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.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

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.

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.

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.

Russian space junk hit Chinese satellite in March

9:16 am

It now appears that the partial breakup of a Chinese military satellite in March 2021 was caused when it collided with a piece of rocket space junk leftover from a 1996 Russian launch.

It appears that the object that hit the satellite was one of eight pieces left over in orbit from that Russian launch that have been tracked over the years, and was somewhere between 4 and 20 inches in size. The result of the collision?

Thirty-seven debris objects spawned by the smashup have been detected to date, and there are likely others that remain untracked, he added.

Despite the damage, Yunhai 1-02 apparently survived the violent encounter, which occurred at an altitude of 485 miles (780 kilometers). Amateur radio trackers have continued to detect signals from the satellite, McDowell said, though it’s unclear if Yunhai 1-02 can still do the job it was built to perform (whatever that may be).

According to the article, this was the first major orbital collision since 2009, though similar collisions are suspected in 2013 and 2015.

Zhurong completes its planned 90-day mission on Mars

8:54 am

China’s state-run press announced today that its Mars rover Zhurong has successfully completed its planned 90-day mission, is operating without issues, and will continue its exploration of the Red Planet.

The rover has traveled 889 meters as of Aug. 15, and its scientific payloads have collected about 10 Gb of raw data. Now the rover runs stably and operates in good condition with sufficient energy. The CNSA added that the rover will continue to move to the boundary zone between the ancient sea and the ancient land in the southern part of Utopia Planitia and will carry out additional tasks.

According to the administration, Zhurong operated with a cycle of seven days during its exploration and detection. Its navigation terrain camera obtained topographic data along the way to support the rover’s path planning and detection target selection.

Zhurong’s subsurface detection radar acquired the data of the layered structure below the Martian surface, which analyzes the shallow surface structure and explores the possible underground water and ice. [emphasis mine]

This announcement reveals two tantalizing details. First, they are extending the mission, and plan to continue traveling to the south, with a very long term fantasy goal of reaching the transition zone between the northern lowland plains that Zhurong landed in and the southern cratered highlands. That fantasy goal is about 250 miles away. At the pace Zhurong is traveling, about 1,000 feet per month, it will take about a 100 years to cover that ground. Even so, as they move south they are slowly going up hill, and have the chance of seeing some change in the geology along the way.

The second tantalizing detail is indicated by the highlighted last sentence, and is probably the most important data obtained by Zhurong. It suggests they obtained good data from the rover’s ground penetrating radar, and it indicated the existence of underground layers. Whether those layers contain ice however is not clear. From the story it appears the data has not yet been analyzed enough to say.

Lacy patterns in the high north of Mars

12:27 pm

lacy patterns in the high north of Mars

Cool image time! The photo to the right, cropped, reduced, and rotated so that north is up, was taken on May 12, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the strange lacy patterns seen routinely in the very high northern latitudes surrounding the Martian north pole.

Located in a region of the vast northern lowland plains dubbed Scandia Tholi, such features are apparently common here. From a 2011 geology paper of the region’s geological history:

We find that Scandia Tholi display concentric ridges, rugged peaks, irregular depressions, and moats that suggest uplift and tilting of layered plains material by diapirs and extrusion, erosion, and deflation of viscous, sedimentary slurries as previously suggested. These appear to be long-lived features that both pre-date and post-date impact craters.

The small circular feature near the bottom of the picture appears to be a mesa, and might be a pedestal crater, so old that the surrounding terrain has worn away and left the hardened-by-impact crater as a butte. To its right is a larger circular mesa with its scarp well eroded into hollows. This might also be a pedestal crater, or not.

The white lacy patterns could be frost, either water ice or dry ice. That the white lace tends to favor the north-facing slopes lends support to this guess. The photo was taken in the early spring, so the thin mantle of carbon dioxide that falls to cover the polar region south to sixty degrees latitude is only beginning to sublimate away.
