Slashdot reader XXongo brings word of a new three-part documentary — streaming free now — that tries to understand America's early inaction on climate change. Looking back over the last few decades, The Power of Big Oil explores how the fuel industry "successfully set up a campaign to discredit climate science and targetting individual politicians to vote against measures to curb climate change."

The Guardian notes that the series includes an interview with a U.S. senator who they say "blames the oil industry for malignly claiming the science of climate change was not proved when companies such as Exxon and Shell already knew otherwise from their own research."

As far back as 25 years ago, the senator says, "they had evidence in their own institutions that countered what they were saying publicly. I mean — they lied." The documentary's makers have dug out a parade of former oil company scientists, lobbyists and public relations strategists who lay bare how the US's biggest petroleum firm, Exxon, and then the broader petroleum industry, moved from attempting to understand the causes of a global heating to a concerted campaign to hide the making of an environmental catastrophe. Over three episodes — called Denial, Doubt, Delay — the series charts corporate manipulation of science, public opinion and politicians that mirrors conduct by other industries, from big tobacco to the pharmaceutical companies responsible for America's opioid epidemic.

Some of those interviewed shamefacedly admit their part in the decades-long campaign to hide the evidence of climate change, discredit scientists and delay action that threatened big oil's profits.

Others almost boast about how easy it was to dupe the American public and politicians, with consequences not just for the US but every country on the planet.
In one video clip an aide to a climate-conscious senator remembers that "You had reams of material coming out of the government. They were at the National Oceanic and Atmospheric Administration, at NASA — this expanding network of people, working on this day in and day out, saying that this was a legitimate issue, and that we needed to do something about it. And on the other hand, you had two or three guys who went around to conferences and said, 'Oh, I'm not sure. Oh, maybe there's clouds....' It quickly became apparent that these were private interests who had a stake in the status quo." He refers to it as "emerging industry of nay-sayers."

There's also a discouraged assessment from climate activist looking back over a lack of progress in the early decades. "You want to make an assumption that it's a meritocracy — a good argument will prevail, and it will displace a bad argument. But, what the geniuses at the PR firms who work for these big fossil-fuel companies know is that truth has nothing to do with who wins the argument. If you say something enough times, people will begin to believe it."

In 1972 — half a century ago — Charles Moss Duke walked on the moon.

Now 86 years old, he's ready for America to get back to exploring the moon, reports the Associated Press: Duke said he does not begrudge NASA for ending the Apollo program to focus on space shuttles, the international space station and other missions in more remote parts of space. But he looks forward to future missions that build off of what he and others have learned from their time on the moon, which called "a great platform for science."

Duke also noted that he's encouraged by the commercial partnerships that have developed around space exploration, like Space X and Blue Origin [and the companies he describes in their video as "the others"]. Those options, he said, "make space available for more people and more science and engineering and unmanned stuff."

"That compliment is going to be really important in the future," Duke went on.
The article notes the first of NASA's huge Space Launch System rockets is scheduled to blast off later this year, "with crewed flights planned subsequently." In the video interview, Duke adds that "With Artemis, NASA is going to be focused on deep space, to the moon and beyond, and I'm excited about that..."

"The more people we get into space, and can see the beauty of the earth — and the incredible emotion that you [feel] when you see the earth hung in the blackness of space — it's going to affect a lot of people."

Long-time Slashdot reader schwit1 shares a report from Inverse: It only took 25 years of development, 17 years of construction, eight launch delays, and five months of alignments, but finally, the James Webb Space Telescope is almost ready for prime time. New photos released by the European Space Agency — and an accompanying video from NASA — show images of stars taken by a fully aligned space telescope, instruments and all.

The image shows snapshots from each of Webb's three imaging instruments, plus its spectrograph and guidance sensor. The images show a field of stars in the Large Magellanic Cloud (LMC), a galaxy near the Milky Way about 158,000 light-years away. If it orbits our galaxy, it would be, by far, the largest satellite galaxy. But there's a chance it's just passing through or slowly merging with our galaxy.

New pictures from the Ingenuity helicopter offer a fresh perspective of the wreckage left behind when the Perseverance rover landed on Mars last year, NASA said on Wednesday. The Verge reports: Launched in 2020, the Perseverance rover successfully landed on the Red Planet in 2021, with the mission of finding ancient signs of life on Mars. The rover carried the Ingenuity helicopter onboard -- an experimental project that scientists on Earth hoped would be able to see sights that the rover couldn't. Perseverance went through a grueling process known as the seven minutes of terror to descend onto the Martian surface. As it entered the atmosphere, a heat shield helped protect the rover from the blistering heat of reentry and slowed it down dramatically. After that, the massive parachute deployed out of the backshell (a cone-shaped part of the descent vehicle), slowing it down even more. At that point, the backshell and parachute separated from Perseverance and let the descent stage take over, using rocket thrusters and a "sky crane" to gently lower the rover to a smooth landing.

On April 19th, Ingenuity took photographs that captured the remains of Perseverance's parachute and the rover's protective backshell, a cone-shaped part of the descent vehicle that carried the parachute and helped protect the rover on its way to the surface. Strewn around the site were debris from where the two crashed into the surface after separating from the rover. The backshell ended up hitting the ground at about 78 miles per hour, according to NASA. From the pictures, it appears that the parachute, the lines connecting the parachute to the spacecraft, and the coating on the outside of the backshell all survived the trip to the surface, NASA says, though more analysis of the pictures will happen in the coming weeks.

vm shares a report from Space.com: SpaceX is among companies that might replace services of NASA's aging space telecoms constellation that has kept the International Space Station connected to Earth for decades. For years, NASA's Tracking and Data Relay Satellite (TDRS) constellation has served as the main link between the International Space Station and Earth, providing astronauts with constant connection to ground control as well as the ability to engage with the public and stay in touch with their loved ones. The American space agency, however, plans to retire the six aging satellites in the next decade and hand over their task to commercial companies. This month, the agency announced partnerships with six commercial satellite operators including SpaceX, U.K. company Inmarsat, American Viasat and Switzerland-based SES, to demonstrate how they could take care of NASA's space communication needs in the future. "We don't plan to launch any new TDRS satellites in the future," Eli Naffah, the manager of NASA's Commercial Services Project, who oversees the partnership with the commercial companies, told Space.com. "The plan is to allow the constellation to basically [reach the end of its life]. At some point later in this decade, we are going to have some diminished capability and the plan is for the [commercial companies] to come up with a different way of providing communication services to our missions."

"Back in the 1980s, when we developed TDRS, there really wasn't an ability on the commercial side to be able to provide this service," Naffah said. "But since then, the industry has far outpaced NASA's investment in this area. There's a lot of infrastructure, both on the ground and in orbit that is capable of providing these types of services to a spacecraft. [...] Hopefully, we can achieve some cost efficiencies in buying commercial services, get out of the business of operating networks, and really put more focus on science and exploration." According to Naffah, NASA will invest $278 million into the project over the next five years, with the agency's industry partners contributing a total of about $1.5 billion.

Maine is closer to launching its space program after Gov. Janet Mills signed a bill to create the Maine Space Port, a law aimed at growing the state's aerospace industry. From a report: Mills signed the bill into law on April 19, creating a public-private partnership that would build launch sites, data networks and operations to send satellites into space, The Portland Press Herald reported Sunday. Most of the work accomplished at the program will be through the creation of the Maine Space Complex which will be built at the former Brunswick Naval Air Station within the next decade. The complex will oversee three entities including a computer center and satellite launch and operations sites. Terry Shehata, director of the Maine Space Grant Consortium, said the spaceport would be one of the first in the U.S. to launch satellites, conduct data analysis and provide education to students. The consortium is the NASA-funded nonprofit spearheading the spaceport complex.

The seismometer placed on Mars by NASA's InSight lander has recorded its two largest seismic events to date: a magnitude 4.2 and a magnitude 4.1 marsquake. Phys.Org reports: The pair are the first recorded events to occur on the planet's far side from the lander and are five times stronger than the previous largest event recorded. Seismic wave data from the events could help researchers learn more about the interior layers of Mars, particularly its core-mantle boundary, researchers from InSight's Marsquake Service (MQS) report in The Seismic Record.

Anna Horleston of the University of Bristol and colleagues were able to identify reflected PP and SS waves from the magnitude 4.2 event, called S0976a, and locate its origin in the Valles Marineris, a massive canyon network that is one of Mars' most distinguishing geological features and one of the largest graben systems in the Solar System. Earlier orbital images of cross-cutting faults and landslides suggested the area would be seismically active, but the new event is the first confirmed seismic activity there.

S1000a, the magnitude 4.1 event recorded 24 days later, was characterized by reflected PP and SS waves as well as Pdiff waves, small amplitude waves that have traversed the core-mantle boundary. This is the first time Pdiff waves have been spotted by the InSight mission. The researchers could not definitively pinpoint S1000a's location, but like S0976a it originated on Mars' far side. The seismic energy from S1000a also holds the distinction of being the longest recorded on Mars, lasting 94 minutes.

An anonymous reader quotes a report from the Associated Press: The Biden administration is calling on Congress to expand authority for federal and local governments to take action to counter the nefarious use in the U.S. of drones, which are becoming a growing security concern and nuisance. The White House on Monday released an action plan that calls for expanding the number of agencies that can track and monitor drones flying in their airspace. It calls for establishing a list of U.S. government-authorized detection equipment that federal and local authorities can purchase, and creating a national training center on countering the malicious use of drones. The White House in a statement said it was critical that Congress "adopt legislation to close critical gaps in existing law and policy that currently impede government and law enforcement from protecting the American people and our vital security interests."

The federal-government-wide focus comes as the Federal Aviation Administration projects that more than 2 million drones will be in circulation in the U.S. by 2024 and as availability of detection and mitigation technologies -- including jamming systems -- are limited under current law. The White House plan calls for expanding existing counter-drone authorities for the departments of Homeland Security, Justice, Defense, Energy, as well as the Central Intelligence Agency and NASA in limited situations. The proposal also seeks to expand drone detection authorities for state, local, territorial and tribal law enforcement agencies and critical infrastructure owners and operators. The proposal also calls for establishing a six-year pilot program for a small number of state, local, territorial and tribal law enforcement agencies to take part in a drone detection and mitigation operations under supervision of the Justice Department and Homeland Security. Currently, no state or local agencies have such authorization.

The global effort to protect Earth from dangerous asteroids is set to become stronger, as China has announced its intentions to test an asteroid redirect system as early as 2025. Reader InfiniteZero writes: Speaking to China Central Television on Sunday, Wu Yanhua, deputy head of the China National Space Administration (CNSA), described China's preliminary plans to embark on the planetary defense project, according to Chinese state-owned news agency Global Times. Wu's comments coincided with Space Day, an annual event that commemorates the 1970 launch of China's first satellite, Dongfanghong-1, in 1970. For the proposed test, Wu said a probe would closely survey a near-Earth object prior to smashing into it. Known as kinetic impaction, the idea is to alter the orbital trajectory of a threatening asteroid by directing a large, high-speed spacecraft into the object. NASA is currently running a similar test, known as the Double Asteroid Redirection Test, or DART, which seeks to deliberately crash a space probe into Dimorphos -- a tiny asteroid -- later this year.

Once every 10 years there's a report released by America's National Academies of Sciences, Engineering, and Medicine.

Released this year, the report recommends prioritizing a mission to the planet Uranus to map its gravitational and magnetic fields and study how the planet's internal heat moves to the surface.

BGR reports: Despite being the seventh planet in our solar system, there's very little we know about Uranus as a whole. In fact, one of the best images we have of the planet was captured in 1986 by the Voyager 2... Additionally, scientists want to learn more about the various moons that surround the planet. We also know very little about the ring system that surrounds the blue planet. A team led by Mark Hofstadter, a planetary scientist with NASA's Jet Propulsion Lab wrote a white paper on their goals....

We currently already have the tech we need to get a spacecraft there that can orbit the planet. Additionally, scientists have found that launching a mission in 2031 would allow us to capitalize on gravity assistance from Jupiter.
The report also recommends studying Enceladus, an icy moon orbiting Saturn which has shown signs it could sustain microbial life.

After startup Axiom Space brokered the first visit to the Space Station by an all-private crew, the AX-1 mission turned into a "longer-than-expected" stay, reports CNN. It launched on April 8 and "was originally billed as a 10-day mission," CNN notes, "but delays have extended the mission by about a week." The four crew members — Michael López-Alegría, a former NASA astronaut-turned-Axiom employee who is commanding the mission; Israeli businessman Eytan Stibbe; Canadian investor Mark Pathy; and Ohio-based real estate magnate Larry Connor — are slated to leave the space station aboard their SpaceX Crew Dragon capsule on Sunday at 8:55 pm ET. That's another 24-hour delay from what NASA and Axiom were targeting on Saturday. They now plan to spend a day free flying through orbit before plummeting back into the atmosphere and parachuting to a splashdown landing off the coast of Florida at about 1 pm ET Monday, according to a tweet from Kathy Lueders, the head of NASA's human spaceflight program...

During their first 12 days on the space station, the group stuck to a regimented schedule, which included about 14 hours per day of activities, including scientific research that was designed by various research hospitals, universities, tech companies and more. They also spent time doing outreach events by video conferencing with children and students. The weather delays then afforded to them "a bit more time to absorb the remarkable views of the blue planet and review the vast amount of work that was successfully completed during the mission," according to Axiom....

It's not the first time paying customers or otherwise non-astronauts have visited the ISS, as Russia has sold seats on its Soyuz spacecraft to various wealthy thrill seekers in years past. But AX-1 is the first mission with a crew entirely comprised of private citizens with no active members of a government astronaut corps accompanying them in the capsule during the trip to and from the ISS. It's also the first time private citizens have traveled to the ISS on a US-made spacecraft.

In 2021, a team of hologram doctors was "holoported" to space to visit astronauts living aboard the International Space Station, NASA has revealed in a new post. Space.com reports: The hologram teams, led by NASA flight surgeon Dr. Josef Schmid and Fernando De La Pena Llaca, CEO of software provider Aexa Aerospace, were the first humans to ever be "holoported" from Earth to space. "This is completely new manner of human communication across vast distances," Schmid said in the statement. "Furthermore, it is a brand-new way of human exploration, where our human entity is able to travel off the planet. Our physical body is not there, but our human entity absolutely is there."

"It doesn't matter that the space station is traveling 17,500 mph [28,000 kilometers per hour] and in constant motion in orbit 250 miles [400 km] above Earth, the astronaut can come back three minutes or three weeks later and with the system running, we will be there in that spot, live on the space station," Schmid added. The medical teams holoported to the station on Oct. 8. Using the Microsoft Hololens Kinect camera and a personal computer with custom Aexa software, European Space Agency astronaut Thomas Pesquet, who was on board the station at that time, had a holo-conversation with Schmid and De La Pena's teams. The holograms of the doctors were visible live in the middle of the space station.

So how did it work? The "holoportation" technology that enabled this event works using specialized image capture technology that reconstructs, compresses and transmits live 3D models of people. This technology couples with the HoloLens, a self-described "mixed reality headset" that combines sensors, optics and holographic processing tech to allow the wearer to see the hologram images or even enter a "virtual world." With the two systems combined, users in orbit can not only see hologram participants, but can also hear and interact with them. The technology is not new, but has never been used in an environment this challenging with users so far apart.

Beacon of Galaxy message could be sent into heart of Milky Way, where life is deemed most likely to exist. From a report: "Even if the aliens are short, dour and sexually obsessed," the late cosmologist Carl Sagan once mused, "if they're here, I want to know about them." Driven by the same mindset, a Nasa-led team of international scientists has developed a new message that it proposes to beam across the galaxy in the hope of making first contact with intelligent extraterrestrials. The interstellar missive, known as the Beacon in the Galaxy, opens with simple principles for communication, some basic concepts in maths and physics, the constituents of DNA, and closes with information about humans, the Earth, and a return address should any distant recipients be minded to reply.

The group of researchers, headed by Dr Jonathan Jiang at Nasa's Jet Propulsion Laboratory in California, says that with technical upgrades the binary message could be broadcast into the heart of the Milky Way by the Seti Institute's Allen Telescope Array in California and the 500-metre Aperture Spherical Radio Telescope in China. In a preliminary paper, which has not been peer reviewed, the scientists recommend sending the message to a dense ring of stars near the centre of the Milky Way -- a region deemed most promising for life to have emerged.

"Humanity has, we contend, a compelling story to share and the desire to know of others -- and now has the means to do so," the scientists write. The message, if it ever leaves Earth, would not be the first. The Beacon in the Galaxy is loosely based on the Arecibo message sent in 1974 from an observatory of the same name in Puerto Rico. That targeted a cluster of stars about 25,000 light years away, so it will not arrive any time soon. Since then, a host of messages have been beamed into the heavens including an advert for Doritos and an invitation, written in Klingon, to a Klingon Opera in The Hague.

"Astronomers have discovered a dusty, red object 13 billion light-years from Earth that may be the earliest known ancestor of a supermassive black hole," reports Live Science: The ancient object shows characteristics that fall between dusty, star-forming galaxies and brightly glowing black holes known as quasars, according to the authors of a new study, published April 13 in the journal Nature. Born just 750 million years after the Big Bang, during an epoch called the "cosmic dawn," the object appears to be the first direct evidence of an early galaxy weaving stardust into the foundations of a supermassive black hole.

Objects like these, known as transitioning red quasars, have been theorized to exist in the early universe, but they have never been observed — until now....

Prior research has shown that quasars existed within the first 700 million years of the universe, the study authors wrote; however, it's unclear exactly how these supermassive objects formed so quickly after the Big Bang. Simulations suggest that some sort of fast-growing transition phase occurs in dusty, star-dense galaxies. "Theorists have predicted that these black holes undergo an early phase of rapid growth: a dust-reddened compact object emerges from a heavily dust-obscured starburst galaxy," study co-author Gabriel Brammer, an associate professor at the Niels Bohr Institute, said in the statement. In their new paper, the researchers claim to have detected one of these rare transitional objects — officially named GNz7q — while studying an ancient, star-forming galaxy with the Hubble Space Telescope.

The team caught the early galaxy in the midst of a stellar baby boom, with the galaxy seemingly churning out new stars 1,600 times faster than the Milky Way does today. All those newborn stars produced an immense amount of heat, which warmed the galaxy's ambient gas and caused it to glow brightly in infrared wavelengths. The galaxy became so hot, in fact, that its dust shines brighter than any other known object from the cosmic dawn period, the researchers said. Amid that brightly glowing dust, the researchers detected a single red point of light — a large, compact object tinged by the enormous fog of dust around it. According to the researchers, this red dot's luminosity and color perfectly match the predicted characteristics of a transitioning red quasar....

[T]here are likely many, many others like it just waiting to be discovered by telescopes that can peer even further back, into the earliest eras of the universe. NASA's James Webb Space Telescope, which launched on Dec. 25, 2021, will be able to hunt for these elusive objects with much greater clarity than Hubble, the researchers wrote, hopefully shedding a bit more light onto the dusty cosmic dawn.

"After three attempts to complete a critical fueling test of the Space Launch System rocket, NASA has decided to take a break," reports Ars Technica: On Saturday night the space agency announced plans to roll the large SLS rocket from the launch pad at Kennedy Space Center to the Vehicle Assembly Building in the coming days. This marks a notable step back for the program, which has tried since April 1 to complete a "wet dress rehearsal" test, during which the rocket is fueled and brought to within 10 seconds of launch. The decision comes after three tries during the last two weeks. Each fueling attempt was scuttled by one or more technical issues with the rocket, its mobile launch tower, or ground systems that supply propellants and gases. During the most recent attempt, on Thursday April 14, NASA succeeded in loading 49 percent of the core-stage liquid oxygen fuel tank and 5 percent of the liquid hydrogen tank. [NASA reports that the team ended the test after "observing a liquid hydrogen leak on the tail service mast umbilical."]

While this represents progress, it did not include the most dynamic portion of the test, during which the rocket is fully fueled and pressurized; and it, the ground systems, and computer systems are put into a terminal countdown when every variable is closely monitored. NASA had hoped to complete this wet dress rehearsal test to work out the kinks in the complicated launch system so that, when the rocket is rolled out later this year for its actual launch, the countdown will proceed fairly smoothly. NASA said that its contractors, as well as its agency's, will use the next several weeks to address problems that cropped up during the fueling tests when the SLS rocket returns to the large Vehicle Assembly Building. For example, gaseous nitrogen system supplier Air Liquide will upgrade its capabilities. NASA will also replace a faulty check valve on the upper stage of the rocket, as well as fix a leak on the mobile launch tower's "tail service mast umbilical," a 10-meter-tall structure that provides propellant and electricity lines to the rocket on the pad....

Still, NASA seems confident that it will get through this painful teething process for the SLS rocket: a program that is now 11 years old and in which NASA has invested more than $30 billion in the rocket and ground systems now being tested. "There's no doubt in my mind that we will finish this test campaign, and we will listen to the hardware, and the data will lead us to the next step," Blackwell-Thompson said Friday. "And we will take the appropriate steps, and we will launch this vehicle. I don't know exactly what that date is, but there's no doubt in my mind that we'll finish the test campaign, and we will be ready to go fly."

"The U.S. Space Command announced this week that it determined a 2014 meteor hit that hit Earth was from outside the solar system," reports CBS News. "The meteor streaked across the sky off the coast of Manus Island, Papua New Guinea three years earlier than what was believed to be the first confirmed interstellar object detected entering our solar system."

After Oumuamua was spotted in 2017, the interstellar comet Borisov appeared in 2019 — discovered in Crimea, Ukraine at a "personal observatory" built by amateur astronomer Gennadiy Borisov"

But CBS notes that despite their theory about a first interstellar meteor in 2014, the two Harvard astronomers — Dr. Amir Siraj and Dr. Abraham Loeb — "had trouble getting their paper published, because they used classified information from the government." Specifically, data from a classified U.S. government satellite designed to detect foreign missiles... The meteor was unusual because of its very high speed and unusual direction — which suggested it came from interstellar space.... Any space object traveling more than about 42 kilometers per second may come from interstellar space. The data showed the 2014 Manus Island fireball hit the Earth's atmosphere at about 45 kilometers per second, which was "very promising" in identifying it as interstellar, Siraj said....

After more research and help from other scientists, including classified information from the government about the accuracy or level of precision of the data, Siraj and Loeb determined with 99.999% certainty the object was interstellar. But their paper on the finding was being turned down, because the pair only had a private conversation with an anonymous U.S. government employee to confirm the accuracy of the data.
"We had thought this was a lost cause," Dr. Siraj told the New York Times — which couldn't resist adding that "it turned out, the truth was out there." Last month, the U.S. Space Command released a memo to NASA scientists that stated the data from the missile warning satellites' sensors "was sufficiently accurate to indicate an interstellar trajectory" for the meteor. The publication of the memo was the culmination of a three-year effort by Siraj and a well-known Harvard astronomer, Avi Loeb.

Many scientists, including those at NASA, say that the military still has not released enough data to confirm the interstellar origins of the space rock, and a spokesperson said Space Command would defer to other authorities on the question.

But it wasn't the only information about meteors to be released. The military also handed NASA decades of secret military data on the brightness of hundreds of other fireballs, or bolides. "It's an unusual degree of visibility of a set of data coming from that world," said Matt Daniels, assistant director for space security at the White House's Office of Science and Technology Policy, who worked on the data release. "We're in this renewed period of excitement and activity in space programs generally, and in the midst of that, I think thoughtful leaders in multiple places said, 'you know, now is a good time to do this.'"
The Times notes that data from classified military satellites "could also aid NASA in its federally assigned role as defender of planet Earth from killer asteroids. And that is the goal of a new agreement with the U.S. Space Force that aims to help NASA's Planetary Defense Coordination Office better understand what happens when space rocks reach the atmosphere." Sharing sensitive military satellite data with astronomers has led to significant scientific discoveries in the past.

A group of satellites deployed in the 1960s by the United States to detect covert detonations of nuclear weapons on Earth accidentally became the key instruments used to make the first detection of extraterrestrial gamma ray bursts. The bursts showed up on the satellites, code-named Vela, as single bursts of energy, confusing analysts at Los Alamos who later declassified the data in a 1973 paper that spurred academic debate about the bursts' origins....

A core reason for Space Force's increasing ties with NASA has centered on the agency's congressional mandate to detect nearly all asteroids that could threaten the Earth. When NASA signed an agreement in 2020 to strengthen ties with Space Force, the agency acknowledged it had fallen behind in its asteroid-tracking efforts and would need Pentagon resources to carry out its planetary defense mission.

NASA's Hubble Space Telescope has confirmed the largest icy comet nucleus ever seen by scientists. NPR reports: The nucleus of comet C/2014 UN271 (Bernardinelli-Bernstein) is about 80 miles in diameter, which is larger than the state of Rhode Island, NASA says. The comet's nucleus is about 50 times larger than that of most comets, and its mass is estimated to be a gigantic 500 trillion tons.

Comet C/2014 UN271 was discovered by astronomers Pedro Bernardinelli and Gary Bernstein using archival images from the Cerro Tololo Inter-American Observatory in Chile. The comet has been observed since 2010, when it was 3 billion miles away from the sun, and has been studied since then. NASA says there was a challenge in measuring the comet's nucleus because it was too far away for the Hubble telescope to determine its size. Instead, scientists had to make a computer model that was adjusted to fit the images of the comet's bright light that they got from the telescope's data.

Despite traveling at 22,000 mph, the massive comet is still coming from the edge of the solar system. But NASA assures us that it will never get closer than 1 billion miles away from the sun -- and even then, that won't be until 2031. The previous record-holder for largest comet nucleus was discovered in 2002. Comet C/2002 VQ94 was approximately 60 miles across.

NASA has signed up to test SpinLaunch's extraordinary whirl 'n' hurl space launch technology, which accelerates a launch vehicle to hypersonic speeds using an electric centrifuge instead of a rocket, hurling it skyward like a space discus. New Atlas reports: The idea behind SpinLaunch is as staggering as the company's name is appropriate. The idea of winding up and throwing satellites most of the way into orbit just boggles the mind. But in initial testing, this company's kinetic launch system, which looks externally a lot like a turbocharger, has shown promise as an environmentally-friendly, and potentially cost-effective replacement for first-stage rocket launches. [T]he company says it'll be appropriate for smaller launch vehicles weighing up to about 440 lb (200 kg), carrying ultra-ruggedized satellites capable of dealing with the forces involved. The SpinLaunch system will do the first part, flinging them high into the air, where a second-stage rocket can take over and give them the final push into orbit.

And the advantages are pretty compelling. SpinLaunch says that eliminating the first-stage rocket from the launch vehicle will cut out some 70 percent of the fuel and structures needed by a traditional launch vehicle, and that it can get appropriate loads into orbit using a quarter of the fuel, and at a tenth of the price. NASA is one of many parties interested in this possibility, and it's now signed a Space Act agreement with SpinLaunch to develop and integrate a NASA payload for this kinetic launch system, which will be flung skyward from Spaceport America, New Mexico, in a test flight later this year.

This, like all SpinLaunch "regular" test flights to date, will be a slower sub-orbital launch with a speed closer to 1,000 mph (1,600 km/h, Mach 1.3) than 5,000 mph. The payload will be designed to take a range of measurements, which will be analyzed by both groups. All non-proprietary information learned from this test will be published, and SpinLaunch says it's working towards its first orbital launch in 2025. A render posted late last year by SpinLaunch shows how their system works.

An anonymous reader quotes a report from Ars Technica: Putin said Russia is working on a "next-generation transport ship," as well as a nuclear-powered space tug. And, according to Russian media reports, Putin added, "We will resume the lunar program." The next-generation ship presumably refers to the "Orel," or Eagle, spacecraft that would be capable of launching cosmonauts into low Earth orbit as well as to the Moon. The problem with this is that Orel, under various guises and names, has been in development for nearly two decades and is likely years away from flying -- if it ever does. And the nuclear-powered space tug is a concept that is years or more likely decades-to-never away from launching.

That leaves the lunar program Putin mentioned. He is referring to a series of three robotic missions planned for launch to the Moon, Luna 25, Luna 26, and Luna 27. These missions, too, have been in the planning stages for a long, long time. Luna 25 was originally scheduled to launch on a Soyuz rocket a decade ago, and its current launch date is now August 2022. There is reason to be skeptical about all of the above happening, because even before the war in Ukraine, Putin significantly slashed Roscosmos' budget. Now, more resources than ever will likely be devoted to the war effort. Hours after Putin made his announcements, the European Space Agency (ESA) Council agreed to discontinue cooperative activities with Russia on the three Luna missions. "The Russian aggression against Ukraine and the resulting sanctions put in place represent a fundamental change of circumstances and make it impossible for ESA to implement the planned lunar cooperation," the space agency said in a statement.

Instead, the council said it would now work with NASA and its commercial partners.

A SpaceX Crew Dragon safely delivered four private astronauts to the International Space Station this past Saturday. Gizmodo reports: SpaceX capsule Endeavor reached the ISS at 8:20 a.m. EDT on Saturday, April 9, following a nearly 21-hour journey. The crew of the Ax-1 mission -- Michael Lopez-Alegria, Larry Connor, Eytan Stibbe, and Mark Pathy -- launched atop a Falcon 9 rocket on Thursday from Kennedy Space Center in Florida. The ISS is currently orbiting at a height of 260 miles (418 km) above Earth. The docking would've happened 45 minutes earlier, had it not been for a problem having to do with ISS crew members not being able to receive video from the Crew Dragon's center line camera. Ground controllers remedied the problem by routing video from a SpaceX ground station, according to NASA.

The four crew members will stay on the orbital outpost for eight days, where they will perform some 25 experiments having to do with science, education, and commercial activities. Axiom Space is aiming to build the world's first fully commercial space station, the construction of which is slated to begin at the ISS in late 2024. The Ax-1 mission represents an important milestone in the ongoing commercialization of low Earth orbit. [...] Axiom said the first day was mostly about preparing equipment for what will be a very busy week. The team has just 100 hours to complete their respective tasks.
