US Must Beat China Back To the Moon, Congress Tells NASA (space.com) 114

With NASA's Artemis moon program now targeting September 2025 for its Artemis 2 mission and September 2026 for Artemis 3, some members of Congress are concerned about the potential repercussions, particularly with China's growing ambitions in lunar exploration. "For the United States and its partners not to be on the moon when others are on the moon is unacceptable," said Mike Griffin, former NASA administrator. "We need a program that is consistent with that theme. Artemis is not that program. We need to restart it, not keep it on track." Space.com reports: The U.S. House of Representatives' Committee on Science, Space and Technology held a hearing about the new Artemis plan today (Jan. 17), and multiple members voiced concern about the slippage. "I remind my colleagues that we are not the only country interested in sending humans to the moon," Committee Chairman Frank Lucas (R-OK) said in his opening remarks. "The Chinese Communist Party is actively soliciting international partners for a lunar mission -- a lunar research station -- and has stated its ambition to have human astronauts on the surface by 2030," he added. "The country that lands first will have the ability to set a precedent for whether future lunar activities are conducted with openness and transparency, or in a more restricted manner."

The committee's ranking member, California Democrat Zoe Lofgren (D-CA), voiced similar sentiments. "Let me be clear: I support Artemis," she said in her opening remarks. "But I want it to be successful, especially with China at our heels. And we want to be helpful here in the committee in ensuring that Artemis is strong and staying on track as we look to lead the world, hand-in-hand with our partners, in the human exploration of the moon and beyond." Several other committee members stressed that the new moon race is part of a broader competition with China, and that coming in second could imperil U.S. national security.

"It's no secret that China has a goal to surpass the United States by 2045 as global leaders in space. We can't allow this to happen," Rich McCormick (R-GA) said during the hearing. "I think the leading edge that we have in space technology will protect the United States -- not just the economy, but technologies that can benefit humankind." And Bill Posey (R-FL) referred to space as the "ultimate military high ground," saying that whoever leads in the final frontier "will control the destiny of this Earth."

Private US Moon Lander Now Headed For Earth, Might Burn Up In Atmosphere (ndtv.com) 41

The fuel-leaking Peregrine lunar lander is now "on a parth towards Earth," according to Update #16 from Astrobotic, which predicts their spacecraft "will likely burn up in the Earth's atmosphere." "Our analysis efforts have been challenging due to the propellant leak... The team is currently assessing options and we will update as soon as we are able. The propellant leak has slowed considerably to a point where it is no longer the teams' top priority...

We have now been operating in space for 5 days and 8 hours and are about 242,000 miles from Earth.

"A soft landing on the Moon is not possible," the announcement emphasizes. NDTV explains: Shortly after it separated from the rocket, the spaceship experienced an onboard explosion and it soon became clear it would not make a soft lunar touchdown because of the amount of the propellant it was losing — though Astrobotic's team were able to power up science experiments they were carrying for NASA and other space agencies, and gather spaceflight data...

Astrobotic itself will get another chance in November with its Griffin lander transporting NASA's VIPER rover to the lunar south pole.

NASA Finally Unlocks Stuck Fasteners on Asteroid Sample Capsule (space.com) 37

"For months, bits of an asteroid collected by a U.S. probe during a billion-mile trek were out of reach to scientists," reports Space.com, "locked inside a return capsule in a NASA facility with two stuck fasteners preventing access to the rocky space treasure.

"This week, NASA won its battle against those fasteners."

More details from CNN: The space agency already harvested about 2.5 ounces (70 grams) of rocks and dust from its OSIRIS-REx mission, which traveled nearly 4 billion miles to collect the unprecedented sample from the near-Earth asteroid called Bennu. But NASA revealed in October that some material remained out of reach in a capsule hidden inside an instrument called the Touch-and-Go Sample Acquisition Mechanism — a robotic arm with a storage container at one end that collected the sample from Bennu. The sampler head is held shut by 35 fasteners, according to NASA, but two of them proved too difficult to open.

Prying the mechanism loose is no simple task. The space agency must use preapproved materials and tools around the capsule to minimize the risk of damaging or contaminating the samples. These "new tools also needed to function within the tightly-confined space of the glovebox, limiting their height, weight, and potential arc movement," said Dr. Nicole Lunning, OSIRIS-REx curation lead at NASA's Johnson Space Center in Houston, in a statement. "The curation team showed impressive resilience and did incredible work to get these stubborn fasteners off the TAGSAM head so we can continue disassembly. We are overjoyed with the success."

To address the issue, NASA said they designed and fabricated two new, multi-part tools out of surgical steel. NASA says that a "few additional disassembly steps" still remain, but there's a video on their web site showing the operation (along with some pictures).

NASA adds that "Later this spring, the curation team will release a catalog of the OSIRIS-REx samples, which will be available to the global scientific community." But CNN notes that an analysis of material from last fall "already revealed the samples from the asteroid contained abundant water in the form of hydrated clay minerals as well as carbon," CNN reports. And they add that scientists believe this bolsters the theory that water arrived on Earth billions of years ago on an asteroid...

NASA Unveils Revolutionary X-59 'Quiet' Supersonic Aircraft (space.com) 90

After years of development, NASA has unveiled the X-59 supersonic jet capable of breaking the sound barrier without producing a thunderous sonic boom. "Instead, the Quesst will make a much quieter 'thump,' similar to the sound of a car door slamming as heard from indoors," reports Space.com. "If successful, the jet has the potential to revolutionize supersonic flight and aviation in general." From the report: NASA and Lockheed Martin showed off the finished X-59 Quesst ("Quiet SuperSonic Technology") today (Jan. 12) in front of a crowd of nearly 150 at the legendary Lockheed Martin Skunk Works facility in Palmdale, California, a research and development site typically known for its secrecy. The elongated beak-like nose section of the aircraft stood out prominently, showing off the fact that it does not have a forward-facing window. [...] Instead, it features what NASA calls the eXternal Vision System, or XVS, which consists of a camera and a cockpit-mounted screen that offers pilots an augmented-reality view of what's in front of the jet.

Jim Free, NASA's associate administrator, continued this sentiment, noting that the X-59 is merely the latest in a long line of NASA X-planes that have revolutionized aviation throughout the agency's history. "Even among other X-planes, the X-59 is special. Every aircraft that receives that X-plane designation has a specific purpose to test new technologies or aerodynamic concepts," Free said, "These special planes push the envelope of what's possible in flight. And once they prove those concepts, they often go into museums. And that's really what makes the X-59 different."

Free was referring to the fact that once the X-59 is ready for flight, the jet will make multiple flights over select residential areas in the United States in order to collect data on how people on the ground below experience and react to the quieter sonic booms it creates. NASA will then use that data to seek approval for commercial supersonic flights from regulatory agencies such as the Federal Aviation Administration, with the ultimate goal of making aviation more sustainable and enabling faster flight over populated areas. Some of the applications of supersonic flight mentioned at today's unveiling include rapid medical response, shorter shipping times and, of course, faster travel.
"The first 'A' in NASA stands for aeronautics," said NASA Deputy Administrator Pam Melroy during the unveiling ceremony. "And we're all about groundbreaking aerospace innovation. The X-59 proudly continues this legacy, representing the forefront of technology driving aviation forward." The 'X' in NASA's latest X-plane stands for 'experimental.'

"This isn't just an airplane, this is an X-plane," Melroy added. "It's the manifestation of a collaborative genius."

2023 Was Hottest Year Ever Recorded Globally, US Scientists Confirm (theguardian.com) 114

Last year was the hottest ever reliably recorded globally by a blistering margin, US scientists have confirmed, leaving researchers struggling to account for the severity of the heat and what it portends for the unfolding climate crisis. From a report: Last year was the world's hottest in records that stretch back to 1850, according to analyses released concurrently by Nasa and the National Oceanic and Atmospheric Administration (Noaa) on Friday, with a record high in ocean temperatures and a new low in Antarctic sea ice extent. Noaa calculated that last year's global temperature was 1.35C (2.4F) hotter, on average, than the pre-industrial era, which is slightly less than the 1.48C (2.6F) increase that EU scientists, who also found 2023 was the hottest on record, came up with due to slightly different methodologies.

A separate analysis of 2023 released on Friday by Berkeley Earth has the year at 1.54C above pre-industrial times, which is above the 1.5C (2.7F) warming limit that countries have agreed to keep to in order to avoid disastrous global heating impacts. This guardrail will need to be broken on a consistent basis, rather than one year, to be considered fully breached, however. The burning of fossil fuels and deforestation has driven the extraordinary warmth, which follows a string of hotter-than-average years in recent decades. Each decade over the past 40 years has been warmer than the last, Noaa said, with the most recent 10 years all making up the hottest 10 years ever recorded. Last year's record heat was further spurred by El Niño, a periodic climatic event that heats up parts of the Pacific Ocean and heightens global temperatures.

Beaver Ponds May Exacerbate Warming In Arctic, Scientists Say (theguardian.com) 95

An anonymous reader quotes a report from The Guardian: The stream through western Alaska never looked like this before. In aerial photography from the 1980s, it wove cleanly through the tundra, thin as thread. Today, in satellite images, it appears as a string of black patches: one large pond after another, dozens of meters apart. It's a transformation that is happening across the Arctic, the result of landscape engineering on an impressive scale. But this is no human endeavor to reshape the world. It is the work of the North American beaver, and there is no sign of it stopping. Were the waddling rodents making minor inroads, researchers may never have noticed. But the animals are pouring in, pushing north into new territories. The total number of animals is far from clear, but the ponds they create are hard to miss: in the Arctic tundra of Alaska alone, the number of beaver ponds on streams have doubled to at least 12,000 in the past 20 years. More lodges are dotted along lakes and river banks.

The preponderance of beavers, which can weigh as much as 45kg, follows a collapse in trapping and the warming of a landscape that once proved too bleak for occupation. Global heating has driven the shrubification of the Arctic tundra; the harsh winter is shorter, and there is more free-running water in the coldest months. Instead of felling trees for their dams, the beavers construct them from surrounding shrubs, creating deep ponds in which to build their lodges. The new arrivals cause plenty of disruption. For some communities, the rivers and streams are the roads of the landscape, and the dams make effective roadblocks. As the structures multiply, more land is flooded and there can be less fresh water for drinking downstream. But there are other, less visible effects too. The animals are participants in a feedback loop: climate change opens the landscape to beavers, whose ponds drive further warming, which attracts even more paddle-tailed comrades. Physics suggested this would happen. Beaver ponds are new bodies of water that cover bare permafrost. Because the water is warm -- relatively speaking -- it thaws the hard ground, which duly releases methane, one of the most potent greenhouse gases.

Scientists now have evidence this is happening. Armed with high-resolution satellite imagery, Tape and his colleagues located beaver ponds in the lower Noatak River basin area of north-western Alaska. They then analyzed infrared images captured by Nasa planes flying over the region. Overlaying the two revealed a clear link between beaver ponds and methane hotspots that extended for tens of meters around the ponds. "The transformation of these streams is a positive feedback that is accelerating the effects of climate change, and that is what's concerning," says Tape. "They are accelerating it at every one of these points." Because the Nasa images give only a snapshot in time, the researchers will head out next year to measure methane on the ground. With more measurements, they hope to understand how the emissions vary with the age of beaver ponds: do ponds release a steady flow of methane, or does the release wane after a decade or two?
"What's happening here is happening on a huge scale," says Ken Tape, an ecologist at the University of Alaska, Fairbanks, who is tracking the influx of beavers into the sparse northern landscape. "Our modeling work, which is in progress right now, shows that this entire area, the north slope of Alaska, will be colonized by beavers by 2100."

NASA Selects Bold Proposal To 'Swarm' Proxima Centauri With Tiny Probes (universetoday.com) 113

In order to reach places like Alpha Centauri this century, we'll need to utilize gram-scale spacecraft that rely on directed-energy propulsion. To that end, NASA has selected the Swarming Proxima Centauri project for Phase I development as part of this year's NASA Innovative Advanced Concepts (NIAC) program. According to Universe Today, Swarming Proxima Centauri is "a collaborative effort between Space Initiatives Inc. and the Initiative for Interstellar Studies (i4is) led by Space Initiative's chief scientist Marshall Eubanks." From the report: According to Eubanks, traveling through interstellar space is a question of distance, energy, and speed. At a distance of 4.25 light-years (40 trillion km; 25 trillion mi) from the Solar System, even Proxima Centauri is unfathomably far away. To put it in perspective, the record for the farthest distance ever traveled by a spacecraft goes to the Voyager 1 space probe, which is currently more than 24 billion km (15 billion mi) from Earth. Using conventional methods, the probe accomplished a maximum speed of 61,500 km/h (38,215 mph) and has been traveling for more than 46 years straight.

In short, traveling at anything less than relativistic speed (a fraction of the speed of light) will make interstellar transits incredibly long and entirely impractical. Given the energy requirements this calls for, anything other than small spacecraft with a maximum mass of a few grams is feasible. [...] In contrast, concepts like Breakthrough Starshot and the Proxima Swarm consist of "inverting the rocket" -- i.e., instead of throwing stuff out, stuff is thrown at the spacecraft. Instead of heavy propellant, which constitutes the majority of conventional rockets, the energy source for a lightsail is photons (which have no mass and move at the speed of light). But as Eubanks indicated, this does not overcome the issue of energy, making it even more important that the spacecraft be as small as possible. "Bouncing photons off of a laser sail thus solves the speed-of-stuff problem," he said. "But the trouble is, there is not much momentum in a photon, so we need a lot of them. And given the power we are likely to have available, even a couple of decades from now, the thrust will be weak, so the mass of the probes needs to be very small -- grams, not tons."

Their proposal calls for a 100-gigawatt (GW) laser beamer boosting thousands of gram-scale space probes with laser sails to relativistic speed (~10-20% of light). They also proposed a series of terrestrial light buckets measuring a square kilometer (0.386 mi2) in diameter to catch the light signals from the probes once they are well on their way to reaching Proxima Centauri (and communications become more difficult). By their estimates, this mission concept could be ready for development around midcentury and could reach Proxima Centauri and its Earth-like exoplanet (Proxima b) by the third quarter of this century (2075 or after). [...] Eubanks and his colleagues hope that the development of a coherent swarm of robotic probes will have applications closer to home. Swarm robotics is a hot field of research today and is being investigated as a possible means of exploring Europa's interior ocean, digging underground cities on Mars, assembling large structures in space, and providing extreme weather tracking from Earth's orbit. Beyond space exploration and Earth observation, swarm robotics also has applications in medicine, additive manufacturing, environmental studies, global positioning and navigation, search and rescue, and more.

Hubble Finds Weird Home of Farthest Fast Radio Burst (nasa.gov) 27

Astronomers using NASA's Hubble Space Telescope have found a rare event in an oddball place. NASA reports: It's called a fast radio burst (FRB), a fleeting blast of energy that can -- for a few milliseconds -- outshine an entire galaxy. Hundreds of FRBs have been detected over the past few years. They pop off all over the sky like camera flashes at a stadium event, but the sources behind these intense bursts of radiation remain uncertain. This new FRB is particularly weird because it erupted halfway across the universe, making it the farthest and most powerful example detected to date.

And if that's not strange enough, it just got weirder based on the follow-up Hubble observations made after its discovery. The FRB flashed in what seems like an unlikely place: a collection of galaxies that existed when the universe was only 5 billion years old. The large majority of previous FRBs have been found in isolated galaxies. FRB 20220610A was first detected on June 10, 2022, by the Australian Square Kilometer Array Pathfinder (ASKAP) radio telescope in Western Australia. The European Southern Observatory's Very Large Telescope in Chile confirmed that the FRB came from a distant place. The FRB was four times more energetic than closer FRBs.

"It required Hubble's keen sharpness and sensitivity to pinpoint exactly where the FRB came from," said lead author Alexa Gordon of Northwestern University in Evanston, Illinois. "Without Hubble's imaging, it would still remain a mystery as to whether this was originating from one monolithic galaxy or from some type of interacting system. It's these types of environments -- these weird ones -- that are driving us toward better understanding the mystery of FRBs." Hubble's crisp images suggest this FRB originated in an environment where there may be as many as seven galaxies on a possible path to merging, which would also be very significant, researchers say.

NASA Postpones Plans To Send Humans To Moon (theguardian.com) 71

NASA has postponed its plans to send humans to the moon after delays hit its hugely ambitious Artemis programme, which aims to get spaceboots bouncing again on the lunar surface for the first time in half a century. From a report: The US space agency has announced the Artemis III mission to land four astronauts near the lunar south pole will be delayed a year until September 2026. Artemis II, a 10-day expedition to send a crew around the moon and back to test life support systems, will also be pushed back to September 2025.

NASA said the delays would allow its teams to work through development challenges associated with the programme, which partners with private companies including Elon Musk's SpaceX and Lockheed Martin and uses some largely untested spacecraft and technology. "We are returning to the moon in a way we never have before, and the safety of our astronauts is Nasa's top priority as we prepare for future Artemis missions," said the Nasa administrator Bill Nelson. Washington wants to establish a long-term human presence outside Earth's orbit, including construction of a lunar base camp as well as a space station that circles the moon. Its ultimate plans are to send people to Mars, but it has decided to return to the moon first to learn more about deep space before embarking on what would be a months-long voyage to the red planet.

Whatever Happened to the Surviving Apollo Astronauts? (bbc.com) 48

The BBC checks in on "the pioneers of space exploration — the 24 Nasa astronauts who travelled to the Moon in the Apollo missions of the 1960s and 1970s." Ken Mattingly and Frank Borman died within a few days of each other late last year. Now only eight people who have voyaged beyond the Earth's orbit remain. Who are they, and what are their stories...? There are only four people still alive who have walked on the Moon — Charlie Duke is one of them. He did it aged 36, making him the youngest person to set foot on the lunar surface... Charlie Duke now lives outside San Antonio, Texas, with Dorothy, to whom he has been married for 60 years....

Jim Lovell is one of only three men to have travelled to the Moon twice, and following Frank Borman's death in November 2023, he became the oldest living astronaut....

After leaving Nasa in 1975, [Harrison Schmitt] was elected to the U.S. Senate from his home state of New Mexico, but only served one term. Since then he has worked as a consultant in various industries as well as continuing in academia.

And when confronted by a man claiming Apollo 11 was an elaborate lie, 72-year-old Buzz Aldrin "punched him on the jaw." Despite struggles in later life, he never lost his thirst for adventure and joined expeditions to both the North and South Poles, the latter at the age of 86. While embracing his celebrity, he has remained an advocate for the space programme, especially the need to explore Mars.

"I don't think we should just go there and come back — we did that with Apollo," he says.

Last 93-year-old Buzz Aldrin got married — and thanked his fans for remembering his birthday. "It means a lot and I hope to continue serving a greater cause for many more revolutions around the sun."

Neptune Is Much Less Blue Than Depictions (seattletimes.com) 38

Long-time Slashdot readers necro81 writes: The popular vision of Neptune is azure blue. This comes mostly from the publicly released images from Voyager 2's flyby in 1989 — humanity's only visit to this icy giant at the edge of the solar system. But it turns out that view is a bit distorted — the result of color-enhancing choices made by NASA at the time. A new report from Oxford depicts Neptune's blue color as more muted, with a touch of green, not much different than Uranus. The truer-to-life view comes from re-analyzing the Voyager data, combined with ground-based observations going back decades. (Add'l links here, here, and here.)

This is nothing new: most publicity images released by space agencies — of planets, nebulae, or the surface of Mars — have undergone some color-enhancement for visual effect. (They'll also release "true-color" images, which try to best mimic what the human eye would see.) Many images — such as those from the infrared-seeing JWST — need wholesale coloration of their otherwise invisible wavelengths. The new report is a good reminder, though, to remember that scientific cameras are pretty much always black and white; color images come from combining filters in various ways.

Navajo Nation Objects To Landing Human Remains On Moon, Prompting Last-Minute White House Meeting (cnn.com) 193

The White House has convened a last-minute meeting to discuss a private lunar mission, Peregrine Mission One, after the Navajo Nation requested a delay due to cultural concerns over the transport of human ashes for burial on the moon. "The moon holds a sacred place in Navajo cosmology," said Navajo Nation President Buu Nygren in a statement. "The suggestion of transforming it into a resting place for human remains is deeply disturbing and unacceptable to our people and many other tribal nations."

If successful, the commercial mission scheduled to launch Monday "will be the first time an American-made spacecraft has landed on the lunar surface since the end of the Apollo program in 1972," notes CNN. Longtime Slashdot reader garyisabusyguy shares the report: The private companies providing these lunar burial services, Celestis and Elysium Space, are just two of several paying customers hitching a ride to the moon on Pittsburgh-based Astrobotic Technology's Peregrine lunar lander. The uncrewed spacecraft is expected to lift off on the inaugural flight of the United Launch Alliance's Vulcan Centaur rocket from Florida's Cape Canaveral Space Force Station. Celestis' payload, called Tranquility Flight, includes 66 "memorial capsules" containing "cremated remains and DNA," which will remain on the lunar surface "as a permanent tribute to the intrepid souls who never stopped reaching for the stars," according to the company's website.

"We are aware of the concerns expressed by Mr. Nygren, but do not find them substantive," Celestis CEO Charles Chafer told CNN. "We reject the assertion that our memorial spaceflight mission desecrates the moon," Chafer said. "Just as permanent memorials for deceased are present all over planet Earth and not considered desecration, our memorial on the moon is handled with care and reverence, is a permanent monument that does not intentionally eject flight capsules on the moon. It is a touching and fitting celebration for our participants -- the exact opposite of desecration, it is a celebration." Elysium Space has not responded to CNN's request for a comment, but the company's website describes its "Lunar Memorial" as delivering "a symbolic portion of remains to the surface of the Moon, helping to create the quintessential commemoration." "I've been disappointed that this conversation came up so late in the game," John Thornton, Astrobotic Technology CEO, said. "I would have liked to have had this conversation a long time ago. We announced the first payload manifest of this nature to our mission back in 2015. A second in 2020. We really are trying to do the right thing and I hope we can find a good path forward with Navajo Nation." [...]

Friday's meeting convened by the White House is scheduled to feature representatives from NASA, the FAA, the US Department of Transportation, and the Department of Commerce. But Navajo Nation officials have little hope that they will be able to stop Monday's launch. "Based off of what we're seeing, and NASA are already having their pre-launch briefing, it doesn't look like they have any intention of stopping the launch or removing the remains," Ahasteen said.

New Images of Jupiter's Moon Io Capture Infernal Volcanic Landscape (nytimes.com) 16

NASA's Juno spacecraft made its closest flyby yet of Io, one of Jupiter's largest moons, sending back images of "sharp cliffs, edgy mountain peaks, lakes of pooled lava and even a volcanic plume," reports the New York Times. From the report: The Juno spacecraft, designed to study the origin and evolution of Jupiter, arrived at the planet in 2016. NASA extended the mission in 2021, and the orbiter has since captured photos of the Jovian moons Ganymede, Europa and most recently Io. [...] Juno conducted a number of more distant observations of Io in recent years. Its latest flyby occurred on Dec. 30, when the spacecraft came within 932 miles of the moon. The images captured during this visit were made with an instrument called JunoCam and are in visible wavelengths. They are some of the highest resolution views of Io's global structure. The mission's managers shared six images of Io on the mission's website, and members of the public have since uploaded digitally enhanced versions that highlight features on Io's surface.

Mission scientists are already at work analyzing these images, searching for differences across Io's surface to learn how often its volcanoes erupt, how bright and hot those eruptions are and how the resulting lava flows. According to Dr. Bolton, the team will also compare Juno's images to older views of the Jovian moon to determine what has changed on Io over a variety of encounters. And they'll get a second set of data to work with in a month, when Juno completes another close flyby of the explosive world on Feb. 3.

India To Study Black Holes With First Satellite Launch After US (bloomberg.com) 27

India launched its first satellite on Monday to study black holes as it seeks to deepen its space exploration efforts ahead of an ambitious crewed mission next year. From a report: The spacecraft, named X-ray Polarimeter Satellite, was propelled into an orbit of 350 kilometers from an island near India's main spaceport of Sriharikota, off the southern state of Andhra Pradesh, according to S. Somanath, chairman of the Indian Space Research Organisation. The satellite, weighing about 470 kilograms, will carry out research on X-rays emanating from around 50 celestial objects with the help of two payloads built by ISRO and a Bengaluru-based research institute.

NASA launched a similar mission, the Imaging X-ray Polarimetry Explorer, in 2021 to answer questions such as why black holes spin and build on the findings of its flagship telescope Chandra X-ray Observatory that blasted off more than two decades ago. China's National Space Administration launched the country's first X-ray space telescope to observe black holes, pulsars and gamma-ray bursts in 2017.

2023 Will Be Remembered as the Year Climate Change Arrived (msn.com) 159

This summer 80 million Americans were experiencing 105-degree heat. And tonight the Washington Post identifies what was unique about 2023's weather: "the heat's all-consuming relentlessness.

"It went day by day, continent by continent, until people all over the map, whether in the Amazon or the Pacific islands or rural Greece, had glimpsed a climate future for which they are not prepared..." Even if its extremes are ultimately eclipsed, as seems inevitable, 2023 will mark a point when humanity crossed into a new climate era — an age of "global boiling," as United Nations Secretary General António Guterres called it. The year included the hottest single day on record (July 6) and the hottest ever month (July), not to mention the hottest June, the hottest August, the hottest September, the hottest October, the hottest November, and probably the hottest December. It included a day, November 17, when global temperatures, for the first time ever, reached 2 degrees Celsius above the preindustrial levels.

Discomfort, destruction, and death are the legacy of those records.

In Phoenix, a heat wave went on for so long, with 31 consecutive days above 110 Fahrenheit, that one NASA atmospheric scientist called it "mind-boggling." The surrounding county recorded a record number of heat deaths, nearly 600. In Brazil, drought sapped the normally lush Amazon, causing towns to ration drinking water, contributing to the deaths of endangered pink dolphins, and choking off the river-based system of travel and commerce... At one point the coastal Florida Keys waters reached 100 degrees, comparable to a hot tub...

One explanation for 2023's extreme heat is El Niño — a recurring oceanic phenomenon that warms the waters in the Pacific and causes a global ripple of consequences. But the scale of this year's heat — amplified by human-caused factors and the burning of fossil fuels — is still well beyond what most scientists had thought possible. Some have theorized that planetary warming may be accelerating. Others have said there's not enough evidence. What they agree upon, though, is that the earth is trending toward more extreme heat. That means that the experiences of 2023 can seem astonishing in the short-term but will one day look tame.

This year, then, will wind up as the first — and almost surely not the last — in which temperatures were at or near 1.5 Celsius above preindustrial levels, a threshold the Paris agreement has aimed to avoid.

The article includes two more sobering statistics:
  • "The University of Maine's Climate Change Institute logs daily global temperatures going back to 1940. From this July on, almost without fail, every daily temperature in 2023 topped the daily temperature from the same date in any of the prior 83 years."
  • "In Brazil, the Rio Negro, one of the Amazon's main tributaries, fell to its lowest level since record keeping began more than a century earlier."

Navajo Nation President Asks NASA to Delay Moon Launch Over Possible Human Remains (knau.org) 203

"Navajo Nation President Buu Nygren has asked NASA to delay a scheduled launch to the Moon that could include cremated remains," reports Arizona Public Radio station KNAU: Nygren says he recently learned of the January 8 launch of the Vulcan Centaur carrying the Peregrine Mission One. The lander will carry some payloads from a company known to provide memorial services by shipping human cremated remains to the Moon. Nygren wants the launch delayed and the tribe consulted immediately. He noted the Moon is sacred to numerous Indigenous cultures and that depositing human remains on it is "tantamount to desecration."

NASA previously came under fire after the ashes of former geologist and planetary scientist Eugene Shoemaker were sent to the Moon in 1998. Then-Navajo Nation President Albert Hale said the action was a gross insensitivity to the beliefs of many Native Americans. NASA later apologized and promised to consult with tribes before authorizing any similar missions in the future.

Could We Build a Concert Venue in Space? (washingtonpost.com) 75

What would happen if we built a concert venue in near-Earth orbit? A science policy journalist explores the question in the Washington Post: Forget U2 in the Las Vegas Sphere. Take me to a real concert in the round, where I can float 360 degrees around the stage, watching a guitarist shred from the perspective of a fly and inventing dance moves that Earth's gravity would forbid.

Before you dismiss this as a hallucination, consider that we're on the cusp of a new era of space travel. Engineer and space architect Ariel Ekblaw, founder of MIT's Space Exploration Initiative, says that within a decade, a trip off the planet could become as accessible as a first-class airline ticket — and that, in 15 or 20 years, we can expect space hotels in near-Earth orbit. She's betting on it, having founded a nonprofit to design spherical, modular habitats that can assemble themselves in space so as to be lightweight and compact at launch, much like the James Webb Space Telescope that NASA vaulted into deep space two years ago.

"The first era of space travel was about survival," she told me as I recently toured her lab. "We're transitioning now to build spaces that are friendlier and more welcoming so that people can thrive in space as opposed to just survive." There's no reason, Ekblaw said, that a concert hall can't be one of those structures.

The article ultimately calls this "an impulse for space travel I can get behind: curiosity about who we are and what more we can create when we reach beyond Earth. This is the realm of not just scientists and engineers but of all kinds of dreamers. It's a rendition of space exploration that can engage anyone to imagine what's possible."

'Behold - the Best Space Images of 2023' (scientificamerican.com) 5

As the year comes to a close, "one constant, reliable source of awe and beauty is the sky over our head..." writes astronomer Phil Plait in Scientific America

"And every year we see new things, or old things in new ways, and I've been set the wonderful task of selecting my favorites and relaying them and their import to you." End-of-year lists, especially those displaying astronomical imagery, tend to be splashy and colorful. That's understandable, but what they sometimes miss are the more subtle photographs, those that hide momentous discoveries in minor visual details or offer fresh perspectives on familiar objects. They may not leap off the page, but they still have an impact. That's what I've kept in mind while sorting through this year's celestial treasure trove. This gallery is by no means complete, but it shows what I think are some of the most interesting astronomical portraits to have emerged in 2023.

No gallery such as this would be complete without something from the James Webb Space Telescope (JWST), our newest infrared eye on the sky. This monster observatory has already brought so many small revolutions to astronomy that picking one from the past year is no small task. Should it be a baby star throwing an immense tantrum or a massive old star shedding material at colossal rates before it inevitably explodes as a supernova? Or should it be a map of a mind-stomping 100,000 galaxies?

Well, how about something very, very different — such as the skeletal structure of a nearby galaxy's intricate web of dust [also displayed at the top of Scientiic American's article]...? [I]t has a beautiful spiral structure and shows the effects of a smaller galaxy colliding with it. In the phenomenally sharp and decidedly eerie false-color view from JWST's Mid-Infrared Instrument, we see countless clouds of cosmic dust in a skeletonlike pattern. Each of these clouds is made up of small grains of rocky and sooty carbon-based molecules expelled by dying stars...

Astronomers captured this image to better understand how stars are born in stellar nurseries and how they evolve over time.

SpaceX Wows With a Double Header of Final 2023 Rocket Launches (space.com) 43

SpaceX on Thursday launched two rockets into orbit, only three hours apart, bringing its total number of launches to 98 in 2023. Space.com reports: The first SpaceX mission to take to the skies Thursday (Dec. 28) was a Falcon Heavy rocket carrying the U.S. military's secretive X-37B space plane, designed mission USSF-52. That blasted off from NASA's Kennedy Space Center in Florida at 8:07 p.m. EST (0107 GMT on Dec. 29). This marked the second Falcon Heavy flight of 2023. Second up on the launch docket for Thursday, hours later, was a Falcon 9 liftoff carrying 23 SpaceX Starlink units to low Earth orbit from nearby Cape Canaveral Space Force Station. This launch took place at 11:01 p.m. EST (0401 GMT on Dec. 29). This was SpaceX's 98th and final launch of 2023, and the 96th flight for a Falcon 9 rocket this year.

SpaceX's 97th launch overall for this year marked the seventh flight for X-37B, but the first time the space plane hitched a lift atop a Falcon Heavy rocket. The X-37B/Falcon Heavy launch had been scrubbed several times previously due to bad weather and an issue with ground equipment. The launch of 23 Starlink broadband satellites from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida that capped off 2023 was also the 96th launch of a Falcon 9 rocket during this year. SpaceX's next launch is targeted for Jan. 2, 2024 and will see a further 21 Starlink satellites lift to orbit to join the over 5,500 internet supplying units currently orbiting Earth.

Reckless DMCA Deindexing Pushes NASA's Artemis Towards Black Hole (torrentfreak.com) 83

Andy Maxwell reports via TorrentFreak: As the crew of Artemis 2 prepare to become the first humans to fly to the moon since 1972, the possibilities of space travel are once again igniting imaginations globally. More than 92% of internet users who want to learn more about this historic mission and the program in general are statistically likely to use Google search. Behind the scenes, however, the ability to find relevant content is under attack. Blundering DMCA takedown notices sent by a company calling itself DMCA Piracy Prevention Inc. claim to protect the rights of an OnlyFans/Instagram model working under the name 'Artemis'. Instead, keyword-based systems that fail to discriminate between copyright-infringing content and that referencing the word Artemis in any other context, are flooding towards Google. They contain demands to completely deindex non-infringing, unrelated content, produced by innocent third parties all over the world.

A recent deindexing demand dated December 13, 2022, lists DMCA Piracy Prevention Inc. of Canada as the sender. The name of the content owner is redacted but the notice itself states that the company represents a content creator performing under the name Artemis. The notice demands the removal of 3,617 URLs from Google search. If successful, those URLs would be completely unfindable by more than 92% of the world's population who use that search engine. [...] At least 9 of the first 20 URLs in the notice demand the removal of non-infringing articles and news reports referencing the Artemis space program. None have anything to do with the content the sender claims to protect. [...]

Theories as to who might own and/or operate DMCA Piracy Prevention Inc. aren't hard to find but the company does exist and is registered as a corporate entity in Canada. Registered at the same address is a company with remarkably similar details. BranditScan is a corporate entity operating in exactly the same market offering similar if not identical services. BranditScan has sent DMCA takedown notices to Google under three different notifier accounts.
