Amazon, stuck with too much warehouse capacity now that the surge in pandemic-era shopping has faded, is looking to sublet at least 10 million square feet of space and could vacate even more by ending leases with landlords, according to people familiar with the situation. From a report: The excess capacity includes warehouses in New York, New Jersey, Southern California and Atlanta, said the people, who requested anonymity because they're not authorized to speak about the deals. The surfeit of space could far exceed 10 million square feet, two of the people said, with one saying it could be triple that. Another person close to the deliberations said a final estimate on the square footage to be vacated hasn't been reached and that the figure remains in flux.

Amazon could try to negotiate lease terminations with existing landlords, including Prologis, an industrial real estate developer that counts the e-commerce giant as its biggest tenant, two of the people said. In a sign that Amazon is being careful not to cut too deeply should demand quickly rebound, the 10 million square feet the company is looking to sublet is roughly equivalent to about 12 of its largest fulfillment centers or about 5% of the square footage added during the pandemic. In another signal that Amazon is hedging its bets, some of the sublet terms would last just one or two years.

"NASA has released a huge new report that astronomers are calling Hubble's magnum opus," reports New Atlas.

"Analyzing 30 years of data from the famous space telescope, the new study makes the most precise measurement yet of how fast the universe is expanding." Astronomers have known for the better part of a century that the universe is expanding, thanks to the observation that galaxies are moving away from us — and the farther away they are, the faster they're traveling. The speed at which they're moving, relative to their distance from Earth, is a figure called the Hubble constant, and measuring this value was one of the primary missions of the space telescope of the same name.

To measure the Hubble constant, astronomers study distances to objects whose brightness is known well — that way, the dimmer it appears, the farther away it is. For relatively close objects within our galaxy or in nearby ones, this role is filled by Cepheids, a class of stars that pulse in a predictable pattern. For greater distances, astronomers use what are called Type Ia supernovae — cosmic explosions with a well-defined peak brightness....

For the new study, a team of scientists has now gathered and analyzed the most comprehensive catalog of these objects so far, to make the most precise measurement of the Hubble constant yet. This was done by studying 42 galaxies that contained both Cepheids and Type Ia supernovae, as imaged by the Hubble telescope over the last 30 years.

"This is what the Hubble Space Telescope was built to do, using the best techniques we know to do it," said Adam Riess, lead scientist of the team. "This is likely Hubble's magnum opus, because it would take another 30 years of Hubble's life to even double this sample size."
The article points out that these detailed real-world observations of the Hubble "constant" now show a small discrepancy, which suggests "new physics could be at work."

And it's the new James Webb Space Telescope that will now be studying these same phenomena at an even higher resolution.

NASA has released some surprisingly colorful visualization of black holes. Digital Trends explains their origins: We're coming to the end of Black Hole Week, NASA's celebration of the beastly cosmic monsters which suck in light, matter, and everything else that comes too close to them....

As part of the festivities, the media department at NASA's Goddard Space Flight Center has shared a selection of some of the best visualizations of black holes, so you can get an idea of what these mind-bending phenomena are like. The images, which are also available as desktop and mobile wallpapers should you wish to decorate your devices with black hole imagery, show simulations and visualizations created to try and picture what the weird effects of the extreme gravitational forces around a black hole would be.
NASA describes this as "translating the inherently digital data (in the form of ones and zeroes) captured by telescopes in space into images, [creating] visual representations of what would otherwise be invisible to us."

"But what about experiencing these data with other senses, like hearing?

"Sonification is the process that translates data into sound. Our new project brings parts of our Milky Way galaxy, and of the greater Universe beyond it, to listeners for the first time."


And elsewhere, CNN reports astronomers used the unique X-ray echoes released by rare "binary" black hole-star systems to identify six more such systems. (Only two were known previously.) And then converted their data into sound waves. The team tracked changes in the X-ray echoes, determined time lags during transition stages and traced commonalities in the evolution of each black hole outburst. The result sounds like something from a 1950s sci-fi film.

NASA and the German Aerospace Center are permanently shutting down the Stratospheric Observatory for Infrared Astronomy (SOFIA), a telescope on an aeroplane that has been scrutinized for years for its high cost and low scientific output. From a report: Since 2014, the observatory has made hundreds of flights above the water vapour in Earth's atmosphere to get an unobscured view of celestial objects and to gather data at infrared wavelengths. SOFIA has measured magnetic fields in galaxies1, spotted water on sunlit portions of the Moon2 and detected the first type of ion that formed in the Universe, helium hydride3. But it costs NASA around $85 million a year to operate, which is nearly as much as the operational expenses for the Hubble Space Telescope. On 28 April, NASA and the German Aerospace Center, the two partners in SOFIA, announced that they will close down the observatory by 30 September.

An anonymous reader quotes a report from TechCrunch: [R]esearchers are now finding vulnerabilities in newer hospital technologies that weren't as ubiquitous a decade ago. Enter autonomous hospital robots, the supposed-to-be-friendly self-controlled digital workhorses that can transport medications, bed linens, food, medications and laboratory specimens across a hospital campus. These robots, such as the ones built by robot maker Aethon, are equipped with the space to transport critical goods and security access to enter restricted parts of the hospital and ride elevators, all while cutting labor costs. But researchers at Cynerio, a cybersecurity startup focused on securing hospital and healthcare systems, discovered a set of five never-before-seen vulnerabilities in Aethon robots, which they say allowed malicious hackers to remotely hijack and control these autonomous robots -- and in some cases over the internet.

The five vulnerabilities, which Cynerio collectively call JekyllBot:5, aren't with the robots themselves but with the base servers that are used to communicate with and control the robots that traverse the hallways of the hospitals and hotels. The bugs range from allowing hackers to create new users with high-level access in order to then log in and remotely control the robots and access restricted areas, snoop on patients or guests using the robot's in-built cameras, or otherwise cause mayhem. Asher Brass, the lead researcher on the Aethon vulnerabilities, warned that the flaws required a "very low skill set for exploitation."

Cynerio said the base servers have a web interface that could be accessed from inside the hospital's network, allowing "guest" users to view real-time robot camera feeds and their upcoming schedules and tasks for the day without needing a password. But although the robots' functionality were protected by an "admin" account, the researchers said the vulnerabilities in the web interface could have allowed a hacker to interact with the robots without needing an admin password to log in. One of the five bugs, the researchers said, exposed robots to remote control using a joystick-style controller in the web interface, while exploiting another one of the bugs to interact with door locks, call and ride elevators, and open and close medication drawers. "The bugs were fixed in a batch of software and firmware updates released by Aethon, after Cynerio alerted the company to the issues," notes TechCrunch. "Aethon is said to have restricted internet-exposed servers to isolate the robots from potential remote attacks, and fixed other web-related vulnerabilities that affected the base station."

NBC News looks at the "thriving ecosystem" of space businesses "dramatically expanding access to the cosmos and fueling what is projected to grow into a trillion-dollar commercial space industry."

"Yet alongside the numerous benefits to society, increasing access to space and supporting an economy in orbit comes with its share of challenges, including how to balance a growing industry with the safe and sustainable use of outer space...." Speckled among the operational satellites in low-Earth orbit are thousands of tons of space debris, ranging from tiny flecks of paint to spent rocket parts to huge defunct spacecraft that have languished in orbital graveyards for decades. Adding more satellites to the mix not only increases the chances of a catastrophic on-orbit collision, but also pushes humanity closer to a perilous tipping point, beyond which certain parts of low-Earth orbit may become too cluttered and risky to operate in safely. "We're really on borrowed time before we have another big collision," said Charity Weeden, vice president of global space policy and government relations at Astroscale U.S., a private company that specializes in satellite servicing and orbital debris removal. "There are thousands of close calls every day in orbit...."

But placing all the blame on these megaconstellations is oversimplifying the problem, said Darren McKnight, a senior technical fellow at LeoLabs, a California-based aerospace company that operates networks of ground-based radars and tracking systems to monitor objects in low-Earth orbit and map their movements. For one, operational satellites make up only a small fraction of the total number of objects in low-Earth orbit that pose collision risks, he said. And unlike defunct spacecraft that have languished in orbit for decades, most newer satellites can be maneuvered out of harm's way, if necessary. It has also become standard practice for satellite operators to have an end-of-life plan to cut down on the accumulation of space junk. These strategies include purposefully commanding a spacecraft to "deorbit," or burn up harmlessly in Earth's atmosphere, or strand it in a higher, "graveyard" orbit away from the most congested sections around the planet.

Still, the risks are serious. And the amount of debris in space is expected to grow as launches continue. McKnight said "bad neighborhoods" have already emerged — areas in low-Earth orbit where big clouds of debris pose very real threats." There are certain places in Earth orbit where we are destined to have a major event within the next five to 10 years," he said. "We're looking at a 10 to 15 percent probability of a collision, which sounds unlikely, but by leaving these objects in orbit since the mid-'80s, we're rolling the dice a lot"

These risks were amplified by a series of recent anti-satellite missile tests — one conducted by China in 2007, one by India in 2019 and one carried out by Russia last year — and a separate accidental collision between two satellites in 2009. Each event is estimated to have produced thousands of pieces of debris larger than the size of a golf ball, and even smaller, harder-to-track objects, according to the Secure World Foundation, a nongovernmental organization that focuses on space policy...

Part of the problem is that while launches are subject to domestic regulations in individual countries, there is no international body to oversee what happens in orbit. Policies have yet to catch up with the industry's growth, and it's unclear if any binding global agreements can be achieved anytime soon.

"It's like we're building the plane as we're flying it," said Josef Koller, a systems director for the Center for Space Policy and Strategy at The Aerospace Corp.
The article also points out that companies like Astroscale are currently "developing technologies to actively remove objects from orbit."

An anonymous reader quotes a report from Motherboard: An object from another star system crashed into Earth in 2014, the United States Space Command (USSC) confirmed in a newly-released memo. The meteor ignited in a fireball in the skies near Papua New Guinea, the memo states, and scientists believe it possibly sprinkled interstellar debris into the South Pacific Ocean. The confirmation backs up the breakthrough discovery of the first interstellar meteor -- and, retroactively, the first known interstellar object of any kind to reach our solar system -- which was initially flagged by a pair of Harvard University researchers in a study posted on the preprint server arXiv in 2019.

Amir Siraj, a student pursuing astrophysics at Harvard who led the research, said the study has been awaiting peer review and publication for years, but has been hamstrung by the odd circumstances that arose from the sheer novelty of the find and roadblocks put up by the involvement of information classified by the U.S. government. The discovery of the meteor, which measured just a few feet wide, follows recent detections of two other interstellar objects in our solar system, known as 'Oumuamua and Comet Borisov, that were much larger and did not come into close contact with Earth.

"I get a kick out of just thinking about the fact that we have interstellar material that was delivered to Earth, and we know where it is," said Siraj, who is Director of Interstellar Object Studies at Harvard's Galileo Project, in a call. "One thing that I'm going to be checking -- and I'm already talking to people about -- is whether it is possible to search the ocean floor off the coast of Papua New Guinea and see if we can get any fragments." Siraj acknowledged that the odds of such a find are low, because any remnants of the exploded fireball probably landed in tiny amounts across a disparate region of the ocean, making it tricky to track them down. "It would be a big undertaking, but we're going to look at it in extreme depth because the possibility of getting the first piece of interstellar material is exciting enough to check this very thoroughly and talk to all the world experts on ocean expeditions to recover meteorites," he noted. "Siraj called the multi-year process a 'whole saga' as they navigated a bureaucratic labyrinth that wound its way though Los Alamos National Laboratory, NASA, and other governmental arms, before ultimately landing at the desk of Joel Mozer, Chief Scientist of Space Operations Command at the U.S. Space Force service component of USSC," adds Motherboard.

Mozer confirmed that the object indicated "an interstellar trajectory," which was first brought to Siraj's attention last week via a tweet from a NASA scientist. He's now "renewing the effort to get the original discovery published so that the scientific community can follow-up with more targeted research into the implications of the find," the report says.

Existence of volcanoes makes idea that dwarf planet is inert ball of ice look increasingly improbable. From a report: Strung out in the icy reaches of our solar system, two peaks that tower over the surface of the dwarf planet Pluto have perplexed planetary scientists for years. Some speculated it could be an ice volcano, spewing out not lava but vast quantities of icy slush -- yet no cauldron-like caldera could be seen. Now a full analysis of images and topographical data suggests it is not one ice volcano but a merger of many -- some up to 7,000 metres tall and about 10-150km across. Their discovery has reignited another debate: what could be keeping Pluto warm enough to support volcanic activity? Sitting at the southern edge of a vast heart-shaped ice sheet, these unusual surface features were initially spotted when Nasa's New Horizons spacecraft flew past in July 2015, providing the first close-up images of the icy former planet and its moons.

"We were instantly intrigued by this area because it was so different and striking-looking," said Dr Kelsi Singer, a New Horizons co-investigator and deputy project scientist at Southwest Research Institute in Boulder, Colorado. "There are these giant broad mounds, and then this hummocky-like, undulating texture superimposed on top; and even on top of that there's a smaller bouldery kind of texture." At the time, an ice volcano seemed like the least-weird explanation for these features -- there were no impact craters from asteroids or meteors nearby, suggesting these features had been erased by relatively recent geological events; and no evidence of plate tectonics -- a key contributor to mountain formation on Earth.

HP has purchased Poly, the company formerly known as Plantronics, for $3.3 billion. "HP Inc sees the future of its business as one supporting a workforce partially based at home and partially in the office, and appears to have bought office telecom giant Poly for that reason," reports The Register. From the report: Formerly known as Plantronics, Poly changed its name shortly after it acquired Polycom in 2018. HP didn't mention in its acquisition announcement whether or not it would keep the Poly brand separate, but it's still early: the deal is not expected to close until the end of the 2022 calendar year. HP described the $3.3 billion purchase ($40 per share) as a bid to refocus its portfolio on growth and take advantage of what it said is a massive growth opportunity due to the likely permanence of hybrid work.

Plantronics and Polycom have long had a considerable presence in the enterprise space, with Polycom's and Plantronics video conferencing hardware and headsets likely familiar to people in the world of work. Plantronics itself has a history reaching back to early airline headsets and the Apollo 11 mission: It's a Plantronics headset that relayed Neil Armstrong's "one small step" back to Earth. The value of peripherals like headsets hasn't declined in the years since, with HP saying the peripheral market is growing 9 percent annually and is worth $110 billion. Workforce solutions, like conference room telecom equipment, represents a $120 billion market segment that HP said is growing 8 percent yearly.

Three Russian cosmonauts arrived at the International Space Station last night for a six-month stay, writess the Times of London.

They were wearing flight suits "in the yellow and blue of the Ukrainian flag, in what appeared to be a daring statement against the war."

Space.com reports: Cosmonaut Oleg Artemyev, the Soyuz commander, was asked about the colors during a hatch-opening ceremony webcast by Russia's federal space agency Roscosmos. He responded (in Russian) that there was a surplus of yellow fabric in the warehouse, according to space exploration enthusiast Katya Pavlushchenko, who posted a Twitter thread about the exchange.

Not everybody's buying this answer, however. Some folks with knowledge of spaceflight procedures seem to think it could be a show of support for Ukraine, which Russia invaded on February 24.... There are other possible explanations for the flight suits as well. For example, multiple people on Twitter have pointed out that the colors are close to those of Bauman Moscow State Technical University, which Artemyev, Matveev and Korsakov all attended.

This is all just speculation; all we have to go on at the moment is Artemyev's cryptic response during the hatch-opening ceremony. Hopefully one of the cosmonauts will offer some more details in the not-too-distant future. None of the three newly arrived cosmonauts hails from Ukraine, by the way. Artemyev was born in present-day Latvia, Matveev is from St. Petersburg and Korsakov was born in what is now Kyrgyzstan.
Next month a SpaceX Dragon is expected to carry three millionaires to the Space Station for a week-long visit.

An anonymous reader quotes a report from Motherboard: Our universe is connected by a cosmic web made of giant threads of dark matter and gas that stretch across millions of light years and intersect at "nodes" populated by dense clusters of galaxies. This vast network shapes the distribution and evolution of galaxies in fundamental ways that scientists are trying to unravel with ever-sharper observations and advanced simulations. Now, a team led by Callum Donnan, a postgraduate student in astronomy at the University of Edinburgh, have identified a key correlation between the chemical makeup of galaxies and their location within the cosmic web. Using both real-life observations and computer simulations, the team found that "galaxies closer to nodes [display] higher chemical enrichment than those farther away," a discovery that reveals some of the mysterious dynamics that link the universe, according to a study published on Monday in Nature Astronomy.

To home in on this question, Donnan and his colleagues examined galaxies within about a billion light years of the Milky Way observed by the Sloan Digital Sky Survey in New Mexico, which covers a huge area of the sky. The team studied the elemental makeup of gasses in the interstellar spaces within these real-life galaxies, a property that is known as gas-phase metallicity. The results revealed that galaxies close to the nodes of the cosmic web were richer in "metals," which in astronomy refers to any element heavier than helium. A weaker correlation was also observed with proximity to the web's filaments, which are the threads that stretch across the universe and link nodes together. The team ran sophisticated cosmological simulations using the IllustrisTNG platform, which supported the observational findings. Significantly, the approach revealed that a galaxy's position in the cosmic web modulates its chemical content even when other factors, such as the density of a particular region in the universe, are taken into account.

Naturally, that raises the question of why galaxies located near nodes are enriched with more metals compared to those distributed along filaments or in empty "voids" within the cosmic web. Donnan's team isolated two major drivers of this relationship: The absorption of gas from outside of galaxies and the evolution of stars and dark matter inside of them. Galaxies feed on gasses that are strewn across space in the intergalactic medium, but those that are further from nodes consume much more of this outside material than those close to nodes. Since intergalactic gas is metal-poor, it dilutes the enriched gas of far-flung galaxies, lowering their overall gas-phase metallicities. Galaxies near nodes don't consume as much of this metal-poor material, which helps to keep them chemically enriched with higher concentrations of heavier elements. In addition, galaxies close to nodes seem to have matured earlier than those located at a distance. These galaxies had a head-start in birthing new stars and collecting dark matter, which is a mysterious substance that makes up most of the matter in the universe.

Right now an asteroid is zooming past earth "at a relatively close distance" reports Newsweek, "and the event can be viewed live." The asteroid, called 2022 ES3, will be traveling at 41,000 miles per hour when it comes between the moon and the Earth at around 2:18 p.m. ET on Sunday, March 13, according to NASA's Center for Near Earth Object Studies (CNEOS).

The space rock isn't expected to hit Earth. Instead, it will pass by at a distance of about 206,000 miles, which is about 87 percent of the distance between us and the moon.

The event provides a great viewing opportunity. An Italian astronomy organization called the Virtual Telescope Project, which often tracks asteroids and other space objects through the sky, is due to host a livestream of what it calls 2022 ES3's "very close, but safe, encounter with us" on its WebTV page starting at 18:30 UTC on March 13th.

Astronomers don't consider 2022 ES3 to be potentially hazardous, probably due to its size. The asteroid is predicted to be somewhere between 33 and 72 feet in diameter — about as wide as the length of a bowling lane.... [S]cientists track more than 28,000 near-Earth asteroids as they travel through the solar system. Around 900 of these are more than one kilometer, or 3,280 feet, in size.

A leading American Internet service provider, Cogent Communications, said it was severing relations with Russian customers on Friday, a move that gives Ukrainian officials another victory in their campaign to isolate Russia online. The Washington Post reports: Cogent chief executive Dave Schaeffer said the company did not want to keep ordinary Russians off the Internet but did want to prevent the Russian government from using Cogent's networks to launch cyberattacks or deliver propaganda targeting Ukraine at a time of war. "Our goal is not to hurt anyone. It's just to not empower the Russian government to have another tool in their war chest," Schaeffer said in an interview with The Washington Post.

Cogent, based in Washington, D.C., is one of the world's largest providers of what's known as Internet backbone -- roughly comparable to the interstate highway system, providing the primary conduit for data flows that local companies then route to individual domains. Schaeffer said Cogent's networks carry about one-quarter of the world's Internet traffic. Cogent has several dozen customers in Russia, with many of them, such as state-owned telecommunications giant Rostelecom, being close to the government.

Russia, like most nations, is connected to the world by several backbone providers, but Cogent is among its largest. The company began terminating its Russian companies at noon Friday but was doing so gradually. Some customers asked for a delay of up to several days while they found other Internet sources, Schaeffer said, and the company is trying to accommodate those requests. "We're pretty confident that we're not interfering with anyone's ability to get some information," he said, though he acknowledged the likelihood of slowdowns and other disruptions with Russia. "In light of the unwarranted and unprovoked invasion of Ukraine, Cogent is terminating all of your services effective at 5 p.m. GMT on March 4, 2022," wrote Cogent in a letter to one of their Russian customers. "The economic sanctions put in place as a result of the invasion and the increasingly uncertain security situation make it impossible for Cogent to continue to provide you with service. All Cogent-provided ports and IP address space will be reclaimed as of the termination date."

Scientific American reports: To hurtle around a corner along the fastest "racing line" without losing control, race car drivers must brake, steer and accelerate in precisely timed sequences. The process depends on the limits of friction, and they are governed by known physical laws — which means self-driving cars can learn to complete a lap at the fastest possible speed (as some have already done). But this becomes a much knottier problem when the automated driver has to share space with other cars. Now scientists have unraveled the challenge virtually by training an artificial intelligence program to outpace human competitors at the ultrarealistic racing game Gran Turismo Sport. The findings could point self-driving car researchers toward new ways to make this technology function in the real world.

Artificial intelligence has already conquered human players within certain video games, such as Starcraft II and Dota 2. But Gran Turismo differs from other games in significant ways, says Peter Wurman, director of Sony AI America and co-author of the new study, which was published this week in Nature. "In most games, the environment defines the rules and protects the users from each other," he explains. "But in racing, the cars are very close to each other, and there's a very refined sense of etiquette that has to be learned and deployed by the [AI] agents. In order to win, they have to be respectful of their opponents, but they also have to preserve their own driving lines and make sure that they don't just give way."

To teach their program the ropes, the Sony AI researchers used a technique called deep reinforcement learning. They rewarded the AI for certain behaviors, such as staying on the track, remaining in control of the vehicle and respecting racing etiquette. Then they set the program loose to try different ways of racing that would enable it to achieve those goals. The Sony AI team trained multiple different versions of its AI, dubbed Gran Turismo Sophy (GT Sophy), each specialized in driving one particular type of car on one particular track. Then the researchers pitted the program against human Gran Turismo champions. In the first test, conducted last July, humans achieved the highest overall team score. On the second run in October 2021, the AI broke through. It beat its human foes both individually and as a team, achieving the fastest lap times....

"The lines the AI was using were so tricky, I could probably do them once. But it was so, so difficult — I would never attempt it in a race," says Emily Jones, who was a world finalist at the FIA-Certified Gran Turismo Championships 2020 and later raced against GT Sophy.... "Racing, like a lot of sports, is all about getting as close to the perfect lap as possible, but you can never actually get there," Jones says. "With Sophy, it was crazy to see something that was the perfect lap. There was no way to go any faster."
The article notes that Sony AI is now working with Gran Turismo's developer (the Sony Interactive Entertainment subsidiary Polyphony Digital) to potentially incorporate a version of their AI into a future update of the game. "To do this, the researchers would need to tweak the AI's performance so it can be a challenging opponent but not invincible..."

Our nearest neighboring star, Proxima Centauri, may be harboring an extensive solar system, as scientists believe they've found a third planet orbiting it. From a report: It's a find that re-emphasizes just how commonplace planets outside our Solar System may be -- and it provides us with a third possible world nearby to study and potentially explore. Located a little more than 4 light-years from Earth, Proxima Centauri has long captured the imagination of scientists and sci-fi enthusiasts as a prime place to visit if we ever venture far outside our Solar System. The celestial object became even more intriguing in 2016 when astronomers found a planet orbiting around it. Called Proxima b, the planet is located in the star's habitable zone, where temperatures may be just right for water to pool on the surface. Just a few years later, a second planet, called Proxima c, was discovered around the star, too. With the discovery of this third likely exoplanet, called Proxima d, Proxima Centauri is possibly home to a wide array of worlds. While we do not have the means to travel to Proxima Centauri yet in any kind of reasonable time frame, these planets might be the first places we'd visit if we ever do develop such a capability. For now, their close proximity to Earth makes them prime candidates for follow-up study and observations. Astronomers say they could help us in our ever-evolving quest to understand how planets form around distant stars.

Douglas Trumbull, the visual effects mastermind behind Blade Runner, Close Encounter of the Third Kind, 2001: A Space Odyssey and numerous others, died on Monday at age 79. His daughter Amy Trumbull announced the news on Facebook, writing that her father's death followed a "two-year battle" with cancer, a brain tumor and stroke. Engadget reports: Trumbull was born on April 8, 1942 in Los Angeles, the son of a mechanical engineer and artist. His father worked on the special effects for films including The Wizard of Oz and Star Wars: A New Hope. The younger Trumbull worked as an illustrator and airbrush artist in Hollywood for many years. His career really took off after he cold-called Stanley Kubrick, a conversation which led to a job working on 2001: A Space Odyssey.

One of his most significant contributions to 2001 was creating the film's Star Gate, a ground-breaking scene where astronaut Dave Bowman hurtles through an illuminated tunnel transcending space and time. In order to meet Kubrick's high aesthetic standards for the shot, Trumbull essentially designed a way to turn the film camera inside-out. Trumbull's ad hoc technique "was completely breaking the concept of what a camera is supposed to do," he said during a lecture at TIFF. Trumbull earned visual effects Oscar nominations for his work on Close Encounters, Star Trek: The Motion Picture and Blade Runner. He also received the President's Award from the American Society of Cinematographers in 1996.

Later in his career, Trumbull voiced distaste over the impact of computers on visual effects, decrying the cheapening and flattening impact of the new era of CGI. [...] He spent the last years of his life working on a new super-immersive film format he dubbed MAGI, which he believed would improve the experience of watching a film in theaters. But Trumbull struggled to draw the interest of today's film industry.

Last week a Chinese satellite "was observed grabbing another satellite and pulling it out of its normal geosynchronous orbit," reports the Drive, "and into a 'super-graveyard drift orbit.'"

"The maneuver raises questions about the potential applications of these types of satellites designed to maneuver close to other satellites for inspection or manipulation and adds to growing concerns about China's space program overall." On January 22, China's Shijian-21 satellite, or SJ-21, disappeared from its regular position in orbit during daylight hours when observations were difficult to make with optical telescopes. SJ-21 was then observed executing a "large maneuver" to bring it closely alongside another satellite, a dead BeiDou Navigation System satellite. SJ-21 then pulled the dead satellite out of its normal geosynchronous orbit and placed it a few hundred miles away in what is known as a graveyard orbit. These distant orbits are designated for defunct satellites at the end of their lives and are intended to reduce the risk of collision with operational assets....

According to Chinese state news outlets, SJ-21 was designed to "test and verify space debris mitigation technologies."

SJ-21's recent maneuver raises questions and concerns about these types of satellites and their potential for military use. Todd Harrison, director of CSIS's Aerospace Project, told Breaking Defense that SJ-21's actions present "more questions than answers," adding that while we can observe the satellite's actions, "the intent behind it and what China plans to do with this technology is a more subjective assessment."

This isn't the first time SJ-21 has made headlines with its questionable behavior. In November 2021, just a month after its launch, an unknown object was seen orbiting alongside SJ-21. At the time, Space Force designated the unidentified object as a spent apogee kick motor, but it was also reported that it might have been an experimental payload designed to test SJ-21's ability to perform remote operations and manipulate other satellites....

Analyzing the potential applications of these dual-use satellites is difficult.

Astronomers said this week that a piece of a Falcon 9 rocket that was launched in February 2015 is currently on a trajectory to collide with the moon in just a few weeks. CBS News reports: The rocket left from Florida's Cape Canaveral and launched NOAA's Deep Space Climate Observatory, a project that allows researchers to maintain real-time data for more accurate space weather alerts and forecasts. According to NOAA, having that data is "critical," as space weather events "have the potential to disrupt nearly every major public infrastructure system on Earth." During that deployment, Falcon 9's second stage, which provides it with a second boost to reach its desired orbit, ran out of fuel to return to Earth, according to meteorologist and Ars Technica space editor Eric Berger. The second stage has been orbiting Earth ever since, and now, according to data gathered by astronomers, it's on track to hit the moon.

Bill Gray, who writes the Project Pluto software that is used by both amateur and professional astronomers, gathered data from those space observers over the past few weeks to predict just when the impact will occur. Based on the information he gathered, there will be a "certain impact" with the far side of the moon on March 4, he said. The rocket stage is currently floating away from Earth and outside of the moon's orbit on a "chaotic" orbit, Gray said, but in the coming days, it's expected to turn around and head back towards Earth. It made a "close lunar flyby" on January 5, but March 4 is when its path and the moon's will cross. Thankfully, there's no cause for concern, says Gray, noting that it's the "first unintentional case" of space junk hitting the moon that he's aware of. It may actually help researchers learn more about the moon's makeup if lunar orbiters are able to observe the crash site.

"If we can tell the [lunar orbiter] folks exactly where the crater is, they'll eventually pass over that spot and be able to see a very fresh impact crater and probably learn something about the geology (well, selenology) of that part of the moon," Gray said.

While mapping radio waves across the universe, astronomers happened upon a celestial object releasing giant bursts of energy -- and it's unlike anything they've ever seen before. From a report: The spinning space object, spotted in March 2018, beamed out radiation three times per hour. In those moments, it became the brightest source of radio waves viewable from Earth, acting like a celestial lighthouse. Astronomers think it might be a remnant of a collapsed star, either a dense neutron star or a dead white dwarf star, with a strong magnetic field -- or it could be something else entirely. A study on the discovery published Wednesday in the journal Nature. "This object was appearing and disappearing over a few hours during our observations," said lead study author Natasha Hurley-Walker, an astrophysicist at the Curtin University node of the International Centre for Radio Astronomy Research, in a statement. "That was completely unexpected. It was kind of spooky for an astronomer because there's nothing known in the sky that does that. And it's really quite close to us -- about 4,000 light-years away. It's in our galactic backyard."

An anonymous reader quotes a report from The Drive: Space Force launched two additional satellites today as part of its push for greater Space Domain Awareness, or SDA, in geosynchronous orbit some 22,000 miles away from Earth. The two satellites are part of the Geosynchronous Space Situational Awareness Program, or GSSAP, and will allow Space Force to not only locate and identify objects in this distant orbit, but also maneuver close to them in order to inspect them or assess their capabilities. The launch comes as Space Force leadership continues to sound the alarm about the risks posed to U.S. satellites in orbit.

The Northrop Grumman-built GSSAP-5 and GSSAP-6 were launched today at Cape Canaveral Space Force Station in Florida atop a United Launch Alliance (ULA) Atlas V 511 rocket. The first two GSSAP satellites were launched in 2014, with the second two following in 2016. Space Force has not released any details about how these two new GSSAP satellites might differ from the previous four, which were designed to operate near the belt of other geosynchronous satellites and maneuver close to them to conduct surveillance. A spokesperson for Space Systems Command stated this week that the new GGSAP satellites "will provide improved SDA data to the National Space Defense Center and other national users to enhance our ability to navigate freely and safely within the GEO belt."

GSSAP-5 and GSSAP-6 were originally scheduled to be launched in 2020, and it is not known why the launch was delayed almost two years. The GSSAP program was originally highly classified and was only revealed to the public in 2014. While the exact capabilities of the satellites are not public, it's known that they are able to capture close-up images of other satellites in geosynchronous orbit. Former Commander of Air Force Space Command Gen. William Shelton (Ret.) told Aviation Week in 2014 that the satellites are designed to drift in and out of the geosynchronous belt collecting intelligence on specific targets. The Air Force has previously used one of the satellites for Remote Proximity Operations (RPO), maneuvering close enough to inspect another Department of Defense satellite operated by the Navy that was experiencing a malfunction. The former head of Air Force Space Command, General John Hyten (Ret.), has previously said the satellites are capable of capturing some "truly eye-watering" imagery.
