An evening pause: Worth watching more than once, if only to escape the insanity of our time.
I can’t help wondering however why they all are walking on this route, and what is it they stop to look at to the right at one point? And why is one crawling on its belly?

OSIRIS-REx has apparently successfully touched the surface of Bennu, grabbed a sample, and backed away without damage.
The link takes you to my embed of NASA’s live stream, which is mostly pr garbage. However, it is providing live updates from the mission control team, as it happens. Most of time, the NASA people running their pr effort even have the sense to shut up when such updates come it.
Right now we do not know how much of a sample was obtained. It will take some analysis of data and images to find out. They will know by the time of tomorrow’s press conference at 5 pm (Eastern).

The photo to the right, released today by the science team of Lunar Reconnaissance Orbiter (LRO), takes a overhead view of the unusual crater dubbed Ryder (named after lunar scientist Graham Ryder).
The crater is located on the Moon’s far side, on the edge of the South Pole-Aitken Basin, the Moon’s largest and possibly oldest impact basin. What makes Ryder Crater intriguing is its strange shape, as well as its interior north-south interior ridge.
This crater was featured previously in 2012 in a spectacular oblique image looking east across the crater. Then, the scientists theorized its strange shape was caused by two factors, first that the impact was oblique, and second that it occurred on a steep slope.
Today’s release adds another factor that might explain the interior ridge. The context map below makes that explanation obvious.

OSIRIS-REx superimposed. Click for full image.
Spaceflight Now today published a nicely detailed article summarizing the entire OSIRIS-REx mission to the asteroid Bennu, in anticipation of today’s attempt to grab a sample from that asteroid’s surface.
If you want to understand what is happening today, this article does a nice job of outlining everything.
I have embedded the live stream of the sample grab below the fold. It begins at 5 pm (Eastern) today. Be warned that it will show very little of the actual event, as the spacecraft will not be sending much data back to Earth today, during these operations. All we will really find out is if the grab happened, or was aborted to avoid risks, or occurred but the spacecraft was impacted by flying material during the grab. (Let us hope that this last option does not occur.)
The first images and data will not arrive until tomorrow, to be released during a press conference scheduled for 5 pm (Eastern).

Citizen scientist Gerald Eichstädt has created a two-image blink animation from Juno images of Jupiter that shows the changes in the two oppositely rotating storm vortices, shown on the right. As he notes.
Two vortices or eddies, one cyclonic, the other one anticyclonic, can propell themselves mutually and slowly within the overall context they are embedded in.
…The rotation of the two vortices is perceptible in the image sequence taken within nine minutes. The cyclonic eddy is located at the left, the anticyclonic one at the right. The motion of the vortex pair, however, is too slow to be resolved. But the morphology of the cloud tops points towards a relative upward motion in this rendition.
That the two storms also invoke face I am sure also had something to do with his decision to showcase this data. Unlike the face on Mars, this face is real, though relatively temporary. It will eventually break apart as Jupiter’s storms evolve.
The animation can be seen at the link.
The new colonial movement: China this week outlined some of its space ambitions for the 2020s, updating its planned lunar unmanned program as well as developments in its rocket industry.
For the Moon they plan the following:
Chang’e 6, a backup mission for this year’s sample-return launch, is scheduled to head to the moon in 2023 or 2024; Chang’e 7 is planned to launch around 2024 with the dual aims of landing on the south pole of the moon and closely studying the region from orbit. An eighth mission is also in the works for later this decade.
As for their rocket industry, CASIC, the government entity that supervises China’s commercial space activities (including a number of private companies operating independently but supervised closely by it) announced plans for a reusable two-stage reusable spaceplane, a new constellation of satellites, and a number of new quick-launch solid rockets aimed at doubling their launch rate.
Even though Russian astronauts have now patched with Kapton tape the 1-inch crack where they thought the leak in the Zvezda module on ISS was located, the loss of air has continued, and even increased.
The pressure in the Zvezda module of the International Space Station (ISS) keeps lowering, although the fissure was patched with Kapton tape, and even faster than before the fix, the crew told the ground control on Tuesday, as broadcast by NASA.
They are going to add more tape to the patch and see if this seals the leak.
Meanwhile, there has been little discussion about the nature of this 1-inch crack. Was it caused by a micrometeorite, or is it a stress fracture? And where exactly is it, and does that location help explain it?
Inquiring minds need to know!
Capitalism in space: SpaceX last night successfully completed the static fire test on its eighth Starship prototype, for the first time firing three Raptor engines simultanously.
Video of the test, cued to just before ignition, is embedded below the fold.
The company will now install the nosecone on the prototype, repeat this static fire test again in about a week, and then prepare it for its first flight, an expected 50,000 foot hop. I expect that hop to occur in early to mid-November, about the same time the next manned Dragon flight will occur.

For today’s cool image, we are going to start from afar and zoom in, because I think that might be the best way to gain at least a rudimentary understanding of the strange geology visible at this one particular Martian location.
The first image, to the right, is the overview map. The red cross indicates our target, a chaotic canyon that flows into the larger Kasai Valles, one of Mars’ largest and longest canyons and possibly only exceeded in size by Valles Marineris. This part of Kasai is near its end, where it drains out into the vast northern lowland plains of Mars.
The second image, below, comes from the wide angle camera on Mars Reconnaissance Orbiter (MRO).

In June, shortly after George Floyd met his tragic death while in the hands of arresting police officers, former vice president and Democratic Party presidential candidate Joe Biden was asked by a television reporter, “Do you believe there is systemic racism in law enforcement?” Biden responded as follows:
“Absolutely,” Biden responded. “But it’s not just in law enforcement, it’s across the board. It’s in housing, it’s in education, and it’s in everything we do. It’s real. It’s genuine. It’s serious.”
The absurdity of Biden’s response is immeasurable. What he says here is a lie, a lie so absurd it is both astonishing and horrifying that anyone believes it. There has been no systematic racism in America for generations, and anyone who thinks so is either lying to themselves, or trying to spread lies to others.
The biggest irony is that those who apparently believe this lie the most, our younger college-aged generation, have grown up in a society where for decades blacks with talent and determination have had no problem achieving success in all sorts of business and fields, with some even becoming the dominate figure in their field. (Think of Barack Obama and Oprah Winfrey as only two examples.) They can also marry anyone they want, can go anywhere they want, and achieve anything they want. Nothing stops them but their own limitations.

Russian astronauts on ISS have successfully repaired the oxygen regeneration unit on the Zvezda module.
From the TASS article was this additional information:
The Elektron-VM oxygen supply system developed by Russia’s Research and Design Institute of Chemical Machine-Building (NIIChimMash) has been operational aboard the space station since its creation. The system can generate from 25 to 160 liters of oxygen per hour and additionally from 50 to 320 liters of hydrogen per hour. In April 2010, it took the ISS crew several days to fix the broken system.
No word yet on any new information on the “fracture” that is causing the slow leak.
Capitalism in space: SpaceX today successfully launched another 60 Starlink satellites, raising the constellation to more than 800 satellites.
The first stage successfully landed, for the sixth time, on a drone ship. The company also recovered both fairings, which were making their third flight. With one fairing’s recovery however the net broke on the ship, which might have damaged it this time.
The leaders in the 2020 launch race:
26 China
17 SpaceX
11 Russia
4 ULA
4 Europe (Arianespace)
The U.S. had regained the lead over China, 27 to 26, in the national rankings.
Capitalism in space: Another high altitude balloon company, this time from Spain, is now vying for the space tourism market.
EOS-X Space, a Spanish startup, wants to take 10,000 people to the frontier of space within the next 10 years. With EOS-X Space, the journeys won’t be in rockets or ultrasonic planes. They’ll instead take place in a pressurized capsule propelled by a balloon that will rise to an altitude of up to 40 kilometers, or nearly 25 miles.
This means space tourists won’t have to wear a suit for the duration of the trip, nor will they have to do any physical preparation. Depending on the weather, each trip is set to last four or five hours.
They are targeting the same market as the American company Space Perspectives, which hopes to begin flying tourists on its stratospheric balloon, dubbed Neptune, by ’24.
The board of Spaceport America, Virgin Galactic’s launchsite for its SpaceShipTwo suborbital manned spacecraft, yesterday fired its long time Executive Directory Dan Hicks, at the same time governor of New Mexico removed one board member.
Hicks, the spaceport’s CEO since 2016, has been on administrative leave since June while allegations of mismanagement and abuse of authority have been under investigation by the New Mexico State Auditor and the New Mexico Spaceport Authority, the public body governing the spaceport.
The McHard Accounting Consulting firm, a forensic accounting firm based in Albuquerque, conducted an investigation which was then referred to the state auditor. Keyes informed a state legislative committee this summer the allegations included potential criminal activity.
Spaceport American had been made gigantic promises by Richard Branson back in the mid-2000s, including hundreds of tourist flights per year on SpaceShipTwo, all of which would bring lots of cash to the spaceport and to New Mexico. All came to naught. I suspect those failed promises are somehow connected to the accusations here.
ULA has now delayed indefinitely the launch of a military reconnaissance satellite using its Delta 4 Heavy rocket because of ongoing issues in the swing arms on the launch tower.
According to ULA’s CEO, Tory Bruno:
..ULA was “working through an issue with pad hydraulics” associated with the swing arm retraction system at the Delta 4 launch pad. Three swing arms feeding propellants and conditioned air to the rocket and its satellite payload are designed to retract as the Delta 4-Heavy lifts off.
“Fixing is always easy,” Bruno tweeted. “Making sure something stays fixed takes more work and lots of discipline.”
This launch has been delayed numerous times in the past two months, almost always because of a variety of different problems, most related to the launchpad, with two scrubs occurring as launch aborts at launch. As the article at the link correctly notes,
The repeated problems with different parts of the Delta 4-Heavy’s launch pad have raised questions about aging infrastructure at pad 37B, which was originally built to support Saturn rocket launches in the 1960s, then mothballed until Boeing took over the facility in the 1990s for the Delta 4 program.
Boeing built the towering mobile gantry for the Delta 4 rocket, along with a then-new fixed umbilical tower with huge swing arms designed to pull away from the launcher as it climbs away from the pad.
The age of the launchpad, combined with the expensive complexity of the Delta 4 Heavy that results in very few launches spread over many years, cannot result in reliable operations.
An evening pause: Hat tip Jim Mallamace, who accurately describes this as “a mildly amusing short sci-fi film.”
My thought in watching this short film is that I have been watching and reading sci-fi movies and books about a oppressive future imposed by technology for almost sixty years. All were written as warnings of a future to avoid. Instead, it appears we have taken them all as instruction manuals.
The corruption of modern science and our intellectual class was well illustrated today by the following headline and article in the peer review journal Science:
Act now, wait for perfect evidence later, says ‘high priestess’ of U.K. COVID-19 masking campaign
From the article’s lead:
In May, when several prominent U.K. scientists pushed back against a Royal Society report recommending face masks to help control the spread of COVID-19, Trisha Greenhalgh was furious. The scientists argued there was insufficient support in the scientific literature for the efficacy of masks, and the U.K. government, following their lead, declined to mandate masks for the general public.
“The search for perfect evidence may be the enemy of good policy,” Greenhalgh, a physician and expert in health care delivery at the University of Oxford, fumed in the Boston Review. “As with parachutes for jumping out of airplanes, it is time to act without waiting for randomized controlled trial evidence.” [emphasis mine]
The highlighted words have been the typical argument of the global warming crowd for decades. “We can’t wait for evidence! We need to act now before it’s too late!”
Moreover, she — along with the writer of this Science article — also copies another global warming dishonest tactic, posing a false argument by claiming that the opposing scientists requried a “randomized controlled trial” to demonstrate the usefulness of masks. This is an absurd misstatement, as it ignores decades of research that already exists and was referenced by those opposing scientists, that showed that mandating widespread mask use was generally a bad idea, and would accomplish nothing good.

The new colonial movement: China’s Chang’e-4 lander and Yutu-2 rover have both been reactivated for their 23rd lunar day on far side of the Moon.
Yutu 2 is set to continue its journey northwest from the landing site and will target a roughly 12-inch (30 centimeters) rock on the rim of a nearby crater for analysis with a spectrometer. The rover has used that instrument to analyze a range of specimens in Von Kármán crater, notably causing a stir when it discovered an impact melt breccia initially described as “gel-like.”
It is the hope of the Chinese scientists that this rock will be ejected material from that crater and will have come from the lunar interior.
Also, though you need to read Chinese to understand how to access it, the project has released to the public another batch of data from both spacecraft.
