A peanut-shaped crater in the northern plains of Mars
Click for full image.
Cool image time! The photo to the right, rotated, cropped and reduced to post here, was taken in May 2008 by the wide angle context camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists have since labeled a “peanut-shaped crater.”
What caused this unusual shape? The obvious and most likely explanation is that this was a double impact that occurred simultaneously. Imagine the ground being hit either by an asteroid with two lobes or by two similar-sized asteroids falling side-by-side.
Fast forward thirteen years to 2021. In the fifteen years since 2006 when MRO begin science operations in orbit around Mars no high resolution images were taken of this crater. Finally, on July 30, 2021, scientists finally decided to take a high resolution image of this crater’s western half. You can see that image below, rotated, cropped, and reduced to post here.

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
Today’s blacklisted American: Lyft driver fired because his radio was tuned to a black conservative
No freedom of speech allowed at Lyft!
The new dark age of silencing: A driver has been fired by Lyft because a passenger complained that he was listening to a racist on the radio, when in fact his radio was tuned to a black conservative.
Ryan Alexander, who had been a Lyft driver for years, tells “The Dan O’Donnell Show” that a Lyft representative told him during a phone call Saturday that his account was suspended because he had been listening to “racist talk radio programming,” a violation of the app’s terms of service.
Alexander says he was listening to former Milwaukee County Sheriff David Clarke fill in for Mark Belling during the “Mark Belling Late Afternoon Show” Thursday evening when a passenger took exception to the discussion Clarke was having about Black Lives Matter and abortion rates in the African-American community.
“She called Clarke trash, slammed the door to my car when she got out, and specifically referenced abortion which Clarke did talk about briefly while she was in the car,” Alexander says.
During the portion of the program that the passenger heard, Clarke, who is Black, expressed the opinion that the Black Lives Matter organization did not truly care about Black lives because it was not upset about the rate of abortions among Black mothers.
The troubled politics of ground-based astronomy
Link here. The article outlines the politics and negotiations now going on during the writing of the next astronomy decadal survey, the document American astronomers have published every decade since the 1960s to provide the science agencies in the federal government guidance on how to spend the taxpayers’ money on the next decade’s astronomy projects.
The focus is on the problems now faced by the two big American ground-based telescopes, the Thirty Meter Telescope (TMT) and the Giant Magellan Telescope (GMT).
The future of the Giant Magellan Telescope (GMT) and the Thirty Meter Telescope (TMT) likely depends on whether the survey recommends that NSF spend what sources put at $1.8 billion to support a recently forged partnership between the projects. If it does, other proposals could lose out, such as a continent-spanning radio array and detectors for neutrinos and other cosmic particles.
While some astronomers are pushing for this $1.8 billion bailout to save both, others are arguing the money can be better spent elsewhere. There is also a third option, not mentioned, which would be to abandon one of these telescopes and instead build just one.
The story is focused entirely on ground-based astronomy, which is remarkably very near-sighted for scientists whose job it is to see a far as possible. The future of astronomy is in space, and to not consider that alternative in this discussion means you aren’t considering all your options. For $1.8 billion, using private rockets and competitive construction approaches, I strongly believe a very large optical telescope could be launched that would provide far more cutting edge astronomy than any larger ground-based telescope. Hubble has proven that endlessly for the past thirty years.
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.

Prototype of reusable suborbital spaceplane from new startup completes five flights
Capitalism in space: Another rocket startup company, Dawn Aerospace, has completed a five flight test program of a prototype of its proposed reusable suborbital spaceplane, dubbed Aurora.
Dawn Aerospace has successfully completed five test flights of its uncrewed Mk-II Aurora suborbital spaceplane in the skies over Glentanner Aerodrome on New Zealand’s South Island. The flights were conducted by the New Zealand-Dutch space transportation company from July 28 to 30, 2021 at altitudes of up to 3,400 feet (1,036 m), with the prototype airframe fitted with surrogate jet engines.
The three-days of test flights to assess the airframe and avionics of the aircraft took place under a certificate issued to Dawn by the New Zealand Civil Aviation Authority (CAA), which allowed the Mk-II Aurora to operate from conventional airports without airspace restrictions after ground tests were completed.
The company claims this is a demonstrator for their fullscale two-stage-to orbit version that will take off from a runway and then launch small satellites into orbit.
Looks impressive, but my impression of this prototype is that it is a small scale model, only slightly more sophisticated and larger than a model airplane. That impression is reinforced by the video at the link, which provides no visible markers to judge size.
This company needs to get a lot more done if it wants to compete in this new market.
Firefly set for first orbital launch today
Capitalism in space: If all goes right, Firefly Aerospace will attempt its first orbital launch today from Vandenberg Space Force Base in California, using its Alpha rocket to place a test payload of science experiments in space.
The launch window is from 6 pm to 10 pm Pacific.
If you wish to watch, I have embedded the live stream below. That stream however have been very poor. The stream is working better here.
Note: They had a launch abort right at launch, and appear to be recycling to try again.

China building Ingenuity copycat
China’s space program revealed yesterday that it is designing its own Mars helicopter for future missions to the Red Planet.
The picture to the right shows this Chinese helicopter prototype on the bottom, with Ingenuity on Mars on top.
Notice the similarity? In fact, one could almost say that the Chinese helicopter is an outright steal of the JPL design.
But then, why not? According to an 2019 inspector general report [pdf], China hacked into JPL’s computers twice from 2009 to 2017 and stole 500MB of data. That data almost certainly included the design plans for Ingenuity, under development at the time.
Copying the work of others is expected, especially when that design is found to work. In this case however it almost certainly isn’t copying, but outright theft.
Of course, that has been par for the course for China’s space program. They don’t appear to be capable of innovating on their own. They first must steal someone else’s design, and then revise and upgrade from that. Their final products might be of high quality, but in the end their long term ability to build something new is going to be severely limited, if they cannot start inventing things on their own.
Flight anomalies occurred during Branson’s suborbital flight in July
Capitalism in space: According to a New Yorker story today, the suborbital flight of Richard Branson in July experienced several flight anomalies that the article suggests should have caused it to end early before reaching space.
The rocket motor on Virgin Galactic’s ship is programmed to burn for a minute. On July 11th, it had a few more seconds to go when a red light also appeared on the console: an entry glide-cone warning. This was a big deal. I once sat in on a meeting, in 2015, during which the pilots on the July 11th mission—Dave Mackay, a former Virgin Atlantic pilot and veteran of the U.K.’s Royal Air Force, and Mike Masucci, a retired Air Force pilot—and others discussed procedures for responding to an entry glide-cone warning. C. J. Sturckow, a former marine and nasa astronaut, said that a yellow light should “scare the [“#$%#] out of you,” because “when it turns red it’s gonna be too late”; Masucci was less concerned about the yellow light but said, “Red should scare the crap out of you.” Based on pilot procedures, Mackay and Masucci had basically two options: implement immediate corrective action, or abort the rocket motor. According to multiple sources in the company, the safest way to respond to the warning would have been to abort. (A Virgin Galactic spokesperson disputed this contention.)
Aborting at that moment, however, would have dashed Branson’s hopes of beating his rival Bezos, whose flight was scheduled for later in the month, into space. Mackay and Masucci did not abort.
Virgin Galactic’s response, including the FAA’s statement, can be found here. The company noted that the flight deviation occurred because of unexpected high altitude winds. The FAA’s comment I think provides some reasonably perspective:

Rose Royce – I Wanna Get Next To You
An evening pause: Hat tip Diane Zimmerman.
Today’s blacklisted American: Cancelled by his bank for being pro-life, he started his own
What too many banks want to do to conservatives.
Today’s story is similar to my blacklist story two days ago about former national security advisor Michael Flynn [See the bottom of this post for an update on the Flynn story!]
Just as Flynn was blackballed by Chase bank, evangelist and motivational speaker Nick Vujicic found himself frozen out by his own bank because of his Christian, political, and pro-life beliefs.
Vujicic said he began to speak out against the innocent killing of unborn babies in March 2019. Within 16 weeks of doing that, he revealed, “we had a grenade at our house, a false magazine article published against me, a lawsuit threat, a spying drone, and a bank kicked me out.”
…”I got kicked out of a bank with no warning. They froze my credit cards, froze my debit cards,” he said. “They gave me a letter to say that they did a review of me as a client and they don’t want anything to do with me.”
What makes this story different from the Flynn story is that Vujicic responded by starting a project to found his own bank.

A Martian sunset in Jezero Crater
Click for full image.
Cool image time! The photo to the right, reduced slightly to post here, was taken by the left navigation camera on the Mars rover Perseverance. Looking west to the rim of Jezero Crater, it catches the Sun as it sets behind that rim.
The image was taken on July 20, 2021, the 52nd anniversary of the Apollo 11 landing on the Moon. Seems somehow fitting to catch a sunset on Mars on this date, to illustrate how far we have come in that half century.
To my mind, not enough. Our ability to send robots to other worlds has certainly improved, but in 1969 we were able to put a human on another world. Since 1972 we no longer have had that capability, so that in 2021 all we can do is fly robots elsewhere.
It is time for this to change. I’d much prefer to make believe this photo was a sunrise suggesting a bright future, than the sunset it actually is, indicating a coming dark age.
