In my last visit to Israel in 2018, my brother and sister-in-law took me sight-seeing to the northern parts of Israel near the Sea of Galilee. On our first night, we stayed at the home of one of their older friends, a man in his seventies.
That night we sat around their kitchen table so that they could catch up on family matters. At one point in the conversation our host reminisced about an older woman, now gone, who he had known in his childhood in the 1950s who had lived in Germany before and during World War II and had survived a concentration camp.
To paraphrase the story he told us, what this woman always remembered most starkly about that time, especially in the 1930s, was how difficult it was to get German friends who were not Jewish to believe the horrors she and other Jews were going through. To her, their calm nonchalant dismissal of the Nazi bigotry and oppression of Jews — too unbelievable to take seriously — was what had horrified her the most. Even twenty years later, it was this dismissal that appalled her the most, despite her time in a concentration camp and the death she had seen around her.
As he told us this story, what struck me was how similar my own experience has been. Time after time for the past four decades my liberal friends and relatives have refused to believe anything I say to them — always based on actual events — about politics and the growing corruption and bigotry within the Democratic Party. Like those decent Germans in the 1930s, these decent Americans find reasons to quickly dismiss what I say, without making any effort to find out if there is any merit to it.
In fact, less than two days after this very conversation it happened again. » Read more
Capitalism in space: During the processing to bring a used Falcon 9 first stage back to its hanger after its June 30th launch, one of the landing legs unexpectedly fell back to the ground during retraction.
I have embedded the video of the incident, cued to the event, below the fold. No one was hurt, and it appeared that nothing was damaged. It appears it happened because a cable holding the leg vertical snapped just before the leg got latched in place on the side of the rocket.

Engineers have now confirmed that Solar Orbiter, having completed its first close fly-by of the Sun, is working perfectly and is producing images and data better than expected.
They will release to the public the first images on July 16.
“The first images are exceeding our expectations,” says Daniel Müller, Solar Orbiter Project Scientist at ESA. “We can already see hints of very interesting phenomena that we have not been able to observe in detail before. The 10 instruments on board Solar Orbiter work beautifully, and together provide a holistic view of the Sun and the solar wind. This makes us confident that Solar Orbiter will help us answer profound open questions about the Sun.”
No other images of the Sun have been taken from such a close distance. During its first perihelion, the point in the spacecraft’s elliptical orbit closest to the Sun, Solar Orbiter got as close as 77 million kilometres from the star’s surface, about half the distance between the Sun and Earth. The spacecraft will eventually make much closer approaches to the Sun. The spacecraft is now in its cruise phase, gradually adjusting its orbit around the Sun. Once in its science phase, which will commence in late 2021, the spacecraft will get as close as 42 million kilometres from the Sun’s surface, closer than the planet Mercury. The spacecraft’s operators will gradually tilt Solar Orbiter’s orbit to enable the probe to get the first proper view of the Sun’s poles.
A previous spacecraft, Ulysses, flew over the Sun’s poles, but it did it from far away, and was designed not to take images but to study the Sun’s solar wind. Solar Orbiter is getting in close.
China today successfully used its Long March 3B rocket to launch a communications satellite.
The leaders in the 2020 launch race:
16 China
10 SpaceX
7 Russia
3 ULA
The scrub yesterday of a SpaceX Starlink launch as well as the launch failure by Rocket Lab this week has allowed China to catch up with the U.S. Both countries are now tied, 16-16, in the national rankings.
The tenth anniversary retrospective of Behind the Black continues: Despite my many essays on culture and politics, Behind the Black remains mostly a site reporting on space and science. Since the modern exploration of Mars is probably the most significant on-going event now in space, it seemed unsatisfactory to only repost one or two of my past articles on this subject, when I have probably have posted hundreds. Instead, this midnight repost will provide links to a bunch, divided into several topics.
Martian geology, shown in cool images
First, we have the many cool images I have posted on Mars, often tied to detailed descriptions of what scientists are now beginning to learn about the red planet’s mysterious geological history. The following are the most important, and will help readers better understand future cool images.
Future colonization
Next, two posts, both focused on the future exploration and colonization of Mars.

An evening pause: Some unusual juggling.

It is now full spring at the Martian south pole, and as should be expected much has been happening there. Like the Martian north pole, when sunlight arrives after the dark winter it hits the seasonally-placed mantle or cap of carbon dioxide snow and begins to melt it, in the alien ways things like this occur on Mars.
The two images to the right illustrate this process for one particular place located in what are called the south polar layered deposits. The two images, just released on July 1, 2020 from the high resolution camera on Mars Reconnaissance Orbiter (MRO) and taken on May 14 and May 30 respectively, had immediately caught my attention because they were labeled “Active Geyser Locale Dubbed Macclesfield.” Active geysers?! I immediately contacted Candy Hansen of the Planetary Science Institute in Tucson, Arizona, whom I correctly guessed had requested these photos. She explained,
The name for this site is of course informal, and it dates back to when I first started picking sites to monitor. I was so certain we would see active geysers here! We see their deposits, the fans on the surface, but so far we have not caught an actual eruption in progress.
The overview map of the south pole below provides some context.

The podcast for my two-hour appearance on the Space Show last night is now available here.
The Putin government yesterday arrested Ivan Safronov, a former journalist presently an advisor to that country’s space agency Roscosmos, for passing military secrets to the Czech government back in 2017 when he was employed by a daily newspaper.
It seems the press in Russia is highly skeptical of these charges.
Kommersant [the daily newspaper in which he had worked] put out a statement in support of Safronov, hailing him as one of the country’s top journalists and a “true patriot” who was deeply concerned about the state of the military and space industries that he covered. The newspaper described the accusations against him as “absurd.” The paper noted that rights activists, journalists, scientists and corporate officials who faced treason accusations found it difficult to defend themselves because of secrecy surrounding their cases and lack of public access. “As a result, the public has to rely on the narrative offered by special services, whose work has increasingly raised questions,” Kommersant said. “Journalists asking those questions find themselves under blow.”
About 20 journalists, including those who worked with Safronov for years, were detained outside FSB headquarters in Moscow when they picketed to protest his arrest. Some were handed court summons for violating a ban on street gatherings during the coronavirus pandemic, an offense punishable by an administrative fine.
Many former colleagues of Safronov alleged that the authorities may have wanted to take revenge for his reporting that exposed Russian military incidents and opaque arms trade deals.
It also appears that the charges have nothing to do with Safronov’s work at Roscosmos.
Capitalism in space: NASA yesterday released the results of its investigation into the issues that prevented Boeing’s manned Starliner capsule from successfully completing its unmanned demo flight to ISS in December, finding an additional 20 issues over the 61 initially identified shortly after the mission.
In closing out the seven-month investigation, NASA officials said Tuesday they have now identified 80 corrective actions, mostly involving software and testing, that must be done before the Starliner capsule launches again. The previous count was 61.
NASA officials also admitted that they had been so focused on making sure SpaceX’s Dragon capsule was going to work that they became lax in reviewing Boeing’s work. Now they not only are going to focus more on Boeing, they actually want to use SpaceX’s approach to software development throughout NASA.
NASA is also borrowing SpaceX’s “robust” approach to software, which involves going back to the designers following testing for feedback, said Kathy Lueders, NASA’s new human spaceflight chief who until a month ago managed commercial crew. She wants to see more of that type of approach across other NASA programs.
Though it seems absurd and incredible that NASA has not been consulting with its designers after testing, it is also not surprising. When it comes to designing and building anything at NASA the management processes there have routinely done a bad job for many years.
As for Starliner, it is expected it will take a few more months to fix these issues, which means the next unmanned test flight is likely still set for sometime in the fall, with the manned mission to follow next spring.
Chinese scientists have now published their analysis of the “gel-like” rocks seen by China’s Yutu-2 lunar rover back in October 2019, and have concluded that they are glasses produced from melt occurring during an impact.
The authors describe the material as a dark greenish and glistening impact melt breccia, measuring 20 inches by 6 inches (52 by 16 centimeters). These features are signs of possible presence of glasses, which are usually sourced from impact melts or from volcanic eruptions.
According to the paper, the breccia — broken fragment of minerals cemented together — was formed by impact-generated welding, cementing and agglutinating of lunar regolith and breccia. The material, they say, resembles lunar impact melt breccia samples returned by NASA’s Apollo missions. In particular, similarities with the Apollo samples designated 15466 and 70019 are noted, a comparison made earlier by lunar scientist Clive Neal at the University of Notre Dame. Sample 70019, collected by astronaut and trained geologist Harrison “Jack” Schmitt, is made of dark, broken fragments of minerals cemented together and black, shiny glass.
The results are not definitive, however. The paper notes that the analysis is limited by the fact that VNIS measurements were taken under bad illumination conditions and other factors.
This conclusion is not surprising, as the rover has been traveling through a region dominated by impact ejecta.
