SpaceX Celebrates Third Launch of Starship Rocket Despite Loss of Contact (wftv.com) 70

sixoh1 writes: On the third attempt, SpaceX's Super Heavy booster lofted the Starship vehicle to space on a sub-orbital parabolic trajectory. The test was successful for nearly all of the objectives, including payload delivery functions on Starship that will be used for Starlink deployment and in-space fuel transfers. Unfortunately the booster did not soft-land, and the Starship vehicle was destroyed during re-entry, likely due to unspecified issues with re-starting the Raptor engine and then maintaining attitude control during re-entry. You can watch Starship's third flight test here.

Amazon Tells Warehouse Workers To Close Their Eyes and Think Happy Thoughts (404media.co) 122

Amazon is telling workers to close their eyes and dream of being somewhere else while they're standing in a warehouse. From a report: A worker in one of Amazon's fulfillment centers, who we've granted anonymity, sent 404 Media a photo they took of a screen imploring them to try "savoring" the idea of something that makes them happy -- as in, not being at work, surrounded by robots and packages. "Savoring," the screen says, in a black font over a green block of color. "Close your eyes and think about something that makes you happy." Under that text -- which I can't emphasize enough: it looks like something a 6th grader would make in Powerpoint -- there's a bunch of white space, and a stock illustration of a faceless person in an Amazon vest. He's being urged on by an anthropomorphic stack of Amazon packages with wheels and arms. There's also a countdown timer that says "repeat until timer ends." In the image we saw, it said 10 seconds.

FAA Grants License For SpaceX's Third Starship Launch (space.com) 62

The FAA today awarded a launch license to SpaceX for Starship's third-ever test flight on March 14. "The FAA determined SpaceX met all safety, environmental, policy and financial responsibility requirements," the agency wrote in a post on X this afternoon. Space.com reports: The megarocket has two test flights under its belt so far, which took place in April and November of last year. Starship's two stages failed to separate as planned on the April flight, however, which ended after just four minutes. Things went better in November -- stage separation occurred as planned, for example -- but both stages ended up exploding high in the sky on that mission as well. The FAA wrapped up its investigation into what happened on the November flight late last month. But the agency took some additional time before awarding a license for launch number three today.

Thursday's flight will be different, and bolder, than its predecessors. "The third flight test aims to build on what we've learned from previous flights while attempting a number of ambitious objectives, including the successful ascent burn of both stages, opening and closing Starship's payload door, a propellant transfer demonstration during the upper stage's coast phase, the first ever re-light of a Raptor engine while in space, and a controlled reentry of Starship," SpaceX wrote in a mission description. In addition, Thursday's test launch will aim to bring Starship's upper stage down in the Indian Ocean. The target splashdown zone for the first two test missions, by contrast, was the Pacific Ocean near Hawaii.

America's Last Top Models (newyorker.com) 17

For decades, U.S. inventors sent in models with their patent applications -- gizmos that reveal a secret history of unmet needs and relentless innovation. The New Yorker: The ruins of American invention have been recently resurrected in a former textile mill in Wilmington, Delaware. The Henry Clay Mill, now better known as Hagley Museum and Library Visitor Center, is perched on the banks of Brandywine Creek, at the southern edge of a sprawling estate once owned by the du Pont family; just upstream lies the oldest of the dynasty's several stately homes in the region, as well as the remains of the gunpowder works upon which its fortune was built. One morning, Chris Cascio, a curator, welcomed me into the mill, where the space once occupied by cotton-picking and carding machines now houses a curious exhibit: the scavenged remainders of a much larger, long-lost museum.

From 1790 to 1880, Cascio explained, the U.S. Patent Office first encouraged and then required an inventor to submit a model along with each application. These models -- thousands of miniature devices, often exquisitely detailed -- were then exhibited in Washington, D.C., in the office's model gallery. Sometimes called the "Temple of Invention," the gallery was a bustling landmark: it regularly attracted up to ten thousand visitors a month and was ranked as "the greatest permanent attraction in the city," according to one newspaper. But by the late nineteenth century it had effectively shut its doors. Hagley's latest exhibit, "Nation of Inventors," is the largest permanent public display of patent models since that time.

[...] The U.S. system was also unique in that no other country required a model to accompany a patent application. The reasons why soon became clear. As early as the eighteen-thirties, the collection had outgrown the Patent Office's cramped headquarters at the former Blodgett's Hotel. In 1836, a fire destroyed at least seven thousand models, but, rather than abandon the requirement, the Patent Office doubled down, securing congressional funding to reconstruct the models and laying the foundations for a truly monumental building, with a facade modelled after the Parthenon. The structure, which now houses the Smithsonian's American Art Museum and the National Portrait Gallery, occupies an entire city block. In the engineer Pierre L'Enfant's master plan for the capital, it was intended to serve as a kind of nondenominational "church of the republic," between the White House on one side and the Capitol on the other.

SpaceX Gets E-Band Radio Waves To Boost Starlink Broadband (spacenews.com) 26

Jason Rainbow reports via SpaceNews: SpaceX has secured conditional approval to use extremely high-frequency E-band radio waves to improve the capacity of its low Earth orbit Starlink broadband constellation. The Federal Communications Commission said March 8 it is allowing SpaceX to use E-band frequencies between second-generation Starlink satellites and gateways on the ground, alongside already approved spectrum in the Ka and Ku bands. Specifically, SpaceX is now also permitted to communicate between 71 and 76 gigahertz from space to Earth, and 81-86 GHz Earth-to-space, using the up to 7,500 Gen2 satellites SpaceX is allowed to deploy.

SpaceX has plans for 30,000 Gen2 satellites, on top of the 4,400 Gen1 satellites already authorized by the FCC. However, the FCC deferred action in December 2022 on whether to allow SpaceX to deploy the other three-quarters of its Gen2 constellation, which includes spacecraft closer to Earth to improve broadband speeds. The regulator also deferred action at the time on SpaceX's plans to use E-band frequencies, citing a need to first establish ground rules for using them in space. In a March 8 regulatory filing, the FCC said it found "SpaceX's proposed operations in the E-band present no new or increased frequency conflicts with other satellite operations." But the order comes with multiple conditions, including potentially forcing SpaceX to modify operations if another satellite operator also seeks to use the radio waves.

'Larger Than Everest' Comet Could Become Visible To Naked Eye This Month 54

12P/Pons-Brooks, a Halley-type comet larger than Mount Everest and with a 71.3-year orbit, is expected to become visible to the naked eye in the coming weeks as it makes its closest approach to the sun on April 21. The Guardian reports: While some reports suggest 12P/Pons-Brooks was spotted as far back as the 14th century, it is named after the French astronomer Jean-Louis Pons who discovered it in 1812 and the British-American astronomer William Robert Brooks who observed it on its next orbit in 1883. Thought to have a nucleus about 30km (20 miles) in diameter, it is classed as a cryovolcanic comet, meaning it erupts with dust, gases and ice when pressure builds inside as it is heated. One such outburst last year caused it to brighten a hundredfold and garnered it the sobriquet of "the Devil Comet" after the haze that surrounds it formed a horned shape.

While the comet -- and its green tinge -- has already been spotted in the night sky, experts say it is expected to become even brighter in the coming weeks. "The comet is expected to reach a magnitude of 4.5 which means it ought to be visible from a dark location in the UK," said Dr Paul Strom, an astrophysicist at the University of Warwick. "The comet moves from the constellation of Andromeda to Pisces. As it does so it passes by bright stars which will make it easier to spot on certain dates. In particular, on March 31 12P/Pons-Brooks will be only 0.5 a degree from the bright star called Hamal," he said. But Dr Robert Massey, the deputy executive director of the Royal Astronomical Society, said even if the comet did become brighter it could still be difficult to see, adding that basic instruments such as small telescopes would greatly help.

"If you have a half-decent pair of binoculars, certainly attempt to look for it with those," said Massey, adding that apps that map the sky were also useful. The best views of the comet are currently to be found in the northern hemisphere. Massey said those who wanted to catch a glimpse should venture out on a clear evening and look low in the west-north-west as twilight came to an end. "You want to avoid haze, you want to avoid moonlight, you want to avoid light pollution."

World's Largest Aircraft Goes Supersonic In First Powered Flight (geekwire.com) 32

An anonymous reader quotes a report from GeekWire: Chalk up another milestone for Stratolaunch, the air-launch venture created by the late Microsoft co-founder Paul Allen: The company's mammoth airplane deployed a winged test vehicle for its first rocket-powered flight. Stratolaunch's single-use TA-1 test vehicle blazed a trail for future reusable hypersonic test vehicles that are expected to help the U.S. military catch up on one of the frontiers of aerial combat. TA-1 went supersonic, according to Zachary Krevor, Stratolaunch's president and CEO -- but based on his comments, it may not have quite hit the hypersonic standard of five times the speed of sound. "While I can't share the specific altitude and speed TA-1 reached due to proprietary agreements with our customers, we are pleased to share that in addition to meeting all primary and customer objectives of the flight, we reached high supersonic speeds approaching Mach 5 and collected a great amount of data at an incredible value to our customers," Krevor said in a news release.

Today's test flight took place in the skies above California's Mojave Air and Space Port, where Stratolaunch keeps its twin-fuselage Roc airplane. Roc is the world's biggest operational aircraft, with a wingspan of 385 feet. It's designed to serve as a flying launch pad for rocket-powered vehicles like the TA-1 and its successors. The air-launch concept makes it possible for launch missions to be flown from any airport with a runway that's big enough to accommodate Roc. It's similar to the concept that was used back in 2004 to win the $10 million Ansari X Prize for private spaceflight with financial backing from Paul Allen. [...] This flight was the 14th test mission for Roc, coming after an unpowered separation test of its TA-0 vehicle and two captive-carry test flights for TA-1. Today's test also marked the first in-flight use of Ursa Major's Hadley rocket engine. The primary test objectives included a safe release of TA-1, engine ignition, acceleration, sustained climb in altitude and a controlled splashdown into the Pacific.

Conflicting Values For Hubble Constant Not Due To Measurement Error, Study Finds (arstechnica.com) 64

Jennifer Ouellette reports via Ars Technica: Astronomers have made new measurements of the Hubble Constant, a measure of how quickly the Universe is expanding, by combining data from the Hubble Space Telescope and the James Webb Space Telescope. Their results confirmed the accuracy of Hubble's earlier measurement of the constant's value, according to their recent paper published in The Astrophysical Journal Letters, with implications for a long-standing discrepancy in values obtained by different observational methods known as the "Hubble tension."

There was a time when scientists believed the Universe was static, but that changed with Albert Einstein's general theory of relativity. Alexander Friedmann published a set of equations showing that the Universe might actually be expanding in 1922, with Georges Lemaitre later making an independent derivation to arrive at that same conclusion. Edwin Hubble confirmed this expansion with observational data in 1929. Prior to this, Einstein had been trying to modify general relativity by adding a cosmological constant in order to get a static universe from his theory; after Hubble's discovery, legend has it, he referred to that effort as his biggest blunder.
The article notes how scientists have employed different methods to calculate the Hubble Constant, including observing nearby celestial objects, analyzing gravitational waves from cosmic events, and examining the Cosmic Microwave Background (CMB). However, these approaches yield differing values, highlighting the challenge in pinning down the constant precisely. A recent effort involved making additional observations of Cepheid variable stars, correlating them with the Hubble data. The results further confirmed the accuracy of the Hubble data.

"We've now spanned the whole range of what Hubble observed, and we can rule out a measurement error as the cause of the Hubble Tension with very high confidence," said co-author and team leader Adam Riess, a physicist at Johns Hopkins University. "Combining Webb and Hubble gives us the best of both worlds. We find that the Hubble measurements remain reliable as we climb farther along the cosmic distance ladder. With measurement errors negated, what remains is the real and exciting possibility that we have misunderstood the Universe."

US Intelligence Officer Explains Roswell, UFO Sightings (cnn.com) 43

CNN's national security analyst interviewed a U.S. intelligence officer who worked on the newly-released Defense report debunking UFO sightings — physicist Sean Kirkpatrick. He tells CNN "about two to five percent" of UFO reports are "truly anomalous."

But CNN adds that "he thinks explanations for that small percentage will most likely be found right here on Earth..." This is how Kirkpatrick and his team explain the Roswell incident, which plays a prominent role in UFO lore. That's because, in 1947, a U.S. military news release stated that a flying saucer had crashed near Roswell Army Air Field in New Mexico. A day later, the Army retracted the story and said the crashed object was a weather balloon. Newspapers ran the initial saucer headline, followed up with the official debunking, and interest in the case largely died down. Until 1980, that is, when a pair of UFO researchers published a book alleging that alien bodies had been recovered from the Roswell wreckage and that the U.S. government had covered up the evidence.

Kirkpatrick says his office dug deep into the Roswell incident and found that in the late 1940s and early 1950s, there were a lot of things happening near the Roswell Airfield. There was a spy program called Project Mogul, which launched long strings of oddly shaped metallic balloons. They were designed to monitor Soviet nuclear tests and were highly secret. At the same time, the U.S. military was conducting tests with other high-altitude balloons that carried human test dummies rigged with sensors and zipped into body-sized bags for protection against the elements. And there was at least one military plane crash nearby with 11 fatalities.

Echoing earlier government investigations, Kirkpatrick and his team concluded that the crashed Mogul balloons, the recovery operations to retrieve downed test dummies and glimpses of the charred aftermath of that real plane crash likely combined into a single false narrative about a crashed alien spacecraft...

Since 2020, the Pentagon has standardized, de-stigmatized and increased the volume of reporting on UFOs by the U.S. military. Kirkpatrick says that's the reason the closely covered and widely-mocked Chinese spy balloon was spotted in the first place last year. The incident shows that the U.S. government's policy of taking UFOs seriously is actually working.

The pattern keeps repeating. "Kirkpatrick says, his investigation found that most UFO sightings are of advanced technology that the U.S. government needs to keep secret, of aircraft that rival nations are using to spy on the U.S. or of benign civilian drones and balloons." ("What's more likely?" asked Kirkpatrick. "The fact that there is a state-of-the-art technology that's being commercialized down in Florida that you didn't know about, or we have extraterrestrials?")

But the greatest irony may be that "stories about these secret programs spread inside the Pentagon, got embellished and received the occasional boost from service members who'd heard rumors about or caught glimpses of seemingly sci-fi technology or aircraft. And Kirkpatrick says his investigators ultimately traced this game of top-secret telephone back to fewer than a dozen people... [F]or decades, UFO true believers have been telling us there's a U.S. government conspiracy to hide evidence of aliens. But — if you believe Kirkpatrick — the more mundane truth is that these stories are being pumped up by a group of UFO true believers in and around government."

One Year Later, 81% of SVB's Clients Still Bank With Them - and Big Banks Got Bigger (axios.com) 22

One year after Silicon Valley Bank's collapse and seizure, "Regional bank stocks remain volatile compared to other types of financial institutions," reports the Observer, "indicating investors' lingering worries about the sector."

But not everyone suffered: Benefiting from the crisis were big players, like JPMorgan Chase. After acquiring First Republic's $212.6 billion in loans and $92.4 billion in deposits for just over $10 billion in May 2023, JPMorgan saw a 67 percent year-over-year growth in profits that quarter. Overall, larger commercial banks saw inflows as customers sought safer institutions to hold their money.
And what happened to Silicon Valley Bank? Axios reports: Today, SVB says it's still the same bank customers loved, but with better risk management and some other tweaks, like smaller deposit requirements for startup borrowers, president Marc Cadieux told Axios last month. 81% of SVB's clients from a year ago are still banking with SVB, according to Cadieux, with "thousands of them" returning after initially switching out...

"I think there was an inference that this was a regional bank crisis, but it really wasn't — those were niche banks," Citizens CEO Bruce Van Saun tells Axios. "The failure was is in governance and the business model."

Citizens is America's 14th largest bank, and as its CEO, Van Saun was asked by CNN what caused 2023's failures at other banks: CEO Van Saun: Both of those banks [Signature Bank and Silicon Valley Bank] went from $50 billion in assets to over $200 billion in four years. They grew too fast, took in a high percentage of uninsured deposits, had very concentrated, narrow customer bases so they were susceptible to [deposit] flight risk. They also borrowed short and invested long, which is a cardinal sin of banking. They didn't manage their interest rate risk well because they didn't have the muscle that you would have if you grew slowly over the years and were heavily regulated like bigger banks like ourselves.

CNN: Who deserves more blame: failed banks' management teams for not ensuring proper guardrails were in place or financial supervisors whose jobs are to identify red flags?

Van Saun: It's a joint failure...

CNN: [W]hat about commercial real estate? The number of people working in offices is much, much lower than it was pre-pandemic. Are you bracing for another chapter of banking stress? What is Citizens doing to cushion against potential high losses in the sector given close to one-fifth of your loans are there?

Van Saun: You have to look under the covers. The nature of our portfolio matters.

Within commercial real estate, industrial, warehouse and distribution space is fine. Multi-family homes are generally fine. When it comes to offices, we have certain pockets of life science businesses like lab research facilities that are super safe because they never had to close during Covid. [Loans to general office buildings are riskier though, he said.] We go through all of that and we say we'll lose some money here, but we're not going to lose our shirt and we've put up big reserves against them. We're working on a loan-by-loan basis with our most senior people. I think it's a well-managed process.

New US Defense Department Report Found 'No Evidence' of Alien Technology (theguardian.com) 66

An anonymous reader shared this report from the Guardian: The U.S. is not secretly hiding alien technology or extraterrestrial beings from the public, according to a defense department report.

On Friday, the Pentagon 'published the findings of an investigation conducted by the All-Domain Anomaly Resolution Office (AARO), a government office established in 2022 to detect and, as necessary, mitigate threats including "anomalous, unidentified space, airborne, submerged and transmedium objects"....

AARO investigators, which were "granted full access to all pertinent sensitive [U.S. government] programs", reviewed all official government investigatory efforts since 1945. Investigators also researched classified and unclassified archives, conducted approximately 30 interviews, and collaborated with intelligence community and defense department officials responsible for controlled and special access program oversight, the report revealed.

NPR writes that "Many of the sightings turned out to be drones, weather balloons, spy planes, satellites, rockets and planets, according to the report..." "AARO has found no evidence that any U.S. government investigation, academic-sponsored research, or official review panel has confirmed that any sighting of a UAP represented extraterrestrial technology," Pentagon Press Secretary Maj. Gen. Pat Ryder said in a statement Friday. All investigative efforts concluded that most sightings were ordinary objects and the result of misidentification, Ryder said... The office plans to publish a second volume of the report later this year that covers findings from interviews and research done between November 2023 and April 2024."
The report finds no evidence of any confirmed alien technology, the Guardian notes: It added that sensors and visual observations are imperfect, the vast majority of cases lack actionable data and such available data is limited or of poor quality. The report also said resources and staffing for such programs have largely been irregular and sporadic and that the vast majority of reports "almost certainly" are the result of misidentification. In addition, the report found "no empirical evidence for claims that the [U.S. government] and private companies have been reverse-engineering extraterrestrial technology"...

The report's public release comes as AARO's acting director, Timothy Phillips, told reporters on Wednesday that the US military is developing a UFO sensor and detection system called Gremlin. "If we have a national security site and there are objects being reported that [are] within restricted airspace or within a maritime range or within the proximity of one of our spaceships, we need to understand what that is ... and so that's why we're developing sensor capability that we can deploy in reaction to reports," Phillips said, CNN reports.

Was Avi Loeb Led to His 'Alien Debris' Meteor by the Sound of a Truck? (jhu.edu) 53

Remember Avi Loeb, the Harvard professor who claims fragments of alien technology turned up in a high-speed meteor he retrieved from the waters off of Papua, New Guinea?

"Reanalysis of seismic data now suggests Loeb may have been looking for the meteor remnants in the wrong place," writes the Washington Post: The analysis, led by seismologist Benjamin Fernando of Johns Hopkins University, contends that sound waves purportedly from the meteor exploding in the atmosphere, and cited by Loeb as helping to locate the meteor's debris field, were most likely from a truck driving on a road near the seismometer.
"Interstellar signal linked to aliens was actually just a truck," reads the headline on an announcement from Johns Hopkins University. "The fireball location was actually very far away from where the oceanographic expedition went to retrieve these meteor fragments," Fernando says in the announcement. "Not only did they use the wrong signal, they were looking in the wrong place." Using data from stations in Australia and Palau designed to detect sound waves from nuclear testing, Fernando's team identified a more likely location for the meteor, more than 100 miles from the area initially investigated. They concluded the materials recovered from the ocean bottom were tiny, ordinary meteorites — or particles produced from other meteorites hitting Earth's surface mixed with terrestrial contamination.
"There are hundreds of signals that look just like this on that seismometer in Papua New Guinea in the days before and the days after," Fernando told the Washington Post.

But the newspaper adds that "Loeb, however, stands his ground." "The seismic data is completely irrelevant to the location of the meteor," Loeb told The Washington Post. He said his team based its search coordinates primarily on satellite data from the United States military. A three-year analysis by the United States Space Command supported the hypothesis that the meteor's extreme velocity indicated an origin outside our solar system, Loeb said...

[Fernando] said his team believes the purported velocity of the meteor is the result of a measurement error by a sensor. "We think the most likely case is it's a natural meteor from within our solar system," he said.

In any case, Loeb is not done with the search. When he gets sufficient funding, he told The Post, he's going back to the Pacific in search of larger pieces of whatever splashed into the sea.

Palantir Wins US Army Contract For Battlefield AI 32

Lindsay Clark reports via The Register: Palantir has won a US Army contract worth $178.4 million to house a battlefield intelligence system inside a big truck. In what purports to be the Army's first AI-defined vehicle, Palantir will provide systems for the TITAN "ground station," which is designed to access space, high altitude, aerial, and terrestrial sensors to "provide actionable targeting information for enhanced mission command and long range precision fires", according to a Palantir statement.

TITAN stands for Tactical Intelligence Targeting Access Node, which might sound harmless enough. Who was ever killed by a node? The TITAN solution is built to "maximize usability for soldiers, incorporating tangible feedback and insights from soldier touchpoints at every step of the development and configuration process," the statement said. The aim of the TITAN project is to bring together military software and hardware providers in a new way. These include "traditional and non-traditional partners" of the US armed forces, such as Northrop Grumman, Anduril Industries, L3Harris Technologies, Pacific Defense, SNC, Strategic Technology Consulting, and World Wide Technology, as well as Palantir.

Speaking to Bloomberg, Alex Karp, Palantir's motor-mouth CEO, said TITAN was the logical extension of Maven, a controversial project for using machine learning and engineering to tell people and objects apart in drone footage in which Palantir is a partner and from which Google famously pulled out after employees protested. Karp said TITAN was a partnership between "people who've built software products that have been used on the battlefield and used commercially." "That simple insight which you see in the battlefield in Ukraine, which you see in Israel is something that is hard for institutions to internalize. [For] the Pentagon this step is one of the most historic steps ever because what it basically says is, 'We're going to fight for real, we're going to put the best on the battlefield and the best is not just one company.' It's a team of people led by the most prominent software provider in defense in the world: Palantir," he said.
On Thursday, Palantir was one of the companies included in a new U.S. consortium assembled to support the safe development and deployment of generative AI.

5,800 Pounds of Batteries Tossed Off the ISS in 2021 Fell to Earth Today (space.com) 36

Space.com describes it as "a nearly 3-ton leftover tossed overboard from the International Space Station" — which crashed back to earth today. One satellite tracker claims to have filmed it passing over the Netherlands...

"A couple minutes later reentry and it would have reached Fort Meyers" in Florida, posted astronomer Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics. But instead it re-entered the earth's atmosphere "over the Gulf of Mexico between Cancun and Cuba," Friday afternoon. "This was within the previous prediction window but a little to the northeast of the 'most likely' part of the path."

From Space.com: The multi-ton Exposed Pallet 9 (EP9) was jettisoned from the space station back in March 2021. At the time, it was reported to be the most massive object ever tossed overboard from the International Space Station. Disposing of used or unnecessary equipment in such a way is common practice aboard the space station, as the objects typically burn up harmlessly in Earth's atmosphere.

Ahead of EP9's reentry, the Federal Office for Civil Protection and Disaster Relief, National Warning Center 1 in Bonn, Germany issued this information... "The object is battery packs from the International Space Station. Luminous phenomena or the perception of a sonic boom are possible...." EP9 is loaded with old Nickel-Hydrogen batteries, NASA explained at the time it was jettisoned, also explaining that EP9 has the approximate mass of a large SUV and predicting it would re-enter Earth's atmosphere in two-to-four years.

"A large space object reenters the atmosphere in a natural way approximately once per week," the European Space Agency points out, "with the majority of the associated fragments burning up before reaching the ground.

"Most spacecraft, launch vehicles and operational hardware are designed to limit the risks associated with a reentry."

Astronomers Detect 'Waterworld With a Boiling Ocean' in Deep Space (theguardian.com) 25

Astronomers have observed a distant planet that could be entirely covered in a deep water ocean, in findings that advance the search for habitable conditions beyond Earth. From a report: The observations, by Nasa's James Webb space telescope (JWST), revealed water vapour and chemical signatures of methane and carbon dioxide in the atmosphere of the exoplanet, which is twice Earth's radius and about 70 light years away. This chemical mix is consistent with a water world where the ocean would span the entire surface, and a hydrogen-rich atmosphere, according to researchers from the University of Cambridge, although they do not envisage a balmy, inviting seascape. "The ocean could be upwards of 100 degrees [Celsius] or more," said Prof Nikku Madhusudhan, who led the analysis. At high atmospheric pressure, an ocean this hot could still be liquid, "but it's not clear if it would be habitable," he added.

This interpretation is favoured in a paper published in the journal Astronomy and Astrophysics Letters, but is disputed by a Canadian team that made additional observations of the same exoplanet, which is known as TOI-270 d. They detected the same atmospheric chemicals but argue the planet would be too hot for liquid water -- possibly 4,000C -- and instead would feature a rocky surface topped by an incredibly dense atmosphere of hydrogen and water vapour. Whichever view wins out, these latest observations showcase the stunning insights James Webb is giving into the nature of planets beyond our solar system. The telescope captures the starlight that has been filtered through the atmospheres of orbiting planets to give detailed breakdowns of the chemical elements present. From this, astronomers can build up a picture of conditions at a planet's surface -- and the likelihood of life being able to survive there.

After Astra Loses 99% of Its Value, Founders Take Rocket Firm Private 13

Astra Space, a California-based rocket company, has announced it will go private at a valuation significantly lower than its $2.1 billion debut in 2021. The company's market value is about $13 million at current levels. The company's co-founders, Chris Kemp and Adam London, will acquire all outstanding shares at $0.50 each, well below the current trading price of $0.80. Astra has faced challenges, with only two successful launches out of seven attempts of its Rocket 3 vehicle. The company pivoted to the larger Rocket 4 in 2022 but has yet to conduct test launches.

Astra faces competition from established players like Rocket Lab and Firefly, as well as new entrants such as ABL Space and Stoke Space. The company's future remains uncertain as it navigates a competitive small launch market, with SpaceX's Transporter missions offering lower prices by launching dozens of satellites simultaneously on its Falcon 9 booster.

Voyager 1, First Craft in Interstellar Space, May Have Gone Dark (nytimes.com) 80

The 46-year-old probe, which flew by Jupiter and Saturn in its youth and inspired earthlings with images of the planet as a "Pale Blue Dot," hasn't sent usable data from interstellar space in months. From a report: When Voyager 1 launched in 1977, scientists hoped it could do what it was built to do and take up-close images of Jupiter and Saturn. It did that -- and much more. Voyager 1 discovered active volcanoes, moons and planetary rings, proving along the way that Earth and all of humanity could be squished into a single pixel in a photograph, a "pale blue dot," as the astronomer Carl Sagan called it. It stretched a four-year mission into the present day, embarking on the deepest journey ever into space. Now, it may have bid its final farewell to that faraway dot.

Voyager 1, the farthest man-made object in space, hasn't sent coherent data to Earth since November. NASA has been trying to diagnose what the Voyager mission's project manager, Suzanne Dodd, called the "most serious issue" the robotic probe has faced since she took the job in 2010. The spacecraft encountered a glitch in one of its computers that has eliminated its ability to send engineering and science data back to Earth. The loss of Voyager 1 would cap decades of scientific breakthroughs and signal the beginning of the end for a mission that has given shape to humanity's most distant ambition and inspired generations to look to the skies.

Satellite To 'Name and Shame' Worst Oil and Gas Methane Polluters (theguardian.com) 53

A washing-machine-sized satellite is to "name and shame" the worst methane polluters in the oil and gas industry. From a report: MethaneSat will provide the first near-comprehensive global view of leaks of the potent greenhouse gas from the oil and gas sector, and all of the data will be made public. It will provide high-resolution data over wider areas than existing satellites. Methane, also called natural gas, is responsible for 30% of the global heating driving the climate crisis. Leaks from the fossil fuel industry are a major source of human-caused emissions and stemming these is the fastest single way to curb temperature rises.

MethaneSat was developed by the Environmental Defense Fund, a US NGO, in partnership with the New Zealand Space Agency and cost $88m to build and launch. Earlier EDF measurements from planes show methane emissions were 60% higher than calculated estimates published by US authorities and elsewhere. More than 150 countries have signed a global methane pledge to cut their emissions of the gas by 30% from 2020 levels by 2030. Some oil and gas companies have made similar pledges, and new regulations to limit methane leaks are being worked on in the US, EU, Japan and South Korea.

The EDF's senior vice-president, Mark Brownstein, said: "MethaneSat is a tool for accountability . I'm sure many people think this could be used to name and shame companies who are poor emissions performers, and that's true. But [it] can [also] help document progress that leading companies are making in reducing their emissions." The oil and gas industry knows how to stop leaks and the cost of doing so is usually very modest, said Steven Hamburg, the EDF's chief scientist and MethaneSat project leader: "Some call it low hanging fruit. I like to call it fruit lying on the ground."

Warner Bros. Discusses 'Volatile' AAA Console Games, Will Lean Into Free-To-Play And Mobile (gamespot.com) 47

During a recent Morgan Stanley conference, Warner Bros. Discovery gaming boss J.B. Perrette discussed some of the company's strategy for gaming going forward, and it includes more live-service, mobile, and free-to-play games. From a report: He said, "We're doubling down on games as an area where we think there is a lot more growth opportunity that we can tap into with the IP that we have and some of the capabilities we have on the studio where we're uniquely positioned as both a publisher and a developer of games."

Perrette said WBD's recent gaming output has focused on AAA games for console, and that's great when a game like Hogwarts Legacy sells 22 million copies and becomes the best-selling game of the year, but this kind of success is never guaranteed in what Perrette said was a "volatile" market. He pointed out that one of WBD's latest big games, Suicide Squad: Kill the Justice League, was a disappointment for the company.

So the plan going forward, he said, is to help reduce volatility by focusing on core franchises and bringing at least some of them to the mobile and free-to-play space, as well as continuing to invest in live-service games that people play--and spend money on--over a long period of time. This will help WBD generate more consistent revenue, he said, going on to tease that WBD had some new mobile free-to-play games coming this year. Also worth noting is that just because WBD may push into new places, that doesn't necessarily mean it will stop making big single-player AAA games.

Airlines Are Coming for Your Carry-Ons 277

Carriers have gotten stricter about how many items you can take on board, no matter how small they are. From a report: Fanny packs. Cross-body bags. Shopping bags. Pillows and blankets. The Southwest Airlines gate agent rattled off so many items that counted toward the two carry-on bag limit on my flight to Baltimore, I thought it might be a playful jab at Spirit and Frontier and their rigid carry-on policing to collect more fees. But this was no joke. Southwest quietly began cracking down on carry-on bags on Feb. 22, ahead of the spring and summer travel rush, advising gate agents of the changes in a memo. This crackdown isn't about bag size. It is about how many bags you have.

Southwest isn't alone in putting passengers' personal items in its crosshairs as a way to save precious bin space and speed up boarding. Delta and United agents have also recently asked me to stuff my small Lululemon bag in my backpack. One American Airlines frequent flier told me he watched gate agents in Sacramento, Calif., and Dallas list a litany of items that count as a personal item on weekend flights to Nashville, Tenn., last month. Carting all your stuff to the gate can save you time and often saves money, especially with some airlines' new, higher checked-baggage fees. Delta joined the club on Tuesday, announcing prices of $35 for your first bag and $45 for your second. But testing airlines' carry-on limits is now more likely to backfire, and lose you precious time as airlines make you consolidate items or check a bag at the gate.
