A buried crater on Mars
The overview map to the left indicates the general terrain surrounded today’s cool image. The white rectangle is the area covered by this image, taken on July 4, 2020 by the high resolution camera on Mars Reconnaissance Orbiter. If you look close you can see that this photograph covers the eastern rim of what looks like an ancient and mostly buried crater on Mars. This unnamed crater is about 17 miles across.

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
New data: young red dwarf stars are not nice stars for life
New data from both the Chandra X-ray Observatory and the Hubble Space Telescope has reinforced earlier data that suggested the strong flares emitted by young red dwarf stars make them inhospitable to the development of life on any planet in the habitable zone.
A new study using NASA’s Chandra X-ray Observatory and Hubble Space Telescope examined the red dwarf called Barnard’s Star, which is about 10 billion years old, more than twice the current age of the Sun. Red dwarf stars are much cooler and less massive than the Sun, and are expected to live much longer lives because they do not burn through their fuel as fast. Barnard’s Star is one of the closest stars to Earth at a distance of only 6 light-years.
Young red dwarfs, with ages less than a few billion years, are known as strong sources of high-energy radiation, including blasts of ultraviolet light and X-rays. However, scientists know less about how much damaging radiation red dwarfs give off later in their lifetimes.
The new observations concluded that about 25% of the time, Barnard’s Star unleashes scorching flares, which may damage the atmospheres of planets closely orbiting it. While its only known planet does not have habitable temperatures, this study adds to evidence that red dwarfs may present serious challenges for life on their planets.
It is very important to remember that this data makes difficult the formation of life, as we know it. Since we know so little about such processes, as well as the formation processes of solar systems, it is too early to say whether no life can ever form around such stars.
Scientists confirm another 44 black hole mergers detected by gravitational waves
Scientists have now confirmed that since the first detection of a gravitational wave five years ago they have detected another 44 black hole mergers in the same manner.
A global network of scientists has completed the first major analysis of gravitational wave data, providing exciting insights into some of the most exotic objects in the Universe. “We are announcing the discovery of 44 confirmed black hole mergers, which is a more than a four-fold increase in the number of previously known gravitational-wave signals,” says Shanika Galaudage from Australia’s Monash University, who was part of the research team.
…Their results are described in a trio of papers on the pre-print server arXiv. The first paper describes 39 new detections from the first half of the observing run, primarily of binary black hole systems. This brings the total number of gravitational wave events detected to 47, of which 44 are confidently double black holes, two are confidently double neutron stars, and one is still uncertain.
They think they are detecting more black hole mergers because they are heavier and thus emit bigger and more easily detected waves. They are also finding that the black hole mergers fall into two classes, two holes spinning in the same direction and two holes spinning in opposite or randomly different directions. The former formed together as a binary star system. The latter formed independently and somehow ended up linked up and merging.

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.

U.S. court orders India’s s space agency ISRO to pay $1.2 billion
A U.S. court has ordered Antrix, the commercial arm of India’s space agency ISRO, to pay $1.2 billion to Devas, a private company with operations in both India and the United States, for a contract they canceled arbitrarily in 2011.
This is a very complicated story going back many years. ISRO’s Antrix and Devas had agreements beginning in 2005 to work together to develop commercial satellites, with Antrix building the satellites and Devas commercializing bandwidth. In 2011 the India government cancelled the contracts unilaterally.
On February 25, 2011, Antrix issued a termination notice to Devas, which among other things stated that the policy decision was of the central government, acting in its sovereign capacity is the event of force majeure, which was an occurrence on February 23, 2011, PTI report said. “The scope and duration of the said decision cannot be anticipated. It is likely to be indefinite. It is not possible for Antrix to take any effective step to resume the obligations under the agreement,” Antrix was quoted as saying.
One of the reasons for the cancellation were accusations that payoffs were occurring between officials at both Antrix and Devas to make the deal happen.
Devas has been fighting in numerous courts for years to get compensation for that cancellation.
ISRO can probably ignore this U.S. court decision, except that if it does it will make it very difficult, if not impossible, for ISRO to do any work in partnership with the U.S., such as in the Artemis program. As soon as they try to do so, Devas will slap a lien on that operation, demanding payment.
Russian astronaut: Crack on ISS could be from “external impact”
Russian astronaut, Sergei Ryzhikov, today noted that to him the 1-inch crack causing the leak on ISS appeared to have been caused by an “external impact.”
Speaking with Flight Director of the Russian segment of the ISS Vladimir Solovyov, Russian cosmonaut Sergei Ryzhikov said: “If you take a closer look at the picture, there are changes of color in the middle of the crack.”
“We suspect an external impact,” Ryzhikov said adding that the place of the suspected impact should be examined during the crew’s next spacewalk, which is scheduled for November 18.
This conclusion is different than that expressed yesterday by another Russian astronaut, who suggested the crack was from age and wear and tear of the twenty-year-old Zvezda module.
Either way, an inspection of the exterior point of the crack is essential in order to permanently seal it, and that inspection will tell us one way or the other the cause of the crack.

War between two Spanish space balloon companies
Capitalism in space: A legal battle is developing between two different Spanish high altitude space balloon companies, one that came first, and a second that is being backed by a venture capitalist who had previously worked at the first.
Jose Mariano Lopez Urdiales, an MIT-trained aeronautics engineer who founded Zero 2 Infinity 11 years ago, says Kemel Kharbachi, the now CEO of EOS X Space, worked closely with the company to raise a €1m investment for Zero 2 Infinity. But the funding deal never happened.
Instead, Kharbachi, whose previous experience has focused on tourism and catering, has emerged to build his own rival space balloon business.
It does appear, from the details outlined in the article, that Kharbachi essentially stole the concept and designs from Zero 2 Infinity in order to form his own company.
As these Spanish companies fight it out, a third company in America, Space Perspectives, hopes to begin flying tourists on its stratospheric balloon, dubbed Neptune, by ’24.

ESA maps out first launch schedule for new rockets
Capitalism in space? The European Space Agency (ESA) today laid out the development roadmap that will lead to the launch of two new rockets, the Vega-C being built by the Italian company Avio, and the Ariane 6 being built by ArianeGroup.
The Vega-C is a more powerful version of the Vega rocket, aimed at capturing the smaller satellite market. It maiden flight is now scheduled for June ’21.
The Ariane 6 is aimed at replacing the Ariane 5, Europe’s big workhorse rocket, but to do so at a lower cost. Its maiden flight is now set for the second quarter of ’22, a significant delay from the previously announced target date in ’21, which itself was a delay from the original late ’20 launch date.
Ariane 6 however has not succeeded in cutting costs enough to match its competitor SpaceX, and thus it continues to have trouble attracting customers, even among ESA’s partner nations that it is meant to serve. These issues have led to rumors that ESA is already looking to either significantly upgrade Ariane 6 (before it even flies), or replace it entirely wit a new re usable rocket.
OSIRIS-REx completes storage of Bennu sample
OSIRIS-REx has now completed placing its sample from the asteroid Bennu in the Sample Return Capsule that will bring it back to Earth.
On the afternoon of Oct. 28, following the backout check, the mission team sent commands to disconnect the two mechanical parts on the TAGSAM arm that connect the sampler head to the arm. The spacecraft first cut the tube that carried the nitrogen gas that stirred up the sample through the TAGSAM head during sample collection, and then separated the collector head from the TAGSAM arm itself.
That evening, the spacecraft completed the final step of the sample stowage process –closing the SRC. To secure the capsule, the spacecraft closed the lid and then fastened two internal latches. As of late Oct. 28, the sample of Bennu is safely stored and ready for its journey to Earth.
Because they decided it was better to store the sample immediately and not risk losing it, they were unable to do the spin test that would told them how much sample they obtained. For this reason we will not know the amount until the sample capsule is opened here on Earth, after its return on September 24, ’23.
UPDATE: You can watch if short movie of the Sample Return Capsule closing here.
Twelve graphs prove masks are useless against COVID-19
Link here. The graphs, covering many more regions, countries, and states then the similar graphs I have posted previously, show that masks have zero effect on preventing the spread of the Wuhan virus. In some places infections rose after mask mandates were imposed. In others they declined. And the pattern showed little difference between places with or without mask mandates. As the author notes quite correctly,
Masks are not merely a small inconvenience. They have inadvertently become a key impediment to returning to a more normal life, a desirable goal for those seeking to twist the pandemic for political and electoral purposes.
Masks dehumanize us, and ironically serve as a constant reminder that we should be afraid. People can now be spotted wearing masks while camping by themselves in the woods or on a solo sailing trip. They have become a cruel device on young children everywhere, kindergarten students covered by masks and isolated by Plexiglas, struggling to understand the social expressions of their peers. Face coverings are causing real harm to the American psyche, provide little to no medical benefit, and distract us from more important health policy issues.
The mask dogma had many cracks in it from the start. For one, the U.S. surgeon general and the Centers for Disease Control both previously said that “masks are NOT effective in preventing [the] general public from catching coronavirus,” so they were already starting with a credibility deficit. Furthermore, many officials have been frequently caught without masks when they think the cameras are off them. Dr. Anthony Fauci, for example, has been caught doing this multiple times.
Take a look at the article and the graphs. They will make you feel really silly and stupid when you next put that mask on.
I say, throw the mask away. I don’t wear one, and won’t. I won’t bow to the scare tactics of politicians and incompetent and lying health officials. I have also found I pretty much can go anywhere I want without that mask. Almost no one questions me, and the few times someone has, I simply tell them I don’t wear for medical reasons, and they back off, leaving me alone.
If more people did as I do, so that those more timid began to see more people maskless and free, more people would be willing to do that same. We might actually begin to see people’s faces again, and live in a manner humans were meant to live.
