Today’s blacklisted American: What the last six months has revealed
Reporting daily the modern witch hunt against freedom and
independent thought.
It is just about six months since I decided to do a daily column entitled “Today’s Blacklisted American.” In that time I have documented more than 120 examples where one group of Americans thought it okay and proper to destroy the livelihood and freedom of other Americans, all because the latter said something the former did not like.
The link will take you to the full list of columns since mid-January. After six months I think it is time to assess what these columns have revealed. And that revelation is quite ugly.

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
Veritasium – Newton reinvents how to calculate pi
An evening pause: Much of the math goes over my head, but the story is still fascinating in showing how you can discover what later seems obvious, merely by keeping an open mind while endlessly and repetitively asking the next question.

Sublimating scallops on Mars
Click for full image.
Today’s cool image, shown in a rotated, cropped, and reduced version to the right, gives us a close-up look at one of the giant scallops found in the high mid-latitudes of the northern lowland plains of Mars, specifically in Utopia Basin north of the landing sites of both Perseverance and Zhurong. In fact, this particular image is only a few miles north of one of my previous cool images, Giant scallops on Mars, posted in December 2019.
The image was taken on February 3, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). While such scallops are not unusual in the mid-latitudes, their formation process is not well understood. As I noted in the 2019 post, ” scientists believe [pdf] the formation process is related to the sublimation of underground ice.”
According to [one hypothesis] scallop formation should be ongoing at the present time. Sublimation of interstitial ice could induce a collapse of material, initially as a small pit, then growing [away from the equator] because of greater solar heating on [that] side. Nearby scallops would coalesce together as can be seen to have occurred.
This hypothesis is not proven, and today’s cool image raises questions about it. Though the bright material at its center suggests exposed ice, supporting the idea that sublimation of ice near the surface created the scallop, the scallop scarps seem more extended and distinct to the south, not the north as this hypothesis proposes. Sunlight should hit the northern scarps more, which suggests they should retreat more instead of the southern scarp.
The overview map below provides the context.

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: Baseball bans man for expressing his opinion at baseball games with banner
Doesn’t exist at the professional baseball games.
This seems especially appropriate during the July 4th weekend: Major League Baseball (MLB) — joining Disney, Sea World, and Sesame Street — has officially banned Dion Cini from all baseball stadiums, simply because he routinely came to games and displayed a “Trump Won Save America” banner.
Cini’s Twitter profile describes him as “Guerilla Marketeer, Political Consultant, Founder of OperationFlagDrop & ‘Professional Provocateur.’”
He has skated with his flag on Wollman Ice Rink, where he was physically assaulted, even though the Trump organization operated Wollman Rink. Cini also unfurled what is rumored to be the world’s largest Trump flag on the front of Trump Tower in Manhattan in March of this year. Cini even dropped a “Trump Pride” flag one day after the end of Pride Month.
Cini has now been banned by MLB stadiums and Disney parks, Sea World, and Sesame Street. As per his Twitter account, he has no plans of stopping the flag drops.
First images from Ingenuity’s 9th flight today
Ingenuity has apparently completed its 9th flight on Mars, its most challenging yet attempted. Based on the six images so far released from that flight, all taking during its landing, it appears the flight was successful. Or at least, the helicopter landed without incident or damage.
The photo to the right was the last picture taken just before touch down. From the caption:
NASA’s Ingenuity Mars Helicopter acquired this image using its navigation camera. This camera is mounted in the helicopter’s fuselage and pointed directly downward to track the ground during flight.
The dark shadow of the helicopter is clearly visible. If you want to see the entire sequence of six images, go to the Ingenuity raw image website and pick the “latest images” filter in the right column. At present it shows this sequence, though I am certain as the day passes images from the entire flight will start appearing.
As noted at the first link above, the flight was to be more than twice as long as any previous flight while flying over the roughest terrain. There was the real risk that its software would become confused by that terrain.

Sun unleashes strongest solar flare since last solar maximum
On July 3, 2021 the Sun emitted the first X-class solar flare of the rising present solar maximum, the first such flare since September 2017 during the previous maximum.
This flare is classified as an X1.5-class flare. X-class denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.
The image to the right was taken by the orbiting Solar Dynamics Observatory (SDO), designed to monitor the Sun continuously and catch such events.
More information here. The flare caused some disturbances to various radio instruments, though nothing that resulted in any serious consequences.
What the flare did demonstrate is that the Sun is definitely ramping up to solar maximum. In fact, the Sun has not been blank, with no sunspots on its facing hemisphere, since May 6th, the longest such stretch since the last solar maximum.
China launches weather satellite
China yesterday successfully launched a new weather satellite using its Long March 4C rocket.
Launched from one of China’s three interior spaceports, the first stage crashed somewhere within China. No word on whether it came down near inhabited areas.
The leaders in the 2021 launch race:
20 SpaceX
20 China
11 Russia
3 Northrop Grumman
The U.S. still leads China 29 to 20 in the national rankings.
Sunspot update: The hot streak continues
This past weekend NOAA released its monthly update of its graph showing the Sun’s sunspot activity, with the new update covering the period through the end of June 2021. As I have done since I began this website eleven years ago, I post that monthly graph below, annotated to show the previous solar cycle predictions and thus provide context.
In June the hot streak of sunspot activity exceeding the prediction of NOAA’s solar science panel continued, with activity rising again after a tiny dip in May. Except for two months, since 2019 the number of sunspots each month has consistently exceeded the prediction. Furthermore, the ramp up of activity has been faster than expected.

Next Ingenuity flight to push envelope significantly
Click for full image.
The engineers running the Mars helicopter Ingenuity revealed today that they will be attempting their most ambitious flight for the helicopter’s ninth flight, presently scheduled for no earlier than July 4th.
I have annotated the map to the right to show Ingenuity’s present position and its approximate landing area.
Without question this flight will be the riskiest taken by Ingenuity so far, more than doubling the flight distance achieved on any previous flight. More important, it will be flying over terrain far rougher than it was initially designed for.

More parachute problems for Europe’s Franklin Mars rover
During a parachute drop test in late June, following a redesign of the parachute with U.S. help, engineers for the ExoMars Rosalind Franklin Mars rover found the chute still experienced problems that tore it during deployment.
They actually performed two drop tests, a day apart, using two different parachutes, with the first test apparently going off without a hitch. However, according to the press release:
“The performance of the second main parachute was not perfect but much improved thanks to the adjustments made to the bag and canopy. After a smooth extraction from the bag, we experienced an unexpected detachment of the pilot chute during final inflation. This likely means that the main parachute canopy suffered extra pressure in certain parts. This created a tear that was contained by a Kevlar reinforcement ring. Despite that, it fulfilled its expected deceleration and the descent module was recovered in good state.”
I have embedded below the fold the only video released by the European Space Agency. It is not clear whether this is from the first or second test. Near the end it appears that the pilot chute above the main chute might be separated, but the video ends before that can be confirmed.
Though ESA has apparently improved the chute’s performance significantly since its earlier failures that contributed to the delay of ExoMars from last year to 2022, they still haven’t gotten the chute completely right. Fortunately they still have time to get it fixed before that ’22 launch.
