The Japanese unmanned lunar lander SLIM, in orbit around the Moon since December 25, 2023, has now lowered its orbit in preparation for its lunar landing attempt, now scheduled for tomorrow, January 19, 2024, with operations beginning at 10:00 am (Eastern).

The image to the right indicates the targeted landing area near Shioli Crater. The mission’s prime engineering goal is to demonstrate precise robotic landing technology, able to land a spacecraft softly on another planet within a target zone less than 300 feet across. If successful it is expected to survive for about two weeks, studying the surface below it with a multi-spectral camera but also releasing two test probes, one a hopping rover and the second a rolling spherical rover. Both carry their own science instruments.

I have embedded the live stream for tomorrow’s landing below.

Astronomical high-altitude balloon flight now exceeds two weeks

9:14 am

GUSTO's flight path as of January 18, 2024

A high-altitude stratospheric balloon, dubbed GUSTO and designed to study the interstellar medium, has now been circling the south pole over Antarctica for fifteen days.

The map to the right shows its full flight path since its launch on December 31, 2023. From the press release:

GUSTO is mapping a large portion of the Milky Way galaxy and Large Magellanic Cloud to help scientists study the interstellar medium. The observatory is transmitting the data it collects back to watchful teams on the ground as it steadily circumnavigates the South Pole around 120,000+ feet.

GUSTO is flying on a 39 million cubic-foot zero-pressure scientific balloon, which is so large it could easily fit 195 blimps inside of it. The balloon is used to fly missions for long periods of time during the Austral Summer over Antarctica. GUSTO is aiming for a NASA record of 55+ days in flight to achieve its science goals.

You can follow GUSTO’s flight in real time here.

SpaceX requests 43 acres of nearby Boca Chica State Park, offering to expand another park by 477 acres

1:52 pm

In order to “expand its operational footprint” at Boca Chica, SpaceX is asking to buy 43 acres of nearby Boca Chica State Park, and will offer as part of the purchase 477 acres adjacent to the Laguna Atascoca National Wildlife Refuge several miles to the north.

The link above includes maps showing the relative location of the properties. According to the meeting agenda for the Texas Parks and Wildlife department (TPWD), scheduled to take up this exchange next week, the commission already favors the deal.

“This acquisition will provide increased public recreational opportunities including hiking, camping, water recreation, and wildlife viewing, and allow for greater conservation of sensitive habitats for wintering and migratory birds,” the TPWD agenda stated. The agenda concludes by stating that the Commission finds that the proposed exchange is in the best interest of TPWD.

The public has been invited to comment on the deal at the meeting. Do not be surprised if we have a riot at that meeting of leftist activists protesting this deal.

A rock tadpole on Mars

A rock tadpole on Mars

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on January 11, 2024 by the left navigation camera of the Mars rover Curiosity.

The picture was highlighted in yesterday’s update from the rover’s science team, describing the team’s upcoming geological goals for the next few days.

We have observed resistant, polygonal fractures/ridges in many recent bedrock blocks. There is much speculation among the team as to the origin of these features. Hypotheses have different implications for past environments, and the polygonal fractures are therefore of high interest. As well as the polygonal fractures, there are more continuous linear veins. The relationship between the polygonal and linear fractures can also help to inform our interpretations

You can see the polygonal fractures in the full image. The thin line of rock sticking up from the tadpole illustrates one of these continuous linear veins. The material that fills the vein is obviously more resistent to erosion, so as the wind (and maybe ancient ice or water activity) scoured the rock into its tadpole shape, the vein material remained.

College professors insist all private activity in space must be regulated, by them

10:32 am

Now that private enterprise and free civilians are beginning to fly missions to space, independent of the government, “an international team of experts” have published a paper that demands that all future private activity in space be strictly regulated. From an article in the student newspaper of the University of Alberta:

Private citizens or corporations that collect data or research in space pose unique ethical concerns, Caulfield said. Previously, space travel was “largely funded by the public purse.” For example, the National Aeronautics and Space Administration (NASA) receives its funding from the United States government. Publicly funded research has to follow certain rules and there is a degree of oversight, Caulfield explained. But, “if space flight is funded primarily or largely by private companies like Blue Origin [and] SpaceX, what rules do they need to follow?”

Caulfield is Timothy Caulfield, the Canada Research Chair in Health Law and Policy and a professor in the University of Alberta’s faculty of law. He is also one of the twenty co-authors of this paper, the authors of which somehow think that because they teach at colleges they have better ethics that the owners of private space companies. Not only do they want to establish strict rules over what can be done in space, they want all research and data to be open source. The private data obtained by missions paid for by others must be available to everyone, even if they didn’t do a damn thing to get it.

These control freaks also insist that commercial space must follow standards of diversity, inclusion, and equity.

“This has been for too long dominated by old white men,” [Caulfield] said. “We’ve got to change that.”

O joy! We are here to help you! These idiots have ruined the entire academic community, making colleges worldwide cesspools of bigotry and race hate. They now want to impose their Marxist ideals to commercial space, probably because deep down they resent the fact that others are doing it and they are incapable of accomplishing anything on their own.

That Alberta’s student newspaper is all-in on these foolish ideas is especially disturbing. The students appear to have been brainwashed to accept such stupidity, and since they represent the future, it tells us what that future will be like.

Next manned mission to ISS to launch tomorrow

10:12 am

The next manned mission to ISS, a private mission by the company Axiom carrying three European astronauts and commanded by an Axiom astronaut, is presently scheduled to launch tomorrow, January 18, 2024, at 4:49 pm (Eastern).

This is a private mission by Axiom, launched on SpaceX’s Falcon 9 and flying the astronauts in its Freedom Dragon manned capsule. This will be Freedom’s third flight to ISS. The launch was originally scheduled for today, but SpaceX scrubbed the mission today in order to give it “additional time allows teams to complete pre-launch checkouts and data analysis on the vehicle.” It appears during normal prelaunch checkouts engineers found the joints between the upper stage and the capsule were not tightened the proper amount. The company decided to replace the joints, which caused this one day delay.

The crew will spend up to fourteen days at ISS.

I have embedded a live stream of the launch below.

Webb confirms the unusual shape of early galaxies as seen by Hubble

9:52 am

Earth galaxies shapes, as seen by Webb in infrared
Click for original image.

The uncertainty of science: The infrared view of the Webb Space Telescope appears to have confirmed and even underlined the unusual shapes of many early galaxies as previously seen by the Hubble Space Telescope.

Researchers analyzing images from NASA’s James Webb Space Telescope have found that galaxies in the early universe are often flat and elongated, like surfboards and pool noodles – and are rarely round, like volleyballs or frisbees. “Roughly 50 to 80% of the galaxies we studied appear to be flattened in two dimensions,” explained lead author Viraj Pandya, a NASA Hubble Fellow at Columbia University in New York. “Galaxies that look like pool noodles or surfboards seem to be very common in the early universe, which is surprising, since they are uncommon nearby.”

The team focused on a vast field of near-infrared images delivered by Webb, known as the Cosmic Evolution Early Release Science (CEERS) Survey, plucking out galaxies that are estimated to exist when the universe was 600 million to 6 billion years old.

While most distant galaxies look like surfboards and pool noodles, others are shaped like frisbees and volleyballs. The “volleyballs,” or sphere-shaped galaxies, appear the most compact type on the cosmic “ocean” and were also the least frequently identified. The frisbees were found to be as large as the surfboard- and pool noodle-shaped galaxies along the “horizon,” but become more common closer to “shore” in the nearby universe.

The galaxies also appear generally far less massive than galaxies in the near universe, which fits with the Big Bang theory that says they had less time to grow.

The press release notes that the sample size is still very small, and further observations will be required to confirm whether these shapes are common in the early universe.

Private satellite tracking companies track both China’s and the Pentagon’s X-37Bs

9:39 am

Two different commercial satellite tracking companies, LeoLabs and ExoAnalytics, are using their global network of radars and telescopes to track the movements of China’s X-37B mini-shuttle, dubbed Shenlong (“Divine Dragon” in English), as well as the Pentagon’s own X-37B, both of which launched recently.

LeoLabs activated its new radar system in Western Australia early last year. It’s now part of a 10-radar global network tracking the trajectories of satellites and debris so commercial operators can safely navigate the increasingly congested orbits. “We can see what’s happening in Low Earth Orbit because that’s where radar is dominant,” he explains. “But activity in higher orbits can be tracked with specialised optical telescopes. ExoAnalytics, a US commercial company, has 400 of these deployed worldwide, with 11 sites in Australia.”

LeoLabs’ radars are tracking Shenlong in its low Earth orbit. Since the U.S. X-37B is in a higher orbit, it is being monitored by ExoAnalytics.

Both these companies now provide satellite tracking services that were once the sole domain of the U.S. military. Not only does the military buy their information, so do private concerns in the U.S., since their networks track everything, not simply the two X-37Bs. Those unique craft however make for good press copy, and thus help both to sell their services to the world.

Note too that this is the first time I have seen a name attached to China’s X-37B. Previous reports never gave it a name.

Military awards satellite contracts worth $2.5 billion to three companies

9:25 am

The Pentagon’s Space Development Agency (SDA) today announced the award of contracts to Sierra Space, Lockheed Martin, and L3Harris for the construction of 54 reconnaissance satellites, with a total value of $2.5 billion.

The 54 satellites will form part of the SDA’s Proliferated Warfighter Space Architecture, a massive missile detection and tracking constellation in low Earth orbit that’s being built and launched in “tranches.” The trio of contracts announced today is for 18 satellites each in the Tranche 2 Tracking Layer: L3Harris’s award is worth $919 million; Lockheed Martin, $890 million; and Sierra Space, $740 million.

Last week SDA had awarded Rocket Lab its own 18-satellite contract for this constellation, worth $515 million.

The contract awards signal several major changes in the Pentagon’s space strategy. First, it is farming the work out to multiple companies, two of which (Rocket Lab and Sierra Space) are new. In the past the military relied on a very limited number of companies, all well established, with most contracts going to only one vender. New companies had great difficulties getting in the door.

Second, it is building a constellation of smallsats rather than single large satellites. Smallsats are cheaper to build and replace, and are much harder military targets to hit.

Third, though it appears the military is designing these satellites, it appears it is still shifting much of the work from it to the private sector. In other words, the Pentagon is becoming a customer instead of a builder. The result will be a healthy space industry capable of doing more for itself and the military.

Gullies and avalanches in Martian crater

Gullies and avalanches in a Martian crater
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 17, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows two significant features, both of which suggest the action of near-surface water ice to change to surface of Mars.

First are the gullies on the cliff wall, which also happens to be the interior slope of a 30-mile-wide crater. Since the first discovery of gullies on Mars, scientists have pondered their origin, with all their hypothesises always pointing to some form of water process. One popular theory [pdf] points to some form of intermittent water flow linked to long term climate cycles caused by the extreme shifts in the red planet’s rotational tilt, from 11 to 60 degrees. Another theory suggests the gullies form from the winter-summer freeze-thaw cycle and the accumulation of frost during winter.

The second feature are the three avalanche debris piles at the base of these gullies. The long extent of each suggests the avalanches flowed more like wet mud than falling rocks. If the ground here was impregnated with ice, than this look makes sense.

Indian satellite startup opens new satellite factory

9:04 am

Capitalism in space: The Indian satellite startup Pixxel has opened a new factory in Bengaluru in southern India, where it expects to ramp up satellite production in the coming years.

Bengaluru-based space data company Pixxel inaugurated its first spacecraft manufacturing facility in Bengaluru on Monday. The new facility holds significance as it targets to launch six satellites this year and 18 more by 2025, further advancing its mission of building a “health monitor” for the planet.
Spread across 30,000 square feet, the facility, at its full capacity, is equipped to handle more than 20 satellites simultaneously that can be turned around within a timeframe of six months, making possible a total of 40 large satellites per year.

The company says that its “…total customer base is divided into three divisions as of now – 40 per cent agriculture, 30 per cent resource companies, and 30 per cent government. Pixxel expects 85 per cent of the revenue to be generated from its commercial side and the rest from the government’s side by 2025.”

For India’s government and its space agency ISRO, Pixxel’s existence signals the sea-change in its policies, similar to what has been happening in the U.S. with NASA. In the past ISRO would have built the satellites. Now it is buying them from the private sector in India. That shift bodes well for India’s space industry, and will likely make it a major player in space in the coming years.

SpaceX’s Starlink: More satellites in orbit but fewer close encounters

8:56 am

According to a recent filing with the FCC, SpaceX has found its Starlink constellation had to do fewer collision avoidance maneuvers in the past six months, despite having more satellites in orbit.

In that period, Starlink satellites had to perform 24,410 collision avoidance maneuvers, equivalent to six maneuvers per spacecraft. In the previous reporting period that accounted for the six months leading up to May 31, 2023, the constellation’s satellites had to move 25,299 times. The data suggests that even though the Starlink constellation has grown by about 1,000 spacecraft in the last six months, its satellites made fewer avoidance maneuvers in that period than in the prior half year.

At the moment it is not clear why the number dropped, especially as it had been doubling every six months previously as more satellites were launched. This might signal improved more precise orbital operations, or it could simply be a normal fluctuation. It will require additional reports to get a better sense.

These numbers however should rise as more larger satellites constellations (from Amazon and China) start launching as expected.

The divide in a giant Martian lava river

The divide in a giant Martian lava river
Click for original image.

Cool image time! The photo to the right, rotated, cropped, reduced, sharpened, and annotated to post here, was taken on September 24, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

As indicated by the arrows, this is a frozen river of lava on Mars, flowing to the southwest and then splitting into two streams, one to the west and the other to the south. Being a Martian lava flow, when it was liquid it flowed much faster than lava on Earth, almost like a thick water. The flow bored into any high features, such as the two mesas in this picture, and streamlined their shapes, tearing material away as the lava moved by quickly. In the process the lava flow exposed many layers in those mesas, indicating many other previous lava flow events.

The crater in the lower mesa, where the stream splits, appears to have been more resistent to the flow, having been compacted into harder and denser material by the impact itself.

Elon Musk’s employee update released January 12th

10:19 am

I have embedded below an employee update of the status of all of SpaceX’s projects, given by Elon Musk and released publicly on January 12, 2023. The video has been edited only to remove the many enthusiastic applauses by Musk’s audience of co-workers in order to shorten it.

Though Musk provided a lot of general information about the company’s long term goals with Starlink, Starship, Mars, the Moon, and other topics, these are the most important take-aways relating to its ongoing efforts now:

  • Falcon 9: The company is now upgrading its first stage so that it will be able to fly reused forty times, not twenty. Musk also noted that they have now reused the rocket’s fairings more than 300 times.
  • They are now aiming for about 150 launches in 2024. (It appears now that the biggest obstacle to this goal will be weather, as seen by the weather delays that have stalled Falcon 9 launches this very week.)
  • The Dragon fleet has now spent more days at and flights to ISS than the NASA’s entire shuttle fleet.
  • Starlink: It is a supplement to present phone and internet service, not a replacement, serving remote areas. Its biggest obstacle now however to providing that service is government approvals. The company is blocked by regulators in many places where the service is operational.

On Starship/Superheavy, he revealed these facts:

  • They are planning to double its payload capacity to 200 tons to orbit, twice the Saturn-5.
  • Starship would have made orbit on the second orbital test if it had had a payload. To simulate the weight of payload it had carried extraoxidizer, and when it vented these as it approached orbit it caused problems that activated the self-destruct system.
  • The third orbital test flight will thus almost certainly reach orbit, and will then test engine burns, some refueling technology, payload deployment, and de-orbit procedures.

Musk emphasized that they must be able to fly these tests frequently to get Starship/Superheavy functioning, not just for SpaceX but for NASA’s Artemis program. As he said, “Time is the one true currency.” With each launch they refine the system to make it more reliable and operational. Without those launches they can’t.

He did not mention why launches might not happen frequently, probably because the last thing he needs to do is antagonize the regulators who are slowing him down. I (and other journalists) however are not under that restriction. The biggest obstacle to SpaceX’s success is the red-tape being wound around it by the Biden administration and its love of strict regulation, possibly instigated by its political hostility to Elon Musk as a person.

This government action to stymie freedom must end, and the sooner the better.

Peregrine still operational but expected to burn up in Earth’s atmosphere

9:23 am

Peregrine flight path as of January 13, 2024
Click for original image.

According to an update yesterday from Astrobotic’s engineering team, the damaged lunar lander is likely to enter the atmosphere burn up when its orbit brings it back to Earth in about a week.

In an update the day before, the company released a graph of the spacecraft’s position in relation to the Earth and Moon, shown to the right. From that update:

Peregrine remains operational at about 238,000 miles from Earth, which means that we have reached lunar distance! As we posted in Update #10, the Moon is not where the spacecraft is now (see graphic). Our original trajectory had us arriving at the Moon on day 15 post launch. Our propellant estimates currently have us running out of fuel before this 15-day mark

The plan had apparently been to circle the Earth twice in this elongated orbit, with the second orbit (after some mid-course corrections) bringing Peregrine close enough to the Moon (after it had moved further in its orbit) to be captured by its sphere of influence. With the loss of fuel due to the leak, the spacecraft doesn’t have the fuel to do any of the required engine burns, including one that would avoid the Earth’s atmosphere upon return.

Momentus delays next orbital tug mission due to lack of funds

3:24 pm

The orbital tug startup Momentus has now delayed its next orbital tug mission, scheduled to launch in March on a SpaceX Falcon 9 rocket, due to shortage of cash in the bank.

In a filing with the U.S. Securities and Exchange Commission Jan. 12, Momentus announced it did not plan to fly its next tug, Vigoride-7, on SpaceX’s Transporter-10 rideshare launch in March. The company said it called off the flight because of its “inability to support continuing operations for the expected launch date as a result of the Company’s limited liquidity and cash balance.”

The company said in November that it has signed up seven customers who planned to deploy satellites on Vigoride-7 and two other customers who would operate hosted payloads on the vehicle, but did not identify then. Momentus also intended to fly a rendezvous and proximity operations demonstration on the vehicle as part of its long-term plans for reusable tugs.

Momentus also announced the layoff of 20% of its full-time workforce, on top of the 30% layoffs which occurred in the third quarter in 2023. It appears from the SEC filing that these layoffs are a result of not winning the military contract to build its Tranche-2 constellation, won by Rocket Lab earlier this week.

The company is presently seeking new investment capital.

Another look at the increasing regulatory burden impacting commerical space

1:10 pm

Link here. The author does a nice job summarizing the problems now becoming evident as the administration state strives to expand its power and control. Though he gives space to both sides, allowing the defenders of that administrative state to explain why strong regulations are good, he doesn’t bow to those defenders, as do too many modern journalists.

That he quotes me extensively (and has has told me personally that he is a regular reader of Behind the Black), might have something to do with this. He isn’t parroting my positions, however, in this essay, but giving his own perspective.

Definitely worth reading.

A cluster of strange terrain in Martian glacier country

Overview map

A cluster of strange terrain on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 21, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this “patterned ground.” I see instead a whole range of inexplicable Martian geological features that, while each has been documented previously, each remains puzzling as to its formation process.

First there is the stucco-like peaks of all sizes on the upper left. This surface really looks like it had been wet plaster covered with Saran Wrap that had its peaks pulled up when that wrap was pulled off quickly.

Then there is brain terrain on the right. Always associated with glacier features on Mars, these convolutions are unique to Mars and as yet not entirely understood.

Next there is the circular arc on the middle left. It appears to be the remains of an impact crater now filled partly, but if so why has its northern rim disappeared so completely?

If you look close at the image above as well as the full image, you will find other mysterious features as well.

The location is the white dot on the overview map above. The rectangle in the inset shows the area covered by this picture, part of the floor of an unnamed eighteen-mile-wide and one-mile deep crater. The glacial material that appears to fill its interior as well as the splash apron that surrounds it all suggest the ground here is impregnated with water ice. Located as it is on the western end of the 2,000-mile-long north mid-latitude strip I dub glacier country — where practically every image shows glacial features — this conclusion is not surprising.

In fact, this photo illustrates well the alieness of Mars. We understand glaciers and ice, but on Mars, with its very cold temperatures, one-third Earth gravity, and thin atmosphere, those glaciers and ice are able to do things that we don’t yet understand. Untangling these geological processes will take decades of work, and likely will not be completed until people can walk the Martian surface and study it up close.

And won’t that be fun?

A new plan to send a probe to interstellar object Oumuamua

9:55 am

Project Lyra about to rendezvous with Oumuamua
Click to watch the animation.

Scientists have proposed a project to send an unmanned probe to Oumuamua, using the Earth, Jupiter, and then the Sun to slingshot onto a path that would catch up with the interstellar object on its journey leaving the solar system in the mid-2050s.

The project, dubbed Lyra, was first proposed in 2023. The scientists have now revised the plan to account for the greater speeds needed to catch up with Oumuamua as it continues to move away from us. It is still within the solar system, but it is moving away very fast.

The graphic to the right, a screen capture of an animation at the link, shows the spacecraft as it finally approaches the interstellar object in 2055. To get there it would launch in the early 2030s, slingshot past the Earth to reach Jupiter, which would then slow it down so that it would fall back to the Sun, passing it by less than 450,000 miles, which would slingshot it out to Oumuamua (with the help of an additional engine burn). To survive the close solar approach it would use the same technology used by the Parker Solar Probe, which has already successfully flown that close to the Sun.

It seems this is an entirely worthwhile project, since Oumuamua continues to baffle scientists as to its nature. While most belief it is a natural but very unusual interstellar asteroid, none can dismiss the possibility that it instead an alien spacecraft. The data precludes nothing. Getting close to it seems worthwhile, no matter what.

For me, that rendezvous will happen when I would be 102 years old. I don’t think I’ll be here to see it.

Japan’s H2A rocket launches military surveillance satellite

9:24 am

Japan’s H2A rocket today successfully launched a new military surveillance satellite designed to observe North Korean’s missile launch sites.

The live stream of the launch is here, cued to T-10 seconds.

New reports had previously reported the last launch of the H2A occurred in September 2023, launching Japan’s SLIM lunar lander and XRISM X-ray telescope. This was obviously incorrect. Today’s launch appears to close out the H2A manifest, leaving Japan rocketless until it can get both its new H3 and grounded Epsilon rockets operational.

Boeing completes Starliner parachute drop test

9:13 am

Boeing on January 9, 2023 successfully completed a parachute drop test of its Starliner capsule, testing whether the redesigned connection between the chutes and the capsule was now meeting proper safety specifications.

The drop test, which used a Starliner parachute system attached to a dart-shaped sled the same weight as a Starliner, was performed to confirm the functioning of a redesigned and strengthened soft link joint that is part of the network of lines connecting the parachutes to the spacecraft. The test also validated a change to strengthen one textile joint in the parachute, increasing overall parachute robustness. As with other capsules, Starliner relies on parachutes to land safely when it returns to Earth.

Engineers are still analyzing the results, though the parachutes worked as planned. The first manned mission of Boeing’s commercial capsule is now scheduled for April 2024, only four years late as well as four years after SpaceX accomplished the same thing. It still remains staggering that the company did not find out about that soft link joint when it was designing the capsule, instead of only months before the first manned mission last year. It is not as if the use of parachutes to land capsules is cutting edge technology.

Double-ringed crater near the Starship landing zone on Mars

Double-ringed crater
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on September 10, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label simply as a “double-rim crater.”

If you look close you might not be unreasonable to call this instead a triple-rim crater, as there appear to be two rings on each side of the highest crater rim.

Multple rings in craters are not rare. We see many on the Moon. Most however are associated with very large impacts, and are an expression of the ripples formed at impact, not unlike the ripples seen when you drop a pebble in water. Unlike water ripples, the ripples formed in rock are impact melt that quickly refreezes, thus capturing those ripples as concentric rings.

In this case, these rings likely signal not freezing rock but freezing ice.

Fauci: Now an admitted liar as well as incompetent scientist

12:47 pm

Fauci: Washington's top liar
Anthony Fauci: the liar-in-chief during
the Wuhan panic

This week Anthony Fauci was brought before a committee in the House of Representatives for closed-door hearings on his actions during the COVID epidemic in 2020-2021. Though supposedly private, the committee has been providing detailed recaps of Fauci’s testimony.

What it has learned is that Fauci was not only a chronic liar during his time as director of the National Institute of Allergy and Infectious Diseases (NIAID), he was also utterly incompetent as both a scientist as well as an administrator.

None of this really is news. As early as December 2020 Fauci admitted publicly that he had purposely misstated facts and scientific data for political reasons. Repeatedly I have reported many other examples of his dishonesty and incompetence (see for example these posts from June ’21, April ’22, September ’22, November ’22, and September ’23).

Nonetheless, Fauci’s testimony now is worth reviewing, because it underlines starkly how he misled and misinformed the public, causing great harm for no gain.

First, he admitted in testimony that the demands by him and the government that everyone maintain a six-foot distance during the epidemic was utter garbage, based on no scientific data at all.

In Tuesday’s session, Fauci admitted that the six-foot social distancing recommendation “was likely not based on any data,” according to the committee. “It just sort of appeared,” it wrote, quoting Fauci.

In August 2020 I found evidence suggesting the only source for this absurd rule came from a high school science project. Fauci has now essentially confirmed this, admitting that there is no legitimate science behind the six-foot rule.
