Land of Martian slope streaks
Click for full image.
Cool image time! The photo to the right, cropped and reduced to post here, was taken on May 21, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a typical example of the many slope streaks found in the rough and very broken region north of the Martian volcano Olympus Mons, the largest in the solar system.
See this May 2019 post for a detailed explanation of slope streaks. While they appear to be avalanches, they do not change the topography of the ground, sometimes flow over rises, and appear to be a phenomenon entirely unique to Mars. While no theory as yet explains them fully, the two most favored postulate that they are either dust avalanches or the percolation of a brine of chloride and/or perchlorate in a thin layer several inches thick close to the surface. In both cases the streak is mostly only a stain on the surface that fades with time.
The location of this cool image however tells us something more about them.

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"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
Today’s blacklisted American: Chief editor on Oklahoma State U’s student newspaper forced to resign for holding a dissenting opinion
No freedom of speech allowed at
Oklahoma State University.
The new dark age of silencing: Maddison Farris, the editor-in-chief for Oklahoma State U’s student newspaper The O’Colly was forced to resign her position after she wrote an op-ed opposing any mask mandate on campus and her fellow editors ganged up on her, demanding she leave.
Two days after publication the newspaper’s editorial board issued “a correction”, essentially condemning Farris’s op-ed. They followed this up two days later with a meeting where they demanded Farris resign.
Farris submitted a letter of “forced resignation,” explaining that she had been called into a September 13 meeting with the rest of the editors and pressed into leaving her post.
Farris told Campus Reform that although most students at Oklahoma State support free speech, but there is a “portion of students who value free speech until it makes them uncomfortable.”
More details here. It appears Farris wrote her op-ed as a result of being forced to leave a classroom because she would not wear a mask, even though the law apparently allows her to do so.

Italy switches from Arianespace to SpaceX for launch contract
Capitalism in space: Because of the two recent launch failures of Arianespace’s Vega rocket (built mostly in Italy), the Italian space agency (ASI) has decided to take the launch of an Earth observation satellite from Arianespace and award the launch contract instead to SpaceX.
The article at the link describes in detail the history and politics that make this decision significant. Essentially, because Arianespace in the past decade has failed to meet the challenge of SpaceX, so that its launches continue to be more expensive, this government-subsidized business has tried to force nations in the European Space Agency (ESA) to use Arianespace rockets via political agreements.
With this decision Italy is defying that pressure, which in turn is going to increase the pressure on Arianespace to finally step up its game, or die from lack of business. For example, when the ESA agreed to have Arianespace build its next generation rocket, the Ariane 6, it failed to require it to be reuseable. The Ariane 6 rocket was therefore designed as an expendable rocket, which meant that right from the start it could not compete with SpaceX’s Falcon 9. It has therefore failed to win launch contracts.
Expect the Ariane 6 to continue to fade as the years pass, simply because the bureaucrats in ESA and Arianespace refused to take their competition seriously.
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.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“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.
All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.
Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.
William Shatner to fly on next New Shepard suborbital flight
Capitalism in space: Blue Origin today announced that William Shatner will join three other passengers on its next New Shepard suborbital flight, presently scheduled for October 12th.
Today, Blue Origin announced actor William Shatner and Audrey Powers, Blue Origin’s Vice President of Mission & Flight Operations, will fly on board New Shepard NS-18. They will join crewmates Chris Boshuizen and Glen de Vries for the flight which lifts off from Launch Site One on October 12.
Powers appears to be flying as both a reward for her work at Blue Origin and as a engineer to observe the operation of the spacecraft.
Shatner, an actor for more than six decades and most famous for his role as James T. Kirk in Star Trek, is 90 years old, which will make him the oldest person to ever fly into space.
BeppiColombo’s first images of Mercury
Click for full image.
This past weekend the European/Japanese duel-orbiter mission made its first flyby of Mercury, taking its first images of that planet.
The photo to the right is one example, cropped and reduced slightly to post here. It was taken by the spacecraft’s monitoring cameras, designed for engineering purposes, which means the resolution is not very high and the camera is positioned so that parts of the spacecraft were visible in each shot. For example, the white strut in the lower right is the spacecraft’s magnetometer boom, which also was used to gather data during the flyby.
Still, the photos demonstrated that the spacecraft is pointing correctly and on course. It will complete five more Mercury fly-bys before going into orbit in 2025.
The next flyby will occur in June ’22.

NASA issues request for commercially-built spacesuits for its Artemis program
Capitalism in space: After more than a decade of delays in building its own in-house next generation spacesuits, NASA this week issued a request for proposals from the commercial space industry for new spacesuits for its Artemis program.
Bidders can use the technology NASA developed for [its unfinished upgraded spacesuits] in its proposals, or they can use their own designs, the document states. The suits must be able to meet a variety of requirements, including up to six spacewalks on the lunar surface during initial Artemis Moon missions. They must also be made of materials such that less than 100 grams of lunar regolith is brought back into the “cabin environment” after each spacewalk on the Moon. NASA plans to award a contract by next April.
The plan is comparable to what NASA has been doing across the board now for the last three years, buy the product from the commercial sector in a fixed price contract. The company that builds the suits will retain ownership of the design, and can make money selling its use to others.
This policy approach continues the agency’s acceptance of almost all the recommendations put forth in my 2017 policy paper, Capitalism in Space, a free pdf download.
It also likely means NASA might finally get the spacesuits it needs for future lunar missions quickly and at a reasonable cost, something the agency itself has been unable to do.

Inactive volcano vent on Mars
Click for full image.
Cool image time! The photo to the right, cropped, reduced and annotated to post here, was taken on July 30, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The left image shows a pit that the scientists label a “vent” near the giant volcano Pavonis Mons. The right image is identical, except that I have brightened it considerably to bring out the details in the shadowed area.
As you can see, this pit is filled, and does not appear to have any existing openings into more extensive underground passages.
The white dot on the overview map on the right shows this vent’s location, to the south of Pavonis Mons, and in line with the giant crack that splits three of Mars’ four largest volcanoes. The vent is even aligned the same as that crack, from the northeast to the southwest. The black dots mark the locations of the many cave pits found in this region.
Was this a volcanic vent? If you look at the full image you will see that this pit aligns with a shallower pit to the southwest, with a depression linking the two. Visually this suggests this is a faultline which in turn makes for a good outlet point for lava flow.
Though the data suggests this is a volcanic vent, that supposition is as yet unproven. The full image does not show much evidence of a flow from the pit, which suggests instead that we are merely looking at a spot where the ground cracked along fault lines.
The Arizona election audit found significant issues that could easily have changed the final result
Click for full graph.
Now that the election audit of the biggest county in Arizona is complete and released, it is necessary to look at what it found. This article does a nice job of summarizing the audit’s conclusions, which in total make it very clear that a lot of corruption and incompetence occurred in the 2020 election in Maricopa County, some of it possibly bordering on outright election fraud.
The graph to the right, from the audit, illustrates this. In twenty-two different categories the audit found votes that should not have been counted because they were illegal or invalid in some manner. Of those, seven categories described illegal or invalid votes totaling more than 53,000 votes, five times the 10,457 vote margin of Joe Biden’s victory in the state.
Does this meant Trump won Arizona? Who knows? The audit did not determine the number of illegal or invalid votes that went to either candidate. What it did find, however, is that the entire voting system is corrupted and untrustworthy, and must be fixed.
The audit results have also revealed why the election officials in Maricopa County have been fighting this audit from day one. They clearly knew the election system was untrustworthy, and wanted to hide this fact, either to protect themselves from prosecution or to maintain their ability to defraud the voters.
Today’s blacklisted American: Louisiana health company to punish employees with unvaccinated spouses
Death camps are coming for the unclean unvaccinated.
They’re coming for you next: A Louisiana hospital system, Ochsner Health Systems, has informed its employees that they will be fined $100 per salary check for having an unvaccinated spouse on their health plan.
From the memo sent to all employees:
New in 2022: Ochsner is implementing a new Spousal COVId Vaccine Fee as part of its 2022 medical plan premiums. This means, if a spouse/domestic partner is covered by one of our medical plans in 2022 and unvaccinated against COVID-19, a $100-per-pay-period fee will apply.
The chutzpah and irrationality of this policy is really beyond words. » Read more
Two nearby asteroids found with more precious metals than Earth’s entire global supply
Capitalism in space: Astronomers have now identified two metal-rich asteroids in orbit near the Earth, with one having a precious metal content that likely exceeds the Earth’s entire reserves.
From the paper’s conclusion:
We estimated that the amounts of Fe, Ni, Co, and the PGM present in 1986 DA could exceed the reserves worldwide. Moreover, if 1986 DA is mined and the metals marketed over 50 yr, the annual value of precious metals for this object would be ∼$233 billion.
The graphic to the right, figure 13 from the paper, illustrates the amount of precious metals available in asteroid 1986 DA, compared to the world’s entire reserves (FE=iron, Ni=nickel, Co=cobalt, Cu=copper, PGM=platinum group metals, Au=gold). From this single metal asteroid a mining operation could literally double the metal that had been previously mined on Earth.
In estimating the value of these metals, the paper tries to account for the certain drop in price caused by the flooding of so much material into the market. It is a guess however. What is clear is that this asteroid could easily serve as a supply house not for Earth but for all future colonies in space. While expensive for Earth use, for colonies already in space the material would be relatively easy to reach and mine. The colonies will already have the transportation infrastructure, since they couldn’t exist without rockets and interplanetary spacecraft. And mining and processing this asteroid material will be far easier and cheaper than trying to find it on Mars and then process it.
Asteroid 1986 DA is estimated to be about 1.7 miles across, based on radar data obtained during a close Earth fly-by in 2019. The second asteroid, 2016 ED85, appears to have a similar content from spectroscopy, but no radar data has as yet been obtained of it, so much less is known.
