Polygons on Mars
Click for full image.
Cool image time! The photograph on the right, cropped to post here, was taken on September 25, 2019 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and made public in its November image release. It shows the weird but very typical scalloped terrain, with its adjacent polygon pattern of fractures, found routinely in the northern lowland plains of Utopia Planitia on Mars. From an earlier captioned image from 2006 of these same features:
The scalloped depressions are typical features; a smooth layered terrain located between 40 and 60 degrees in both hemispheres. Scalloped depressions probably form by removal of ice-rich subsurface material by sublimation (ice transforming directly from a solid to a gaseous state), a process that may still be active today. Isolated scalloped depressions generally have a steep pole-facing scarp and a gentler equator-facing slope. This asymmetry is interpreted as being the result of difference in solar heating. Scalloped depressions may coalesce, leading to the formation of large areas of pitted terrain.
The polygonal pattern of fractures resembles permafrost polygons that form in terrestrial polar and high alpine regions by seasonal-to-annual contraction of the permafrost (permanently frozen ground). On Earth, such polygons indicate the presence of ground ice.
On Earth these polygons are most often seen in mud, usually suggesting a drying process where the ground contracts with the lose of fluid. On Mars the cracks probably also form from contraction, but not by the lose of fluid but the lose of water ice as it sublimates into a gas.
These polygons and scallops illustrate an important feature of Mars’ vast northern plains. On large scales these plains appear flat and featureless. Up close however many many strange features, like the polygons and scallops in this image, come into view.

New Horizons team renames “Ultima Thule” to “Arrokoth”
The New Horizons team has renamed the Kuiper Belt object that the spacecraft flew past on January 1, 2019 from its informal nickname of “Ultima Thule” to “Arrokoth,” which means “sky” in Powhatan/Algonquian language.
This official, and very politically correct, name has apparently gotten the stamp of approval from the IAU.
In accordance with IAU naming conventions, the discovery team earned the privilege of selecting a permanent name for the celestial body. The team used this convention to associate the culture of the native peoples who lived in the region where the object was discovered; in this case, both the Hubble Space Telescope (at the Space Telescope Science Institute) and the New Horizons mission (at the Johns Hopkins Applied Physics Laboratory) are operated out of Maryland — a tie to the significance of the Chesapeake Bay region to the Powhatan people.
“We graciously accept this gift from the Powhatan people,” said Lori Glaze, director of NASA’s Planetary Science Division. “Bestowing the name Arrokoth signifies the strength and endurance of the indigenous Algonquian people of the Chesapeake region. Their heritage continues to be a guiding light for all who search for meaning and understanding of the origins of the universe and the celestial connection of humanity.” [emphasis mine]
It is a good name, especially because its pronunciation is straight-forward, unlike the nickname.
The blather from Glaze above, however, is quite disingenuous. The Algonquian people have had literally nothing to do with the modern scientific quest for “meaning and understanding of the origins of the unverse.” They were a stone-age culture, with no written language. It was western civilization that has made their present lives far better. And it was the heritage of western civilization, not “the indigenous Algonquian people” that made the New Horizons’ journey possible. Without the demand for knowledge and truth, as demanded by western civilization, we would still not know that Arrokoth even existed.
Astronomers discover star fleeing Milky Way at 3.7 million mph
Astronomers have discovered a star that rocketing out of the Milky Way at 3.7 million miles per hour because five million years ago it made a close approach to Sagittarius A* (prounounced “A-star”), the super-massive black at the center of the galaxy.
“The velocity of the discovered star is so high that it will inevitably leave the Galaxy and never return”, said Douglas Boubert from the University of Oxford, a co-author on the study.
Astronomers have wondered about high velocity stars since their discovery only two decades ago. S5-HVS1 is unprecedented due to its high speed and close passage to the Earth, “only” 29 thousand light years away. With this information, astronomers could track its journey back into the centre of the Milky Way, where a 4 million solar mass black hole, known as Sagittarius A*, lurks.
Almost certainly there are many such stars. They are just hard to spot.
Putin slams Roscosmos for continuing corruption at Vostochny
At a meeting yesterday Russian President Vladimir Putin blasted Roscosmos for the corruption at the new spaceport at Vostochny, noting that despite the prosecution of numerous individuals the criminal behavior continues.
Russian President Putin said at a government meeting on Monday that dozens of criminal cases and jailings had failed to stem theft at the Vostochny spaceport construction site….
“It has been stated a hundred times: you must work transparently because large funds are allocated. This project is actually of the national scope! But, despite this, hundreds of millions, hundreds of millions [of rubles] are stolen! Several dozen criminal cases have been opened, the courts have already passed verdicts and some are serving their prison terms. However, things have not been put in order there the way it should have been done,” the Russian president said.
This article notes that out of $1.4 billion allocated for the spaceport, $169 million has been stolen. It does not however provide any details about any new corruption. Instead, it outlines the investigations and prosecutions that have already taken place.
According to Peskov, “at the first stage, 128 criminal cases were opened, which were later consolidated into 32 criminal cases and at the next stage the Investigative Committee singled out 21 cases and transferred them to the court of law and 18 persons were sentenced at the time,” Peskov said. “The Interior Ministry investigated 8 more cases,” he added.
Either Roscosmos officials revealed to Putin newly discovered corruption that the state-run press has been forbidden to discuss, or Putin’s criticism was aimed to discouraging future corruption.
Either way, Vostochny remains a typical government boondoggle. It has cost Russia far more than it should, and construction has been slow, beginning officially in 2012, though Russia has been working on it in fits and starts since the mid-2000s.
Hayabusa-2 to begin return voyage on November 13
In a press conference today the science team for the asteroid probe Hayabusa-2 announced that the spacecraft will begin the first stage of its journey back to Earth tomorrow, using its ion engine to slowly pull away from Ryugu.
That first stage will take a little less than a week. Once the spacecraft gets about 25 miles from Ryugu it will leave its sphere of gravitational influence, when it will then begin its cruise phase back to Earth.
Martha Raye – No Time At All
An evening pause: From the Broadway musical Pippin.
The words from this song mean more and more to me, with each passing year.
Here is a secret I never have told.
Maybe you’ll understand why.
I believe if I refuse to grow old
I can stay young till I die.
Now, I’ve known the fears of sixty-six years.
I’ve had troubles and tears by the score.
But the only thing I’d trade them for
Is sixty-seven more…
Chorus:
Oh, it’s time to start livin’.
Time to take a little from this world we’re given.
Time to take time, cause spring will turn to fall
In just no time at all.
And believe it or not, I see this also as a fitting song for Veterans Day.
Mars’ seasonally vanishing carbon dioxide polar cap
Click for full image.
Since the onset of the Martian spring in the northern hemisphere back in March of this year, scientists have been busy using the high resolution camera on Mars Reconnaissance Orbiter (MRO) to monitor the expected sublimation and disappearance of the cap of dry ice that falls as snow to become a winter layer mantling both the more permanent icecap of water 7,000 feet deep as well as the giant dune sand seas that surround that northern icecap.
The image on the right was first posted here on Behind the Black on June 6, 2019 as part of a long article describing that northern polar icecap and its annual evolution. It shows a set of dunes that Candice Hansen of the Planetary Science Institute in Arizona, who requested the image, has dubbed “Buzzell.” When that picture was taken in March, the frozen dry ice layer of translucent carbon dioxide still coated the dunes. The image’s darkness is because the Sun has just begun to rise above the horizon at this very high latitude location (84 degrees). The circular feature is likely a buried ancient crater, with the streaks indicating the prevailing wind direction blowing both sand and frost about.
On August 9, 2019 I provided an update on this monitoring, when new images of this same location were downloaded from MRO in April and June. MRO has now taken a new image of Buzzell, on October 2, 2019. Below the fold are all these images so that you can see the sublimation and disappearance of that dry ice layer over time.

We are not going to die from climate change
Tony Heller today published this quite thorough review of the failed climate predictions by global warming scientists/activists, while also providing a great summary of the real state of our climate.
You can disagree or question him on one point or another, but the overall data once again illustrates the uncertainty that surrounds climate science. We really do not know what is going on, and any predictions that claim we do are hogwash.
Above all, take a look at the section on the benefits of increased CO2 in the atmosphere. This data is widespread and robust, and has been confirmed by agriculturists for decades. The planet is getting greener and as a result more fertile as there has been an increase in atmospheric CO2.
Meanwhile, the fear-mongers insist the world will end in just over eleven years, based not on any real data but on their emotional desire for catastrophe.
Youtube and Facebook censoring name of Ukraine leaker
It is now being reported that both Youtube and Facebook are removing any content that mentions the name of CIA analyst Eric Ciaramella, the so-called “whistleblower” is really a leaker of classified information from a telephone conversation between President Trump and the president of the Ukraine.
From the original story at The Federalist:
For the record, it is perfectly legal to say or write the whistleblower’s name, unless you are the intelligence community inspector general (ICIG).
The federal whistleblower statute only requires the ICIG keep a whistleblower’s identity confidential, unless the ICIG determines the name necessary to disclose. No other government official or private citizen is required to protect the anonymity of a whistleblower. No such statute exists. So why the censorship on the whistleblower’s name?
Because disclosing the whistleblower’s name will likely lead to research that makes public what many on the right already know — the whistleblower blew his whistle based on a partisan agenda.
Ciaramella’s name is no secret. Not only has RealClearInvestigations revealed it, he was mentioned in the Mueller Report, and was even identified in published testimony from the secret hearings of Congressman Adam Schiff’s intelligence committee on impeachment.
For so-called news organizations to team-up to help fulfill the Democratic Party’s impeachment strategy is beyond disgraceful. This is one reason I do not allow Google advertising on Behind the Black. Google, which owns youtube, is a very corrupt company that is also a hand-in-glove supporter of the Democratic Party. This is why I also do not use it for my searches, going instead to either Startpage or DuckDuckGo. It is also why I encourage my readers to send me Evening Pause suggestions from video sources other than youtube.
Facebook is equally corrupt, and acts to block conservative sites from getting traffic. Now it is acting as an agent of the Democratic Party in its effort to overthrow the 2016 election.
One more point: It is also disgraceful for all news services, from the left and the right, to label Ciaramella a “whistleblower.” He is no such thing. All he did was leak the contents of Trump’s phonecall, based not on direct knowledge but on hearsay, and then express his objections to Trump’s foreign policy based on what he falsely thought had happened during that call. The transcript of that call demonstrates this unequivocally.
Moreover, Trump is the president. He sets foreign policy, not some lowlife CIA bureaucrat. Ciaramella broke his CIA security clearance by leaking and then spreading this tale. He should be fired, not anointed the honorary title of “whistleblower.”
SpaceX successfully launches 60 Starlink satellites
Capitalism in space: SpaceX today successfully launched 60 more satellites in its Starlink internet satellites, while also reusing for the first time a Falcon first stage for a fourth time, reusing a fairing for the first time. The first stage successfully completed a barge landing. No word on whether they were able to recover the fairings.
I have embedded the replay of the live stream below the fold. They now have proved the capability of recovering and reusing 70% of their rocket.
The leaders in the 2019 launch race:
22 China
17 Russia
11 SpaceX
6 Europe (Arianespace)
The U.S. now leads China 23 to 22 in the national rankings.
