Scientists: Martian topography in one region suggests the past existence of lakes and river networks, but not a large single ocean

3:53 pm

Based on a just published paper, scientists using orbital topography data and imagery have concluded that more than three billion years ago on Mars ancient rivers in the transition zone between the southern cratered highlands and the northern lowland plains fed into numerous lakes in the lowlands, not a single large ocean as some scientists posit.

From their abstract:

The northern third of Mars contains an extensive topographic basin, but there is conflicting evidence to whether it was once occupied by an ocean-sized body of water billions of years ago. At the margins of this basin are the remnants of deltas, which formed into water, but the size and nature of this water body (or water bodies) is unclear, and detailed investigations of different regions of the basin margins are necessary.

In this study, we use high-resolution image and topographic datasets from satellites orbiting Mars to investigate a series of water-formed landforms in the Memnonia Sulci region, set along the boundary of Mars’s northern basin. These landforms likely formed billions of years ago, providing evidence for ancient rivers and lakes in this region. The geologic evolution of these rivers and lakes was complicated, likely influenced by water-level fluctuations, changes in sediment availability, and impact cratering. Our topographic analysis of these rivers and lakes suggests that they terminated in a series of ancient lake basins at the boundary of Mars’s northern basin, rather than supplying a larger, ocean-sized body of water. [emphasis mine]

Overview map

The Memnonia Sulci region is in the cratered highlands just south of the Medusae Fossae Formation, the largest volcanic ash deposit on Mars. The region of study in it is marked by the blue dot in the overview map to the right.

The study does not preclude the possible existence of a northern ocean on Mars, but it says that at least in this region at the equator, it did not exist. Instead, the various river valleys drained into separate smaller and relatively short-lived lakes.

Pushback: Professor, fired for having an opinion, sues university

12:10 pm

Gregory Manco
Gregory Manco, a fighter for free speech

Don’t comply: Professor Gregory Manco, fired a professor at St. Joseph’s University because he publicly expressed some opinions, has now sued the university and six individuals (including one student whom Manco never even taught) for discrimination, breach of contract, negligence, defamation, slander, and civil conspiracy.

Manco’s story was covered twice previously in my daily blacklist column, first in March 2021 when he was suspended for having opinions the university did not like, and then in August 2021 when the university fired him for having those opinions.

Manco however is not bowing to this ill treatment. His complaint outlines in detail how the college and these individuals conspired to destroy him through false statements and slanders. He is demanding a full financial recovery for the loss of income plus compensatory and punitive damages for their actions.

Read his complaint, especially the section outlining the facts of the case. It is most revealing, especially at the level of viciousness and dishonest against Manco by these individuals, documented by screen captures of emails and texts. Worse, it appears the university in public endorsed their lies, despite that fact that its own investigation had exonerated Manco on all counts.

Based on the facts of the case, Manco is likely to win, and win big. The best part of his suit is that he is demanding damages from the actual individuals who defamed him, not just the university itself. People who nonchalantly slander others for the purpose of destroying them must be made to realize that this bad behavior will only result in their own destruction. Only then will these blacklisting tactics cease. Kudos to Manco for fighting back.

Curiosity images the Martian version of a cave formation

10:00 am

An helictite on Mars?
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken today by Curiosity’s Mars Hand Lens Imager (MAHLI), a camera designed to get close high resolution images of very small features on the surface.

The Curiosity image site does not provide a scale, but MAHLI, located at the end of the rover’s robot arm, is capable of resolutions as small as 14 microns per pixel. Since a micron is one thousandth of a millimeter, and the original image was 1584 by 1184 pixels in size, that means the entire image is likely only slightly larger than 18 to 25 millimeters across, or slightly less than an inch.

This feature, which closely resembles a cave helictite, is thus about a quarter inch in size. Helictites, which in caves often resemble wildly growing roots, are nonetheless made of calcite, not organic material. They grow wildly because the water is being pushed out from their center is under pressure, so that as it drips away from the formation it leaves its calcite deposits randomly, causing the formation to grow randomly.

MAHLI also took what looks to be an infrared or heat image of the formation, which appears to show that the tips of the branches are at a different temperature, I think cooler, than the rest of the formation.

While seeping water causes helictites on Earth, what formed this thing on Mars is beyond my guess. It sure looks cool however.

Space spat between Biden and Rogozin over Russian invasion of Ukraine

9:23 am

Yesterday saw harsh words expressed by both President Biden and the head of Roscosmos, Dmitry Rogozin, concerning the partnership of the two countries at ISS, with Biden imposing sanctions and noting these will specifically harm Russia’s space industry, and Rogozin responding by threatening to dump ISS on either a U.S. or European city.

In Biden’s statement, he said, “We estimate that we will cut off more than half of Russia’s high-tech imports, and it will strike a blow to their ability to continue to modernize their military. It will degrade their aerospace industry, including their space program,”

Rogozin’s response came in a series of tweets on Twitter, with his most bellicose statements as follows:

Do you want to destroy our cooperation on the ISS?

This is how you already do it by limiting exchanges between our cosmonaut and astronaut training centers. Or do you want to manage the ISS yourself? Maybe President Biden is off topic, so explain to him that the correction of the station’s orbit, its avoidance of dangerous rendezvous with space garbage, with which your talented businessmen have polluted the near-Earth orbit, is produced exclusively by the engines of the Russian Progress MS cargo ships. If you block cooperation with us, who will save the ISS from an uncontrolled deorbit and fall into the United States or Europe? There is also the option of dropping a 500-ton structure to India and China. Do you want to threaten them with such a prospect? The ISS does not fly over Russia, so all the risks are yours. Are you ready for them?

Meanwhile, it isn’t Russia’s space industry that will suffer the most from this invasion, but Ukraine’s. For example, the American company Launcher, which has had a software team in the Ukraine, has moved most of that team to Bulgaria for their safety.

As a precaution given the escalating political situation, during the last few weeks, we successfully relocated our Ukraine staff to Sofia, Bulgaria, where we opened a new Launcher Europe office. We also invited their immediate family to join them in this move and funded their relocation expenses. We continue to encourage and support five of the support staff and one engineer who decided to remain in Ukraine.

The company’s press release makes it clear that it is no longer dependent in any way with facilities in the Ukraine.

Launcher’s actions will not be the last. Expect all Western commercial efforts linked to the Ukraine to break off ties in order to protect their investments. Moreover, if Russia should recapture the Ukraine entirely, it will likely not give much support to its space industry, as Roscosmos has developed its own Russian resources in the past two decades and will likely want to support those instead.

Thus, the expected destruction of that country’s aerospace industry by Russia’s invasion proceeds.

Stratolaunch’s Roc successfully completes 4th test flight

9:02 am

Capitalism in space: Stratolaunch’s Roc airplane, the largest ever flown, successfully completed its 4th flight yesterday, testing for the first time the retraction and extension of its landing gear.

The flight lasted one hour and forty-three minutes.

The company is now aiming to begin full operations in the second half of ’23, when it hopes it will also be dropping versions of its Talon-A test vehicle from the bottom of Roc to perform hypersonic tests for the military as well as commercial companies.

SLS launch delayed again

8:54 am

As expected, NASA announced yesterday that it will be unable to launch its SLS rocket on its first unmanned test flight in April, as the agency had hoped, and is now evaluating a May launch date instead.

“April is not a possibility. We’re still evaluating the tail end of May,” said Tom Whitmeyer, NASA’s deputy associate administrator for exploration systems development. “But I want to be really careful once again, being straightforward with you. You know, we really need to get through this next few weeks here, see how we’re doing.”

The next possible windows for launch are from May 7-21, June 6-16 and June 29-July 12.

March 16th is still being targeted for the rocket’s full launch countdown dress rehearsal. Since the agency has said it will need about a month to assess the results of that dress rehearsal, the May launch window is exceedingly unlikely. Based on the slow pace NASA has set throughout this entire project, I predict that the launch will not occur before June, with the excellent chance it will be delayed to the summer. And this is assuming the dress rehearsal goes perfectly.

Today’s blacklisted American: 9-year-old boy denied kidney transplant because donor hasn’t gotten COVID jab

They’re coming for you next: A nine-year-old boy has been denied a kidney transplant by his hospital because his donor, who also happens to be his father, has not gotten any COVID shots.

Nine-year-old Tanner Donaldson suffers from stage 5 chronic kidney disease and urgently needs a kidney transplant. Miraculously, his father, Dane, is a perfect match to donate one of his kidneys. In early 2018, Cleveland Children’s Hospital approved the transplant. Shockingly, however, the hospital is now denying Tanner’s transplant following the execution of a “cruel, illogical, and unscientific” policy that demands the donor—but not Tanner—to be vaccinated against COVID-19.

Both the father and the child have gotten and recovered from the Wuhan flu, and thus have natural immunity, which is one reason the father doesn’t want to get the jab. Furthermore, he considers the risks of the shot far outweigh its benefits. As the family’s lawyer noted in a letter to Jane Jankowski, Interim Director of the Cleveland Clinic Center for Bioethics that made the decision blocking the transplant operation:

The deadly impact of Russia’s Ukraine invasion on commercial space, on ISS, and beyond

11:50 am

The International Space Station
The Russian invasion might be signaling the end of the ISS partnership.

Though the international ramifications of the invasion of the Ukraine by Russia in the past week will be far reaching and hard to predict, we can get a hint by reviewing the impact on Russia’s long-standing partnership on ISS as well as the effect the invasion will have on a number of commercial enterprises dependent on both Russian and Ukrainian space rocketry.

The International Space Station

All signs so far from the western partners on ISS indicate that they are guardedly hopeful that the cooperation with Russia will continue unimpeded. According to two stories (here and here) describing a panel discussion today at George Washington University Space Policy Institute, state department officials expressed complete confidence that the partnership at ISS will continue without interruption, as it did in 2014 when Russia invaded the Crimea, taking it from the Ukraine. From the first link:

Ingenuity update: Dust storm caused issues; 20th flight upcoming

9:43 am

Overview map
Click for interactive map.

According to the Ingenuity engineering team in an update today, the Mars helicopter is getting ready for its 20th flight, scheduled for no earlier than today, even as the team successfully dealt with dust that settled on the helicopter’s various parts prior to flight 19.

The dust storm did, however, leave the Ingenuity team with two additional challenges to deal with: a dirty navigation camera window and dust in the swashplate assemblies.

Comparing navigation camera images taken before and after the dust storm revealed that the storm deposited debris on the ground-facing navigation camera window, specifically around the periphery of the camera’s field of view. Debris on the navigation camera window is problematic because Ingenuity’s visual navigation software may confuse the debris with the actual ground features that it tries to track during flight, which can cause navigation errors. Fortunately, Ingenuity’s software provides a tool for dealing with this issue: The team can provide an updated image mask file that tells the visual navigation software to ignore certain regions of the image. The operations team made use of this feature and performed an image mask update late last month.

The dust storm also deposited dust and sand in Ingenuity’s swashplate assemblies. On Mars as well as on Earth, a helicopter’s swashplates are very important because they control the pitch (angle from horizontal) of the rotor blades, which is essential for stable and controlled flight. Ingenuity’s swashplate issue was first detected when the rotorcraft reported a failure during its first automated swashplate actuator self-test since the dust storm on Jan. 28, 2022 (Sol 335 of the Perseverance mission). Data revealed that all six swashplate servo actuators were experiencing unusual levels of unusual levels of resistance while moving the swashplates over their range of motion.

The engineers subsequently tested a procedure, planned before launch, for cleaning the swashplates, and found that it worked.

The data from that activity showed a significant improvement – a reduction in servo loading, so the team followed it up with seven back-to-back servo wiggles on Sol 341. Remarkably, by the end of that activity, Ingenuity’s servo loads appeared nearly identical to nominal loads seen prior to the dust storm.

After dealing with both dust issues, flight 19 proceeded successfully, as planned.

The overview map above shows the present location of Perseverance as the red dot, the present location of Ingenuity by the green dot, and the approximate landing site for the helicopter’s 20th flight by the black dot. The tan dotted line shows Perseverance’s planned route.

Perseverance itself has been traveling fast since Ingenuity’s last flight on February 9th, almost completely retracing its steps to return almost to its landing site.

Viet View – In The Year 2525

An evening pause: This is a cover of the classic Zager and Evans 1960s song. It also cleverly uses material from numerous post-1980s sci-fi movies to match the words. Overall, those movies portray a brave new world future (as Huxley saw it), humorless, soulless, and inhumane — as does the song.

Trudeau’s grab of the bank accounts of his political enemies might have crashed the Canadian banking system

4:56 pm

The decision by the Trudeau government in Canada to freeze the bank accounts of the truck convoy protesters and their supporters now appears to have backfired monumentally, so much so that it has threatened to possibly crash the Canadian banking system as people apparently began rushing to withdraw their money out of fear it will be taken from them.

What might seem like a great tool for political punishment has long term consequences, especially if people start withdrawing their money and/or shifting the placement of their investments to more secure locations away from the reach of the Canadian government. Considering the rules of fractional banking and deposits, it doesn’t take many withdrawals before the banks have serious issues.

Is this happening? It appears it might be, though the Trudeau government and banks appear to be trying to hide it. The first indicator was the sudden several hour shut down of all web access to Canada’s five major banks shortly after the bank freeze was announced. The available data, though limited, suggested that the banks had suddenly experienced a run of customers withdrawing money, and shut down access temporarily to try to stem the tide.

The next indicator is the decision yesterday to unfreeze almost all of those bank accounts. That decision, along with Trudeau’s announcement today that he is revoking his emergency powers, suggest that the banks had put pressure on him to act, because the withdrawals had not ceased, and if he didn’t act the entire system would have crashed.

Whether Trudeau’s actions will end the panic however is quite unclear. I know that if I had any cash in a Canadian bank I would right now be looking to put at least some of it elsewhere. The same thought applies to American banks, as their recent effort to shut down accounts of conservatives like Mike Lindell suggests that many banks will go along with a similar order by the Biden administration. And with an American truck convoy just now gearing up and heading for Washington, no one should be surprised if such a draconian action is just over the horizon.

Dry barren ground in Martian northern lowlands?

Dry barren ground in the Martian northern lowlands?
Click for full image.

Today’s cool image is intriguing because of what appears to not be there, rather than what is there. The photo to the right, cropped and reduced to post here, was taken on November 3, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

At first glance it appears to show a very dry, barren surface. At its base are many parallel grooves running from the southwest to the northeast. On top of these grooves are several more recent crater impacts, as well as several patches of higher bedrock that appears to have been hard enough to resist whatever erosion process caused the groves.

Yet, based on the overview map below, the location of this photo should not be dry and barren, but instead home to a near-surface ice sheet covering everything.

Pushback: Federal court grants injunction against United Airlines COVID shot mandate

1:49 pm

United Airlines: Run by fascist clowns
United Airlines: Run by fascist clowns

Our body, our choice! A federal court of appeals, in a 2-1 ruling on February 18, 2022, overruled a lower court judge and granted an injunction halting any punitive action by United Airlines against any employee who refuses to get a COVID shot because of religious or medical reasons.

The Fifth Circuit judges ordered the case to go back to Pittman for review. With Pittman’s concerns about irreparable harm assuaged, he will consider remaining preliminary injunction factors and ultimately decide whether unvaccinated employees with exemptions will return to work.

In November, Pittman notably told United Airlines employees that besides their inability to prove irreparable harm, their “arguments appear compelling and convincing at this stage. … United’s mandate thus reflects an apathy, if not antipathy, for many of its employees’ concerns and a dearth of toleration for those expressing diversity of thought,” he wrote in part. [emphasis mine]

The highlighted words illustrate the general intolerance of the left in imposing its mandates these past two years. Anyone who disagrees with them is considered a non-human who deserves no rights and can be oppressed and destroyed in any way the left sees fit.

United Airlines itself demonstrated its support for this intolerance when in December 2020 it kicked a family off a plane because the parents could not keep a mask on their two year old. As I wrote then,

You must watch the video to see how crazy and irrational this is. The father is holding her with a mask covering her face, even if it isn’t on her. More important, children don’t get COVID-19. Children don’t infect others. And the child is clearly not sick. To demand a mask on her makes no sense.

The lawsuit on which the judges ruled above is part of a pushback by United employees against the company’s rules that placed more than 2,000 people on unpaid leave, with many still under United contracts that prevent them from seeking other work.

Sadly, I can’t advise my readers to choose another airline company. All the airline companies have been pretty much as oppressive as United these past two years, generally treating their passengers like cattle on the way to slaughter. It would seem there is room here for some real competition, offering employees a tolerant work environment and its customers a pleasant flight. Right now no one is doing it.

Astra releases update on February 10th launch failure

9:50 am

Capitalism in space: Astra yesterday released an update on its investigation into its February 10th launch failure at Cape Canaveral.

The update doesn’t provide any conclusions, but merely notes that the company has completed its review of all “video and telemetry” from the event, and has reconstructed a full timeline from that data.

It is now reviewing that timeline to create what engineers call “fault trees”, each a specific scenario path pointing at a possible cause of the failure. Once that cause has been identified, engineers can then propose a solution.

According to the press release, the company is already “implementing corrective actions”, though the release provides no information as to what the cause was or what they are doing to correct. It states instead that once the investigation and corrections have been completely, the company will then release a full report.

Meanwhile, it appears that at least six law firms are considering suing the company, which became a publicly traded company in July 2021. These law firms “…are seeking clients who lost significant amount of money after purchasing the stock.” The launch failure caused the stock value to drop significantly, and these law firms apparently think that the company has made false claims about its plans — such as its claim that it will eventually be launch 300 times per year — and wish to put together a class action lawsuit based on this accusation plus the drop in stock price.

Whether Astra can meet its goal of 300 launches per year is certainly at this time questionable. However, it is too soon to call the company a failure. Once it recovers from the launch failure and resumes launches — a process that for any new rocket company generally takes a few years — that stock price will certainly recover, and will rise with each successful launch.

Only should Astra fail to resume launches, or continue to fail with each launch, will the stock truly crash, and thus provide these law firms with a possible case.

At the same time, in a free society we are supposed to recognize the concept of “buyer beware.” If you buy a product or a stock, it is at your own risk. If you fail to do due diligence beforehand, your loss is your responsibility, not the company who made the product or whose stock crashed.

It appears, based on everything Astra has so far done, an investment in its stocks while quite risky has not been an unreasonable gamble, making the present case for these lawsuits somewhat weak. Time will tell however whether that changes in the future.

A thumbnail bio of George Washington

6:01 pm

An evening pause: This day, February 22nd and the birthday of George Washington, was once celebrated yearly by Americans to honor the leader of the American army in the Revolutionary War, the leader in the effort to write the Constitution, and the country’s first president who had the humbleness to step down after two terms in office.

Congress in 1971 turned that celebration into the empty “Presidents Day” holiday, that means nothing and devalues the profound importance of Washington, especially when compared to the generally mediocre individuals — with the except possibly of Lincoln alone — who followed him in that office.

I choose to celebrate Washington instead, on this the actual anniversary of this birth. The video below is a short but succinct and accurate outline of his life. It only touches the surface of the man’s unfathomable importance to American history, but it is start.

Today’s blacklisted American: Seattle school board to hold segregated meetings to pick new school superintendent

12:21 pm

Jim Crow celebrated in Seattle!
The return of Jim Crow, this time celebrated in the north, in Seattle!

“Segregation today, segregation tomorrow, segregation forever!” Issaquah School District, located in the Seattle suburbs, has decided to hold segregated-by-race meetings to pick its new school superintendent.

Issaquah School District Superintendent Ron Thiele is retiring, and the school board is looking for his replacement. The board is holding three separate meetings this month to hear from parents and guardians. But the first meeting makes it very clear who should attend.

The district bulletin lists the meeting in the following way: “Meeting for Parents/Guardians of Color and Parents/Guardians with Students of Color to Give Input About Superintendent Search, 6 p.m., Zoom.”

The other two meetings are listed this way: “Meetings for Parents/Guardians to Give Input About Superintendent Search, 9 a.m., 2 p.m., 6 p.m., Zoom.”

When challenged about this illegal policy, the board defended it as follows:

Curiosity, having successfully climbed up and out of Gordon Notch, was able to aim its navigation cameras forward yesterday and get its first views from this position across the very rocky Greenheugh Pediment to its next major goal, Gediz Vallis Ridge. The panorama above, taken by the rover’s right navigation camera, shows this view. The ridge is about 1,500 feet away, at its closest point. The rim of Gale Crater, barely visible in the haze, is about 20-30 miles away.

The overview map to the right indicates the area covered in this panorama by the yellow lines. The red dotted line indicates Curiosity’s planned future route.

Curiosity’s first view of the pediment was made in March 2020, from a point on its northern border, just beyond the top edge of the map. The panorama taken then showed what appeared to be a very treacherous and rough surface, possibly too rough for Curiosity to traverse.

According to the science team’s most recent update from before the holiday weekend, the plan had been to spend February 19-20 studying the ground, then drive a short distance yesterday to get a better view ahead.

This will give us a good vantage point to look into the valley ahead and try to scope out our future route. … We chose to drive about 10m total, in order to get the rover oriented at a good heading and parked in a good spot. We expect a similarly beautiful view from our post-drive imaging.

That view is the panorama above. Though still very rough, the ground ahead appears far more traversable than the surface seen in 2020.

Have astronomers found an exoplanet with raining metal and gems?

9:33 am

The uncertainty of science: Using data from the Hubble Space Telescope, astronomers think they have detected on a hot Jupiter exoplanet 880 light years away the formation of clouds and rain made up metals and gems.

The exoplanet is tidally locked so that one side always faces its star, which also means the temperature difference between the two hemispheres is gigantic, 5,400 degrees Fahrenheit on the dayside and about 2,600 degrees on the nightside.

Previous Hubble data showed signs of metals including iron, magnesium, chromium and vanadium existing as gasses on the planet’s dayside. But in this study, the researchers have found that on the planet’s nightside, it gets cold enough for these metals to condense into clouds.

And, just as the strong winds pull water vapor and atoms around the planet to break apart and recombine, metal clouds will blow to the planet’s dayside and evaporate, condense back on the nightside and so on.

But metal clouds aren’t the only strange phenomenon these researchers spotted on this hot Jupiter. They also found evidence of possible rain in the form of liquid gems.

While tantalizing and alien, these results have many uncertainties. What the data suggests might not be the reality. To find out more, the astronomers hope to use the James Webb Space Telescope to do more infrared observations, once it becomes operational.

China denies the rocket stage about to hit the Moon comes from its rocket

9:23 am

A Chinese official yesterday claimed that the abandoned rocket stage that will hit the Moon on or about March 4th does not come from its 2014 Long March 3C rocket that tested technology for the later launched Chang’e-5 lunar sample return mission, as suggested by amateur astronomers and an engineer at JPL.

“According to China’s monitoring, the upper stage of the rocket related to the Chang’e-5 mission entered into Earth’s atmosphere and completely burned up,” Foreign Ministry spokesperson Wang Wenbin said Feb. 21.

Space tracking data from the Space Force’s 18th Space Control Squadron suggests that 2014-065B—the international designator for the rocket stage in question—reentered the atmosphere in October 2015, a year after launch, apparently backing China’s claim.

We are thus left with a mystery. If that abandoned upper stage did not come from either a SpaceX or Chinese launch, what launch did it come from? Or is it a rocket stage at all? Could it be a previously unidentified asteroid?

There is also the possibility that it is a piece from that Chinese launch, considering how the orbital data matches so well. The stage could have split or broken apart, with one part falling in the ocean as monitored by the Space Force, and the other section now heading for the Moon. If so, China is likely denying this fact for propaganda reasons.

Northrop Grumman to launch new satellite serving mission in ’24 on Falcon 9

9:12 am

Capitalism in space: Northrop Grumman yesterday announced that it has awarded the contract for the first launch of its Mission Robotic Vehicle (MRV) — designed as a robot capable of installing multiple mission extension pods (MEP) on satellites — to SpaceX for a launch scheduled in 2024.

Once in orbit each MEP [Mission Extension Pod] is captured by the MRV and stowed for transport to the client satellite. The MRV rendezvous and docks with the client to install the MEP, which operates like an auxiliary propulsion device and uses its own thrusters to maneuver the client vehicle. Then the MRV detaches itself and moves on to grab another MEP for the next customer. The MRV is designed to stay in orbit for 10 years.

Anderson said the company expects to install as many as 30 propulsion pods over the life of the MRV.

“Our manifest for the MRV is full through mid 2026,” he said. Besides Optus, five other customers have signed term sheets to purchase mission extension pods.

Essentially, Northrop Grumman upgraded its Mission Extension Vehicle design to separate the repair section from the robot that installs it so that it is cheaper to launch everything. It can now launch multiple lighter and smaller repair pods as needed, with the robot already in orbit ready to go.

Deformed Martian craters

Deformed Martian craters
Click for full image.

Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken on September 3, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The focus of the image for the MRO science team were the wedding cake layers inside the largest crater. These layers suggest glacial ice, with the layers suggesting multiple cycles of glacial ebb and flow. Since the crater is at 43 degrees north latitude, and sits in the chaos region dubbed Protonilus Mensae, smack dab in the center of what I call Mars’ glacier country, this conclusion makes perfect sense.

To my eye, however, the most interesting feature of this photo are the many distorted craters. The overview map below shows the picture’s location, as well as several nearby very large impact craters which might have caused many secondary impacts, including the many craters at this location.

Pushback: Why are ANY parents sending their kids back to Loudoun County schools?

11:53 am

And clowns should not be running the schools
And the clowns must be fired, now!

In the past week the conservative press heralded two big legal victories against the administrative thugs running the schools in Loudoun County in Virginia who, despite no evidence that masks did anything but harm children, insisted the little kids under their supervision be muzzled eight hours a day.

First, despite an executive order by the new Republican governor, Glenn Youngkin, outlawing mask mandates in the schools, Loudoun County administrators refused to go along, even threatening to arrest children for trespass should they show up without masks. A local judge however on February 16th issued an injunction against the county’s mask mandate, preventing it from going into effect.

Second, the state’s legislature, controlled by the Republicans but with additional votes from Democrats, had quickly passed a law banning further school mask mandates, which Youngkin signed into law on February 18th.

Hallellujah! the conservative press declared. A victory against tyrants.

Virgin Galactic chairman resigns

Getting out while the getting is good: Chamath Palihapitiya, who has been chairman of Virgin Galactic’s board since it went public in 2019, suddenly announced today that he has resigned from the company.

Palihapitiya’s SPAC, or special purpose acquisition company, took Virgin Galactic public in October 2019. The company’s stock has faced volatile trading since then — climbing above $60 a share in the months ahead of Sir Richard Branson’s test spaceflight, but it recently fell below its public debut price on news of a further delay in the start of commercial service.

The now-former chairman sold his personal Virgin Galactic stake in early 2021 that was worth over $200 million at the time. But he indirectly owns about 15.8 million shares through Social Capital Hedosophia Holdings.

Like Richard Branson, Palihapitiya sold the majority of his stock when the price was high, about the time the company flew its first and only passenger flight in July, with Richard Branson on board. His exit now suggests he wants out before the company’s dismal future prospects become obvious.
