Capitalism in space: Arianespace’s Vega rocket today successfully launched five satellites into orbit, completing the company’s third launch in 2021 and the second Vega launch this year.
With only three launches so far in 2021, Arianespace does not make the leader board, which is presently as follows:
26 China
20 SpaceX
12 Russia
4 Northrop Grumman
The U.S.’s lead over China in the national rankings remains 31 to 26.
Orbital data now shows that both global and regional dust storms on Mars help remove the planet’s water, allowing it to reach higher atmospheric elevations where solar radiation breaks it up and it escapes into space.
Scientists have long suspected that Mars, once warm and wet like Earth, has lost most of its water largely through this process, but they didn’t realize the significant impact of regional dust storms, which happen nearly every summer in the planet’s southern hemisphere. Globe-enveloping dust storms that strike typically every three to four Martian years were thought to be the main culprits, along with the hot summer months in the southern hemisphere when Mars is closer to the Sun.
But the Martian atmosphere also gets heated during smaller, regional dust storms, according to a new paper published August 16 in the journal Nature Astronomy. The researchers, an international team led by Chaffin, found that Mars loses double the amount of water during a regional storm as it does during a southern summer season without regional storms.
This conclusion is based on data gathers from three different orbiters during a regional dust storm in early 2019.

Cool image time! The photo to the right, rotated, cropped and reduced to post here, was taken on May 13, 2021 by the high resolution camea on Mars Reconnaissance Orbiter (MRO). It spans the entire 4.7 mile width of the southern hemisphere canyon dubbed Reull Vallis. The white arrow indicates the direction of the downhill grade
The scientists title this image “Lineated Valley Fill.” The vagueness of this title is because they have not yet confirmed that this lineated valley fill is a glacier flowing downhill to the west.
Nonetheless, the material filling this valley has all the features one expects glaciers to exhibit. Not only is the the lineation aligned with the flow, it varies across the width of the canyon as glaciers normally do. At the edge the parallel grooves are depressed, probably because they are torn apart by the canyon walls as the glacier flows past. In turn, at the center of the flow the grooves are thinner and more tightly packed, and appear less disturbed. Here, the flow is smooth, less bothered by surrounding features.
This pattern also suggests the merging of two flows somewhere upstream.
A glance at the spectacular Concordia glacier in the Himalayas near the world’s second highest mountain, K2, illustrates the similarity of this Martian feature to Earth glaciers.
Reull Vallis itself flows down to Hellas Basin, the deepest basin on Mars. As it meanders downhill along its 650 mile length it steadily gets wider and less distinct as it drops into Hellas. Along its entire length MRO has photographed numerous similar examples of this lineated fill, all suggesting that under a thin layer of debris is a thick glacier, slowerly carving this canyon out.
The overview map below illustrates these facts nicely, while further reinforcing these glacial conclusions.

The Civil Rights Act of 1964: Doesn’t exist at the University of Illinois
Genocide is coming to America: The University of Illinois at Urbana-Champaign has established a mentoring program, with financial rewards, that expressly discriminates against Asians and whites (unless the whites happen to have Latin American genes).
From the program’s own webpage:
[W]e are pleased to launch the Milliman Mentorship Program, an actuarial mentorship program for students of underrepresented minorities (Black, Latino, Native American) at the University of Illinois.
…This program is currently targeted towards students of color, early in their college career, who may be interested in a STEM-oriented career.
The webpage then lists the benefits, including financial support and additional free mentoring assistence.
As noted at the Campus Reform article at the first link, this is clearly a violation of numerous civil rights laws.

This interesting essay today describing China’s space policy and its ramifications for the United States found this most significant quote from a Chinese official:
A senior official with the CNSA’s lunar program has been reported by the Daily Beast as saying the moon and Mars (and presumably myriad other rocks out there) are the equivalent of the islands in strategic locations in the Indo-Pacific region that China contests with Japan and other countries:
The universe is an ocean, the moon is the Diaoyu Islands, Mars is Huangyan Island. If we don’t go there now even though we’re capable of doing so, then we will be blamed by our descendants. If others go there, then they will take over, and you won’t be able to go even if you want to. This is reason enough.
The fact the CCP views real estate in the solar system the same way as real estate on Earth is both instructive and amusing.
I don’t find this Chinese attitude amusing in the least. It suggests quite starkly China’s intention to claim all the land it occupies in space, in direct violation of the Outer Space Treaty. Unlike the western nations, it doesn’t care that under that treaty’s restrictions, it can’t provide property rights to its citizens. It will possess everything it gets in space, for itself.
All the more reason for the U.S. to push for the Artemis Accords, which China rejects, as those accords bypass the restrictions of the Outer Space Treaty and make property rights possible in western space settlements. In the end, every nation that establishes a base or colony in space is going to claim it, notwithstanding the Outer Space Treaty, so establishing a framework for U.S. law in those colonies is essential. The accords are a first step in doing so.
Georgia Fulton County elections chief Ralph Jones has suddenly resigned.
Jones was the man who shuttered the official count at the State Farm Arena in Fulton County on election night in November 2020, claiming falsely to reporters that a water main had broken. Everyone was sent home, the count supposedly suspended for the night.
Surveillance cameras at the arena however continued to record his actions. Jones then joined a handful of election officials to pull boxes of ballots from under a table and continue their private count, with no independent observers on hand. The videos also appear to show these election officials illegally running the same ballots through the computer tabulators repeatedly.
At the moment we do not know which candidate those ballots were for, but Fulton County is essentially Atlanta, a city entirely controlled by the Democratic Party. Like most such cities, election boards are heavily dominated by Democrats, because it is so hard to find Republicans to serve. Want to bet that a forensic audit would discover that those ballots were all for Biden, and were also manufactured falsely?
The audit ongoing in Fulton County is finding strong evidence that this supposition is true, and that these ballots were fake and designed to steal the election in Georgia for Biden.
Jones’ resignation now, during this audit, appears to confirm these allegations.

The Ingenuity engineering team today announced their plans for the helicopter’s twelfth flight on Mars, scheduled for early tomorrow.
Ingenuity will climb to an altitude of 10 meters and fly approximately 235 meters east-northeast toward the area of interest in Séítah. Once there, the helicopter will make a 5-meter “sidestep” in order to get side-by-side images of the surface terrain suitable to construct a stereo, or 3D, image. Then, while keeping the camera in the same direction, Ingenuity will backtrack, returning to the same area from where it took off. Over the course of the flight, Ingenuity will capture 10 color images that we hope will help the Perseverance science team determine which of all the boulders, rocky outcrops and other geologic features in South Séítah may be worthy of further scrutiny by the rover.
The map above shows South Seitah in the yellow oval. The yellow line marks Ingenuity’s past flights. The white line marks the path Perseverance has taken south since landing. The dashed lines mark Perseverance’s planned route.
Thus, the helicopter will be obtaining aerial photos of the region in Seitah where the scientists want to send Perseverance, in order to help them pick the best route.

The Tennes are a normal family! We must blacklist them!
They’re coming for you next: A Michigan farmer was banned from a local farmers market by the city government of East Lansing because the owners, Steve and Bridget Tennes, are Christian and had publicly stated their opposition to homosexual marriage.
The ban against their business, Country Mill Farms, was begun in 2016. Though a court quickly ruled that it was unconstitutional, the city renewed the ban in 2018 and has maintained it since, claiming the court’s ruling only applied to the 2017 season.
The logic of the East Lansing government is actually quite blatent: It believes it has the right to dictate what others can or cannot say in public, the first amendment be damned.
[C]ity officials asserted that the Tennes’ expression conflicted with East Lansing’s marriage views and its new market policy. The policy requires vendors to agree to comply with the city’s “Human Relations Ordinance and its public policy against discrimination while at the market and as a general business practice.”
It’s illegal for anyone to “make a statement which indicates that an individual’s patronage or presence at a place of public accommodation is unwelcome or unacceptable because of sexual orientation, gender identity, or expression…” among other designated classes. [emphasis mine]
In other words, East Lansing wants to forbid any dissent to the modern and very perverse sexual movement. You will not be allowed to disagree, under any condition. And if you try, you will be blackballed, censored, and squashed, as is the right of our all-knowing government.
Stalin would be proud. So would Hitler, Mussolini, and all past despots who liked killing people who disagreed with them.

Cool image time! The mosaic above was created from two photos taken on August 13, 2021 by Curiosity’s right navigation camera. It looks to the southeast, at the mountainous Martian terrain that the rover had been traveling just below for the past two months.
The overview map to the right shows with the yellow lines the approximate area covered by this mosaic. The white mountain at the top is the highest visible flank of Mount Sharp, and is beyond the right/bottom edge of the overview map. Mt. Sharp’s peak itself is not visible, as it is higher up and to the right. It is presently blocked by these mountainous foothills.
The science team probably took this image partly to provide another view of these mountains for comparison with earlier views. They can use this new data to look for changes as well as obtain better three-dimensional data.
They also took the image for the same reason I post it here. Having now climbed more than 1,500 feet from the floor of Gale Crater, Curiosity’s view is routinely spectactular. Why not enjoy it?
Mt. Sharp’s peak however is still about 13,000 feet above the rover. The climb up the mountain has just begun.
Capitalism in space: According to a Wall Street Journal story today, Boeing and NASA have decided to remove the Starliner capsule from the Atlas-5 rocket and return it to Boeing’s factory in order to do a more thorough inverstigation into the capsule’s failing valves.
This decision means that the launch of the second unmanned demo test flight of Starliner will not occur in August, and will likely be delayed several more months. NASA and Boeing just held a press conference in which they made this decision official. During that conference they said they think the moist environment at Kennedy might have caused corrosion in the valves, which caused them to stick.
I once again wonder if Boeing has any quality control systems at all. For such a serious problem — the failure of 13 valves out of 24 — to suddenly pop up just hours before launch, when they have been developing this capsule for years, and even had an extra year and a half to check the capsule out after the failures during the first unmanned demo flight in December 2019, is somewhat astonishing, and very disturbing.
Others will argue that problems like this can always appear unexpectedly in space hardware. I say hogwash. Boeing is not inventing something new with Starliner. This is a capsule, using heritage engineering first invented in the late 1950s. It should not be so hard to get this right.
Capitalism in space: Hanwah, a South Korean conglomerate, has now invested $300 million in private capital in the satellite communications company OneWeb.
U.K.-headquartered OneWeb expects regulatory approvals to complete the Hanwha transaction in the first half of 2022, bringing its total investment since emerging from bankruptcy protection in November to $2.7 billion. The startup has said it only needed $2.4 billion to fund its initial constellation of 648 satellites in low Earth orbit.
It reached that in June, after Indian telecom company Bharti Global doubled its investment to $1 billion to secure what would have been a 38.6% stake before Hanwha’s announcement. The U.K. government, French satellite operator Eutelsat and Japanese internet giant Softbank were each in line for just under 20% after making their own investments. U.S.-based Hughes Network Systems, which is supplying parts for OneWeb’s ground segment, also had a small stake.
Hanwha also wishes to build its own 2,000 satellite constellation, targeted for operation by 2030. This investment gives it access to OneWeb’s technology which it can later use.
For OneWeb, this new capital solidifies its full recovery from bankruptcy, and makes it a very viable competitor to SpaceX’s Starlink constellation.
