Pushback: Home appraiser sues professors who called him racist without evidence

defame an innocent white man

Bring a gun to a knife fight: A home appraiser, Shane Lanham, who was publicly accused by two Johns Hopkins professors, Nathan Connolly and Shani Mott, of being a bigot and racist by valuing their home less because they are black, has now filed a countersuit, noting that the accusation was based on data so faulty “a first-year undergraduate” would immediately reject it.

[T]heir claims would fail to pass basic academic muster if treated as scholarship, Lanham argued in his counterclaim, which includes a suit for defamation. The racism claims achieved national coverage such as in ABC News. The resulting allegations have harmed Lanham’s business and reputation, according to the lawsuit.

“Dr. Connolly and Dr. Mott’s ill-conceived ‘experiment’ involving different appraisers, a seven-month gap, and intervening changes in market conditions would not withstand even basic scrutiny in the serious academic environment in which they work,” Lanham’s counterclaim stated. The lawsuit noted that the professors “failed to disclose the sale of the similar house next door to their home that sold only a month after Mr. Lanham and 20/20 Valuations’ appraisal for $7,000 less than the amount of the appraisal.”

You can read Lanham’s countersuit here [pdf]. He is requesting, at a minimum, $250K in compensatory damages and $250K in punitive damages.

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.

Solar Orbiter captures Mercury crossing in front of the Sun

Solar Orbiter spots Mercury in front of the Sun
Click for full movie.

The European probe Solar Orbiter successfully filmed Mercury as it crossed in front of the Sun — from the spacecraft’s perspective — on January 3, 2023.

The transit was captured by several different instruments on Solar Orbiter, as shown at the link. The picture above is a screen capture from the short movie made by its Extreme Ultraviolet Imager. The black disk is Mercury, moving from the left to the right. In the background the limb of the Sun can be seen, with a distinct feature flaring out from that limb.

For Solar Orbiter, this particular transit offered a valuable chance to calibrate the instruments. “It is a certified black object travelling through your field of view,” says Daniel Müller, Solar Orbiter Project Scientist at ESA. Thus, any brightness recorded by the instrument within Mercury’s disc must be caused by the way the instrument transmits its light, called the point spread function. The better this is known, the better it can be removed. So be studying this event, the quality of the Solar Orbiter data can be ever further improved.

If the transit also produced some spectacular images, so much the better.

VLT takes picture of exoplanet

9:20 am

VLT's picture of exoplanet
Click for original image.

The ground-based Very Large Telescope (VLT) in Chile has successfully taken a picture of an exoplanet four to six times larger than Jupiter that is circling its star at about the same distance as Saturn.

That picture, cropped to post here, is to the right. Other data from other observatories had suggested the star AF Leporis, 87.5 light years away, might have an exoplanet, so astronomers decided to focus VLT on it to see if it could spot it.

AF Leporis is about as massive and as hot as the sun, ESO wrote in the statement, and in addition to its one known planet the star also has a disk of debris similar to the solar system’s Kuiper Belt. AF Leporis is, however, much younger than the sun. At 24 million years old, it is about 200 times younger than our star. This young age makes AF Leporis and its planetary system especially intriguing for astronomers as it can provide important insights into the evolution of our own solar system.

To snap this picture, the VLT had to use adaptive optics to smooth out the fuzziness produced by the Earth’s atmosphere, while also blocking out the star’s own light (as shown by the black disk in the image).

China’s continued silence about Zhurong suggests Mars rover is dead

9:05 am

Zhurong's ground-penetrating radar data
The data from Zhurong’s ground-penetrating radar instrument.

Overview map
Zhurong’s final location is somewhere in the blue circle.

China’s continued silence about Zhurong — which should have come out of hibernation sometime in late December-early January — suggests the Mars rover did not survive the Martian winter, which this year was also lengthened near the end by some additional dust storms.

Zhurong went into hibernation in May 2022, at the start of winter, with plans to awaken in December. Like the helicopter Ingenuity and the lander InSight, it depends on solar power, and had to contend with a very relatively severe winter dust season this Martian year.

Even though the Chinese press has loudly touted Tianwen-1’s first two years in Mars orbit, it has made little or no mention of Zhurong, a silence that is deafening.

The silence is also foolish, because China has nothing to be ashamed of concerning Zhurong. The mission was only supposed to operate for 90 days. Instead it lasted more than a year, traveling much farther than planned. Most important, the data from its radar instrument (shown above) showed that, at this location at 25 degrees north latitude, there is no underground ice to a depth of 260 feet. That data confirmed that the Martian equatorial regions below 30 degrees latitude are very dry, with any underground ice existing rarely if at all. The icy regions above 30 degrees latitude do not appear to extend much farther south than that latitude.

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: Georgetown Law School tried to destroy a student simply because he asked questions about its COVID jab and mask policies

Georgetown Law School's Dean Bill Treanor
Dean Bill Treanor: He uses 1984 as
his instruction manual

They’re coming for you next: When student William Spruance gave a speech challenging the COVID jab and mask policies at Georgetown Law School, which required for example masks on students but not on teachers, university officials attempted to not only cancel him from the college, they tried to destroy him entirely.

They not only suspended him from the campus (thus preventing him from attending classes), they demanded he undergo a psychiatric evaluation while also waiving his right to medical confidentiality. On top of this, they threatened to report him to state bar associations if he did not cooperate fully.

The story at the link, written by Spruance, has a lot more horrifying nuance. Rather rehash it completely, I strongly advise my readers to go there and read it all. This quote though justifies fully Spruance’s reasonable skepticism of Georgetown’s irrational Wuhan flu policies:

Splashed lava from a Martian impact

Splashed lava from a Martian impact
Click for original image.

Almost always it is impossible to understand a high resolution image from Mars Reconnaissance Orbiter (MRO) unless you also take a wider view. Today’s cool image to the right, rotated, cropped, reduced, and sharpened to post here, is a perfect example.

Taken on January 6, 2023, it shows what the science team labeled as a “rocky deposit on crater floor.” To my eye however none of this appeared tremendously rocky. Instead, what I saw was a curved and layered flow feature whose ancient age was suggested by the many later craters scattered across its surface.

Still, its origin was unclear. It isn’t ice, not only because of its apparent resistance from disturbance from those later crater impacts but because it is located at about 20 degrees north latitude, in the dry equatorial regions of Mars. If lava, what is its source? As I noted, a wider look was necessary to answer that question.

For the 4th time Curiosity’s drill fails to penetrate marker layer

9:44 am

Failed drillhole by Curiosity in marker layer
Click for original image.

For the fourth time this past weekend Curiosity’s drill was unable to penetrate the hard rock of what scientists have labeled “the marker layer”, a distinct feature seen at approximately the same elevation at many places on the flanks of Mount Sharp on Mars.

The image to the right, cropped and reduced to post here, shows that the drill was once again only able to drill a eighth to a quarter inch, not enough to gather samples for testing.

This was our fourth attempt to drill this marker band, and we gave it our best shot from both a geology and engineering perspective. Unfortunately these rocks do not want to cooperate – they’re hard and they weather into resistant and recessive beds which make them very challenging to drill. So the team made the difficult decision to get back on the road, without a drill sample from this location

India’s Chandrayaan-3 lunar lander/rover passes radiation testing

8:59 am


Click for interactive map.

According to India’s space agency ISRO, its next lunar lander/rover, Chandrayaan-3, has successfully passed testing to make sure it can function without issues in the harsh electromagnetic environment of space.

Magnetic Interference/ Electro – Magnetic Compatibility) test is conducted for satellite missions to ensure the functionality of the satellite subsystems in the space environment and their compatibility with the expected electromagnetic levels.

The spacecraft, which will carry a rover to the Moon’s south pole regions (the red dot on the map to the right), is tentatively scheduled for launch anywhere from June to the end of ’23, depending on the news story you read.

First orbital tug from the startup Launcher fails shortly after deployment

1:18 pm

The first orbital tug, dubbed Orbiter SN1, of the startup company Launcher failed shortly after deployment from a SpaceX Falcon 9 rocket on January 3, 2023.

The vehicle communicated with a ground station on its first scheduled pass after deployment while on battery power. “We also communicated with the vehicle for the duration of expected battery life,” the company said.

However, the Hawthorne, California-based company said the spacecraft could not get into the proper attitude so that its solar cells could generate power, which it blamed on “an orientation control issue caused by a fault in our GPS antenna system.” That, in turn, kept Orbiter from deploying its satellite payloads.

The tug was carrying payloads from eight customers, four of which were satellites to be deployed while the others would remain on the tug, using it as the base of operations.

The company presently has plans to launch upgraded tugs on two different Falcon 9 launches, in June and October respectively.

Inspection of leaking Progress after undocking detects no obvious damage

1:10 pm

After undocking the Progress freighter from ISS yesterday, Russian astronauts on the station rolled it so that all sides of its service module could be photographed and inspected in the hope of spotting the leak in its coolant system that sprung on February 11th.

No visual damage has been detected at the Progress MS-21 spacecraft after it undocked from the International Space Station. “After the Progress MS-21 cargo spacecraft undocked from the International Space Station’s Poisk mini-research module, footage was made of its exterior surface and no visual damage was detected,” the statement [from Roscosmos] reads.

Initially the Russians postponed its de-orbit as they considered the idea of redocking the freighter to another port on the Russian half of ISS in order to inspect it more closely, but eventually they decided to fore-go that plan and de-orbit it on February 19th, one day later.

In watching the live stream of the undocking and the roll maneuver, I thought I saw a partial reddish-orange stain, similar to the stain around the hole that occurred in the Soyuz capsule in December, but it was mostly hidden behind other equipment and the Russians seemed to not consider this significant.
