After 64 years of service, ULA on Tuesday launched its last-ever Delta rocket carrying a classified payload for the U.S. National Reconnaissance Office (NRO). "The powerful booster departed Space Launch Complex-37 (SLC-37) at Cape Canaveral Space Force Station in Florida at 12:53 p.m. EDT (1653 GMT), literally setting itself on fire for the 16th and final time," reports Space.com. From the report: That spectacle, which was unique to the Delta IV in its heaviest configuration, was the result of hydrogen building up in the flame trench and then rising up alongside the rocket after it was used to cool down the three RS-68A engines to cryogenic temperatures. When the engines fired, the hydrogen ignited and flames lapped at the orange insulation covering the core stage and its two side-mounted boosters. The two boosters were jettisoned about four minutes into the flight, followed by the core, or first stage, separating one minute and 45 seconds later. A single RL10C-2-1 engine on the Delta cryogenic second stage then took over, propelling the NROL-70 payload into space. Due to national security concerns, coverage of the launch ceased following fairing jettison at about 6 minutes and 40 seconds into the flight.

ULA is retiring the Delta IV, and eventually its other legacy rocket, the Atlas V, in favor of its newly introduced Vulcan, which flew a near-perfect first mission in January. The Vulcan was developed to replace both long-flying rockets in all of their configurations. "This is a great mission to think about that transition, because national security space missions is our core and the unique set of missions there require a high-energy launch vehicle. We designed Vulcan specifically for that," said [Tory Bruno, chief executive officer of United Launch Alliance]. In addition to being the 16th Delta IV Heavy, Tuesday's launch was also the 45th liftoff of a Delta IV, the 35th Delta IV to fly from Florida and the 389th Delta launch of any kind since 1960 (of which 294 were sent skyward from Cape Canaveral). Half of the Delta IV Heavy launches were devoted to sending NRO payloads into orbit. The rocket and its less powerful configurations were also used in support of NASA, NOAA (the U.S. National Oceanic and Atmospheric Administration), U.S. Air Force and commercial payloads.

We're seeing a boom in journaling apps as safer, easier ways to ease us back into posting everything online. From a report: Last year, Apple released a journal app with iOS 17. Former Yahoo CEO Marissa Mayer just unveiled a photo app called Shine, which is made to share photos and memories with a select group of people. Today, Retro -- a startup that we called "the new Instagram" -- is launching a feature called Journals within the app, which lets you record both photos and notes for a select group of people.

As a lifelong journaler, it's hard to forget that I already have an intimate, safe space to record my life and share memories. It is a notebook. I don't have to worry about marketers selling my information, because it's not accessible. What if creating a safe space all of your own means just getting off the internet altogether? Most of these apps are based on the central premise that most of us would rather talk to family or close friends than with a pretty stranger shilling snack boxes. As we reported previously, Retro has a few standout features. Once you join the app, you're prompted to select a few pictures to post per week. In order to see your friends' and family's photos, you have to share photos of your own. That keeps people actively participating instead of lurking.

"Varda Space Industries has closed a massive tranche of funding," reports TechCrunch, "just weeks after its first drug manufacturing capsule returned from orbit."

Varda has now raised $145 million to date, the article points out, and the $90 million in new Series B funding "marks an inflection point for the company, which is now gearing up to scale from the initial demonstration mission to a regular set of missions carrying customer payloads, Varda founder Delian Asparouhov told TechCrunch." El Segundo-based Varda was founded in 2021 by Asparouhov, who is also a partner at Founders Fund, and Will Bruey, a spacecraft engineer who cut his teeth at SpaceX. The pair had an audacious goal to commercialize what until very recently was promising but ultimately small-scale research into the effects of microgravity on pharmaceutical crystals... Astronauts have been conducting protein crystallization experiments in space for decades on the International Space Station and before that, the Space Shuttle. But the business case for expanding this research has never materialized — until now...

Part of the reason Varda is possible today is due to the availability of regular, low-cost rideshare launches from SpaceX and Rocket Lab's innovations in satellite bus manufacturing. Even beyond these external partnerships, the startup has made significant headway in its own right, as the success of the first mission showed: Their reentry capsule appears to have performed flawlessly and the experiment to reformulate the HIV medicine ritonavir was executed without a hitch, it says. Varda has also started publishing the results of its internal R&D efforts, including a scientific paper on its hyper-gravity (as opposed to microgravity) crystallization platform, which the startup developed as a sort of screening method prior to sending drugs to space. [The paper is titled "Gravity as a Knob for Tuning Particle Size Distributions of Small Molecules."] It's an entirely new field of research that takes advantage of the ability to truly unlock gravity as a variable in scientific experiments. "Over time, we will be able to generate data sets between both hyper-gravity and microgravity and start to show correlations," he said....

In a recent podcast appearance, he specified that the all-in initial mission cost around $12 million, which will drop to $5-6 million by mission 4 and $2.5 million or less by mission 10.) Larger capsules are also in the longer-term pipeline, though also not until the 2027 time frame. Asparouhov also confirmed that pharmaceuticals will be Varda's sole focus for the next 10-20 (or more) years, based on the company's conviction that pharmaceutical products will generate more economic value compared to other materials. A lot of that comes down to the fact that there are a significant set of drugs that require only a "seed" of the material that can only be made in microgravity, and the rest of the drug formulation can be completed here on Earth...

The company is also aiming to improve the processing capabilities of the on-board pharmaceutical reactor. The first mission carried just one drug protein, but in the future the company hopes to process multiple drug products that could be run through different processing regimes. In the future, other missions could carry larger reactors for drugs that do need more than the "seed" crystal, and those mission profiles would be closer to something like mass manufacturing.
Varda already has "a handful" of signed contracts with biotech companies, according to the article — and Varda's next manufacturing mission "will launch later this year."

CNN revisits 2003's disastrous landing of the Space Shuttle Columbia tonight with two "immersive" specials co-produced by BBC and Mindhouse Productions "featuring exclusive interviews and revealing never-before-broadcast footage," according to an announcement — with two more specials airing next week.

You can watch a trailer here. Across four episodes, the story of the ticking-clock of Columbia's final mission is told in dramatic detail, beginning months before the troubled launch, unfolding across the sixteen days in orbit, and concluding with the investigation into the tragic loss of the seven astronauts' lives. Weaving together intimate footage shot by the astronauts themselves inside the orbiter, exclusive first-hand testimony from family members of the Shuttle's crew, key players at NASA — some of whom have never spoken before — and journalists who covered the story on the ground, the series paints an intimate portrait of the women and men onboard and uncovers in forensic detail the trail of events and missed opportunities that ultimately led to disaster.
CNN says the first two episodes will livestream tonight at 9 p.m. EST (time-delayed on the west coast until 9 p.m.PST) — and then be available on-demand starting Monday — "for pay TV subscribers via CNN.com, CNN connected TV and mobile apps." CNN's web site offers a "preview" of its live TV offerings here.

They're promising "the inside story of one America's most iconic institutions, uncovering how financial pressures and a culture of complacency may have contributed to the events of February 1, 2003. The series also reflects on the legacy of the Space Shuttle era, serving as a timely exploration of the challenges and inherent dangers that remain relevant to space travel today."

On its web site CNN has also published two companion articles — one by Rice history professor Douglas Brinkley arguing that NASA "was America's crown jewel. After the Columbia disaster it was never quite the same." Because other shuttle missions had returned safely with "shredded" surface tiles — and because the stalwart Columbia had brought astronauts home from 27 previous flights — many NASA officials were lulled into complacency. They went so far as to assure the pilot and commander via email that "there is no concern ... We have seen the same phenomenon on several other flights and there is absolutely no concern for entry."

NASA officials also decided against enlisting spy satellite photography to examine the shuttle damage more thoroughly. If they had, it's possible that the astronauts could have repaired the spaceplane or at least abandoned it for refuge on the International Space Station...

As the Columbia Accident Investigation Board (CAIB) noted in its final report, "the NASA organizational culture had as much to do with this accident as the foam." All of NASA's launches were suspended for two years. While the shuttles eventually flew again, post-Columbia, the program was stunted and curtailed.
The article notes that since then SpaceX, Blue Origin, and the United Launch Alliance (Lockheed Martin and Boeing) "are thriving today in the space industry," along with Virgin Galactic and Axiom Space. "NASA, far from feeling threatened, has encouraged many of the private companies with massive contracts. The agency already had a long history of dealing with sub-contractors, using its pocketbook to steer aerospace development; that tradition has adjusted seamlessly to the current space economy."

In the other article CNN Space & Science writer Jackie Wattles notes that when America later retired its Space Shuttle program in 2011, "no U.S. astronaut would travel to space on an American-made rocket for nearly a decade."

The European Space Agency has a Planetary Defence Office, which includes its Near-Earth Object Coordination Centre. "It has come to our attention," they wrote in the April edition of their monthly newsletter, "that a recent trend among journalists has been to come up with creative comparisons to convey the size of an asteroid to the public."

So then, as explained by RockDoctor (Slashdot reader #15,477) "they propose a number of standardised units of comparison for journalists describing 'death from the skies'".

An excerpt from that April 1 newsletter: In the absence of a handy skyscraper, animals commonly used have included giraffes, corgis and an entire colony of penguins. But how do these comparisons stack up? Let's look at some of our favourite unusual suspects:

- Corgi: At around 30 cm tall, a space rock the size of a corgi wouldn't pose much of a threat.

- Half a giraffe: An adult giraffe can reach up to 5.5 metres in height, so half a giraffe would be about 2.75 metres. While not as impressive as a full skyscraper, an asteroid that size could certainly destroy a building or two...

- Elephants: An adult African elephant can reach 7 metres at the shoulder. Ninety elephants stacked on top of each other would form a staggering pile over 630 metres high, creating a devastating but probably not planet-ending event.

As this menagerie of animals can cause a lot of confusion, we at the NEOCC recommend the use of a Standardised Giraffe Unit (SGU, 1 SGU = 5 penguins) for ease of comparison.
RockDoctor shares this additional thought in his original submission about the newly proposed standardized unit.

"The world may be turtles all the way down, but it's giraffes all the way up."

NASA engineers have traced the Voyager 1 spacecraft's transmitted gibberish to corrupted memory hardware in its flight data system (FDS). "The team suspects that a single chip responsible for storing part of the affected portion of the FDS memory isn't working," NASA wrote in an update. Gizmodo reports: FDS collects data from Voyager's science instruments, as well as engineering data about the health of the spacecraft, and combines them into a single package that's transmitted to Earth through one of the probe's subsystems, the telemetry modulation unit (TMU), in binary code. FDS and TMU have been having trouble communicating with one another. As a result, TMU has been sending data to mission control in a repeating pattern of ones and zeroes. NASA's engineers aren't quite sure what corrupted the FDS memory hardware; they think that either the chip was hit by an energetic particle from space or that it's just worn out after operating for 46 years. [...] The engineers are hoping to resolve the issue by finding a way for FDS to operate normally without the corrupted memory hardware, enabling Voyager 1 to begin transmitting data about the cosmos and continue its journey through deep space.

Whenever a rocket launch occurs, air traffic controllers ensure the safety of commercial flights by managing airspace closures and monitoring rocket debris, without receiving compensation from commercial space companies like SpaceX for these services. The Biden administration's budget proposal aims to change this by suggesting that for-profit space companies begin paying for their use of government air traffic control resources. The New York Times reports: Commercial space companies are exempt from aviation excise taxes that fill the coffers of the Airport and Airway Trust Fund, which pays for the F.A.A.'s work and will get roughly $18 billion in tax revenues for the current fiscal year. The taxes are paid primarily by commercial airlines, which are charged 7.5 percent of each ticket price and an additional fee of about $5 to $20 per passenger, depending on the destination of each flight. Mr. Biden's budget proposal vows to work with Congress to overhaul the tax structure and split the cost of operating the nation's air traffic control system. His promise is based in part on an independent safety review report commissioned by the F.A.A., which advises that the federal government update the excise taxes to charge commercial space companies.

Mr. Biden's call for revising the decades-old excise tax structure is part of his push to make richer Americans and wealthy corporations "pay their fair share." In his State of the Union speech last month, Mr. Biden also called for raising taxes on private and corporate jet users, including increasing the tax that they pay on jet fuel to $1.06 per gallon from 21.8 cents per gallon over five years. That tax on fuel currently makes up around 3 percent of the annual revenue of the trust fund, which depends heavily on what commercial airlines and its passengers pay. Yet commercial space companies do not contribute to that fund or share any of the cost that the public bears when rockets are launched, said William J. McGee, a former F.A.A.-licensed aircraft dispatcher and a senior fellow at the American Economic Liberties Project, a consumer advocacy group. "This is a question of fundamental fairness," Mr. McGee said. "It would be the equivalent of having a toll system on a highway and waving through certain users and not others."

An anonymous reader quotes a report from Kotaku: A new patent recently filed by TV and streaming device manufacturer Roku hints toward a possible future where televisions could display ads when you pause a movie or game. For Roku, the time in which the TV is on but users aren't doing anything is valuable. The company has started leasing out ad space in its popular Roku City screensaver -- which appears when your TV is idle -- to companies like McDonald's and movies like Barbie. As tech newsletter Lowpass points out, Roku finds this idle time and its screensaver so valuable that it forbids app developers from overriding the screensaver with their own. But, if you plug in an Xbox or DVD player into the HDMI port on a Roku TV, you bypass the company's screensaver and other ads. And so, Roku has been figuring out a way to not let that happen.

As reported by Lowpass on April 4, Roku recently filed a patent for a technology that would let it inject ads into third-party content -- like an Xbox game or Netflix movie -- using an HDMI connection. The patent describes a situation where you are playing a video game and hit pause to go check your phone or grab some food. At this point, Roku would identify that you have paused the content and display a relevant ad until you unpaused the game. Roku's tech isn't designed to randomly inject ads as you are playing a game or watching a movie, it knows that would be going too far and anger people. Instead, the patent suggests several ways that Roku could spot when your TV is paused, like comparing frames, to make sure the user has actually paused the content. Roku might also use the HDMI's audio feed to search for extended moments of silence. The company also proposes using HDMI CEC -- a protocol designed to help devices communicate better -- to figure out when you pause and unpause content. Similarly, Roku's patent explains that it will use various methods to detect what people are playing or watching and try to display relevant ads. So if it sees you have an Xbox plugged in, it might try to serve you ads that it thinks an Xbox owner would be interested in.

Google has introduced a new JPEG library called Jpegli, which reduces noise and improves image quality over traditional JPEGs. Proponents of the technology said it has the potential to make the Internet faster and more beautiful. InfoWorld reports: Announced April 3 and accessible from GitHub, Jpegli maintains high backward compatibility while offering enhanced capabilities and a 35% compression ratio at high-quality compression settings, Google said. Jpegli works by using new techniques to reduce noise and improve image quality. New or improved features include adaptive quantization heuristics from the JPEG XL reference implementation, improved quantization matrix selection, calculation of intermediate results, and the possibility to use more advanced colorspace.

The library provides an interoperable encoder and decoder complying with the original JPEG standard and its most convenient 8-bit formalism and API/ABI compatibility with libjeg-turbo and MozJPEG. When images are compressed or decompressed through Jpegli, more precise and psycho-visually effective computations are also performed; images will look clearer and have fewer observable artifacts. While improving on the density ratio of image quality and compression, Jpegli's coding speed is comparable to traditional approaches such as MozJPEG, according to Google. Web developers can thus integrate Jpegli into existing workflows without sacrificing coding speed, performance, or memory use.

Jpegli can be encoded with 10-plus bits per component. The 10-bit encoding happens in the original 8-bit formalism and the resulting images are interoperable with 8-bit viewers. The 10-bit dynamics are available as an API extension and application code changes are necessary to apply it. Also, Jpegli compresses images more efficiently than traditional JPEG codecs; this can save bandwidth and storage space and make web pages faster, Google said.

An anonymous reader writes: In the early 70s, young filmmakers John Carpenter and Dan O'Bannon created a spaceship tale for a graduation project -- little knowing it would influence Alien and many other works. Made for $60,000 by film school students, horror maestro John Carpenter's directorial debut Dark Star is now regarded as a sci-fi cult classic. Having just turned 50 years old, it's a world away from much of the sci-fi that came before it and would come after, neither space odyssey nor space opera, rather a bleak, downbeat and often absurd portrait of a group of people cooped together in a malfunctioning interstellar tin can. Arguably its most famous scene consists of an existential debate between an astronaut and a sentient bomb. Dark Star was a collaboration between Carpenter, who directed and scored the film, and Dan O'Bannon, who in addition to co-writing the script, acted as editor, production designer, and visual effects supervisor, as well as playing the volatile, paranoid Sergeant Pinback. They met as budding filmmakers at the University of Southern California. "While [Carpenter and O'Bannon] couldn't be more dissimilar in personality, they were both very energetic and focused," says Daniel Griffiths, director of Let There Be Light: The Odyssey of Dark Star (2010), the definitive documentary about the making of the film.

The sci-fi films of this period tended to be bleak and dystopian, explains John Kenneth Muir, author of The Films of John Carpenter -- films like Silent Running (1972), in which all plant life on Earth is extinct, or George Lucas's 1971 debut THX-1138, in which human emotion is suppressed. "Dark Star arrived in this world of dark, hopeless imaginings, but took the darkness one step further into absurd nihilism." Carpenter and O'Bannon set out to make the "ultimate riff on Stanley Kubrick's 2001: A Space Odyssey," says Griffiths. While Kubrick's 1968 film, explains Muir, was one "in which viewers sought meaning in the stars about the nature of humanity, there is no meaning to life in Dark Star". Rather, says Muir, it parodies 2001 "with its own sense of man's irrelevance in the scheme of things". Where Kubrick scored his film with classical music, Dark Star opens with a country song, Benson, Arizona. (A road in the real-life Benson is named in honor of the film). The film was even released with the tagline "the spaced-out odyssey." Dark Star captured the mood of the time in which it was made, says Muir, the atmosphere of Nixon's America. "The 1960s was all about utopian dreaming and bringing change to America in the counterculture. The 1970s represent what writer Johnny Byrne called 'The wake-up from the hippie dream', a reckoning with the fact that the more things change, the more they stay the same." [...]

When Dark Star premiered at the FILMEX expo in 1974, the audience response was largely positive. "They recognized the film's absurdist humor and celebrated its student film roots," says Griffiths. It had a limited theatrical release in 1975, but it was not a commercial success. "The film met with negative reviews from critics, and general disinterest from audiences," says Muir. "Both Carpenter and O'Bannon realized that all the struggles they endured to make the film did not matter to audiences, they only cared about the finished product. I think they were discouraged," says Griffiths. The growth of the VHS market, however, helped it find its audience and propelled it towards cult status. Its influence can still be felt, perhaps most directly in Ridley Scott's Alien, for which O'Bannon, who died in 2009, wrote the screenplay. The two films share DNA. Alien is also set on a grotty working vessel with a bickering crew, only this time the alien wasn't played for laughs.

The biggest ever 3D map of the universe, featuring more than 6m galaxies, has been revealed by scientists who said it raised questions about the nature of dark energy and the future of the universe. From a report: The map is based on data collected by the Dark Energy Spectroscopic Instrument (Desi) in Arizona and contains three times as many galaxies as previous efforts, with many having their distances measured for the first time. Researchers said that by using this map, they have been able measure how fast the universe has been expanding at different times in the past with unprecedented accuracy.

The results confirm that the expansion of the universe is speeding up, they added. However, the findings have also raised the tantalising possibility that dark energy -- a mysterious, repulsive force that drives the process -- is not constant throughout time as has previously been suggested. Dr Seshadri Nadathur, a co-author of the work and senior research fellow at the University of Portsmouth's Institute of Cosmology and Gravitation, said: "What we are seeing are some hints that it has actually been changing over time, which is quite exciting because it is not what the standard model of a cosmological constant dark energy would look like."

Prof Carlos Frenk, from Durham University and a co-author of the research, said that if dark energy was indeed constant in time, the future of the universe was simple: it would expand on and on, for ever. But if the hints found in the map stood up, that would be called into question. The research, which has been published in a series of preprints â" meaning it has yet to be peer-reviewed â" reveals how the team first created the 3D map, then measured patterns in the distribution of galaxies that relate to sound waves that occurred in the early universe, known as baryon acoustic oscillations.

SonicSpike shares a report from Scientific American: A day after the American Astronomical Society (AAS) announced that there were no signs of unsafe eclipse glasses or other solar viewers on the market in early March, astronomer and science communicator Rick Fienberg received an alarming call. Fienberg is project manager of the AAS Solar Eclipse Task Force, which is busy preparing for the total eclipse over North America on April 8. He's the creator of a list of vetted solar filters and viewers that will protect wearers' eyes as they watch the moon move in front of the sun. When a solar eclipse last crossed a major swath of the U.S. in 2017, Fienberg and his team spotted some counterfeit glasses entering the marketplace -- imitations that distributors claimed were manufactured by vetted companies. Testing at accredited labs indicated that many counterfeits were actually safe to use, however. This led the task force to describe such eclipse glasses as "misleading" but not "dangerous" in a March 11 statement meant to reassure the public.

But then Fienberg's phone rang. The caller was "a guy who had bought thousands of eclipse glasses from a distributor who had been on our list at one point," Fienberg says. "Those glasses were not safe. They were no darker than ordinary sunglasses." Legitimate eclipse glasses are at least 1,000 times darker than the darkest sunglasses you can buy. Fienberg contacted Cangnan County Qiwei Craft, a Chinese factory that he knew manufactured safe glasses and had -- in the past -- sold them to the distributor in question. But this time, Fienberg says, factory representatives told him they hadn't sold to that distributor in a long while. "That's when we switched from being concerned about only counterfeits to being concerned about actual fakes," Fienberg says. The AAS does not have a confident estimate of how many fake or counterfeit glasses are for sale out there. And though Fienberg doesn't think this is a widespread problem, the situation is an "iceberg kind of concern," he says, because there are likely more examples than the ones he knows about. While counterfeit glasses may still be safe to use, completely fake glasses could put wearers in serious danger. [...]

While lab tests are the best way to determine whether glasses meet the ISO standard, Fienberg says there is a three-part test people can do at home if they're concerned their eclipse viewers aren't up to the task. First, put your glasses on indoors and look around. The only things you should be able to see are very bright lights, such as a halogen bulb or a smartphone flashlight. Then, if the glasses pass the indoor test, bring them outside -- but don't look at the sun just yet. Look around: it should be too dark to see distant hills, trees or even the ground. If that second test is passed, keep the glasses on and quickly glance at the sun. You should comfortably see a bright, sharp-edged round disk. If your glasses pass all three tests, they are probably safe to wear. Still, Fienberg points out that it's best to use them for only a few seconds every minute or so during the eclipse; this cautious approach is how they're intended to be used. And if you don't trust your glasses for April's celestial event, you could try to find a reliable pair in the next two decades. "You only have to wait 20 years for another really good eclipse year in the [United] States," Fienberg says.

NASA announced on Wednesday that they have selected three companies to develop preliminary designs for vehicles to take astronauts around the south polar region of the Moon. "After the astronauts return to Earth, these vehicles would be able to self-drive around as robotic explorers, similar to NASA's rovers on Mars," reports the New York Times. "The self-driving capability would also allow the vehicle to meet the next astronaut mission at a different location." From the report: The companies are Intuitive Machines of Houston, which in February successfully landed a robotic spacecraft on the moon; Lunar Outpost of Golden, Colo.; and Venturi Astrolab of Hawthorne, Calif. Only one of the three will actually build a vehicle for NASA and send it to the moon. NASA had asked for proposals of what it called the lunar terrain vehicle, or L.T.V., that could drive at speeds up to 9.3 miles per hour, travel a dozen miles on a single charge and allow astronauts to drive around for eight hours. The agency will work with the three companies for a year to further develop their designs. Then NASA will choose one of them for the demonstration phase. The L.T.V. will not be ready in time for the astronauts of Artemis III, the first landing in NASA's return-to-the-moon program, which is currently scheduled for 2026.

The plan is for the L.T.V. to be on the lunar surface ahead of Artemis V, the third astronaut landing that is expected in 2030, said Lara Kearney, manager of the extravehicular activity and human surface mobility program at the NASA Johnson Space Center. "If they can get there earlier, we'll take it earlier," Ms. Kearney said. The L.T.V. contract will be worth up to $4.6 billion over the next 15 years -- five years of development and then a decade of operations on the moon, most of it going to the winner of this competition. But Ms. Kearney said the contracts allow NASA to later finance the development of additional rovers, or allow other companies to compete in the future.

Isaac Schultz reports via Gizmodo: Nine years and 3.2 billion pixels later, it is complete: the LSST Camera stands as the largest digital camera ever built for astronomy and will serve as the centerpiece of the Vera Rubin Observatory, poised to begin its exploration of the southern skies. The Rubin Observatory's key goal is the 10-year Legacy Survey of Space and Time (LSST), a sweeping, near-constant observation of space. This endeavor will yield 60 petabytes of data on the composition of the universe, the nature and distribution of dark matter, dark energy and the expansion of the universe, the formation of our galaxy, our intimate little solar system, and more. The camera will use its 5.1-foot-wide optical lens to take a 15-second exposure of the sky every 20 seconds, automatically changing filters to view light in every wavelength from near-ultraviolet to the near-infrared. Its constant monitoring of the skies will eventually amount to a timelapse of the heavens; it will highlight fleeting events for other scientists to train their telescopes on, and monitor changes in the southern sky.

To do this, the team needed a Rolls Royce of a digital camera. Mind you, the camera actually cost many million times that of an actual Royce Royce, and at 6,200 pounds (2,812 kilograms), it weighs a lot more than a fancy car. Each of the 21 rafts that makes up the camera's focal plane is the price of a Maserati, and are worth every penny if they collect the sort of data scientists expect them to. "I'm personally most excited to study the expansion of the Universe using gravitational lenses to better understand Dark Energy," said Aaron Roodman, a physicist at SLAC and lead on the camera program, in an email to Gizmodo. "That means two things: 1) measuring the brightness in all six of our filters of literally billions of galaxies and very carefully measuring their shape, which has been subtly altered by the bending of light by matter, and 2) discovering and studying very special objects where a distant quasar is almost perfectly lined up with a more nearby galaxy."

Speaking through a SLAC release, Rodman said the camera's images could "resolve a golf ball from around 15 miles away, while covering a swath of the sky seven times wider than the full moon." The first images from the Rubin Observatory are slated to be publicly released in March 2025, which feels like a long way away. But several important agenda items still need to happen. For one, the SLAC team has to ship the LSST camera safely to Chile from its current lodgings in northern California. (Don't worry -- they've made a test run of the journey.) Then, the observatory's mirrors need to be readied for testing and the observatory's dome has to be completed, among some other tasks. But whenever all that is complete, the legacy survey will launch into a decade's worth of scientific discovery. Rubin Observatory estimates suggest that LSST could "increase the number of known objects by a factor of 10," according to a SLAC release.

artmancc writes: The White House has directed NASA and other federal agencies to get to work on a plan to implement precision timekeeping and dissemination on the moon and elsewhere in space. Reuters cited a memo from the head of the White House Office of Science and Technology Policy (OSTP) that "instructed the space agency to work with other parts of the U.S. government to devise a plan by the end of 2026 for setting what it called a Coordinated Lunar Time (LTC). The name of the proposed time standard is similar to the terrestrial time standard known as Coordinated Universal Time (UTC).

"OSTP chief Arati Prabhakar's memo said that for a person on the moon, an Earth-based clock would appear to lose on average 58.7 microseconds per Earth-day and come with other periodic variations that would further drift moon time from Earth time," Reuters reported. An unidentified OSTP official said the lunar time standard is needed for secure and synchronized communication between astronauts, satellites orbiting the moon, and Earth.

A nearly two-pound piece of trash from the International Space Station may have hit a house in Florida. Alejandro Otero said it "tore through the roof and both floors of his two-story house in Naples, Florida," reports Ars Technica. "Otero wasn't home at the time, but his son was there." From the report: A Nest home security camera captured the sound of the crash at 2:34 pm local time (19:34 UTC) on March 8. That's an important piece of information because it is a close match for the time -- 2:29 pm EST (19:29 UTC) -- that US Space Command recorded the reentry of a piece of space debris from the space station. At that time, the object was on a path over the Gulf of Mexico, heading toward southwest Florida. This space junk consisted of depleted batteries from the ISS, attached to a cargo pallet that was originally supposed to come back to Earth in a controlled manner. But a series of delays meant this cargo pallet missed its ride back to Earth, so NASA jettisoned the batteries from the space station in 2021 to head for an unguided reentry.

Otero's likely encounter with space debris was first reported by WINK News, the CBS affiliate for southwest Florida. Since then, NASA has recovered the debris from the homeowner, according to Josh Finch, an agency spokesperson. Engineers at NASA's Kennedy Space Center will analyze the object "as soon as possible to determine its origin," Finch told Ars. "More information will be available once the analysis is complete." [...] In a post on X, Otero said he is waiting for communication from "the responsible agencies" to resolve the cost of damages to his home.

If the object is owned by NASA, Otero or his insurance company could make a claim against the federal government under the Federal Tort Claims Act, according to Michelle Hanlon, executive director of the Center for Air and Space Law at the University of Mississippi. "It gets more interesting if this material is discovered to be not originally from the United States," she told Ars. "If it is a human-made space object which was launched into space by another country, which caused damage on Earth, that country would be absolutely liable to the homeowner for the damage caused." This could be an issue in this case. The batteries were owned by NASA, but they were attached to a pallet structure launched by Japan's space agency.

An anonymous reader quotes a report from Android Police, written by Dhruv Bhutani: As someone who is an early adopter of all things smart and has invested a significant amount of money in building a fancy smart home, it saddens me to say that I feel cheated by the thousands of dollars I've spent on smart devices. And it's not a one-off. Amazon's recent move to block off local ADB connections on Fire TV devices is the latest example in a long line of grievances. A brand busy wrestling away control from the consumer after they've bought the product, the software update gimps a feature that has been present on the hardware ever since it launched back in 2014. ADB-based commands let users take deep control of the hardware, and in the case of the Fire TV hardware, it can drastically improve the user experience. [...] A few years ago, I decided to invest in the NVIDIA Shield. The premium streamer was marketed as a utopia for streaming online and offline sources with the ability to plug in hard drives, connect to NAS drives, and more. At launch, it did precisely that while presenting a beautiful, clean interface that was a joy to interact with. However, subsequent updates have converted what was otherwise a clean and elegant solution to an ad-infested overlay that I zoom past to jump into my streaming app of choice. This problem isn't restricted to just the Shield. Even my Google TV running Chromecast has a home screen that's more of an advertising space for Google than an easy way to get to my content.

But why stop at streaming boxes? Google's Nest Hubs are equal victims of feature deterioration. I've spent hundreds of dollars on Nest Hubs and outfitted them in most of my rooms and washrooms. However, Google's consistent degradation of the user experience means I use these speakers for little more than casting music from the Spotify app. The voice recognition barely works on the best of days, and when it does, the answers tend to be wildly inconsistent. It wasn't always the case. In fact, at launch, Google's Nest speakers were some of the best smart home interfaces you could buy. You'd imagine that the experience would only improve from there. That's decidedly not the case. I had high hopes that the Fuchsia update would fix the broken command detection, but that's also not the case. And good luck to you if you decided to invest in Google Assistant-compatible displays. Google's announcement that it would no longer issue software or security updates to third-party displays like the excellent Lenovo Smart Display, right after killing the built-in web browser, is pretty wild. It boggles my mind that a company can get away with such behavior.

Now imagine the plight of Nest Secure owners. A home security system isn't something one expects to switch out for many many years. And yet, Google decided to kill the Nest Secure home monitoring solution merely three years after launching the product range. While I made an initial investment in the Nest ecosystem, I've since switched over to a completely local solution that is entirely under my control, stores data locally, and won't be going out of action because of bad decision-making by another company. "It's clear to me that smart home devices, as they stand, are proving to be very poor investments for consumers," Bhutani writes in closing. "Suffice it to say that I've paused any future investments in smart devices, and I'll be taking a long and hard look at a company's treatment of its current portfolio before splurging out more cash. I'd recommend you do the same."

"Be it enacted by the Legislature of the State of Arizona..." reads the official text of House Bill #2,477. "PLUTO IS THE OFFICIAL STATE PLANET."

An anonymous reader shared this report from Capital Media Services: The governor signed legislation Friday designating Pluto as Arizona's "official state planet." It joins a list of other items the state has declared to be "official,'' ranging from turquoise as the state gemstone and copper as the state metal to the Sonorasaurus as the state dinosaur. "I am proud of Arizona's pioneering work in space discovery," governor Hobbs said.

What makes Pluto unique and ripe for claim by Arizona is that it is the only planet actually discovered in the United States, and the discovery was made in Flagstaff. Rep. Justin Wilmeth, a Phoenix Republican and self-described "history nerd,'' said that needed to be commemorated, starting with the legacy of astronomer Clyde Tombaugh. In 1930, Tombaugh was working at the Lowell Observatory in Flagstaff. "The whole story of Clyde is just amazing, just sitting there under the telescope'' looking for planets by taking photos over a period of time, said Wilmeth. "It was two different glass planes that had one little spec of light moving in a different direction,'' showing it wasn't just another star — and all by observation and not computers. "To me, that's something that's just mind boggling."
"The International Astronomical Union voted years ago to strip Pluto of its official status as a planet," the article points out, noting that its official definition specifies that planets "clear the neighboring region of other objects." (While Pluto "has such a small gravitational pull, it has not attracted and absorbed other space rocks in its orbit".)

So in 2006 Pluto was reclassified as a dwarf planet, according to a NASA web page. "Pluto is about 1/6 the width of Earth," and has a radius of 715 miles or 1,151 kilometers. "If Earth was the size of a nickel, Pluto would be about as big as a popcorn kernel."

Long-time Slashdot reader Baron_Yam called Arizona's new legislation "How to advertise you are ignorant. Scientists said something we don't like, so we'll make a law!" They can call it their "State Planet" all they want, but people who actually know about the skies will be mocking them for it. While there is nostalgia for the old classification, and the new one isn't perfect... it's certainly more meaningful when trying to divide up the objects of a planetary system for study.
Reached for a comment by Capital Media Services, Representative Wilmeth said "It might matter to some that are going to get picky or persnickety about stuff... There's several generations of Americans ... who believe that Pluto's a planet — or at least that's what we were taught. I'm never going to think differently. That's just my personal opinion." (The news site adds that "What is important, Wilmeth said, is remembering the history and promoting it.")

Five senators in Arizona's state legislatur did vote against the measure — though not all of them did so for scientific reasons, Senator Anthony Kern explained to Capital Media Services. "I did not want to discriminate against those who wanted Mars, Venus, Jupiter, or everyone's favorite, Uranus."

"Sail to a continent as mysterious as outer-space itself," the new web site urges.

"William Shatner saw Earth from the highest view," writes Scripps News Service. "Now he's heading to the bottom of it — and inviting you to join him." The 93-year-old is setting sail for Antarctica on Dec. 19, which will mark just over three years since the "Star Trek" actor returned from a trip to space in real life, not just as Captain James T. Kirk. Fellow space traveler NASA astronaut Scott Kelly will join Shatner on the 10-day Space2Sea expedition, and 260 others can too — if they pay for their $37,500 ticket.

The cheapest suite — priced at $35,500 — along with the top three most expensive ones — reaching $91,500 — are already sold out. Presented by Future of Space, the trip aboard the new "ultra-luxury" vessel is said to be full of "awe-inspiring experiences," including "intimate encounters" with penguins, visits to remote historical locations and evenings full of stories from "esteemed guests," like Shatner. Travelers can also kayak the waters or go down deep under the ice in submersibles, both for additional charges...

Shatner said he experienced something called the "overview effect" while viewing the Earth from space. The overview effect, coined by space philosopher and author Frank White, refers to a shift in how astronauts think about our life on the planet, described by White as "the feeling that the Earth itself is a whole system, and we're just a part of it." It's also realizing through experience that there are no borders or boundaries on Earth. It's often marked by feelings of increased appreciation of the planet's beauty. Shatner's invitation to "fellow explorers" for the Space2Sea expedition seem to echo this phenomenon, with the actor saying he didn't expect to be "captivated by the fragile, blue curve of our planet" when flying on Blue Origin's rocket.

"After being in development since 2019, the huge NetBSD 10.0 is out today as a wonderful Easter surprise," reports Phoronix: NetBSD 10 provides WireGuard support, support for many newer Arm platforms including for Apple Silicon and newer Raspberry Pi boards, a new Intel Ethernet drive, support for Realtek 2.5GbE network adapters, SMP performance improvements, automatic swap encryption, and an enormous amount of other hardware support improvements that accumulated over the past 4+ years.

Plus there is no shortage of bug fixes and performance optimizations with NetBSD 10. Some tests of NetBSD 10.0 in development back during 2020 showed at that point it was already 12% faster than NetBSD 9.
"A lot of development went into this new release," NetBSD wrote on their blog, saying "This also caused the release announcement to be one of the longest we ever did."

Among the new userspace programs is warp(6), which they describe as a "classic BSD space war game (copyright donated to the NetBSD Foundation by Larry Wall)."
