Both NASA and the European Space Agency (ESA) yesterday released new photos of the interstellar comet 3I/Atlas.

First, NASA released the image on the right, taken on November 30, 2025 by the Hubble Space Telescope. At the time the comet was about 178 million miles away. It clearly shows the comet’s coma of material, surrounding a bright nucleus at the center. The streaks are background stars.

Next, the mission team for Europe’s Juice probe, on its way to Jupiter, released one small portion of a picture taken by its navigation camera. That picture is the second to the right.

During November 2025, ESA’s Jupiter Icy Moons Explorer (Juice) used five of its science instruments to observe 3I/ATLAS. The instruments collected information about how the comet is behaving and what it is made of. In addition, Juice snapped the comet with its onboard Navigation Camera (NavCam), designed not as a high-resolution science camera, but to help Juice navigate Jupiter’s icy moons following arrival in 2031.

Though the data from the science instruments won’t arrive on Earth until February 2026, our Juice team couldn’t wait that long. They decided to try downloading just a quarter of a single NavCam image to see what was in store for them. The very clearly visible comet, surrounded by signs of activity, surprised them.

Not only do we clearly see the glowing halo of gas surrounding the comet known as its coma, we also see a hint of two tails. The comet’s ‘plasma tail’ – made up of electrically charged gas, stretches out towards the top of the frame. We may also be able to see a fainter ‘dust tail’ – made up of tiny solid particles – stretching to the lower left of the frame.

The image was taken on 2 November 2025, during Juice’s first slot for observing 3I/ATLAS. It was two days before Juice’s closest approach to the comet, which occurred on 4 November at a distance of about 66 million km.

Because Juice is presently behind the Sun (as seen from Earth), most of the data it collected during its closest approach won’t be downloaded until February. This one partial image is only a fore taste.

China launches two small test communications satellites

9:35 am

China today successfully placed two experimental communications satellites into orbit, its solid-fueled Kuaizhou-1a rocket lifting off from its Jiuquan spaceport in northwest China.

China’s state-run press provided no information on where the rocket’s lower stages crashed. The rocket is supposedly owned and operated by a Chinese pseudo-company, but its solid-fueled heritage clearly comes from military missiles, and thus could only have been developed and used under the full supervision of China’s military.

The leaders in the 2025 launch race:

159 SpaceX
76 China (a new record)
15 Rocket Lab
15 Russia

SpaceX still leads the rest of the world in successful launches, 159 to 128.

“Blemish” on Orion hatch’s “thermal barrier” delays countdown rehearsal

9:24 am

According to a report yesterday, a countdown rehearsal two weeks ago for the Orion/SLS stack that also included the four astronauts to fly on the next mission was delayed because a “blemish” was found on the Orion hatch “thermal barrier.”

“Prior to the countdown demonstration test, the agency had planned to conduct a day of launch closeout demonstration. This demonstration was paused when a blemish was found on the crew module thermal barrier, preventing hatch closure until it could be addressed,” the statement read. “A repair was completed on Nov. 18 allowing the closeout demo to successfully complete on Nov. 19. To allow lessons learned from the closeout demo to be incorporated into the planning for the countdown demonstration test, the decision was made to proceed into water servicing next and place the countdown demonstration test after this servicing completes.”

It was not clear from the NASA statement how a ‘blemish’ prevented the closure of the hatch and NASA would not say exactly when the countdown rehearsal will take place. Declining to provide further details, the space agency spokesperson said: “NASA remains on track to launch Artemis 2 no later than April 2026 with opportunities to potentially launch as soon as February.”

NASA released no additional details, though it claimed this delay will have no impact on the launch schedule for the Artemis-2 mission, planned for launch no later than April 2026.

The lack of detailed information from NASA is disturbing. What was the “blemish?” It appears it was on the rubber gaskets that circle the hatch’s edge. What caused it? Was it some damage? A production flaw? NASA’s general silence forces us to consider more serious possibilities.

I continue to pray that these four astronauts are not going to end up as sacrificial lambs to the political scheduling demands that is forcing NASA to push on blindly, as it did with both the Challenger and Columbia failures, ignoring or minimizing issues that common sense should never be minimized.

An evening pause: I normally don’t post pauses that are not live and have no visuals, such as this one. However, in this case I have reasons for using this original recording of this wonderful song, which will become evident in tomorrow’s evening pause.

The first stage completed its 4th flight, landing on a drone ship in the Pacific.

The leaders in the 2025 launch race:

159 SpaceX (a new record)
75 China
15 Rocket Lab
15 Russia

SpaceX now leads the rest of the world in successful launches, 159 to 127.

Boeing is still not off the hook for its malfeasance behind the two 737-Max crashes that killed 346

3:06 pm

Boeing Logo

It turns out that one week after a judge approved a plea deal in early November between Boeing and the Justice Department that would allows the company to avoid a criminal prosecution for its malfeasance and fraud that led to two 737-Max airplane crashes that killed a total of 346 people — thus dismissing the pending criminal charges — the families of the victims filed an appeal, asking a higher court to overturn that deal.

The families had argued before U.S. District Court Judge Reed O’Connor that the Department of Justice’s (DOJ) non-prosecution agreement violated the judicial review provisions, which was reached behind closed doors without the families’ statutory right to confer. The writ of mandamus argues that no substantive proceedings before Judge O’Connor were held before he made his decision in favor of Boeing.

…DOJ initially presented Judge O’Connor with a non-prosecution agreement (NPA) that he rejected. Instead of coming back with something more stringent, DOJ presented Boeing with the lesser punishment of an NPA in which Boeing would merely pay a $243.6 million penalty, give $444.5 million to be divided amongst the 346 families, and make additional investments in its safety and compliance. In exchange, the DOJ agreed to dismiss the criminal charge against Boeing. On November 6, Judge O’Connor approved this revised NPA and granted the government’s motion to dismiss.

The families now look forward to the Fifth Circuit Court of Appeals to reverse this decision through its writ of mandamus. In the writ, Paul Cassell, pro bono, attorneys for the families and professor of the S.J. Quinney College of Law at the University of Utah, argued on behalf of the families’ that the government’s NPA with Boeing would not provide sufficient oversight of Boeing and failed to account for the fact that Boeing’s criminal behavior was found to have caused the deaths of 346 crash victims. Boeing’s CEO and its lawyers had admitted to the fraud in a guilty plea issued four years ago.

In 2021 Boeing itself pleaded guilty to malfeasance and corruption charges, and was given three years to clean up its act or face criminal prosecution. When after three years Justice found Boeing had instead lied to it while doing little to fix things, it first proceeded with prosecution, only to suddenly back off and make this plea deal.

Thus, the families’ case is strong. Boeing is an admitted criminal and has also done nothing to change its behavior. Whether the families can get the plea deal overturned, however, remains unknown. The legal system no longer can be trusted when it comes to big government contractors like Boeing. The government acts routinely to protect them (as Justice is doing here), and thus there will be heavy political pressure on the courts to turn down this appeal.

The insane terrain inside Mars’ Death Valley

12:30 pm

taffy terrain
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 27, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this a “twisted surface,” to which I think we all can agree. What we are looking at is a geological feature found only on Mars in only one region that has been labeled “taffy terrain” by scientists. According to a 2014 paper, the scientists posit that this material must be some sort of “a viscous fluid,” naturally flowing downward into “localized depressions.” Because of its weird nature I have posted many cool images of it in the past (see here, here, here, here, here, and here).

In the case of the image to the right, the red dot marks the peak of a small knob, with the green dot on the upper left the low point about 900 feet below. As you can see, the taffy has migrated into the depressions, as some flowing material would.

Ground-based telescope actually photographs an exoplanet

10:51 am

exoplanet imaged directly
Click for original movie.

Using a new instrument on the Subaru Telescope in Hawaii astronomers have not only discovered a massive exoplanet orbiting a star, they have been able to actually photograph the planet itself.

The arrow in the picture to the right shows that planet. That picture is a screen capture from a short movie complied from five observations taken over several months earlier this year, showing the planet as it orbited the star, the light of which is blocked out so as to not blind the camera. From the press release:

The newly discovered planet, HIP 54515 b, orbits a star 271 light-years away in the constellation Leo. With nearly 18 times Jupiter’s mass, it circles its star at about Neptune’s distance from our Sun. But the star and planet appear very close when seen from Earth; roughly the size that a baseball seen 100 km away would appear. The SCExAO system produced extremely sharp images allowing us to see the planet.

The astronomers also used this new instrument to image a brown dwarf star with a mass equivalent to sixty Jupiters about 169 light years away.

Yesterday’s Senate nomination hearing for Jared Isaacman was irrelevant; America’s real space “program” is happening elsewhere

10:20 am

Jared Isaacman
Billionaire Jared Isaacman

Nothing that happened at yesterday’s Senate hearing of Jared Isaacman’s nomination to be NASA’s next administrator was a surprise, or very significant, even if most media reports attempted to imply what happened had some importance. Here are just a small sampling:

To be fair, all of these reports focused on simply reporting what happened during the hearing, and the headlines above actually provide a good summary. Isaacman committed to the Artemis program, touted SLS and Orion as the fastest way to get Americans back to the Moon ahead of the Chinese, and dotted all the “i”s and crossed all the “t”s required to convince the senators he will continue the pork projects they so dearly love. He also dodged efforts by several partisan Democrats to imply Isaacman’s past business dealings with Musk and SpaceX posed some sort of conflict of interest.

What none of the news reports did — and I am going to do now — is take a deeper look. Did anything Isaacman promise in connection with NASA and its Artemis program mean anything in the long run? Is the race to get back to the Moon ahead of China of any importance?

I say without fear that all of this is blather, and means nothing in the long run. The American space program is no longer being run by NASA, and all of NASA’s present plans with Artemis, using SLS, Orion, and the Lunar Gateway station, are ephemeral, transitory, and will by history be seen as inconsequential by future space historians.
