  • NASA Loses Contact With MAVEN Mars Orbiter
    by BeauHD on 11/12/2025 at 7:00 am

    NASA has lost contact with its MAVEN Mars orbiter after it passed behind Mars. When it remerged from behind the planet, the spacecraft never resumed communications. SpaceNews reports: MAVEN launched in November 2013 and entered orbit around Mars in September 2014. The spacecraft's primary science mission is to study the planet's upper atmosphere and interactions with the solar wind, including how the atmosphere escapes into space. That is intended to help scientists understand how the planet changes from early in its history, when it had a much thicker atmosphere and was warm enough to support liquid water on its surface. MAVEN additionally serves as a communications relay, using a UHF antenna to link the Curiosity and Perseverance rovers on the Martian surface with the Deep Space Network. NASA's Mars Odyssey and Mars Reconnaissance Orbiter spacecraft also serve as communications relays for the rovers, but are both significantly older than MAVEN. The spacecraft has suffered some technical problems in the past, notably with its inertial measurement units (IMUs) used for navigation. In 2022, MAVEN switched to an "all-stellar" navigation system to minimize the use of the IMUs. MAVEN has enough propellant to maintain its orbit through at least the end of the decade. NASA's fiscal year 2026 budget proposal, though, zeroed out funding for MAVEN, which cost $22.6 million to operate in 2024. MAVEN was one of several missions "operating well past the end of prime mission" the proposal would terminate, despite MAVEN's role as a communications relay. Read more of this story at Slashdot.

  • ChatGPT Is Apple's Most Downloaded App of 2025
    by BeauHD on 11/12/2025 at 3:30 am

    An anonymous reader quotes a report from TechCrunch: Apple on Wednesday released its annual list of the most downloaded apps and games for the year. For the U.S. market, OpenAI's ChatGPT topped the ranks of free iPhone apps (not including games) with the most installs in 2025. The AI app was followed by Threads, Google, TikTok, WhatsApp, Instagram, YouTube, Google Maps, Gmail, and Google's Gemini. ChatGPT made it to No. 4 last year, but the top spot was taken by Chinese shopping app Temu. In 2023, the AI app didn't make the top-10 list despite being released on the iPhone in May 2023 to a strong debut. Read more of this story at Slashdot.

  • Operation Bluebird Wants To Relaunch 'Twitter' For a New Social Network
    by BeauHD on 11/12/2025 at 12:50 am

    A startup called Operation Bluebird is petitioning the US Patent and Trademark Office to strip X Corp of the "Twitter" and "tweet" trademarks, hoping to relaunch a new Twitter with the old brand, bird logo, and "town square" vibe. "The TWITTER and TWEET brands have been eradicated from X Corp.'s products, services, and marketing, effectively abandoning the storied brand, with no intention to resume use of the mark," the petition states. "The TWITTER bird was grounded." Ars Technica reports: If successful, two leaders of the group tell Ars, Operation Bluebird would launch a social network under the name Twitter.new, possibly as early as late next year. (Twitter.new has created a working prototype and is already inviting users to reserve handles.) Michael Peroff, an Illinois attorney and founder of Operation Bluebird, said that in the intervening years, more Twitter-like social media networks have sprung up or gained traction -- like Threads, Mastodon, and Bluesky. But none have the scale or brand recognition that Twitter did prior to Musk's takeover. "There certainly are alternatives," Peroff said. "I don't know that any of them at this point in time are at the scale that would make a difference in the national conversation, whereas a new Twitter really could." Similarly, Peroff's business partner, Stephen Coates, an attorney who formerly served as Twitter's general counsel, said that Operation Bluebird aims to recreate some of the magic that Twitter once had. "I remember some time ago, I've had celebrities react to my content on Twitter during the Super Bowl or events," he told Ars. "And we want that experience to come back, that whole town square, where we are all meshed in there." "Mere 'token use' won't be enough to reserve the mark," said Mark Lemley, a Stanford Law professor and expert in trademark law. "Or [X] could defend if it can show that it plans to go back to using Twitter. Consumers obviously still know the brand name. It seems weird to think someone else could grab the name when consumers still associate it with the ex-social media site of that name. But that's what the law says."

  • Google Faces Fines Over Google Play If It Doesn't Make More Concessions
    by BeauHD on 11/12/2025 at 12:10 am

    EU regulators say Google's Play Store changes still don't meet fairness rules and are preparing a potentially hefty 2026 fine unless Google makes deeper concessions. Reuters reports: Google Play has been in the European Commission's crosshairs since March, with regulators singling out technical restrictions preventing app developers from steering users to other channels for cheaper offers. Another issue is the service fee charged by Google for facilitating an app developer's initial acquisition of a new customer via Google Play which the regulator said goes beyond what is justified. Tweaks to Google Play announced in August to make it easier for app developers to direct customers to other channels and choose a fee model are still falling short, the people said, with the EU antitrust regulator viewing Apple's recent changes to its App Store as a benchmark. [...] Google can still offer to make more changes before regulators impose a fine, likely in the first quarter of the next year, the people said, adding that the timing of any sanction can still change. "We continue to work closely with the European Commission in its ongoing investigation but have serious concerns that further changes would put Android and Play users at risk of malware, scams and data theft. Unlike iOS, Android is already open by design," a Google spokesperson said. Read more of this story at Slashdot.

  • India Proposes Charging OpenAI, Google For Training AI On Copyrighted Content
    by BeauHD on 10/12/2025 at 11:30 pm

    An anonymous reader quotes a report from TechCrunch: On Tuesday, India's Department for Promotion of Industry and Internal Trade released a proposed framework that would give AI companies access to all copyrighted works for training in exchange for paying royalties to a new collecting body composed of rights-holding organizations, with payments then distributed to creators. The proposal argues that this "mandatory blanket license" would lower compliance costs for AI firms while ensuring that writers, musicians, artists, and other rights holders are compensated when their work is scraped to train commercial models. [...] The eight-member committee, formed by the Indian government in late April, argues the system would avoid years of legal uncertainty while ensuring creators are compensated from the outset. Defending the system, the committee says in a 125-page submission (PDF) that a blanket license "aims to provide an easy access to content for AI developers reduce transaction costs [and] ensure fair compensation for rightsholders," calling it the least burdensome way to manage large-scale AI training. The submission adds that the single collecting body would function as a "single window," eliminating the need for individual negotiations and enabling royalties to flow to both registered and unregistered creators.
