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.

Smothers Brothers – Hippie Chick Clip

6:01 pm

An evening pause: A wonderful moment from the 1960s, performed brilliantly by actress Leigh French and resulting in some wonderful and gentle satire of the hippie culture of the time. Context is also important, because the Smothers Brothers were constantly having problems with their television censors.

Hat tip Judd Clark.

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.
