An evening pause: Makes me think of Disney’s Peter Pan (1953) and Miyazaki’s My Neighbor Totoro (1988), about how some things only children can see.
Hat tip Judd Clark.
Courtesy of BtB’s stringer Jay. Early today because Diane and I have a social event this afternoon and I want this posted before we leave. It is the holiday season, which has made it hard for me to write any political essays yesterday or today.
Years late, it does look like Vulcan will finally launch in early January. Let us all pray all goes well.
Jonathan McDowell, who tweets this, has been tracking objects launched and in orbit for decades, so his suppositions carry weight.
It appears to me that these test legs are not full scale. It is also interesting how they bounce when they come down.
This post provides no video of the test, and is merely a tease for the video’s release next month. Why they can’t release it now suggests they want to do some clean-up and editing beforehand, which raises other questions.
Gee, maybe invading the Ukraine and cancelling its deal with OneWeb and Arianespace might not have been such a good idea, eh? The lost revenue, in the billions, might have helped pay for this.
This was hardly one of the most important firsts achieved during Apollo 8, but the imagery, as Jay notes, is cool. For the full history of Apollo 8’s 1968 manned Christmas mission to the Moon, read Genesis, the Story of Apollo 8.

Cool image time! The picture to the right, reduced and sharpened to post here, was taken on December 21, 2023 by the chemistry camera (ChemCam) on the rover Curiosity. Originally designed to take close-ups of rocks very nearby the rover, the science team over time discovered that they could also use this camera to get close-ups of very distant objects, providing them another way to study the geology in Gale Crater and on Mount Sharp.
The picture to the right I think shows the horizon area indicated by the arrow on the panorama above, taken the day before. Note the many many layers, a geological feature that Curiosity has discovered is ubiquitous on Mars. Over eons the entire surface of the red planet has been layered repeatedly by cyclical geological events, producing layers within layers within layers. I guarantee that when Curiosity gets closer to this cliff it will see layers inside the smallest layers ChemCam can see now.
The red dotted line on the panorama above indicates the approximate planned route that Curiosity will eventually take, cutting across in front of that mountain and turning south somewhere near but to the west of where the cliff in this picture is located.

Alpha seven seconds after liftoff
UPDATE #2: According to a Firefly tweet on X, the second stage failed to fire its second burn. The satellite however was deployed, communications established, and mission operations started. Though its orbit will decay prematurely, it appears the customer, the Space Force, will achieve most of its mission objectives. This should be considered a successful launch, albeit not one that Firefly will want to repeat in this manner.
UPDATE: It appears the upper stage might have had a problem in its final engine burn intended to circularize the orbit for deployment. Either the burn failed to occur, or did not fire correctly. See this tweet. (Hat tip Jay.) I have found other reports that indicate the same question.
The question now is whether this is considered a successful launch. One of its main tasks was to demonstrate fast assembly and prelaunch procedures, for the Space Force. This was accomplished. If the satellite cannot function however is isn’t a full success. I will wait for more information before deciding whether to remove it from the launch stats.

Firefly today successfully completed its second launch in 2023, its third launch overall, its Alpha rocket lifting off from its launchpad at Vandenberg in California.
With this launch Firefly also met its launch prediction for 2023, two launches. The mission was its second for the Space Force this year, both designed to test quick launch procedures. As of posting the payload has not been deployed.
The leaders in the 2023 launch race remain the same:
92 SpaceX
61 China
18 Russia
8 Rocket Lab
7 India
American private enterprise now leads China in successful launches 106 to 61, and the entire world combined 106 to 97. SpaceX still trails the rest of the world (excluding other American companies) 92 to 97.
Two Chinese astronauts yesterday completed a 7.5 hour spacewalk on that country’s Tiangong-3 space station to test a repair technique to what the state-run press said was minor damage on a solar panel from micrometeorites.
The EVA posed new challenges for the astronauts, according to Dong Nengli, deputy chief designer of China’s human spaceflight program. “For the previous extravehicular activities, the major tasks for astronauts were to install and check. This round of extravehicular activities on Thursday we call experimental servicing,” Dong told CCTV. “This time the astronauts operated on one of the solar wings. It is flexible, to a certain extent, and also very thin, which limits the space of operation to a certain degree,” Dong said.
Dong added that the successful EVA meant the teams had mastered the ability for some extravehicular repairs. Success was thus, “laying a solid foundation for us to guarantee the space station’s safety and reliability in the future.”
It must be noted that no specific details about what was done were provided, nor did the short video released by China showing highlights of the spacewalk show the specific repair work.
Nonetheless, there is an aspect of China’s space station that makes it a far more powerful national symbol than ISS: It is China’s alone, built, launched, occupied, and maintained by China alone. It fuels national pride in a way that ISS never has, because President Bill Clinton decided to use it in the 1990s for foreign policy concerns by giving the Russians an equal partnership. Neither the U.S. nor Russia have obtained the same kind of prestige at home and abroad because neither really built ISS on their own. It was a shared effort, which meant neither could claim it.
Archaeologists have uncovered a 2,300-year-old wall mosaic in almost perfect condition in Rome that had been part of a banquet room overlooking a garden.
Estimated to be around 2,300 years old, the work is part of a larger aristocratic mansion, located near the Roman Forum, that has been under excavation since 2018. Almost five meters long (16.4 ft) and featuring depictions of vines, lotus leaves, tridents, trumpets, helmets and mythological marine creatures, the mosaic scene was painstakingly created using mother of pearl, shells, corals, shards of precious glass and flecks of marble. The piece is framed by polychrome crystals, spongy travertine, and exotic, ancient Egyptian blue tiles.
What makes this discovery “unmatched,” said archaeologist Alfonsina Russo, head of the Colosseum Archaeological Park in charge of the site, is not only the incredible conservation of the mosaic, but its decoration which also features celebratory scenes of naval and land battles likely funded — and won — by an extremely wealthy aristocratic patron who commemorated the victories on their walls.
Though it is believed such tiled mosaics were common in the homes of wealthy Roman aristocrats, most have not survived in good condition, making this discovery significant as well as beautiful. In addition, the location of the house and the details within the mosaic could make it possible to actually identify the Roman who lived here, which in itself would be a major historical find.

The live stream can be found here, starting one hour before launch.
It will be unberthed and released by an astronaut in ISS using a robot arm, after which it will be de-orbited, burning up over the ocean.

The footage is only 18 seconds long, covering the final countdown and liftoff. For a full history go here. Frank Borman, Jim Lovell, and Bill Anders would go on to circle the Moon for 20 hours, read from the Old Testament on Christmas eve, and essentially win the 1960s space race for the free world.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 30, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
It shows what appears to be a glacial flow of ice, flowing downhill to the southwest and inside a wide canyon about three miles across. The canyon rims to the north and south are about 2,000 to 2,100 feet above the canyon’s lowest point, indicated by the string of “+” signs.
This close-up view immediately suggests a canyon whose glacier flows outward to the southwest into open lowland terrain, though the three craters, because they are undistorted, suggests that this flow is presently not active. That suggestion however would be wrong. It is always necessary to understand Martian geology to not only take close-in views at high resolution, but to zoom back and see the terrain in context.

The annotated image above was taken by the Hubble Space Telescope on October 22, 2023, showing Saturn, its glorious rings, and several of its dozens of moons from a distance of about 850 million miles. For the unannotated version, go here. Of all the features, the spokes in the rings are the most intriguing.
Saturn’s spokes are transient features that rotate along with the rings. Their ghostly appearance only persists for two or three rotations around Saturn. During active periods, freshly-formed spokes continuously add to the pattern. In 1981, NASA’s Voyager 2 first photographed the ring spokes. Hubble continues observing Saturn annually as the spokes come and go. This cycle has been captured by Hubble’s Outer Planets Atmospheres Legacy (OPAL) program that began nearly a decade ago to annually monitor weather changes on all four gas-giant outer planets.
Hubble’s crisp images show that the frequency of spoke apparitions is seasonally driven, first appearing in OPAL data in 2021 but only on the morning (left) side of the rings. Long-term monitoring shows that both the number and contrast of the spokes vary with Saturn’s seasons. Saturn is tilted on its axis like Earth and has seasons lasting approximately seven years.
This year, these ephemeral structures appear on both sides of the planet simultaneously as they spin around the giant world. Although they look small compared with Saturn, their length and width can stretch longer than Earth’s diameter!
Though the origin of the spokes remains unsolved, the leading theory proposes they are caused by interactions between Saturn’s magnetic field and the seasonal changes in solar radiation.
Link here. The essay details carefully the problems they have faced, and how they have not only overcome them but used them to refine operations to squeeze far more capabilities out of the helicopter, beyond its initial design.
Saving flight time saves energy, reduces heating, and provides more freedom to use slower speeds to tiptoe around disruptive terrain that might otherwise endanger or significantly degrade the landing accuracy of the helicopter. Higher speeds and higher accelerations reduce the time needed to execute a given flight path. Higher altitudes permit higher speeds, as the wider field of view helps to keep ground features in view of Ingenuity’s navigation camera longer, counteracting the effect of increased speed. Expanding Ingenuity’s flight envelope had the potential to relax flight planning constraints and allow Ingenuity to operate more effectively alongside Perseverance.
As a result, beginning with flight 45 the team has made changes to increase flight speeds and acceleration at every point of every flight, thus allowing the helicopter to fly higher and farther with less strain.
This report however does not provide any information on Ingenuity’s last two flights, especially its 68th, which did not go as planned. The helicopter appears to be in good shape (the team has already planned the 69th flight, which was supposed to happen two days ago), but a more detailed update would be appreciated.
The landing site for Astrobotic’s Peregrine lunar lander
In preparation for its targeted January 8, 2024 launch, ULA’s Vulcan rocket has now been fully stacked for first time in its assembly building at Cape Canaveral.
ULA’s new rocket has rolled between its vertical hangar and the launch pad at Cape Canaveral Space Force Station several times for countdown rehearsals and fueling tests. But ULA only needed the Vulcan rocket’s first stage and upper stage to complete those tests. The addition of the payload shroud Wednesday marked the first time ULA has fully stacked a Vulcan rocket, standing some 202 feet (61.6 meters) tall, still surrounded by scaffolding and work platforms inside its assembly building.
It will next be rolled to the launchpad for some final checks prior to launch on January 8, 2023. Unlike most first launches, it carries a real payload, Astrobotic’s Peregrine lunar lander, which hopes to softly place several NASA and commercial payloads near the Gruithuisen Domes in the northwest quadrant of the Moon’s visible hemisphere, as shown on the map above.
Faced with stiff opposition from industry and politicians from both parties in Congress to its regulatory proposal issued in mid-November, the White House yesterday released what it called a “policy framework” for implementing that proposal.
You can read this policy framework here [pdf]. It is filled with high-sounding claims about its goal is to encourage private development and reduce red tape, but in the end it only adds more government entities to the entire bureaucracy that regulates commercial space. From the framework itself:
The Secretaries of Commerce and Transportation will co-lead a Private Sector Space Activities Interagency Steering Group in consultation with the Chairperson of the Federal Communications Commission (FCC), comprising representation from the Departments of Defense, Energy, Homeland Security, Interior, and State, the National Aeronautics and Space Administration (NASA), the Office of the Director of National Intelligence, the Office of Science and Technology Policy, and any other Federal entities with expertise or equities pertaining to private sector novel space activities, including relevant stakeholders from the Executive Office of the President. The Steering Group serves as a coordinating body to ensure that the U.S. Government oversight system is prepared to meet U.S. priorities while taking into consideration the competitiveness of U.S. industry now and into the future.
One of the criticisms of the White House proposal from mid-November was that it would split regulation between Commerce and Transportation, thus increasing the complexity for commerical companies. This steering group is clearly an effort to answer those complaints, but based on this proposal, it simply adds one more bureaucratic layer to the mix, making things even more complicated.
The framework also calls for the expansion of the government’s regulatory footprint on several fronts, such as controlling orbital debris, and achieved through “expanding existing, or establish new, federal advisory committees to account for all expanded space authorities in furtherance of this Framework and related legislative proposals.”
From the viewpoint of freedom, this entire proposal reads like a zombie end-of-the-world horror film, with bureaucratic zombies appearing endlessly from all directions, aimed at consuming any independent private company as quickly and as thoroughly as possible.
The original commercial space act proposal from Congress, that the Biden administration (and most Democrats) oppose but carries the endorsement of the private commercial space industry, was passed by its House committee, but still needs to be voted on by the full House, as well as the Senate. Because it remains in limbo, the White House has issued this framework, in the hope it can give its side the ammunition needed to defeat that bill and replace it with the White House’s.
Link here. I have also embedded the movie below. The movie was made from fourteen years of observations by the Fermi Gamma-Ray Telescope in orbit around the Earth. From the press release:
Gamma rays are the highest-energy form of light. The movie shows the intensity of gamma rays with energies above 200 million electron volts detected by Fermi’s Large Area Telescope (LAT) between August 2008 and August 2022. For comparison, visible light has energies between 2 and 3 electron volts. Brighter colors mark the locations of more intense gamma-ray sources.
“One of the first things to strike your eye in the movie is a source that steadily arcs across the screen. That’s our Sun, whose apparent movement reflects Earth’s yearly orbital motion around it,” said Fermi Deputy Project Scientist Judy Racusin, who narrates a tour of the movie, at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
Most of the time, the LAT detects the Sun faintly due to the impact of accelerated particles called cosmic rays – atomic nuclei traveling close to the speed of light. When they strike the Sun’s gas or even the light it emits, gamma rays result. At times, though, the Sun suddenly brightens with powerful eruptions called solar flares, which can briefly make our star one of the sky’s brightest gamma-ray sources.
The movie shows the sky in two different views. The rectangular view shows the entire sky with the center of our galaxy in the middle. This highlights the central plane of the Milky Way, which glows in gamma rays produced from cosmic rays striking interstellar gas and starlight. It’s also flecked with many other sources, including neutron stars and supernova remnants. Above and below this central band, we’re looking out of our galaxy and into the wider universe, peppered with bright, rapidly changing sources.
Most of these are actually distant galaxies, and they’re better seen in a different view centered on our galaxy’s north and south poles. Each of these galaxies, called blazars, hosts a central black hole with a mass of a million or more Suns.
Fermi is essentially mapping the high energy objects of the entire universe.

Russia early this morning successfully launched a classified military satellite, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in northern Russia.
No word on where the rocket’s strap-on boosters or first stage crashed within Russia.
The leaders in the 2023 launch race:
92 SpaceX
61 China
18 Russia
8 Rocket Lab
7 India
American private enterprise still leads China in successful launches 105 to 61, and the entire world combined 105 to 97. SpaceX by itself now trails the rest of the world (excluding other American companies) 92 to 97.
Gearing up for Starship/Superheavy orbital test flight #3: Starship prototype #28 today successfully completed a full duration static fire test, with all six engines firing for about five seconds.
The link goes to SpaceX’s X feed, and shows that test.
This is more evidence that SpaceX intends to be ready in all ways to do that third orbital test flight of Superheavy/Starship by mid-January, at the latest. It also suggests the company is getting close to finishing its investigation into the previous test flight in mid-November.
Of course, none of this means it will launch in mid-January. I predict SpaceX will be stuck twiddling its thumbs waiting for a launch license from the FAA, which will also be waiting for an okay from Fish & Wildlife. Both will likely be forced to work as slowly as possible, likely because of interference from the White House.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 20, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It features a 250-foot-high north-south cliff that appears to have numerous horizontal layers within it.
Moreover, both on the plateau above the cliff as well as the floor below it, the entire surface seems to resemble a thick snow/ice field, made even more evident by the distortion of many craters and the apparent glacial material inside each crater.
The layers suggest that this ice was laid down in a series of cycles. During cold periods snow fell and accumulated as ice over time. When things became warmer some of that ice sublimated away, but not all. With the next cold cycle a new layer was put down.
The many layers suggest many climate cycles on Mars, none of which were caused by SUVs or coal-firing electrical power stations.

How the modern Democratic Party has evolved
madly to the left, according to Elon Musk
In 2022 Elon Musk essentially completed the long process of going from what he described as a moderate who had previously voted overwhelming for Democrats to a Republican voter strongly hostile to the present Democratic Party.
He announced this shift in a tweet on May 18, 2022, in which he said the following:
In the past I voted Democrat, because they were (mostly) the kindness party.
But they have become the party of division & hate, so I can no longer support them and will vote Republican.
Now, watch their dirty tricks campaign against me unfold. [emphasis mine]
In the almost twenty months since Musk made that statement, his prediction of a “dirty tricks campaign” by the Democrats has become quite evident and true. Numerous federal agencies under the control of President Joe Biden began taking strong actions to stymie Musk’s companies, sometimes abusing the law in what appear to be legitimate ways, and sometimes abusing power in ways that are absurd. Below is a short list, many of which have been repeatedly reported here at Behind the Black:

UPDATE: See this December 26, 2023 post for more accurate information.
Original post:
————————–
According to a recent update to the flight log of the Mars helicopter Ingenuity, it finally completed its 68th flight on December 15, 2023, not on December 9, 2023 as announced in the flight plan on December 8th.
More significantly, the flight only traveled 1,289 feet (393 meters), not the 2,716 feet (828 meters) intended. The flight was supposed to travel out to the northeast and then return to its take-off point, indicated by the green dot on the map above, completing a “flight test” as well as scouting the ground below. It appears it did not do this, but where the 68th flight actually went and landed has as yet not been released. According to the flight plan, Ingenuity likely landed somewhere in Neretva Vallis to the northeast, as indicated by the green line.
What we do know is that the engineering team knows enough about Ingenuity’s condition to release today the flight plan for the 69th flight, which was actually scheduled to occur yesterday. That flight plan calls for Ingenuity to travel about 2,300 feet to the east-northeast and then return to its take-off point.
Meanwhile, Perseverance (the blue dot) is working its way west back to its planned route, the red dotted line.
The Senate yesterday passed a short term extension of the regulatory “learning period” at the FAA that limits its ability to regulate commercial space.
[The Senate] quickly passed an extension of the FAA’s authorization, a final piece of “must pass” legislation before the end of the year. The bill (H.R. 6503) passed the House on December 11. Among other things, it extends the “learning period” for commercial human spaceflight until March 9, 2024 that otherwise would have expired on January 1. The learning period, or “moratorium,” prohibits the FAA from promulgating new regulations on commercial human spaceflight while the industry is in its infancy.
The president still needs to sign this bill, but that is expected.
Originally passed in 2004 as an eight-year period, this “learning period” has been extended several times since. The industry wants a longer extension, as it still considers itself quite rightly to be in an experimental test phase, not operational in the sense of airplane manufacture.
Not that this extension matters. It appears in the past two years that the regulators at the FAA have decided to ignore the law and make believe this learning period really doesn’t exist, based on how that agency has treated test launches by SpaceX and others. Rather than let their launches proceed quickly as tests, the FAA has begun to treat each test as an operational flight that requires a long investigation before further launch approvals are given.
Unless there is a major change in leadership in the White House, we should expect a major slow-down of the American launch industry in the coming years, regardless of whether this “learning period” is extended or not.

Cool image time! The picture to the right, cropped and reduced to post here, was released today by the science team of the Hubble Space Telescope, and shows an irregular dwarf galaxy that is about seven million light years away.
Twelve camera filters were combined to produce this image, with light from the mid-ultraviolet through to the red end of the visible spectrum. The red patches are likely interstellar hydrogen molecules that are glowing because they have been excited by the light from hot, energetic stars. The other sparkles on show in this image are a mix of older stars. An array of distant, diverse galaxies appear in the background, captured by Hubble’s sharp view.
The data used in this image were taken by Hubble’s Wide Field Camera 3 and the Advanced Camera for Surveys from 2006 to 2021.
The picture was taken as part of a study of dwarf galaxies, their make-up, and how their mergers eventually create the larger galaxies like the Milky Way.
After 20 years of development, the first eighteen segments of Europe’s Extremely Large Telescope (ELT) have now shipped to Chile, with another 780 more segments to go.
The assembly of the telescope’s massive mirrors will take place over the next 4 years. This week, the first segments of what will be the main mirror – called ‘M1’ – arrived in Chile.
Once complete in 2028, these segments will create a primary mirror 40 meters across, about 131 feet, four times larger than the 10.4 meter Gran Telescopio in the Canary Islands, presently the largest telescope in operation.
Because of scheduling conflicts impacting other SpaceX launches now, SpaceX and Intuitive Machines have delayed the launch of the latter’s Nova-C lunar lander from a mid-January to a mid-February launch window.
The conflict involves the use of the launchpad, that the Falcon Heavy also uses. Technical issues had forced SpaceX to reschedule its next launch to December 28, 2023, leaving little time afterward to reconfigure the pad for the Falcon 9 Nova-C mid-January launch window. Any Falcon Heavy launch delays due to weather would likely make that mid-January window impossible, so the companies have decided better to reschedule now.
Nova-C is targeting a crater rim near the Moon’s south pole, as shown on the map to the right. The floor of that crater is thought to be permanently shadowed, but Nova-C does not have the capability to enter it. This mission is mostly an engineering test mission, to prove Intuitive Machine’s design. If it works, it will operate on the Moon surface for one lunar day, about two weeks. The company then has two more lunar missions contracted with NASA, with the next mission aiming to fly in 2024 as well.

The mission was unmanned. The link is cued to just before launch. More information about this flight here.
The antenna can also be retracted.
Though it appears there are no objects close enough for it to fly past, it is still gathering a lot of detailed information of the outer parts of the solar system.
Failure theater: In a deal worked out suddenly between the board of regents at the University of Wisconsin and the state legislature, the university will get $800 million for infrastructure improvements and pay raises in exchange for imposing some limited reductions in its Diversity, Inclusion, and Equity (DEI) programs.
The deal also requires UW system campuses to refrain from adding new DEI positions through December 2026. Administrators must also reassign at least one third of their current DEI-focused employees to roles dedicated to academic and student success. Mandatory DEI statements in admissions and hiring are also to be abolished under the deal, and efforts to fund a conservative professorship at UW-Madison must be launched, according to the terms.
You can read the actual language of this deal here [pdf]. The deal also requires the university to replace its Target of Opportunity Program (TOP) — which established systems to favor hiring minorities over others — with a new “alternative program focused on recruiting faculty (regardless of their identity or ethnic/racial background) who have demonstrated the ability to mentor ‘at risk’ and/or underrepresented students to achieve academic success and who have demonstrated academic and research excellence.”
Does this deal do what it appears to, reduce or eliminate the very racist DEI program at the University of Wisconsin? Hardly. » Read more

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 4, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled a “terrain sample” by the science team, it was likely shot not as part of any specific research project but to fill a gap in the schedule so as to maintain the camera’s proper temperature. When the camera team has to do this they try to pick targets that are of some interest. Usually they succeed, considering the enormous gaps we presently have of Mars’ geological history.
This picture is no different. It shows a land of buttes and mesas, all ranging from 20 to 200 feet high, surrounded by canyons filled with ripple dunes of Martian dust. If you look at the floor of those canyons closely, you will notice that where there are no ripple dunes the ground is slightly higher and smooth. It is as if that ground was a kind of sandstone that was eroded away by wind into sand, which then formed the dunes.
