Richard Tribou reports via Phys.Org: NASA’s goal to reduce the costs of the powerful Space Launch System rocket for its Artemis program by 50% was called “highly unrealistic” and a threat to its deep space exploration plans, according to a report by NASA’s Office of the Inspector General released (PDF) on Thursday. The audit says the costs to produce one SLS rocket through its proposed fixed-cost contract will still top $2.5 billion, even though NASA thinks it can shrink that through “workforce reductions, manufacturing and contracting efficiencies, and expanding the SLS’s user base.”

“Given the enormous costs of the Artemis campaign, failure to achieve substantial savings will significantly hinder the sustainability of NASA’s deep space human exploration efforts,” the report warns. The audit looked at NASA’s plans to shift from its current setup among multiple suppliers for the hardware to a sole-sourced services contract that would include the production, systems integration and launch of at least five SLS flights beginning with Artemis V currently slated for as early as 2029. NASA’s claim it could get those costs to $1.25 billion per rocket was taken to task by the audit.

“NASA’s aspirational goal to achieve a cost savings of 50% is highly unrealistic. Specifically, our review determined that cost saving initiatives in several SLS production contracts were not significant,” the audit reads. It does find that rocket costs could approach $2 billion through the first 10 SLS rockets under the new contract, a reduction of 20%. […] Through 2025, the audit stated its Artemis missions will have topped $93 billion, which includes billions more than originally announced in 2012 as years of delays and cost increases plagued the leadup to Artemis I. The SLS rocket represents 26% of that cost to the tune of $23.8 billion. The inspector general makes several recommendations to NASA. The most striking of which is that NASA consider using commercial heavy-lift rockets, such as SpaceX’s Starship and Super Heavy or Blue Origin’s New Glenn, as an alternative to the SLS rocket for future Artemis missions.

“Although the SLS is the only launch vehicle currently available that meets Artemis mission needs, in the next 3 to 5 years other human-rated commercial alternatives that are lighter, cheaper, and reusable may become available,” the audit reads. “Therefore, NASA may want to consider whether other commercial options should be a part of its mid- to long-term plans to support its ambitious space exploration goals.”

Saqib Rahim reports via Wired: It’s been one of the wettest years in California since records began. From October 2022 to March 2023, the state was blasted by 31 atmospheric rivers — colossal bands of water vapor that form above the Pacific and become firehoses when they reach the West Coast. What surprised climate scientists wasn’t the number of storms, but their strength and rat-a-tat frequency. The downpours shocked a water system that had just experienced the driest three years in recorded state history, causing floods, mass evacuations, and at least 22 deaths.

Swinging between wet and dry extremes is typical for California, but last winter’s rain, potentially intensified by climate change, was almost unmanageable. Add to that the arrival of El Nino, and more extreme weather looks likely for the state. This is going to make life very difficult for the dam operators tasked with capturing and controlling much of the state’s water. Like most of the world’s 58,700 large dams, those in California were built for yesterday’s more stable climate patterns. But as climate change taxes the world’s water systems — affecting rainfall, snowmelt, and evaporation — it’s getting tough to predict how much water gets to a dam, and when. Dams are increasingly either water-starved, unable to maintain supplies of power and water for their communities, or overwhelmed and forced to release more water than desired — risking flooding downstream.

But at one major dam in Northern California, operators have been demonstrating how to not just weather these erratic and intense storms, but capitalize on them. Management crews at New Bullards Bar, built in 1970, entered last winter armed with new forecasting tools that gave unprecedented insight into the size and strength of the coming storms — allowing them to strategize how to handle the rain. First, they let the rains refill their reservoir, a typical move after a long drought. Then, as more storms formed at sea, they made the tough choice to release some of this precious hoard through their hydropower turbines, confident that more rain was coming. “I felt a little nervous at first,” says John James, director of resource planning at Yuba Water Agency in northern California. Fresh showers soon validated the move. New Bullards Bar ended winter with plumped water supplies, a 150 percent boost in power generation, and a clean safety record. The strategy offers a glimpse of how better forecasting can allow hydropower to adapt to the climate age.

An anonymous reader quotes a report from Reuters: U.S. President Joe Biden traveled to Philadelphia on Friday to announce the recipients of $7 billion in federal grants across 16 states for the development of seven regional hydrogen hubs, advancing a key part of a plan to decarbonize the U.S. economy. The announcement of the funding to boost manufacturing and blue-collar jobs was held in Pennsylvania — a state that could decide the 2024 presidential election — underscoring the power Biden wields as he spends the upcoming months doling out money flowing from his landmark pieces of legislation that remain largely unknown to large swaths of the American public.

The seven proposed hubs involving companies ranging from Exxon Mobil to Amazon were selected, with their projects spanning 16 states from Pennsylvania to California. The program is intended to jump-start the production of “clean hydrogen” along with the infrastructure needed to get it to industrial users like steelmakers and cement plants. “I’m here to announce one of the largest advanced manufacturing investments in the history of this nation,” Biden said,” He noted that the total investment will reach $50 billion when taking into account additional investments from private companies.

The hub selections will now kick off a long process that includes multiple phases, from design and development to permitting, financing and construction. “It’s not guaranteed that someone selected is even going to make it through negotiations and get awarded the money,” said Jason Munster, who was involved in analyzing the projects for the Department of Energy and is now a hydrogen consultant at CleanEpic. The hubs selected will serve the Middle Atlantic, Appalachian, Midwest, Minnesota and Plains states, the Gulf Coast, Pacific Northwest and California. The two largest projects include $1.2 billion each for Texas and California — the former an oil giant and the other a green energy leader.

Matthew Sparkes reports via NewScientist: A prominent cryptography expert has told New Scientist that a US spy agency could be weakening a new generation of algorithms designed to protect against hackers equipped with quantum computers. Daniel Bernstein at the University of Illinois Chicago says that the US National Institute of Standards and Technology (NIST) is deliberately obscuring the level of involvement the US National Security Agency (NSA) has in developing new encryption standards for “post-quantum cryptography” (PQC). He also believes that NIST has made errors — either accidental or deliberate — in calculations describing the security of the new standards. NIST denies the claims.

Bernstein alleges that NIST’s calculations for one of the upcoming PQC standards, Kyber512, are “glaringly wrong,” making it appear more secure than it really is. He says that NIST multiplied two numbers together when it would have been more correct to add them, resulting in an artificially high assessment of Kyber512’s robustness to attack. “We disagree with his analysis,” says Dustin Moody at NIST. “It’s a question for which there isn’t scientific certainty and intelligent people can have different views. We respect Dan’s opinion, but don’t agree with what he says.” Moody says that Kyber512 meets NIST’s “level one” security criteria, which makes it at least as hard to break as a commonly used existing algorithm, AES-128. That said, NIST recommends that, in practice, people should use a stronger version, Kyber768, which Moody says was a suggestion from the algorithm’s developers.

NIST is currently in a period of public consultation and hopes to reveal the final standards for PQC algorithms next year so that organizations can begin to adopt them. The Kyber algorithm seems likely to make the cut as it has already progressed through several layers of selection. Given its secretive nature, it is difficult to say for sure whether or not the NSA has influenced the PQC standards, but there have long been suggestions and rumors that the agency deliberately weakens encryption algorithms. In 2013, The New York Times reported that the agency had a budget of $250 million for the task, and intelligence agency documents leaked by Edward Snowden in the same year contained references to the NSA deliberately placing a backdoor in a cryptography algorithm, although that algorithm was later dropped from official standards.

According to the New York Times, Chinese-owned bitcoin mining operations in the United States are causing security concerns due to their proximity to important sites and the potential for cyber threats. The Crypto Times reports: There are some mining facilities close to critical sites such as Microsoft data center for Pentagon’s Air Force nuclear’s missile base in Wyoming USA. Officials in U.S. fear Chinese espionage activities at these places. These mining operations began after China banned bitcoin mining in 2021. These individuals sometimes maintain connections with the Chinese Communist Party or state-owned companies which may be kept concealed through multiple layers of companies.

Texas has turned out to be a haven for Chinese-linked Bitcoin mining, with some US states having restrictions but Texas offers incentives. This might pose a threat to the power grid or essential infrastructure. A new concern has recently been raised in a report related to a potential cyber strike on the US infrastructure by China in case a major conflict arose.

An anonymous reader quotes a report from Electrek: Tesla has officially released its API documentation to support third-party apps — after years of operating in a gray zone with an unofficial API. For now, it is geared toward fleet management, but developers are hoping it is a first step toward creating a healthy app ecosystem. […] So far, it still only covers the command that you can send to your car through the Tesla app, and it can ping the data from your car that goes to the app. In short, it is going to make official all the third-party fleet management apps, smartwatch integration apps, etc.

In the documentation, Tesla writes that all third-party apps are going to have to go through the new API starting next year: “Following the release of Tesla Vehicle Command SDK support for REST API vehicle command endpoints is now reaching end of life. Starting 2024 most vehicles will require sending commands via Tesla Vehicle Command SDK.” Tesla put together a process to onboard those apps on its website. If you are using some of those apps, you will likely receive a notification to give them official authorization to access car data.

Keumars Afifi-sabet reports via TechRadar: Lenovo has the green light to see a portfolio of new enterprise-focused devices powered by Esper Foundation — a custom Android operating system — and bundled with a complementary mobile device management (MDM) platform. The firm’s first device running Esper Foundation is the Lenovo ThinkCentre M70a, an all-in-one desktop PC fitted with an up to 12th-Gen Intel Core i9 CPU, alongside 16GB DDR4 RAM and up to 512GB SSD. It’ll be followed by the Lenovo ThinkCentre M70q, M90n-1 IoT, and the ThinkEdge SE30 v2 machines by the end of 2023. Esper Foundation is based on Android 11 and has customizable branding, peripheral compatibility, quarterly security patches, and three years of support. The MDM system, meanwhile, remotely deploys, manages, and updates devices from a single view.

By integrating a custom version of Android in its PCs, Lenovo is banking on the Esper Foundation OS appealing to businesses as an alternative to Windows, as well as Google’s own ChromeOS. With platforms like Esper’s, there may well be a means to find a rival to compete with Windows in the enterprise, particularly in highly niche industries such as the retail, hospitality, and healthcare industries — at which Esper Foundation is directed. “This collaboration is another step forward in Lenovo’s drive to meet changing customer demand across retail, hospitality, healthcare, and other industries,” said Johanny Payero, Lenovo’s director of global advanced solutions marketing and strategy. “Dedicated devices are proliferating across several key industries, and our new joint solution with Esper allows us to deliver the best of Android with the consistency and predictability of Lenovo’s x86 devices.”

An anonymous reader quotes a report from TechCrunch: It hasn’t been a great time in recent quarters for PC companies, but with IDC, Gartner and Canalys all reporting data for Q3 2023, it shows an improving landscape. While shipments still declined between 7% and 9%, depending on whose data you look at, the decline was slowing. But perhaps the biggest surprise in these numbers was the fact Apple was the biggest loser this quarter, with numbers declining between 23% and 29%.

First, let’s look at the overall numbers. IDC found the market dropped 7.6% year over year with 68.2 million PCs shipped, Gartner reported a 9% decline with 64.3 million units shipped and Canalys found the market down 7% with 65.6 million units shipped. In spite of that, the consensus was that the long PC market decline may be over, and we could be headed for better days with the holiday shopping season approaching in the final quarter. “There is evidence that the PC market’s decline has finally bottomed out,” Mikako Kitagawa, director analyst at Gartner, said in a statement.

When you look at individual manufacturers, Apple experienced by far the biggest decline, with IDC reporting -23.1%, Gartner reporting -24.2% and Canalys -29.1%. The only other company with double-digit reductions was Asus, with -10.7%, -11.5% and -10.7%, respectively. If you’re looking for the only company in positive territory, that would be HP, with IDC and Gartner reporting an increase of 6.4% and Canalys only slightly different at 6.5%.

Google is still wondering if it should make major changes to its homepage. The last experiment we saw filled the usually stark white page with info cards showing things like the weather and stocks, but this new experiment has a much bigger focus on news. From a report: Instead of a homepage featuring only the Google logo, a search box, and a few buttons, this latest experiment looks a lot more like the “Google Discover” newsfeed you get on the Google mobile app. That means rows of news articles that Google has algorithmically detected will interest you, often with wild month-to-month quality swings in the sites it promotes. To the right of the newsfeed is a stack of “at a glance” cards featuring sports scores, stocks, and the weather. The change makes Google look a lot busier — and a lot more like Bing and Yahoo.
