Pushback: Gestapo police chief who raided Kansas newspaper in August suspended

They’re coming for you next: For his part of a Gestapo-like raid in August of the town’s newspaper, the police chief of the town of Marion in Kansas, Gideon Cody, was suspended from his job on September 30, 2023 by the town’s mayor, Dave Mayfield.

Cody’s suspension is a reversal for the mayor, who previously said he would wait for results from a state police investigation before taking action. Vice-Mayor Ruth Herbel, whose home was also raided Aug. 11, praised Cody’s suspension as “the best thing that can happen to Marion right now” as the central Kansas town of about 1,900 people struggles to move forward under the national spotlight.

At the moment is not clear whether Cody’s suspension is with or without pay.

This is a followup on a previous blacklist column, posted in August when that raid occurred. The raid, which not only included the newspaper’s offices but the homes the town’s vice mayor, the newspaper’s 98-year-old owner, Joan Meyer (resulting in her death the next day from a heart attack), and one reporter.

As noted then, the raid was uncalled for on numerous levels. » Read more

Layered ice sheets on Mars?

11:15 am

Overview map

Layered ices sheets on Mars?

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The white spot near the center of the overview map above marks its location, deep inside the 2,000-mile-long region in the northern mid-latitudes I call glacier country, as everything there seems covered with glacial features of some kind. All the features in this picture are smaller than 50 feet high, based on the resolution of the topographical data obtained by Mars Global Surveyor in the 1990s.

What makes this picture interesting are the layers, made most obvious in the terraced mesa in the upper left. Surrounding this mesa for dozens of miles in all directions are similar layered features, all suggesting that the glacial ice sheets that appear to coat this region have either have been sublimating away over time, or when growing grew less with each subsequent growth cycle.

Though both have or are likely happening, the latter most likely explains the terraces, as there is a lot of evidence on the surface of Mars showing that each subsequent growth cycle produced smaller glaciers and ice layers.

From the perspective of future colonists, this picture once again shows that water will readily accessible on Mars, as long as you travel north or south of the equator at least 30 degrees of latitude. This location is at 42 degrees north, and is very typical of this whole region.

Perseverance spots a Martian dust devil

9:15 am

Panorama showing dust devil
Click for movie.

During their normal use of Perseverance’s navigation cameras to survey upcoming terrain for future travel, the rover’s science team captured a short movie of a Martian dust devil as moved across a nearby ridgeline. I have annotated a still from that move above to indicate the dust devil.

The lower portion of a Martian dust devil was captured by one of the Navcams on NASA’s Perseverance rover on Aug. 30, 2023, the 899th Martian day, or sol, of the mission. The video, which has been enhanced in order to show maximal detail, was sped up 20 times and composed of 21 frames taken four seconds apart.

Using data from the imagery, mission scientists determined that the dust devil was about 2.5 miles (4 kilometers) away, at a location nicknamed “Thorofare Ridge,” and moving east to west at a clip of about 12 mph (19 kph). They calculated its width to be about 200 feet (60 meters). While only the bottom 387 feet (118 meters) of the swirling vortex are visible in the camera frame, scientists used the dust devil’s shadow to estimate its full height at about 1.2 miles (2 kilometers).

This Perseverance movie is not the first to catch a dust devil on the surface. Both Curiosity and Perseverance have done so previously, and I think the smaller earlier rovers Opportunity and Spirit did so as well. Nonetheless, this mini-twister provides more information about the atmosphere of Mars.

Stopgap budget bill includes three-month extension of regulatory “learning-period”

9:00 am

The stopgap 45-day continuing resolution passed by Congress on September 30, 2023 also included a three-month extension of regulatory “learning-period” first established in 2004 and extended several times since then.

Among the provisions in that FAA reauthorization was a three-month extension of the existing restrictions on the FAA’s ability to regulate safety for commercial spaceflight participants. That restriction, often called a “learning period” by the industry, was set to expire Oct. 1 but now runs until Jan. 1.

It must be noted that this so-called limitation on FAA regulation of commercial spaceflight really does not exist any longer, no matter what law Congress passes. The administrative state really runs the show now, and both the FAA and Fish & Wildlife have decided heavy regulations are required, and are imposing such controls over SpaceX’s Superheavy/Starshp test program, while the FAA by itself is imposing strict regulation on Blue Origin’s New Shepard suborbital spacecraft. The result is a slowdown in launches for both, extending months to a year.

It also appears that this heavy regulation is squelching launches of new rockets. Last year four new rocket startups attempted new launches (Astra, ABL, Firefly, Relativity), some making multiple attempts. This year, such test flights have essentially ceased, with only Firefly completing one launch for the military. Worse, two of those companies (Astra and Relativity) have abandoned their rockets entirely, claiming they are building new bigger versions, but one must now wonder.

The long term historical significance of these facts extends far beyond the space industry. Increasingly the unelected bureaucracy in Washington is taking on powers it is not supposed to have, while Congress (which is delegated those powers) increasingly is irrelevant. The shift in power signals a major reshaping of American governance, in a direction that is not good for freedom or the fundamental concepts that established the country and made it a success.

SpaceX puts another 22 Starlink satellites into orbit

1:57 pm

SpaceX last night successfully launched another 22 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its tenth flight, landing safely on a drone ship in the Atlantic.

The leaders in the 2023 launch race:

69 SpaceX
44 China
13 Russia
7 Rocket Lab
7 India

American private enterprise now leads China in successful launches 79 to 44, and the entire world combined 79 to 71. SpaceX by itself now trails the rest of the world combined (excluding American companies), 69 to 71.

Note that this was the 151th successful launch in 2023, all done in the first three quarters, and strongly suggesting the world will complete more than 200 launches this year. This number will top the record of 179 set last year by more than ten percent, and be more than double the number of launches achieved almost every year since Sputnik in 1957.

  • China announces a few basic details of its Chang’e-6 sample return mission

    • All they say is it will launch on a Long March 5 rocket in May 2024, head to the South Pole-Aitken Basin on the far side of the Moon, and operate for 53 days (which likely includes the return of the sample to Earth). Jay spotted one mystery however: The coordinates provided (“S43, W154”) are no where near the south pole, though it is likely in the northernmost part of Aitken Basin.

Updated map of Yutu-2’s travels on far side of the Moon

3:01 pm

Map showing Yutu-2 full route on Moon
Click for original image.

The Chinese agency operating the Yutu-2 rover on the far side of the Moon today released an updated map showing the rover’s full route since landing, the first update since January 2023. That map is to the right, reduced to post here. The landing site is in the lower right, with the rover presently in the upper left.

Since January the rover has apparently traveled only about 300 feet, even though it has had about eight lunar days to travel. Note too that the last update was also the first in three months. It appears the Chinese are either having issues with the rover (not surprising as it has been operating on the Moon for almost five years, since January 2019), or they have decided they don’t need to tell anyone what they are doing.

Since the rover was not expected to last more than a few lunar days (several Earth months), the former is more likely.

Today’s blacklisted American: Coach fired by Vermont school for simply expressing some facts during a civil conversation

2:11 pm

Vermont: Where you are only allowed to say things that support the queer agenda
Vermont: Where the only speech allowed must
support the queer agenda

They’re coming for you next: Despite founding the snowboarding program at Woodstock Union High School in Vermont in 2011 and heading it for its entire history, David Bloch was immediately fired without due process by his school the day after he had a very civil private conversation with his students about males claiming to be female and competing against women.

This is what he did, according to his non-profit legal firm, the Alliance Defending Freedom:

In February [2023], Bloch and his team were waiting in the lodge for a competition to start. That day, Bloch’s team was set to compete against a team that had a male snowboarder who identifies as a female and competes against females. During downtime in the lodge, Bloch overheard a conversation between two of his athletes about that male competing against females. Bloch joined the conversation to comment that people express themselves differently and that there can be masculine women and feminine men. He also affirmed that as a matter of biology, males and females have different DNA, which causes males to develop differently from females and have different physical characteristics, and that those biological differences give males an advantage in athletic competitions.

The conversation was respectful among all parties and lasted no more than three minutes. It took place entirely outside the presence of the male snowboarder who identifies as female, and Bloch’s team and the other team went on to compete without incident. After the competition, the two teams and their coaches, including Bloch, shared a bus home.

The very next day the superintendent of the Windsor Central Supervisory Union, Sherry Sousa, called Bloch into her office to tell him he was fired, even though the investigation against him was incomplete.

Is this the source of the sand for the giant dune sea that surrounds the Martian North Pole?

12:49 pm

Overview map

Circling the north pole of Mars is a gigantic dune field dubbed Olympia Undae, with its densest regions (marked in red on the overview map to the right) estimated to be 700 miles long and covering 120 degrees of longitude.

Where does all the sand come from that created this dune ocean? We now have a rough idea. The arrows on the map to the right indicate the direction of the prevailing winds, as recently determined by scientists studying the orientation of dunes. From this it appears that much of the dust comes from the north polar icecap itself, from its lower layers where dust and ice are cemented together. The prevailing winds, especially in the canyons that cut into the icecap, drive that dust out from the lower layers, where it over eons has piled up in that circular ocean of sand.

The white cross marks the location of today’s cool image, an attempt by scientists to photograph at high resolution one of the sources of this sand, on the edge of the icecap.

Hubble data shows expansion of supernova remnant

9:57 am

Cygnus loop filament

Astronomers have created a four-second long movie using Hubble images collected over twenty years that shows the expansion of one filament in the Cygnus Loop supernova remnant, the explosion of which is thought to have occurred 20,000 years ago.

The picture above is one frame of that movie. The filament is estimated to be two light years in length.

By analyzing the shock’s location, astronomers found that the shock hasn’t slowed down at all in the last 20 years, and is speeding into interstellar space at over half a million miles per hour – fast enough to travel from Earth to the Moon in less than half an hour. While this seems incredibly fast, it’s actually on the slow end for the speed of a supernova shock wave.

Two versions of the movie are at the link, with the longer providing excellent context.
