CDC admits the uselessness of masks against COVID-19

9:41 am

In issuing its guidelines for dealing with the smoke coming from the numerous forest fires in California, the CDC on August 30th admitted the complete uselessness of masks in stopping the coronavirus.

From the CDC:

Cloth masks that are used to slow the spread of COVID-19 offer little protection against wildfire smoke. They do not catch small particles found in wildfire smoke that can harm your health.

As the author at the first link above notes,

Let’s take a quick look at this info through the lens of actual science. They just told us that smoke particulates are too small to be stopped by a cloth mask. While N95 masks will protect up to 95% of particles, down to .1 microns in size, a quick Google search will tell us that smoke particles and debris are usually .4 to .7 microns in size. According to the CDC, cloth masks are not effective in stopping materials that size.

Another quick Google search will tell us that the Wuhan Virus is .12 microns in size, about a quarter in size of the smoke and fire debris particulate. Even if we factor for the “respiratory droplets” that are allegedly to blame for the spread of coronavirus, those droplets are as small as .5 microns, or as small or smaller than smoke and fire debris particulate. These factors and figures aren’t hidden in some CDC vault that only their scientists are capable of accessing. Yet another quick Google search will show these figures within seconds.

The masks you are using can’t protect you, period. They are nothing more than an empty feel-good gesture imposed for political reasons. Worse, their improper use, something that people are doing routinely, will increase the chances of infection from all kinds of pathogens, including COVID-19.

Stop wearing these idiotic things. And if anyone challenges you, tell them you don’t wear it for justified medical reasons. Most local rules allow for this exemption, and do not require any explanation. Use it. Stop being a sheep to stupidity.

September 11, 2001 through the Eyes of a Child

9:27 am

Link here. The horror of that terrorist act, no different than the horrifying acts of rioting and looting dressed up as fake protests today, should not be forgotten. This article gives us possibly the most important perspective, the impact that horror had on the innocent children of the time.

Matthew John Bocci wrote the book Sway as a way to sort out his feelings. He was nine years old when his father died during the collapse of the World Trade Center. It took one week for the family to find out his father was dead. “Even though I knew he was dead, I still needed to find out the how. I became obsessed. I wondered if he had jumped, since he worked on the 105th floor and I saw all the smoke. My thoughts were that if he had jumped, maybe I could see him looking out a window beforehand. Even though I found out my dad did not jump, when I see the footage, it brings a lot of sadness. I look at it and think my father was in that building and he never had a chance to get out. In the book, I wrote, ‘What could you say, especially to a nine-year-old whose father was obliterated?'”

He went on to say, “My dad was selfless. He actually called my mom two minutes after the plane hit the building to tell her he loved her and us. He said goodbye. I now try to look at the positives he left behind. He was honorable, put family first, and was very humble. I think how brave he was, smart, resourceful, funny, determined, hardworking, and caring.”

Because of his father’s death, Matthew’s life spiraled out of control. He searched for answers and a father figure. Unfortunately, his Uncle Phil filled that role. He took advantage of Matthew’s grief by sexually abusing him. To cope, Matthew turned to drugs. But thankfully, after many years of drug abuse, he got himself straightened out, had his uncle arrested and convicted of child abuse, and is now five years sober.

To my mind, the worst result of both 9/11 and today’s riots is our society’s generally weak response. We never really did wipe out the scourge of Islamic terrorism after 9/11, which since then has only worsened. For children like Matthew, who lost his father, there is thus no closure or a feeling of justice.

And today we seem paralyzed to act against the home-grown terrorists in our midst, allowing them to commit some equally ugly acts while doing little to stop them. We must therefore ask ourselves, what are today’s children learning from this failure?

For evil to flourish good men need only do nothing. And sadly nothing is much of what America has been doing for the past two decades.

Japan delays launch of new rocket one year

8:58 am

Capitalism in space: Because of a problem discovered in the development of its new first stage engine, Japan has now delayed the first launch of its new H3 rocket one year, to ’21.

Mitsubishi is building the rocket for Japan’s space agency JAXA, Since you design and build your rocket around your rocket engines, having a problem with that rocket engine puts a serious crimp on construction. Thus, identifying and dealing with such engine issues early in development is wise.

Still, Japan continues to lag behind the other space-faring nations in the development of its space industry.

Astra scrubs launch attempt

8:50 am

Capitalism in space: The smallsat rocket company Astra yesterday scrubbed another attempt to achieve its first orbital launch.

They were forced to stand down at T-25 minutes because of a sensor issue. No further details were released, nor have they as yet announced a new launch date.

This launch will be the third for Astra, following two flights from the Pacific Spaceport Complex Alaska in July and November 2018, respectively. These flights were originally believed to be failures. However, Astra stated that the first (designated Rocket 1.0) was successful and that the second (Rocket 2.0) was “shorter than planned.” Neither rocket was designed to reach orbit, as they did not have functioning upper stages.

This scrubbed flight has been dubbed Rocket 3.0, and was part of what the company calls a three launch program aimed at reaching orbit by the third launch. All three launches are orbital, but the company has made it clear that it would not be surprised if the first or even the second failed.

NASA to buy lunar mined material from private companies

8:43 am

Capitalism in space: NASA yesterday announced that, rather than develop its own lunar sample missions, it wants to buy such lunar mined material obtained from private companies.

NASA on Thursday launched an effort to pay companies to mine resources on the moon, announcing it would buy from them rocks, dirt and other lunar materials as the U.S. space agency seeks to spur private extraction of coveted off-world resources for its use.

NASA Administrator Jim Bridenstine wrote in a blog post accompanying the announcement that the plans would not violate a 1967 treaty that holds that celestial bodies and space are exempt from national claims of ownership.

The initiative, targeting companies that plan to send robots to mine lunar resources, is part of NASA’s goal of setting what Bridenstine called “norms of behavior” in space and allowing private mining on the moon in ways that could help sustain future astronaut missions. NASA said it views the mined resources as the property of the company, and the materials would become “the sole property of NASA” after purchase.

This announcement continues NASA’s transition under the Trump administration from trying to run everything to simply being a customer buying what it needs and wants from the private sector. The idea is smart, as it will guarantee that these samples will be obtained in the cheapest and fastest way possible, while simultaneously sparking the development of a competitive and thriving private industry capable of flying all kinds of planetary missions. The lower costs of these private planetary probes will in turn will spark the creation of a new private sector of customers buying those probes for their own profit-centered needs.

John Ford’s The Searchers

6:01 pm

An evening pause: A very detailed look at some of the behind-the-scenes history for one of John Ford’s best westerns, The Searchers (1956), starring John Wayne.

This isn’t my favorite Ford film. I prefer My Darling Clementine (1946). Nonetheless, The Searchers is still one of the best, and this short documentary will also give you a feel for the actual American culture of the time, a culture that cared about the truth and tried to treat people with respect.

If you want to watch but save time, you can set the playing speed at 2X normal and understand everything completely.

Hat tip Tom Biggar.

Boeing strikes deal to avoid harsher ethics probe in NASA’s lunar lander scandal

3:07 pm

Boeing has struck a deal with both NASA and the Air Force in order to avoid a harsher and more extensive ethics probe into its part in the NASA lunar lander contract bidding scandal.

The agreement, signed in August, comes as federal prosecutors continue a criminal investigation into whether NASA’s former human exploration chief, Doug Loverro, improperly guided Boeing space executive Jim Chilton during the contract bidding process.

By agreeing to the “Compliance Program Enhancements”, the aerospace heavyweight staves off harsher consequences from NASA and the Air Force – its space division’s top customers – such as being suspended or debarred from bidding on future space contracts. The agreement calls for Boeing to pay a “third party expert” to assess its ethics and compliance programs and review training procedures for executives who liaise with government officials, citing “concerns related to procurement integrity” during NASA’s Human Landing System competition.

Since Loverro resigned in May, Boeing has fired one company attorney and a group of mid-level employees, three people familiar with the actions told Reuters.

The deal seems like a bureaucratic whitewash, designed to take the heat off the company. And since Boeing as a company has many problems, I remain skeptical that any of this will make a difference in getting things fixed.

ULA pinpoints cause of Delta launch abort, reschedules launch

2:58 pm

ULA has identified the cause of the launch abort of its Delta 4 Heavy rocket on August 29th, and has now aiming for a launch no earlier than September 18th.

A torn diaphragm in one of three pressure regulators at Cape Canaveral Air Force Station’s Launch Complex 37 caused the computer-controlled scrub just three seconds before liftoff on Aug. 29, ULA CEO Tory Bruno said via Twitter on Wednesday. The engines briefly lit on fire, but the rocket remained firmly on the pad.

“Torn diaphragm (in the regulator), which can occur over time,” Bruno said. “Verifying the condition of the other two regulators. We will replace or rebuild as needed, re-test, and then resume towards launch.” [emphasis mine]

The highlighted words illustrate the less than stellar old space rocket design that the Delta 4 Heavy represents, and that ULA is perpetuating as long as it uses this rocket. Rather than redesign so that these torn diaphragms will no longer be a problem, it appears they will simply make sure this design is tested and works, for this launch. Thus, this issue has the possibility of reappearing in a future launch.

Wouldn’t it be better to upgrade and eliminate such a problem, for good, once it is identified? That appears to be SpaceX’s strategy, and the consequence is that their rockets and spacecraft get increasingly more reliable with time.

Anyway, if ULA’s schedule holds, it means there will be two launches at Cape Canaveral in less than 24 hours, as SpaceX is aiming for another Starlink launch the day earlier.

Northrop Grumman shuts down Omega rocket program

2:49 pm

Having lost any chance of getting launch contracts or development money from the military for the next five-plus years, Northrop Grumman has chosen to shut down its Omega rocket program.

“We have chosen not to continue development of the OmegA launch system at this time,” Northrop Grumman spokeswoman Jennifer Bowman said in a statement. “We look forward to continuing to play a key role in National Security Space Launch missions and leveraging our OmegA investments in other activities across our business.”

Bowman said the company will not be protesting the U.S. Space Force’s decision to select United Launch Alliance and SpaceX for the NSSL contracts.

This was a typical big space Washington project, aimed solely at getting government contracts, as well as government cash to develop it. The company had no interest in trying to develop it with its own R&D funds in order to garner market share in the general launch market, or even to make it cheaper and more useful to the military than SpaceX’s rocket.

In this sense this is no great loss. What we need is real competition, aimed at coming up with better ideas that will lower cost and increase capabilities. What Northrop Grumman was offering was none of those things. It was fake competition, and of no real value.

Texas sees 400% increase in homeschooling

11:42 am

The silver lining? Faced with odious rules and remote zoom classes in the public education system due to fear and terror over the corona virus, Texas parents are choosing to homeschool their children this year, with the numbers rising by 400%.

The spike, the group reported, stems directly from the Texas Education Agency’s (TEA) pandemic schooling guidelines sparking a mass exodus from the public school system as parents opt to teach their children at home over enrolling them in a digitized, remote state-run classroom.

Our government public schools have been corrupted by leftist indoctrination for years, while they have steadily done a worsening job at educating children in the basics. (Witness for example the ignorance exhibited by the Antifa protesters about American history.) Maybe this disaster created by the Wuhan flu panic might have some benefits, such as getting parents more involved once again in their kid’s education, and thus improve it.

Because, based on everything I’ve seen and read about modern public school education and culture, parents really can’t do worse.

Sharp Martian ridges sticking up from the dust

10:35 am

Sharp ridges sticking up from Martian dust
Click for full image.

Today’s cool image brings us back to the region of Mars where the rover Opportunity journeyed. Taken on June 25, 2020 by the high resolution camera on Mars Reconnaissance orbiter (MRO), the photo to the right, cropped and reduced to post here, focuses on some sharp but low ridges that appear to stick up out of the Martian dust, hinting that they are the tops of some larger feature buried over the eons and only now revealed partly by recent erosion. I estimate that their height is roughly one to two hundred feet or so.

This image is in Arabia Terra, the widest and largest transitional zone region between the northern lowland plains and the southern cratered highlands. It is also only about 200 miles north of where Opportunity landed, and about 230 miles from where it died after almost fifteen years of operation, on the west rim of Endeavour Crater. The overview map below gives the context.
