An evening pause: Hat tip Tom Biggar.
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.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"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
New data confirms and localizes uplifted lunar dust as seen by Apollo astronauts
The uncertainty of science: In a paper released today, scientists reveal the detection of electrostatic dust events on the Moon similar to those observed by Apollo astronauts, and find that these events might not be global but instead confined to craters during twilight. From the abstract:
Lunar horizon glows observed by the Apollo missions suggested a dense dust exosphere near the lunar terminator. But later missions failed to see such a high‐density dust exosphere. Why the Apollo missions could observe so large number of dust grains remains a mystery. For the first time, we report five dust enhancement events observed by the Lunar Dust Experiment on board Lunar Atmosphere and Dust Environment Explorer [LADEE] mission, which happen near a twilight crater with dust densities comparable to the Apollo measurements. Moreover, the dust densities are larger on the downstream side of the crater and favor a higher solar wind temperature, consistent with an electrostatic dust lofting from the negatively charged crater floor. We also check the Apollo observations and find similar twilight craters, suggesting that the so‐called dust exosphere is not a global phenomenon but just a local electrified dust fountain near twilight craters.
The dust clouds the astronauts thought they saw near the horizon have been theorized to be dust uplifted by static electricity. However, all later missions had so far failed to detect this phenomenon, until now. That the result also pinpoints the location and ties it to twilight is important for future missions to the Moon. Astronauts can thus minimize any damage by this dust by shutting down operations during lunar twilight periods.
Breaking: Starship prototype #9 tips over inside assembly building
It appears from the 24-hour live stream provided by LabPadre that the ninth Starship prototype tipped over inside the assembly building to rest against one wall. You can see it happen at about 8 seconds into the video below:
No word on whether anyone was hurt, nor any information about the cause. My guess is that it occurred during the operations to move this prototype to the launchpad.
UPDATE: It appears no one was hurt, but there is damage to the fins, which might also mean damage to the hull. This in turn might make it unsafe to fly this prototype, as the hull forms the walls of the methane/oxygen tanks.
The day has not been good for SpaceX. Earlier they had to scrub the launch of a commercial communications satellite at T-30 seconds for reasons that they did not provide. High altitude winds had delayed the launch an hour or so, but it appears this was not the reason. According to SpaceX’s website, “SpaceX is standing down from Friday’s launch attempt of the SXM-7 mission to perform additional ground system checkouts.” They are targeting Sunday for the next launch attempt.
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.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“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.

Strange crater in the basement of Mars
Click for full image.
Today’s cool image to the right, cropped and reduced to post here, is intriguing for a number of reasons. Taken on September 11, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), it shows a partially buried crater found in the middle of Hellas Basin, the lowest point on Mars and what I like to call the red planet’s basement.
What makes this crater intriguing is the layered pile of material filling its interior. If I didn’t know any better, I would think some construction crew has used a bulldozer to push debris from the crater’s right half in order to smooth the ground in preparation for building a strip mall, office building, or housing development.
This of course is not what happened. Then what did create those layered piles in the crater’s left half?

Boeing and NASA delay again the 2nd unmanned demo flight of Starliner
Boeing and NASA yesterday announced that they now plan to fly the second unmanned demo flight of Starliner in late March, rather in January as last scheduled.
Though there have been hints for awhile that a launch close to the start of the new year was no longer likely, this announcement confirms those hints. This means that it will have taken Boeing more than a year to fix the software issues that forced the first demo mission to abort its docking with ISS and come back early.
Whether this will delay the manned mission, which they are still targeting for as early as the summer of ’21, remains unclear. I think it will all depend on how well that the demo mission goes.

ULA’s Delta-4 Heavy successfully launches reconnaissance satellite
Capitalism in space: After a several month delay, ULA’s Delta-4 Heavy tonight successfully launched a reconnaissance satellite for the National Reconnaissance Office.
The leaders in the 2020 launch race:
33 China
23 SpaceX
13 Russia
6 ULA
5 Rocket Lab
5 Europe (Arianespace)
The U.S. now leads China 37 to 33 in the national rankings. The U.S. launch total this year matches the number of launches achieved in 1969, and is the most launches by the U.S. in a single year since then.

Arizona state senate to hold official hearing tomorrow on election
In a major shift, the Arizona state senate will tomorrow to hold an official hearing, with subpoena powers, on the questions relating to the vote count of the November 3rd election.
The hearing will be live streamed on the Arizona government’s website.
Whether it will be substantive, or designed to obscure the issues, remains unclear. The track record of the Republican leadership nationwide for the past two decades has consistently had them mouth platitudes in order to con their conservative base into thinking they were working in their interest, when in truth that leadership was repeatedly trying to do the exact opposite.
I hope I am wrong. It does appear that the many serious and substantive allegations relating to the vote are forcing the Republican leadership to respond, even if it is against their desire. Such an official Senate hearing would have to be called by the Senate president, Republican Karen Fann, which means it must have her endorsement.
Morocco agrees to Abraham accords, normalizing relations with Israel
Today President Trump announced that Morocco has agreed to become the fourth Islamic/Arab nation to sign the Abraham Accords, thus establishing normal diplomatic relations with Israel.
America gave Morocco an important concession as part of the deal. “Today, I signed a proclamation recognizing Moroccan sovereignty over the Western Sahara,” Trump added. “Morocco’s serious, credible, and realistic autonomy proposal is the ONLY basis for a just and lasting solution for enduring peace and prosperity! Morocco recognized the United States in 1777. It is thus fitting we recognize their sovereignty over the Western Sahara.”
Whether these deals will survive a Biden administration remains unclear. What is clear is that unlike any administration since the Carter administration in the late 1970s, Trump has successfully achieved the first peace deals between Israel and its Arab neighbors. His approach, different than the accepted wisdoms of the Washington establishment, succeeded where those accepted wisdoms had failed.
It is a shame that the unmitigated and irrational hate that so many on the left have of Trump has made them incapable of recognizing this accomplishment. The nation, in fact the world, should be celebrating these deals with enthusiastic joy. It is not, for these childish reasons.
Video: How election officials can cheat with Dominion voting software
The video is from today’s hearing in the Georgia legislature on the questions regarding the November 3rd election. Just watch. As noted at the link where I got the video:
Elections Supervisor Misty Martin gives a hands on demonstration of how to cheat with Dominion. This video was shown today by Colonel Waldren during his Georgia House of Representatives testimony.
The Dominion voting machines that Georgia and several other states use are open to manipulation during the counting process. This first of two videos shows the weaknesses of the system and the ways in which an unscrupulous election official may alter ballots with virtually no chance of being caught.
The point here is not whether anyone tampered with the results. The point is that the Dominion software used is utterly unreliable and can be used easily to tamper with the results. Any election that depended on this software is thus highly suspect, and should be thrown out.
It also means that if this software is used we cannot trust the results from the runoff of two Senate races in Georgia in January.
Starship: Old-fashioned American know-how
Yesterday’s truly epic first flight of SpaceX’s giant Starship rocket illustrated several truths that bear repeating, in clear and forceful language.
SpaceX succeeded because its company philosophy is open-minded, fearless, and thus free.
The open-mindedness culture comes from Elon Musk’s insistence that they never settle on any design if they can find a better way to do it. It is this approach that drives the company’s developmental process. The first Falcon 1 rocket made orbit, but despite that triumph Musk quickly abandoned it for the Falcon 9 when it was clear that it wasn’t powerful enough to garner enough satellite business.
The Falcon 9 that first launched in 2008 was a very different rocket from the Falcon 9 that launches today, as shown by the two pictures below. In the 2008 Falcon 9 the engines were configured differently and it had no legs. The modern Falcon 9 has landing legs, a different engine arrangement, and much of the innards have been redesigned to give the rocket more oomph.
