Dish Says It Met Its FCC Deadline To Cover 70 Percent of the US Population 13

According to Dish, the company says it now covers 70 percent of the U.S. population and has "also satisfied all other June 14, 2023 FCC commitments." The Verge reports: In meeting this FCC milestone, Dish says it has deployed over 15,000 5G cell sites and would like to remind us that it's still the first wireless provider in the country to launch voice calling over 5G, known as VoNR -- Voice over New Radio. This is all well and good, but Dish's wireless service still doesn't look quite the same as AT&T's or Verizon's. The network itself is very much still in beta testing under its Project Genesis program, which requires you to purchase a new phone specially equipped to use new network features like three-carrier aggregation. The network is available to Boost customers in supported markets, but they need to use a phone that supports band 70 to access Dish's 5G -- and those are still uncommon.

FCC Chair To Investigate Exactly How Much Everyone Hates Data Caps (arstechnica.com) 67

Federal Communications Commission Chairwoman Jessica Rosenworcel wants the FCC to open a formal inquiry into how data caps harm Internet users and why broadband providers still impose the caps. The inquiry could eventually lead to the FCC regulating how Internet service providers such as Comcast impose limits on data usage. From a report: Rosenworcel yesterday announced that she asked fellow commissioners to support a Notice of Inquiry on the topic. Among other things, the Notice would seek comment from the public "to better understand why the use of data caps continues to persist despite increased broadband needs of consumers and providers' demonstrated technical ability to offer unlimited data plans."

The inquiry would also seek comment on "trends in consumer data usage... on the impact of data caps on consumers, consumers' experience with data caps, how consumers are informed about data caps on service offerings, and how data caps impact competition." Finally, Rosenworcel wants to seek comment about the FCC's "legal authority to take actions regarding data caps." "In particular, the agency would like to better understand the current state of data caps, their impact on consumers, and whether the Commission should consider taking action to ensure that data caps do not cause harm to competition or consumers' ability to access broadband Internet services," the press release said.

$930 Million in Grants Announced in Biden's Effort To Expand Internet Access (apnews.com) 58

The massive federal effort to expand internet access to every home in the U.S. took a major step forward on Friday with the announcement of $930 million in grants to shore up connections in remote parts of Alaska, rural Texas and dozens of other places where significant gaps in connectivity persist. From a report: The so-called middle mile grants, announced by the Department of Commerce, are meant to create large-scale networks that will enable retail broadband providers to link subscribers to the internet. Department officials likened the role of the middle mile -- the midsection of the infrastructure necessary to enable internet access, composed of high-capacity fiber lines carrying huge amounts of data at very high speeds -- to how the interstate highway system forged connections between communities. "These networks are the workhorses carrying large amounts of data over very long distances," said Mitch Landrieu, the White House's infrastructure coordinator, in a media Zoom call. "They're the ones that are bridging the gap between the larger networks and the last mile connections, from tribal lands to underserved rural and remote areas to essential institutions like hospitals, schools, libraries and major businesses."

Bipartisan Bill Denies Section 230 Protection for AI (axios.com) 34

Sens. Josh Hawley and Richard Blumenthal want to clarify that the internet's bedrock liability law does not apply to generative AI, per a new bill introduced Wednesday. From a report: Legal experts and lawmakers have questioned whether AI-created works would qualify for legal immunity under Section 230 of the Communications Decency Act, the law that largely shields platforms from lawsuits over third-party content. It's a newly urgent issue thanks to the explosive of generative AI. The new bipartisan bill bolsters the argument that Section 230 doesn't cover AI-generated work. It also gives lawmakers an opening to go after Section 230 after vowing to amend it, without much success, for years.

Section 230 is often credited as the law that allowed the internet to flourish and for social media to take off, as well as websites hosting travel listings and restaurant reviews. To its detractors, it goes too far and is not fit for today's web, allowing social media companies to leave too much harmful content up online. Hawley and Blumenthal's "No Section 230 Immunity for AI Act" would amend Section 230 "by adding a clause that strips immunity from AI companies in civil claims or criminal prosecutions involving the use or provision of generative AI," per a description of the bill from Hawley's office.

Comcast Complains To FCC That Listing All of Its Monthly Fees is Too Hard (arstechnica.com) 109

mschaffer shares a report: Comcast and other ISPs have annoyed customers for many years by advertising low prices and then charging much bigger monthly bills by tacking on a variety of fees. While some of these fees are related to government-issued requirements and others are not, poorly trained customer service reps have been known to falsely tell customers that fees created by Comcast are mandated by the government. The FCC rules will force ISPs to accurately describe fees in labels given to customers, but Comcast said it wants the FCC to rescind a requirement related to "fees that ISPs may, but are not obligated to, pass through to customers." These include state Universal Service fees and other local fees. As Comcast makes clear, it isn't required to pass these costs on to customers in the form of separate fees. Comcast could stop charging the fees and raise its advertised prices by the corresponding amount to more accurately convey its actual prices to customers. Instead, Comcast wants the FCC to change the rule so that it can continue charging the fees without itemizing them..

I suppose it's just easier to grab people's money than it is to make up names for the fees, Mschaffer adds.

UK Communications Regulator Ofcom Says Hackers Stole Confidential Data (bloomberg.com) 5

The hackers responsible for the MOVEit cyberattack downloaded confidential information from UK communications regulator Ofcom about companies it regulates, as well as its own employees -- adding to a string of victims which includes IAG SA's British Airways and the British Broadcasting Corporation. From a report: "A limited amount of information about certain companies we regulate -- some of it confidential -- along with personal data of 412 Ofcom employees, was downloaded during the attack," an Ofcom spokesman said by email. "We took immediate action to prevent further use of the MOVEit service and to implement the recommended security measures. We also swiftly alerted all affected Ofcom-regulated companies, and we continue to offer support and assistance to our colleagues."

'He's About to Graduate College and Join SpaceX as an Engineer. He's 14.' (yahoo.com) 91

"Kairan Quazi will probably need someone to drive him to work at SpaceX," writes the Los Angeles Times — because "He's only 14." The teen is scheduled to graduate this month from the Santa Clara University School of Engineering before starting a job as a software engineer at the satellite communications and spacecraft manufacturer... The soft-spoken teen said working with Starlink — the satellite internet team at SpaceX — will allow him to be part of something bigger than himself. That is no small feat for someone who has accomplished so much at such a young age...

The youngster jumped from third grade to a community college, with a workload that he felt made sense. "I felt like I was learning at the level that I was meant to learn," said Kairan, who later transferred to Santa Clara University... Kairan's family told BrainGain Magazine that when he was 9, IQ tests showed that his intelligence was in the 99.9th percentile of the general population. Asked if he's a genius, he recalled his parents telling him, "Genius is an action â it requires solving big problems that have a human impact." Once accepted to the engineering school at Santa Clara University as a transfer student, Kairan felt that he had found his freedom to pursue a career path that allowed him to solve those big problems.

While in college, Kairan and his mother made a list of places where he could apply for an internship. Only one company responded. Lama Nachman, director of the Intelligent Systems Research Lab at Intel, took a meeting with 10-year-old Kairan, who expected it to be brief and thought she would give him the customary "try again in a few years," he said. She accepted him. "In a sea of so many 'no's' by Silicon Valley's most vaunted companies, that ONE leader saying yes ... one door opening ... changed everything," Kairan wrote on his LinkedIn page...

Asked what he plans to wear on his first day, Kairan joked in an email that he plans "to show up in head to toe SpaceX merch. I'll be a walking commercial! Joking aside, I'll probably wear jeans and a t-shirt so I can be taken seriously as an engineer."

Arctic Could Be Sea Ice-Free in the Summer by the 2030s 67

New research suggests that Arctic summer sea ice could melt almost completely by the 2030s, a decade earlier than previously projected, even with significant greenhouse gas emissions reductions. Smithsonian Magazine reports: "We are very quickly about to lose the Arctic summer sea-ice cover, basically independent of what we are doing," Dirk Notz, a climate scientist at the University of Hamburg in Germany tells the New York Times' Raymond Zhong. "We've been waiting too long now to do something about climate change to still protect the remaining ice." An ice-free summer, also called a "blue ocean event," will happen when the sea ice drops below one million square kilometers (386,102 square miles), writes Jonathan Bamber, a professor of physical geography at the University of Bristol, in the Conversation. This equates to just 15 percent of the Arctic's seasonal minimum ice cover of the late 1970s, per the Times.

Previous assessments using models have estimated an ice-free summer under high and intermediate emissions scenarios by 2050. But researchers noticed differences between what climate models predicted about what would happen to sea ice and what they've actually seen through observations, according to Bob Weber of the Canadian Press. "The models, on average, underestimate sea ice decline compared with observations," says Nathan Gillett, an environment and climate change Canada scientist, to Weber.

Now, in a new study published in Nature Communications, Notz, Gillett and their colleagues tweaked these models to more closely fit satellite data collected over the past 40 years. Using these modified models, the researchers projected ice changes under different possible levels of greenhouse gas emissions. Their paper suggests that regardless of emissions scenario, "we may experience an unprecedented ice-free Arctic climate in the next decade or two." Under a high emissions scenario, the Arctic could see a sustained loss of sea ice from August until as late as October before the 2080s, lead author Seung-Ki Min, a climate scientist at Pohang University of Science and Technology in South Korea, tells CNN's Rachel Ramirez.

Tesla Orders Parts For 375K Cybertrucks In 2024 (electrek.co) 60

schwit1 shares a report from Electrek: Tesla is planning to produce 375,000 Cybertrucks per year and have release candidates by late August, according to communications they sent to suppliers. Tesla's latest official comment on the timeline is a planned delivery event "around the end of Q3," which would mean around the end of September 2023.

Recently, CEO Elon Musk also gave a Tesla Cybertruck production volume estimate at Tesla's annual shareholders meeting. In his comment, he first said about 250,000 units per year, but the CEO also added that he believes it could be between 250,000 and 500,000 units a year. Now, Electrek gets more details through communications that Tesla sent to suppliers for the Cybertruck program, which it calls "Project Everest," internally and with suppliers.

Tesla has asked suppliers to plan to meet a base production volume of 375,000 Cybertrucks per year. For a base volume, it seems to be a bit more aggressive than what Musk communicated publicly at Tesla's annual shareholder's meeting, but Tesla has been frequently adjusting to target. Earlier this year, it was about 100,000 units lower. Also, the number is planned for the production lines running at 85% efficiency.

Artificial Photosynthesis Could Be The Secret to Colonizing Space (sciencealert.com) 23

Artificial photosynthesis, inspired by the natural process that enables plants to convert sunlight, water, and carbon dioxide into oxygen and energy, could be crucial for space exploration and colonization. By using semiconductor materials and metallic catalysts, these devices could efficiently produce oxygen and recycle carbon dioxide, reducing reliance on heavy and unreliable systems currently used on the International Space Station. ScienceAlert reports: As my colleagues and I have investigated in a new paper, published in Nature Communications, recent advances in making artificial photosynthesis may well be key to surviving and thriving away from Earth. [...] We produced a theoretical framework to analyze and predict the performance of such integrated "artificial photosynthesis" devices for applications on Moon and Mars. Instead of chlorophyll, which is responsible for light absorption in plants and algae, these devices use semiconductor materials which can be coated directly with simple metallic catalysts supporting the desired chemical reaction. Our analysis shows that these devices would indeed be viable to complement existing life support technologies, such as the oxygen generator assembly employed on the ISS. This is particularly the case when combined with devices which concentrate solar energy in order to power the reactions (essentially large mirrors which focus the incoming sunlight).

There are other approaches too. For example, we can produce oxygen directly from lunar soil (regolith). But this requires high temperatures to work. Artificial photosynthesis devices, on the other hand, could operate at room temperature at pressures found on Mars and the Moon. That means they could be used directly in habitats and using water as the main resource. This is particularly interesting given the stipulated presence of ice water in the lunar Shackleton crater, which is an anticipated landing site in future lunar missions.

On Mars, the atmosphere composes of nearly 96% carbon dioxide - seemingly ideal for an artificial photosynthesis device. But the light intensity on the red planet is weaker than on Earth due to the larger distance from the Sun. So would this pose a problem? We actually calculated the sunlight intensity available on Mars. We showed that we can indeed use these devices there, although solar mirrors become even more important. [...] The returns would be huge. For example, we could actually create artificial atmospheres in space and produce chemicals we require on long-term missions, such as fertilizers, polymers, or pharmaceuticals. Additionally, the insights we gain from designing and fabricating these devices could help us meet the green energy challenge on Earth.

10 Years After Snowden's First Leak, What Have We Learned? (theregister.com) 139

An anonymous reader quotes a report from The Register: The world got a first glimpse into the US government's far-reaching surveillance of American citizens' communications -- namely, their Verizon telephone calls -- 10 years ago this week when Edward Snowden's initial leaks hit the press. [...] In the decade since then, "reformers have made real progress advancing the bipartisan notion that Americans' liberty and security are not mutually exclusive," [US Senator Ron Wyden (D-OR)] said. "That has delivered tangible results: in 2015 Congress ended bulk collection of Americans' phone records by passing the USA Freedom Act." This bill sought to end the daily snooping into American's phone calls by forcing telcos to collect the records and make the Feds apply for the information.

That same month, a federal appeals court unanimously ruled that the NSA's phone-records surveillance program was unlawful. The American Civil Liberties Union (ACLU) and the New York Civil Liberties Union sued to end the secret phone spying program, which had been approved by the Foreign Intelligence Surveillance Court, just days after Snowden disclosed its existence. "Once it was pushed out into open court, and the court was able to hear from two sides and not just one, the court held that the program was illegal," Ben Wizner, director of the ACLU Speech, Privacy and Technology project, told The Register. The Freedom Act also required the federal government to declassify and release "significant" opinions of the Foreign Intelligence Surveillance Court (FISC), and authorized the appointment of independent amici -- friends of the court intended to provide an outside perspective. The FISC was established in 1978 under the FISA -- the legislative instrument that allows warrantless snooping. And prior to the Freedom Act, this top-secret court only heard the government's perspective on things, like why the FBI and NSA should be allowed to scoop up private communications.

"To its credit, the government has engaged in reforms, and there's more transparency now that, on the one hand, has helped build back some trust that was lost, but also has made it easier to shine a light on surveillance misconduct that has happened since then," Jake Laperruque, deputy director of the Center for Democracy and Technology's Security and Surveillance Project, told The Register. Wyden also pointed to the sunsetting of the "deeply flawed surveillance law," Section 215 of the Patriot Act, as another win for privacy and civil liberties. That law expired in March 2020 after Congress did not reauthorize it. "For years, the government relied on Section 215 of the USA Patriot Act to conduct a dragnet surveillance program that collected billions of phone records (Call Detail Records or CDR) documenting who a person called and for how long they called them -- more than enough information for analysts to infer very personal details about a person, including who they have relationships with, and the private nature of those relationships," Electronic Frontier Foundation's Matthew Guariglia, Cindy Cohn and Andrew Crocker said.
James Clapper, the former US Director of National Intelligence, "stated publicly that the Snowden disclosures accelerated by seven years the adoption of commercial encryption," Wizner said. "At the individual level, and at the corporate level, we are more secure."

"And at the corporate level, what the Snowden revelations taught big tech was that even as the government was knocking on the front door, with legal orders to turn over customer data, it was breaking in the backdoor," Wizner added. "Government was hacking those companies, finding the few points in their global networks where data passed unencrypted, and siphoning it off." "If you ask the government -- if you caught them in a room, and they were talking off the record -- they would say the biggest impact for us from the Snowden disclosures is that it made big tech companies less cooperative," he continued. "I regard that as a feature, not a bug."

The real issue that the Snowden leaks revealed is that America's "ordinary system of checks and balances doesn't work very well for secret national security programs," Wizner said. "Ten years have gone by," since the first Snowden disclosures, "and we don't know what other kinds of rights-violating activities have been taking place in secret, and I don't trust our traditional oversight systems, courts and the Congress, to ferret those out," Wizner said. "When you're dealing with secret programs in a democracy, it almost always requires insiders who are willing to risk their livelihoods and their freedom to bring the information to the public."

Satellite Beams Solar Power Down To Earth, In First-of-a-Kind Demonstration (science.org) 75

Researchers at the California Institute of Technology (Caltech) have successfully demonstrated the capability of steering power in a microwave beam from a satellite to targets in space, as well as transmitting some of that power to a detector on Earth. Science Magazine reports: The Caltech mission, funded by the Donald Bren Foundation and Northrop Grumman Corporation, aimed to go a step further with lightweight, inexpensive, and flexible components. The microwave transmitter was an array of 32 flat antennas packed onto a surface slightly larger than a dinner plate. By varying the timing of signals sent to the different antennas, the researchers could steer the array's beam. They pointed it at a pair of microwave receivers about a forearm's distance away and switched the beam from one receiver to the other at will, lighting up an LED on each.

The transmitted power was small, just 200 milliwatts, less than that of a cellphone camera light. But the team was still able to steer the beam toward Earth and detect it with a receiver at Caltech. "It was a proof of concept," says Caltech electrical engineer Ali Hajimiri. "It indicates what an overall system can do."

The Caltech spacecraft still has two more planned experiments. One is now testing 32 different varieties of solar cell to see which best survives the rigors of space. The second is a folded piece of ultralight composite material that will unfurl into a sail-like structure 2 meters across. Although the sail will not hold any solar cells, it is meant to test the kind of thin, flexible, and large deployments required for a future power station.

Health Firm 'Grail' Wrongly Told Hundreds of People They Might Have Cancer (cbsnews.com) 27

An anonymous reader quotes a report from CBS News: A biotechnology company selling a $949 blood test that it bills as a "first of its kind" to detect cancer said it incorrectly informed about 400 customers that they might have the disease. The Menlo Park, California, company, called Grail, said it sent a form letter to some customers who had bought its Galleri test, which detects a marker for more than 50 types of cancer, "stating incorrectly that a cancer signal was detected," a company spokeswoman told CBS MoneyWatch in a statement. The company blamed a vendor, PWN Health, for the error, citing a "software configuration issue."

In a statement, PWN Health said it said the problem was due to "a misconfiguration of our patient engagement platform used to send templated communications to individuals." It added that it has added processes to make sure such a mistake doesn't occur again, and started contacting the people who received the erroneous letters within 36 hours. The error comes amid an increased demand for health care screening tests, especially for chronic diseases such as cancer.

Grail is billing its service as a complement to routine single-cancer tests for diseases such as colon or breast cancer, and said that the blood test can detect forms of the disease that aren't routinely screened for, such as in the gallbladder and pancreas. Grail said it hasn't received reports of patient harm or "adverse events" due to the erroneous letters.
"After being notified of the incident, Grail immediately began outreach by phone or email to all individuals who received the PWNHealth letter, and we continued our efforts until we confirmed we successfully reached each individual via phone, email or letter," the spokeswoman said. "The issue was in no way related to or caused by an incorrect Galleri laboratory test result."

More than half the erroneous letters were sent to customers who hadn't had their blood drawn yet for the Galleri test, the spokeswoman added.

On Monday, Illumina filed an appeal against a FTC order, "demanding that it divest cancer diagnostic test maker Grail over competition concerns in the U.S. market for cancer tests," reports Reuters. According to the filing, Illumina is arguing that the FTC "violated due process by depriving Illumina and Grail of a fair proceeding before an impartial tribunal."

Can Open Source Speed the Adoption of Clean-Energy Microgrids? (linuxfoundation.org) 38

This week the Linux Foundation announced the publication of The Open Source Opportunity for Microgrids: Five Ways to Drive Innovation and Overcome Market Barriers for Energy Resilience. "The research informs readers about microgrids — groups of distributed energy resources designed to improve energy resiliency, with the ability to operate as part of a larger electrical grid, or separately as an island."

The report highlights the current state of the microgrid market and explores the potential for open source technology to accelerate the adoption of microgrids worldwide... The report concludes that microgrids are an essential tool to improve energy resilience and advance decarbonization, and that the market faces a range of challenges that the open source ecosystem is well positioned to address.
Among other things, the report "examines how participation in relevant open source programs and activities can help address gaps and challenges," according to the announcement, "and accelerate the learning, development, and governance of microgrid initiatives." One focus of the report is "enabling market innovation toward energy resilience at scale, supporting the Energy sector to adopt proven open source-enabled business models, security benefits, and cost reductions demonstrated in the IT and Telecom industries."

And according to the foundation's senior vice president of research and communications, the report also "describes the opportunities for open source to accelerate the proliferation of microgrids as a mechanism for clean energy production and consumption."

Pentagon Awards SpaceX With Ukraine Contract For Starlink Satellite Internet (cnbc.com) 40

The Pentagon has announced that it will purchase Starlink satellite internet terminals from SpaceX to provide communication capabilities to Ukraine as it defends itself against a full-scale Russian invasion. "We continue to work with a range of global partners to ensure Ukraine has the satellite and communication capabilities they need. Satellite communications constitute a vital layer in Ukraine's overall communications network and the department contracts with Starlink for services of this type," the Pentagon said in a statement to CNBC. "For operational security reasons and due to the critical nature of these systems -- we do not have additional information regarding specific capabilities, contracts or partners to provide at this time," the statement added. From the report: The first Starlink terminals in Ukraine arrived four days after Russian troops poured over the nation's border in what became the largest air, land and sea assault in Europe since World War II. Ukraine digital minister Mykhailo Fedorov, who had previously asked Musk for the capability on Twitter, posted that Starlink was "here" in Ukraine -- with a photo showing more than two dozen boxes in the back of a truck. Musk said in October that SpaceX wouldn't be able to continue funding use of Starlink terminals in the country out of its own coffers "indefinitely," after a report from CNN said the company had asked the Pentagon to cover the cost.

Western officials have previously hailed Musk's decision to equip Ukraine with Starlink internet, citing the colossal and indiscriminate Russian shelling on civilian infrastructure that has left large swaths of the country without communications. Musk reportedly told the Pentagon in October he would no longer finance the Starlink terminals in Ukraine as the country prepared to fight through the harsh winter months. However, the billionaire reversed course and did continue to fund the service.

Supreme Court Declines To Hear Bid To Sue Reddit Over Child Porn (reuters.com) 99

An anonymous reader quotes a report from Reuters: The U.S. Supreme Court on Tuesday declined to hear a bid by child pornography victims to overcome a legal shield for internet companies in a case involving a lawsuit accusing Reddit Inc of violating federal law by failing to rid the discussion website of this illegal content. The justices turned away the appeal of a lower court's decision to dismiss the proposed class action lawsuit on the grounds that Reddit was shielded by a U.S. statute called Section 230, which safeguards internet companies from lawsuits for content posted by users but has an exception for claims involving child sex trafficking. The Supreme Court on May 19 sidestepped an opportunity to narrow the scope of Section 230 immunity in a separate case.

Section 230 of the Communications Decency Act of 1996 protects "interactive computer services" by ensuring they cannot be treated as the "publisher or speaker" of information provided by users. The Reddit case explored the scope of a 2018 amendment to Section 230 called the Fight Online Sex Trafficking Act (FOSTA), which allows lawsuits against internet companies if the underlying claim involves child sex trafficking. Reddit allows users to post content that is moderated by other users in forums called subreddits. The case centers on sexually explicit images and videos of children posted to such forums by users. The plaintiffs -- the parents of minors and a former minor who were the subjects of the images -- sued Reddit in 2021 in federal court in California, seeking monetary damages. The plaintiffs accused Reddit of doing too little to remove or prevent child pornography and of financially benefiting from the illegal posts through advertising in violation of a federal child sex trafficking law.

The San Francisco-based 9th U.S. Circuit Court of Appeals in 2022 concluded that in order for the exception under FOSTA to apply, plaintiffs must show that an internet company "knowingly benefited" from the sex trafficking through its own conduct. Instead, the 9th Circuit concluded, the allegations "suggest only that Reddit 'turned a blind eye' to the unlawful content posted on its platform, not that it actively participated in sex trafficking." Reddit said in court papers that it works hard to find and prevent the sharing of child sexual exploitation materials on its platform, giving all users the ability to flag posts and using dedicated teams to remove illegal content.

Adventures on Mars: 'Ingenuity' Helicopter Survives a Communications Blackout (nasa.gov) 22

The Mars helicopter 'Ingenuity' recently completed its 47th, 48th, and 49th flight, NASA reports on the blog for its Mars rover 'Perseverance'. That rover is making a "long ascent" up the delta in Mars' Jezero crater, "an area where scientists surmise that, billions of years ago, a river once flowed into a lake.

On its 47th flight, Ingenuity attempted "tactical and scientific scouting" for the rover, but "just narrowly missing the main area of interest." But then... Ingenuity's 48th flight produced a treasure trove of aerial images showing the exact area of interest at a resolution several orders of magnitude better than anything prior. All of these images were downlinked to Earth and provided to rover planners and scientists a full two weeks before the rover would reach this area... [T]he team chose to send the helicopter farther up the delta rather than perform additional scouting flights in the region... The Guidance Navigation and Control team once again managed to push the flight envelope with a 16-meter vertical popup at the end of the flight. At the peak, Ingenuity snapped the highest suborbital picture taken of the Martian surface since landing...

That downlink was the last time the team would hear from the helicopter for an agonizingly long time. Eager to continue up the delta, the team tried and failed to uplink the instructions for Flight 50 several times. Sol after sol, the helicopter remained elusive. Each time, the downlinked telemetry from the Helicopter Base Station (HBS) on the rover would come back showing no radio sign of the helicopter... When the rover emerged from the communications shadow on its way to Foel Drygarn and the helicopter was still nowhere to be found, the situation began to generate some unease... In more than 700 sols operating the helicopter on Mars, not once had we ever experienced a total radio blackout. Even in the worst communications environments, we had always seen some indication of activity...

Finally, on Sol 761, nearly a week after our first missed check-in, our communications team observed a single, lonely radio ACK (radio acknowledgement) at 9:44 LMST (Local Mean Solar Time), exactly the time when we'd expect to see the helicopter wakeup. Another single ACK at the same time on Sol 762 confirmed that the helicopter was indeed alive, which came as a welcome relief for the team. Ultimately, this first-of-its-kind communications blackout was a result of two factors. First, the topology between the rover and the helicopter was very challenging for the radio used by Ingenuity. In addition to the aforementioned communications shadow, a moderate ridge located just to the southeast of the Flight 49 landing site separated the helicopter from the rover's operational area. The impact of this ridge would only abate once the rover had gotten uncomfortably close to the helicopter. Second, the HBS antenna is located on the right side of the rover, low enough to the deck to see significant occlusion effects from various part of the rover...

Relying on the helicopter's onboard preflight checks to ensure vehicle safety and banking on solid communications from the rover's imminent proximity, the team uplinked the flight plan. As commanded, Ingenuity woke up and executed its 50th flight on the red planet, covering over 300 meters and setting a new altitude record of 18 m.

The rover had closed to a mere 80 meters by the time the helicopter lifted off in the Martian afternoon Sun.

And Flight 51 happened 9 days later...

Seattle Amazon Workers Plan Walkout Over Return to Office, Climate Concerns (cnn.com) 83

CNN reports: Some Amazon corporate workers have announced plans to walk off the job next week over frustrations with the company's return-to-work policies, among other issues, in a sign of heightened tensions inside the e-commerce giant after multiple rounds of layoffs.

The work stoppage is being jointly organized by an internal climate justice worker group and a remote work advocacy group, according to an email from organizers and public social media posts. Workers participating have two main demands: asking the e-commerce giant to put climate impact at the forefront of its decision making, and to provide greater flexibility for how and where employees work.

The lunchtime walkout is scheduled for May 31, beginning at noon. Organizers have said in an internal pledge that they are only going to go through with the walkout if at least 1,000 workers agree to participate, according to an email from organizers.

The event comes a month after Amazon's return-to-office mandate took effect, reports the Seattle Times — with one software engineer saying they wanted to show Amazon's leadership that "employees need a say in the decisions that affect our lives." In response, an Amazon spokesperson said, "We respect our employees' rights to express their opinions." Drew Herdener, senior vice president for communications at Amazon, said there has been a good energy on the company's South Lake Union campus and other urban centers where Amazon has a significant presence. "We've had a great few weeks with more employees in the office," he said. "As it pertains to the specific topics this group of employees is raising, we've explained our thinking in different forums over the past few months and will continue to do so...."

[Since January], Amazon announced another 9,000 job cuts companywide, but has not notified Washington's unemployment office of the local impact. At the same time Amazon was re-evaluating its teams and workforce, the company announced it would require workers to return to the office at least three times a week beginning May 1. That was a change from Amazon's prior policy, put in place in the second half of 2021, that allowed leaders to decide for their teams where they should work. Announcing the mandate in February, CEO Andy Jassy told employees that senior leaders had observed that it's easier to "learn, model, practice and strengthen our culture when we're in the office together most of the time and surrounded by our colleagues." Boosters for downtown Seattle, where Amazon's headquarters campus is located, cheered the mandate and hoped that thousands of returning workers would enliven the neighborhood.

In response to the return-to-office mandate, more than 20,000 workers signed a petition urging Amazon to reconsider.

50 US Senators Issued Satellite Phones (cbsnews.com) 115

Microsoft Warns That China Hackers Attacked US Infrastructure (cnbc.com) 39

Microsoft has issued a warning that Chinese state-sponsored hackers, known as "Volt Typhoon," have compromised "critical" U.S. cyber infrastructure across various industries with a focus on gathering intelligence. CNBC reports: The Chinese hacking group, codenamed "Volt Typhoon," has operated since mid-2021, Microsoft said in an advisory. The organization is apparently working to disrupt "critical communications infrastructure between the United States and Asia," Microsoft said, to stymie efforts during "future crises." The National Security Agency put out a bulletin (PDF) on Wednesday, detailing how the hack works and how cybersecurity teams should respond.

The attack is apparently ongoing. In an advisory, Microsoft urged impacted customers to "close or change credentials for all compromised accounts." U.S. intelligence agencies became aware of the incursion in February, around the same time that a Chinese spy balloon was downed, the New York Times reported. The infiltration was focused on communications infrastructure in Guam and other parts of the U.S., the Times reported, and was particularly alarming to U.S. intelligence because Guam sits at the heart of an American military response in case of a Taiwanese invasion.

Volt Typhoon is able to infiltrate organizations using a unnamed vulnerability in a popular cybersecurity suite called FortiGuard, Microsoft said. Once the hacking group has gained access to a corporate system, it steals user credentials from the security suite and uses them to try to gain access to other corporate systems. The state-sponsored hackers aren't looking to create disruption yet, Microsoft said. Rather, "the threat actor intends to perform espionage and maintain access without being detected for as long as possible." Infrastructure in nearly every critical sector has been impacted, Microsoft said, including the communications, transport, and maritime industries. Government organizations were also targeted.
