Hazegrayart – A visual comparison of the space age’s unbuilt rocket concepts
An evening pause: None of course were ever built. Most were government concepts that would have cost a fortune and never considered profit as a motive. The last concept is the wildest, and uses exploding nuclear bombs to propel it.

Movies when our culture was not run by barbarians
Today’s essay will in a sense be part two of an essay I wrote earlier this week, entitled “We are becoming a nation of barbarians”. Then, I tried to show the decay in the western civilization by describing the accepted — almost encouraged — crudeness of modern language. While public cursing could easily be consider only a small and trivial issue, I think the increased use of obscene language in normal discourse is equivalent to the “broken windows theory” of psychology, which posits that minor visible signs of disorder and misbehavior encourage further and worse disorder and misbehavior, eventually leading to collapse.
Today I’d like to instead give some examples of the much more civilized nature of popular entertainment from only a half century ago, in order to contrast this with the present. To do this I will cite just four movie examples, and challenge everyone today who is a passionate fan of modern films to watch them (all of which are available for free on the internet) and recognize the differences that I will describe. If you like movies, you will enjoy the experience, but I warn you, modern popular entertainment films do not compare well with these mid-twentieth century pop movies.

Mars’ endless cycles of glacial activity
Click for original image.
While the images being sent to us from Mars Reconnaissance Orbiter (MRO) repeatedly show features that appear convincingly like glaciers, the data is also beginning to tantalize us with evidence of the endless glacial cycles that have occurred on Mars.
The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 27, 2023 by MRO’s high resolution camera. The red dot in the inset of the overview map above shows the location, the western flanks of an apron that surrounds a 3,800-foot-high mesa in the chaos region Deuteronilus Mensae, the western end of the 2,000-mile-long mid-latitude strip of chaos regions I dub glacier country, because every image seems to show some form of glacial feature.
Today’s picture is no different. The apron shown here drops the last 1,000 feet of the mesa’s total 3,800-foot height, during which it shows dozens of what the scientists label “parallel lines.” These lines likely reveal the layers of glacial ice in this apron, with the older layers larger and more extensive. Apparently, with each growth cycle the glacier obtained less snow from the atmosphere, so the more recent layers grew less.
In other words, the amount of water on Mars has been declining with time.
Untangling these numerous layers will undoubtedly give us a remarkably detailed history of Mars entire geological history. Unfortunately, that untangling cannot happen until we have boots on the ground, on Mars, able to drill core samples from many different places.
Regulatory problems for Saxavord spaceport in Shetland?
In a short statement reported in the local Shetland press, the under-construction Saxavord spaceport in Scotland has apparently laid off some construction workers, claiming it has done so “because the project was so far ahead of schedule.”
The statement however also alluded to the United Kingdom’s Civil Aviation Authority (CAA), which must issue a launch license before any launches can occur.
SaxaVord Spaceport said: “SaxaVord continues to have excellent dialogue with the authorities and is fully expecting to receiving its spaceport licence very soon from the Civil Aviation Authority. We are looking forward to hosting vertical rocket launches in the coming months.”
The application for this launch license was submitted in November 2022. It appears that the CAA still needs a year or more to approve any launch license, a slow and endless process that if not corrected will make launches from the United Kingdom completely unprofitable.
Saxavord had hoped to get its first launch off this year, by fall. It now appears that will not happen.
Commercial spaceport in Australia signs its first launch contract
The red dot marks ELA’s location, on the north coast of Australia.
Australia’s first commercial spaceport, Equatorial Launch Australia (ELA), has signed a multi-launch contract with a South Korean startup rocket company, Innospace, with the first launch targeting April 2025.
Though Innospace successfully launched a suborbital test flight in March, it has not yet launched a rocket to orbit. Meanwhile, ELA is negotiating with a number of other rocket companies, but it also appears it is having problems with the administrative state in the U.S.
The South Korean company is first off the blocks as it is not subject to the strict technological transfer regulations applied by the United States.
[ELA’s CEO Michael] Jones says delays to the signing of a Technological Safeguards Agreement (TSA) between Canberra and Washington is holding up several potential US customers. “We’re still waiting with bated breath for the TSA, despite a bilateral announcement by Biden and Albanese in Japan in early June that the deal was done and dusted,” he explains. “We were all expecting it to be released by the end of the financial year and the process of being endorsed by Parliament begun”.
A pattern of delay and intransigence in Washington, blocking commercial space, does seem to be developing since Joe Biden took over as president.
Luna-25 takes first image of lunar surface
Click for interactive map. Zeeman is located on the lower left.
Russia’s state-run press today issued the first picture taken by Luna-25 after entering lunar orbit two days ago. That picture, to the right and cropped and reoriented to post here, shows part of Zeeman Crater at 75 degrees south latitude and 135 degrees west, on the far side of the Moon. From the TASS announcement:
“The Luna-25 spacecraft, flying in a circular orbit as the Moon’s artificial satellite, has taken pictures of the lunar surface with television cameras of the STS-L system. The image, taken today at 08:23 Moscow time, shows the southern polar crater Zeeman on the far side of the Moon. The coordinates of the crater center are 75 degrees south and 135 degrees west,” the state corporation said. Roscosmos said the Zeeman crater is of great interest to researchers. Its rim rises eight kilometers above its relatively flat floor.
The picture shows Zeeman’s southern rim to the left, with its pockmarked crater floor to the right. The crater the lander is targeting, Broguslawsky Crater, sits in the opposite hemisphere of Zeeman, slightly closer to the south pole but on the Moon’s near side.
August 17, 2023 Zimmerman/Pratt on Texas podcast
I appeared today for about 45 minutes with Robert Pratt as part of his Pratt on Texas podcast, discussing a whole range of blacklists stories with him. We also talked about my most recent book, Conscious Choice, which if you are a fan of my work and have not yet read it you need to buy it now! No more delays or procrastination! You have your orders.
This is part one of a two part interview, the second half of which Pratt plans to post this coming week.
That podcast is embedded below. It can also be listened to here.

- New images of the floor of Blue Origin’s BE4 rocket engine production facility in Alabama
Jay sent me a video of this same production facility in April. Compare the visuals in that video at around 42 seconds with today’s image. That nozzle on the platform appears to be the same nozzle in both shots, unmoved in four months. Moreover, the floor seems as inactive now as then. If I was ULA this data would make me very very worried about getting the engines I need for Vulcan on the scheduled required.
- China releases a photograph of part of Valles Marineris, taken by its Tianwen-1 Mars orbiter
The image covers a very large area. For high resolution close-up images of various features within this picture, see these cool images from July 2021, September 2021, May 2022, and July 2022.
- SpaceX lifted nearly 10 times as much mass to orbit as China in the second quarter 2023
The graph illustrates how false the notion has always been that you must have a heavy lift rocket to get a large amount of mass to orbit. All you really need is a cost-effective and efficient reusable rocket that can launch frequently, such as the Falcon 9. Heavy lift would be nice, but if it isn’t reusable and cost effective, it just won’t do the job.
- Russia and ESA are negotiating a new agreement for the use of Europe’s robot arm on Russia’s part of ISS
The arm is there already and installed. I wonder what they are negotiating.
Today’s blacklisted American: California city harasses Rabbi for having guests over for dinner
Beverly Hills: Where Jews are forbidden to pray
They’re coming for you next: The headline above is literally true, though you need to know a bit about Judaism, especially Orthodox Judaism, to understand what I mean exactly.
The story is this: Because Rabbi Levi Illulian, like all Orthodox Jews, routinely invites friends and acquaintances to join his family for Friday night dinner and Saturday lunch at his home during the weekly Saturday Sabbath, officials in Beverly Hills in California sent him a “notice of violation” on June 12, 2023, telling him that these dinners must cease, and ordered him to “terminate all religious activities” that included any “non-residents.” It also threatened him with civil and criminal proceedings if he didn’t stop praying with friends in his home.
It appears that the city’s actions were instigated by the complaints of one unnamed neighbor. As described in the letter [pdf] sent by Illulian’s lawyers to the city in response to its notice of violation, after receiving those two complaints in February and March about parking, trash, and noise, the city instituted an investigation that involved stake-outs of Illulian’s home and the use of drones over his property (without a warrant) in which city officials “not only tallied the number of individuals and cars coming and going from the Home, but also photographed Rabbi Illulian’s guests.”

The inexplicable behavior of Martian dust devils
Click for original image.
Today’s cool image illustrates the puzzling inclination of Martian dust devils to strongly favor specific regions on the Martian surface, for reasons that at present no one can confidently explain.
The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on June 28, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a plethora of dust devil tracks, almost all of which have an east-west orientation. Moreover, the tracks seem uninfluenced by the surface topography, continuing on their path without deviation, even as they cross cliffs, craters, and mounds. The orientation tells us the direction of the prevailing winds, though I don’t know if those winds blow to the east or to the west.
What makes this image revealing is that a gathering of such dust devil tracks is seen so rarely in other MRO high resolution photographs. I look at a lot of MRO pictures, and though dust devil tracks are not rare, most images don’t show this many. Apparently, there are specific conditions on Mars that cause a lot of tracks to appear in specific locations, either because atmospheric conditions create a lot more dust devils, or the ground conditions allow the tracks to become more visible.
