Link here. The author does a nice job summarizing the problems now becoming evident as the administration state strives to expand its power and control. Though he gives space to both sides, allowing the defenders of that administrative state to explain why strong regulations are good, he doesn’t bow to those defenders, as do too many modern journalists.
That he quotes me extensively (and has has told me personally that he is a regular reader of Behind the Black), might have something to do with this. He isn’t parroting my positions, however, in this essay, but giving his own perspective.
Definitely worth reading.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 21, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The science team labels this “patterned ground.” I see instead a whole range of inexplicable Martian geological features that, while each has been documented previously, each remains puzzling as to its formation process.
First there is the stucco-like peaks of all sizes on the upper left. This surface really looks like it had been wet plaster covered with Saran Wrap that had its peaks pulled up when that wrap was pulled off quickly.
Then there is brain terrain on the right. Always associated with glacier features on Mars, these convolutions are unique to Mars and as yet not entirely understood.
Next there is the circular arc on the middle left. It appears to be the remains of an impact crater now filled partly, but if so why has its northern rim disappeared so completely?
If you look close at the image above as well as the full image, you will find other mysterious features as well.
The location is the white dot on the overview map above. The rectangle in the inset shows the area covered by this picture, part of the floor of an unnamed eighteen-mile-wide and one-mile deep crater. The glacial material that appears to fill its interior as well as the splash apron that surrounds it all suggest the ground here is impregnated with water ice. Located as it is on the western end of the 2,000-mile-long north mid-latitude strip I dub glacier country — where practically every image shows glacial features — this conclusion is not surprising.
In fact, this photo illustrates well the alieness of Mars. We understand glaciers and ice, but on Mars, with its very cold temperatures, one-third Earth gravity, and thin atmosphere, those glaciers and ice are able to do things that we don’t yet understand. Untangling these geological processes will take decades of work, and likely will not be completed until people can walk the Martian surface and study it up close.
And won’t that be fun?

Scientists have proposed a project to send an unmanned probe to Oumuamua, using the Earth, Jupiter, and then the Sun to slingshot onto a path that would catch up with the interstellar object on its journey leaving the solar system in the mid-2050s.
The project, dubbed Lyra, was first proposed in 2023. The scientists have now revised the plan to account for the greater speeds needed to catch up with Oumuamua as it continues to move away from us. It is still within the solar system, but it is moving away very fast.
The graphic to the right, a screen capture of an animation at the link, shows the spacecraft as it finally approaches the interstellar object in 2055. To get there it would launch in the early 2030s, slingshot past the Earth to reach Jupiter, which would then slow it down so that it would fall back to the Sun, passing it by less than 450,000 miles, which would slingshot it out to Oumuamua (with the help of an additional engine burn). To survive the close solar approach it would use the same technology used by the Parker Solar Probe, which has already successfully flown that close to the Sun.
It seems this is an entirely worthwhile project, since Oumuamua continues to baffle scientists as to its nature. While most belief it is a natural but very unusual interstellar asteroid, none can dismiss the possibility that it instead an alien spacecraft. The data precludes nothing. Getting close to it seems worthwhile, no matter what.
For me, that rendezvous will happen when I would be 102 years old. I don’t think I’ll be here to see it.

Japan’s H2A rocket today successfully launched a new military surveillance satellite designed to observe North Korean’s missile launch sites.
The live stream of the launch is here, cued to T-10 seconds.
New reports had previously reported the last launch of the H2A occurred in September 2023, launching Japan’s SLIM lunar lander and XRISM X-ray telescope. This was obviously incorrect. Today’s launch appears to close out the H2A manifest, leaving Japan rocketless until it can get both its new H3 and grounded Epsilon rockets operational.

Boeing on January 9, 2023 successfully completed a parachute drop test of its Starliner capsule, testing whether the redesigned connection between the chutes and the capsule was now meeting proper safety specifications.
The drop test, which used a Starliner parachute system attached to a dart-shaped sled the same weight as a Starliner, was performed to confirm the functioning of a redesigned and strengthened soft link joint that is part of the network of lines connecting the parachutes to the spacecraft. The test also validated a change to strengthen one textile joint in the parachute, increasing overall parachute robustness. As with other capsules, Starliner relies on parachutes to land safely when it returns to Earth.
Engineers are still analyzing the results, though the parachutes worked as planned. The first manned mission of Boeing’s commercial capsule is now scheduled for April 2024, only four years late as well as four years after SpaceX accomplished the same thing. It still remains staggering that the company did not find out about that soft link joint when it was designing the capsule, instead of only months before the first manned mission last year. It is not as if the use of parachutes to land capsules is cutting edge technology.

An evening pause: This video is not what it seems. The sax player, Lawrence Mason, has created a cover of this Dave Brubeck song by editing and playing over the Dave Brubeck quartet playing another song in 1965. As he notes on the youtube page, he did it as a tribute to “Paul Desmond (saxophonist with the Dave Brubeck quartet – the anniversary of his death is at the end of this month) [May 2020].”

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on September 10, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label simply as a “double-rim crater.”
If you look close you might not be unreasonable to call this instead a triple-rim crater, as there appear to be two rings on each side of the highest crater rim.
Multple rings in craters are not rare. We see many on the Moon. Most however are associated with very large impacts, and are an expression of the ripples formed at impact, not unlike the ripples seen when you drop a pebble in water. Unlike water ripples, the ripples formed in rock are impact melt that quickly refreezes, thus capturing those ripples as concentric rings.
In this case, these rings likely signal not freezing rock but freezing ice.

Anthony Fauci: the liar-in-chief during
the Wuhan panic
This week Anthony Fauci was brought before a committee in the House of Representatives for closed-door hearings on his actions during the COVID epidemic in 2020-2021. Though supposedly private, the committee has been providing detailed recaps of Fauci’s testimony.
What it has learned is that Fauci was not only a chronic liar during his time as director of the National Institute of Allergy and Infectious Diseases (NIAID), he was also utterly incompetent as both a scientist as well as an administrator.
None of this really is news. As early as December 2020 Fauci admitted publicly that he had purposely misstated facts and scientific data for political reasons. Repeatedly I have reported many other examples of his dishonesty and incompetence (see for example these posts from June ’21, April ’22, September ’22, November ’22, and September ’23).
Nonetheless, Fauci’s testimony now is worth reviewing, because it underlines starkly how he misled and misinformed the public, causing great harm for no gain.
First, he admitted in testimony that the demands by him and the government that everyone maintain a six-foot distance during the epidemic was utter garbage, based on no scientific data at all.
In Tuesday’s session, Fauci admitted that the six-foot social distancing recommendation “was likely not based on any data,” according to the committee. “It just sort of appeared,” it wrote, quoting Fauci.
In August 2020 I found evidence suggesting the only source for this absurd rule came from a high school science project. Fauci has now essentially confirmed this, admitting that there is no legitimate science behind the six-foot rule.

A new false color infrared image from the Webb Space Telescope has revealed an unexpected structure extending out from the two debris disks that surround the near-by star Beta Pictoris, with computer modeling suggesting might this structure have been the result of a large collision as recently as only 100 years ago.
That false-colr image is the right, with this newly discovered structure, described by the scientists as resembling “a cat’s tail”, on the right side. The infrared light of the star has been blocked in the center in order to see the details of the disk.
Webb’s mid-infrared data also revealed differences in temperature between Beta Pic’s two disks, which likely is due to differences in composition. “We didn’t expect Webb to reveal that there are two different types of material around Beta Pic, but MIRI clearly showed us that the material of the secondary disk and cat’s tail is hotter than the main disk,” said Christopher Stark, a co-author of the study at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The dust that forms that disk and tail must be very dark, so we don’t easily see it at visible wavelengths — but in the mid-infrared, it’s glowing.”
To explain the hotter temperature, the team deduced that the dust may be highly porous “organic refractory material,” similar to the matter found on the surfaces of comets and asteroids in our solar system. For example, a preliminary analysis of material sampled from asteroid Bennu by NASA’s OSIRIS-REx mission found it to be very dark and carbon-rich, much like what MIRI detected at Beta Pic.
In an attempt to explain the cat’s tail, the scientists used computer models, which suggested it might have been caused by an event that produced a lot of dust, such as a collision between two large objects in the debris disk, and that event could have happened as recently as a hundred years ago.
This hypothesis remains unconfirmed, with much more data required before a final explanation can be accepted.
Using data from the TESS space telescope, astronomers have discovered an Earth-sized exoplanet in a 4.2 day orbit around a G-type star like our Sun about 70 light years away.
The tidally locked planet is very close to Earth size (it is approximately 1.1 times the diameter of our own planet) and it’s orbiting a star that’s similar to the size of our Sun (the star is about 0.91 the size and 0.99 the mass of the Sun).
The star in this system is a G-type star, the same type as our Sun. But HD 63433 d orbits much closer to its star than we do, with a minuscule 4.2 day long “year” and extremely high temperatures on its dayside.
To read the research paper, go here. At an estimated age of only 400 million years, this exoplanet and its solar system of at least two other planets is much younger than the 4.5-billion-year-old Earth. Though the press release and paper note the possibility that it is similar in many ways to Io, a volcanic planet covered with lava, we don’t know this. All we know is that it is roasted by its star by orbiting so close to it.
In what might be the first step in assemblying Blue Origin’s New Glenn rocket for the first time (followed by a launch), the company yesterday transported the rocket’s first stage from its factory to its launchpad hanger.
Transported by a series of multiwheeled carriages and an arching structure, the 189-foot-tall first stage for what will be a 320-foot-tall rocket when fully assembled traveled horizontally on a 22-mile trip from the New Glenn factory in Merritt Island through Kennedy Space Center over to Cape Canaveral Space Force Station where Blue Origin has a hangar and launch pad at Launch Complex 36.
Jeff Bezos has said the company plans that first launch before the end of this year, though the company has been making this same promise now for the last three years, and is years behind schedule. What makes this promise different however is that this time we are seeing actual hardware moving towards the launchpad.
The article also gives a rough update on the company’s effort to manufacture the many BE-4 rocket engines needed for New Glenn (7) and ULA’s Vulcan rocket (2). The two engines for the next Vulcan launch in April are presently undergoing final testing at Blue Origin’s test facility in Texas, and the company says it is about to ramp up production. It thus appears that getting enough engines built is still the main obstacle to launch. We shall finally know later this year if Blue Origin has solved this problem.
