NASA’s Orion capsule made a blisteringly fast return from the Moon Sunday, parachuting into the Pacific off Mexico to conclude a test flight that should clear the way for astronauts on the next lunar flyby.

The incoming capsule hit the atmosphere at Mach 32, or 32 times the speed of sound, and endured reentry temperatures of 5,000 degrees Fahrenheit (2,760 degrees Celsius) before splashing down west of Baja California near Guadalupe Island. A Navy ship quickly moved in to recover the spacecraft and its silent occupants — three test dummies rigged with vibration sensors and radiation monitors.

NASA hailed the descent and splashdown as close to perfect, as congratulations poured in from Washington..

“I’m overwhelmed,” NASA Administrator Bill Nelson said from Mission Control in Houston. “This is an extraordinary day… It’s historic because we are now going back into space — deep space — with a new generation.”

The space agency needed a successful splashdown to stay on track for the next Orion flight around the Moon, targeted for 2024 with four astronauts who will be revealed early next year. That would be followed by a two-person lunar landing as early as 2025 and, ultimately, a sustainable Moon base. The long-term plan would be to launch a Mars expedition by the late 2030s.

Astronauts last landed on the Moon 50 years ago. After touching down on December 11, 1972, Apollo 17′s Eugene Cernan and Harrison Schmitt spent three days exploring the valley of Taurus-Littrow, the longest stay of the Apollo era. They were the last of the 12 Moonwalkers.

Orion was the first capsule to visit the Moon since then, launching on NASA’s new mega Moon rocket from Kennedy Space Center on November 16. It was the first flight of NASA’s new Artemis Moon program, named after Apollo’s mythological twin sister.

“From Tranquility Base to Taurus-Littrow to the tranquil waters of the Pacific, the latest chapter of NASA’s journey to the Moon comes to a close. Orion back on Earth,” announced Mission Control commentator Rob Navias.

While no one was on the $4 billion test flight, NASA managers were thrilled to pull off the dress rehearsal, especially after so many years of flight delays and busted budgets. Fuel leaks and hurricanes conspired for additional postponements in late summer and fall.

In an Apollo throwback, NASA held a splashdown party at Houston’s Johnson Space Center on Sunday, with employees and their families gathering to watch the broadcast of Orion’s homecoming. Next door, the visitor center threw a bash for the public.

Getting Orion back intact after the 25-day flight was NASA’s top objective. With a return speed of 25,000 mph (40,000 kph) — considerably faster than coming in from low-Earth orbit — the capsule used a new, advanced heat shield never tested before in spaceflight. To reduce the gravity or G loads, it dipped into the atmosphere and briefly skipped out, also helping to pinpoint the splashdown area.

All that unfolded in spectacular fashion, officials noted, allowing for Orion’s safe return.

“I don’t think any one of us could have imagined a mission this successful,” said mission manager Mike Sarafin.

Further inspections will be conducted once Orion is back at Kennedy by month’s end. If the capsule checks find nothing amiss, NASA will announce the first lunar crew amid considerable hoopla in early 2023, picking from among the 42 active U.S. astronauts stationed at Houston’s Johnson Space Center.

“People are anxious, we know that,” Vanessa Wyche, Johnson’s director, told reporters. Added Nelson: “The American people, just like (with) the original seven astronauts in the Mercury days, are going to want to know about these astronauts.”

The capsule splashed down more than 300 miles (482 kilometers) south of the original target zone. Forecasts calling for choppy seas and high wind off the Southern California coast prompted NASA to switch the location.

Orion logged 1.4 million miles (2.25 million kilometers) as it zoomed to the Moon and then entered a wide, swooping orbit for nearly a week before heading home.

It came within 80 miles (130 kilometers) of the Moon twice. At its farthest, the capsule was more than 268,000 miles (430,000 kilometers) from Earth.

Orion beamed back stunning photos of not only the gray, pitted Moon, but also the home planet. As a parting shot, the capsule revealed a crescent Earth — Earthrise — that left the mission team speechless.

Nottingham Trent University astronomer Daniel Brown said the flight’s many accomplishments illustrate NASA’s capability to put astronauts on the next Artemis Moonshot.

“This was the nail-biting end of an amazing and important journey for NASA’s Orion spacecraft,” Brown said in a statement from England.

The Moon has never been hotter. Just hours earlier Sunday, a spacecraft rocketed toward the Moon from Cape Canaveral. The lunar lander belongs to ispace, a Tokyo company intent on developing an economy up there. Two U.S. companies, meanwhile, have lunar landers launching early next year.

Scientists Recreate Cosmic Ray Physics Using Cold Atom in New Laboratory Study

For the first time, researchers have managed to simulate a fundamental process of cosmic particle acceleration in a laboratory: the first series of discoveries that will transform our understanding of cosmic rays. Now, scientists from the Universities of Birmingham and Chicago have created a tiny, 100-micrometre Fermi accelerator, in which mobile optical potential barriers collide with trapped atoms, in a partial replica of how cosmic particles pick up energy in space. The technique not only replicates cosmic ray behaviour but also sets a new benchmark in quantum acceleration technology.

Lab-Built Fermi Accelerator Using Cold Atoms Validates Cosmic Ray Theory and Advances Quantum Tech

As per findings published in Physical Review Letters, this fully controllable setup demonstrated particle acceleration through the Fermi mechanism first proposed by physicist Enrico Fermi in 1949. Long theorised to underlie cosmic ray generation, the process had never been reliably replicated in a lab. By combining energy gains with particle losses, researchers created energy spectra similar to those observed in space, offering the first direct validation of Bell’s result, a cornerstone of cosmic ray physics.

In Fermi acceleration, ultracold atoms are accelerated to more than 0.5 metres per second using laser-controlled barriers. Dr Amita Deb, a coauthor and researcher at the University of Birmingham, mentioned, ‘Our chimney is more powerful than conventional quantum nano-measurements, which are the best acceleration tools in the world so far, and while its simplicity and small size can be compelling, its lack of a theoretical speed limit is the most attractive feature.’ The ultracold atomic jets could be readily controlled with high precision in the subsequent experiments.

This progress means that, for the first time, complicated astrophysical events like shocks and turbulence can be studied in a laboratory, lead author Dr Vera Guarrera stated. This opens new avenues for high-energy astrophysics and also for applications in quantum wavepacket control and quantum chemistry.

Researchers plan to find out how different behaviour affects energy cutoffs and acceleration rates. A compact Fermi accelerator of this type could be a cornerstone for studies of fundamental physics and also connect to emerging technologies such as atomtronics.

Scientists Say Dark Matter Could Turn Failed Stars Into ‘Dark Dwarfs’

Astronomers now propose that “failed stars” known as brown dwarfs could be powered by dark matter. Dark matter makes up about 85 percent of the universe’s matter but does not shine; it interacts only via gravity. Brown dwarfs form like stars but lack enough mass to ignite fusion. The theory suggests brown dwarfs in galaxy centers might trap dark matter in their interiors. When that dark matter annihilates, it releases energy that heats the star, turning the dwarf into a brighter “dark dwarf.” If such objects exist, finding them would give scientists a new clue to the nature of dark matter.

Dark Matter in Failed Stars

According to the new model, dense brown dwarfs at the centers of galaxies act like gravity wells that accumulate dark matter. Because dark matter interacts only via gravity, it naturally drifts to galactic cores, where it can be captured by star. As University of Hawai‘i physicist Jeremy Sakstein explains, once inside a star dark matter can annihilate with itself, releasing energy that heats the dwarf. The more dark matter a brown dwarf collects, the more energy it outputs. Crucially, this effect only works if dark matter particles self-annihilate (as with heavy WIMPs); lighter or non-interacting candidates like axions would not create dark dwarfs.

They propose using a chemical signature: a dark dwarf should hold on to lithium-7 that normal brown dwarfs burn away. The researchers say powerful telescopes like NASA’s James Webb Space Telescope might already be sensitive enough to spot cool, dim dark dwarfs near the Milky Way’s center. Detecting even one would strongly suggest that dark matter is made of heavy, self-interacting particles (like WIMPs).

In related work, Colgate astrophysicist Jillian Paulin coauthored studies of ancient “dark stars” fueled by dark matter, while SLAC physicist Rebecca Leane and collaborators have shown that dark matter capture could heat brown dwarfs and exoplanets – a process called “dark kinetic heating”. Together, these ideas highlight how even dim, unusual stars could illuminate the nature of dark matter.

New Gel-Based Robotic Skin Feels Touch, Heat, and Damage Like Human Flesh

Researchers have created a novel electronic “skin” that could let robots experience a sense of touch. This low-cost, gelatin-based material is highly flexible and durable and can be molded over a robot hand. Equipped with electrodes, the skin detects pressure, temperature changes, and even sharp damage. In tests it responded to pokes, burns and cuts. Unlike conventional designs that use separate sensors for each stimulus, this single “multi-modal” material simplifies the hardware while providing rich tactile data. The findings, published in Science Robotics, suggest it could be used on humanoid robots or prosthetic limbs to give them a more human-like touch.

Multi-Modal Touch and Heat Sensing

According to the paper, unlike typical robotic skins, which require multiple specialized sensors, the new gel acts as a single multi-modal sensor. Its uniform conductive layer responds differently to a light touch, a temperature change or even a scratch by altering tiny electrical pathways. This design makes the skin simpler and more robust: researchers note it’s easier to fabricate and far less costly than conventional multi-sensor skins. In effect, one stretchy sheet of this material can replace many parts, cutting complexity while maintaining rich sensory feedback.

Testing the Skin and Future Applications

The research team tested the skin by casting the gel into a human-hand shape and outfitting it with electrodes. They put it through a gauntlet of trials: blasting it with a heat gun, pressing it with fingers and a robotic arm, and even slicing it open with a scalpel. Those harsh tests generated over 1.7 million data points from 860,000 tiny conductive channels, which fed into a machine-learning model so the skin could learn to distinguish different types of touch.

UCL’s Dr. Thomas George Thuruthel, a co-author of the study, said the robotic skin isn’t yet as sensitive as human skin but “may be better than anything else out there at the moment.” He noted that the material’s flexibility and ease of manufacture as key advantages. Moreover, the team believes this technology could ultimately help make robots and prosthetic devices with a more lifelike sense of touch.
