Typical but still mysterious gullies in a crater on Mars

1:40 pm

Gullies on crater interior wall

Today’s cool image to the right, cropped and reduced to post here, is of a crater in the mid-latitudes of Mars’s cratered southern highlands. The picture was taken on January 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and is actually the only high resolution image ever taken of this crater.

The gullies in the north interior wall of this crater are the reason why this picture was snapped. These gullies are very typical on the pole-facing slopes of mid-latitude Martian craters, and have puzzled scientists since they were first discovered in the late 1990s in images taken by Mars Global Surveyor. Since then, thousands have been found, almost all of which in the 30 to 60 degree mid-latitude bands where glacial features are also found. Most occur on the more shadowed pole-facing interior slopes of the craters, though at higher latitudes they are also found facing the equator.

Since their discovery scientists have puzzled over their cause, which because of their locations favoring colder temperatures suggest some form of seasonal weather factor. The most preferred hypotheses propose some interaction with water ice or dry ice, or are simply dry flows of rocky granular material. None of these hypotheses have been confirmed. Some evidence suggests they are dry flows, no water involved. Other evidence points to the influence of an underground layer of water ice.

The mystery of these gullies is enhanced by by the wider view from MRO’s context camera below, rotated and cropped to post here.

Today’s blacklisted American: Long-time scholar banned for questioning gender fluidity

11:54 am

Lysenko with Stalin
Trofim Lysenko, the APA’s new hero, preaching to Stalin as he
destroyed Soviet plant research, persecuted anyone
who disagreed with him, and caused famines that killed millions.

They’re coming for you next: John Staddon, a retired and well-published scholar and researcher, was banned from an email discussion group run by the American Psychological Association (APA) for daring to question the modern leftist concept that one can chose one’s sex.

Staddon was deleted from the listserv for allegedly violating the division’s code of conduct. “The division leadership has received complaints about some of the posts that you have sent to the division listserv,” wrote Jonathon Crystal, an Indiana University Bloomington provost and professor of psychological and brain sciences, on behalf of the division’s executive committee.

“I do not want to get into the particulars of the range of complaints over the years, but I will note that a number of members of the executive committee and others have voiced concerns publicly on the listserv in an attempt to make you aware of how readers of the list might view some of the posts,” Crystal wrote. “The executive committee views the use of the division listserv as a privilege and has voted to remove you from the listserv. I am writing to inform you that your email address has been removed from the listserv,” Crystal wrote, adding Staddon can use “other outlets to share your views.”

And what was Staddon’s evil conduct? This is what he had written:

Pennsylvania votes to severely limit governor’s emergency powers

10:48 am

Good news: Pennsylvania voters yesterday soundly approved constitutional amendments that severely limit the emergency powers of their governor, thus preventing the present and future governors from endlessly renewing such powers.

One would give the General Assembly the ability to end or extend a declared emergency without the involvement of the governor, and the other would end a declared emergency after 21 days unless extended by the General Assembly.

Previously, once the governor’s emergency powers were granted they would last for 90 days, and the governor himself could automatically renew them endlessly. This is what Democrat governor Tom Wolf has been doing for the past year. His last renewal however expires tomorrow. It is unclear whether this vote will forbid him from renewing those dictatorial powers again.

The vote however signals to all Pennsylvania politicians the hostility the voters have to these endless emergency powers and the abuse of power that has resulted.

This vote in Pennsylvania also shows us the way to freedom. Reform must come from the states, the cities, and the local school boards, not at the federal level. If enough states make changes to their laws to strengthen their voting systems to prevent what has become almost routine Democratic Party fraud, that party will lose power at all levels. If enough parents get involved in school board activities, the politicization of education for the purpose of leftist indoctrination will end.

Once these things happen, reform at the federal level might finally have a chance.

Good people have got to stop doing nothing. Time is running out. Soon it will be too late for them to do anything.

Senate revises NASA authorization to protect lunar lander award to SpaceX’s Starship

9:47 am

Even as the full Senate today begins its review of NASA’s newest authorization, the bill has been modified to grandfather in the contract award that NASA gave to SpaceX to build its manned lunar lander using Starship.

An earlier version of the bill had included language inserted by Senator Maria Cantwell (D-Washington) demanding NASA award within 30 days a contract for a second lunar lander. The modified bill extends that timeline to 60 days, but also specifically protects SpaceX’s contract award:

The Administrator shall not, in order to comply with the obligations referred to in paragraph (1), modify, terminate or rescind any selection decisions or awards made under the human landing system program that were announced prior to the date of enactment of this division.

The revised bill still puts NASA in a ridiculous position. Combined with Cantwell’s amendment, the agency will now be forced to name a second lunar lander contract within sixty days. Though it recommends doubling the money for this program ($10 billion over five years instead of ten), it does not actually appropriate it. Moreover, that new budget recommendation is still about one half of what NASA had originally requested in order to fund the construction of two lunar landers.

Not surprisingly, the entire bill [pdf] has become a pork-laden collection of spending put together without any concern for the needs for the nation. Instead, ithe 1,445-page long bill “is the proverbial ‘Christmas tree’ with a Table of Contents that alone is 15 pages” that different senators keep adding items to, making it a hodge-podge of incoherence.

The bill itself however still has to be approved by both the Senate and the House. While this should act as a corrective to make it more sane, don’t expect that. Instead, the more likely result will be that the two houses of Congress will combine together their own personal earmarks into one humongous bill.

Conscious Choice cover

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.

Discovery channel to launch contest to fly winner to space

9:19 am

Capitalism in space: The Discovery channel today announced that it is planning a contest where the winner will win an eight-day flight to ISS in partnership with the space tourism company Axiom.

The casting call on Discovery’s website says that eligibility is limited to U.S. residents or citizens, with additional requirements to be disclosed. For now, there are few other details about eligibility for hopeful astronauts applying to the Discovery show, the expected challenges entrants will face and who will serve as judges for the competition, as the series isn’t expected to start filming until next year.

It is so far unclear whether or not eligibility may include people with physical disabilities, but the casting call does include questions about your degree of impairment with physical activities. (The European Space Agency’s current astronaut process is open to candidates with physical disabilities, and the forthcoming Inspiration4 mission includes Hayley Arceneaux, who has a prosthetic limb after childhood bone cancer.)

Discovery said the series will be in eight parts and will chronicle a “grueling” process. “The series will follow each of the contestants competing for the opportunity in a variety of extreme challenges designed to test them on the attributes real astronauts need most, and as they undergo the training necessary to qualify for space flight and life on board the space station,” the channel said in a statement.

It is unclear exactly when this mission will fly, but based on its description and timing I suspect it will not be for several years, and might actually take place after Axiom installs its own module to ISS in ’24.

1st pictures from Zhurong finally released

9:09 am

Zhurong's front view
Click for full image.

Zhurong's rear view
Click for full image.

China today finally released the first images from its Mars rover Zhurong, proving that the rover landed successfully and is operating as planned. The link takes you to the website of the Chinese space agency, in Chinese. This link provides some details in English.

The two images to the right show the front and rear views from Zhurong, sitting on top of its landing. The black & white front view shows the deployed ramps that the rover will roll down when it begins it operational phase. It shows, as expected, the generally flat terrain of the northern lowlands plains of Utopia Planitia. In the distance however there appears to be distinct features, possibly the rim of a small crater. At the moment the exact location of the rover is not known, so no precise map yet exists of its surrounding terrain. This will change in the coming days as both Chinese and American scientists hone in on the rover using orbital images.

The color rear view shows that the rover’s solar panels and high gain antenna have properly deployed. While the design of Zhurong in many ways imitates the two American rovers Spirit and Opportunity (probably because China hacked into the JPL website for several years and downloaded their blueprints), it also includes several upgrades. For example, Zhurong’s solar panels unfold, providing a significantly larger surface area to gather sunlight. Both Spirit and Opportunity were somewhat hampered by the power they could obtain by their smaller solar panels. Both also experienced times when Martian dust on the panels reduced that power. Zhurong’s much larger panels will protect it better from these issues, and could allow it to survive longer on Mars.

Martian mesas made entirely of dry ice!

Dry ice mesas on Mars
Click for full image.

Time for an especially cool image! The photo to the right, taken on February 13, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and cropped and reduced to post here, shows some mesas on the south polar ice cap of Mars.

What makes those mesas cool (literally and figuratively) is that they are thought to be made up entirely of dry ice, part of the thin but permanent frozen carbon dioxide cap in the south. As explained to me by Shane Byrne of the Lunar and Planetary Lab University of Arizona, who requested this image from MRO,

[These mesas are] unusually thick compared to other dry ice mesas (a common landform in the residual ice cap). I only have the lower resolution laser altimeter data to go off for heights here (we may get a stereo pair next year), but from that it looks like 13 meters thick.

That’s about forty feet high, from base to top. In length, the largest mesa on the left is about a mile long and about 1,500 feet wide, on average. And it is made entirely of dry ice!

The red cross on the map below shows the location of these mesas on the south pole ice cap.

Today’s blacklisted American: New Apple hire fired immediately because other Apple employees considered his writings “unsafe.”

12:28 pm

The Bill of Rights cancelled at Facebook and Instagram
Doesn’t exist at Apple.

They’re coming for you next: Though Apple had actively recruited Antonio García Martínez and had reviewed his past work thoroughly before hiring him, the company fired him almost as soon as he started working for them because some of its other workers had put together a letter calling for his blacklisting because his published writings made them feel “unsafe.”

“Given Mr. García Martínez’s history of publishing overtly racist and sexist remarks,” the letter read, “we are concerned that his presence at Apple will contribute to an unsafe working environment for our colleagues who are at risk of public harassment and private bullying.”

All of this without even a hint that there’s ever been anything like such a problem at any of his workplaces.

The letter above, like the campaign against Martinez by hack press outlets like The Verge, includes a number of slanders and purposely false interpretations of what Martinez had written in his one published book, Chaos Monkeys, available on line from all ebook vendors and described on its Amazon page as

ULA successfully launches military reconnaissance satellite

10:56 am

screen capture from ULA's live stream
Screen capture from ULA’s live stream.

Capitalism in space: ULA successfully launched a Space Force military reconnaissance satellite using its Atlas 5 rocket. It also deployed two cubesats.

This was the first Atlas 5 launch in 2021. The satellite has now been deployed into its transfer orbit taking it to its final geosynchronous orbit.

The leaders in the 2021 launch race:

15 SpaceX
12 China
7 Russia
2 Rocket Lab
2 ULA

The U.S. now leads China 21 to 12 in the national rankings. Note also that though we are still six weeks short of the year’s halfway point, the U.S. is already more than halfway to its total from all of 2020, 40 launches. If this pace continues the U.S. has a good chance of reaching launch totals that were only routine during the mid-1960s, at the height of the beginnings of the space race.

NASA gives an American the seat on Dragon flight that it had been holding for Russian

10:15 am

NASA yesterday announced that it has added an American astronaut to the next manned mission to ISS, set for October.

NASA said that Kayla Barron will join the Crew-3 mission, launching on a SpaceX Crew Dragon spacecraft scheduled for launch no earlier than Oct. 23. Barron joins NASA astronauts Raja Chari and Tom Marshburn, and European Space Agency astronaut Matthias Maurer, who had been assigned to Crew-3 last December.

The Crew-3 mission will relieve the Crew-2 astronauts who arrived at the station on another Crew Dragon spacecraft April 24. The four Crew-3 astronauts will remain on the station for a six-month stay.

The space agency had been holding that seat open for a Russian, as part of its long term barter arrangement whereby in exchange for flying Americans on Soyuz capsules, Russia flies Russians on American spacecraft. That arrangement had been used repeatedly when the shuttle was flying, but since its retirement the U.S. has been forced to buy its seats on Soyuz as it had nothing to offer in exchange.

With the arrival of SpaceX’s Dragon capsule however NASA has been trying to get the Russians to renew that arrangement. And though an American, Mark Vande Hei, flew for free on a Soyuz last month, the Russians have as yet refused to assign their own astronaut to this upcoming October flight, despite months of negotiations. It appears NASA decided it could wait no longer, and filled the seat with its own astronaut.

In fact, the announcement by Roscosmos on May 13th that the next two Soyuz launches to ISS will carry two commercial passengers each means that Vande Hei cannot return on a Soyuz until next year. The seat he would have used to come home now must be used by these tourists, meaning his mission will now be extended to last for as much as a full year or more.

Unless of course NASA decides to bring him home on a Dragon capsule instead.
