A new hard aluminum alloy resistant to space radiation?

According to this press release, engineers have developed a new hard aluminum alloy that is also resistant to the high radiation seen in space, which in turn could make this lighter-than-steel metal practical for spacecraft.

Making spacecraft from aluminium is one solution, as aluminium is a light yet strong material. Alloys help aluminium become harder via precipitation strengthening, but the radiation encountered in space can dissolve the hardening precipitates with potentially disastrous and fatal consequences for astronauts.

But the research carried out at MIAMI-2 in partnership with Montanuniversitaet Leoben (MUL) in Austria has discovered that a particular hardening precipitate of a new aluminium alloy – developed by a group of metallurgists led by Professor Stefan Pogatscher (MUL) – does not dissolve when bombarded with particle radiation when compared with existing data on irradiation of conventional aluminium alloys.

If I understand this, traditional aluminum alloys have not been useful for building spacecraft because they cannot withstand the radiation of space. This alloy appears to solve this problem.

I would be interested in hearing what the space engineers in my readership think.

Newsom’s new lockdown in California triggered by totally normal numbers

The new lockdown edicts by California’s governor and petty dictator, Gavin Newsom, were triggered by numbers that are routine and have been for decades.

When California Governor Gavin Newsom set his 85% ICU capacity “trigger” to automatically start a new round of totalitarian lockdowns, he had zero doubt the number would be reached in December. How? Because that number is reached EVERY December. Knowing this, why wouldn’t he prepare by assisting hospitals across his state to increase ICU capacity?

…In any given year, most parts of California reach 90% ICU capacity in December. This is usually due to the surge in flu cases, but the flu is allegedly non-existent this year, replaced on paper by the more lucrative COVID-19 diagnoses preferred by hospitals. They knew it was coming, which is why they made moves separate from the state to increase ICU capacity.

In other words, the total number of cases in California’s hospitals is actually at this moment below, or at least completely normal. The only difference is that there are no flu cases. Instead, hospitals are claiming they are all COVID-19.

The lockdowns are there for only one purpose: To strike fear into the hearts of ordinary people, and to expand the power of the government, in complete violation of the entire Bill of Rights.

Welcome to fascist America.

Genesis cover

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

Weather delays Starship hop to December 8th; Musk arrives in Boca Chica

Starship on launch pad
Click for LabPadre live stream from which this still was captured.

Capitalism in space: Weather issues have delayed the first big hop of the eighth Starship prototype so that it is now scheduled for no earlier than tomorrow, December 8th.

That Elon Musk arrived in Boca Chica late on December 5th strongly suggests however the hop will finally happen this week, after several weeks of delays.

With Musk himself now on the ground in Texas to (presumably) oversee Starship SN8’s debut, the odds of launch later this week are arguably much better. Having now spent more than 10 weeks at the launch pad, at least twice as long as any Starship preceding it, there’s no small chance that SN8 – the first prototype of its kind – is starting to be more of a nuisance than an asset. By all appearances, Starship SN9 – essentially a “refined” copy of SN8 – is practically ready for launch with SN10 perhaps just a week or two behind it.

It also appears they have lowered the top planned altitude of the hop from 50,000 feet to about 40,000 feet.

Musk had tweeted earlier that SpaceX planned to live stream the event, which would be spectacular as they almost certainly have cameras on the spacecraft. If they don’t the LabPadre live stream above will also be an option.

Redwire successfully 3D prints ceramic parts in space

Capitalism in space: Redwire announced today that it has successfully for the first time 3D printed several ceramic parts in space on ISS.

The commercially developed in-space manufacturing facility successfully operated with full autonomy using additive stereolithography (SLA) technology and pre-ceramic resins to manufacture a single-piece ceramic turbine blisk on orbit along with a series of material test coupons. The successful manufacture of these test samples in space is an important milestone to demonstrate the proof-of-potential for CMM to produce ceramic parts that exceed the quality of turbine components made on Earth. The ceramic blisk and test coupons will be stowed and returned to Earth for analysis, aboard the SpaceX Dragon CRS-21 spacecraft. CMM, developed by Redwire subsidiary Made In Space, is the first SLA printer to operate on orbit.

The replicators of Star Trek are coming. The real ones won’t be like the ones in the television show, nor will they be used to produce food, but they are coming nonetheless. It is quite likely that the colonization of space will demand a revolution in 3D printing that will make it possible for almost all heavy industry manufacturing.

Conscious Choice cover

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.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Audit of Dominion machine found it routinely shifted votes to Biden

UPDATE: More information here. This does appear legitimate, and now demands that every Dominion tabulator nationwide be tested with a microscope.

Original article:
—————————
According to this Twitter thread today, officials in Ware County, Georgia, fed an equal number of votes for Trump and Biden into a Dominion tabulator, which then produced a 26% lead for Biden.

37 Trump votes used in the equal sample run had been “Switched” from Trump to Biden. In actual algorithmic terms this means that a vote for Trump was counted as 87% of a vote and a vote for Biden was counted as 113% of a vote.

Those conducting the test were so shocked that they ran the same ballots again. The same results appeared.

Caveats: This is a Twitter feed, whose claimed source is a Republican official from a different county in Georgia. Normally based on this I would not post, but the story is so shocking I thought it necessary. If true, then the elections in every state that used Dominion Machines is suspect. We will have to await confirmation however.

For those who wish to look the other way, please stop being so naive. If there is any truth to this, who cares how courts rule or states certify? The election was stolen, and a Biden presidency would begin as a lie. This story should get your blood boiling with a passionate desire to find out if it is true.

UPDATE: This Twitter feed includes some corroborating information, including a link to an independent story describing these results in the Georgia Star.

SpaceX successfully launches Dragon freighter to ISS

Falcon 9 launches Dragon freighter to ISS

Capitalism in space: SpaceX today successfully launched for the first time its upgraded Dragon freighter to ISS.

The first stage was flying its fourth flight, and successfully landed on the drone ship in the ocean. This was also SpaceX’s 100th successful launch of its Falcon 9 rocket, with about two-thirds of those flights using a used first stage.

In the cargo was also the first privately built equipment airlock, built by Nanoracks for its use in launching private payloads. This will supplement the Japanese equipment airlock on its Kibo module, both used to move equipment (not people) in and out ISS. Dragon will dock with ISS tomorrow.

The leaders in the 2020 launch race:

32 China
23 SpaceX
13 Russia
5 ULA
5 Rocket Lab
5 Europe (Arianespace)

The U.S. now leads China 36 to 32 in the national rankings.

NASA considering commercial communications satellites for Mars

Capitalism in space: NASA officials have revealed that they are considering hiring commercial communications companies to build and launch a communications network of satellites to support its Mars science missions.

In recent presentations to advisory committees, NASA officials have discussed the possibility of working with industry to place several satellites into orbit around Mars that would serve as relays for other missions, notably the proposed Mars Ice Mapper. Such satellites, they said, could greatly increase the amount of data missions can return to Earth and end reliance on aging science missions that also serve as data relays.

One proposal presented at those meetings features three satellites in equatorial orbits at altitudes of 6,000 kilometers. The satellites would be equipped with radio links for communicating with other spacecraft in orbit and on the surface as well as to and from Earth. The satellites may also include laser intersatellite links to allow them to communicate with each other.

Based on the number of missions ongoing and planned for Mars, the agency has recognized it needs to establish a dedicated system for communicating with those missions, rather than depending on the science orbiters they have in orbit. That they are looking to commercial companies to build this for them, with NASA acting merely as a customer, as an excellent sign that the agency has now completely accept this approach, as I recommended in Capitalism in Space, rather than acting as the big boss that controls everything.

China launches military surveillance satellite

China yesterday launched a military surveillance satellite using its Long March 3B rocket.

No word on whether the first stage or its strap-on boosters landed on any homes, or whether they had grid fins for better controlling their descent, as China has tested previously.

The leaders in the 2020 launch race:

32 China
22 SpaceX
13 Russia
5 ULA
5 Rocket Lab
5 Europe (Arianespace)

The U.S. still leads China in the national rankings, 35 to 32. That lead will hopefully widen in less than an hour with the first SpaceX launch of its second generation Dragon cargo freighter to ISS.

“It’s a slap in my face!”

The fascist Democratic Party mayor of Los Angeles, Eric Garcetti, issued an edict last month shutting down all restaurants, including all outdoor dining. Yet, he allowed a movie company to set up its outdoor catering services that offer the same service, in the parking lot in front of the shuttered restaurant, about-to-become bankrupt because of his edict.

But according to Angela Marsden, owner of Pineapple Hill Saloon & Grill in Sherman Oaks, local officials permitted a TV production to skirt the rules. Shockingly, the Hollywood crew had set up outdoor eating areas just feet from Marsden’s restaurant.

In her blistering rant, Marsden blasted Garcetti and Newsom for prioritizing Hollywood over small businesses like hers. “So this is my place, the Pineapple Hill Grill & Saloon. If you go to my page you can see all the work I did for outdoor dining, for tables being seven feet apart,” Marsden said. “And I come in today because I’m organizing a protest and I came in to get stuff for that.”

“And I walk into my parking lot — and obviously Mayor Garcetti has approved … this,” she continued, pointing to the production setup, including tables for outdoor dining to be used by the production crew, “has approved this being set up for…this being set up for…for a movie company.”

You must watch her video here. As she says in tears, pointing at her patio, “This is dangerous!” She then points to the movie catering area, which looks exactly the same, if not larger, less than thirty feet away. “And that is safe?” As she notes, “It’s a slap in my face!”

Remember too that this is all part of a lockdown in March that was only supposed to last 15 days, in order “to flatten the curve.” A lie, of course, as have been almost everything coming out of the mouths of government health officials since day one of this epidemic. But then, lying has become standard practice from almost every establishment official in Washington, elected or not, for the last four years, on almost every subject. Trump was colluding with Russia! He colluded with Ukraine! No one in the Obama administration ever spied on him! Trump put kids in cages (built by Obama based on Obama’s policy)! And of course, endlessly: Trump is a racist!

I could go on. They lie, and they lie again, and then they top it off with more lies.

And we are supposed to believe them when they say the vote wasn’t rigged? By this time only fools and children should accept the words out of anyone in government.

If the petty dictators in state governments don’t reconsider and stop destroying so many people’s lives, they shall soon see a lot of blood, and it will be their blood, because those same people will have no choice but to shed it in desperation. Politicians be warned.

I don’t wish it. I only know, as a historian, that this is what will happen if things don’t change soon. And if you don’t believe me you need only read a little bit of history.

Let me add that Julie Kelly says much the same in this essay: Shut up and take it. And I think she says it more thoroughly.

Chang’e-5 sample capsule docks with return vehicle in lunar orbit

According to the official Chinese state-run press Chang’e-5’s capsule containing samples from the Moon has successfully rendezvoused and docked with its return vehicle in lunar orbit, the first time an unmanned craft has done such a thing autonomously.

The news report at this point provides no other details, other than to state that the return capsule and orbiter will next separate from the ascent capsule and “wait for the right time to return to Earth.” Earlier reports had suggested an arrival on Earth around December 16, which would suggest an exit from lunar orbit in about a week.

Arizona House Speaker refuses to recall legislature to choose electors

The election has been stolen: Rusty Bowers, Arizona Republican House Speaker, has now categorically declared that he “cannot and will not” recall the legislature to review the election results and choose electors based on that, despite the Constitution’s clear language that gives the state legislature that full power.

He noted that such an action would violate the oath lawmakers took to uphold the U.S. and Arizona Constitutions, along with, “the basic principles of republican government and the rule of law if we attempted to nullify the people’s vote based on unsupported theories of fraud. Under the laws that we wrote and voted upon, Arizona voters choose who wins, and our system requires that their choice be respected.”

Bowers did, however, support an audit of the voting machines in Maricopa County to assuage concerns of tampering, but that call wasn’t taken up by Republican county officials who run elections.

So what will Bowers do if that audit discovers enough vote tampering and cheating to make the entire election suspect and unreliable? Will he, as so many Republican leaders do over and over, shake his head, whine how terrible it is, but he can do nothing? That’s what Republican leaders have been doing for decades, which of course now brings us to this moment.

Note too that Bowers is entirely wrong. Though it is traditional to let the voters decide, the actual words of the Constitution puts the decision with the state legislature. Period. It is Bowers’ responsibility by law to act.

If he does not use his power, as outlined in the Constitution (which by the way is the supreme law of the land), do not expect many Republicans to be elected in future years. First, Democrats are basically being told they have carte blanche to cheat, and cheat they will. It is also clear that the Republican leadership in the state house seems totally sanguine about the way the vote was run, and will likely do nothing to fix it come the next legislature. It took enormous pressure to get Bowers to even request this one audit of Maricopa County. He really does not appear very interested in identifying the problems and fixing them.

Second, why should anyone vote for any Republican, when it is clear they will not do anything?

With the last bit of optimism I have left, below are the phone numbers for the Republican leadership in the Arizona state legislature. If you live in Arizona, call them and tell them they are abdicating their responsibility as lawmakers. More importantly, tell them they are contributing to the fall of the American democracy by their inaction.

  • Senate President: Karen Fann, 602-926-5874
  • Senate Majority leader: Rick Gray, 602-926-5413
  • Speaker of the House: Russell Bowers, 602-926-3128
  • House Majority leader: Warren Petersen, 602-926-4136
