Pushback: Blacklisted doctors join lawsuit against Biden administration COVID censorship

2:16 pm

Correct from the start despite government censorship
Correct from the start despite government censorship

Bring a gun to a knife fight: Three well-known research doctors have now added their names to a lawsuit filed by two states that accuses the Biden administration of coordinating with major social media companies like Google and Twitter to censor all posts critical of administration COVID policies.

Drs. Jayanta (Jay) Bhattacharya, Martin Kulldorff and Aaron Kheriaty joined the lawsuit filed by the states of Missouri and Louisiana, alleging that the Centers for Disease Control and Prevention (CDC) and Department of Homeland Security (DHS) worked with Big Tech companies to censor Americans discussing the pandemic. The doctors alleged they were censored on social media platforms for expressing views in opposition to the positions of the federal government, their representation, the New Civil Liberties Alliance (NCLA), said in a Tuesday press release.

Kheriaty was blackballed by his hospital and banned from seeing patients back in October ’21 because after looking the data he had decided to recommend his patients not get the jab.

Kulldorff, one of the world’s foremost experts on vaccines, was blacklisted from Twitter, Linkedin and the CDC in August ’21, also because he challenged the government mandates that required people to get the COVID shots.

Kulldorff and Bhattacharya were co-authors of the Great Barrington Declaration, which condemned the lockdowns and mandates and instead called for a more traditional focused policy for dealing with the Wuhan flu:

Curiosity finally looks out into Gediz Vallis

12:56 pm

First look into Gediz Vallis

Overview map
Click for interactive map.

Cool image time! Curiosity’s right navigation camera today produced the mosaic above, cropped and reduced to post here, taking its first good look into Gediz Vallis, the canyon that the rover has been aiming for since it landed on Mars ten years ago.

The green dot on the overview map to the right marks the approximate location of a recurring slope lineae, a streak that comes and goes depending on the seasons whose cause remains uncertain. The yellow lines show the approximate area covered by the mosaic. The red dotted lines show Curiosity’s upcoming route. According to previously announced plans, the rover will not head straight into Gediz Vallis, but circle to the west or right of the mesa to the right of Kukenan.

The valley of course looks spectacular. For scale, the cliff face of Kukenan is estimated to be about 1,500 feet high.

The most important revelation from this image however is the ground terrain. It looks like Curiosity will have no problem moving forward into the canyon from this point, something the science team could not know for sure until the rover reached the saddle and could look down and actually see ahead.

InSight seismometer data suggests no underground ice at landing site

9:25 am

Using a computer model combined with seismometer data gathered by the Mars lander InSight, scientists have concluded that there is little or no underground ice in the equatorial region where InSight sits.

From the paper’s abstract:

We use rock physics models to infer cement properties from seismic velocities. Model results confirm that the upper 300 m of Mars beneath InSight is most likely composed of sediments and fractured basalts. Grains within sediment layers are unlikely to be cemented by ice or other mineral cements. Hence, any existing cements are nodular or formed away from grain contacts. Fractures within the basalt layers could be filled with gas, 2% mineral cement and 98% gas, and no more than 20% ice. Thus, no ice- or liquid water-saturated layers likely exist within the upper 300 m beneath InSight. Any past cement at grain contacts has likely been broken by impacts or marsquakes.

As the lander sits just north of the equator in the red planet’s equatorial zone, which ample orbital data has suggested is a dry region (as shown in the global map below), this result is not a surprise. It does provide further confirmation however of this conclusion, that if there is any water on Mars within 30 degrees latitude of the equator, it will be deep underground, and likely only in certain regions.

Another and this time longer static fire tests for Superheavy prototype #7

9:02 am

Capitalism in space: SpaceX engineers yesterday conducted a second static fire engine test of the 7th prototype of its Superheavy first stage booster, firing a different engine for 20 seconds.

The action ramped up on Thursday (Aug. 11) for Booster 7, which conducted a much longer static fire on Starbase’s orbital launch mount. The burn, which occurred at 3:48 p.m. EDT (1948 GMT), lasted for 20 seconds, SpaceX said via Twitter (opens in new tab).

The long-duration burn aimed to “test autogenous pressurization,” according to a tweet posted by Musk (opens in new tab) shortly before Booster 7 fired up.

Expect these engine tests to occur on a regular basis over the next few weeks, as engineers ramp up their operations in preparation for the first orbital flight of both prototype #7 with Starship prototype #24 stacked on top.

A union official’s opinion of blacklisting: “I am all about targeted assassinations.”

11:50 am

Southwest Airlines: Enemy to free speech

Today’s blacklisting story is a further update in connection with the victory by former Southwest Airline flight attendant Charlene Carter, who was fired by the airline for having opinions neither the airline nor her union liked.

Carter sued, and was awarded by a jury $4.15 million from Southwest and $950,000 from Local 556 of the Transport Workers Union (TWU) for what the jury deemed an unjust firing.

As I noted at the link,

Carter had sent blunt Facebook messages to Audrey Stone, the head of the union, criticizing its pro-abortion stance and its apparent use of union funds to send flight attendants to a 2017 pro-abortion protest in Washington, D.C. Southwest decided expressing such opinions was unacceptable and fired her. The union agreed, doing nothing to support her as it is supposed to do.

Both Southwest and the union are appealing this jury decision, and that’s where this update comes in. A Texas news outlet has apparently obtained copies of emails used as evidence during the trial that were sent by TWU official Brian Talburt to one Southwest manager as well as his boss, union head Audrey Stone, discussing the actions the union and Southwest should take together against several non-union Southwest employees.

A typical Martian rock on Mount Sharp

Typical Martian rock
Click for full image.

Cool image time! The photo to right, taken by the Mars rover Curiosity on August 9, 2022, provides a nice close-up of what might be a somewhat typical rock on the flanks of Mount Sharp in Gale Crater, many layered with some of those layers extending outward to the side for somewhat ridiculous distances as thin flakes.

The scientists call it a float rock, because they think it actually fell from the cliff dubbed Bolivar in the panorama above. Thus, it gives geologists data on the layers higher up that are not easily accessible from Curiosity’s present position.

The panorama is a mosaic created from images taken by the rover’s right navigation camera on August 8, 2022. The white arrow marks the rock. The green dot marks the approximate location on the cliff face of a previously observed recurring slope lineae, streaks that appear to come and go seasonally whose origin is still not understood.

The red dots mark my guess as to the route engineers will pick for Curiosity as it weaves its way around the other float rocks ahead.

SpaceX gets FCC communications license for Starship orbital launch

8:47 am

Capitalism in space: The FCC yesterday approved SpaceX’s communications license for one or more Starship orbital launches, with a six month launch window beginning on September 1, 2022.

This FCC approval is not a launch license, which must be given by the FAA. It does tell us that SpaceX will not attempt the first orbital launch of Starship before the end of this month. It also tells us that the company likely plans on an aggressive test program from September ’22 through February ’23, assuming the FAA and the federal bureaucracy finally stops blocking that program.

FCC cancels $900 million award to Starlink

3:07 pm

The FCC today canceled a $900 million subsidy it had awarded to SpaceX in December 2020 as part of a federal program to help establish broadband service in rural communities.

The reasoning for canceling the award given at the link is very unclear. However, since the award a lobbying effort by Starlink’s competitors — teamed up with Democrats in Congress — to cancel the award has been on going. It now seems to have succeeded.

Another clue to explaining this cancellation is timing. The award was announced at the end of the Trump administration, when his appointees controlled the FCC. The cancellation took place during the Biden administration, with the FCC now controlled by Democrats who are increasing revealing themselves to be very hostile to private commercial space in general and Musk and SpaceX in particular.

Nonetheless, it seems absurd to give SpaceX any such subsidy, regardless of the politics. As I said in February 2021:

No one, including SpaceX, should get these funds. SpaceX is proving they aren’t necessary to get the job done (bringing fast internet service to rural communities). Moreover, the federal government really doesn’t have the cash, deep in debt as it is.

Sadly, just because the FCC cancelled its award to SpaceX we should not expect as modern taxpayers that the money won’t be spent. Expect the Biden administration to instead dole it out to its preferred vendors.

Fractures in the Martian northern lowland plains

Fractures in the northern lowland plains
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on April 21, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) of a spot in the Martian northern lowland plains.

Generally the surface of these lowland plains — especially at high latitudes above 30 degrees — tends to appear very water saturated, producing blobby features and what look like mud volcanoes. This picture however features something different, what the scientists have labeled fractures, geological features that appeared caused by dry conditions and sudden quake-like events. The break in the fracture near the top of the photo illustrates why water flow had little if anything to do with its formation. Other fractures in the full image show the same thing. Also the stippled surface along the picture’s right edge also suggest there is little near surface water or ice at this location.

The location, as shown by the overview map below, suggests that water might still have played a part, but only a long time ago.
