Max Ehrman – Desiderata

An evening pause: An excellent meditation for beginning the weekend. From the Youtube webpage:

Max Ehrmann was an American attorney and poet who often wrote on spiritual themes. During his life, he contributed great thoughts to our literary lexicons, blending the magic of words and wisdom with his worthy observations.

Desiderata, which means “things that are desired,” was written by Max Ehrmann “because it counsels those virtues I felt most in need of.”

I think the reading was a bit slow. I think it works better at either 1.25 or 1.5 speed.

Hat tip Cotour.

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

Deep inside the youngest flood lava event on Mars

Deep inside the youngest flood lava event on Mars
Click for full image.

Cool image time! Today we return to the Athabasca Valles flood lava event, believed to be the youngest major lava event on Mars that I highlighted in a cool image last week.

Then, I showed two meandering lava flows near the edge of this Great Britain-sized flood lava plain, produced 600 million years ago in only a matter of weeks. Today, we take a look deep within the lava plain. The photo to the right, rotated, cropped, and reduced to post here, was taken on May 6, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label “a lava-crater interaction.”

In plain English, we are looking at a crater that has been inundated by the flood lava, filling it.

Today’s blacklisted American: USC professor suspended because one common Chinese word he was teaching sounded like the “N-word”

Greg Patton, blacklisted for being a good teacher
Greg Patton, blacklisted by USC for being a good teacher

The modern dark age: Today’s blacklist story is in a sense a follow-up of my blacklist story from yesterday, as it clearly shows that the fraternities which broke free of supervision from the University of Southern California (USC) had good reason, and that (as I speculated) one of the main reasons they did so was because of USC’s woke and racist policies.

Today we discover that USC has forced a communications professor specializing in Asia, Greg Patton, to stop teaching because during one virtual class he was explaining the innocent reason why — to English speakers — the Chinese seem to say a racial slur repeatedly. Apparently, the Chinese phrase “那个” (nèi ge), which approximately means “that one” or more simply “um”, is used in Chinese as a filler word, similar to “um,” “ur” in English.

Patton was trying to explain this to his class during a virtual session. Below is embedded that specific moment that has now caused him so much trouble:

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.

Starlink being tested in Antarctica

Capitalism in space: The National Science Foundation (NSF) has begun testing a single Starlink terminal at its McMurdo station in Antarctic, with the hope that the service can improve communications at the station significantly.

Everyone at the base shares a 17 Mbps link, according to the United States Antarctic Program, which severely limits what people can do. The station actually blocks people from using high-bandwidth apps like Netflix, cloud backups, and video calls, with the exception of once-weekly Skype or FaceTime sessions at a public kiosk or mission-critical communications.

The addition of Starlink probably doesn’t mean that McMurdo residents will be able to hold a Netflix movie night or anything — the terminals can handle around 50-200 Mbps, which still isn’t a ton to go around, even during the winter when far fewer people are at the base — but it could help make transferring important scientific data off of the icy continent easier.

According to SpaceX’s plans, this new service in Antarctica means that by year’s end Starlink will be available on all seven continents.

New theory: Saturn’s rings came from a lost and destroyed moon

The uncertainty of science: According to a new computer simulation, scientists have proposed that the reason Saturn’s rings are tilted 27 degrees is because they were created by the destruction of a moon 160 million years ago, an event that was also linked to the way the orbits of Saturn and Neptune interact, combined with the on-going slow evolutionary changes in Titan’s orbit around Saturn.

Wisdom and his colleagues believe Saturn acquired its tilt because of a peculiar synchronicity: the precession of Saturn’s spin axis—the way it wobbles like a top with a particular rhythm—is suspiciously in tune with a precession in Neptune’s orbit. If Saturn and Neptune were trapped in this resonance, Saturn’s tilt would be “kind of vulnerable to other forces that could cause it to change,” says Rola Dbouk, an MIT graduate student in planetary science. In 2020, Cassini scientists discovered what the study team thinks is that external stimulus: Titan, Saturn’s largest moon, is migrating away from Saturn by 11 centimeters a year. In a study published today in Science, Dbouk, Wisdom, and colleagues show how Titan’s migration, in combination with the Saturn-Neptune resonance, could have ratcheted up Saturn’s tilt over the course of 1 billion years.

The work also yielded a potential explanation for the origin of Saturn’s rings. Using Cassini’s measurements of Saturn’s gravitational fields to model the planet’s interior structure, the researchers refined calculations for the wobble of Saturn’s spin axis and found it is no longer in sync with Neptune. “Something kicked it out of the resonance,” Dbouk says. They first ruled out the possibility that chaotic changes in the orbits of some of the largest of Saturn’s dozens of moons could be responsible. But when they added another moon to the mix, things got interesting.

In simulations, the researchers included an object about the size of Iapetus, Saturn’s third largest moon, orbiting about 43 Saturn radii out—between the orbits of Titan and Iapetus. They found this moon could have provided the necessary nudge to the resonance if it were suddenly knocked from its orbit because of chaotic interactions with its neighbors about 160 million years ago.

To say that this theory is uncertain is no different that saying the sky is blue. It is so uncertain that it is difficult to take it seriously. It could be right, but as one scientist quoted at the article noted, there is no way to test it.

CAPSTONE update: Situation improved but not resolved

Advanced Space, the company operating the CAPSTONE smallsat lunar orbiter that is on the way to the Moon, has issued a hopeful update on the efforts to regain full control of the spacecraft after it began tumbling out-of-control on September 8th.

The communications situation has dramatically improved, the power state of the spacecraft appears to be sufficient for continuous (duty cycled) heating of the propulsion system which dropped below its operational temperature, Over the past few days, CAPSTONE’s power – though limited by the orientation of the spacecraft in its spin relative to the Sun – appears to be sufficient for heating of the propulsion system. When the spacecraft propulsion system temps are at +5C for 12+ hours the system will be further evaluated for use in the recovery operation. Information on the cause of the anomaly has been obtained and is being evaluated, and recovery plans that mitigate risk of further anomalous behavior are being developed. We do not have a timeline for a recovery attempt.

It appears they have not yet done the detumble maneuver that the engineers think will bring the spacecraft back to nominal operations. However, the spacecraft appears to also be on its planned course towards the Moon, so all signs suggest a full recovery is likely.

Rocket Lab successfully launches commercial radar satellite

Capitalism in space: Rocket Lab today successfully used its Electron rocket to place a commercial radar Earth observation satellite into orbit.

This was the company’s 30th successful launch. As of this writing, the satellite itself has not yet deployed.

The leaders in the 2022 launch race:

41 SpaceX
37 China
11 Russia
7 Rocket Lab
5 ULA

American private enterprise now leads China 57 to 37 in the national rankings, and the entire world combined 57 to 56. The 57 successful American launches so for this year ties for third place with 1964 and 1967 for launches in a year. The record number of U.S. launches in a single year was 70, in 1966. That record should almost certainly be topped this year.

SpaceX will once again attempt to launch 54 Starlink satellites later tonight, having cancelled several times this week due to weather.

Pushback: Fraternities break free from USC’s draconian supervision

What USC wants its students to become
What USC wants its students to become

Bring a gun to a knife fight: Faced with the university’s arbitrary rule that shut them down “without explanation or cause,” ten of the fourteen fraternities that serve the students at the University of Southern California (USC) have broken their affiliation with the university and formed their own oversight body.

Not surprisingly, the university immediately implied that these fraternities were acting to encourage “sexual assaults,” “drug abuse,” “mental health abuse,” and “underage drinking,” and should be blacklisted by USC students. Officials from the new independent council immediately disputed these slanderous claims:

“I want to say unequivocally that no, we are not disaffiliating to dodge these social event policies that were put into place,” Harrison Murphy, a representative from the new council, told The Los Angeles Times.

“Murphy said members that separated from USC did so because they felt the university’s policies toward Greek organizations were unfair and flawed,” The Los Angeles Times reported. “For instance, he said, USC banned all social events from November 2021 through January 2022 even for fraternities that had done no wrong.”

A look at university’s long and complex policy [pdf] for supervising these fraternities makes if very clear why so many have told the university to go jump in a lake. The number of inspections, meetings, and consultations required, combined with a lot of odious paperwork, appears absurdly unreasonable and costly. The policies also apparently allowed the school to shut a fraternity down merely on hearsay accusations, based on incredibly vague standards. Note the highlighted words below:

Billionaire wants to build spinning space station for testing artificial gravity

Capitalism in space: Billionaire Jed McCaleb, who earned billions in software and cryptocurrency, has started a company dubbed Vast to develop and build a spinning space station for testing the pros and cons of artificial gravity.

McCaleb is self-financing at the moment, though he hopes to turn his station eventually into a money-making proposition. His company is also right now very small, but he clearly is going for the best in who he is hiring:

Currently, the company has about 20 employees, including Kyle Dedmon, former SpaceX vice president for construction and facilities; Tom Hayford, a systems engineer who has worked for Relativity Space and SpaceX; Molly McCormick, a former SpaceX human factors engineer and Honeybee Robotics program manager; and Colin Smith, a former SpaceX propulsion engineer. In addition, former SpaceX vice president Hans Koenigsmann is advising the company.

This new private space station joins by my count the four other American private space stations now proposed, including Axiom’s station, a partnership led by Sierra Space building Orbital Reef, Nanorack’s Starlab station, and Northrop Grumman’s upgrade station based on its Cygnus freighter.

That’s five private space stations under development in the United States. And there could be others that I have missed.
