Retractions of peer-reviewed scientific papers has risen 13,750% in this century

11:47 pm

Modern peer review in science
Modern peer review in science

The present and growing dark age: According to the watchdogs who run the website Retraction Watch, the number of peer-reviewed scientific papers that have been retracted each year has risen from 40 in 2000 to 5,500 in 2022, an astonishing increase of 13,750%.

According to these watchdogs, there are two reasons for this increase in research failure:

Retractions have risen sharply in recent years for two main reasons: first, sleuthing, largely by volunteers who comb academic literature for anomalies, and, second, major publishers’ (belated) recognition that their business models have made them susceptible to paper mills – scientific chop shops that sell everything from authorships to entire manuscripts to researchers who need to publish lest they perish.

These researchers are required – sometimes in stark terms – to publish papers in order to earn and keep jobs or to be promoted. The governments of some countries have even offered cash bonuses for publishing in certain journals. Any surprise, then, that some scientists cheat?

I think the watchdogs are missing the major and much more basic source for this problem. » Read more

SpaceX launches another 22 Starlink satellites

10:27 pm

In what is turning into routine clockwork, SpaceX tonight completed its fourth launch in only the first ten days of August, placing 22 Starlink satellites into orbit using its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its ninth flight, landing safely on a drone ship in the Atlantic. The two fairings completed their tenth and eleventh flights respectively. At the time of posting the satellites themselves had not yet been deployed.

The leaders in the 2023 launch race:

55 SpaceX
33 China
11 Russia
6 Rocket Lab
6 India

American private enterprise now leads China in successful launches 63 to 33, and the entire world combined 63 to 55. SpaceX by itself is now tied with the entire world (excluding American companies) 55 to 55.

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, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, 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

Russia launches Luna-25 to the Moon

5:20 pm


Click for interactive map.

After almost two decades of development, Russia today used its Soyuz-2 rocket to launch Luna-25, its first lander to the Moon since the 1970s.

The link is cued to the live stream, just prior to launch. It will take several days to get to the Moon and enter orbit, make some orbital adjustments, then land in Boguslawsky crater, as shown on the map to the right. It is likely its landing will occur before India’s Chandrayaan-3 lands on August 23rd but not certain, depending on the adjustments needed in lunar orbit. Both could even land on the same day.

The leaders in the 2023 launch race:

54 SpaceX
33 China
11 Russia
6 Rocket Lab

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.

Today’s blacklisted American was fired for refusing to participate in company’s programs that purposely excluded whites

12:50 pm

Cancelled at Compass Group
Cancelled unilatiterally by Compass’ management

They’re coming for you next: Courtney Rogers, who was fired as a human resources employee from the large food services company Compass Group because she refused to participate in any way with its “whites-need-not-apply” training and mentoring programs, has now filed suit against the company.

You can read her complaint here [pdf], filed by her attorneys working with the non-profit legal firm, the Thomas More Society. The introduction of that complaint outlines clearly the bigotry of Compass’s management and the policies it wished to install, as well as Rogers sincere and futile effort to not participate in this segregation and discrimination:

In early 2022, COMPASS—one of the largest companies in the world—devised a “diversity” program that it misnamed “Operation Equity.” The program offered only women and persons of color the opportunity to participate in training and receive mentorship, with a promise of guaranteed promotion.

The program’s accurate name would have been “White-Men-Need-Not-Apply.” The program was motivated by racial animus against white men held by certain members of COMPASS’s senior management. COMPASS executives like JOANN CANADAY, Vice President of Human Resources Operations (Canteen), and RALENA ROWE, Vice President of Talent Acquisition, stated that the program was intended to “right the wrongs of the last hundred years.” And they threatened would-be opponents of their program: “This is the direction the world is going, jump on the train or get run over.” And they proclaimed: “We are not here to appease the old white man.” Of course, RALENA ROWE and JOANN CANADY anticipated that “There would be a homogenous group of people against this program,” and they planned to draft a response to objections made by people in that “homogenous” group.

The icy mountains close to where SpaceX hopes to land Starship on Mars

The icy mountains near Starship's landing site on Mars
Click for original image.

Cool image time! The photo to the right, rotated, cropped, reduced, and sharpened to post here, was taken on June 25, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled as showing “flow features” by the scientists, it gives us a nice example of many of the different types of glacial and near-surface ice features seen routinely in the Martian latitudes above 30 degrees, especially in the northern hemisphere.

First there is the apron around the mound. Its layering suggests the many cycles that Mars’ climate has undergone as its rotational tilt swung back and forth from as low as 11 to as much as 60 degrees (it is presently at 25 degrees).

The mound, with those two depressions at its peak, suggests the possibility that it is some form of ice/mud volcano, similar to the suspected ice/mud volcanoes routinely seen in the northern lowland plains of Utopia Basin.

Juno gets new close-up images of Jupiter’s moon Io

9:57 am

Io as seen by Juno in July 2023
Click for original image.

During its July close fly-by of Jupiter the orbiter Juno also flew past the moon Io, getting within 14,000 miles. The picture to the right, cropped and reduced to post here, was one of the images taken during that fly-by and subsequently processed and color enhanced by citizen scientist Thomas Thomopoulos.

The picture was taken at about the spacecraft’s closest point. It shows the splotched and volcanic surface of Io, which because it orbits close to Jupiter tidal forces cause it to have an intensely active volcanic surface. All the black features are either volcanoes or lava flows. This set of all of Juno’s Io images taken during the fly-by, enhanced by citizen scientist Gerald Eichstädt, also shows a volcanic plume in the shadowed portion of the planet, just beyond the terminator, which Eichstädt believes is a mountain dubbed Tohil Mons.

Even closer flybys are scheduled for December ’23 and February ’24, both getting within 1,000 miles of the surface.

Astronomers: Binary system creates tidal waves on star’s surface 3x larger than our own Sun

9:32 am

Tidal waves on star's surface

Based on computer simulations, astronomers believe that the monthly light changes in a binary star system are partly caused by gigantic tidal waves on the surface of the system’s larger star, waves that are three times higher than the diameter of our own Sun.

The larger star in the system is nearly 35 times the mass of the Sun and, together with its smaller companion star, is officially designated MACHO 80.7443.1718 — not because of any stellar brawn, but because the system’s brightness changes were first recorded by the MACHO Project in the 1990s, which sought signs of dark matter in our galaxy.

Most heartbeat stars vary in brightness only by about 0.1%, but MACHO 80.7443.1718 jumped out to astronomers because of its unprecedentedly dramatic brightness swings, up and down by 20%. “We don’t know of any other heartbeat star that varies this wildly,” says MacLeod.

To unravel the mystery, MacLeod created a computer model of MACHO 80.7443.1718. His model captured how the interacting gravity of the two stars generates massive tides in the bigger star. The resulting tidal waves rise to about a fifth of the behemoth star’s radius, which equates to waves about as tall as three Suns stacked on top of each other, or roughly 2.7 million miles high.

The image on the right is a screen capture from the computer simulation. The bulges on the right side of the larger star are the hypothesized tidal waves.

Update on the development of a new first stage for Northrop Grumman’s Antares rocket

9:01 am

Link here. The first stage of the Antares rocket has previously relied on Russian engines in a Ukrainian-built body. The Ukraine War made getting both impossible, and thus Northrop Grumman hired Firefly to provide it a new first stage, presently targeting mid-2025 for its first flight. In the meantime in order to meet its contractual obligations with NASA, it has hired SpaceX’s Falcon 9 rocket to fly the next three Cygnus freighters to ISS.

The report at the link gets some interesting details about Firefly’s engines and first stage. Both will raise the payload capabilities of Antares, which as yet has failed to garner any commercial payloads outside of Northrop’s own Cygnus capsule. That increase in capability might make it more appealing to commercial satellite companies.

Chinese pseudo-company Galactic Energy launches seven satellites

8:52 am

China's spaceports
China’s spaceports

One of China’s pseudo-companies, Galactic Energy, yesterday successfully placed seven small satellites into orbit, using its Ceres-1 solid-fueled rocket that lifted off from China’s Jiuquan spaceport in the Gobi Desert.

Considering that a launch two days ago from the Taiyuan spaceport apparently dropped sections of its first stage near habitable areas, I though it worthwhile to post again the map to the right, showing which Chinese spaceports expose China’s inhabitants to risk.

It also appears that even the state-run press of China knows Galactic Energy really isn’t a privately owned commercial company, as it doesn’t even mention the company’s name in its news report at the link. While it gets investment capital and functions kind of like a private company, everything it does is supervised by the Chinese government, which can take full control of the company whenever it wants. Moreover, the technology of its solid-fueled rocket was derived entirely from military technology, which means the Chinese government supervised its development every step of the way.

The leaders in the 2023 launch race:

54 SpaceX
33 China
10 Russia
6 Rocket Lab
6 India

American private enterprise still leads China in successful launches 62 to 33, and the entire world combined 62 to 54, while SpaceX by itself is now tied the world (excluding American companies) 54 to 54.

Pushback: Judge rules that libel suit against two black professors for slandering white real estate assessor can proceed

12:38 pm

Mott (l) and Connolly, eager to defame whites
Mott (l) and Connolly, eager to use race to
defame an innocent white man

Bring a gun to a knife fight: A U.S. district judge on August 2, 2023 ruled [pdf] that the defamation lawsuit of real estate assessor Shane Lanham against two black Johns Hopkins professors can now proceed.

And boy, does Lanhan stand a good chance of winning. This is a followup of an earlier blacklist story from February. The two professors, Nathan Connolly and Shani Mott, had publicly accused Lanham on national television of being a bigot because they had not liked the value he placed on their house. As I wrote then:

This story began when Connolly and Mott asked Lanham (who is white) and his company, 20/20 Valuations, to appraise their house. When they were unhappy with his appraisal, they decided to get another appraisal, but this time do what they themselves called a ““whitewashing experiment.” For the second appraisal they removed all evidence that a black family owned the house, to the extent of having a white friend present himself as the owner instead. The second appraisal, done months later, came up with a higher price.

Martian craters or volcanoes?

Martian craters or volcanoes?
Click for original image.

Cool image time! The picture to the right, cropped and reduced to post here, was taken on June 30, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The scientists label these features “cones” because many of the depressions sit on top of a mound or hill, suggesting some form of volcanic feature, either from erupting lava, ice, or mud.

Yet, are they volcanoes? Some or even many could instead be impact craters, created when a asteroid broke up during infall, creating a spray of bolides. Erosion of surrounding terrain can create what scientists call pedestal craters, but if all these craters were from an impact than all would either be pedestal craters, or not. Instead, we have a mix of some craters above and others level with the terrain.

Ingenuity snaps picture of Perseverance during 54th flight

Perseverance as seen by Ingenuity on August 8th
Click for original image.

During Ingenuity’s 54th flight, a short vertical hop sixteen feet up and down that lasted only 25 seconds, the helicopter’s color camera managed to get a picture of the rover Perseverance, only about 200 feet away to the north.

That picture, cropped and enhanced to post here, is to the right. It shows Perseverance just inside the picture’s upper edge. Its graininess illustrates in a sense the engineering test nature of Ingenuity. It was never expected to last this long and to take actual scouting or science imagery. It was supposed to complete a 30 day program of a handful of test flights, proving it was possible to fly in Mars’ very thin atmosphere (1/1000th that of Earth). Instead, it has lasted years, and completed 54 flights, keeping ahead of Perseverance and providing the rover team scouting images of the ground they wish to travel.

South Korea’s KARI space agency releases new images taken by its Danuri lunar orbiter

10:02 am

To celebrate the anniversary of its launch, South Korea’s KARI space agency today released new images taken by its Danuri lunar orbiter.

Images include views of Reiner Gamma, a so-called swirl, which features a localized magnetic field and marks a bright spot within the Oceanus Procellarum region. Another shows shadows inside Amundsen Crater, close to the lunar south pole and a potential landing site for NASA’s Artemis 3 mission, which is slated to put astronauts on the moon in late 2025.

Another southern feature captured by Danuri is Drygalski Crater, showing the central peak inside the impact crater.

ESA official confirms first Ariane-6 launch will not occur until 2024

9:45 am

The head of ESA yesterday confirmed what had been known since May, that the first test flight of its Ariane-6 rocket will not take place this year but will be delayed until 2024.

In an update on the Ariane 6 program also posted Tuesday, the ESA said that it could not complete a short hot firing test — which mimics the environment in space to provide data to operators — of Ariane’s Vulcain 2.1 engine system in a July attempt, with plans to try again on August 29.

Aschbacher said the tentative plan is to carry out a long hot fire test of the assembled core stage and engine on September 26 at the agency’s spaceport in French Guiana. If those tests are successful, it should then be possible to set a more precise timeline for getting the rocket system ready for launch next year.

It seems the inability of engineers to complete that July engine test — which ESA officials claimed was because they simply ran out of time — added at least a six-week delay to the entire program.

There delays leave Europe without any large rocket to launch payloads, and has forced its various governments to hire SpaceX to get those payloads into space.

First stage of Chinese rocket crashes in Chinese city

9:34 am

Remains of Long March 2C, in Chinese city

Locals in the city of Shangluo, population over two million located in central China, today released video images of the remains of the first stage of a Long March 2C rocket that launched yesterday and apparently crashed in the city.

The image to the right is a screen capture. Since this two-stage rocket uses extremely toxic hypergolic fuels in both of its stages, those citizens wandering around the rocket’s remains are in great health danger.

China has in recent years has appeared taken actions to block the release of such videos by its citizens, but apparently failed in this case.

The irony is that this rocket supposedly launched what China called “a disaster reduction” satellite. That maybe so, but in the process it also dumped toxic materials on its own citizens.

NASA engineers still struggling to understand why Orion’s heat shield ablated so much

9:10 am

NASA engineers still do not understand why the heat shield on its Orion capsule ablated as it did during its return to Earth on the first unmanned Artemis-1 mission.

The agency is still running tests. It also expressed confidence that the issue will not delay the Artemis-2 mission, the first intended to carry humans on SLS and in Orion and still scheduled for late 2024.

At the same time, agency officials hinted that the third Artemis mission, which has always been planned as putting humans on the Moon for the first time since Apollo, might not achieve that goal. It is still not clear whether the mission’s lunar spacesuits as well as SpaceX’s Starship lunar lander will be ready on time. The latter is facing serious regulatory problems imposed by the Biden administration that is generally preventing it from flight testing the spacecraft.

That second Artemis mission, the first planned to carry humans, is one that actually at present carries the most risk. It will not only use a heat shield that at present engineers do not entirely understand, it will be the first Orion capsule to have the environmental systems necessary for its human cargo. NASA is putting humans on the first test flight of those systems.

  • According to NASA the investigation into the Soyuz/Progress coolant leaks continues

    • It appears Russia still favors micrometeorite impacts as the cause, but no possibilities have been dismissed. If Russia concludes it was sabotage or some failure in the coolant system design, do not expect any public information release, though Russian officials might tell NASA officials, under an agreement that NASA will help Russia keep this info secret.

NOAA lifts many restrictions on the release of commercial Earth observation images

3:09 pm

As part of a 2020 revision by Commerce to reduce regulations on satellites that monitor the Earth, NOAA has now lifted many of the restrictions it placed on the release of high resolution commercial Earth observation images.

NOAA said it lifted 39 restrictions on an unspecified number of licenses. Those restrictions include a reduction of global imaging restrictions for certain imaging modes and removal of restrictions on non-Earth imaging and rapid revisit. It also removed all temporary conditions on X-band synthetic aperture radar (SAR) imagery.

One of the companies that benefits from the removal of the conditions is SAR imaging company Umbra. The company announced Aug. 7 that, with the removal of the conditions, it can now offer SAR images to customers at a resolution of 16 centimeters, compared to no better than 25 centimeters under the old license conditions. “This means that we are finally able to offer customers the highest resolution images that our satellites are capable of capturing, setting the stage for even further expansion of products to customers,” said Gabe Dominocielo, Umbra’s co-founder and president, in a company statement.

The revision to the regulations, put in place in 2020, had been instigated by the Trump administration, and has apparently been left untouched by the Biden administration, at least up until now.

For the satellite companies it means they are much freer to produce that best imagery, and thus compete more successfully. For customers, it means that they will now have access the best imagery, in open competition. For news outlets attempting to report on things like the Ukraine War, for example, this ability will make it possible to improve the accuracy of the coverage.

Real pushback: Judge slams Southwest Airlines for violating settlement terms of free-speech court case

1:38 pm

Southwest: Enemy to free speech

Bring a gun to a knife fight: We now come to another chapter in the continuing saga of flight attendant Charlene Carter, who was fired in 2017 by Southwest Airlines because she had expressed opinions that were not liked by both the company and union officials. In 2022 a jury awarded her $5.1 million against the airline and the union.

In December 2022 the federal judge in the case, Brantley Starr, reduced the settlement award to $810,000 in order “to comply with federal limits on punitive damages.” However, he also approved the rest of the jury award, which required Southwest to rehire Carter as well as change its policies that violated the first amendment, and announce these facts publicly to its employees.

Only a month later Carter went back to court, demanding that the judge sanction Southwest for violating settlement terms of her court victory. Not only did the company not admit error to its employees, as required by the settlement, one company-wide memo slandered Carter again, calling her previous communications for which she was fired as “inappropriate, harassing, and offensive.”

Judge Starr yesterday responded to Carter’s demand for relief, slamming Southwest in no uncertain terms.

Land of Martian springs?
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on December 22, 2014 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). I came across this image when researching another photo taken recently of the interior of this same 56-mile-wide crater, dubbed Firsoff, and decided this decade old picture was far more interesting.

Firsoff, which had been considered a candidate landing site for Perseverance, is known for the many layers shown in this picture. It is also known for having mounds, here ranging in height from 90 to 150 feet, that some scientists believe could have once been springs of water. The layers as always are of great interest, as they provide data on past geological events. In the case of Firsoff, the layers are especially easy to see because of their alternating dark and light colors. The dark layers are thought to be basalt, suggesting these layers were laid down during a volcanic event.

Scientists repeat fusion power experiment that produced more energy than spent

10:03 am

For the second time ever, scientists have successfully produced more energy from a fusion power experiment than they spent running the experiment.

Physicists have since the 1950s sought to harness the fusion reaction that powers the sun, but until December no group had been able to produce more energy from the reaction than it consumes — a condition also known as ignition.

Researchers at the federal Lawrence Livermore National Laboratory in California, who achieved ignition for the first time last year, repeated the breakthrough in an experiment on July 30 that produced a higher energy output than in December, according to three people with knowledge of the preliminary results.

Before you start buying stock in fusion power or believe the glowing praises coming from politicians and government bureaucrats, be warned: This experiment, which cost billions, was only able to produce enough power to run a household iron for about an hour. It will likely take many more billions and decades more of research to scale it up to a viable power system that has any hope of being practical.

Ingenuity completes 54th flight, a short hop after previous flight ended prematurely

9:45 am

Overview map
Click for interactive map.

According to the Ingenuity engineering team, Ingenuity has successfully completed its 54th flight on Mars, a short 25 second hop up and down that was done to try to figure out why the previous flight previous flight, #53, had ended prematurely.

Flight 53 was planned as a 136-second scouting flight dedicated to collecting imagery of the planet’s surface for the Perseverance Mars rover science team. The complicated flight profile included flying north 666 feet (203 meters) at an altitude of 16 feet (5 meters) and a speed of 5.6 mph (2.5 meters per second), then descending vertically to 8 feet (2.5 meters), where it would hover and obtain imagery of a rocky outcrop. Ingenuity would then climb straight up to 33 feet (10 meters) to allow its hazard divert system to initiate before descending vertically to touch down.

Instead, the helicopter executed the first half of its autonomous journey, flying north at an altitude of 16 feet (5 meters) for 466 feet (142 meters). Then a flight-contingency program was triggered, and Ingenuity automatically landed. The total flight time was 74 seconds.

This explains why, after the 53rd flight, the engineering team had not immediately added that flight to the helicopter’s flight log. That log is now updated to include both the 53rd and 54th flights, but the data from the 53rd flight was held back until after the 54th flight was completed.

The green dot in the overview map above shows Ingenuity’s present position, only a few feet to the west from its previous position shown here. The blue dot indicates Perseverance’s present position. The red dotted line indicates the planned route of the rover.

Startup orbital tug company signs deal from startup solar panel company

9:26 am

The new orbital tug company Atomos has now signed a deal with the new solar panel company, Solestial, to use the latter company’s solar panels in its tugs.

Neither company has yet flown anything in space, though both have contracts and demo missions scheduled.

Atomos plans to test a small Solestial photovoltaic panel on an orbital transfer vehicle demonstration set to launch on a SpaceX Transporter rideshare flight in early 2024. Solestial also will supply large solar blankets for two Atomos’ solar-electric OTVs slated to begin flying in late 2024 or early 2025.

Once again, these two companies illustrate the growth in the satellite industry produced by the lowering of launch costs. With less capital required to get to orbit, there is a larger margin for profit, thus encouraging companies with new ideas.
