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.

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.
While the first House proposal for NASA’s 2021 budget has rejected the Trump administration’s request for a total $3 billion increase for the agency to fund Artemis so that it can complete a manned mission to the Moon by 2024, it also provided about 18% of the funds requested for building the manned lunar lander required for that mission.
Back in February, the White House asked for $3.37 billion in fiscal year 2021 to accelerate development of the lander.
Democrats in the House have been skeptical of the 2024 launch date—some see it as political due to the timing of the next presidential election—and so have been slow to fund the lander. In its budget, the House appropriates $1.56 billion for “Exploration Research and Development.” This includes funding for the lander, Lunar Gateway, and other activities related to the Moon’s surface, of which more than $600 million can be used for the lander.
The House also provided a boost of $343 million to SLS.
My guess is that the Democrats in the House are working to keep Artemis going because of the jobs it brings to their districts, but want to slow it down enough so that it cannot succeed while Trump is in office. Thus, the release of some funds for the lunar lander, but not enough to build it, now.
The House proposal also includes a loosening on Congress’s mandate that Europa Clipper must launch on SLS. NASA is now given the option to consider other alternatives if SLS is not avaiable, which means that NASA can now consider using the Falcon Heavy instead.
This proposal must still pass the Republican-controlled Senate, so expect more changes.
The engineering team for InSight’s German-built digging tool, dubbed the mole, yesterday reported that it is once again no longer driving into the ground.
Previously they had been able to make progress by having InSight’s scoop press down on the mole. Once the top of the mole however was below ground, the scoop could no longer provide that support, and at that point the mole began bouncing again with each hammer-stroke, the surrounding Martian dirt unable to provide the friction to hold the mole down.
As shown by the illustration above, they are now going to try using the scoop to fill the hole and then use the scoop to press down on the dirt, with the hope this will provide the structural friction required to hold the mole in place after each hammer stroke. This effort will take time, and will prevent the scoop from doing its other work. They are therefore taking a pause until August before beginning the hole-filling operation.
The tenth anniversary retrospective of Behind the Black continues: I first posted these rules pertaining to commenting on Behind the Black on December 31, 2017, but have always adhered to them.
Anyone, without registering, can come this website and comment about anything (though preferably in connection to something I have posted), as long as they act like an adult. If they want to point out an error in something I’ve written, great. If they want to disagree with me civilly, even better. All they have to do is keep their language clean and not resort to childish insults.
Over the years since I have been amazed how many people in today’s increasingly barbaric culture can’t seem to do this simple thing. Thus I think these rules bear repeating, if only to outline to my many new readers where I stand on this issue. (Note that since I posted this I have relaxed the rules slightly. First time offenders are now issued a warning instead of being suspended immediately.)
———————
No obscenities on Behind the Black
I have stated this now bluntly more than a few times. I will not tolerate obscenities or curse words on this website. Despite this, today two different regular commenters thought it was perfectly fine to ignore these rules. One I have suspended for a week. The other might be.
The rest of the world might want to wallow in barbarism and ill behavior, but it will not happen here. This is my workplace. If you want to participate in the conversation on Behind the Black, I expect you to act like a civilized adult. If you can’t abide by these rules, then go somewhere else.
And don’t think it is okay to quote someone else verbatim and get away with this. As I noted just now in a reply to the suspended commenter, when Richard Nixon’s White House used the term [expletive deleted] everyone knew what it meant. It wasn’t a great solution, but it at least showed that they recognized that it was inappropriate to nonchalantly print obscenities, even ones spoken by the president. At the same time, they knew they couldn’t edit the transcripts, so they found a way to make it clear what was on the tapes without adding to the misbehavior.
Consider this a final warning. From now on I will not simply delete the obscenity and issue a warning. From now on, any violation of this rule will get an immediate suspension for a week. A second violation by the same person will get them banned.
