Florida proves (again) the stupidity of mask mandates

12:58 pm

On September 25, 2020 the Republican governor of Florida, Ron De Santis, lifted all mandates on mask use while ending all restrictions on restaurants

He was immediately lambasted by numerous Democratic Party Florida mayors as well as:

Dr. Anthony Fauci, who warned that the change is “very concerning to me. When you’re dealing with community spread, and you have the kind of congregate setting where people get together, particularly without masks, you’re really asking for trouble.”

The mayor of Miami Beach, Democrat Dan Gelber, was especially harsh, stating in a letter to De Santis that

The Navy’s overreaction to COVID-19

12:09 pm

On October 10th the press breathlessly reported that “nearly two-thirds of the Navy’s deployable warships have endured COVID-19 outbreaks”.

What was not mentioned was the number of sailors killed by the outbreaks. Though the NAVY report says nothing about mortality, it does say this:

Sailor rates of infection are generally the same as the rates of infection in the local area. … Within the uniformed Navy population, roughly 35 percent of infected sailors exhibit few to no symptoms. This should build confidence in the ship’s ability to fight through outbreaks.

I strongly suspect that practically no one has died yet from coronavirus on a Navy ship. In fact, this sounds exactly like a typical flu season, where the flu quickly spreads among those confined in close quarters, but then peters out shortly thereafter, forgotten.

In other words, COVID-19 in the Navy (as elsewhere) is really nothing more than a variation of the flu, possibly more infectious to all and more harmful to the elderly sick, but harmless to practically everyone else.

The bad part of this is that, rather than let the disease play out quickly so that crews are promptly immune and the epidemic no longer can effect efficiency — as humanity has done for eons — the Navy is panicking like everyone else, instituting strict quarantines on all those infected, plus social distancing and mask rules. All this will do is prolong the agony, and interfere with the Navy’s operation. You can’t run a ship or a submarine realistically if you require everyone to keep six feet distance at all time.

NASA charging Estee Lauder $17,500 per hour for filming its perfume on ISS

11:00 am

Capitalism in space: It now appears that NASA is charging Estee Lauder $17,500 per hour for filming the perfume that was just brought to ISS on the most recent Cygnus freighter.

The cosmetics giant will pay $17,500 per hour for the astronauts to take photos of their serum in space. Coincidentally — or not — the Space Station orbits the earth at 17,500 miles per hour.

The International Space Station is an orbiting laboratory for scientific research, but it’s the photo ops and viral videos that capture the public’s imagination.

Estée Lauder will get video and photos of their out-of-this-world product in the most photographed spot on the space station — the Cupola. The photos are not to be used in print or television advertising, but instead on social media, according to NASA. The astronauts won’t be using the product or be featured in the pictures.

The article also notes that NASA is dedicating 5% of astronaut time to commercial activities. Sooner or later I think NASA is also going to have to start paying their astronauts for this work. They deserve their share of the proceeds.

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.

A lunar landslide

10:03 am

Landslide on the Moon
Click for full image.

Cool image time! The image to the right was posted by the Lunar Reconnaissance Orbiter (LRO) science team on October 9, 2020, and shows a spectacular landslide almost a mile and a half long that had occurred on the interior rim of a crater on the Moon.

The top of the rim is on the left, with the landslide breaking out onto the floor of the crater on the right.

The walls of Kepler crater (30 kilometer diameter) exhibit numerous landslides. In this example, a landslide of dark material begins about 100 meters below the rim from a narrow box canyon. The box canyon is about 50 meters wide and 300 meters long. Overall, the slide is extends some 2300 meters (from the end of the canyon to its base). The base of the slide is on a fault block that lies some 1800 meters below the rim. The wall slope is about 33 degrees.

This slide is actually composed of a series of narrow landslides 20-30 meters wide. Along most of the slope, the individual slides overrun each other forming a band of debris up to about 180 meters wide. At the base of the slope, the individual slides can be recognized as they move apart forming a fan of material. A few individual isolated slides also occur adjacent to the main mass. The overlapping nature of these small slides indicate that the overall feature may have formed over a period of time, rather than all at once.

From above and at this resolution, the landslide looks almost like frozen flowing liquid. It allso looks like it began with a scattering of boulders breaking free at the top all at once that quickly consolidated into a single massive avalanche.

At the link you can zoom in or out to look at the entire image, at full resolution.

SpaceX begins installing Raptor engines on Starship prototype #8

9:47 am

Capitalism in space: With Starship prototype having successfully passed its tank tests SpaceX has begun installing three Raptor engines in preparation for static fire tests followed by a 50,000 foot high hop.

Once the Raptors are installed, Starship SN8 is expected to undergo an extensive test program, opening with fueling tests, a spin prime test, and preburner tests, before the first Static Fire test.

That opening Static Fire test will be the first time three Raptors have been fired up simultaneously.

Once that opening Static Fire test has been completed, a data review will be conducted on engine performance and related systems – such as the Ground Support Equipment (GSE) – which will allow the nosecone to be installed on to SN8 at the launch site.

At that point the prototype will be ready for its hop. Based on the pace SpaceX is setting (and assuming all goes well), this flight should occur sometime in the next month, possibly at almost the same time as the next manned Dragon flight to ISS.

A mile-long trail of human footprints about 12,000 years old

9:41 am

Scientists have found in New Mexico a mile-long trail of human footprints from about 12,000 years ago that was probably left by a woman and toddler.

Even more interesting, the tracks show that the woman (or male adolescent) retraced her route, without the child.

Unlike many other known footprint trackways, this one is remarkable for its length – over at least 1.5km [almost a mile] – and straightness. This individual did not deviate from their course. But what is even more remarkable is that they followed their own trackway home again a few hours later.

Each track tells a story: a slip here, a stretch there to avoid a puddle. The ground was wet and slick with mud and they were walking at speed, which would have been exhausting. We estimate that they were walking at over 1.7 metres per second – a comfortable walking speed is about 1.2 to 1.5 metres per second on a flat dry surface. The tracks are quite small and were most likely made by a woman, or possibly an adolescent male.

At several places on the outward journey there are a series of small child tracks, made as the carrier set a child down perhaps to adjust them from hip to hip, or for a moment of rest. Judging by the size of the child tracks, they were made by a toddler maybe around two years old or slightly younger. The child was carried outward, but not on the return.

There is also evidence of a mammoth and sloth crossed the tracks in-between the outward and return journey, with the sloth apparently sensing the human tracks or presence.

Zvezda both leaking and heating up

9:23 am

A Russian news source today reported that the temperature in the ISS module Zvezda has been increasing even as air has been leaking slowly from it.

The article provides little additional detail, other than saying that “normal temperature should be restored” by today.

Why the module should be warming as it slowly leaks air is puzzling. Either way, as this is a module that has been in space for twenty years and is also a key component in the station’s operations, locating the leak is crucial. It might simply be caused by a micrometeorite hit, which can be easily patched. Or it could be caused by something more fundamental, caused by the module’s age, and thus more difficult, possibly even impossible, to fix. If so, the sooner engineers know the better.

China’s Long March 3B launches another remote sensing satellite

11:47 pm

China today (October 11) successfully used its Long March 3B rocket to place another remote sensing satelle into orbit.

No word on whether the first stage and its strap-on boosters landed on any homes, or if they were equipped with fins to guide their re-entry.

The leaders in the 2020 launch race:

26 China
16 SpaceX
10 Russia
4 ULA
4 Europe (Arianespace)

With this launch China moves back into a tie with the U.S., 26-26, in the national rankings.

Next manned Dragon launch delayed

11:54 pm

Because of an engine issue that caused Falcon 9 launch of a military GPS satellite to abort at T-2 seconds on October 2nd, SpaceX and NASA have decided to delay the next manned Dragon launch from October 31st “to early-to-mid November.”

The one to two week delay will give the company time to analyze the issue involving an “unexpected pressure rise in the turbomachinery gas generator” that are used to drive the rocket’s Merlin engine turbopumps.

It seems unlikely that this problem is systemic to all Merlin engines, considering the number of rocket launches SpaceX has successfully completed in the last four years. Each launch has used ten engines, with no evidence of this problem appearing previously.

At the same time, no one wants a problem on a manned flight. Better to completely understand why it happened on the GPS launch first before launching four astronauts on the rocket.
