Capitalism in space: SpaceX’s sixth Starship prototype yesterday successfully completed its first static fire engine test.
Below is a six-second video of that test. Assuming this test went well, it appears they are aiming to do a 150 meter hop this coming weekend (around August 29-30), adding even more excitement to this week’s busy rocket schedule.
The Russian government today revealed that it has agreed to spend $470 million to restore the Sea Launch floating launchpad.
Before Russia took possession the platform had been stripped of much of its equipment, probably as part of the final financial settlement with Boeing, which had once been a part owner (with Russia and the Ukraine). As part of the break-up of the company Russia had had to buy Boeing off (after many lawsuits) to gain full ownership.
As noted by Deputy Prime Minister Yuri Borisov, “It is a unique structure unparalleled in the world. Some have plans for building something similar. It would be very silly of us, if we decided against restoring the Sea Launch and using its services. Technically all this is possible.”
For Russia the platform gives them the potential of a launch site at the equator, something they have never had.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
UPDATE: Rocket Lab’s launch has been delayed to 11:05 pm (Eastern) August 28 due of weather.
Beginning tomorrow, the next four days will be very busy for the American space rocket industry, with three companies attempting to complete four different launches.
First comes Rocket Lab, which will attempt its first launch of its Electron rocket since its first operational launch failure on July 4. Launch is scheduled for 11:05 pm (Eastern) on August 26th.
Next ULA is scheduled to use its most powerful rocket, the Delta 4 Heavy, to put a National Reconnaissance Office surveillance satellite into orbit. Launch is set for 2:12 am (Eastern) on August 27th. This very expensive rocket (which costs three to four times that of a Falcon Heavy) has only four launches left before being permanently retired.
Then SpaceX will attempt two launches in quick succession. The first will launch at 7:19 pm (Eastern) on August 27th, putting up an Argentinian Earth observation radar satellite. On this launch the first stage is a new one, and will attempt the first landing at Cape Canaveral since March 2020.
SpaceX will then follow with its third Starlink launch this month and twelfth overall, scheduled for 10:30 am (Eastern) on August 29th out of its facility at Cape Canaveral, assuming the other launches at Kennedy go as planned.
Moreover, the startup smallsat rocket company Astra is also aiming to attempt its first test launch before the end of August. The date is not yet set.
Busy times for sure, but note that this is only the beginning. I expect by the end of the 2020s the launch schedule will get increasingly packed. Soon having three three launches per week will seem routine.
This is beginning to be a weekly event: Today another professor, this time from Texas A&M, was arrested for lying in grant applications by not disclosing his university affiliations in China.
Professor Zhengdong Cheng, 53, is charged with conspiracy, making false statements and wire fraud. Cheng led a team conducting research for NASA while secretly working with China, according to federal investigators.
“Dr. Cheng is accused of hiding his affiliation with the Guangdong University of Technology, along with other foreign universities, while disregarding the rules established under his NASA contract during his employment at TAMU,” said FBI Houston Special Agent in Charge Perrye K. Turner.
More and more it looks to me as if China cannot invent anything themselves, only update what they steal.
Now available in hardback and paperback as well as ebook!
From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

This essay is going to include a number of graphs [data source], showing the daily numbers related to the Wuhan virus since the beginning of the epidemic. All show that the epidemic is truly tapering off or ending, regardless of where you live. All also strongly suggest that the lock downs, restrictions, mask mandates, and the many other odious rules that were imposed initially for just a few weeks to prevent our healthcare system from being overwhelmed but have remained in force now for many months should immediately be cancelled or removed.
And yet, these restrictions remain, in one form or another, with some rules (such as the mandate to wear masks) being expanded, sometimes to the point of idiocy. That they remain proves again that those lock downs, restrictions, mask mandates and other rules had little to do with the disease. Instead their goal was to impose new authoritarian rules on the citizenry, meant to establish new precedents of power and control for the petty dictators who wish to rule us like servants.
The first graph to the right shows the daily deaths across the entire United States. As you can see, after reaching a peak in late April, the disease began fading with the coming of warmer weather, as these seasonal flu-like diseases always do. Then, beginning in early July we saw a slow new rise that peaked in early August and has since begun tapering off.
The second peak is puzzling for a seasonal disease, but we might be able to explain it by thinking about the consequences of the lock downs. Normally a seasonal disease hits, and than fades. Normally however there are no lock downs and restrictions, which means the virus has a chance to quickly spread throughout the population, reach herd immunity, and then die.
This time however we decided to slow the disease’s spread, which means that at some point, when those restrictions were eased (not removed) we were guaranteed to see a new uptick. This is what has happened, though the uptick as should be expected is relatively small, nowhere near as severe as the initial peak.
In fact, to understand the true impact of this virus it is essential to recognize several very important components of these death numbers. First, these numbers are likely exaggerated, by at least 25%. Hospitals get more money if they claim a death came from COVID-19, so they have a strong incentive to assign the cause of death to COVID-19, even when it was only a minor factor. There is ample evidence this has been happening.
These extra benefits have also meant that COVID-19 has cured the flu! This year will see the fewest flu deaths ever, now estimated to be only 6,605 total, an absurdly low number compared to every other year, ever. In other words, of the 168,000 or so deaths assigned to the Wuhan flu a large percentage, maybe as much as half, might actually be cases that would have died (or did die) from the flu.
All told, these numbers tell us that the total deaths this year are simply not much higher than in past years, that they have either been overstated or assigned incorrectly to COVID-19. A hard look instead suggests actually that this year’s epidemic was essentially nothing more than a somewhat worse flu season, painful, but hardly justifying the panic that we’ve seen.
Second, the disease’s mortality continues to be confined almost entirely with the aged sick, with 80% of all COVID-19 deaths occurring in people over 65. Like the flu, the Wuhan flu carries practically no threat for the young and the healthy. If anything, the sooner they can all get infected, the sooner the epidemic will end, actually producing the fewest deaths because the healthy population will choke it off before it can reach the vulnerable parts of the population.
Unfortunately, we did not let this happen, and the consequences for the older population is tragic, as shown by the next two graphs.

"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke
China yesterday used its Long March 2D rocket to successfully launch an Earth observation satellite plus two smallsats into orbit.
The leaders in the 2020 launch race:
20 China
13 SpaceX
9 Russia
4 ULA
The U.S. still leads China 21 to 20 in the national rankings.
Based on a detailed update today at NASASpaceFlight.com on the status of ULA’s new Vulcan rocket, it appears that while everything is proceeding as scheduled for a 2021 launch debut, the big issue that might cause a delay is Blue Origin’s BE-4 rocket engine, to be used in Vulcan’s first stage.
Speaking to the Denver Business Journal yesterday, ULA CEO Tory Bruno noted an ongoing issue with BE-4’s turbopumps but voiced his confidence that the issue would soon be resolved and that it would not impact Vulcan’s schedule at this time.
…Development of the BE-4 has long been seen as the critical path for Vulcan. ULA exercised an option within the U.S. Space Force’s National Security Space Launch (NSSL) Phase 2 award proposal and bid Atlas V as a backup vehicle for Vulcan in case the latter ran into development or certification issues.
When asked when ULA would have to inform the Space Force of its desire to switch one of the first awarded NSSL missions from Vulcan to Atlas V under a purely hypothetical BE-4 or Vulcan issue, Mr. Peller [VP of Major Development for ULA] did not comment directly, instead affirming ULA’s confidence that all of their NSSL missions would fly on Vulcan. [emphasis mine]
From the Denver Business Journal article:
Blue Origin is still troubleshooting the 75,000-horsepower pumps that bring fuel to the BE-4’s main combustion chamber, Bruno said, adding that he’s confident the issues will soon be solved. “There’s very little technical risk,” he said. “It isn’t easy, but we know we can do it.” [emphasis mine]
This is the first public admission I’ve seen anywhere of a specific problem with the BE-4 engine. It also suggests strongly that the problem has been long-standing, and has not yet been solved.
Both articles also make it clear that ULA is prepared to continue using both the Atlas 5 rocket and the Russian engines (that the BE-4 is supposed to replace) until 2027, if necessary.
While it could very well be that the BE-4’s turbopump issues are on the way to being solved and there will be no delays, the careful wording by Bruno and his head of development strongly suggests that they are aware of an issue and are trying to deflect press interest in it. In fact, the timing of this revelation, only six weeks after Blue Origin delivered to ULA its first BE-4 engine (a test version not flightworthy), suggests that ULA has only now become aware of the issue, and is now working to help solve it.
Stay tuned. I suspect all will become very clear within the next few months.

An evening pause: Performed live 1975.
Hat tip Diane Zimmerman.
It was all so unnecessary: A new analysis by scientists suggests strongly that COVID-19 was already widespread within the U.S. population before the national emergency was declared on March 13th and the lock downs thus imposed.
Although the limitations of our analysis limit the precision of our results, we can nonetheless conclude that unobserved SARS-CoV-2 infections in the United States by 12 March could have easily numbered in the hundreds of thousands … and quite possibly in excess of 1 million. This result, considered together with extensive presymptomatic and asymptomatic transmission of SARS-CoV-2, suggests that the United States was well past the possibility of containment by 12 March.
Essentially, what their analysis found is that COVID-19 had already arrived in the U.S. when our politicians panicked and destroyed our economy and millions of lives. By the time the lock downs were imposed the disease was here, and spreading fast. The lock downs were pointless, the social distancing was pointless, the house arrests were pointless, and most especially, the requirement to wear masks was pointless.
Like all flu-like viruses, COVID-19 was going to get here regardless. The best we could do is focus on protecting the most vulnerable (the aged sick), and go on with life boldly. Most of our politicians did not do that, and so they not only had more deaths among the aged sick than was necessary, they ruined everyone else’s lives as well.
And maybe the worst consequence of the Wuhan panic is that we now live in a culture that lives in fear of the flu, a disease that is merely a short sickness from which almost everyone recovers. Such a culture can only die, because it won’t have the courage to take any risks at all.

Using the Hubble Space Telescope, astronomers have obtained close-up images of Comet NEOWISE after it had survived its closest approach to the Sun. The photo to the right, cropped and reduced to post here, is one of Hubble’s two images.
Comets often break apart due to thermal and gravitational stresses at such close encounters, but Hubble’s view suggests that NEOWISE’s solid nucleus stayed intact. This heart of the comet is too small to be seen directly by Hubble. The ball of ice may be no more than 4.8 kilometres across. But the Hubble image does captures a portion of the vast cloud of gas and dust enveloping the nucleus, which measures about 18 000 kilometres across in this image.
Hubble’s observation also resolves a pair of jets from the nucleus shooting out in opposite directions. They emerge from the comet’s core as cones of dust and gas, and then are curved into broader fan-like structures by the rotation of the nucleus. Jets are the result of ice sublimating beneath the surface with the resulting dust/gas being squeezed out at high velocity.
Below the fold is a six-second movie made of Hubble’s two images, showing how the jets changed over a three hour time period on August 8th.
