The "technology building blocks" for space solar are already available, reports Clean Technica. "It's just a matter of scaling, systems integration, and adjustments for space-hardiness."

And several groups are looking at it — including the U.S. Space Force To help push costs down, the California Institute of Technology has proposed a sandwich-type solar module that integrates solar harvesting along with conversion to a radio frequency into one compact package, accompanied by a built-in antenna. Last month researchers at the school wrapped up a months-long, in-space test of different types of solar cells. Another approach is illustrated by the Michigan startup Virtus Solis, an industry partner of the University of Bristol. Last June the company and the school received £3.3 million in funding from the UK Net Zero Innovation program, for developing an open-source model for testing the performance of large, centralized antennas in space. "The concept depends upon the use of gigascale antenna arrays capable of delivering over 2GW of power from space onto similar gigascale antenna arrays either at sea or on the ground," the school explained.

As for how such a thing would be launched into space, that's where the U.S. Space Force comes in. Last August, the Space Force awarded a small business contract to the U.S. startup Orbital Composites. The company is tasked with the mission of developing its patented "quantum antenna" and in-space fabrication tools for secure communications in space applications, including space-to-space as well as space-to-Earth and vice versa. The basic idea is to let 3D printing doing much of the work in space. According to Orbital, in-space fabrication would save more than 100 times the cost of applying conventional fabrication methods to large-scale orbiting antennas. "By harnessing the potential of In-Space Servicing, Assembly, and Manufacturing (ISAM), the company eyes the prospect of creating significantly larger space antennas," Orbital Composites explains. "By fabricating antennas in space, larger and more complex designs are possible that eliminate the constraints of launch and rocket fairings...."

If you're guessing that a hookup between Virtus and Orbital is in the works, that's a good guess. On February 1, at the SpaceCOM conference in Orlando, Florida, Virtus Solis let slip that it is working with Orbital Composites on a space solar pilot project. If all goes according to plan, the project will be up and running in 2027, deploying Virtus's robot-enabled fabrication system with Orbital's 3D printing. As of this writing the two companies have not posted details, but Space News picked up the thread. "The 2027 mission is designed to showcase critical power-generation technologies including in-space assembly of solar panels and transmission of more than one kilowatt to Earth," Space News explained. "The news release calls the 2027 mission "a precursor to large-scale commercial megawatt-class solar installations in space by 2030...."

To be clear, Orbital's press release about its new Space Force quantum antenna contract does not mention anything in particular about space solar. However, the pieces of the puzzle fit. Along with the Virtus and Grumman connections, in October of 2022 Orbital won a small business contract through SpaceWERX, the Space Force's innovative technologies funding arm, to explore the capabilities of ISAM systems.
"SpaceWERX comes under the umbrella of the U.S. Air Force's AFWERX innovation branch, which has developed a program called SSPIDR, short for Space Solar Power Incremental Demonstrations and Research Project," the article points out. (While Virtus believes most space-based solar power systems could deliver megawatt hours of electricity at prices comparable to today's market.)

"When Satya Nadella replaced Steve Ballmer as Microsoft CEO in February 2014, the software company was mired in mediocrity," writes CNBC, noting that Microsoft's market cap was just over $300 billion.

"A decade later, Microsoft's valuation has swelled tenfold, to $3.06 trillion, making it the world's most valuable public company, ahead of Apple." (And it's also "firmly entrenched as a leader in key areas, such as cloud and artificial intelligence.") As Nadella marks his 10-year anniversary at the helm, he's widely praised across the tech industry for changing the narrative at Microsoft, whose stock fell 30% during Ballmer's 14 years at the top. In that era, the company was squelched by Google in web search and mobile and was completely left behind in social media. Many tech industry analysts and investors would say that, thanks largely to Nadella, Microsoft is now set up to be a powerhouse for the foreseeable future...

In a 2020 interview, Pat Gelsinger, then CEO of VMware, said offering his company's software on Microsoft's Azure cloud was akin to a "Middle East peace treaty...." In the Nadella age, Microsoft has also contributed to open-source projects, released software under open-source licenses and released a version of its Teams communications app for Linux... In 2018, Nadella came to believe in the idea of buying GitHub just 20 minutes after Nat Friedman, then a Microsoft corporate vice president, started pitching him on it. Right away, Nadella suggested that Friedman become GitHub's new CEO, Friedman said. Microsoft paid $7.5 billion for the code-storage startup...

While Nadella may not bring as much entertainment value, he's proven to be more effective than Ballmer when it comes to dealmaking. In addition to GitHub, Nadella has made pricey acquisitions such as LinkedIn, Minecraft parent Mojang, and Nuance Communications that have contributed to Microsoft's top line. More recently, Nadella helped Microsoft land the $75 billion acquisition of game publisher Activision Blizzard...
The article also adds that Microsoft "looked at buying TikTok in the U.S. in 2020, but nothing came of those discussions."

An anonymous Slashdot reader shared this report from the San Francisco Chronicle's senior political writer: The next House member representing Silicon Valley wants to change a key piece of federal law that shields internet companies like X, Facebook and Snapchat from lawsuits over content their users post. That protection is considered the lifeblood of social media.

The top eight Democratic candidates vying to succeed Democratic Rep. Anna Eshoo in her very blue district agree that something has to change with Section 230 of the Communications Decency Act, which was created in 1996, back when lawmakers shied away from doing anything that could limit the growth of the industry. Their unanimity is a sign that Eshoo's successor won't be a tool for the hometown industry. At least not on this issue. The challenge is what to do next. Whoever is elected, their actions as the voice of Silicon Valley will carry outsize weight in Congress. They can lead the charge to actually do something to clean up the bile on social media...

The good news is that they will have bipartisan support to address the bile and disinformation online. The bad news is that finding the right solution will still be hard.

The non-profit Linux Foundation Energy hopes to develop energy-sector solutions (including standards, specifications, and software) supporting rapid decarbonization by collaborating with industry stakeholders.

And now they're involved in a new partnership with America's Joint Office of Energy — which facilitates collaboration between the federal Department of Energy and its Department of Transportation. The partnership's goal? To "build open-source software tools to support communications between EV charging infrastructure and other systems."

The Buildout reports: The partnership and effort — known as "Project EVerest" — is part of the administration's full-court press to improve the charging experience for EV owners as the industry's nationwide buildout hits full stride. "Project EVerest will be a game changer for reliability and interoperability for EV charging," Gabe Klein, executive director of the administration's Joint Office of Energy and Transportation, said yesterday in a post on social media....

Administration officials said that a key driver of the move to institute broad standards for software is to move beyond an era of unreliable and disparate EV charging services throughout the U.S. Dr. K. Shankari, a principal software architect at the Joint Office of Energy and Transportation, said that local and state governments now working to build out EV charging infrastructure could include a requirement that bidding contractors adhere to Project EVerest standards. That, in turn, could have a profound impact on providers of EV charging stations and services by requiring them to adapt to open source standards or lose the opportunity to bid on public projects. Charging availability and reliability are consistently mentioned as key turnoffs for potential EV buyers who want the infrastructure to be ready, easy, and consistent to use before making the move away from gas cars.

Specifically, the new project will aim to create what's known as an open source reference implementation for EV charging infrastructure — a set of standards that will be open to developers who are building applications and back-end software... And, because the software will be available for any company, organization, or developer to use, it will allow the creation of new EV infrastructure software at all levels without software writers having to start from scratch. "LF Energy exists to build the shared technology investment that the entire industry can build on top of," said Alex Thompson of LF Energy during the web conference. "You don't want to be re-inventing the wheel."
The tools will help communication between charging stations (and adjacent chargers), as well as vehicles and batteries, user interfaces and mobile devices, and even backend payment systems or power grids. An announcement from the Joint Office of Energy and Transportation says this software stack "will reduce instances of incompatibility resulting from proprietary systems, ultimately making charging more reliable for EV drivers." "The Joint Office is paving the way for innovation by partnering with an open-source foundation to address the needs of industry and consumers with technical tools that support reliable, safe and interoperable EV charging," said Sarah Hipel, Standards and Reliability Program Manager at the Joint Office.... With this collaborative development model, EVerest will speed up the adoption of EVs and decarbonization of transportation in the United States by accelerating charger development and deployment, increase customizability, and ensure high levels of security for the nation's growing network.
Linux Foundation Energy adds that reliable charging "is key to ensuring that anyone can confidently choose to ride or drive electric," predicting it will increase customizability for different use cases while offering long-term maintainability, avoiding vendor-lock in, and ensuring high levels of security. This is a pioneering example of the federal government collaborating to deploy code into an open source project...

"The EVerest project has been demonstrated in pilots around the world to make EV charging far more reliable and reduces the friction and frustration EV drivers have experienced when a charger fails to work or is not continually maintained," said LF Energy Executive Director Alex Thornton. "We look forward to partnering with the Joint Office to create a robust firmware stack that will stand the test of time, and be maintained by an active and growing global community to ensure the nation's charging infrastructure meets the needs of a growing fleet of electric vehicles today and into the future."

In the behavior of tech companies, the Atlantic's executive editor warns us about "a clear and coherent ideology that is seldom called out for what it is: authoritarian technocracy. As the most powerful companies in Silicon Valley have matured, this ideology has only grown stronger, more self-righteous, more delusional, and — in the face of rising criticism — more aggrieved." The new technocrats are ostentatious in their use of language that appeals to Enlightenment values — reason, progress, freedom — but in fact they are leading an antidemocratic, illiberal movement. Many of them profess unconditional support for free speech, but are vindictive toward those who say things that do not flatter them. They tend to hold eccentric beliefs.... above all, that their power should be unconstrained. The systems they've built or are building — to rewire communications, remake human social networks, insinuate artificial intelligence into daily life, and more — impose these beliefs on the population, which is neither consulted nor, usually, meaningfully informed. All this, and they still attempt to perpetuate the absurd myth that they are the swashbuckling underdogs.
The article calls out Marc Andreessen's Techno-Optimist Manifesto for saying "We believe in adventure... rebelling against the status quo, mapping uncharted territory, conquering dragons, and bringing home the spoils for our community..." (The Atlantic concludes Andreessen's position "serves only to absolve him and the other Silicon Valley giants of any moral or civic duty to do anything but make new things that will enrich them, without consideration of the social costs, or of history.")

The article notes that Andreessen "also identifies a list of enemies and 'zombie ideas' that he calls upon his followers to defeat, among them 'institutions' and 'tradition.'" But the Atlantic makes a broader critique not just of Andreessen but of other Silicon Valley elites. "The world that they have brought into being over the past two decades is unquestionably a world of reckless social engineering, without consequence for its architects, who foist their own abstract theories and luxury beliefs on all of us..." None of this happens without the underlying technocratic philosophy of inevitability — that is, the idea that if you can build something new, you must. "In a properly functioning world, I think this should be a project of governments," [Sam] Altman told my colleague Ross Andersen last year, referring to OpenAI's attempts to develop artificial general intelligence. But Altman was going to keep building it himself anyway. Or, as Zuckerberg put it to The New Yorker many years ago: "Isn't it, like, inevitable that there would be a huge social network of people? ... If we didn't do this someone else would have done it."
The article includes this damning chat log from a 2004 conversation Zuckerberg had with a friend:

Zuckerberg: If you ever need info about anyone at Harvard.
Zuckerberg: Just ask.
Zuckerberg: I have over 4,000 emails, pictures, addresses, SNS
Friend: What? How'd you manage that one?
Zuckerberg: People just submitted it.
Zuckerberg: I don't know why.
Zuckerberg: They "trust me"
Zuckerberg: Dumb fucks.'

But the article also reminds us that in Facebook's early days, "Zuckerberg listed 'revolutions' among his interests." The main dangers of authoritarian technocracy are not at this point political, at least not in the traditional sense. Still, a select few already have authoritarian control, more or less, to establish the digital world's rules and cultural norms, which can be as potent as political power...

[I]n recent years, it has become clear that regulation is needed, not least because the rise of technocracy proves that Silicon Valley's leaders simply will not act in the public's best interest. Much should be done to protect children from the hazards of social media, and to break up monopolies and oligopolies that damage society, and more. At the same time, I believe that regulation alone will not be enough to meaningfully address the cultural rot that the new technocrats are spreading.... We do not have to live in the world the new technocrats are designing for us. We do not have to acquiesce to their growing project of dehumanization and data mining. Each of us has agency.

No more "build it because we can." No more algorithmic feedbags. No more infrastructure designed to make the people less powerful and the powerful more controlling. Every day we vote with our attention; it is precious, and desperately wanted by those who will use it against us for their own profit and political goals. Don't let them.

• The article specifically recommends "challenging existing norms about the use of apps and YouTube in classrooms, the ubiquity of smartphones in adolescent hands, and widespread disregard for individual privacy. People who believe that we all deserve better will need to step up to lead such efforts."
• "Universities should reclaim their proper standing as leaders in developing world-changing technologies for the good of humankind. (Harvard, Stanford, and MIT could invest in creating a consortium for such an effort — their endowments are worth roughly $110 billion combined.)"

An anonymous reader quotes a report from Ars Technica: The Federal Communications Commission plans to vote on making the use of AI-generated voices in robocalls illegal. The FCC said that AI-generated voices in robocalls have "escalated during the last few years" and have "the potential to confuse consumers with misinformation by imitating the voices of celebrities, political candidates, and close family members." FCC Chairwoman Jessica Rosenworcel's proposed Declaratory Ruling would rule that "calls made with AI-generated voices are 'artificial' voices under the Telephone Consumer Protection Act (TCPA), which would make voice cloning technology used in common robocalls scams targeting consumers illegal," the commission announced yesterday. Commissioners reportedly will vote on the proposal in the coming weeks.

The TCPA, a 1991 US law, bans the use of artificial or prerecorded voices in most non-emergency calls "without the prior express consent of the called party." The FCC is responsible for writing rules to implement the law, which is punishable with fines. As the FCC noted yesterday, the TCPA "restricts the making of telemarketing calls and the use of automatic telephone dialing systems and artificial or prerecorded voice messages." Telemarketers are required "to obtain prior express written consent from consumers before robocalling them. If successfully enacted, this Declaratory Ruling would ensure AI-generated voice calls are also held to those same standards."

Rosenworcel said her proposed ruling will "recognize this emerging technology as illegal under existing law, giving our partners at State Attorneys General offices across the country new tools they can use to crack down on these scams and protect consumers. "AI-generated voice cloning and images are already sowing confusion by tricking consumers into thinking scams and frauds are legitimate," Rosenworcel said. "No matter what celebrity or politician you favor, or what your relationship is with your kin when they call for help, it is possible we could all be a target of these faked calls."

SpaceX revealed that it's delivering over 42 petabytes of data for customers per day, according to engineer Travis Brashears. "We're passing over terabits per second [of data] every day across 9,000 lasers," Brashears said today at SPIE Photonics West, an event in San Francisco focused on the latest advancements in optics and light. "We actually serve over lasers all of our users on Starlink at a given time in like a two-hour window." PCMag reports: Although Starlink uses radio waves to beam high-speed internet to customers, SpaceX has also been outfitting the company's satellites with a "laser link" system to help drive down latency and improve the system's global coverage. The lasers, which can sustain a 100Gbps connection per link, are especially crucial to helping the satellites fetch data when no SpaceX ground station is near, like over the ocean or Antarctic. Instead, the satellite can transmit the data to and from another Starlink satellite in Earth's orbit, forming a mesh network in space.

Tuesday's talk from Brashears revealed the laser system is quite robust, even as the equipment is flying onboard thousands of Starlink satellites constantly circling the Earth. Despite the technical challenges, the company has achieved a laser "link uptime" at over 99%. The satellites are constantly forming laser links, resulting in about 266,141 "laser acquisitions" per day, according to Brashears' presentation. But in some cases, the links can also be maintained for weeks at a time, and even reach transmission rates at up to 200Gbps.

Brashears also said Starlink's laser system was able to connect two satellites over 5,400 kilometers (3,355 miles) apart. The link was so long "it cut down through the atmosphere, all the way down to 30 kilometers above the surface of the Earth," he said, before the connection broke. "Another really fun fact is that we held a link all the way down to 122 kilometers while we were de-orbiting a satellite," he said. "And we were able to downstream the video." During his presentation, Brashears also showed a slide depicting how the laser system can deliver data to a Starlink dish in Antarctica through about seven different paths. "We can dynamically change those routes within milliseconds. So as long as we have some path to the ground [station], you're going to have 99.99% uptime. That's why it's important to get as many nodes up there as possible," he added.

AmiMoJo writes: Apple has attacked proposals for the UK government to pre-approve new security features introduced by tech firms. Under the proposed amendments to existing laws, if the UK Home Office declined an update, it then could not be released in any other country, and the public would not be informed. The government is seeking to update the Investigatory Powers Act (IPA) 2016. The Home Office said it supported privacy-focused tech but added that it also had to keep the country safe.

A government spokesperson said: "We have always been clear that we support technological innovation and private and secure communications technologies, including end-to-end encryption, but this cannot come at a cost to public safety." The proposed changes will be debated in the House of Lords tomorrow. Apple says it is an "unprecedented overreach" by the UK government. "We're deeply concerned the proposed amendments to the Investigatory Powers Act (IPA) now before Parliament place users' privacy and security at risk," said Apple in a statement. "It's an unprecedented overreach by the government and, if enacted, the UK could attempt to secretly veto new user protections globally preventing us from ever offering them to customers."

T-Mobile has tweaked its terms of service for its home broadband users to add a new clause: If you are a heavy internet user that passes 1.2TB of data in a monthly billing cycle, you may have your speeds slowed in "times of congestion" or when there is a lot of pressure on the network. CNET: As spotted by The Mobile Report, the change went into effect on Jan. 18. In its updated terms, the carrier says that these users "will be prioritized last on the network" in congestion situations, which could mean painfully slow speeds for however long the congestion persists. T-Mobile does note that since its Home Internet service is available only in "limited areas" and intended to be used in a "stationary" setting, as opposed to a phone that could be in a busy place like a packed stadium, "these customers should be less likely to notice congestion in general."

The Wall Street Journal reports that "a motley crew of AM radio advocates," including conservative talk show hosts and federal emergency officials, are lobbying Congress to stop carmakers from dropping AM radio from new vehicles: Lawmakers say most car companies are noncommittal about the future of AM tuners in vehicles, so they want to require them by law to keep making cars with free AM radio. Supporters argue it is a critical piece of the emergency communication network, while the automakers say Americans have plenty of other ways, including their phones, to receive alerts and information. The legislation has united lawmakers who ordinarily want nothing to do with one another. Sens. Ted Cruz (R., Texas) and Ed Markey (D., Mass.) are leading the Senate effort, and on the House side, Speaker Mike Johnson — himself a former conservative talk radio host in Louisiana — and progressive "squad" member Rep. Rashida Tlaib of Michigan are among about 200 co-sponsors...

A spring 2023 Nielsen survey, the most recent one available, showed that AM radio reaches about 78 million Americans every month. That is down from nearly 107 million in the spring of 2016, one of the earliest periods for which Nielsen has data... Automakers say the rise of electric vehicles is driving the shift away from AM, because onboard electronics create interference with AM radio signals — a phenomenon that "makes the already fuzzy analog AM radio frequency basically unlistenable," according to the Alliance for Automotive Innovation, a car-industry trade group. Shielding cables and components to reduce interference would cost carmakers $3.8 billion over seven years, the group estimates.

Markey and other lawmakers say they want to preserve AM radio because of its role in emergency communications. The Federal Emergency Management Agency says that more than 75 radio stations, most of which operate on the AM band and cover at least 90% of the U.S. population, are equipped with backup communications equipment and generators that allow them to continue broadcasting information to the public during and after an emergency. Seven former FEMA administrators urged Congress in a letter last year to seek assurances from automakers that they would keep broadcast radio available. The companies' noncommittal response spurred legislation, lawmakers said.

Automakers increasingly want to put radio and other car features "behind a paywall," Markey said in an interview. "They see this as another profit center for them when the American driving public has seen it as a safety resource for them and their families...." He compared the auto industry's resistance to the bill to previous opposition to government mandates like seat belts and air bags. "Leaving safety decisions to the auto industry is very dangerous," Markey said.
Lawmakers have heard from over 400,000 AM radio supporters, according to the president of the National Association of Broadcasters.

But the article also cites an executive at the Consumer Technology Association, who says automakers and tech advocacy groups have told lawmakers that requiring AM radio "would be "inconsistent with the principles of a free market.... It's strange that Congress is focused on a 100-year-old technology."

The National Security Agency buys certain logs related to Americans' domestic internet activities from commercial data brokers, according to an unclassified letter by the agency. The New York Times: The letter [PDF], addressed to a Democratic senator and obtained by The New York Times, offered few details about the nature of the data other than to stress that it did not include the content of internet communications. Still, the revelation is the latest disclosure to bring to the fore a legal gray zone: Intelligence and law enforcement agencies sometimes purchase potentially sensitive and revealing domestic data from brokers that would require a court order to acquire directly.

It comes as the Federal Trade Commission has started cracking down on companies that trade in personal location data that was gathered from smartphone apps and sold without people's knowledge and consent about where it would end up and for what purpose it would be used. In a letter to the director of national intelligence dated Thursday, the senator, Ron Wyden, Democrat of Oregon, argued that "internet metadata" -- logs showing when two computers have communicated, but not the content of any message -- "can be equally sensitive" as the location data the F.T.C. is targeting. He urged intelligence agencies to stop buying internet data about Americans if it was not collected under the standard the F.T.C. has laid out for location records. "The U.S. government should not be funding and legitimizing a shady industry whose flagrant violations of Americans' privacy are not just unethical, but illegal," Mr. Wyden wrote.

AT&T, Google and Vodafone are investing a total of $206.5 million in AST SpaceMobile, a satellite manufacturer that plans to be the first space-based network to connect standard mobile phones at broadband speeds. Fierce Wireless reports: AST SpaceMobile claims it invented the space-based direct-to-device market, with a patented design facilitating broadband connectivity directly to standard, unmodified cellular devices. In a press release, AST SpaceMobile said the investment from the likes of AT&T, Google and Vodafone underscores confidence in the company's technology and leadership position in the emerging space-based cellular D2D market. There's the potential to offer connectivity to 5.5 billion cellular devices when they're out of coverage.

Bolstering the case for AST SpaceMobile, Vodafone and AT&T placed purchase orders -- for an undisclosed amount -- for network equipment to support their planned commercial services. In addition, Google and AST SpaceMobile agreed to collaborate on product development, testing and implementation plans for SpaceMobile network connectivity on Android and related devices. AST SpaceMobile boasts agreements and understandings with more than 40 mobile network operators globally. However, it's far from alone in the D2D space. Apple/Globalstar, T-Mobile/SpaceX, Bullitt and Lynk Global are among the others.

"Bell Labs, the historic headwaters of so many inventions that now define our digital age, is closing in Murray Hill," writes journalism professor Jeff Jarvis (in an op-ed for New Jersey's Star-Ledger newspaper).

"The Labs should be preserved as a historic site and more." I propose that Bell Labs be opened to the public as a museum and school of the internet.

The internet would not be possible without the technologies forged at Bell Labs: the transistor, the laser, information theory, Unix, communications satellites, fiber optics, advances in chip design, cellular phones, compression, microphones, talkies, the first digital art, and artificial intelligence — not to mention, of course, many advances in networks and the telephone, including the precursor to the device we all carry and communicate with today: the Picturephone, displayed as a futuristic fantasy at the 1964 World's Fair.

There is no museum of the internet. Silicon Valley has its Computer History Museum. New York has museums for television and the moving image. Massachusetts boasts a charming Museum of Printing. Search Google for a museum of the internet and you'll find amusing digital artifacts, but nowhere to immerse oneself in and study this immensely impactful institution in society.

Where better to house a museum devoted to the internet than New Jersey, home not only of Bell Labs but also at one time the headquarters of the communications empire, AT&T, our Ma Bell...? The old Bell Labs could be more than a museum, preserving and explaining the advances that led to the internet. It could be a school... Imagine if Bell Labs were a place where scholars and students in many disciplines — technologies, yes, but also anthropology, sociology, psychology, history, ethics, economics, community studies, design — could gather to teach and learn, discuss and research.
The text of Jarvis's piece is behind subscription walls, but has apparently been re-published on X by innovation theorist John Nosta.

In one of the most interesting passages, Jarvis remembers visiting Bell Labs in 1995. "The halls were haunted with genius: lab after lab with benches and blackboards and history within. We must not lose that history."

"Good news..." NASA posted Saturday night on X. "We've reestablished contact with the Mars Helicopter..."

After a two-day communications blackout, NASA had instructed its Perseverance Mars rover "to perform long-duration listening sessions for Ingenuity's signal" — and apparently they did the trick. "The team is reviewing the new data to better understand the unexpected comms dropout" during the helicopter's record-breaking 72nd flight.

Slashdot reader Thelasko shared this report from NPR: Communications broke down on Thursday, when the little autonomous rotorcraft was sent on a "quick pop-up vertical flight," to test its systems after an unplanned early landing during its previous flight, the agency said in a status update on Friday night. The Perseverance rover, which relays data between the helicopter and Earth during the flights, showed that Ingenuity climbed to its assigned maximum altitude of 40 feet, NASA said.

During its planned descent, the helicopter and rover stopped communicating with each other...
Even before it came back online, RockDoctor (Slashdot reader #15,477) pointed out that the Mars copter has done this before. "Batteries dieing, resulting in a communications re-set, If I remember correctly."

Space.com also noted additional alternatives: "Perseverance is currently out of line-of-sight with Ingenuity, but the team could consider driving closer for a visual inspection," NASA's Jet Propulsion Laboratory in Southern California, which manages both robots' missions, said via X on Friday.

Ingenuity has stayed aloft for more than 128 minutes and covered a total of 11 miles (17.7 kilometers) during its 72 Mars flights, according to the mission's flight log.

A resident in Virginia has urged the Federal Communications Commission to reconsider canceling $886 million in federal funding for SpaceX's Starlink system. But rival satellite company Viasat has gone out of its way to oppose the citizen-led petition.ÂPCMag: On Jan. 1, the FCC received a petition from the Virginia resident Greg Weisiger asking the commission to reconsider denying the $886 million to SpaceX. "Petitioner is at an absolute loss to understand the Commission's logic with these denials," wrote Weisiger, who lives in Midlothian, Virginia. "It is abundantly clear that Starlink has a robust, reliable, affordable service for rural and insular locations in all states and territories."

The petition arrived a few weeks after the FCC denied SpaceX's appeal to receive $886 million from the commission's Rural Digital Opportunity Fund, which is designed to subsidize 100Mbps to gigabit broadband across the US. SpaceX wanted to use the funds to expand Starlink access in rural areas. But the FCC ruled that "Starlink is not reasonably capable of offering the required high-speed, low latency service throughout the areas where it won auction support." Weisiger disagrees. In his petition, he writes that the FCC's decision will deprive him of federal support to bring high-speed internet to his home. "Thousands of other Virginia locations were similarly denied support," he added.

An anonymous reader quotes a report from Ars Technica: On Thursday, UK's Government Communications Headquarters (GCHQ) announced the release of previously unseen images and documents related to Colossus, one of the first digital computers. The release marks the 80th anniversary of the code-breaking machines that significantly aided the Allied forces during World War II. While some in the public knew of the computers earlier (PDF), the UK did not formally acknowledge the project's existence until the 2000s.

Colossus was not one computer but a series of computers developed by British scientists between 1943 and 1945. These 2-meter-tall electronic beasts played an instrumental role in breaking the Lorenz cipher, a code used for communications between high-ranking German officials in occupied Europe. The computers were said to have allowed allies to "read Hitler's mind," according to The Sydney Morning Herald. The technology behind Colossus was highly innovative for its time. Tommy Flowers, the engineer behind its construction, used over 2,500 vacuum tubes to create logic gates, a precursor to the semiconductor-based electronic circuits found in modern computers. While 1945's ENIAC was long considered the clear front-runner in digital computing, the revelation of Colossus' earlier existence repositioned it in computing history. (However, it's important to note that ENIAC was a general-purpose computer, and Colossus was not.)

GCHQ's public sharing of archival documents includes several photos of the computer at different periods and a letter discussing Tommy Flowers' groundbreaking work that references the interception of "rather alarming German instructions." Following the war, the UK government issued orders for the destruction of most Colossus machines, and Flowers was required to turn over all related documentation. The GCHQ claims that the Colossus tech "was so effective, its functionality was still in use by us until the early 1960s." In the GCHQ press release, Director Anne Keast-Butler paid tribute to Colossus' place in the UK's lineage of technological innovation: "The creativity, ingenuity and dedication shown by Tommy Flowers and his team to keep the country safe were as crucial to GCHQ then as today."

Verizon is writing down the value of its business services division by $5.8 billion, a sign of the company's declining enterprise operations. From a report: The wireless carrier said in a filing Wednesday that the non-cash goodwill impairment charge was due to "secular declines, as well as continuing competitive and macroeconomic pressure." As a result of the impairment, Verizon said the balance of its business unit was $1.7 billion at the end of 2023.

The decline is tied to the telecommunications giant's legacy wireline operations, which provide fixed-line communications services for businesses, through copper or fiber wires. This segment has seen demand drop considerably as its mobile business service has surged. Verizon's wireline business revenue fell 8.1% through the third quarter and is likely to stay muted in 2024, according to Bloomberg Intelligence.

Verizon has agreed to pay $100 million to settle a class-action lawsuit over its monthly "Administrative and Telco Recovery Charge." The telecom giant will distribute the funds to customers who submit claims, with individuals receiving up to $100 each. Though admitting no wrongdoing, Verizon said it "continues to deny that it did anything wrong." The company defended its right to impose the charge, which was recently raised from $1.95 to $3.30 per month per line, and warned it may increase the fee again in the future. Settlement emails are still going out to eligible customers, who have until April 15 to file.

For the third time in under a year, film studios are pressing Reddit to reveal users allegedly discussing piracy, despite two prior failed attempts. Studios including Voltage Holdings and Screen Media have filed fresh motions to compel Reddit to comply with a subpoena seeking IP addresses and logs of six Redditors, claiming the information is needed for copyright suits against internet provider Frontier Communications.

The same federal judge previously denied the studios' bid to unmask Reddit users, citing First Amendment protections. However, the studios now argue IP addresses fall outside privacy rights. Reddit maintains the new subpoena fails to meet the bar for identifying anonymous online speakers.

ScienceAlert reminds us that plants exude "a fine mist of airborne compounds that they use to communicate and protect themselves." And while they've been detected in over 80 plant species, now researchers have applied real-time imaging techniques "to reveal how plants receive and respond to these aerial alarms." Yuri Aratani and Takuya Uemura, molecular biologists at Saitama University in Japan, and colleagues rigged up a pump to transfer compounds emitted by injured and insect-riddled plants onto their undamaged neighbors, and a fluorescence microscope to watch what happened. Caterpillars (Spodoptera litura) were set upon leaves cut from tomato plants and Arabidopsis thaliana, a common weed in the mustard family, and the researchers imaged the responses of a second, intact, insect-free Arabidopsis plant to those danger cues.

These plants weren't any ordinary weeds: they had been genetically altered so their cells contained a biosensor that fluoresced green when an influx of calcium ions was detected... [T]he team visualized how plants responded to being bathed in volatile compounds, which plants release within seconds of wounding. It wasn't a natural set-up; the compounds were concentrated in a plastic bottle and pumped onto the recipient plant at a constant rate, but this allowed the researchers to analyze what compounds were in the pungent mix...

[T]he undamaged plants received the messages of their injured neighbors loud and clear, responding with bursts of calcium signaling that rippled across their outstretched leaves... [G]uard cells generated calcium signals within a minute or so, after which mesophyll cells picked up the message... "We have finally unveiled the intricate story of when, where, and how plants respond to airborne 'warning messages' from their threatened neighbors," says Masatsugu Toyota, a molecular biologist at Saitama University in Japan and senior author of the study.
