Today’s blacklisted American: Liberal black journalist Juan Williams for not being “black enough”

12:15 pm

Blacklists are back and PBS has got ’em: He might be liberal, a Democratic Party cheerleader, and black, but that didn’t stop a PBS host from blacklisting television pundit Juan Williams from appearing on his show because Williams was simply not “black enough”.

Williams alleges the host is on the PBS-affiliated show “This Is America & The World” and that he declined to have Williams talk about race-related issues because he was born in Panama, not America. Williams, a Democrat, said he received a note from the show host telling him about his decision.

“A white TV host recently dismissed me from appearing on his show to discuss race relations by telling me I didn’t qualify because I was born in Panama,” Williams said in his opinion piece in The Hill. “He thinks I’m not Black enough. Seriously.”

When you make race and skin color your number one criteria in all your decisions, then you will begin to make insane and very bigoted decisions like this. Ideas no longer matter. Nor does talent or skill. Only skin color determines who you like or dislike. The only thing that makes this particular example of the left’s constant blacklisting of others for racial reasons different is that it was aimed at a Democrat and a moderate leftist who also happens to not fit the exact racial measure they needed for their narrative.

Nor is this the end. The demand to judge people based solely on their race or ethnicity and the unwillingness of most people to challenge it is leading us directly to race war. Sooner or later the oppressed are not going to take it anymore, especially when some of those oppressed are highly qualified and will view their subjugation as unjust and will have the brains to do something about it.

Americans of all colors have got to start standing up and defying these bigots, loudly. It is the only way we can prevent that race war, and bring us back to the free society we have been for most of the last half century.

NASA’s choice of Starship proves government now fully embraces capitalism in space

11:50 am

Five years ago, before Donald Trump had even announced he was running for president, before Elon Musk had proposed his Starship/Superheavy rocket, and even before SpaceX had successfully begun to dominate the launch market, Jerry Hendricks at the Center for for New American Security (CNAS) asked me to write a policy paper on the state of the American launch industry, providing some background and more importantly, some recommendations that policy makers in Washington, dependent on that launch industry, could use as guidance in the coming years.

CNAS is a Washington, D.C., think tank that was founded in the middle-2000s by two political Washington insiders, one a Democrat and the other a Republican, with a focus on foreign policy and defense issues and the central goal of encouraging bi-partisan discussion. Hendricks’ area of focus was defense and aerospace matters, and at the time he thought the changes being wrought by SpaceX’s with its partly reusable Falcon 9 rocket required in-depth analysis. He had heard my many reports on this subject on the John Batchelor Show, and thought I could provide him that analysis.

The result was my 2017 policy paper, Capitalism in Space: Private Enterprise and Competition Reshape the Global Aerospace Launch Industry. In it I reviewed and compared what NASA had been getting from its parallel rocket programs, the government-designed and owned Space Launch System (SLS) rocket versus the privately-designed commercial rockets of SpaceX and Orbital ATK (now part of Northrop Grumman). That review produced this very simple but starkly revealing table:

SLS vs Commercial space

From this data, combined with my extensive knowledge as a historian of American history and culture, resulted in the following fundamental recommendations:

Study: U.S. mortality rates suggest background radiation actually beneficial

9:10 am

The uncertainty of science: According to a new study by researchers at Ben-Gurion University in Israel of mortality rates across the entire United States, people that live in regions of higher background radiation have lifespans on average 2.5 years longer.

Background radiation is an ionizing radiation that exists in the environment because of natural sources. In their study, BGU researchers show that life expectancy is approximately 2.5 years longer among people living in areas with a relatively high vs. low background radiation. Background radiation includes radiation emanating from space, and radiation from terrestrial sources. Since the 1960s, there has been a linear no-threshold hypothesis guiding policy that any radiation level carries some risk. Hundreds of billions of dollars are spent around the world to reduce radiation levels as much as possible.

…According to BGU Professors Vadim Fraifeld and Marina Wolfson, along with Dr. Elroei David of the Nuclear Research Center Negev, lower levels of several types of cancers were found when the radiation levels were on the higher end of the spectrum rather than on the lower end. Among both men and women, there was a significant decrease in lung, pancreatic, colon and rectal cancers. Among men, there were additional decreases in brain and bladder cancers. There was no decrease in cervix, breast or prostate cancers or leukemia.

Their data “covered the entire US population of the 3139 US counties, encompassing over 320 million people,” according to their paper’s abstract.

Up until now the assumption has been that any radiation is bad, based not on research but on assumptions gained by the negative consequence of exposure to high radiation. There has been no good data on the consequences of low level background radiation, because it is so hard to gather. The time frames are long and the numbers small, all of which causes the impact of background radiation to be overwhelmed by other factors. This study’s statistical use of the entire U.S. population is an attempt to overcome these obstacles.

This study is statistical, which means it found a correlation between higher radiation and longer lifespans. Correlation however does not prove causation. The study found no direct evidence that humans health benefits from background radiation. We should therefore take these results with a large grain of salt.

At the same time, their extremely large database is quite telling, and adds some weight to their conclusion.

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.

Amazon signs ULA’s Atlas 5 for first 9 Kuiper satellite launches

4:51 pm

Capitalism in space: Amazon today announced that it has signed a launch contract with ULA to use its Atlas 5 rocket for the first 9 Kuiper satellite launches.

The announcement did not say when these flights will take place, nor how many Kuiper satellites will be on each. Amazon’s license with the FAA requires that it launch half its 3,200 satellite constellation by ’26. Also ULA intends to retire the Atlas 5 in only a few years, replacing it with its Vulcan rocket. This suggests that the launches will occur in the next three years.

They better. Starlink is already going operational, and OneWeb is about to. Plus several other internet constellations are in the pipeline. If Amazon wishes to compete it needs to get those satellites in orbit as quickly as possible. Internet customers don’t generally change their servers easily, tending to stick with whom they’ve got. If Starlink and OneWeb scoop up all the best low-hanging internet fruit Amazon will find itself facing an uphill battle getting customers.

The article revealed one tidbit of interest. Rajeev Badyal, Amazon’s VP of technology for the Kuiper project, was one of the managers Elon Musk fired from his Starlink project in 2018 after realizing that that management team was moving far too slowly for his tastes. It appears Jeff Bezos then hired Badyal to run Kuiper.

Mask madness even as scientists confirm once again their uselessness

2:51 pm

Even as a just published new study has shown once again the utter uselessness of masks to limit the spread of respiratory diseases like COVID-19, the control freaks of our now largely oppressive society are clamping down with new totalitarian rules requiring masks to be worn at all times, no matter what.

First let ‘s look at the study, which was published by the National Center for Biotechnological Information government website, a branch of the National Institute for Health. From the paper:

The physical properties of medical and non-medical facemasks suggest that facemasks are ineffective to block viral particles due to their difference in scales. According to the current knowledge, the virus SARS-CoV-2 has a diameter of 60 nm to 140 nm [nanometers (billionth of a meter)], while medical and non-medical facemasks’ thread diameter ranges from 55 µm to 440 µm [micrometers (one millionth of a meter), which is more than 1000 times larger. Due to the difference in sizes between SARS-CoV-2 diameter and facemasks thread diameter (the virus is 1000 times smaller), SARS-CoV-2 can easily pass through any facemask. In addition, the efficiency filtration rate of facemasks is poor, ranging from 0.7% in non-surgical, cotton-gauze woven mask to 26% in cotton sweeter material. With respect to surgical and N95 medical facemasks, the efficiency filtration rate falls to 15% and 58%, respectively when even small gap between the mask and the face exists.

Clinical scientific evidence challenges further the efficacy of facemasks to block human-to-human transmission or infectivity. A randomized controlled trial (RCT) of 246 participants [123 (50%) symptomatic)] who were allocated to either wearing or not wearing surgical facemask, assessing viruses transmission including coronavirus. The results of this study showed that among symptomatic individuals (those with fever, cough, sore throat, runny nose etc…) there was no difference between wearing and not wearing facemask for coronavirus droplets transmission of particles of >5 µm. Among asymptomatic individuals, there was no droplets or aerosols coronavirus detected from any participant with or without the mask, suggesting that asymptomatic individuals do not transmit or infect other people. This was further supported by a study on infectivity where 445 asymptomatic individuals were exposed to asymptomatic SARS-CoV-2 carrier (been positive for SARS-CoV-2) using close contact (shared quarantine space) for a median of 4 to 5 days. The study found that none of the 445 individuals was infected with SARS-CoV-2 confirmed by real-time reverse transcription polymerase.

There is a lot more in the study. Read it all. It shows, based on extensive research, that even when worn properly masks are relatively useless in stopping viral diseases. And since as mandated no one ever uses them properly, they end up becoming likely collectors of pathogens instead, at the very spot where people breath, thus contributing to the spread of infection.

The study also documented the numerous physiological and psychological costs caused by the forced continuous use of masks, from restricting oxygen to causing people to become socially isolated.

The paper’s conclusion:

Spring arrives on the northern polar cap of Mars

1:37 pm

Buzzell dunes and pedestal crater near the Martian north polar ice cap
Click for full image.

Cool image time! It is now spring in the northern hemisphere of Mars, and the first bits of sunlight are finally reaching its north polar ice cap. During the winter, as happens each Martian year, that polar cap of water ice gets covered by a thin mantle of dry ice no more than six feet thick. Moreover, this mantle doesn’t just cover the ice cap, it extends south as far as about 60 degrees latitude, covering the giant sea of dunes that surrounds the ice cap.

When spring comes that mantle begins sublimate away, with its base first turning to gas. When the pressure builds up enough, the gas breaks out through the frozen mantle’s weakest points, usually the crest or base of dunes or ridges, leaving behind a dark splotch caused by the material thrown up from below that contrasts with the bright translucent dry ice mantle.

Each year for the past decade scientists have been using the high resolution camera on Mars Reconnaissance Orbiter (MRO) to monitor this sublimation process. The photo above, taken on February 24, 2021 and cropped, enlarged, and brightened to post here, marks the start of this year’s monitoring program. Dubbed informally “Buzzell” by Candice Hansen of the Planetary Science Institute in Arizona, it shows dunes with a round pedestal crater just right of center. Though almost everything when this picture was taken is still covered by that dry ice mantle, in the lower left is a single splotch, the first breakout of CO2 gas that marks the beginning of the annual disappearance of this dry ice.

Last Martian year I repeatedly posted images of Buzzell to illustrate this annual process. The second image below was taken on April 4, 2019, at about the same comparable time in spring.

Today’s blacklisted American: Anyone who is white, Christian, or male at Cigna

Cigna training presentation
According to Cigna’s training, these are bad things.

They’re coming for you next: Company documents as well as interviews have confirmed that the health insurance company Cigna actively discriminates against whites in its hiring practices, as well as runs training sessions using Critical Race Theory that aims at making all whites, males, and Christians ashamed of what they are, because by definition such people are automatically racist bigots.

Boeing confirms next Starliner unmanned demo flight delayed until August

9:25 am

Capitalism in space: Boeing on April 17th confirmed what had already been rumored, that the second unmanned demo flight to ISS of Starliner, its manned capsule, has been delayed until August.

In a statement, Boeing said that the company and NASA are projecting the uncrewed Orbital Flight Test (OFT) 2 mission will take place in August or September. That date is “supported by a space station docking opportunity and the availability of the United Launch Alliance Atlas V rocket and Eastern Range.”

Boeing had been working toward a launch of OFT-2 in late March or early April. However, by early March, NASA officials acknowledged that was no longer likely because of delays from the replacement of avionics units on the spacecraft that were damaged by a power surge during ground tests, as well as power outages in the Houston area caused by a winter storm in February that interrupted software testing.

They still hope to make the first manned demo flight before the end of the year, assuming the summer unmanned flight goes as planned.

For Boeing, the sooner they get this capsule operational, the sooner it can start earning money by flying commercial flights. At the moment the delays have meant that SpaceX is getting all that business, with two private flights already scheduled and rumors that it will win a flight from the UAE as well. Furthermore, other commercial competitors are on the horizon, including both China and India.

Starship prototype #15 readying for flight, possibly tomorrow

9:13 am

Starship #15 on launchpad
Screen capture from Labpadre launchpad live stream.

Capitalism in space: SpaceX’s 15th prototype of its Starship upper stage, is preparing to do a static fire test today, with its first test flight possibly as soon as tomorrow, though at present the FAA has not given its approval.

They have done tank tests already, and installed three upgraded Raptor engines yesterday. This spacecraft is a major upgrade from the previous prototypes, and SpaceX probably plans to eventually fly it higher and farther than the previous prototypes. Though no details about those flight plans has yet been released, the first flight will almost certainly repeat the previous flights, going up about ten miles, flipping sideways to simulate a controlled atmospheric descent, and then uprighting itself and landing vertical on the landing pad. Hopefully the upgrades will result in the first truly clean landing with this prototype.

Though the FAA under the Biden administration has seemed eager to flex its bureaucratic muscles and slow development, that NASA has chosen this vehicle as the one that will take astronauts to and from the Moon will put pressure on it to not slow things down too much.

Ingenuity flies!

8:53 am

Ingenuity takes off!
For full images go here and here.

The first autonomous flight of the helicopter Ingenuity on Mars successfully took place early this morning, according to JPL engineers.

NASA has pulled off the first powered flight on another world. Ingenuity, the robot rotorcraft that is part of the agency’s Perseverance mission, lifted off from the surface of Mars on 19 April, in a 40-second flight that is a landmark in interplanetary aviation. “We can now say that human beings have flown a rotorcraft on another planet,” says MiMi Aung, the project’s lead engineer at the Jet Propulsion Laboratory (JPL) in Pasadena, California.

As shown by the two images taken by Perseverance above, the first flight was very simple. The helicopter simply rose about 10 feet, hovered for about 30 seconds as it swiveled 90 degrees, and then carefully descended back down. I have also embedded the video that JPL scientists have created compiling by high resolution Perseverance images below the fold.

Four more flights will next be attempted in the coming weeks.

Four further flights, each lasting up to 90 seconds, are planned in the coming weeks. In these, Ingenuity is likely to rise up to 5 metres [16 feet] above the surface and travel up to 300 metres [1000 feet] from the take-off point. Each successive flight will push Ingenuity’s capabilities to see how well the drone fares in Mars’s thin atmosphere, which is just 1% as dense as Earth’s.

Click for higher resolution. For original images, go here and here.

Some cool images to savor from Mars! Above is a panorama from Curiosity, created by me from two images taken by the rover’s left navigation camera today, April 18, 2021. The view is southwest towards the canyon regions where Curiosity will be heading in the coming months. Note the roughness of the ground. Travel is going to be tricky from here on out.

The photo was taken from the top of Mont Mercou, the 20-foot high outcrop that the rover spent several weeks studying at the cliff’s base. The Curiosity science team is presently preparing to drill into the bedrock at the top.

The photo to the right, reduced to post here, was taken by Perseverance on April 13, 2021, and looks west across the floor of Jezero crater. The high mountains in the distance are the crater’s rim. The low and much closer hill is the delta that is the rover’s primary geological target.

In the center of the picture is the helicopter Ingenuity. You can also see the tracks of Perseverance’s wheels just below it.

This will be the rover’s vantage point when Ingenuity attempts its first test flight in the early morning hours of April 19, 2021. The helicopter will head to the right once it lifts off.

Ingenuity first test flight scheduled for 3:30 am (Eastern) tonight!

8:16 am

The engineering team for the Ingenuity helicopter on Mars have decided to attempt the first test flight tonight, scheduled for 3:30 am (Eastern) in the early morning hours tomorrow.

Data from the first flight will return to Earth a few hours [later] following the autonomous flight. A livestream will begin at 6:15 a.m. EDT (3:15 a.m. PDT) as the helicopter team prepares to receive the data downlink in the Space Flight Operations Facility at NASA’s Jet Propulsion Laboratory (JPL).

NASA propaganda will begin on NASA TV at 3:30 am (Eastern), but the actual live stream of the flight will not air until about 6:30 am (Eastern) on April 19th.

At the first link above the engineers explain their decision to proceed immediately.

Russia hands over last rocket engines to ULA

9:20 am

In a ceremony in Russia yesterday, Roscosmos’s Energomash division completed and handed over ownership to ULA six RD-180 engines, to be used in ULA’s Atlas 5 rocket.

These are the last such engines required as part of the contract. They will also likely be the last Russian engines ULA will ever buy. The company is retiring its Atlas 5 rocket, which requires them, and replacing it with its Vulcan rocket, which will instead use Blue Origin’s BE-4 engine.

Furthermore, as of September 1st, 2021 such commercial space contracts with Russia will be difficult to obtain because of new sanctions imposed on Russia by the Biden administration.

Ingenuity successfully completes rapid spin test

9:00 am

Ingenuity’s engineers announced this morning that yesterday the helicopter on Mars was able to successfully complete a rapid spin test of its rotary blades.

Today, April 16, on the 154th anniversary of Wilbur Wright’s birth, the Ingenuity flight team received information that the helicopter was able to complete a rapid spin test. The completion of the full-speed spin is an important milestone on the path to flight as the team continues to work on the command sequence issue identified on Sol 49 (April 9).

…The approach that led to today’s successful spin test entailed adding a few commands to the flight sequence. This approach was tested extensively on both Earth and Mars, and was performed without jeopardizing the safety of the helicopter.

They have still not set a date for flight, because they might still decide, after they have analyzed fully the results from this test, to revise the helicopter’s software and upload that change. If not the flight will be relatively soon. If so there will be a longer delay to test that software fully before flight.

SpaceX wins competition to build Artemis manned lunar lander, using Starship

1:58 pm

Starship prototype #8 on first flight test
Starship prototype #8 on its first flight test,
December 2020

Capitalism in space: NASA has just announced that it has chosen SpaceX to build the Artemis manned lunar lander, using Starship.

The award, a $2.9 billion fixed price contract, also requires SpaceX to complete an unmanned demo lunar landing with Starship that also returns to Earth, before it lands NASA astronauts on the Moon. The contract also still retains the goal to get this to happen by 2024, though NASA official emphasized that they will only launch when ready.

After these flights the agency says it will open bidding again to the entire industry, which means that others are now being challenged to come up with something that can beat SpaceX in the future.

Nonetheless, the contract award was a surprise, as NASA originally intended to pick two teams to provide redundancy and encourage competition. Instead, the agency completely bypassed lunar landers proposed by Dynetics and a team led by Blue Origin that included Lockheed Martin and Draper.

Even more significantly, though NASA explained in the telecon that they still plan to use SLS and Orion to bring astronauts to Gateway, who will then be picked up by Starship for the landing, this decision is a major rejection of the Space Launch System (SLS), since Starship will not use it to get to the Moon, while the other two landers required it.

In fact, this decision practically makes SLS unnecessary in the Artemis program, as NASA has also awarded SpaceX the contract for supplying cargo to the Lunar Gateway station as well as launching its first two modules, using Dragon capsules and Falcon Heavy. SLS is still slated to launch Orion to Gateway, but Starship can replace Orion as well, since Starship is being designed to carry people from Earth to the Moon. This makes SLS and Orion essentially unneeded, easily abandoned once Starship starts flying.

NASA’s decision also means the Biden administration is willing to use its clout to push for Starship over SLS in Congress, which has favored SLS for years because of the pork it brings to their states and congressional districts. They apparently think that Congress is now ready to risk the end of SLS if it comes with a new program that actually accomplishes something. These developments firmly confirm my sense from February that the political winds are bending away from SLS.

This decision is also a major blow to Blue Origin and the older big space companies that Jeff Bezos’ company partnered with. Their dependence on the very costly and cumbersome SLS rocket meant that their ability to launch on a schedule and cost desired by NASA was severely limited. NASA looked at the numbers, and decided the time was right to go with a more radical system. As was noted by one NASA official during the press teleconference, “NASA is now more open to innovation.”

Based on the details announced during the announcement, NASA was especially drawn to Starship’s payload capability to bring a large payload to the Moon, at the same time it brings humans there as well. It also appears SpaceX’s recent track record of success also added weight to their bid.
