An evening pause: This pretty 1983 German pop song so perfectly predicts the Biden administration’s silly overreaction to the Chinese spy balloons last month, and the really dangerous consequences that could have resulted.
The lyrics of the original German version tell a story: 99 balloons are mistaken for UFOs, causing a military General Officer to send pilots to investigate. Finding nothing but balloons, the pilots put on a large show of fire power. The display of force worries the nations along the borders and the war ministers on each side encourage conflict to grab power for themselves. In the end, a cataclysmic war results from the otherwise harmless flight of balloons and causes devastation on all sides without a victor.

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, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, 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, cropped to post here, was taken on February 2, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows a strangely blobby crater in the northern mid-latitudes where glacial features are frequently found inside craters.
In this case however the glacier seems very confused. As this is in the northern hemisphere, you would expect glacial material to survive on the north-facing southern interior slopes of the crater, where there is year-round less sunlight. The mottled eroded terrain in the south part of the crater floor suggests this. However, the crater also clearly has a terraced glacier on its south-facing northern interior slopes.
Why has the glacial material survived in both places, but not in the center of the crater?
In addition, there is that strange roughly circular feature attached to the south side of the crater. What formed it? Is it a glacier on the plains surrounding the crater? Or are we looking at volcanic material?
This crater is also unique. The crater just to its southwest (partly seen in the cropped image above), is a much more typical glacial-filled mid-latitude crater, its interior material more evenly distributed and its circular rim only slightly distorted.

Correct from the start despite government censorship,
and written by many of the same doctors of the Norfolk Group
Bring a gun to a knife fight: Eight high-ranking doctors, many who were censored and blacklisted by the government and big social media outlets for daring to disagree with the government’s lockdown, masking,, and COVID jab mandates, have now issued a detailed report, dubbed the Norfolk Group report, outlining the many errors of those policies, as well as offering what the scientists call “a blueprint” for moving forward. From their introduction:
In separate chapters we summarize key background information and propose specific questions about failures to protect older high-risk Americans, about school closures, collateral lockdown harms, lack of robust public health data collected and/or made available, misleading risk communication, downplaying infection-acquired immunity, masks, testing, vaccine efficacy and safety, therapeutics, and epidemiological modeling.
We chose not to discuss economic issues, although we recognize that negative effects on the economy have long-term negative effects on public health. We have also chosen not to engage in issues regarding media handling of the pandemic, nor questions of how, when and why the SARS-CoV-2 virus originated. Public health responses to a pandemic are devised and implemented independently of viral origin.
Now available in hardback and paperback as well as ebook!
From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

Using a camera on South Korea’s lunar orbiter Danuri, dubbed Shadowcam and designed to look into the permanently shadowed craters at the Moon’s poles, scientists have taken an image that sees into the forever dark region of one such crater.
The picture to the right, released on March 13, 2023 by the Shadowcam science team, is of the crater Marvin, located about 16 miles to the east of the south pole. The pink outline indicates the area that is thought to be permanently shadowed.
The second image to the right provides a wider view of the south pole region, with the craters labeled and outlined by the green lines. The orange lines mark permanently shadowed areas. The white box indicates the approximate area covered by the Shadowcam picture. One of the candidate landing sites for Starship, as part of NASA’s Artemis program, is the eastern rim of Shackleton, essentially at the south pole itself.
Previous data suggests that ice should be found in those permanently shadowed areas, because other orbiters have detected evidence of hydrogen there. The Shadowcam picture above however shows nothing that strongly suggests the presence of ice, unless that darker flat area on the floor of the crater is ice-infused dust. If so however, it is quite ancient and solid, based on the presence of several craters within it.
The press release makes no mention of this question, probably because the scientists are still analyzing the data. This first look however suggests the ice is not there, or is in a form that is going to require a lot of processing to extract the water from it.
Japanese researchers analyzing the samples returned by Hayabusa-2 from the rubble-pile asteroid Ryugu have identified the molecule uracil, one of the four nucleobases that form the molecule RNA.
Hayabusa 2 collected 5.4 grams from two spots on Ryugu and delivered them to Earth on December 6, 2020. Early studies showed the samples contained many organic compounds. That led Oba’s group to analyze two 10-milligram samples using the same sensitive technique they had used earlier on meteorites. The technique can detect nucleic acid bases at levels down to parts per trillion in small samples.
Now, they report in Nature Communications that uracil is present at a level of parts per billion in both Ryugu samples. While this concentration is different than they’d previously found in meteorites, Oba says that might be because the parent bodies of the meteorites and of Ryugu underwent different levels of aqueous alteration and other processes. They also detected niacin (vitamin B3) as well as other organic molecules, but they didn’t find any other nucleobases.
RNA is formed from four nucleobases, uracil, adenine, cytosine, and guanine. To form DNA, the fundamental building block of life, uracil is replaced by thymine.
This data reinforces other data that suggests the formation of these essential molecules for life is relatively common and easy, at least in our solar system.

"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke
Data collected by the ground-based Very Large Telescope (VLT) in Chile before and after the impact by the DART probe in September 2022 has revealed that the rubble-pile asteroid Dimorphos is very dry, with little or no water.
[The astronomers] observed the Didymos–Dimorphos system on 11 occasions, from just before the impact to about a month afterwards. MUSE [one of VLT’s instruments] is able to split the light from the double-asteroid into a spectrum, or rainbow, of colors, to look for emission at specific wavelengths that corresponds to specific molecules. In particular, Opitom’s team searched the ejecta for water molecules and for oxygen that could have come from the break-up of water molecules by the impact. However, no evidence of water was detected. Dimorphos, at least, seems to be a dry asteroid.
You can read the paper here.
Some theories prior to DART’s impact suggested that there could be ice within some inner solar system asteroids. Finding none instead suggests that inner solar system asteroids are very distinct and different from the icy comets and asteroids either coming from or orbiting in the outer solar system.
Using the Webb Space Telescope, astronomers have detected “hot sand clouds” in atmosphere of exoplanet 40 light years away, along with evidence of water, methane, carbon monoxide, carbon dioxide, sodium, and potassium.
You can read the paper here [pdf]. The exoplanet itself appears to have some features that resemble that of a brown dwarf, or failed star, instead of an exoplanet.
Although VHS 1256 b is more on the heavier side of the known exoplanets, its gravity is relatively low compared to more massive brown dwarfs. Such very low-mass stars can only burn deuterium for a relatively short duration. Consequently, the planet’s silicate clouds can appear and remain higher in its atmosphere, where the JWST can detect them. Another reason its skies are so turbulent is the planet’s age. In astronomical terms, it is pretty young. Only 150 million years have passed since it formed. The planet’s heat stems from the recent formation process – and it will continue to change and cool over billions of years.
The sand clouds are hot, in the range of 1,500 degrees Fahrenheit.
These results were obtained as part of an early-release program from Webb, and illustrate the potential of the infrared space telescope for learning many specific details about brown dwarfs and exoplanets.

According to Russia’s state-run press, its Luna-25 unmanned lunar lander will finally be delivered to its launchsite in Vostochny in the first ten days of June 2023, after many years of delays.
The press announcement made no mention of a launch date after delivery, though according to an earlier report Roscosmos is aiming for a July 13, 2023 launch date.
The landing site on the Moon is Boguslawsky crater, as indicated by the green dot on the map to the right. If it occurs as planned, it will join three other landers now targeting 2023 lunar landings, Ispace’s Hakuto-R1, Intuitive Machines Nova-C, and India’s Chandrayaan-3, with three of four landing in the Moon’s south pole regions. The white cross marks the location of the south pole itself, on the rim of Shackleton Crater.
In anticipation of a possibly deal to save the company, Virgin Orbit officials have resumed limited operations, bringing back a small number of employees to work on crucial issues required for its next launch.
“Our first step will begin Thursday of this week, when we plan to return a subset of our team to focus on critical areas for our next mission,” Virgin Orbit said in a statement. “We are looking forward to getting back to our mission and returning to orbit.”
…Reuters reported that Virgin Orbit is working on a $200 million infusion from Texas-based venture capital investor Matthew Brown via a private share placement, citing a term sheet. Following a meeting by Virgin Orbit’s board on Tuesday, the two sides plan to close the deal on Friday, according to the non-binding term sheet, Reuters said.
Should the company resume full operations and launch again, I am certain it will not launch from the United Kingdom, at least not until the UK has fixed its launch licensing bureau, the Civil Aviation Authority, which took so long to approve Virgin Orbit’s launch from Cornwall it practically bankrupted the company.
Hakuto-R1’s planned landing site is in Atlas Crater.
The lunar lander Hakuto-R1, privately-built by the Japanese company Ispace, has now successfully entered lunar orbit in anticipation of its landing sometime next month.
Tokyo-based ispace said that its HAKUTO-R Mission 1 lander entered orbit at 9:24 p.m. Eastern March 20 after a burn by its main engine lasting several minutes. The company did not disclose the parameters of the orbit but said that the maneuver was a success.
…Entering orbit is the seventh of 10 milestones ispace set for the mission that started with launch preparations. The final three milestones are completing “orbital control maneuvers,” the landing itself and going into a steady state of activities after landing.
The spacecraft carries several payloads, the most significant of which is the United Arab Emirates Rashid rover.
If Hakuto-R1 completes its 10 milestones successfully, it will lay the groundwork for Ispace’s second Hakuto-R mission to the Moon in 2024, and an even larger lander on a third mission to follow, this time built in partnership with the American company Draper and carrying NASA payloads.
An evening pause: A slightly different pause tonight from a 1964 episode of the quiz show “I’ve got a secret.” Can you guess where the dialogue comes from that they perform at the opening of this segment, before they tell you?

They’re coming for you next: One month after administrators of Mid Vermont Christian School decided to default a game against a public high school girls team that had a boy in woman’s clothing as a player, citing safety and religious concerns, the Vermont Principals’ Association moved to ban that Christian school from all sports and sponsored activities.
Jay Nichols, the executive director of the Vermont Principals’ Association, said the organization’s 15-member executive board was unanimous in its decision. “If you don’t want to follow VPA rules, that’s fine,” Nichols said. “But then you’re just not a VPA member. It’s fairly simple. That’s really all we’re gonna really say about it.” [emphasis mine]
In its letter to Mid Vermont Christian, the VPA stated “…the school’s actions do not meet the expectations of the VPA’s 1st and 2nd policy, Commitment to Racial, Gender-Fair, and Disability Awareness and Policy of Gender Identity, respectively.”
If you want to know in detail what VPA’s 1st and 2nd policies are, you can read them here. The key quote is this:

Cool image time! The picture to the right, cropped and reduced to post here, was taken on December 24, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows erosion gullies coming down off a mountain side, just north of a massive cliff that I estimate to be around 2,000 to 3,000 feet high.
Note the north-south-trending cracks. These suggest that this entire half-mile-high cliff face is slumping downward, cracking as it does so. The cracks at the start of the high flat-topped thumb-shaped mesa near the image bottom are especially intriguing. They suggest that this entire mesa might eventually separate and give way.
There is a specific reason this cliff face is slumping, as shown in the overview map below.

Innospace, a South Korean private rocket startup, on March 19, 2023 successfully completed the first test flight of a suborbital prototype, launching from Brazil’s Alcantara Launch Center.
The rocket flew for 4 minutes and 33 seconds before falling into the designated safety zone. The engine lasted for 106 seconds, which fell short of the previously planned 118 seconds, yet its performance was stable, according to Innospace. Hanbit-TLV, the test vehicle, is a 16.3-meter (53.5-foot) single-stage rocket designed to verify the performance of a 15-ton-thrust rocket engine developed by Innospace.
The company will now develop its full-scale orbital rocket, dubbed Hanbit-Nano, “capable of carrying 50-kilogram (110-pound) payload into space, equipped with a 15-ton-thrust hybrid engine powered by solid fuel and liquid oxidizer.” A 2024 launch is the goal, possibly from a new commercial spaceport in Norway.
More information here. The rocket also carried a payload for the Brazilian military, which is why by contract Innospace officials could not release the exact altitude reached by the rocket.
An evening pause: If you have the skills, imagination, and proper tools, you can make anything. I run this at 2x normal speed, and miss nothing.

In the southwest where I live, a valley dubbed “verde” (which means “green” in Spanish) is generally a place with a somewhat persistent river with lots of lush plant life. The Verde Valley in Arizona is the perfect example, with “close to 80% of the valley’s land … national forest.”
On Mars there is also a verde valley, but the name is not descriptive in the least. The picture to the right, rotated, cropped, and reduced to post here, was taken on January 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and shows one section of the Martian Verde Vallis, draining south to north.
The dark rippled patches inside this shallow canyon are sand dunes. In fact, though MRO has not taken many high resolution images of Verde Vallis, every one shows the valley with further patches of ripple dunes. See for example this image of a section of the valley just a bit farther north.

They’re coming for you next: On February 23, 2023 the board of governors of the University of North Carolina voted to ban all requirements that applicants in hiring and admissions make statements advocating the racist political agenda of “diversity, equity and inclusion” [DEI].
The board stated the university “shall neither solicit nor require an employee or applicant for academic admission or employment to affirmatively ascribe to or opine about beliefs, affiliations, ideals, or principles regarding matters of contemporary political debate or social action as a condition to admission, employment, or professional advancement,” according to the resolution. An employee or applicant also can’t “be solicited or required to describe his or her actions in support of, or in opposition to, such beliefs, affiliations, ideals, or principles.”
According to the now-banned policy [pdf], anyone who wanted to either go to UNC as a student, or be hired or promoted there as a teacher, had to prove they had made a “positive contribution to DEI efforts.”

Cool image time! The picture to the right, cropped and reduced to post here, was taken by the Hubble Space Telescope and released today.
The galaxy JW100 features prominently in this image from the NASA/ESA Hubble Space Telescope, with streams of star-forming gas dripping from the disc of the galaxy like streaks of fresh paint. These tendrils of bright gas are formed by a process called ram pressure stripping, and their resemblance to dangling tentacles has led astronomers to refer to JW100 as a ‘jellyfish’ galaxy. It is located in the constellation Pegasus, over 800 million light-years away.
Ram pressure stripping occurs when galaxies encounter the diffuse gas that pervades galaxy clusters. As galaxies plough through this tenuous gas it acts like a headwind, stripping gas and dust from the galaxy and creating the trailing streamers that prominently adorn JW100. The bright elliptical patches in the image are other galaxies in the cluster that hosts JW100.
The image was part of a research project studying star formation in the tendrils of jellyfish galaxies.
The blob near the top of the image is another galaxy in this same galaxy cluster. It is an elliptical galaxy that also happens to have two central nuclei, caused when two smaller galaxies merged. The central regions of each have not yet merged into one.

Only a few hours after SpaceX launched 52 Starlink satellites from California, the company successfully launched two communications satellites for the Luxembourg company SES, using its Falcon 9 rocket launching from Cape Canaveral.
The first stage completed its sixth flight, landing safely on a drone ship in the Atlantic. The rocket’s two fairings completed their third and seventh flights, respectively.
The leaders in the 2023 launch race:
19 SpaceX
11 China
4 Russia
2 Rocket Lab
American private enterprise now leads China 21 to 11 in the national rankings of this year’s launches, and the whole world combined 21 to 17. SpaceX by itself is tied with the rest of the world, including other American companies, 19 to 19.
According to a tweet by Elon Musk today, Starship will be ready for its first orbital test launch in a few weeks.
Musk also noted however that SpaceX is still awaiting the FAA’s launch license, and because of this he now expects the launch in the third week in April.
Why it is taking months for the FAA to issue this license is disturbing, and suggests that under the Biden administration the feds are behaving more and more like the incompetent Civil Aviation Authority in the UK, which stonewalled Virgin Orbit’s launch for months so that the company now sits on the verge of bankruptcy.

The evil hat that Air & Space officials banned
Pushback: The Smithsonian Institution, which runs the Air & Space museum as well as other museums in Washington, D.C., has been ordered by the courts to stop violating the First Amendment, as it did when on January 20, 2023 it harassed and ejected students from a pro-life group, there as part of their participation in the annual March for Life demonstration, because they were wearing wool caps that said “pro-life” on them.
According to the consent order [pdf], the Smithsonian expressed “regret” for the event and promised to “remind all security officers stationed at NASM [National Air & Space Museum] of the rights of visitors.”
The order however does not simply accept the museum’s expression of regret. It specifically enjoins the Smithsonian and its employees “from prohibiting visitors to the Smithsonian’s National Air and Space Museum from wearing hats or other clothing with messages, including religious and political speech” and requires it to distribute the consent order to “all security officers stationed at NASM, as well as other Smithsonian personnel who interact with the public, including volunteers and museum staff, within 7 days.” It also orders the museum to tell its security officers that their behavior on January 20th was wrong.

SpaceX today successfully put another 52 Starlink satellites into orbit using its Falcon 9 rocket launching from Vandenberg Space Force Base in California.
The first stage completed its 8th flight, landing on a drone ship in the Pacific.
A second SpaceX launch today, this time from Cape Canaveral, Florida, is set to launch very shortly, so the leader board for the 2023 launch race will also change as well:
18 SpaceX
11 China
4 Russia
2 Rocket Lab
American private enterprise now leads China 20 to 11 in the national rankings, and the entire globe combined 20 to 17. SpaceX now trails the entire world, including American companies. 18 to 19.

Cool image time! The picture to the right, rotated, cropped, rotated, and sharpened to post here, was taken on November 28, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled merely as a “crater with mesa”, it gives us another example of the presence of glacial ice in the mid-latitudes of Mars.
That mesa is what planetary scientists have labeled “concentric crater fill,” a glacial feature found in numerous craters throughout the mid-latitude bands from 30 to 60 degrees latitude. The ground in the terrain surrounding the crater could be also be impregnated with ice, but based on the location as shown in the overview map below, it is just as likely to be lava.
In fact, the location of this particular crater illustrates why concentric crater fill might become the best source of ice for future colonists.

According to separate announcements just released, both India’s Chandrayaan-3 lander/rover and Intuitive Machine’s private Nova-C lunar lander have passed their last ground tests and are now ready for launch to the Moon later this year.
India’s space agency ISRO successfully completed testing of its Chandrayaan-3 lunar lander/rover in early March, completing vibration tests of the spacecraft and proving it will be able to survive the stresses during launch. The spacecraft successfully completed radiation testing in February.
ISRO is now targeting June 2023 for Chandrayaan-3’s launch.
Intuitive Machines meanwhile announced yesterday that its Nova-C lander has completed vibration testing, and is ready for launch later this year.
The map to the right shows the landing sites of these planned landers near the Moon’s south pole (indicated by the white cross), as well as Russia’s long-delayed lunar lander, Luna-25, which is now targeting a July launch.
The rocket startup Astra has now asked Nasdaq to give it an extra six months beyond the early April deadline to get its stock price above $1 in order to avoid getting delisted from the stock market.
With its share price at $0.42 upon closing Thursday, Astra Chief Financial Officer Axel Martinez wrote in a blog post that the space company formally requested on Monday another six-month window to raise the share price above $1 for 10 consecutive business days as required to stave off a delisting.
It appears the company might be considering a reverse-stock split, whereby stocks are combined with the total number reduced, thus artificially raising the stock price. Nasdaq will consider this tactic an acceptable solution, though it is also considered a last-ditch approach.
Right now Astra is no longer an operational rocket company, having discontinued its Rocket-3 rocket. It says it is developing a new rocket, dubbed Rocket-4, but whether it can get this operational before it runs out of money or gets delisted remains unknown.
Both the American company Rocket Lab and China have successfully placed satellites in orbit in the past day.
First, Rocket Lab successfully placed two Earth observation satellites for the company Capella yesterday. This was also its second launch from Wallops Island in Virginia. The company made no attempt to recover the first stage.
Next, China today used its Long March 3B rocket to place its own Earth observation satellite into orbit from its Xichang spaceport, located in the country’s northeast but far from the ocean. No word on whether the rocket’s first stage and four strap-on boosters crashed near habitable areas.
The leaders in the 2023 launch race:
17 SpaceX
11 China
4 Russia
2 Rocket Lab
For the rest of the year, I will only list the leaders with each launch update. At this moment, American private enterprise leads China 19 to 11 in the national rankings, and the entire world combined 19 to 17. SpaceX alone now trails the rest of the world combined, including American companies, 17 to 19.
These numbers will likely change later today, as SpaceX has two launches scheduled in just a few hours. One launch will place two communications satellites in orbit for the Luxembourg company SES. The other will launch another 52 Starlink satellites.
