A weak avalanche season on Mars?

1:39 pm

The north pole scarp
Click for full image.

Today’s cool image from Mars is cool both for what is visible in the photo and for what is not, the latter of which might turn out to be a discovery of importance.

The photo to the right, cropped and reduced to post here, was taken on June 24, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a section of the edge of Mars’ north polar ice cap, with north at the top.

This scarp is probably more than 2,000 feet high, though that height drops to the south as the upper layers disappear one by one from either long term erosion or sublimation. Those layers represent the visible information in the photo that is cool. They give us tantalizing clues about the geological and climatic history of Mars. Each layer probably represents a climate period when the north icecap was growing because the tilt of the planet’s rotation was even less than the 25 degrees it is now. When that tilt is small, as small as 11 degrees, the poles of Mars are very cold, and water ice migrates from the mid-latitudes to the poles, adding thickness to the icecaps. When the tilt grows, to as much as 55 degrees, the mid-latitudes are colder than the poles, and the water ice migrates back to the mid-latitudes.

What is not visible in this picture, however, might be far more significant.

Today’s blacklisted American: Priest removed by Catholic Church for condemning Democrats who violate actual Catholic teachings

12:17 pm

Catholic Church now opposes its own basic tenets in order to politically help Democrats
The Catholic Church: Down with Catholic teachings!
Up with the leftist Democratic Party!

They’re coming for you next: A Wisconsin priest was removed from his parish by his superiors in the Catholic Church in late May because he has bluntly condemned Democratic Party politicians for their “pro-abortion, pro-gay marriage, and pro-transgender agendas” that violate the church’s foundational teachings.

The priest, James Altman, is most well known for a video homily he posted that stated the following:

“Here’s a memo to clueless baptized Catholics out there: You cannot be Catholic and be a Democrat. Period,” Altman said in the video. “Their party platform absolutely is against everything the Catholic church teaches. So just quit pretending that you’re Catholic and vote Democrat. Repent of your support of that party and its platform, or face the fires of hell.”

Altman’s homily also strongly criticized his own superiors for their willingness to protect these same Democrats, no matter what those Democrats do.

The knives aimed at SpaceX are getting sharpened

10:01 am

Starship must be banned!
Banning Starship: The new goal of our leftist masters.

Two stories today mark what appears to be a growing political campaign focused on squelching by any means possible the continued unparalleled success of the company SpaceX. And the simultaneous publication of both stories on the same day also suggests that this campaign is deliberately timed to force the FAA to shut down SpaceX at Boca Chica.

First we have a story at Space.com aimed at SpaceX’s Starlink constellation, making it the big villain in the growing threat of satellite collisions.

SpaceX’s Starlink satellites alone are involved in about 1,600 close encounters between two spacecraft every week, that’s about 50 % of all such incidents, according to Hugh Lewis, the head of the Astronautics Research Group at the University of Southampton, U.K. These encounters include situations when two spacecraft pass within a distance of 0.6 miles (1 kilometer) from each other.

Lewis, Europe’s leading expert on space debris, makes regular estimates of the situation in orbit based on data from the Socrates (Satellite Orbital Conjunction Reports Assessing Threatening Encounters in Space ) database. This tool, managed by Celestrack, provides information about satellite orbits and models their trajectories into the future to assess collision risk.

Though his data appears accurate and the growing risk of collisions is real, it appears from the story that Lewis, one of only two experts interviewed, has a strong hostility to SpaceX. He doesn’t like the fact that SpaceX is so successful in such a short time, and appears to want something done to control it.

The article also nonchalantly sloughs off one very significant fact: Very few satellite collisions have actually occurred. While the risk is certainly going to increase, that increase is not going to be fueled just by SpaceX. At least four large constellations are presently in the works, all comparable to Starlink in some manner. To focus on SpaceX in particular makes this article appear like a hatchet job.

Then we have a news story from CBS and its very partisan and leftist news show, Sixty Minutes+, providing a loud soapbox for the very small number of anti-development environmentalists fighting to block SpaceX’s operations in Boca Chica, Texas.

Firefly hires noted SpaceX engineer

9:03 am

Capitalism in space: Firefly Aerospace announced earlier this week that it has hired as it chief operating officer Lauren Lyons, a former SpaceX engineer familiar to many for her regular appearances as a announcer on SpaceX’s launch telecasts.

The company said that Lyons will focus on “transitioning Firefly from an R&D environment to a production environment” for its Alpha small launch vehicle, Space Utility Vehicle tug and Blue Ghost lunar lander. “Firefly is entering a pivotal and exciting phase of its growth,” Lyons said in the statement. “I’m thrilled to take on the challenge of leading the efforts in scaling the company’s infrastructure to support rapid growth, high execution rate, and deliver exceptional value and service to our customers.”

Translation: Using Lyons expertise from SpaceX, Firefly intends to operate much like SpaceX, upgrading its rockets and spacecraft continuously even as they operate commercially.

The launch date for the company’s first orbital attempt remains unannounced, though it says it will occur before the end of the year. It appears they are ready to go, except for one component of their flight termination system.

China launches two more military surveillance satellites

8:52 am

China today used its Long March 4B rocket to put two more military surveillance satellites into orbit.

No word on whether the spent first stage landed near habitable areas in China. China also said nothing about whether that stage carried grid fins or parachutes for bringing it back to Earth more precisely.

The leaders in the 2021 launch race:

27 China
20 SpaceX
12 Russia
4 Northrop Grumman

Russia plans a launch later today (tomorrow in Russia) of another 34 OneWeb satellites. In the national rankings, the U.S. still leads China 31 to 27.

Arizona’s governor moves to block any local school mask mandates or closures

3:39 pm

Doug Ducey, the less than useless Republican governor in Arizona during this past year of Wuhan panic, has apparently finally seen the light, and has begun to take action to prevent the Democratically-controlled local school boards and city governments from imposing new mask and vaccine mandates as well as shutting schools out of an unjustified fear of COVID-19.

Arizona Gov. Doug Ducey on Tuesday announced schools that impose mask mandates in the state will not have access to a $163 million grant program backed by coronavirus relief funds he controls.

The Republican governor said schools with mask mandates or that have closed due to COVID-19 concerns will not be eligible for an additional $1,800 per student. The announcement comes one day after he issued an executive order banning cities and counties from mandating vaccinations.

Ducey also announced a grant program to award parents if their schools require quarantining or isolation of students.

The governor also announced a $10 million grant that intends to award parents $7,000 for each student if their public school required isolating or quarantining due to COVID-19 exposure or if it gave preferential treatment to vaccinated children or mandated masks.

As expected, the Democrats in the state legislature railed against such measures, not because the mandates actually prevent the spread of any disease, but because Ducey’s actions rob them and their allies in local government of the unbridled power they have enjoyed for the eighteen or so months. Before they simply had power, and it corrupted them somewhat. Since the arrival of the Wuhan panic they have had absolute power, and it corrupted them absolutely. They are addicted to it, and can’t tolerate giving it up.

Meanwhile, it should not take a governor to recognize the right of the people to live their lives as they choose. That Ducey has to do this tells us that the public has ceded to much power to the government, no matter who is in charge. That too has to change, and it has to change at all levels, from the smallest local school board to the presidency of the entire nation.

Revolt in San Diego over Democrat-imposed mask and vaccine mandates?

3:27 pm

At a board of supervisors public meeting in San Diego yesterday it appeared that a major revolt is rising against the local government’s demand that businesses impose mask and vaccine mandates on their employees and customers.

Hundreds of businesses have already signed a Business Equality Pledge and posted a Proclamation pledging not to discriminate. Citizens are also signing a petition to refuse to comply with these arbitrary and unconstitutional requirements. The rally attendees are not anti-vax, but they are simply against all medical mandates.

The community members and leaders were fired up, and to put it simply, directly called out the San Diego County Board of Supervisors for their overreaching rule, telling them to their face they have forgotten their oath to protect the constitution.

The article includes almost two dozen videos of statements by various citizens and business owners, telling the supervisors to their face, and by name, that they face a quick recall if they don’t back off and instead try to impose these mandates. These are definitely worth watching, as they indicate the rising anger and frustration many Americans are feeling over the mindless and very damaging and totalitarian government actions over the past year and a half.

The videos and the crowd responses suggest that the public in this southern California town at least has finally turned against their government leadership, which presently has a Democratic Party majority. If so, it will be a welcome and long overdue development.

At the same time, based on past experience one should not get too confident. Many past such protests were not matched by the voters. Moreover, this is California, where the election process has been badly corrupted and is very unreliable. Even if the voters vote to throw these bums out, the bums might very well have the power to revise that result to their favor.

I will not breathe easy and feel real hope until I see some actual electoral changes, at that ballot box, something that has not really occurred since World War II. Even when the voters threw the bums out of Congress in 1994 and 2010, nothing really changed.

And at the local level the public has been less than uninterested in who wins elections. This more than anything has got to change to actually change the government we live under.

A dry bedrock Martian crater floor?

1:01 pm

A dry bedrock crater floor?
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on June 21, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The location is a very eroded crater at about 26 degrees north latitude. The image shows the crater’s crater floor, with a variety of bedrock-type features, sharp ridges, abrupt scarps, and flat smooth plateaus, with a hint of lobate glacial flows in the image’s southeast quadrant.

At 26 north latitude, it is unlikely that anything here is icy, unless it is very well protected by debris. Most of these features are almost certainly bedrock, though their formation could very well have been shaped by ice in past eons when this location was more amenable to water ice.

The wider MRO context camera image of the entire crater, plus the overview map, give a larger picture, and raise some interesting questions.

Today’s blacklisted American: Professor fired by university for having opinions

11:25 am

Today's modern witch hunt
Burn witches: What St. Joseph’s University is doing,
with great enthusiasm.

Today’s blacklist story is an update from a March 25 story. Then, St. Joseph’s University in Pennsylvania had merely suspended Professor Gregory Manco because he dared to publicly express opposition to the idea of paying reparations to blacks for something (slavery) that hasn’t existed in the U.S. for more than 150 years.

The university has now doubled down on that action by terminating Manco’s employment.

The biggest irony is that the school’s own investigation found that Manco had done nothing wrong.

Curiosity produces new 360 degree hi-res panorama

9:50 am

360 degree hi-res panorama from Curiosity
Click for full resolution image.

The Curiosity science team has used the rover’s high resolution camera to produce a new 360 degree panorama, with the center of the image looking directly up at Navarro Mountain.

To get a really good idea of what this panorama shows, I have embedded below a video the scientists have produced giving a tour of the image, which reveals two especially interesting details. First, their future route will go between Navarro Mountain (the highest visible peak) and the 80-foot-high dark butte to its right. This is as planned, as indicated by the red dotted line on the overview map show in this July 8, 2021 post.

Second, the air was very clear when this panorama was taken, and so the rim of Gale Crater can be distinctly seen, 20 miles away.
