NASA Officially Greenlights $3.35 Billion Mission To Saturn's Moon Titan (arstechnica.com) 52

NASA last week formally approved a $3.35 billion mission to explore Saturn's largest moon with a quadcopter drone. "Dragonfly is a spectacular science mission with broad community interest, and we are excited to take the next steps on this mission," said Nicky Fox, associate administrator of NASA's science mission directorate. "Exploring Titan will push the boundaries of what we can do with rotorcraft outside of Earth." The mission has a launch date of July 2028. Ars Technica reports: After reaching Titan, the eight-bladed rotorcraft lander will soar from place to place on Saturn's hazy moon, exploring environments rich in organic molecules, the building blocks of life. Dragonfly will be the first mobile robot explorer to land on any other planetary body besides the Moon and Mars, and only the second flying drone to explore another planet. NASA's Ingenuity helicopter on Mars was the first. Dragonfly will be more than 200 times as massive as Ingenuity and will operate six times farther from Earth.

Despite its distant position in the cold outer Solar System, Titan appears to be reminiscent of the ancient Earth. A shroud of orange haze envelops Saturn's largest moon, and Titan's surface is covered with sand dunes and methane lakes. Titan's frigid temperatures -- hovering near minus 290 degrees Fahrenheit (minus 179 degrees Celsius) -- mean water ice behaves like bedrock. NASA's Cassini spacecraft, which flew past Titan numerous times before its mission ended in 2017, discovered weather systems on the hazy moon. Observations from Cassini found evidence for hydrocarbon rains and winds that appear to generate waves in Titan's methane lakes. Clearly, Titan is an exotic world. Most of what scientists know about Titan comes from measurements collected by Cassini and the European Space Agency's Huygens probe, which Cassini released to land on Titan in 2005. Huygens returned the first pictures from Titan's surface, but it only transmitted data for 72 minutes.

Dragonfly will explore Titan for around three years, flying tens of kilometers about once per month to measure the prebiotic chemistry of Titan's surface, study its soupy atmosphere, and search for biosignatures that could be indications of life. The mission will visit more than 30 locations within Titan's equatorial region, according to a presentation by Elizabeth Turtle, Dragonfly's principal investigator at the Johns Hopkins University Applied Physics Laboratory. "The Dragonfly mission is an incredible opportunity to explore an ocean world in a way that we have never done before," Turtle said in a statement. "The team is dedicated and enthusiastic about accomplishing this unprecedented investigation of the complex carbon chemistry that exists on the surface of Titan and the innovative technology bringing this first-of-its-kind space mission to life."

Voyager 1 Resumes Sending Updates To Earth (nasa.gov) 53

quonset writes: Just over two weeks ago, NASA figured out why its Voyager 1 spacecraft stopped sending useful data. They suspected corrupted memory in its flight data system (FDS) was the culprit. Today, for the first time since November, Voyager 1 is sending useful data about its health and the status of its onboard systems back to NASA. How did NASA accomplish this feat of long distance repair? They broke up the code into smaller pieces and redistributed them throughout the memory.

From NASA: "... So they devised a plan to divide the affected code into sections and store those sections in different places in the FDS. To make this plan work, they also needed to adjust those code sections to ensure, for example, that they all still function as a whole. Any references to the location of that code in other parts of the FDS memory needed to be updated as well. The team started by singling out the code responsible for packaging the spacecraft's engineering data. They sent it to its new location in the FDS memory on April 18. A radio signal takes about 22 1/2 hours to reach Voyager 1, which is over 15 billion miles (24 billion kilometers) from Earth, and another 22 1/2 hours for a signal to come back to Earth. When the mission flight team heard back from the spacecraft on April 20, they saw that the modification worked: For the first time in five months, they have been able to check the health and status of the spacecraft. During the coming weeks, the team will relocate and adjust the other affected portions of the FDS software. These include the portions that will start returning science data.

Gaming Giant Embracer Group Is Splitting Into Three Companies (theverge.com) 13

Jess Weatherbed reports via The Verge: Swedish gaming conglomerate Embracer Group announced plans on Monday to split itself into three distinct games and entertainment companies: Asmodee Group, Coffee Stain & Friends, and Middle-earth Enterprises & Friends. These will be separate, publicly listed companies, according to Embracer, which says the move will allow "each entity to better focus on their respective core strategies and offer more differentiated and distinct equity stories for existing and new shareholders." [...]

The three new companies will be broken down as follows:

- Middle-earth Enterprises & Friends: This company, which will be renamed from Embracer Group, is described as a "creative powerhouse in AAA game development and publishing" that will retain ownership of the Dead Island, Killing Floor, Kingdom Come Deliverance, Tomb Raider, and The Lord of the Rings IPs.
- Asmodee Group: a new arm dedicated to publishing and distributing tabletop games. The existing catalog includes established titles like Ticket to Ride, 7 Wonders, Azul, CATAN, Dobble, and Exploding Kittens. Asmodee is also developing licensed tabletop games based on The Lord of the Rings, Marvel, Game of Thrones, and Star Wars franchises. Embracer anticipates the spinoff and share listings will take place "within 12 months."
- Coffee Stain & Friends: described as a "diverse gaming entity" that will focus on indie, mid-market, and free-to-play games. Properties sitting under this new company include Deep Rock Galactic, Goat Simulator, Satisfactory, Wreckfest, Teardown, and Valheim. The share listings are projected to become available in 2025.

Europe Baked in 'Extreme Heat Stress' Pushing Temperatures To Record Highs (theguardian.com) 103

Scorching weather has baked Europe in more days of "extreme heat stress" than its scientists have ever seen. The Guardian: Heat-trapping pollutants that clog the atmosphere helped push temperatures in Europe last year to the highest or second-highest levels ever recorded, according to the EU's Earth-watching service Copernicus and the World Meteorological Organization (WMO). Europeans are suffering with unprecedented heat during the day and are stressed by uncomfortable warmth at night. The death rate from hot weather has risen 30% in Europe in two decades, the joint State of the Climate report from the two organisations found.

"The cost of climate action may seem high," said WMO secretary-general Celeste Saulo, "but the cost of inaction is much higher." The report found that temperatures across Europe were above average for 11 months of 2023, including the warmest September since records began. The hot and dry weather fuelled large fires that ravaged villages and spewed smoke that choked far-off cities. The blazes that firefighters battled were particularly fierce in drought-stricken southern countries such as Portugal, Spain and Italy. Greece was hit by the largest wildfire recorded in the EU, which burned 96,000 hectares of land, according to the report. Heavy rain also led to deadly floods. Europe was about 7% wetter in 2023 than the average over the last three decades, the report found, and one-third of its river network crossed the "high" flood threshold. One-sixth hit "severe" levels.

Biden Marks Earth Day by Announcing $7 Billion in Solar Power Grants (time.com) 102

President Joe Biden travels to Triangle, Virginia, Monday to mark Earth Day, where he'll unveil $7 billion in grant funding for solar power under the Inflation Reduction Act and announce new steps to stand up his administration's American Climate Corps -- a program popular with youth climate groups. From a report: The announcements come days after the Biden administration made several significant conservation announcements, including barring oil drilling on nearly half of the national petroleum reserve in Alaska. Under the Environmental Protection Agency's Solar for All program, the administration will announce funding awards to states territories, tribal governments, municipalities and nonprofits "to develop long-lasting solar programs that are targeted towards the communities and people who need them most," EPA Deputy Administrator Janet McCabe told reporters. Per McCabe, the funding will enable nearly one million households in low-income and disadvantaged communities to benefit from solar power, saving more than $350 million in electric costs annually and more than $8 billion over the life of the program for overburdened households.

What Happened After Amazon Electrified Its Delivery Fleet? (yahoo.com) 198

Bloomberg looks at America's biggest operator of private electrical vehicle charging infrastructure: Amazon. "In a little more than two years, Amazon has installed more than 17,000 chargers at about 120 warehouses around the U.S." — and had Rivian build 13,500 custom electric delivery vans. Amazon has a long way to go. The Seattle-based company says its operations emitted about 71 million metric tons of carbon dioxide equivalent in 2022, up by almost 40% since Jeff Bezos's 2019 vow that his company would eventually stop contributing to the emissions warming the planet. Many of Amazon's emissions come from activities — air freight, ocean shipping, construction and electronics manufacturing, to name a few — that lack a clear, carbon-free alternative, today or any time soon. The company has not made much progress on decarbonization of long-haul trucking, whose emissions tend to be concentrated in industrial and outlying areas rather than the big cities that served as the backdrop for Amazon's electric delivery vehicle rollout...

Another lesson Amazon learned is one the company isn't keen to talk about: Going green can be expensive, at least initially. Based on the type of chargers Amazon deploys — almost entirely midtier chargers called Level 2 in the industry — the hardware likely cost between $50 million and $90 million, according to Bloomberg estimates based on cost estimates supplied by the National Renewable Energy Laboratory. Factoring in costs beyond the plugs and related hardware — like digging through a parking lot to lay wires or set up electrical panels and cabinets — could double that sum. Amazon declined to comment on how much it spent on its EV charging push.
In addition to the expense of the chargers, electric vehicle-fleet operators are typically on the hook for utility upgrades. When companies request the sort of increases to electrical capacity that Amazon has — the Maple Valley warehouse has three megawatts of power for its chargers — they tend to pay for them, making the utility whole for work done on behalf of a single customer. Amazon says it pays upgrade costs as determined by utilities, but that in some locations the upgrades fit within the standard service power companies will handle out of their own pocket.

The article also includes this quote from Kellen Schefter, transportation director at the Edison Electric Institute trade group (which worked with Amazon on its electricity needs). "Amazon's scale matters. If Amazon can show that it meets their climate goals while also meeting their package-delivery goals, we can show this all actually works."

Startup is Building the World's Largest Ocean-Based Carbon Plant - and It's Scalable (cnn.com) 54

An anonymous reader shared this report from CNN: On a slice of the ocean front in west Singapore, a startup is building a plant to turn carbon dioxide from air and seawater into the same material as seashells, in a process that will also produce "green" hydrogen — a much-hyped clean fuel.

The cluster of low-slung buildings starting to take shape in Tuas will become the "world's largest" ocean-based carbon dioxide removal plant when completed later this year, according to Equatic, the startup behind it that was spun out of the University of California at Los Angeles. The idea is that the plant will pull water from the ocean, zap it with an electric current and run air through it to produce a series of chemical reactions to trap and store carbon dioxide as minerals, which can be put back in the sea or used on land... The $20 million facility will be fully operational by the end of the year and able to remove 3,650 metric tons of carbon dioxide annually, said Edward Sanders, chief operating officer of Equatic, which has partnered with Singapore's National Water Agency to construct the plant. That amount is equivalent to taking roughly 870 average passenger cars off the road. The ambition is to scale up to 100,000 metric tons of CO2 removal a year by the end of 2026, and from there to millions of metric tons over the next few decades, Sanders told CNN. The plant can be replicated pretty much anywhere, he said, stacked up in modules "like lego blocks...."

The upfront costs are high but the company says it plans to make money by selling carbon credits to polluters to offset their pollution, as well as selling the hydrogen produced during the process. Equatic has already signed a deal with Boeing to sell it 2,100 metric tons of hydrogen, which it plans to use to create green fuel, and to fund the removal of 62,000 metric tons of CO2.

There's other projects around the world attempting ocean-based carbon renewal, CNN notes. "Other projects include sprinkling iron particles into the ocean to stimulate CO2-absorbing phytoplankton, sinking seaweed into the depths to lock up carbon and spraying particles into marine clouds to reflect away some of the sun's energy." But carbon-removal projects are controversial, criticized for being expensive, unproven at scale and a distraction from policies to cut fossil fuels. And when they involve the oceans — complex ecosystems already under huge strain from global warming — criticisms can get even louder. There are "big knowledge gaps" when it comes to ocean geoengineering generally, said Jean-Pierre Gatusso, an ocean scientist at the Sorbonne University in France. "I am very concerned with the fact that science lags behind the industry," he told CNN.

The Ingenuity Mars Helicopter Just Sent Its Last Message Home (livescience.com) 25

Two months ago the team behind NASA's Ingenuity Helicopter released a video reflecting on its historic explorations of Mars, flying 10.5 miles (17.0 kilometers) in 72 different flights over three years. It was the team's way of saying goodbye, according to NASA's video.

And this week, LiveScience reports, Ingenuity answered back: On April 16, Ingenuity beamed back its final signal to Earth, which included the remaining data it had stored in its memory bank and information about its final flight. Ingenuity mission scientists gathered in a control room at NASA's Jet Propulsion Laboratory (JPL) in California to celebrate and analyze the helicopter's final message, which was received via NASA's Deep Space Network, made up of ground stations located across the globe.

In addition to the remaining data files, Ingenuity sent the team a goodbye message including the names of all the people who worked on the mission. This special message had been sent to Perseverance the day before and relayed to Ingenuity to send home.

The helicopter, which still has power, will now spend the rest of its days collecting data from its final landing spot in Valinor Hills, named after a location in J.R.R. Tolkien's "The Lord of the Rings" books.

The chopper will wake up daily to test its equipment, collect a temperature reading and take a single photo of its surroundings. It will continue to do this until it loses power or fills up its remaining memory space, which could take 20 years. Such a long-term dataset could not only benefit future designs for Martian vehicles but also "provide a long-term perspective on Martian weather patterns and dust movement," researchers wrote in the statement. However, the data will be kept on board the helicopter and not beamed back to Earth, so it must be retrieved by future Martian vehicles or astronauts.

"Whenever humanity revisits Valinor Hills — either with a rover, a new aircraft, or future astronauts — Ingenuity will be waiting with her last gift of data," Teddy Tzanetos, an Ingenuity scientist at JPL, said in the statement.

Thursday NASA's Jet Propulsion Laboratory released another new video tracing the entire route of Ingenuity's expedition over the surface of Mars.

"Ingenuity's success could pave the way for more extensive aerial exploration of Mars down the road," adds Spacae.com: Mission team members are already working on designs for larger, more capable rotorcraft that could collect a variety of science data on the Red Planet, for example. And Mars isn't the only drone target: In 2028, NASA plans to launch Dragonfly, a $3.3 billion mission to Saturn's huge moon Titan, which hosts lakes, seas and rivers of liquid hydrocarbons on its frigid surface. The 1,000-pound (450 kg) Dragonfly will hop from spot to spot on Titan, characterizing the moon's various environments and assessing its habitability.

Could the Earth's Record Hot Streak Signal a New Climate Era? (msn.com) 170

South America's Amazon River has reached its lowest level since measurements began, according to the Washington Post, while temperatures "hovered above 110 degrees Fahrenheit" for nearly a week as April began in the capital of Mali. "Nights offered little relief, with temperatures often staying above 90 degrees..."

"An overtaxed electrical grid sputtered and shut down," they add, and "dehydration and heat stroke became epidemic... At the city's main hospital, doctors recorded a month's worth of deaths in just four days. Local cemeteries were overwhelmed." The historic heat wave that besieged Mali and other parts of West Africa this month — which scientists say would have been "virtually impossible" in a world without human-caused climate change — is just the latest manifestation of a sudden and worrying surge in global temperatures. Fueled by decades of uncontrolled fossil fuel burning and an El Niño climate pattern that emerged last June, the planet this year breached a feared warming threshold of 1.5 degrees Celsius above preindustrial levels. Nearly 19,000 weather stations have notched record high temperatures since January 1. Each of the last ten months has been the hottest of its kind.

The scale and intensity of this hot streak is extraordinary even considering the unprecedented amount of greenhouse gases in the atmosphere, researchers say. Scientists are still struggling to explain how the planet could have exceeded previous temperature records by as much as half a degree Celsius (0.9 degrees Fahrenheit) last fall. What happens in the next few months, said Gavin Schmidt, director of the NASA Goddard Institute for Space Studies, could indicate whether Earth's climate has undergone a fundamental shift — a quantum leap in warming that is confounding climate models and stoking ever more dangerous weather extremes.

But even if the world returns to a more predictable warming trajectory, it will only be a temporary reprieve from the conditions that humanity must soon confront, Schmidt said. "Global warming continues apace."

Will this summer's La Niña cool things off? More atmospheric research is underway, and "Schmidt says it's too soon to know how worried the world should be," according to the article. But he does raise this possibility. "What if the statistical connections that we are basing our predictions on are no longer valid?"

"It's niggling at the back of my brain that it could be that the past is no longer a guide to the future."

JWST Gets an IMAX Documentary: 'Deep Sky' (imax.com) 13

A large-screen IMAX documentary about the James Webb Space Telescope "has just opened in 300 theaters across North America," write an anonymous Slashdot reader, noting that it's playing for one week only. "And it gets a rave review in Forbes." Imagine venturing to the beginning of time and space, exploring cosmic landscapes so vast and beautiful that they've remained unseen by human eyes until now.

This is the promise of "Deep Sky," an extraordinary IMAX presentation that brings the universe's awe-inspiring mysteries closer than ever before. Directed by the Oscar®-nominated filmmaker Nathaniel Kahn and narrated by the equally acclaimed actress Michelle Williams, "Deep Sky" is a monumental journey through the cosmos, powered by the groundbreaking images captured by NASA's Webb Telescope... "Deep Sky" is more than a documentary about a space telescope; it's an immersive experience that invites audiences to see the universe as never before. Through the power of IMAX, viewers are transported across 13 billion years of cosmic history, to the very edges of the observable universe. Here, in stunning clarity, we witness the birth of stars, the formation of galaxies, and the eerie beauty of exoplanets — planets that orbit stars beyond our own Sun. These images, beamed back to Earth by JWST, reveal the universe's vast beauty on a scale that seems only the giant IMAX screen can begin to convey...

What makes "Deep Sky" particularly captivating is its ability to render the incomprehensible beauty and scale of the universe accessible. The IMAX® experience, known for its breathtaking visuals and sound, serves as the perfect medium to convey the majesty of the cosmos.

The review says the film celebrates the achieve of thousands of people working across decades, "aiming to answer some of humanity's oldest questions: Where did we come from? How did the universe begin? Are we alone in the vastness of space?"

The reviewer also spoke to JWST telescope scientist Matt Mountain — in another article applauding the film for "encapsulating the grandeur of space exploration on the IMAX canvas." In "Deep Sky," viewers are taken on a journey from the telescope's construction to its deployment and early operational phases. The documentary highlights the international collaboration and engineering marvels behind the JWST, featuring insights from key scientists and engineers who brought the telescope to life. The film aims to rekindle a sense of wonder about the universe and our place within it, emphasizing the human desire to explore and understand the cosmos.

Data Centers Are Turning to an Old Source of Power: Coal (yahoo.com) 57

The Washington Post reports on a new situation in Virginia: There, massive data centers with computers processing nearly 70 percent of global digital traffic are gobbling up electricity at a rate officials overseeing the power grid say is unsustainable unless two things happen: Several hundred miles of new transmission lines must be built, slicing through neighborhoods and farms in Virginia and three neighboring states. And antiquated coal-powered electricity plants that had been scheduled to go offline will need to keep running to fuel the increasing need for more power, undermining clean energy goals...

The $5.2 billion effort has fueled a backlash against data centers through the region, prompting officials in Virginia to begin studying the deeper impacts of an industry they've long cultivated for the hundreds of millions of dollars in tax revenue it brings to their communities. Critics say it will force residents near the [West Virginia] coal plants to continue living with toxic pollution, ironically to help a state — Virginia — that has fully embraced clean energy. And utility ratepayers in the affected areas will be forced to pay for the plan in the form of higher bills, those critics say. But PJM Interconnection, the regional grid operator, says the plan is necessary to maintain grid reliability amid a wave of fossil fuel plant closures in recent years, prompted by the nation's transition to cleaner power. Power lines will be built across four states in a $5.2 billion effort that, relying on coal plants that were meant to be shuttered, is designed to keep the electric grid from failing amid spiking energy demands. Cutting through farms and neighborhoods, the plan converges on Northern Virginia, where a growing data center industry will need enough extra energy to power 6 million homes by 2030...

There are nearly 300 data centers now in Virginia. With Amazon Web Services pursuing a $35 billion data center expansion in Virginia, rural portions of the state are the industry's newest target for development. The growth means big revenue for the localities that host the football-field-size buildings. Loudoun [County] collects $600 million in annual taxes on the computer equipment inside the buildings, making it easier to fund schools and other services. Prince William [County], the second-largest market, collects $100 million per year.

The article adds that one data center "can require 50 times the electricity of a typical office building, according to the U.S. Department of Energy. "Multiple-building data center complexes, which have become the norm, require as much as 14 to 20 times that amount."

One small power company even told the grid operator that data centers were already consuming 59% of the power they produce...

Ocean Spray Emits More PFAS Than Industrial Polluters, Study Finds (theguardian.com) 74

An anonymous reader quotes a report from The Guardian: Ocean waves crashing on the world's shores emit more PFAS into the air than the world's industrial polluters, new research has found, raising concerns about environmental contamination and human exposure along coastlines. The study measured levels of PFAS released from the bubbles that burst when waves crash, spraying aerosols into the air. It found sea spray levels were hundreds of thousands times higher than levels in the water. The contaminated spray likely affects groundwater, surface water, vegetation, and agricultural products near coastlines that are far from industrial sources of PFAS, said Ian Cousins, a Stockholm University researcher and the study's lead author. "There is evidence that the ocean can be an important source [of PFAS air emissions]," Cousins said. "It is definitely impacting the coastline."

The Stockholm researchers several years ago found that PFAS from ocean waves crashing are released into the air around shorelines, then can travel thousands of kilometers through the atmosphere before the chemicals return to land. The new research looked at levels in the sea spray as waves crash by testing ocean samples between Southampton in the UK and Chile. The chemicals' levels were higher in the northern hemisphere in general because it is more industrialized and there is not much mixing of water across the equator, Cousins said. It is unclear what the findings mean for human exposure. Inhalation of PFAS is an issue, but how much of the chemicals are breathed in, and air concentrations further from the waves, is still unknown.

NASA Veteran Behind Propellantless Propulsion Drive Announces Major Discovery (thedebrief.org) 258

Longtime Slashdot reader garyisabusyguy shares a report from The Debrief: Dr. Charles Buhler, a NASA engineer and the co-founder of Exodus Propulsion Technologies, has revealed that his company's propellantless propulsion drive, which appears to defy the known laws of physics, has produced enough thrust to counteract Earth's gravity. "The most important message to convey to the public is that a major discovery occurred," Buhler told The Debrief. "This discovery of a New Force is fundamental in that electric fields alone can generate a sustainable force onto an object and allow center-of-mass translation of said object without expelling mass." "There are rules that include conservation of energy, but if done correctly, one can generate forces unlike anything humankind has done before," Buhler added. "It will be this force that we will use to propel objects for the next 1,000 years until the next thing comes."

To document his team's discovery as well as the process behind their work, which Dr. Buhler cautions is in no way affiliated with NASA or the U.S. Government, the outwardly amiable researcher presented his findings at a recent Alternative Propulsion Energy Conference (APEC). Filled with both highly-credentialed career engineers and propulsion hobbyists, APEC is an organization The Debrief once referred to as the World's Most Exclusive (And Strange) Anti-Gravity Club. In conjunction with that presentation, "The Discovery of Propellantless Propulsion: The Direct Conversion of Electrical Energy into Physical Thrust," Dr. Buhler also sat down with APEC co-founder and moderator Tim Ventura to explain how his past in electrostatics, which is his primary area of expertise, ended up being a key component of his discovery of this new force. [...]

Up next, Buhler says his team is seeking funding to test their devices in space to better understand the force at work. "We're hoping to do some demos," said Buhler. "Some space demos. That's what we're trying to get some funding to do. I think that would be a great way to show off the technology." Besides proving once and for all that the force they are seeing is real, the accomplished engineer believes that such tests could encourage other scientists to search for an explanation of what exactly it is they are seeing. "I think it's a good opportunity for people to run these tests, look at them, watch them go in space, watch it move in space, and then say, "what does it imply? What are the implications?'" Until that time, Buhler says he believes his work proves that the force they are seeing is "fundamental" and that understanding it is the next logical step. "You can't deny this," he told Ventura. "There's not a lot to this. You're just charging up Teflon, copper tape, and foam, and you have this thrust."

So, while his team believes their experiments speak for themselves, the veteran scientist says he also believes it is the job of science to analyze and understand this discovery. If successful, he thinks it may even address some of the harder questions in science, including the nature of dark energy or even space/time itself. "It's easy to make these things," he said, "so it's a tool for the scientific community to use to try to explore those hard questions."
If there are companies or individuals interested in working with Exodus Propulsion Technologies, Buhler asks that they reach out via their LinkedIn page.

Northrop Grumman Working With SpaceX On US Spy Satellite System (reuters.com) 10

Longtime Slashdot reader SonicSpike shares a report from Reuters: Aerospace and defense company Northrop Grumman is working with SpaceX [...] on a classified spy satellite project already capturing high-resolution imagery of the Earth, according to people familiar with the program. The program, details of which were first reported by Reuters last month, is meant to enhance the U.S. government's ability to track military and intelligence targets from low-Earth orbits, providing high-resolution imagery of a kind that had traditionally been captured mostly by drones and reconnaissance aircraft. The inclusion of Northrop Grumman, which has not been previously reported, reflects a desire among government officials to avoid putting too much control of a highly-sensitive intelligence program in the hands of one contractor, four people familiar with the project told Reuters. 'It is in the government's interest to not be totally invested in one company run by one person,' one of the people said.

It's unclear whether other contractors are involved at present or could join the project as it develops. Northrop Grumman is providing sensors for some of the SpaceX satellites, the people familiar with the project told Reuters. Northrop Grumman, two of the people added, will test those satellites at its own facilities before they are launched. At least 50 of the SpaceX satellites are expected at Northrop Grumman facilities for procedures including testing and the installation of sensors in coming years, one of the people said. In March, Reuters reported that the National Reconnaissance Office, or NRO, in 2021 awarded a $1.8 billion contract to SpaceX for the classified project, a planned network of hundreds of satellites. So far, the people familiar with the project said, SpaceX has launched roughly a dozen prototypes and is already providing test imagery to the NRO, an intelligence agency that oversees development of U.S. spy satellites.

What Caused the Storm That Brought Dubai To a Standstill? 63

An anonymous reader shares a report: A storm hit the United Arab Emirates and Oman this week bringing record rainfall that flooded highways, inundated houses, grid-locked traffic and trapped people in their homes. [...] In the UAE, a record 254 millimetres (10 inches) of rainfall was recorded in Al Ain, a city bordering Oman. It was the largest ever in a 24-hour period since records started in 1949. Rainfall is rare in the UAE and elsewhere on the Arabian Peninsula, that is typically known for its dry desert climate. Summer air temperatures can soar above 50 degrees Celsius. But the UAE and Oman also lack drainage systems to cope with heavy rains and submerged roads are not uncommon during rainfall.

Following Tuesday's events, questions were raised whether cloud seeding, a process that the UAE frequently conducts, could have caused the heavy rains. Cloud seeding is a process in which chemicals are implanted into clouds to increase rainfall in an environment where water scarcity is a concern. The UAE, located in one of the hottest and driest regions on earth, has been leading the effort to seed clouds and increase precipitation. But the UAE's meteorology agency told Reuters there were no such operations before the storm. The huge rainfall was instead likely due to a normal weather system that was exacerbated by climate change, experts say. A low pressure system in the upper atmosphere, coupled with low pressure at the surface had acted like a pressure 'squeeze' on the air, according to Esraa Alnaqbi, a senior forecaster at the UAE government's National Centre of Meteorology. That squeeze, intensified by the contrast between warmer temperatures at ground level and colder temperatures higher up, created the conditions for the powerful thunderstorm, she said.

Average World Incomes To Drop By Nearly a Fifth By 2050, Study Says (theguardian.com) 123

Average incomes will fall by almost a fifth within the next 26 years as a result of the climate crisis, according to a study that predicts the costs of damage will be six times higher than the price of limiting global heating to 2C. From a report: Rising temperatures, heavier rainfall and more frequent and intense extreme weather are projected to cause $38tn of destruction each year by mid-century, according to the research, which is the most comprehensive analysis of its type ever undertaken, and whose findings are published in the journal Nature. The hefty toll -- which is far higher than previous estimates -- is already locked into the world economy over the coming decades as a result of the enormous emissions that have been pumped into the atmosphere through the burning of gas, oil, coal and trees.

This will inflict crippling losses on almost every country, with a disproportionately severe impact on those least responsible for climate disruption, further worsening inequality. The paper says the permanent average loss of income worldwide will be 19% by 2049. In the United States and Europe the reduction will be about 11%, while in Africa and south Asia it will be 22%, with some individual countries much higher than this. "It's devastating," said Leonie Wenz, a scientist at the Potsdam Institute for Climate Impact Research and one of the authors of the study. "I am used to my work not having a nice societal outcome, but I was surprised by how big the damages were. The inequality dimension was really shocking."

NASA Confirms That Debris From ISS Crashed Into Florida Home (nbcnews.com) 57

NASA has confirmed that a piece of metal that tore through a Florida home last month was space junk from the International Space Station. NBC News reports: The agency confirmed Monday that the 1.6-pound object was debris from a cargo pallet that had been intentionally released from the space station three years ago. The pallet, packed with aging batteries, was supposed to burn up harmlessly in Earth's atmosphere, but a piece survived -- the piece that smashed into a house in Naples, Florida, on March 8.

WINK News, a CBS News affiliate in southwestern Florida, first reported the incident. Naples resident Alejandro Otero told the outlet that the object crashed through the roof and two floors of his home. Otero was not home at the time, he told WINK News, but the metal object nearly hit his son, who was two rooms away. In a blog post about the incident, NASA said it had analyzed the object at the Kennedy Space Center in Florida and confirmed that it was part of the equipment used to mount the batteries on the cargo pallet.

The piece of space junk is roughly cylindrical in shape and is about 4-inches tall and 1.6-inches wide. NASA said agency staff studied the object's features and metal composition and matched it to the hardware that had been jettisoned from the space station in 2021. At that time, new lithium-ion batteries had recently been installed at the space station, so the old nickel hydrogen batteries were packed up for disposal. The space station's robotic arm released the 5,800-pound cargo pallet containing the batteries over the Pacific Ocean, as the outpost orbited 260 miles above the Earth's surface, according to NASA. NASA said it will perform a detailed investigation of the latest debris incident to determine how the object withstood the extreme trip through the atmosphere.

NASA Says New Plan Needed To Return Rocks From Mars; Current Mission Design Can't Deliver Before 2040 (bbc.com) 65

SonicSpike shares a report: The quest to return rock materials from Mars to Earth to see if they contain traces of past life is going to go through a major overhaul. The US space agency says the current mission design can't return the samples before 2040 on the existing funds and the more realistic $11bn needed to make it happen is not sustainable. Nasa is going to canvas for cheaper, faster "out of the box" ideas. It hopes to have a solution on the drawing board later in the year.

Returning rock samples from Mars is regarded as the single most important priority in planetary exploration, and has been for decades. Just as the Moon rocks brought home by Apollo astronauts revolutionised our understanding of early Solar System history, so materials from the Red Planet are likely to recast our thinking on the possibilities for life beyond Earth.

World's Coral Reefs Hit By a Fourth Mass Bleaching Event, NOAA Says (nbcnews.com) 57

The National Oceanic and Atmospheric Administration on Monday declared that Earth is in the midst of a "4th global coral bleaching event" that's been documented over the last 14 months in every major ocean basin, including off Florida in the United States, in Australia's Great Barrier Reef and in the South Pacific. "As the world's oceans continue to warm, coral bleaching is becoming more frequent and severe," said Derek Manzello, a coral reef ecologist who coordinates NOAA's Coral Reef Watch Program, in a news release. "When these events are sufficiently severe or prolonged, they can cause coral mortality, which hurts the people who depend on the coral reefs for their livelihoods." NBC News reports: Corals are critical ecosystems that support a vast array of fish and aquatic species, which help feed coastal communities and attract tourists. The economic value of reefs is estimated at $2.7 trillion per year, according to a 2020 report from the Global Coral Reef Monitoring Network. "They protect our coastline. They offer protection from storms and hurricanes. They have a great value for our economy and safety," [Ana Palacio, an assistant scientist at the Cooperative Institute for Marine and Atmospheric Studies, a research institute that is based at the University of Miami in partnership with NOAA] said.

In Florida, as sea surface temperatures spiked, bleaching started early in the season, experts said. "Normally, bleaching will be observed in the Northern Hemisphere around August and September. We started to observe bleaching in July last year," said Phanor Montoya-Maya, a marine biologist with the Coral Restoration Foundation, an organization that collects, restores and repopulates corals. Palacio said the region saw widespread mortality of elkhorn and staghorn corals, two species that have been the focus of restoration efforts. "In some locations, about 20% of those populations survived," Palacio said of restored corals. "We're concentrating our hope on why those corals survived and what they can tell us about resistance and how corals can be more resilient."

The last global coral bleaching event happened in 2014 and lasted until 2017. More than 56% of global reef areas saw temperatures that could cause bleaching during that time period. In an email on Monday, Manzello said that 54% of the world's coral reef areas had experienced bleaching-level heat stress in the past year and that the event was poised to become the worst bleaching event in history. "The percentage of reef areas experiencing bleaching-level heat stress has been increasing by roughly 1% per week," Manzello said. "It is likely that this event will surpass the previous peak."

Montoya-Maya said a bleaching alert is already in effect in Florida, even earlier than last year. He said the Coral Restoration Foundation was preparing for a busy summer responding to another bleaching event. The natural pattern of El Nino has begun to dissipate and NOAA's Climate Prediction Center estimates there is a 60% chance La Niaa develops this summer, which could help cool Atlantic waters and allow some corals to recover, at least temporarily.

Emissions Dropped 1.8% Every Year in California's Bay Area. Researchers Credit EVs (yahoo.com) 164

An anonymous reader shared this report from the Los Angeles Times: A network of air monitors installed in Northern California has provided scientists with some of the first measurable evidence quantifying how much electric vehicles are shrinking the carbon footprint of a large urban area. Researchers from UC Berkeley set up dozens of sensors across the Bay Area to monitor planet-warming carbon dioxide, the super-abundant greenhouse gas produced when fossil fuels are burned. Between 2018 and 2022, the region's carbon emissions fell by 1.8% each year, which the Berkeley researchers concluded was almost exclusively owed to drivers switching to electric vehicles, according to a study published in the journal Environmental Science & Technology.

In that time, Californians purchased about 719,500 zero-emission or plug-in hybrid vehicles, more than triple the amount compared to the previous five years, according to the California Department of Energy. The Bay Area also had a higher rate of electric vehicle adoption than the state as a whole.

While the findings confirm the state's transition to zero-emission vehicles is substantially lowering carbon emissions, it also reveals these reductions are still not on pace to meet the state's ambitious climate goals. Emissions need to be cut by around 3.7% annually, or nearly twice the rate observed by the monitors, according to Ronald Cohen, UC Berkeley professor of chemistry. Although cars and trucks are the state's largest source of carbon emissions, it underscores the need to deploy zero-emission technology inside homes and for the power grid.

"I think what we see right now is evidence of strong success in the transportation sector," Cohen said. "We're going to need equally strong success in home and commercial heating, and in the [industrial] sources. We don't yet see significant movement in those, but policy pushing on those is not as far ahead as policy on electric vehicles." Although cities only cover roughly 3% of global surface area, they produce about 70% of carbon emissions.
