A confused river of ice on Mars
Click for full image.
Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on March 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what MRO’s science team labeled a “Landform in Source Region of Harmakhis Vallis.”
They are being very correct and careful with that label. The landform here is quite clearly reminiscent of a glacier, but because they don’t yet have confirmation of its watery nature, as good scientists they can’t call it that.
I however am a mere journalist, so I am free to speculate more wildly. Sure looks like glaciers to me, the ice flowing downhill from the left to the right and flowing around that central mound.
The overview map below gives a wider context, but also makes the behavior of the glaciers here far more puzzling.

Today’s blacklisted American: George Mason University to blackball whites and men in hiring
The Civil Rights Act of 1964:
Doesn’t exist at George Mason University.
The new bigotry on American campuses: In an email sent out to his entire faculty in mid-May, George Mason University president Gregory Washington demanded that the university’s hiring practices specifically discriminate in favor of minorities and women over whites and men.
Washington further argued that the faculty at GMU do not proportionally represent the ethnicities of the student body or the surrounding region. A vision of diversity and inclusion in hiring “is a recognition of the reality that our society’s future lies in multicultural inclusion,” he said in his email.
This begins by redefining “best” to include “lived experiences” as a top hiring criteria alongside professional aptitude, he stated. In short, “We either believe that diversity and inclusion can improve our performance, or we don’t,” Washington stated.
Consequently, Washington recommended hiring based jointly on teaching ability, research achievements, and openness to diversity. The result, he argued, will support minorities who don’t have equal access to opportunities for success.
To really get a flavor of Washington’s discriminatory recommendations you need to read his whole email. » Read more
Japanese scientists complete inventory of Ryugu asteroid samples
In a press conference yesterday the Japanese space agency JAXA announced that scientists have completed their inventory of the samples brought back from the asteroid Ryugu by the Hayabusa-2 spacecraft, and are now ready to begin distributing those samples to scientists around the world for more detailed research.
JAXA has cataloged the soil samples brought back by Hayabusa 2 last December, by size, color and shape. From now, 269 researchers from 14 countries, including Japan and the United States, will conduct an in-depth analysis of the soil’s structures and components over the course of about a year.
As expected, the inventory found the samples had a large amount of hydrogen, oxygen, and carbon atoms. Even before Hayabusa-2’s arrival, Ryugu had been catalogued as a “hydrated” asteroid, which means it was thought to contain a lot of hydrogen and oxygen, the basic elements of water. The inventory has now confirmed this.
Japan passes law protecting property rights in space
Japan’s legislature on June 15th approved a new law designed to protect the ownership of the resources private entities extract for profit in space.
Japan’s legislation is similar to provisions in the Commercial Space Launch Competitiveness Act, passed by the U.S. Congress and signed into law by President Obama in 2015. That law grants U.S. companies rights to resources that they extract, but not property rights to celestial bodies, which would run afoul of the Outer Space Treaty. Luxembourg and the United Arab Emirates have since passed similar legislation.
All four countries are signatories of the Artemis Accords, which endorses the ability to extract and use space resources. “The Signatories affirm that the extraction of space resources does not inherently constitute national appropriation under Article II of the Outer Space Treaty, and that contracts and other legal instruments relating to space resources should be consistent with that Treaty,” the accords state.
Both Russia and China oppose such legislation, as well as the Artemis Accords, which have now been signed by eleven countries.
What this growing alignment of opposing sides means for future space operations by private companies is unclear, though it suggests these two countries will not honor those private property rights, which in turn suggests this legal disagreement is eventually going to lead to physical conflict in space.
China’s Long March 2C rocket launches three military satellites
China today used its Long March 2C rocket to launch three military reconnaissance satellites into orbit.
The rocket’s first stage uses highly toxic hypergolic fuels, and is expendable. Since it is launched from the interior of China, that stage always crashes on land, sometimes near residential areas. No word on where it crashed today.
The leaders in the 2021 launch race:
19 SpaceX
18 China
8 Russia
3 Northrop Grumman
The U.S. still leads China 27 to 18 in the national rankings.
U2 – Mysterious Ways
An evening pause: Stay with it for what is made to appear as an impromptu addition of an audience member dancing. She steals the show.
It might be improvised, but if it was, it happened repeatedly, at different places, sometimes with a girl that looks identical to this one. I suspect they pre-planned it each time, but no matter, it works quite well this time, for sure.

Today’s blacklisted American: NY accounting program for high school students bans whites
The Civil Rights Act of 1964: unilaterally repealed by
the universities in New York.
Blacklists are back and New York’s got ’em! Until Campus Reform revealed its bigoted discriminatory policy, a New York accounting program for high school students specifically excluded whites from applying.
The first link above includes a screen capture of the program’s original application requirements, which included five categories, (1) Hispanic or Latino, (2) Black or African American, (3) Native Hawaiian or Pacific Islander, (3) Asian, (4) Native American or Alaska Native, (5) Two or More Races.
Notice what’s missing? If you are simply white and thus do not fall into these categories, you must go to the back of the bus. For example, my kids (had I any) would be Jewish, white, and of European descent, and thus under these definitions would be forbidden to even apply to the program. And the only reason they would be rejected would be because of their race and ethnicity, a criteria that is a blatant violation of so many anti-discrimination laws passed since the 1960s it boggles the mind.

New data confirms lack of dark matter in one galaxy
The uncertainty of science: Astronomers have strengthened their evidence that one particular nearby galaxy is completely devoid of dark matter, a situation that challenges the existing theories about dark matter which suggest it comprises the bulk of all matter in the universe.
The astronomers had made their first claim that this galaxy, NGC 1052-DF2, lacked dark matter back in 2018, a claim that was strongly disputed by others.
The claim however would only hold up if the galaxy’s distance from Earth was as far away as they then estimated, 65 million light years (not the 42 million light years estimated by others). If it were closer, as other scientists insisted, then NCC 1052-DF2 likely did have dark matter, and the theorists could sleep at night knowing that their theory about dark matter was right.
To test their claim, the astronomers used the Hubble Space Telescope to get a better, more tightly constrained estimate of the distance, and discovered the galaxy was even farther away then previously believed.
Team member Zili Shen, from Yale University, says that the new Hubble observations help them confirm that DF2 is not only farther from Earth than some astronomers suggest, but also slightly more distant than the team’s original estimates.
The new distance estimate is that DF2 is 72 million light-years as opposed to 42 million light-years, as reported by other independent teams. This places the galaxy farther than the original Hubble 2018 estimate of 65 light-years distance.
So, does this discovery invalidate the theories about dark matter? Yes and no. The theories now have to account for the existence of galaxies with no dark matter. Previously it was assumed that dark matter was to be found as blobs at the locations of all galaxies. Apparently it is not.
However, the lack of dark matter at this one galaxy does not prove that dark matter is not real. As noted by the lead astronomer in this research,
“In our 2018 paper, we suggested that if you have a galaxy without dark matter, and other similar galaxies seem to have it, that means that dark matter is actually real and it exists,” van Dokkum said. “It’s not a mirage.
Ah, the uncertainty of science. Isn’t it wonderful?
China and Russia outline long term plans for building joint lunar base
The governments of China and Russia yesterday announced their long term roadmap for building a joint manned lunar base on the Moon, what they have labeled the International Lunar Research Station (ILRS).
The graphic to the right, rearranged by me from the PowerPoint slides released by the two governments, shows the overall plan.
The first phase, starting now and running through ’25, will involve six already planned unmanned missions by both countries, three each. Of the three Chinese unmanned missions, Chang’e-4, Chang’e-6, and Chang’e-7, the first is already operating on the Moon, as it includes the Yutu-2 rover. Based on China’s recent track record, it would be reasonable to expect the other two Chang’e missions to fly as planned.
Of the three Russian missions, Luna 25 is scheduled to launch later this year, making it the first all-Russian-built planetary mission in years and the first back to the Moon since the 1970s. The other two Russian probes are supposedly under development, but based on Russia’s recent track record in the past two decades for promised space projects, we have no guarantee they will fly as scheduled, or even fly at all.
The second phase, running from ’26 to ’35, will begin construction, though the details are vague.
The third phase, when China & Russia say they will begin full operations in ’36, is even more vague, merely stating the objective of human “lunar research and exploration”.
The pace matches well with the typically slow pace of these kind of government programs. It not only matches with the pace that China has shown in its entire manned program, with manned missions sometimes separated by years, it also matches the sluggish long term roadmap that NASA has put forth for its own Artemis program on the Moon. It also fits with Russia’s recent pattern, which is to repeatedly announce big projects and goals, with little actual execution to follow.
At first glance the plan suggests that we are in a new space race between the United States and its national partners in the capitalist west and the authoritarian governments of China and Russia. That may be so, but I think the real race will be between the government programs in China, Russia, and the U.S. and the efforts by private commercial companies aiming to make profits in space. And if you ask me to bet on who will get more accomplished faster for less money, I will hands down put my money on those private companies. The more profit they make, the faster they will push to move forward, and will quickly leave these sedate government programs in the dust.
Russia announces it is shifting its manned operations on ISS to yearlong missions
According to Dmitry Rogozin, head of Roscosmos, Russia is changing the standard length of a crew stay at ISS from six months to a full year, beginning with the flight in which the crew will help film a commercial movie on ISS in October.
Then-Head of the Gagarin Cosmonaut Training Center Pavel Vlasov earlier said that two members of the Soyuz MS-18 spacecraft, Pyotr Dubrov and Mark Vande Hei, would stay in orbit longer than six months to help shoot a film Vyzov (Challenge). He also said that crew commander Oleg Novitsky would return to Earth in October aboard the Soyuz MS-18’s descend capsule together with the participants of the Soyuz MS-19 spacecraft’s flight (actress Yulia Peresild and film director Klim Shipenko who would be engaged in the film). Two crewmembers, cosmonaut Dubrov and NASA astronaut Vande Hei, would remain in orbit and return to Earth aboard the Soyuz MS-19 spaceship, he said.
Gaining experience at missions a year or longer, something only the Russians have accomplished, makes sense if one plans to send astronauts to Mars. I suspect however there is a second more practical reason for this change: It will free up seats on Soyuz to sell for commercial tourist flights. Russia clearly wants to compete successfully with the new American commercial manned flights that SpaceX and Axiom will be flying. This change gives them that opportunity.
Rogozin himself likely has personal financial motives. He is a co-producer on that movie, and likely will also pocket personally some of the profits from future tourist flights.
