In 2018 a doctoral student spotted "a spinning celestial space object," reports CNN. "The unfamiliar object released giant bursts of energy and beamed out radiation three times per hour."

But that was just the beginning... In those moments, it became the brightest source of radio waves viewable from Earth through radio telescopes, acting like a celestial lighthouse. Researchers thought the phenomenon might be a remnant of a collapsed star — either a dense neutron star or a dead white dwarf star — with a strong magnetic field. Or perhaps the object was something else entirely... "We were stumped," said Dr. Natasha Hurley-Walker, senior lecturer at the Curtin University node of ICRAR, in a statement. "So we started searching for similar objects to find out if it was an isolated event or just the tip of the iceberg." The team observed the sky using the Murchison Widefield Array, a radio telescope on Wajarri Yamaji Country in outback Western Australia, between July and September 2022. The scientists discovered an object 15,000 light-years from Earth in the Scutum constellation. The object, dubbed GPM J1839-10, released radio waves every 22 minutes. The bursts of energy lasted up to five minutes.

Astronomers believe it could be a magnetar, or a rare type of star with extremely strong magnetic fields that is capable of releasing powerful, energetic bursts. But if the object is a magnetar, it defies description because all known magnetars release energy in a matter of seconds, or a few minutes at the most. A study detailing the discovery was published Wednesday in the journal Nature. "This remarkable object challenges our understanding of neutron stars and magnetars, which are some of the most exotic and extreme objects in the Universe," said Hurley-Walker, who was the lead author of the new report...

"Assuming it's a magnetar, it shouldn't be possible for this object to produce radio waves. But we're seeing them. And we're not just talking about a little blip of radio emission. Every 22 minutes, it emits a five-minute pulse of radio wavelength energy, and it's been doing that for at least 33 years. Whatever mechanism is behind this is extraordinary."
The astronomers "searched through the archives of radio telescopes that have been operational for decades," the article points out — and ultimately confirmed the existence of the phenomenon. "It showed up in observations by the Giant Metrewave Radio Telescope in India and the Very Large Array in the USA had observations dating as far back as 1988," Hurley-Walker said.

"That was quite an incredible moment for me. I was five years old when our telescopes first recorded pulses from this object, but no one noticed it, and it stayed hidden in the data for 33 years. They missed it because they hadn't expected to find anything like it."

Astranis, a geostationary communications satellite operator, successfully deployed its "Arcturus" satellite from a Falcon Heavy rocket in May to provide internet connectivity from geostationary space. However, the satellite experienced an unexpected issue with a supplier's component on the solar array drive assembly, affecting its ability to maintain continuous power. Ars Technica reports: "The Astranis engineering team has been doing an incredible job working around the clock to troubleshoot the issue," [Astranis co-founder John Gedmark] said. "We have now reproduced the problem on the ground in a vacuum chamber, zeroed in on the exact source of the failure, and know how to fix it for future spacecraft. Because this failure occurred within the internal workings of a component supplied by an external vendor, we're not in a position to go into the full technical details." The disappointment in Gedmark's update is palpable. "This is a frustrating situation -- the Arcturus spacecraft is in a safe state and fully under our control, the payload and our other Astranis in-house designed components are all working perfectly, and the tanks are fueled for years of on-orbit operation," he said. "But unless something major changes, the mission of providing Internet connectivity in Alaska will be delayed."

Astranis was founded in 2015 to determine whether microsatellites built largely in-house could deliver high-speed Internet from geostationary space at a low price. The launch of Arcturus marked the first demonstration that Astranis' small satellite technology worked in space and could survive the harsh radiation and thermal environment previously dominated by much larger satellites that cost hundreds of millions of dollars. Given that this was an effort to test this technology on a shoestring budget, it is perhaps not surprising that the satellite ultimately failed due to some unforeseen problem. The real acid test for Astranis, now, is to ensure that it learns from this failure and that the company's second satellite works in space.

In his update, Gedmark said the company understands how to quickly solve this issue on future spacecraft that are in production. The company is also working toward a solution to provide Internet service in Alaska, via Pacific Dataport, as initially planned with Arcturus. The backup plan, he said, "involves a special, multipurpose satellite that can operate as an on-orbit spare and bridge us to a full replacement satellite. We call this satellite UtilitySat. It can operate anywhere in the world, on multiple frequency bands, with the flexibility of a software-defined satellite. UtilitySat has been in the works for over a year, is in the final stages of integration, and is manifested on our very next launch that will take place at the end of this year."

Astronomers have discovered a two-faced star and are baffled by its bizarre appearance. The Guardian reports: The white dwarf appears to have one side composed almost entirely of hydrogen and the other side made up of helium. It is the first time that astronomers have discovered a lone star that appears to have spontaneously developed two contrasting faces. The object, which is more than 1,000 light years away in the Cygnus constellation, has been nicknamed Janus, after the two-faced Roman god of transition, although its formal scientific name is ZTF J203349.8+322901.1. It was initially discovered by the Zwicky Transient Facility (ZTF), an instrument that scans the skies every night from Caltech's Palomar Observatory near San Diego.

"The surface of the white dwarf completely changes from one side to the other," said Dr Ilaria Caiazzo, an astrophysicist at Caltech who led the work. "When I show the observations to people, they are blown away." Caiazzo was searching for white dwarfs and one candidate star stood out due to its rapid changes in brightness. Further observations revealed that Janus was rotating on its axis every 15 minutes. Spectrometry measurements, which give the chemical fingerprints of a star, showed that one side of the object contained almost entirely hydrogen and the other almost entirely helium. If seen up close, both sides of the star would be bluish in colour and have a similar brightness, but the helium side would have a grainy, patchwork appearance like that of our own sun, while the hydrogen side would appear smooth. The findings are published in the journal Nature.

Researchers have announced the discovery of an astronomical object called GPM J1839-10, which emits regular bursts of radio energy similar to a pulsar but with a much longer interval between pulses of 21 minutes. The nature and physics behind this behavior remain unknown, as it does not fit into any existing astronomical categories or explanations, making it a unique and enigmatic phenomenon that requires further study and observation. Ars Technica reports: GPM J1839-10 was discovered in a search of the galactic plane for transient objects -- something that's not there when you first look, but appears the next time you check. The typical explanation for a transient object is something like a supernova, where a major event gives something an immense boost in brightness. They're found at the radio end of the spectrum, fast radio bursts, but are also very brief and, so, fairly difficult to spot. In any case, GPM J1839-10 showed up in the search in a rather unusual way: It showed up as a transient item twice in the same night of observation. Rather than delivering a short burst of immense energy, such as a fast radio burst, GPM J1839-10 was much lower energy and spread out over a 30-second-long burst.

Follow-on observations showed that the object repeated pretty regularly, with a periodicity of about 1,320 seconds (more commonly known as 22 minutes). There's a window of about 400 seconds centered on that periodicity, and a burst can appear anywhere within the window and will last anywhere from 30 to 300 seconds. While active, the intensity of GPM J1839-10 can vary, with lots of sub-bursts within the main signal. Occasionally, a window will also go by without any bursts. A search through archival data showed that signals had been detected at the site as far back as 1988. So, whatever is producing this signal is not really a transient, in the sense that the phenomenon that's producing these bursts isn't a one-time-only event. The list of known objects that can produce this sort of behavior is short and consists of precisely zero items. [...]

So, given that every possible explanation is terrible, where do we go from here? The good news is that these objects will be so difficult to spot that it's possible there are a lot more out there that we've overlooked. The bad news is that they're still hard to spot. The length of the burst -- up to 300 seconds -- and the gap between bursts mean short-cadence observations will likely either see something there the whole time or miss it entirely. We'd really need to have hardware stare at a single area of space for a half-hour or more, and to have its staring divided up into multiple exposures, to be sure we catch it in both its on and off states. And that involves a major commitment of hardware. In the meantime, we can potentially narrow down the location of GPM J1839-10 to try to see if there's anything interesting in other wavelengths. Since this is located within the galactic plane, however, that's going to be challenging as well.

Artificial intelligence companies are exploring a new avenue to obtain the massive amounts of data needed to develop powerful generative models: creating the information from scratch. From a report: Microsoft, OpenAI and Cohere are among the groups testing the use of so-called synthetic data -- computer-generated information to train their AI systems known as large language models (LLMs) -- as they reach the limits of human-made data that can further improve the cutting-edge technology. The launch of Microsoft-backed OpenAI's ChatGPT last November has led to a flood of products rolled out publicly this year by companies including Google and Anthropic, which can produce plausible text, images or code in response to simple prompts.

The technology, known as generative AI, has driven a surge of investor and consumer interest, with the world's biggest technology companies including Google, Microsoft and Meta racing to dominate the space. Currently, LLMs that power chatbots such as OpenAI's ChatGPT and Google's Bard are trained primarily by scraping the internet. Data used to train these systems includes digitised books, news articles, blogs, search queries, Twitter and Reddit posts, YouTube videos and Flickr images, among other content. Humans are then used to provide feedback and fill gaps in the information in a process known as reinforcement learning by human feedback (RLHF). But as generative AI software becomes more sophisticated, even deep-pocketed AI companies are running out of easily accessible and high-quality data to train on. Meanwhile, they are under fire from regulators, artists and media organisations around the world over the volume and provenance of personal data consumed by the technology.

An anonymous reader shares a report: The four astronauts assigned to soar beyond the far side of the Moon on NASA's Artemis II mission settled into their seats inside a drab classroom last month at the Johnson Space Center in Houston. It was one in a series of noteworthy moments for the four-person crew since NASA revealed the names of the astronauts who will be the first people to fly around the Moon since 1972. There was the fanfare of the crew's unveiling to the public in April and an appearance on The Late Show with Stephen Colbert. There will, of course, be great anticipation as the astronauts close in on their launch date, currently projected for late 2024 or 2025. But many of the crew's days over the next 18 months will be spent in classrooms, on airplanes, or in simulators, with instructors dispensing knowledge they deem crucial for the success of the Artemis II mission. In the simulator, the training team will throw malfunctions and anomalies at the astronauts to test their ability to resolve a failure that -- if it happened in space -- could cut the mission short or, in a worst-case scenario, kill them.

"In order to do those things, what knowledge do we have to impart to them? What skills do we have to teach them?" said Jacki Mahaffey, NASA's leading training officer for the Artemis II mission. "Overall, our goal is we've got a little bit in the classroom, but the more that we can get the crew in front of the displays in the vehicle mockups and really kind of immersed in that environment, the sooner, the better. Commander Reid Wiseman and his crewmates -- pilot Victor Glover, mission specialist Christina Koch, and Canadian astronaut Jeremy Hansen -- were named to the Artemis II crew on April 3. Much of their time over the next two-and-a-half months was devoted to making a public relations tour, giving interviews, going to NASA centers around the country, visiting Capitol Hill, and meeting with Canadian Prime Minister Justin Trudeau. Mahaffey said they also got a pre-training pep talk from Charlie Duke, who walked on the Moon on the Apollo 16 mission in April 1972. NASA hasn't trained a crew to fly to the Moon since Apollo 17 at the end of 1972, the last time astronauts walked on the lunar surface.

At its annual Inspire conference, Microsoft announced a number of new AI features headed to Azure, perhaps the most notable of which is Vector Search. From a report: Available in preview through Azure Cognitive search, Vector Search uses machine learning to capture the meaning and context of unstructured data, including images and text, to make search faster. Vectorization, an increasingly popular technique in search, involves converting words or images into vectors, or series of numbers, that encode their meaning -- allowing them to be processed mathematically. Vectors enable machines to structure and make sense of data, enabling them to understand, for example, that words close together in "vector space" -- like "king" and "queen" -- are related and quickly surface them from a database of millions of words.

[...] Rounding out the AI unveilings at Inspire, Microsoft announced the public preview of Real-time Diarization, an AI-driven speech service that can identify which of several people are speaking in real time. The company also announced the general availability of Custom Neural Voice, which taps AI to closely reproduce an actor's voice or create an original synthetic voice. Previously, Custom Neural Voice was in limited access, meaning that customers had to apply and be approved by Microsoft in order to use it.

Wix, a longtime fixture of the web building space, is betting that today's customers don't particularly care to spend time customizing every aspect of their site's appearance. TechCrunch: The company's new AI Site Generator tool, announced today, will let Wix users describe their intent and generate a website complete with a homepage, inner pages and text and images -- as well as business-specific sections for events, bookings and more. Avishai Abrahami, Wix's co-founder and CEO, says that the goal was to provide customers with "real value" as they build their sites and grow their businesses. [...] AI Site Generator takes several prompts -- any descriptions of sites -- and uses a combination of in-house and third-party AI systems to create the envisioned site. In a chatbot-like interface, the tool asks a series of questions about the nature of the site and business, attempting to translate this into a custom web template. ChatGPT generates the text for the website while Wix's AI creates the site design and images.

"The James Webb Space Telescope has delivered yet another astounding discovery," reports CNN, "spying an active supermassive black hole deeper into the universe than has ever been recorded." The black hole lies within CEERS 1019 — an extremely old galaxy likely formed 570 million years after the big bang — making it more than 13 billion years old. And scientists were perplexed to find just how small the celestial object's central black hole measures. "This black hole clocks in at about 9 million solar masses," according to a NASA news release. A solar mass is a unit equivalent to the mass of the sun in our home solar system — which is about 333,000 times larger than the Earth. That's "far less than other black holes that also existed in the early universe and were detected by other telescopes," according to NASA. "Those behemoths typically contain more than 1 billion times the mass of the Sun — and they are easier to detect because they are much brighter."

The ability to bring such a dim, distant black hole into focus is a key feature of the Webb telescope, which uses highly sensitive instruments to detect otherwise invisible light...

The relative smallness of the black hole at CEER 1019's center is a mystery for scientists. It's not yet clear how such a small black hole formed in the early days of the universe, which was known to produce much larger gravity wells.
NASA's announcement emphasized the power of the James Webb Space Telescope. "Not only could the team untangle which emissions in the spectrum are from the black hole and which are from its host galaxy, they could also pinpoint how much gas the black hole is ingesting and determine its galaxy's star-formation rate."

The survey also recorded evidence of eleven new galaxies — which are still "churning out new stars," according to NASA. A member of the team says these new galaxies, "along with other distant galaxies we may identify in the future, might change our understanding of star formation and galaxy evolution throughout cosmic history."

Wikipedia notes that "Today, the Moon has no active volcanoes even though a significant amount of magma may persist under the lunar surface."

But this week the New York Times reports that "The rocks beneath an ancient volcano on the moon's far side remain surprisingly warm, scientists have revealed using data from orbiting Chinese spacecraft." The findings, which appeared last week in the journal Nature, help explain what happened long ago beneath an odd part of the moon. The study also highlights the scientific potential of data gathered by China's space program, and how researchers in the United States have to circumvent obstacles to use that data...

The Chinese orbiters both had microwave instruments, common on many Earth-orbiting weather satellites but rare on interplanetary spacecraft. The data from Chang'e-1 and Chang'e-2 thus provided a different view of the moon, measuring the flow of heat up to 15 feet below the surface — and proved ideal for investigating the oddity... At Compton-Belkovich, the heat flow was as high as 180 milliwatts per square meter, or about 20 times the average for the highlands of the moon's far side. That measure corresponds to a temperature of minus 10 degrees Fahrenheit about six feet below the surface, or about 90 degrees warmer than elsewhere. "This one stuck out, as it was just glowing hot compared to anywhere else on the moon," said Matthew Siegler, a scientist at the Planetary Science Institute, headquartered in Tucson, Ariz., and who led the research...

"Now we need the geologists to figure out how you can produce that kind of feature on the moon without water, without plate tectonics," Dr. Siegler said.
Universe Today believes this could help scientists better understand the moon's past. "What makes this finding unique is the source of the hotspot isn't active volcanism, such as molten lava, but from radioactive elements within the now-solidified rock that was once molten lava billions of years ago."

Thanks to Slashdot reader rolodexter for sharing the news.

An anonymous reader quotes a report from Phys.Org: Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called "impossible early galaxy problem." "Our newly-devised model stretches the galaxy formation time by a several billion years, making the universe 26.7 billion years old, and not 13.7 as previously estimated," says author Rajendra Gupta, adjunct professor of physics in the Faculty of Science at the University of Ottawa.

For years, astronomers and physicists have calculated the age of our universe by measuring the time elapsed since the Big Bang and by studying the oldest stars based on the redshift of light coming from distant galaxies. In 2021, thanks to new techniques and advances in technology, the age of our universe was thus estimated at 13.797 billion years using the Lambda-CDM concordance model. However, many scientists have been puzzled by the existence of stars like the Methuselah that appear to be older than the estimated age of our universe and by the discovery of early galaxies in an advanced state of evolution made possible by the James Webb Space Telescope. These galaxies, existing a mere 300 million years or so after the Big Bang, appear to have a level of maturity and mass typically associated with billions of years of cosmic evolution. Furthermore, they're surprisingly small in size, adding another layer of mystery to the equation.

Zwicky's tired light theory proposes that the redshift of light from distant galaxies is due to the gradual loss of energy by photons over vast cosmic distances. However, it was seen to conflict with observations. Yet Gupta found that "by allowing this theory to coexist with the expanding universe, it becomes possible to reinterpret the redshift as a hybrid phenomenon, rather than purely due to expansion." In addition to Zwicky's tired light theory, Gupta introduces the idea of evolving "coupling constants," as hypothesized by Paul Dirac. Coupling constants are fundamental physical constants that govern the interactions between particles. According to Dirac, these constants might have varied over time. By allowing them to evolve, the timeframe for the formation of early galaxies observed by the Webb telescope at high redshifts can be extended from a few hundred million years to several billion years. This provides a more feasible explanation for the advanced level of development and mass observed in these ancient galaxies. The research has been published in the journal Monthly Notices of the Royal Astronomical Society.

Congress will pour billions more dollars into the Space Launch System (SLS) rocket and its associated architecture, even as NASA science missions remain vulnerable to cuts. TechCrunch reports: Both the House and Senate Appropriations Committees recommend earmarking around $25 billion for NASA for the next fiscal year (FY 24), which is in line with the amount of funding the agency received this year (FY 23). However, both branches of Congress recommend increasing the portion of that funding that would go toward the Artemis program and its transportation cornerstones, SLS and the Orion crew capsule. Those programs would receive $7.9 billion per the House bill or $7.74 billion per the Senate bill, an increase of about $440 million from FY 2023 levels. Meanwhile, science missions are looking at cuts of around that same amount, with the House recommending a budget of $7.38 billion versus $7.79 billion in FY 2023.

Overall, NASA received $25.4 billion in funding for FY '23, with $2.6 billion earmarked toward SLS, $1.34 billion to Orion, and $1.48 to the Human Landing System contract programs. Science programs -- which include the Mars Sample Return mission and Earth science missions -- received $7.8 billion overall.

Researchers have discovered that samples of the Ryugu asteroid gathered in 2019 contain grains of stardust. NPR reports: The dust, which came from distant stars and drifted through space for millions or billions of years, could provide clues about how the solar system formed, according to Ann Nguyen, a cosmochemist at NASA's Johnson Space Center in Houston, Texas. Stars forged nearly all of the elements of the Universe. Many of the atoms that make up our bodies were themselves made inside of the core of a star somewhere else. That's because the high pressures and temperatures can fuse lightweight atomic nuclei into heavier elements. "The core is extremely hot, and then you go out in the atmosphere, it's cool enough so that gas can form and aggregate into tiny grains," Nguyen says.

Think of these little grains as cosmic dust motes. Sometimes the star that formed these grains would explode, blowing them across the galaxy like dandelion seeds. Other times they would drift away on their own -- traveling on the stellar wind into deep space. "Probably a lot of them do get destroyed," Nguyen says, "but some of them survive and they make it to our region of the universe where our solar system formed." The stardust swirled and clumped and eventually became part of the sun, and the planets, and even us. That idea led the astronomer Carl Sagan to famously remark that "We're made of star-stuff." [...]

Nguyen says the grains look different than the material from our own solar system, because different stars leave different nuclear signatures in the atoms. "It kind of lights up like a Christmas tree light," she says. "Their isotopic signatures are just so different than the material that formed in our solar system or got homogenized in the solar system." Nguyen says that the stardust grains provide some clues about the types of stars that contributed to our solar system. It also shows that exploding stars, or supernovae, probably contributed more of the dust than researchers had previously believed. But above all, she says, these tiny grains are a reminder of the way in which we fit into the vast cosmos. "It just shows us how rich our Universe is," she says. "These materials all played a part in our life here on Earth." The researchers published their findings in the journal Science Advances.

dcblogs writes: According to federal officials at a U.S. House hearing Thursday, the monumental federal buildings in Washington are largely empty, with some agencies using 25% or less of their headquarters' building capacity on average. The government owns some 511 million of square feet of office space, and capacity problems open the door to the possibility of conversions to housing or commercial uses. Commercial reuse has happened before. In 2013, the General Services Administration leased the Old Post Office Building at 1100 Pennsylvania Ave., to the Trump organization for a hotel.

"The taxpayer is quite literally paying to keep the lights on even when no one is home," said Rep. Scott Perry (R-Pa.), who chairs the infrastructure subcommittee meeting. The blame for the low utilization has several causes: a shift to hybrid work, out-of-date buildings that waste space, and designs before technology reduced the need for certain types of workers. The Republicans want federal workers to return to offices and reduce telecommuting to at least pre-pandemic levels. In February, the House passed H.R. 139, the Stopping Home Office Work's Unproductive Problems Act of 2023 -- or the Show Up Act -- requiring agencies to revert to 2019 pre-pandemic telework policies. A companion bill, S. 1565, is pending in the Senate. It has six Republican sponsors but no Democrats.

BlackRock's move into crypto fits into the asset management giant's broader mission of creating products that are easy to use and cheap for investors, CEO Larry Fink said Friday. From a report: "We believe we have a responsibility to democratize investing. We've done a great job, and the role of ETFs in the world is transforming investing. And we're only at the beginning of that," Fink said. BlackRock applied for a spot bitcoin ETF on June 15, which appeared to spur a rally in cryptocurrencies and a flurry of similar filings from other asset managers. The initial filing for the iShares Bitcoin Trust did not include a management fee.

[...] Fink had previously been critical of crypto, saying in 2017 that the popularity of digital currencies was do in large part to money laundering. However, interest from clients and the high cost of transactions motivated BlackRock to take a closer look at entering the space, Fink said. He also added that crypto can serve a diversification role in investor portfolios. "It has a differentiating value versus other asset classes, but more importantly, because it's so international it's going to transcend any one currency," Fink said.

The US Senate has slashed the budget for NASA's ambitious mission to return soil and rock samples from Mars' surface. From a report: NASA had asked for $949 million to support its Mars Sample Return mission, or MSR, in fiscal year 2024. In its proposed budget for the space agency, released Thursday, the Senate offered just $300 million and threatened to take that amount away. "The Committee has significant concerns about the technical challenges facing MSR and potential further impacts on confirmed missions, even before MSR has completed preliminary design review," stated the Commerce, Justice, Science, and Related Agencies subcommittee in its report on the budget.

The committee report, obtained by Ars, noted that Congress has spent $1.739 billion on the Mars Sample Return mission to date but that the public launch date -- currently 2028 -- is expected to slip, and cost overruns threaten other NASA science missions. Further, the report states that the $300 million allocated to the Mars mission will be rescinded if NASA cannot provide Congress with a guarantee that the mission's overall costs will not exceed $5.3 billion. In that case, most of the $300 million would be reallocated to the Artemis program to land humans on the Moon.

An Indian spacecraft blazed its way to the far side of the moon Friday in a follow-up mission to its failed effort nearly four years ago to land a rover softly on the lunar surface, the country's space agency said. From a report: Chandrayaan-3, the word for "moon craft" in Sanskrit, took off from a launch pad in Sriharikota in southern India with an orbiter, a lander and a rover, in a demonstration of India's emerging space technology. The spacecraft is set to embark on a journey lasting slightly over a month before landing on the moon's surface later in August. Applause and cheers swept through mission control at Satish Dhawan Space Center, where the Indian Space Research Organization's engineers and scientists celebrated as they monitored the launch of the spacecraft. Thousands of Indians cheered outside the mission control center and waved the national flag as they watched the spacecraft rise into the sky.

"Congratulations India. Chandrayaan-3 has started its journey towards the moon," ISRO Director Sreedhara Panicker Somanath said shortly after the launch. A successful landing would make India the fourth country -- after the United States, the Soviet Union, and China -- to achieve the feat. The six-wheeled lander and rover module of Chandrayaan-3 is configured with payloads that would provide data to the scientific community on the properties of lunar soil and rocks, including chemical and elemental compositions, said Dr. Jitendra Singh, junior minister for Science and Technology. India's previous attempt to land a robotic spacecraft near the moon's little-explored south pole ended in failure in 2019. It entered the lunar orbit but lost touch with its lander that crashed while making its final descent to deploy a rover to search for signs of water.

A private Chinese company launched into orbit on Wednesday the world's first methane-liquid oxygen rocket, beating U.S. rivals in sending what could become the next generation of launch vehicles into space. Reuters reports: The Zhuque-2 carrier rocket blasted off at 9 a.m. (0100 GMT) from the Jiuquan Satellite Launch Center in northwest China and completed its flight according to plan, state media reported. It was the second attempt by Beijing-based LandSpace, one of the earliest firms in China's commercial launch sector, to launch the Zhuque-2. A first attempt in December failed.

Wednesday's launch put China ahead of U.S. rivals, including Elon Musk's SpaceX and Jeff Bezos' Blue Origin, in the race to launch carrier vehicles fueled by methane, which is deemed less polluting, safer, cheaper and a suitable propellant in a reusable rocket. LandSpace also became the second private Chinese company to launch a liquid-propellent rocket. In April, Beijing Tianbing Technology successfully launched a kerosene-oxygen rocket, taking another step towards developing rockets that can be re-fueled and reused.

Chipotle has developed a robot that can cut the 50-minute process of making guacamole in half. "The fast-casual chain developed the collaborative robot, or cobot, in partnership with Vebu Labs, a California-based robotics startup," reports CNBC. "Chipotle also announced Wednesday that its $50 million venture arm, Cultivate Next, is investing in Vebu. Financial terms weren't disclosed." From the report: To prepare avocados using the Autocado, Chipotle employees load up the device with a full case of the ripe fruit. The Autocado can hold up to 25 pounds at one time. Then, the machine vertically orients the avocados, slices them in half and removes their cores and skin. A bowl at the bottom collects the fruit, which employees can then hand mash and mix with the rest of the guacamole ingredients.

Chipotle still wants employees to have a hand in making their guacamole. "There's no plan to test automated guac made in our restaurant," Curt Garner, Chipotle's chief technology officer, told CNBC. Employees don't have to monitor the Autocado while it prepares the avocados and can even use the top of the device as more counter space to prepare other ingredients. The prototype is "very close" to design for manufacture, according to Garner. Chipotle expects to test the Autocado in restaurants later this year.

Eventually, Vebu plans to add machine learning capabilities and sensors to the Autocado that will help it evaluate the quality of avocados. Preparing avocados for guacamole routinely ranks as one of employees' least favorite tasks, Garner said. It's also one of the most dangerous duties in Chipotle kitchens, sometimes resulting in knife injuries. On top of saving time and labor costs, the robot could also cut food waste. If the chain deploys the Autocado across its footprint of more than 3,200 locations, it could help save millions of dollars on avocados annually, the company said. Despite those savings, guacamole will probably still cost customers extra. "It's worth it," Garner said.

An anonymous reader quotes a report from Ars Technica: Two small spacecraft should have now been cruising through the Solar System on the way to study unexplored asteroids, but after several years of development and nearly $50 million in expenditures, NASA announced Tuesday the probes will remain locked inside a Lockheed Martin factory in Colorado. That's because the mission, called Janus, was supposed to launch last year as a piggyback payload on the same rocket with NASA's much larger Psyche spacecraft, which will fly to a 140-mile-wide (225-kilometer) metal-rich asteroid -- also named Psyche -- for more than two years of close-up observations. Problems with software testing on the Psyche spacecraft prompted NASA managers to delay the launch by more than a year. An independent review board set up to analyze the reasons for the Psyche launch delay identified issues with the spacecraft's software and weaknesses in the plan to test the software before Psyche's launch. Digging deeper, the review panel determined that NASA's Jet Propulsion Laboratory, which manages the Psyche mission, was encumbered by staffing and workforce problems exacerbated by the COVID-19 pandemic. Psyche is now back on track for liftoff in October on a SpaceX Falcon Heavy rocket, but Janus won't be aboard.

Janus was designed to fly to two binary asteroids -- consisting of two bodies near one another -- that orbit the Sun closer to Earth than the metallic asteroid Psyche. While the Psyche mission can still reach its asteroid destination and accomplish its science mission with a launch this year, the asteroids targeted by Janus will have changed positions in the Solar System by too much since last year. They are no longer accessible to the two Janus spacecraft without flying too far from the Sun for their solar arrays to generate sufficient power. When it became clear the two Janus target asteroids were no longer reachable, scientists on the Janus team and NASA management agreed last year to remove the twin spacecraft from the Psyche launch. Scientists considered other uses for the suitcase-size Janus spacecraft, which were already built and were weeks away from shipment to Florida to begin final launch preparations when NASA decided to delay the launch of Psyche.

One of the ideas to repurpose the Janus spacecraft was to send the probes to fly by asteroid Apophis, a space rock bigger than the Empire State Building that will encroach within 20,000 miles (32,000 kilometers) from our planet's surface in 2029. For a time soon after its discovery in 2004, scientists said there was a small chance Apophis could impact Earth in 2029 or later this century, but astronomers have now ruled out any risk of a collision for the next 100-plus years. In the end, Janus fell victim to the delay of the Psyche mission and tight budget constraints at NASA. The agency said Tuesday it has directed the Janus team to "prepare the spacecraft for long-term storage."
