing his tune recently. He began to argue that the change could even be good for Facebook in some ways.

As for today, Zuckerberg is dedicating much of his time to describing his vision for the “metaverse,” which he has identified as the new direction for the company. He has described this vision as a mixed reality layer on our lives whereby people can interact with and socialize with one another virtually in new ways, crossing geographic barriers as if they were simply walking from room to room.

But Apple executives have also outlined a somewhat similar longterm vision, albeit with a very different approach in mind. By forcing Facebook to play by different ad-targeting rules, Apple has strengthened its position against the social media company in any coming battle over a future mixed reality computing landscape.

But at least for this quarter, Facebook doesn’t look like it is suffering too badly from the wound.

Google Play gets mandatory app privacy labels in April 2022

Published

on

In iOS 14, Apple added a “privacy” section to the app store, requiring app developers to list the data they collect and how they use it. Google—which was one of the biggest targets of Apple’s privacy nutrition labels and delayed app updates for months to avoid complying with the policy—is now aping the feature for Google Play.

Google posted a demo of what the Google Play “Data privacy & security” section will look like, and it contains everything you’d expect if you’ve looked at the App Store lately. There’s information on what data apps collect, whether or not the apps share the data with third parties, and how the data is stored. Developers can also explain what the data is used for and if data collection is required to use the app. The section also lists whether or not the collected data is encrypted, if the user can delete the data, and if the app follows Google’s “Families” policy (meaning all the usual COPPA stuff).

Google Play’s privacy section will be mandatory for all developers in April 2022, and starting in October, Google says developers can start populating information in the Google Play Console “for review.” Google also says that in April, all apps will need to supply a privacy policy, even if they don’t collect any data. Apps that don’t have an “approved” privacy section by April may have their app updates rejected or their app removed.

Google says, “Developers are responsible for providing accurate and complete information in their safety section.”

All of this information is basically just running on the honor system, and on iOS, developers have already been caught faking their privacy labels.
