Apple said Thursday it will spend $450 million with U.S. companies to enable its new emergency satellite texting feature. From a report: The majority of that money will go to Globalstar, Apple said, a Louisiana-based company that operates the satellites that make the feature possible. Apple isn't taking an equity stake in the company but it is committing to spend money for equipment and the service's operations. The funds will pay for satellites, as well as equipping ground stations with a new kind of antenna designed by Apple.

In September, Apple announced Emergency SOS with Satellite as a banner feature on new iPhone 14 models. If users are out of range of a cellular tower, such as in a remote area while camping, they can still connect to emergency services by pointing their phone into the sky and connecting to one of 24 Globalstar satellites in low Earth orbit. It will launch later this month through an iPhone software update. Thursday's announcement underscores the significant costs of operating the service. The feature is free for two years but Apple has left open the possibility of charging for it after that. The service is not entirely automated and it requires human-staffed call centers -- over 300 Globalstar employees will work on the service, Apple said.

U.S. Climate Envoy John Kerry on Wednesday unveiled a carbon offset plan that would allow corporations to fund renewable energy projects in developing countries that are struggling to transition away from fossil fuels. CNBC reports: The program, called the Energy Transition Accelerator, is in partnership with philanthropic groups like the Rockefeller Foundation and the Bezos Earth Fund and will be finalized over the coming year. Officials argue it could funnel billions of dollars from the private sector into the economies of developing countries working to shift to renewable power sources like wind or solar. The plan will create a new class of carbon offsets that represent investments in projects that help accelerate renewable energy projects or build climate change resilience in a developing country. Businesses can buy these offsets to balance out some portion of their CO2 emissions, and the money will go to these projects.

Chile and Nigeria are among the developing countries interested in the program, the State Department said, and Bank of America, Microsoft, PepsiCo and Standard Chartered Bank have "expressed interest in informing the ETA's development." [...] In order to buy these credits under the new program, companies must commit to achieve net-zero emissions by 2050 and report annually on emissions as well as progress toward the target, according to a draft of the plan. Fossil fuel companies are also not allowed to participate in the program. But several major environmental groups said they are not supporting the plan, arguing the proposal lacked details and could ultimately undermine efforts to reduce global emissions. "Carbon offsets are not an answer in a world already on fire, under water and facing mounting climate losses and damage," said Rachel Cleetus, policy director with the climate and energy program at the Union of Concerned Scientists. "A voluntary carbon credit program won't guarantee deep, real cuts in emissions -- it's tantamount to rearranging the deck chairs as the climate ship is going down."

Rocket designers with China's main launch vehicle institute have scrapped plans for an expendable super heavy-lift launcher in favor of a design featuring a reusable first stage. SpaceNews reports: A new model of a Long March 9 rocket featuring grid fins and no side boosters recently went on display at the ongoing Zhuhai Airshow in southern China, prompting speculation that the long-standing plan of an expendable rocket had been dropped. Liu Bing, director of the general design department at the China Academy of Launch Vehicle Technology (CALT), later confirmed the new direction in an interview with China Central Television Nov. 7.

The new, current plan for the rocket will be a three-stage, 108-meter-high, 10-meter-diameter and 4,180 metric ton rocket capable of delivering 150 tons to low Earth orbit (LEO), 50 tons to lunar transfer orbit (LTO), or 35 tons to Mars transfer orbit. The rocket is scheduled to be ready for test flight around 2030. Liu told CCTV however that the design has not been finalized and will likely see changes as the team selects the optimal pathway, while committing to the goal of constantly breaking through technological challenges and increasing its launching power.

Less than 1% of used clothing gets recycled into new garments, overwhelming countries like Ghana with discards. From a report: It's a disaster decades in the making, as clothing has become cheaper, plentiful and ever more disposable. Each year the fashion industry produces more than 100 billion apparel items, roughly 14 for every person on Earth and more than double the amount in 2000. Every day, tens of millions of garments are tossed out to make way for new, many into so-called recycling bins. Few are aware that old clothes are rarely recycled into new ones because the technology and infrastructure don't exist to do that at scale.

Instead, discarded garments enter a global secondhand supply chain that works to prolong their life, if only a little, by repurposing them as cleaning rags, stuffing for mattresses or insulation. But the rise of fast fashion -- and shoppers' preference for quantity over quality -- has led to a glut of low-value clothing that threatens to tank the economics of that trade and inordinately burdens developing countries. Meanwhile, the myth of circularity spreads, shielding companies and consumers from the inconvenient reality that the only way out of the global textile waste crisis is to buy less, buy better and wear longer. In other words, to end fast fashion.

[...] Globally, less than 1% of used clothing is actually remade into new garments, according to the Ellen MacArthur Foundation, a UK nonprofit. (In contrast, 9% of plastic and about half of paper gets recycled.) The retailers have vowed that what they collect will never go to landfill or waste. But the reality is far messier. Garments dropped at in-store take-back programs enter the multibillion-dollar global secondhand supply chain, joining a torrent of discards from charity bins, thrift stores and online resale platforms like ThredUp and Sellpy. The complex task of sorting through that waste stream falls to a largely invisible global industry of brokers and processors. Their business depends on exporting much of the clothing to developing countries for rewear. It's the most profitable option and, in theory, the most environmentally responsible, because reusing items consumes less resources than recycling them.

Almost but not quite in time for Halloween, astronomers announced on Friday that they had discovered the closest known black hole. It is a biggie, a shell of yawning emptiness 10 times as massive as the sun, orbiting as far from its own star as the Earth is from ours. From a report: Not to worry, however: This black hole is 1,600 light-years away, in the constellation Ophiuchus; the next nearest known black hole is about 3,000 light-years away in the constellation Monoceros. What sets this new black hole apart from the 20 or so others already identified in our Milky Way galaxy, besides its proximity, is that it isn't doing anything -- not drawing the nearby star to its doom, not gravitationally consuming everything nearby. Rather, the black hole is dormant, a silent killer waiting for the currents of space to feed it.

Kareem El-Badry, an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, has been searching for such hidden demons for four years. He found this black hole by scrutinizing data from the European Space Agency's GAIA spacecraft, which has been tracking with exquisite precision the positions, motions and other properties of millions of stars in the Milky Way. Dr. El-Badry and his team detected a star, virtually identical to our sun, that was jittering strangely, as if under the gravitational influence of an invisible companion.

To investigate further, the researchers commandeered the Gemini North telescope atop Mauna Kea in Hawaii, which could measure the speed and period of this wobble and thus determine the relative masses of the objects involved. The technique is identical to the process by which astronomers analyze the wobbles of stars to detect the presence of orbiting exoplanets -- except this time the quarry was far bigger. Their results and subsequent calculations were consistent with a black hole of 10 solar masses being circled by a star similar to our own. They named it Gaia BH1.

China launched the final module for its space station last Monday. But this also meant that a massive booster rocket re-entered the earth's atmosphere, notes the Washington Post — "for the fourth time in less than three years."

This one came down in the Pacific Ocean shortly after 6 a.m. Friday, and "there were no initial reports of damage or injuries. "But its return to Earth highlighted a tension among space faring nations over China's practice of letting its spent rockets tumble back to Earth after days in orbit." While the chances are low of any one person getting hit by the returning space debris, several of the tracks the rocket possibly could have taken passed over a large swath of the Earth's populated areas. NASA Administrator Bill Nelson has repeatedly condemned China for the practice. In a statement Friday morning, he said: "It is critical that all spacefaring nations are responsible and transparent in their space activities and follow established best practices, especially, for the uncontrolled reentry of a large rocket body debris — debris that could very well result in major damage or loss of life."

China is alone among space-faring nations in allowing the unplanned return of its boosters, instead of ditching them at sea, as most others do, or returning them to a soft landing, like Space X. "The technology exists to prevent this," said Ted Muelhaupt, a consultant in the chief engineer's office at the Aerospace Corporation, a nonprofit that drew possible tracks for the rocket's return. The rest of the world doesn't "deliberately launch things this big and intend them to fall wherever. We haven't done that for 50 years."

As of Wednesday, the [research nonprofit] Aerospace Corporation's calculations had the stage possibly landing over areas of land where 88 percent of the world's population lives. And so the possibility of casualties, Muelhaupt said, was between one in 230 to one in 1,000. That risk far exceeds the internationally recognized standard that says a reentering space object should not have greater than a one in 10,000 chance of causing injury.

The Chinese rocket stage is massive — weighing 22 metric tons and measuring as long as a pair of 53-foot semitrailers parked end to end, Muelhaupt said. He estimated that between 10 and 40 percent of the booster would survive reentry.

CNET reports on how research in Antarctica "could change astronomy forever": About 47 million light-years from where you're sitting, the center of a black-hole-laden galaxy named NGC 1068 is spitting out streams of enigmatic particles. These "neutrinos" are also known as the elusive "ghost particles" that haunt our universe but leave little trace of their existence.... Nestled into about 1 billion tons of ice, more than 2 kilometers (1.24 miles) beneath Antarctica, lies the IceCube Neutrino Observatory. A neutrino hunter, you might call it. When any neutrinos transfer their party to the frigid continent, IceCube stands ready.

In a paper published Friday in the journal Science, the international team behind this ambitious experiment confirmed it has found evidence of 79 "high-energy neutrino emissions" coming from around where NGC 1068 is located, opening the door for novel — and endlessly fascinating — types of physics. "Neutrino astronomy," scientists call it.

It'd be a branch of astronomy that can do what existing branches simply cannot.

Before today, physicists had only shown neutrinos coming from either the sun; our planet's atmosphere; a chemical mechanism called radioactive decay; supernovas; and — thanks to IceCube's first breakthrough in 2017 — a blazar, or voracious supermassive black hole pointed directly toward Earth. A void dubbed TXS 0506+056. With this newfound neutrino source, we're entering a new era of the particle's story. In fact, according to the research team, it's likely neutrinos stemming from NGC 1068 have up to millions, billions, maybe even trillions the amount of energy held by neutrinos rooted in the sun or supernovas. Those are jaw-dropping figures because, in general, such ghostly bits are so powerful, yet evasive, that every second, trillions upon trillions of neutrinos move right through your body. You just can't tell....

Not only is this moment massive because it gives us more proof of a strange particle that wasn't even announced to exist until 1956, but also because neutrinos are like keys to our universe's backstage. They hold the capacity to reveal phenomena and solve puzzles we're unable to address by any other means, which is the primary reason scientists are trying to develop neutrino astronomy in the first place.... Expected to be generated behind such opaque screens filtering our universe, these particles can carry cosmic information from behind those screens, zoom across great distances while interacting with essentially no other matter, and deliver pristine, untouched information to humanity about elusive corners of outer space.
The team says their data can provide information on two great unsolved mysteries in astronomy: why black holes emit sporadic blasts of light, and neutrinos' suspected role in the origin of cosmic rays.

The first crewed launch of Boeing's Starliner has been delayed again, this time being pushed back to April 2023 from an earlier planned launch date of February. The Register reports: The change came with little announcement from NASA, which tweeted out the new date as a scheduling update without any additional details. In an accompanying blog post, NASA said the change was being made to eliminate conflicts between "visiting spacecraft traffic at the space station," but the agency didn't elaborate much beyond that.

Starliner has been a drag on Boeing since the company unveiled the capsule in 2010. According to Boeing's Q3 2022 filing, Starliner has lost the company $883 million since 2019. That was the year Starliner made its first attempt at an uncrewed launch and docking with the International Space Station, which failed due to a pair of software errors that left it unable to dock and saw it returned to Earth early under less-than-ideal circumstances. Attempts at a second launch in 2021 also failed when 13 of the Calamity Capsule's propulsion system valves failed pre-flight checks. Starliner only made it to the ISS for the first time this past May, but even that launch wasn't without issues as two of the craft's 12 thrusters failed once in orbit.

An anonymous reader quotes a report from Space.com: The European continent is bearing the brunt of climate change, warming at a rate that is twice as fast as the global average, a new report by the World Meteorological Organization (WMO) found. The report analyzed 30 years' worth of data from 1991 onwards, revealing a disconcerting trend of speedy warming across Europe that is faster than the warming experienced by any other continent. Average temperatures in Europe were rising at a rate of 0.5 degrees Celsius (0.9 degrees Fahrenheit) per decade over the studied period, reaching an overall average of 2.2 degrees C (4 degrees F) above pre-industrial levels. That is way above the 1.5 degree C (2.7 degrees F) limit set by the international climatology community with the goal of minimizing devastating environmental effects of climate change.

The report, which was compiled in cooperation with the European Earth-observation program Copernicus, stated that Europeans are already feeling the pinch of this warming. According to estimates, the summer of 2022 was the driest in 500 years, with widespread water shortage and wildfires affecting even those nations that are usually accustomed to wetter summers. Alpine glaciers lost about one hundred feet (30 meters) in ice thickness from 1997 to 2021 as a result of the warming, according to the report. In 2021 alone, weather related disasters, mostly related to floods and storms, caused damages worth $50 billion across all European countries.

Scientists don't know exactly why Europe is warming so fast, Samantha Burgess, deputy director for climate change services at Copernicus told Space.com in a previous interview. The fast-paced warming may have something to do with the proximity of the Arctic, which is by far the world's fastest warming region. "We know that the Arctic is warming about three times faster than the global average rate," Burgess told Space.com last year. "It's already 3 degrees C [5.4 degrees F] warmer than in the pre-industrial times. It is quite complicated to unpick the scientific reasons behind why the warming is happening so much faster there." [...] The new WMO report states that regardless of emission reduction efforts, temperatures in all regions of Europe will continue to rise at a rate higher than the global average.

Scientists have discovered a huge "extragalactic structure" hidden behind the Milky Way in a mysterious area of the sky known as the "zone of avoidance" because it is obscured by our own galaxy's opaque bulge, according to a new preprint study. Motherboard reports: The discovery of the structure, which appears to be a large galaxy cluster, helps to fill in this shadowy part of our cosmic map, which may as well be labeled "here be space dragons" because it is so unclear what exists there. The star stuff that makes up our galaxy, the Milky Way, is distributed inside a thin plane that orbits around a central bulge that contains a supermassive black hole. The galactic plane and bulge are packed with stars, dust, and gas that block our view of whatever is on the other side. Though scientists have been able to use different wavelengths to peer through the zone of avoidance (ZoA), a region that obscures 10 to 20 percent of the sky, most of this region still remains out of view.

Now, a team led by Daniela Galdeano, an astronomer at the National University of San Juan in Argentina, report the discovery of "a new galaxy cluster, VVVGCl-B J181435-381432, behind the Milky Way bulge," which helps to complete "the picture of the large scale structure in this still little explored area of the sky," according to a study posted this week on the preprint server arxiv. [...] Galdeano and her colleagues were able to spot this cluster within the ZoA using the VVV Survey, a project that scans the Milky Way bulge at infrared wavelengths using the European Southern Observatory's Visible and Infrared Survey Telescope for Astronomy (VISTA) in Paranal, Chile. Whereas the galactic plane blocks out almost all visible light in the zone, longer wavelengths of light, including in the infrared band, are able to travel through the Milky Way's haze to reach telescopes on Earth.

To zoom in on the tantalizing region, the researchers used a near-infrared instrument called FLAMINGOS-2, which is on the Gemini South telescope in Chile, to identify measurements called "redshifts" that can be used to estimate the distance and velocities of its objects in space. The results exposed new details about five galaxies some three billion light years away, which the researchers think are part of a much bigger cluster. The team estimated that the cluster contains about 58 galaxies, but it will take more observations to be sure of its mass and contents.

As an added bonus, cleanup after rare earth extraction would be much easier. From a report: A variety of modern technologies, including permanent magnets that have been used in everything from earbuds to wind turbines, rely on rare earth elements. While the metals aren't actually especially rare, they don't occur at high concentrations in the Earth's crust. As such, extracting them is expensive and tends to produce a lot of environmental damage, meaning that most of the supply comes from a small number of countries (see the chart here), leaving the supply at risk of political fights. So the potential to get much more out of existing rare earth mines is obviously very appealing. And the method described in a paper released on Monday seems to offer it all: more metal per ore, much lower cost, and far less worry about mining waste.

Many of the best rare earth deposits occur in places where nature has concentrated the elements for us. These tend to be sediments formed from materials where the rare earth elements will react or interact with the sediment, coming out of solution and gradually building up the concentration in the ore. The usual method of extracting the elements from these ores essentially involves reversing that process. An ion-rich solution is pumped through the ore, and these ions displace the rare earths, allowing them to leach out of the ore. Typically, the solution used is ammonium sulfate. The production of ammonium sulfate has its own energy and materials costs, and it leaves the material behind in the ore, which may require an environmental cleanup afterward. And the process isn't very selective; lots of other, cheaper metals, like aluminum and calcium, also come out of the ore and need to be separated from the desired products.

A team of researchers has detected a trio of near-Earth asteroids in the inner solar system, one of which is the largest found since 2014 that poses a potential risk to the planet. The asteroids remained undetected until now because they occupy a region of the sky hidden by the Sun's glare. Gizmodo reports: Near-Earth Asteroids (NEAs) and Potentially Hazardous Asteroids (PHAs) are two types of near-Earth objects that space agencies like to keep track of. Despite the scary-sounding names, none of them pose any imminent threat to us. Currently, there are 1,454 NEAs that have a non-zero probability of impacting Earth in the next 100 years. You can find a complete list of NEOs at NASA's Center for Near Earth Object Studies.

The three near-Earth asteroids were found using the Dark Energy Camera in Chile. The camera took deep-field images close to Earth's horizon during twilight, to combat the Sun's glare and atmospheric distortions. The team's results are published in The Astronomical Journal. Two of the recently observed asteroids have orbits that safely skirt Earth, but one of the rocks -- a 0.93-mile-wide (1.5-kilometer) asteroid dubbed 2022 AP7 -- has an orbit that may eventually put it on a collision course with Earth. To be perfectly clear: The asteroid is not currently barreling toward Earth, but its path could bring it close enough one day that NASA will want to keep tabs on it.

The third and final module has arrived at China's Tiangong space station. Space.com reports: The Mengtian module launched to Earth orbit atop a Long March 5B heavy-lift rocket from Wenchang, south China, at 3:37 a.m. EDT (0737 GMT and 3:37 p.m Beijing time) on Monday (Oct. 31), according to the state-run outlet Xinhua News. Mengtian arrived at Tiangong as planned about 13 hours after liftoff, according to the China Manned Space Agency. The launch marked China's ninth space station-related mission since sending the Tianhe core module into orbit in April last year.

Mengtian, whose name means "Dreaming of the Heavens," is a 58.7-foot-long (17.9 meters) and roughly 48,500-pound (22 metric tons) spacecraft designed mainly to host an array of science racks and experiments. Equipment installed on board Mengtian will be used for experiments related to microgravity, fluid physics, materials science, combustion science, fundamental physics and more. The docking of Mengtian with Tiangong marks the end of the space station's assembly phase and the start of full operations, Chinese space officials have said. Mengtian's arrival allows China to realize a vision for a space station approved way back in 1992.

The Tiangong space station consists of Tianhe, Mengtian and a module called Wentian. The T-shaped Tiangong will host three astronauts for six months at a time, or six crew members for a brief time during crew handovers. Tiangong's first crew handover is expected before the end of the year when the ongoing Shenzhou 14 mission astronauts welcome aboard the new Shenzhou 15 crew, who will launch on a Long March 2F rocket from the Gobi Desert. Ahead of this, China will launch the Tianzhou 5 cargo mission to Tiangong in November to deliver supplies to support the new crew expedition. [...] The space station will also support a powerful survey space telescope named Xuntian that China plans to launch as soon as late 2023. The Hubble-class observatory will operate in a similar orbit to that of Tiangong, meaning it will be able to dock at the station for refueling, upgrades and repairs. Meanwhile, China's first astronaut, Yang Liwei, said earlier this year that Tiangong could be opened to tourism in the future.

NBC News reports: A global helium shortage has doctors worried about one of the natural gas's most essential, and perhaps unexpected, uses: MRIs.

Strange as it sounds, the lighter-than-air element that gives balloons their buoyancy also powers the vital medical diagnostic machines. An MRI can't function without some 2,000 liters of ultra-cold liquid helium keeping its magnets cool enough to work. But helium — a nonrenewable element found deep within the Earth's crust — is running low, leaving hospitals wondering how to plan for a future with a much scarcer supply.... [F]our of five major U.S. helium suppliers are rationing the element, said Phil Kornbluth, president of Kornbluth Helium Consulting. These suppliers are prioritizing the health care industry by reducing helium allotments to less essential customers.

Hospitals haven't canceled patients' MRIs or shut down machines yet. They have seen helium costs rise at an alarming rate, though — possibly up to 30%, guessed Phil Kornbluth, president of Kornbluth Helium Consulting. But without an end in sight for the helium shortage, the future of MRI remains uncertain.... The problem is that no other element is cold enough for the MRI. "There's no alternative," said Donna Craft, a regional construction manager for Premier Inc. who contracts with helium suppliers for some 4,000 hospitals. "Without helium, MRIs would have to shut down...."

GE and Siemens are both developing MRIs requiring less liquid helium. Siemens recently introduced one requiring just 0.7 liters, and, according to Panagiotelis, GE rolled out a machine that's "1.4 times more efficient than previous models." These technologies aren't widely available, though, and replacing the country's 12,000 MRI machines — each weighing up to 50,000 pounds — is anything but a quick fix. Meanwhile, hospitals keep installing additional conventional MRI machines to meet demand for diagnostic scans.
The article notes some scientists are already shutting down research projects that require helium.

"NASA's Earth Surface Mineral Dust Source Investigation (EMIT) mission is mapping the prevalence of key minerals in the planet's dust-producing deserts — information that will advance our understanding of airborne dust's effects on climate," NASA announced this week.

"But EMIT has demonstrated another crucial capability: detecting the presence of methane, a potent greenhouse gas." In the data EMIT has collected since being installed on the International Space Station in July, the science team has identified more than 50 "super-emitters" in Central Asia, the Middle East, and the Southwestern United States. Super-emitters are facilities, equipment, and other infrastructure, typically in the fossil-fuel, waste, or agriculture sectors, that emit methane at high rates. "Reining in methane emissions is key to limiting global warming. This exciting new development will not only help researchers better pinpoint where methane leaks are coming from, but also provide insight on how they can be addressed — quickly," said NASA Administrator Bill Nelson.

"The International Space Station and NASA's more than two dozen satellites and instruments in space have long been invaluable in determining changes to the Earth's climate. EMIT is proving to be a critical tool in our toolbox to measure this potent greenhouse gas — and stop it at the source...."

"These results are exceptional, and they demonstrate the value of pairing global-scale perspective with the resolution required to identify methane point sources, down to the facility scale," said David Thompson, EMIT's instrument scientist and a senior research scientist at NASA's Jet Propulsion Laboratory in Southern California, which manages the mission. "It's a unique capability that will raise the bar on efforts to attribute methane sources and mitigate emissions from human activities."

Relative to carbon dioxide, methane makes up a fraction of human-caused greenhouse-gas emissions, but it's estimated to be 80 times more effective, ton for ton, at trapping heat in the atmosphere in the 20 years after release. Moreover, where carbon dioxide lingers for centuries, methane persists for about a decade, meaning that if emissions are reduced, the atmosphere will respond in a similar timeframe, leading to slower near-term warming.... "Some of the plumes EMIT detected are among the largest ever seen — unlike anything that has ever been observed from space," said Andrew Thorpe, a research technologist at JPL leading the EMIT methane effort. "What we've found in a just a short time already exceeds our expectations."

For example, the instrument detected a plume about 2 miles (3.3 kilometers) long southeast of Carlsbad, New Mexico, in the Permian Basin. One of the largest oilfields in the world, the Permian spans parts of southeastern New Mexico and western Texas. In Turkmenistan, EMIT identified 12 plumes from oil and gas infrastructure east of the Caspian Sea port city of Hazar. Blowing to the west, some plumes stretch more than 20 miles (32 kilometers).... With wide, repeated coverage from its vantage point on the space station, EMIT will potentially find hundreds of super-emitters — some of them previously spotted through air-, space-, or ground-based measurement, and others that were unknown.

"As it continues to survey the planet, EMIT will observe places in which no one thought to look for greenhouse-gas emitters before, and it will find plumes that no one expects," said Robert Green, EMIT's principal investigator at JPL.

The mission of NASA's robotic lander InSight "is nearing an end as dust obscures its solar panels," reports CNN. "In a matter of weeks, the lander won't be able to send a beep to show it's OK anymore."

"Before it bids farewell, though, the spacecraft still has some surprises in store." When Mars rumbled beneath InSight's feet on December 24, NASA scientists thought it was just another marsquake. The magnitude 4 quake was actually caused by a space rock slamming into the Martian surface a couple thousand miles away. The meteoroid left quite a crater on the red planet, and it revealed glimmering chunks of ice in an entirely unexpected place — near the warm Martian equator.
The chunks of ice — the size of boulders — "were found buried closer to the warm Martian equator than any ice that has ever been detected on the planet," CNN explained earlier this week. The article also adds that ice below the surface of Mars "could be used for drinking water, rocket propellant and even growing crops and plants by future astronauts. And the fact that the ice was found so near the equator, the warmest region on Mars, might make it an ideal place to land crewed missions to the red planet." Interestingly, they note that scientists only realized it was a meteoroid strike (and not an earthquake) when "Before and after photos captured from above by the Mars Reconnaissance Orbiter, which has been circling Mars since 2006, spotted a new crater this past February." A crater that was 492 feet (150 meters) across and 70 feet (21 meters) deep... When scientists connected the dots from both missions, they realized it was one of the largest meteoroid strikes on Mars since NASA began studying the red planet.... The journal Science published two new studies describing the impact and its effects on Thursday....

"The image of the impact was unlike any I had seen before, with the massive crater, the exposed ice, and the dramatic blast zone preserved in the Martian dust," said Liliya Posiolova, orbital science operations lead for the orbiter at Malin Space Science Systems in San Diego, in a statement....

Researchers estimated the meteoroid, the name for a space rock before it hits the ground, was about 16 to 39 feet (5 to 12 meters). While this would have been small enough to burn up in Earth's atmosphere, the same can't be said for Mars, which has a thin atmosphere only 1% as dense as Earth's.... Some of the material blasted out of the crater landed as far as 23 miles (37 kilometers) away.

Teams at NASA also captured sound from the impact, so you can listen to what it sounds like when a space rock hits Mars. The images captured by the orbiter, along with seismic data recorded by InSight, make the impact one of the largest craters in our solar system ever observed as it was created.

Amazon is on a tight schedule to launch its internet satellites to orbit, so the company may have to turn to its competitor SpaceX for rides. Gizmodo reports: During a live interview with the Washington Post, Amazon senior vice president Dave Limp expressed the company's openness to use SpaceX's heavy lift rockets to deploy its Project Kuiper internet satellites. "We are open to talking to SpaceX, you'd be crazy not given their track record here," Limp said. However, Amazon is not interested in SpaceX's Falcon 9 rockets that are currently lofting the company's Starlink satellites. Amazon's internet satellites are larger than those being deployed by SpaceX, which explains why the company is eyeing SpaceX's Falcon Heavy rocket and its upcoming Starship rocket, the latter of which is still in development.

Limp's statement come as a surprise considering that Amazon signed deals earlier this year with Arianespace, Blue Origin, and United Launch Alliance to lift its satellites into orbit, while leaving out SpaceX from the mix. Both companies are aiming to bring high-speed internet to remote areas across the world by beaming down data signals from low Earth orbit. [...] Amazon is seemingly running out of options for rockets, while SpaceX has rockets-a-plenty, so a future deal between the industry rivals does make sense. A 2020 authorization order from the Federal Communications Commission stipulates that Amazon launch 50% of its 3,236 Project Kuiper satellites by 2026, and the remainder by 2029, or the company will lose its license.

An anonymous reader quotes a report from Phys.Org: Bumble bees play, according to new research led by Queen Mary University of London published in Animal Behavior. It is the first time that object play behavior has been shown in an insect, adding to mounting evidence that bees may experience positive "feelings." The team of researchers set up numerous experiments to test their hypothesis, which showed that bumble bees went out of their way to roll wooden balls repeatedly despite there being no apparent incentive for doing so. The study also found that younger bees rolled more balls than older bees, mirroring human behavior of young children and other juvenile mammals and birds being the most playful, and that male bees rolled them for longer than their female counterparts.

The study followed 45 bumble bees in an arena and gave them the options of walking through an unobstructed path to reach a feeding area or deviating from this path into the areas with wooden balls. Individual bees rolled balls between 1 and, impressively, 117 times over the experiment. The repeated behavior suggested that ball-rolling was rewarding. This was supported by a further experiment where another 42 bees were given access to two colored chambers, one always containing movable balls and one without any objects. When tested and given a choice between the two chambers, neither containing balls, bees showed a preference for the color of the chamber previously associated with the wooden balls. The set-up of the experiments removed any notion that the bees were moving the balls for any greater purpose other than play. Rolling balls did not contribute to survival strategies, such as gaining food, clearing clutter, or mating and was done under stress-free conditions. [...] The new research showed the bees rolling balls repeatedly without being trained and without receiving any food for doing so -- it was voluntary and spontaneous -- therefore akin to play behavior as seen in other animals. Study first-author, Samadi Galpayage, Ph.D. student at Queen Mary University of London says that "it is certainly mind-blowing, at times amusing, to watch bumble bees show something like play. They approach and manipulate these 'toys' again and again. It goes to show, once more, that despite their little size and tiny brains, they are more than small robotic beings."

"They may actually experience some kind of positive emotional states, even if rudimentary, like other larger fluffy, or not so fluffy, animals do. This sort of finding has implications to our understanding of sentience and welfare of insects and will, hopefully, encourage us to respect and protect life on Earth ever more."

One of Earth's toughest microbes could survive on Mars, lying dormant beneath the surface, for 280 million years, new research has shown. The findings increase the probability that microbial life could still exist on the Red Planet. Space.com reports: Deinococcus radiodurans, nicknamed "Conan the Bacterium," is one of the world's toughest microbes, capable of surviving in radiation strong enough to kill any other known life-form. Experiments have now shown that if Conan the Bacterium or a similar microbe existed on Mars, it could survive 33 feet (10 meters) beneath the surface, frozen and dried out, for 280 million years. In a study led by Michael Daly, who is a professor of pathology at Uniformed Services University of the Health Sciences in Maryland and a member of the National Academies' Committee on Planetary Protection, scientists tested half a dozen microbes and fungi -- all "extremophiles" able to live in environments where other organisms die -- to see how long they could survive in an environment that simulated the mid-latitudes of Mars. During the experiments, organisms faced temperatures as low as minus 80 degrees Fahrenheit (minus 63 degrees Celsius) and exposure to ultraviolet light, gamma rays and high-energy protons mimicking the constant bombardment of Mars by solar ultraviolet light and cosmic radiation sleeting down from space.

After the bacteria and fungi had been exposed to various radiation levels in the experiment, Daly's team measured how much manganese antioxidants had accumulated in the cells of the microbes. Manganese antioxidants form as a result of radiation exposure, and the more that form, the more radiation the microbes can resist. Conan the Bacterium was the clear winner. The researchers found that Conan the Bacterium could absorb as much as 28,000 times more radiation than what a human can survive. This measurement allowed Daly's team to estimate how long the microbe could survive at different depths on Mars. Previous experiments, in which Conan the Bacterium had been suspended in liquid water and subjected to radiation like that found on Mars, had indicated that the microbe could survive below the surface of Mars for 1.2 million years.

However, the new tests, in which the microbe was frozen and dried out to mimic the cold and dry conditions on Mars, suggested that Conan the Bacterium would be able to survive 280 million years on Mars if buried at a depth of 33 feet. This lifespan is reduced to 1.5 million years if buried just 4 inches (10 centimeters) below the surface, and just a few hours on the surface, which is bathed in ultraviolet light. [...] The research also determined why Conan the Bacterium is so resistant to radiation. The scientists found that chromosomes and plasmids, which carry genetic information, in the microbe's cells are linked together, which keeps these structures aligned and prevents irradiated cells from breaking down until they can be repaired. "Although Deinococcus radiodurans buried in the Martian subsurface could not survive dormant for the estimated 2 to 2.5 billion years since flowing water disappeared on Mars, such Martian environments are regularly altered and melted by meteorite impacts," he said in a statement. "We suggest that periodic melting could allow intermittent repopulation and dispersal."

The findings were detailed in the journal Astrobiology.

An anonymous reader shares a report: If you've been seeing mysterious Bladerunner-type ads popping up on your phone recently for Neom in Saudi Arabia and wondered what on earth you're looking at it's not surprising -- this futuristic desert development is eye-popping in its ambition. With a mammoth budget of $500 billion, Neom is a key element of Saudi's Vision 2030 plan originally launched back in 2016 as part of the kingdom's mission to diversify away from its oil-dependent economy. Excavation work started this month along the entire length of the project. The development has received its fair share of skepticism around feasibility, with a raft of articles in publications ranging from The Guardian to the Financial Times including commentary from architects who conclude the project is a pipe dream. Other critics note its carbon emissions among broader concerns.

Located on a coastal strip in Tabuk in the northwest of the country, there are three areas of Neom that have been officially announced -- primarily The Line, a linear city with Utopian vistas straight out of a Hollywood movie. Composed of two parallel skyscrapers that cut right through the desert for 170 kilometers from the coast to the mountains, The Line will be 200 meters wide and soar to a height of 500 meters (higher than most of the world's towers) -- and for an added surreal touch, will be encased on all sides with gigantic mirrors. The project is based on a new concept of "zero gravity urbanism," which is the idea of layering city functions vertically, while enabling inhabitants to move seamlessly in three directions (up, down, and across). When completed it could accommodate up to 9 million residents.

Cynicism toward the project is something Neom leaders acknowledge but strongly rebuff. "I want to be clear about this -- Neom is a complex, bold, and highly ambitious undertaking and is most certainly not an easy one to deliver," Antoni Vives, chief urban planning officer at Neom, told CNBC. "But we are making strong progress, and it's exciting to see the vision come to life." While construction of this "Oz of the Middle East" is only at the beginning stages, there's already a push to lure top international talent across industries such as tourism, technology, and entertainment to come and live and work. And there seems to be plenty of cash on the table to attract talent, with some reports suggesting Neom is paying top executives as much as $1.1 million a year.
