Varda Space, Rocket Lab Nail First-of-Its-Kind Spacecraft Landing in Utah (techcrunch.com) 24

A spacecraft containing pharmaceutical drugs that were grown on orbit has finally returned to Earth today after more than eight months in space. From a report: Varda Space Industries' in-space manufacturing capsule, called Winnebago-1, landed in the Utah desert at around 4:40 p.m. EST. Inside the capsule are crystals of the drug ritonavir, which is used to treat HIV/AIDS. It marks a successful conclusion of Varda's first experimental mission to grow pharmaceuticals on orbit, as well as the first time a commercial company has landed a spacecraft on U.S. soil, ever. The capsule will now be sent back to Varda's facilities in Los Angeles for analysis, and the vials of ritonavir will be shipped to a research company called Improved Pharma for post-flight characterization, Varda said in a statement. The company will also be sharing all the data collected through the mission with the Air Force and NASA, per existing agreements with those agencies.

The first-of-its-kind reentry and landing is also a major win for Rocket Lab, which partnered with Varda on the mission. Rocket Lab hosted Varda's manufacturing capsule inside its Photon satellite bus; through the course of the mission, Photon provided power, communications, attitude control and other essential operations. At the mission's conclusion, the bus executed a series of maneuvers and de-orbit burns that put the miniature drug lab on the proper reentry trajectory. The final engine burn was executed shortly after 4 p.m. EST. Photon burned up in the atmosphere as planned while the capsule, protected by a heat shield and with the aid of a parachute, continued to land.

Firefly Software Snafu Sends Lockheed Satellite on Short-Lived Space Safari (theregister.com) 25

A software error on the part of Firefly Aerospace doomed Lockheed Martin's Electronic Steerable Antenna (ESA) demonstrator to a shorter-than-expected orbital life following a botched Alpha launch. From a report: According to Firefly's mission update, the error was in the Guidance, Navigation, and Control (GNC) software algorithm, preventing the system from sending the necessary pulse commands to the Reaction Control System (RCS) thrusters before the relight of the second stage. The result was that Lockheed's payload was left in the wrong orbit, and Firefly's engineers were left scratching their heads.

The launch on December 22, 2023 -- dubbed "Fly the Lightning" -- seemed to go well at first. It was the fourth for the Alpha, and after Firefly finally registered a successful launch a few months earlier in September, initial indications looked good. However, a burn of the second stage to circularize the orbit did not go to plan, and Lockheed's satellite was left in the wrong orbit, with little more than weeks remaining until it re-entered the atmosphere.

As it turned out, the Lockheed team completed their primary mission objectives. The payload was, after all, designed to demonstrate faster on-orbit sensor calibration. Just perhaps not quite that fast. Software issues aboard spacecraft are becoming depressingly commonplace. A recent example was the near disastrous first launch of Boeing's CST-100 Starliner, where iffy code could have led, in NASA parlance, to "spacecraft loss." In a recent interview with The Register, former Voyager scientist Garry Hunt questioned if the commercial spaceflight sector of today would take the same approach to quality as the boffins of the past.

YouTube Dominates TV Streaming In US, Per Nielsen's Latest Report (techcrunch.com) 22

In a new report today, Nielsen found that YouTube is once again the overall top streaming service in the U.S., with 8.6% of viewing on television screens. Netflix was a close second at 7.9% of TV usage. TechCrunch reports: In a blog post celebrating the achievement, the Google-owned streaming service announced that viewers now watch a daily average of over 1 billion hours of YouTube content on their televisions, which could indicate that there's a preference for user-generated videos among U.S. consumers rather than traditional TV shows. Sixty-one percent of Gen Z reported that they favor user-generated content over other content formats. [...]

Although YouTube may have precedence in the living room, TikTok continues to dominate on mobile devices. The short-form video app recently began testing the ability for TikTokers to upload 30-minute videos, which could step on YouTube's toes. TikTok also entered the spatial reality space, launching a native app on the Apple Vision Pro. Meanwhile, YouTube decided to not build a dedicated app for the device.

Astronomers Discover Universe's Brightest Object (theguardian.com) 43

The brightest known object in the universe, a quasar 500tn times brighter than our sun, was "hiding in plain sight," researchers say. From a report: Australian scientists spotted a quasar powered by the fastest growing black hole ever discovered. Its mass is about 17bn times that of our solar system's sun, and it devours the equivalent of a sun a day. The light from the celestial object travelled for more than 12bn years to reach Earth. Australian National University scientists first spotted it using a 2.3-metre telescope at the university's NSW Siding Spring Observatory in Coonabarabran. They then confirmed the find using the European Southern Observatory's (ESO's) Very Large Telescope, which has a primary mirror of 8 metres. The findings by the ANU researchers, in collaboration with the ESO, the University of Melbourne, and France's Sorbonne Universite have been published in Nature Astronomy.

To Combat Space Pollution, Japan Plans Launch of World's First Wooden Satellite (theguardian.com) 59

Japanese scientists plan to launch a satellite made of magnolia wood this summer on a U.S. rocket, reports the Observer.

Experiments carried out on the International Space Station showed magnolia wood was unusually stable and resistant to cracking — and "when it burns up as it re-enters the atmosphere after completing its mission, will produce only a fine spray of Âbiodegradable ash." The LignoSat probe has been built by researchers at Kyoto University and the logging company Sumitomo Forestry in order to test the idea of using biodegradable materials such as wood to see if they can act as environmentally friendly alternatives to the metals from which all satellites are currently constructed. "All the satellites which re-enter the Earth's atmosphere burn and create tiny alumina particles, which will float in the upper atmosphere for many years," Takao Doi a Japanese astronaut and aerospace engineer with Kyoto University, warned recently. "Eventually, it will affect the environment of the Earth."

To tackle the problem, Kyoto researchers set up a project to evaluate types of wood to determine how well they could withstand the rigours of space launch and lengthy flights in orbit round the Earth. The first tests were carried out in laboratories that recreated conditions in space, and wood samples were found to have suffered no measurable changes in mass or signs of decomposition or damage. "Wood's ability to withstand these conditions astounded us," said Koji Murata, head of the project.

After these tests, samples were sent to the ISS, where they were subjected to exposure trials for almost a year before being brought back to Earth. Again they showed little signs of damage, a phenomenon that Murata attributed to the fact that there is no oxygen in space which could cause wood to burn, and no living creatures to cause it to rot.

The article adds that if it performs well in space, "then the door could be opened for the use of wood as a construction material for more satellites."

Martians Wanted: NASA Opens Call for Simulated Yearlong Mars Mission (nasa.gov) 55

"Would you like to live on Mars?" NASA asked Friday on social media.

"You can help us move humanity toward that goal by participating in a simulated, year-long Mars surface mission at NASA's Johnson Space Center." NASA is seeking applicants to participate in its next simulated one-year Mars surface mission to help inform the agency's plans for human exploration of the Red Planet. The second of three planned ground-based missions called CHAPEA (Crew Health and Performance Exploration Analog) is scheduled to kick off in spring 2025.

Each CHAPEA mission involves a four-person volunteer crew living and working inside a 1,700-square-foot, 3D-printed habitat based at NASA's Johnson Space Center in Houston. The habitat, called the Mars Dune Alpha, simulates the challenges of a mission on Mars, including resource limitations, equipment failures, communication delays, and other environmental stressors. Crew tasks include simulated spacewalks, robotic operations, habitat maintenance, exercise, and crop growth.

NASA is looking for healthy, motivated U.S. citizens or permanent residents who are non-smokers, 30-55 years old, and proficient in English for effective communication between crewmates and mission control. Applicants should have a strong desire for unique, rewarding adventures and interest in contributing to NASA's work to prepare for the first human journey to Mars...

As NASA works to establish a long-term presence for scientific discovery and exploration on the Moon through the Artemis campaign, CHAPEA missions provide important scientific data to validate systems and develop solutions for future missions to the Red Planet. With the first CHAPEA crew more than halfway through their yearlong mission, NASA is using research gained through the simulated missions to help inform crew health and performance support during Mars expeditions.

You can see the simulated Mars habitat in this NASA video.

The deadline for applicants is Tuesday, April 2, according to NASA. "A master's degree in a STEM field such as engineering, mathematics, or biological, physical or computer science from an accredited institution with at least two years of professional STEM experience or a minimum of one thousand hours piloting an aircraft is required."

Scientists Discover Water On Surface of an Asteroid (space.com) 24

For the first time, scientists say they've detected water molecules on the surface of an asteroid. Space.com reports: Scientists studied four silicate-rich asteroids using data gathered by the now-retired Stratospheric Observatory for Infrared Astronomy (SOFIA), a telescope-outfitted plane operated by NASA and the German Aerospace Center. Observations by SOFIA's Faint Object InfraRed Camera (FORCAST) instrument showed that two of the asteroids -- named Iris and Massalia -- exhibit a specific wavelength of light that indicated the presence of water molecules at their surface, a new study reports.

While water molecules have previously been detected in asteroid samples returned to Earth, this is the first time that water molecules have been found on the surface of an asteroid in space. In a previous study, SOFIA found similar traces of water on the surface of the moon, in one of the largest craters in its southern hemisphere. [...]

Therefore, the findings at Iris and Massalia suggest that some silicate asteroids can conserve some of their water over the eons and may be more commonly found in the inner solar system than previously thought. In fact, asteroids are believed to be the primary source of Earth's water, providing the necessary elements for life as we know it. Understanding of the distribution of water through space will help researchers better assess where to search for other forms of potential life, both in our solar system and beyond.
The findings have been published in The Planetary Science Journal.

California Bill Wants To Scrap Environmental Reviews To Save Downtown San Francisco (sfchronicle.com) 177

An anonymous reader quotes a report from the San Francisco Chronicle: San Francisco's leaders have spent the past few years desperately trying to figure out how to deal with a glut of empty offices, shuttered retail and public safety concerns plaguing the city's once vibrant downtown. Now, a California lawmaker wants to try a sweeping plan to revive the city's core by exempting most new real estate projects from environmental review, potentially quickening development by months or even years. State Sen. Scott Wiener, D-San Francisco, introduced SB1227 on Friday as a proposal to exempt downtown projects from the California Environmental Quality Act, or CEQA, for a decade. The 1970 landmark law requires studies of a project's expected impact on air, water, noise and other areas, but Wiener said it has been abused to slow down or kill infill development near public transit.

"Downtown San Francisco matters to our city's future, and it's struggling -- to bring people back, we need to make big changes and have open minds," Wiener said in a statement. "That starts with remodeling, converting, or even replacing buildings that may have become outdated and that simply aren't going to succeed going forward." Eligible projects would include academic institutions, sports facilities, mixed-use projects including housing, biotech labs, offices, public works and even smaller changes such as modifying an existing building's exterior. The city's existing zoning and permit requirements would remain intact. "We're not taking away any local control," Wiener said in an interview with the Chronicle on Friday.

California Sen. Scott Wiener is proposing a bill that, he said, would make it easier for San Francisco's downtown area to recover from the pandemic. However, it's not clear how much of an impact the bill would have if it's eventually passed since other factors are at play. New construction has been nearly frozen in San Francisco since the pandemic, amid consistently high labor costs, elevated interest rates and weakening demand for both apartments and commercial space.Major developers have reiterated that they have no plans to start work on significant new projects any time soon. Last week, Kilroy Realty, which has approval for a massive 2.3 million-square-foot redevelopment ofSouth of Market's Flower Mart, said no groundbreakings are planned this year -- anywhere.

OSIRIS-REx's Final Haul: 121.6 Grams From Asteroid Bennu (universetoday.com) 17

According to NASA, the OSIRIS-REx mission has successfully collected 121.6 grams, or almost 4.3 ounces, of rock and dust from the asteroid Bennu. Universe Today reports: These samples have been a long time coming. The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, and Security-Regolith Explorer) was approved by NASA back in 2011 and launched in September 2016. It reached its target, the carbonaceous Apollo group asteroid 101955 Bennu, in December 2018. After spending months studying the asteroid and reconnoitring for a suitable sampling location, it selected one in December 2019. After two sampling rehearsals, the spacecraft gathered its sample on October 20th, 2020. In September 2023, the sample finally returned to Earth.

For OSIRIS-REx to be successful, it had to collect at least 60 grams of material. With a final total that is double that, it should open up more research opportunities and allow more of the material to be held untouched for future research. NASA says they will preserve 70% of the sample for the future, including for future generations. The next step is for the material to be put into containers and sent to researchers. More than 200 researchers around the world will receive samples. Many of the samples will find their way to scientists at NASA and institutions in the US, while others will go to researchers at institutions associated with the Canadian Space Agency, JAXA, and other partner nations. Canada will receive 4% of the sample, the first time that Canada's scientific community will have direct access to a returned asteroid sample.

Moon Company Intuitive Machines Begins First Mission After SpaceX Launch (cnbc.com) 7

Texas-based Intuitive Machines' inaugural moon mission began early Thursday morning, heading toward what could be the first U.S. lunar landing in more than 50 years. From a report: Intuitive Machines' Nova-C lander launched from Florida on SpaceX's Falcon 9 rocket, beginning the IM-1 mission. "It is a profoundly humbling moment for all of us at Intuitive Machines. The opportunity to return the United States to the moon for the first time since 1972 is a feat of engineering that demands a hunger to explore," Intuitive Machines vice president of space systems Trent Martin said during a press conference.

The IM-1 lander, named "Odysseus" after the mythological Greek hero, is carrying 12 government and commercial payloads -- six of which are for NASA under an $118 million contract. NASA leadership emphasized before the launch that "IM-1 is an Intuitive Machines' mission, it's not a NASA mission." But it marks the second mission under NASA's Commercial Lunar Payload Services (CLPS) initiative, which aims to deliver science projects and cargo to the moon with increasing regularity in support of the agency's Artemis crew program. The agency views CLPS missions as "a learning experience," NASA's deputy associate administrator for exploration in the science mission directorate, Joel Kearns, told press before the launch.

Google Joins Satellite Mission To Scan Globe for Methane Leaks (ft.com) 26

A new satellite mission to track planet-warming emissions of methane gas is finally set to launch, now aided with AI technology to help build a global map of oil and gas infrastructure and surveil it for leaks [Editor's note: the link may be paywalled; alternative source]. From a report: The MethaneSAT satellite was announced by the Environmental Defense Fund six years ago as a way to monitor releases of methane, an invisible gas that researchers estimate is responsible for almost a third of the emissions-induced increase in global temperatures since the start of the industrial era. The satellite is now scheduled to blast into space in March aboard a rocket operated by Elon Musk's SpaceX. On Wednesday, Google said it would provide the AI computing capabilities required to crunch vast amounts of data produced by the orbiting methane monitor.

MethaneSAT is the latest example of how satellites are used to detect methane emissions from oil and gas facilities, which is more than 80 times more potent than carbon dioxide at trapping heat in the atmosphere over a 20-year timescale. Experts say reducing methane emissions is one of the most powerful short-term actions needed to address global warming. The International Energy Agency this year found the global energy industry was responsible for 135mn tonnes of methane emissions in 2022, only slightly below record high levels of 2019. Existing satellites have detected more than 500 "super-emitting" events in 2022 from oil and gas operations, the IEA said, with a further 100 such events at coal mines, which can release methane during or after operations.

Y Combinator Seeks Startups in Robotics, Space and Defense (bloomberg.com) 11

Silicon Valley institution Y Combinator has released a new list of 20 types of startups it wants to join its accelerator program -- calling for applications in sectors like AI-powered robotics, space and defense technology. From a report: Y Combinator, YC for short, updates the list periodically, depending on what kinds of startups it sees gaining traction and where it thinks there's opportunity. This update, released in a blog post Wednesday, represents the biggest overhaul to its "requests for startups" since 2018. In a blog post Wednesday, YC Managing Director Dalton Caldwell described the requests as "ideas we'd want to see made real, in spaces that we believe will be important in the coming decades." The result is a window into the larger trends in the world of venture capital.

The first idea on YC's list is applying machine learning to robotics. "For decades, everyone has known that robots are the future, as any science fiction novel will show," YC partners wrote in the blog post. Now, advances around artificial intelligence are making the technology more useful, particularly in industrial settings. It listed autonomous tractors and infrastructure inspection robots as examples.

Amazon Prime Video Drops Dolby Vision, Atmos Unless You Pay Extra 90

Amazon Prime Video has cut Dolby Vision and Atmos support from their ad tier subscription. "That's on top of the ads that Amazon injected into the service on January 29th," reports The Verge. "Now, when you pay $2.99 a month to remove those ads, you can get Dolby Vision and Dolby Atmos back as well." The Verge reports: That's the word from 4KFilme, which discovered that their smart TVs from Sony, LG, and Samsung were now displaying content in HDR10 with Dolby Digital 5.1 as opposed to the higher fidelity options they'd enjoyed previously. Amazon spokesperson Katie Barker confirms to The Verge that it's a deliberate move: "Dolby Vision and Dolby Atmos capabilities are only available on the ad free option, on relevant titles."

While price hikes are no longer remotely unusual in the streaming video space, where Netflix now charges $22.99 a month for its 4K tier, it's a bit harder to compare Amazon's prices to Netflix. Prime Video is also available as an $8.99-per-month standalone subscription; if you subscribe that way and add $2.99 per month, it's more like a 28 percent price hike. If you prefer ads, Prime Video's $8.99-per-month is a dollar less than Disney Plus with ads at $9.99 per month, though Netflix currently offers its 1080p service with ads at $6.99 per month.

The Tech Company Super Bowl Ads of 2024 77

Technology made its mark on the Super Bowl ads this year. Microsoft purchased a long inspirational ad for Copilot, ending with the tagline "Your everyday AI companion." (Although another message made the opposite point. "With artificial intelligence, the future is in good hands," an announcer says ironically -- while the ad shows the minions from Despicable Me 4.)

Google's ad showed how its Pixel 8 smartphone helps people with vision problems take photos. T-Mobile touted its internet service.

And for some reason CrowdStrike's ad about its endpoint security software took place in the Old West...

VW ended an ad looking at its history with a shot of its new electric vehicle, the ID.Buzz minivan, while Kia had its own heart-tugging ad touting their electric EV9.

And Pfizer ran a minute-long ad showing the history of medical progress, culminating with a pointer to their new domain, LetsOutdoCancer.com.

Even NASA got into the action, releasing a video showing an astronaut catching a pass in zero gravity. ("Including its solar panels, the Space Station is the same size as a regulation football field.")

Nine US States Are Teaming Up To Accelerate the Adoption of Heat Pumps (wired.com) 209

An anonymous reader quotes a report from Wired: Death is coming for the old-school gas furnace -- and its killer is the humble heat pump. They're already outselling gas furnaces in the US, and now a coalition of states has signed an agreement to supercharge the gas-to-electric transition by making it as cheap and easy as possible for their residents to switch. Nine states have signed a memorandum of understanding that says that heat pumps should make up at least 65 percent of residential heating, air conditioning, and water-heating shipments by 2030. ("Shipments" here means systems manufactured, a proxy for how many are actually sold.) By 2040, these states -- California, Colorado, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, and Rhode Island -- are aiming for 90 percent of those shipments to be heat pumps.

"It's a really strong signal from states that they're committed to accelerating this transition to zero-emissions residential buildings," says Emily Levin, senior policy adviser at the Northeast States for Coordinated Air Use Management (NESCAUM), an association of air-quality agencies, which facilitated the agreement. The states will collaborate, for instance, in pursuing federal funding, developing standards for the rollout of heat pumps, and laying out an overarching plan "with priority actions to support widespread electrification of residential buildings."

Instead of burning planet-warming natural gas, a heat pump warms a building by transferring heat from the outdoor air into the interior space. Run it in the opposite direction, and it can cool the inside of a building -- a heat pump is both a heater and AC unit. Because the system is electric, it can run off a grid increasingly powered by renewables like wind and solar. Even if you have to run a heat pump with electricity from fossil-fuel power plants, it's much more efficient than a furnace, because it's moving heat instead of creating it. A heat pump can save an average American household over $550 a year, according to one estimate. They've gotten so efficient that even when it's freezing out, they can still extract warmth from the air to heat a home. You can even install a heat pump system that also warms your water.
"These states are aiming to further collaborate with those heat pump manufacturers by tracking sales and overall progress, sending a signal to the industry to ramp up production to meet the ensuing demand," reports Wired. "They'll also collaborate with each other on research and generally share information, working toward the best strategies for realizing the transition from gas to electric."

"Basically, they're pursuing a sort of standardization of the policies and regulations for getting more heat pumps built, bought, and installed, which other states outside of the coalition might eventually tap into."

With Miami Move, Jeff Bezos Proves Zip Codes Do Matter 170

Longtime Slashdot reader theodp writes: Our goal," Amazon founder Jeff Bezos explained in a Feb. 2021 Instagram post announcing the location of a second tuition-free @BezosAcademy preschool in Tacoma, WA, "is to unlock the potential in kids to become creative leaders, original thinkers, and lifelong learners -- regardless of their zip code."

Three years later, a new Amazon SEC filing reveals how much zip codes can matter, even to Bezos, the third richest person in the world. GeekWire reports: "A new Amazon [SEC] filing, detailing Jeff Bezos' plan to sell a slice of his stake in the company, sheds fresh light on his move from Seattle to Miami -- and his ability to avoid Washington state's capital gains tax [ironically, earmarked to be funneled into early-childhood education programs and school construction] in the process. The filing reveals that the Amazon founder and executive chairman adopted a trading plan Nov. 8 to sell up to 50 million Amazon shares during a period ending in January 2025. It would be the first time he has sold Amazon stock since 2021. The plan was adopted less than a week after Bezos announced on Instagram, on Nov. 2, that he was leaving his longtime home of Seattle for sunnier skies in Miami. In his Instagram post, Bezos said he wanted to be closer to his parents and Blue Origin space venture in Florida. He did not mention taxes."

"Given Bezos' recent move out of Washington -- where he founded and built Amazon into a global behemoth -- he will also be saving around $600 million in tax expense if he ends up selling the maximum of 50 million shares under the plan, based on the company's current stock price. That's around $600 million in what would have otherwise been tax revenue for his former home state, as The Center Square reported Monday. The capital gains tax, passed in 2021, imposes a 7% tax on any gains of more than $250,000 from the sale of stocks and bonds, with some exceptions. It was challenged in court but ultimately ruled constitutional by the state Supreme Court last year. The tax brought in nearly $900 million in its first year of collection. Revenue goes toward early education and childcare programs, as well as school construction projects."

It's of course no secret that Bezos is no fan of taxes -- he explored founding Amazon on an Indian reservation near San Francisco to avoid taxes, ponied up $100,000 to defeat a proposed WA state income tax aimed at improving WA state public education (joined in the fight by Microsoft and Steve Ballmer), characterized as unconstitutional attempts to make Amazon collect and pay sales taxes, and came under fire by ProPublica for paying no income tax in some years.

India To Launch Android Into Space To Test Crewed Launch Capability (theregister.com) 20

India's Space Research Organisation (ISRO) will send a humanoid robot astronaut into this space this year, then send it back alongside actual humans in 2025 on its long-delayed Gaganyaan orbital mission. From a report: According to the space agency, the robot-crewed Vyommitra Mission is scheduled for the third quarter of this year. The robot -- whose name translates to "Space Friend" in Sanskrit -- can monitor module parameters, issue alerts and execute life support operations. Vyommitra is also an excellent multitasker that can operate six panels while responding to queries and mimicking human functions. The humanoid speaks two languages: Hindi and English.

It's also been designated as female -- to the extent possible for a legless robot -- and sports coiffed hair, feminine facial features, and hands that look like they are wearing white gloves. It resembles a wax figurine or mannequin and The Register fancies it mostly manages to stay out of the Uncanny Valley -- the term applied to robots and digital depictions of humans that try to appear human but instead come off as creepy and/or unsettling.

SpaceX Launches NASA's PACE Satellite To Study Earth's Oceans, Air and Climate 7

NASA's nearly $1 billion PACE mission launched atop a SpaceX Falcon 9 rocket early this morning, successfully making it to polar orbit -- a first for NASA since 1960. "When it's up and running, PACE will make key observations of Earth's atmosphere and climate and allow scientists to assess the health of our oceans like never before," notes Space.com. From the report: PACE, by the way, is the first U.S. government mission to launch to a polar orbit from Florida since Nov. 30, 1960. On that day, a Thor Able Star rocket took off on such a trajectory but failed, raining debris down on Cuba, some of which apparently killed a cow. Rather than risk further incidents, the U.S. decided to conduct all of its subsequent polar launches from Vandenberg Air Force Base (now Vandenberg Space Force Base) in California -- until now. That said, PACE wasn't the first mission of any type to launch to polar orbit from Florida's Space Coast in six decades: SpaceX had completed 11 such commercial missions before sending PACE on its way.

PACE's handlers will now work to get the 10.5-foot-long (3.2 meters) spacecraft and its various subsystems up to speed. After this checkout period, the satellite can begin its science work. That work will be done by three instruments. One of them, a spectrometer called the Ocean Color Instrument (OCI), will map out the ocean's many hues in great detail and an unprecedented range, from near-infrared wavelengths all way to the ultraviolet. These colors are determined by the interaction of sunlight with particles in seawater, such as the chlorophyll produced by photosynthetic plankton, the base of the marine food web. So OCI will reveal quite a bit about the health and status of ocean ecosystems, according to PACE team members.

"PACE's unprecedented spectral coverage will provide the first-ever global measurements designed to identify phytoplankton community composition," NASA officials wrote in a PACE mission description. "This will significantly improve our ability to understand Earth's changing marine ecosystems, manage natural resources such as fisheries and identify harmful algal blooms." The satellite's other two instruments are polarimeters. They'll measure how the oscillation of light in a plane, known as its polarization, is affected by passage through the ocean, clouds and aerosols (particles suspended in the atmosphere). "Measuring polarization states of UV-to-shortwave light at various angles provides detailed information on the atmosphere and ocean, such as particle size and composition," NASA officials wrote in the mission description.

Meet 'Smaug-72B': The New King of Open-Source AI (venturebeat.com) 37

An anonymous reader shares a report: A new open-source language model has claimed the throne of the best in the world, according to the latest rankings from Hugging Face, one of the leading platforms for natural language processing (NLP) research and applications.

The model, called "Smaug-72B," was released publicly today by the startup Abacus AI, which helps enterprises solve difficult problems in the artificial intelligence and machine learning space. Smaug-72B is technically a fine-tuned version of "Qwen-72B," another powerful language model that was released just a few months ago by Qwen, a team of researchers at Alibaba Group.

What's most noteworthy about today's release is that Smaug-72B outperforms GPT-3.5 and Mistral Medium, two of the most advanced open-source large language models developed by OpenAI and Mistral, respectively, in several of the most popular benchmarks. Smaug-72B also surpasses Qwen-72B, the model from which it was derived, by a significant margin in many of these evaluations.
