Juno Flyby of Ganymede and Jupiter

 

What would it be like to fly over the largest moon in the Solar System? In 2021, the robotic Juno spacecraft flew past Jupiter's huge moon Ganymede and took images that have been digitally constructed into a detailed flyby. As the featured video begins, Juno swoops over the two-toned surface of the 2,000-km wide moon, revealing an icy alien landscape filled with grooves and craters. The grooves are likely caused by shifting surface plates, while the craters are caused by violent impacts. Continuing on in its orbit, Juno then performed its 34th close pass over Jupiter's clouds. The digitally-constructed video shows numerous swirling clouds in the north, colorful planet-circling zones and bands across the middle – featuring several white-oval clouds from the String of Pearls, and finally more swirling clouds in the south.

3I/ATLAS Still Shows an Anti-Tail, as it Gets Closer to Earth

December 4, 2025

 

As of today, December 14, 2025, the interstellar object 3I/ATLAS is at a distance of about 270.5 million kilometers from Earth.

Its images are delayed by a quarter of an hour, as it takes light from 3I/ATLAS 15 minutes to reach us. On December 19, 2025, 3I/ATLAS will get closest to Earth at a perigee distance of 269.9097 (+/-0.0060) million kilometers.

 

The latest image of 3I/ATLAS was taken by Teerasak Thaluang on December 13, 2025 at 21:30:26 UTC with a 0.26-meter telescope in Rayong, Thailand (as reported here).

The rotational-gradient brightness map shows a prominent anti-tail, uncommon for comets, pointing in the direction of the Sun.

 

Whereas an anti-tail had been seen for solar system comets as a temporary perspective effect when the Earth crossed the comets’ orbital plane, this is clearly not the case with 3I/ATLAS.

The anti-tail was apparent in the first Hubble Space Telescope image, taken on July 21, 2025, when 3I/ATLAS was approaching the Sun from a geocentric distance of 2.98 times the Earth-Sun separation (AU) — as reported here and analyzed here, and was also apparent in the second Hubble image taken on November 30, 2025, when 3I/ATLAS was receding away from the Sun at a distance of 1.91 AU from Earth — as reported here.

The anti-tail was also apparent in thousands of images taken in between these dates.

 

The anti-tail of 3I/ATLAS is therefore not a perspective effect. It is a real physical jet, with a glow extending from 3I/ATLAS towards the Sun.

Its nature is a mystery because gas and micrometer-dust particles are expected to be pushed away from the Sun by solar radiation pressure and the solar wind, creating the appearance of a tail — as routinely seen in solar-system comets.

There was no mention of this mystery at the NASA press conference about 3I/ATLAS on November 19, 2025 (accessible here).

 

To explain the physics of the anti-tail of 3I/ATLAS, I have written three scientific papers.

The first two of these peer-reviewed papers, co-authored with Eric Keto (accessible here and here), associate the anti-tail with scattering of sunlight by fragments of ice shed from the sun-facing side of 3I/ATLAS.

These tiny ice particles evaporate before they get pushed back significantly by the solar radiation pressure and so they never appear as a conventional cometary tail.

The third (single-authored) paper, published on December 8, 2025 here, associates the anti-tail with a swarm of objects that lag behind 3I/ATLAS because of its non-gravitational acceleration away from the Sun (as reported by JPL Horizons here).

Analysis of the latest Hubble image could potentially favor one of these explanations.

 

By recognizing anomalies, we can learn something new. By ignoring them, we remain ignorant.

Isaacman has a second chance to make NASA great again

12/14/25 10:00 AM ET

 

The Senate Commerce Committee has confirmed billionaire entrepreneur and private space traveler Jared Isaacman to be NASA administrator. Isaacman has good hopes of being confirmed by the full Senate before the end of 2025.

Isaacman’s second confirmation hearing before the Senate Commerce Committee was a triumph. Sen. Ed Markey (D-Mass.) did try a series of gotcha questions about Elon Musk. Isaacman fended them off masterfully.

Most of the questioning was professional and, on the whole, friendly.

 

Sen. Andy Kim, (D-N.J.) had a back and forth with Isaacman about the so-called “Project Athena,” a plan for reforming NASA that Isaacman had developed during his first nomination process. He stood by the document but noted that it was a work in progress.

Both Markey and Kim ultimately voted no on Isaacman’s nomination. The final vote was 18 ayes, including all of the Republicans and three Democrats, and 10 nays, all Democrats.

 

Athena is not only a list of possible future projects for NASA, but a blueprint for how the space agency will operate in a world dominated by heavy-hitting commercial space companies such as SpaceX and Blue Origin.

It proposes three main goals for NASA in the 21st century: to lead the world in human space exploration, ignite a thriving space economy and become a force-multiplier for science

NASA would be reorganized to meet those goals.

 

The main theme of the hearing was that of competition — between companies for NASA projects, between profit-making enterprises in space and between countries for domination of space.

Isaacman, who said he “absolutely agrees with competition” offered a mic drop statement: “I think competition among world powers is actually a really good thing … just as long as we don’t lose.”

 

If approved, Isaacman’s main mandate, informed by Athena and the dictates of his political masters in Congress and the White House, is to get America back on the moon before the Chinese and to establish a lunar base.

He also means to spur NASA on to create new technologies — especially nuclear power and the propulsion necessary to expand human civilization beyond Earth.

 

If confirmed, Isaacman will also manage the transition from the International Space Station to commercial space platforms.

Finally, the new NASA administrator will have to preserve and reform the space agency’s science programs, currently under budget pressure from the Trump administration.

 

The moon would occupy much of Isaacman’s attention during the early part of his tenure at NASA.

The first thing he would have to oversee is the Artemis II mission, which will see a crew of four astronauts fly around the moon faster and farther than any humans since the Apollo 17 mission of 53 years ago.

Success of the mission will put the wind at the back of Artemis. Failure is not only not an option, but unthinkable for its potential for human tragedy and the destruction of America’s hope to win the second race to the moon.

 

Isaacman’s second task would be to make sure America wins that second race.

Some, such as former NASA Administrator Jim Bridenstine, have suggested that China is likely to beat America back to the moon. Isaacman has promised the Senate, Trump and the world that he will not allow that to happen. It is a heavy promise.

His third task would be to establish a permanent base on the moon and to fulfill all of the rest of the promises of Project Athena.

 

The sad fact of the matter is that because of Trump’s sudden withdrawal of Isaacman’s first nomination, NASA has wasted six months during which it has been almost leaderless.

The situation is unfortunate, to put the matter mildly, and could have been easily avoided given more sober leadership from the White House.

 

Still, if confirmed, Isaacman would assume control of a NASA buttressed with an unprecedented amount of good will.

He enjoys recommendations from politicians including Trump, former astronauts, Bridenstine and former NASA Deputy Administrator Lori Garver (talk about bipartisanship!), as well as movers and shakers from commercial space and the scientific community.

By experience and temperament, Isaacman has all the right stuff to be able to summon the future of a human civilization that has spread from just one planet to the moon, Mars and beyond.

U.S. Air Force Test Pilot School instructor Maj. Ross Elder to command NASA CHAPEA Mars mission

December 13, 2025

 

The long-standing link between the Air Force Test Pilot School and the United States space programme continues with the appointment of Maj. Ross Elder to lead a NASA Mars mission.

The school, formally established in 1944, has produced numerous astronauts and space researchers over the past 80 years.

 

Elder will command an all-volunteer crew in the next phase of NASA’s Crew Health and Performance Exploration Analog mission, known as CHAPEA.

The mission will study human performance during long-duration exploration by having four crew members live for more than a year inside the Mars Dune Alpha habitat at Johnson Space Center in Houston.

 

A native of Williamstown, West Virginia, Elder built his career through academic and operational aviation roles, including degrees in astronomical and mechanical engineering and extensive flying as an Air Force pilot.

After graduating from the Test Pilot School as part of class 20-B, he flew nearly 20 aircraft types and later served as an instructor at the school.

 

Following years of testing aircraft such as the F-15EX Eagle II, F-35 Lightning II and the XQ-58 Valkyrie, Elder transitioned to NASA and relocated to Johnson Space Center.

“To switch roles after testing for so long and becoming the subject being observed is a cool, but new, feeling. Entering that habitat for the first time was surreal when you realize this space is your future home,” Elder said.

 

Elder said the CHAPEA mission shares strong similarities with test pilot work, particularly in preparing for unexpected situations with limited support.

“In the test community we strive to be comfortable in uncomfortable situations, and this next assignment is no different,” he said.

“My primary concern is going to be ensuring our extremely talented crew members have everything they need to be successful in this journey.”

 

He also highlighted the challenge posed by communication delays between Earth and Mars, which can take up to 45 minutes for a single exchange.

Reflecting on the broader aerospace field, Elder said, “Aerospace as a whole is only going to continue to converge into a single multi-domain process.”

 

The Air Force Test Pilot School has expanded its focus on space through new courses and facilities, including a dedicated Space Test Course and satellite operations centre.

“I am absolutely humbled to be selected for this mission,” Elder said. “There will never be a single giant leap to Mars, but it’s a combination of everything that happens from the Edwards lakebed to the atmosphere above that will ultimately position humans as an interplanetary species.”

 

Elder is the first Test Pilot School instructor selected to lead a NASA mission and joins fellow graduates Maj. Adam Fuhrmann and Maj. Cameron Jones, who were also chosen as astronauts for future missions.

Their selection reflects the school’s continuing role in preparing personnel for advanced aerospace and space exploration challenges.

Strange, 7-hour explosion from deep space is unlike anything scientists have seen — Space photo of the week

December 14, 2025

 

A gamma-ray burst (GRB) — the most energetic type of explosion in the universe since the Big Bang — is detected once every day, on average.

But what happened on July 2, 2025, was highly unusual: NASA's Fermi Gamma-ray Space Telescope, which has been orbiting Earth since 2008, recorded an unusually long-lived GRB that continued emitting in bursts for more than seven hours.

 

Astronomers leaped into action, using the world's telescopes to detect the explosion's afterglow and discover where it came from. The event, called GRB 250702B, was the longest-duration gamma-ray burst ever recorded.

Astronomers now think it came from a previously unobserved or rare type of explosion that launched a narrow jet of material in the direction of the solar system, traveling at least 99% the speed of light.

 

GRB 250702B was not easy to figure out. Researchers used all kinds of telescopes to track its origin in all wavelengths of light, including the twin 8.1-meter Gemini telescopes in Chile and Hawaii, the Very Large Telescope in Chile, the Keck Observatory in Hawaii, and the Hubble Space Telescope.

GRBs come from the depths of the universe; even the closest one originated more than 100 million light-years away, according to NASA. GRB 250702B came from a massive galaxy 8 billion light-years distant that, critically, is so dusty that it blocked all visible light.

 

The only light detected by telescopes was infrared and high-energy X-ray wavelengths. Due to thick dust in its host galaxy, the GRB was almost invisible in ordinary visible light, the researchers reported in a study published Nov. 26 in The Astrophysical Journal Letters.

"This was the longest gamma-ray burst that humans have observed — long enough that it does not fit into any of our existing models for what causes gamma-ray bursts," Jonathan Carney, lead author of the study and doctoral student in physics and astronomy at the University of North Carolina at Chapel Hill, said in a statement.

 

Analysis shows that GRB 250702B may have been caused by the death of a massive star, a star being ripped apart by a black hole, or the merger of a helium star and a black hole, where the black hole spirals into the core of the massive star, triggering an explosion from within.

"But we can't yet tell which explanation is correct," Carney said. "In the future, this event will serve as a unique benchmark — when astronomers discover similar explosions, they'll ask whether they match GRB 250702B's properties or represent something different entirely."

China launches carrier rocket to deploy experimental cargo ship and satellite

Dec 14, 2025

 

China launched a Kuaizhou 11 carrier rocket on Saturday morning to deploy a privately developed experimental cargo ship and a satellite into space.

The rocket blasted off at 9:08 am at the Jiuquan Space Launch Center in the Inner Mongolia autonomous region and soon placed the DEAR 5 ship and the Xiwang 5B satellite into their preset orbital position, according to China Aerospace Science and Industry Corp, a State-owned space contractor that builds the Kuaizhou series rockets.

 

Developed by Beijing-based private spacecraft company AZSpace, the DEAR 5 is the second member of the company's B300-L family.

It consists of two major components - a service cabin and a payload capsule, and has 1.8 cubic meters available for up to 300 kilograms of payload.

According to the company, DEAR stands for Discovery, Exploration, Advance and Reentry.

 

Flying in an orbit 343 kilometers above the Earth, the robotic ship is carrying 34 sets of devices from research bodies, universities, and enterprises to conduct experiments related to microgravity physics, life and medical sciences, material science, and new space technologies, AZSpace said, noting it is designed to work at least one year in orbit.

In addition to the experimental payloads, the DEAR 5 also accommodates several "mini space labs" that can be used for experiments and educational purposes.

 

Zhang Xiaomin, chairman of AZSpace, said that an increasing number of research institutions and enterprises are looking to conduct scientific research in space.

"Our spacecraft is capable of meeting these needs. It aims to serve as a space laboratory for scientists, an orbital factory for entrepreneurs, and a 'delivery courier' for the space station," he said.

US Postal Service returns to deep space for 2026 Priority Mail stamps

December 13, 2025

 

Given its latest pair of stamps revealed for the new year, maybe the U.S. Postal Service should consider relabeling its expedited deliveries as "interstellar."

For the third year in a row, Priority Mail stamps in 2026 will feature images of the universe as captured by orbiting observatories.

The Priority Mail and Priority Mail Express postage depict views of the Crab Nebula and a galaxy pair, respectively.

 

"[These] new Priority Mail [and] Priority Mail Express stamps celebrate America's continued exploration of deep space with breathtaking images captured by NASA's James Webb Space Telescope," the USPS revealed on Friday (Dec. 12).

Domestic Priority Mail packages are delivered within one to three business days, according to the postal service.

By comparison, the vision of the Crab Nebula on the 2026 Priority Mail postage stamp took 6,500 light years to reach Earth and has been available for use since 2023 when NASA originally released the image.

 

"Webb's sensitivity and spatial resolution allow us to accurately determine the composition of the ejected material, particularly the content of iron and nickel, which may reveal what type of explosion produced the Crab Nebula," said Tea Temim at Princeton University, who led the team that used the telescope's Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI) to learn more about the nebula's origins.

In the infrared observation, what NASA describes as a "crisp, cage-like structure of fluffy gaseous filaments" is rendered in a red-orange hue.

In the central regions of the nebula, yellow-white and green emissions from dust grains were mapped out by Webb for the first time.

 

Priority Mail Express is the USPS's fastest service, offering one to three day delivery (including Sundays and holidays), which may explain why two galaxies "passing in the night" was chosen for the rate's 2026 postage stamp.

A composite, which uses the mid-infrared light from Webb and the visible and ultraviolet light from the Hubble Space Telescope, the "Galaxy Pair" depicts the smaller spiral IC 2163 passing behind NGC 2207, the spiral galaxy at right, millions of years ago.

 

Looking even more closely at the vista, bright red lines may indicate where material from the two galaxies may have slammed together. The scene, which NASA featured online in 2024, is located some 80 million light years from Earth.

Greg Breeding, an art director for the USPS, selected the NASA photos for the new issues, as he did for the 2024 ("Pillars of Creation" and "Cosmic Cliffs") and 2025 ("Spiral Galaxy" and "Star Cluster") stamps. The Webb was also the subject of a 2022 Forever denomination stamp that featured an artist's rendering of the deployed observatory in deep space.

 

A release date for the two 2026 stamps is pending the approval of the Postal Regulatory Commission of new Priority Mail and Priority Mail Express Flat Rate Envelope rates.

The change, as proposed by the USPS, would raise prices by about 6.6 percent for Priority Mail and 5.1 percent for Priority Mail Express, up from the 2025 prices of $10.10 and $31.40 per postage stamp, respectively.

Rocket Lab launches Japanese technology-demonstrating satellite to orbit

December 14, 2025

 

Rocket Lab launched a Japanese technology-demonstrating satellite on Saturday night (Dec. 13).

A 59-foot-tall (18 meters) Electron rocket launched the "RAISE and Shine" mission from Rocket Lab's New Zealand site on Saturday at 10:09 p.m. EST (0309 GMT and 4:09 p.m. local New Zealand time on Sunday, Dec. 14).

 

That was a delay of seven days; Rocket Lab originally targeted the night of Dec. 6 but pushed things back to allow time for additional checkouts.

"RAISE and Shine" is the first flight that Rocket Lab has contracted directly with JAXA (the Japan Aerospace Exploration Agency). It's part of a two-flight deal with the Japanese space agency; the second mission is a rideshare launch scheduled for early next year.

 

The California-based company has a long history with Japan overall, however, launching more than 20 missions to date for companies based in the Land of the Rising Sun.

Saturday's launch sent JAXA's Rapid Innovative payload demonstration Satellite-4, known as RAISE-4, to a circular orbit 336 miles (540 kilometers) above Earth. It was deployed there on schedule, about 54.5 minutes after launch.

The satellite's full name tells us broadly what it will do up there. RAISE-4 "will demonstrate eight technologies developed by private companies, universities, and research institutions throughout Japan," Rocket Lab wrote in a mission description.

 

"RAISE and Shine" continues a record-breaking year for Rocket Lab, which has now launched 19 missions in 2025. Sixteen of them have been orbital flights.

The other three were suborbital launches with HASTE, a modified version of Electron designed to help customers test hypersonic technologies in the final frontier.

Rocket Lab's previous single-year launch record was 16, set in 2024.
