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

The mountains of Mars

Curiosity's view south July 24, 2024

Cool image time! The panorama above, created from two left navigation camera photos taken by the Mars rover Curiosity on July 24, 2024 (here and here), looks south up the flanks of Mount Sharp as well as into the Gediz Vallis channel that the rover has been exploring for the past year or so.

The overview map to the right provides us a wide view of Gale Crater and the rover’s entire journey there since it landed on Mars in 2012. The blue dot marks its present position. The yellow lines indicate the approximate view in the panorama above. The red line indicates the planned route, leaving Gediz Vallis to take a parallel canyon uphill to the west.

Curiosity during its dozen years on Mars has traveled just under 20 miles and climbed about 2,500 feet. The peak of Mount Sharp however is still about 26 miles away and about 16,000 feet higher.

The rover is now at the very base of the sulfate-bearing unit, which is why last month it literally ran over some rocks that were its first detection of pure sulfur crystals on Mars. Once Curiosity reaches that sulfate-bearing unit it is likely going to be an extremely alien landscape, comprised of rock that is suffused everywhere with sulfur. Such landscapes are likely impossible on Earth due to its oxygen-rich atmosphere. The sulfur and oxygen would interact, forming different molecules.

Judge issues injunction against NLRB in favor of SpaceX

NLRB logo

A U.S. federal district judge today issued an injunction against the National Labor Relations Board (NLRB), blocking any further action on its complaint against SpaceX until the courts rule on the constitutionality of that complaint, accepting SpaceX’s position that the NLRB’s decision to suspend that complaint pending a court decision was irrelevant.

The NLRB has sued SpaceX, claiming it had violated the labor rights of several former employees because it fired them for criticizing Musk publicly. SpaceX responded by suing the NLRB itself, claiming the law which founded it and allowed it to act as prosecutor, judge, and jury in all cases while also limiting the President’s ability to fire its officials was unconstitutional.

As the case moved through the courts, the NLRB suspended its case against SpaceX. The company however demanded this injunction as well, since it considered that suspension merely a ploy that could be rescinded at any time.

Judge Albright ruled in favor of SpaceX and imposed an injunction as the case proceeds. He said the ruling came in part because of the U.S. Court of Appeals for the Fifth Circuit’s ruling that restrictions on removal for administrative law judges in the Securities and Exchange Commission are unconstitutional.

You can read the judge’s decision here [pdf]. This quote from it however is very telling:

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.

Webb takes infrared image of exoplanet

A Jupiter-sized exoplanet imaged by Webb
Click for original image.

Cool image time! Using the Webb Space Telescope, scientists have taken an infrared false color image of a multi-Jupiter-sized exoplanet located only twelve light years away and orbiting the K-type star Epsilon Indi A.

That picture, cropped, reduced, and sharpened to post here, is to the right. The light of the star, indicated by the star symbol, has been blocked by Webb’s coronagraph, the size of which is shown by the dashed circle. The exoplanet is the orange blob to the left.

[This exoplanet] is one of the coldest exoplanets to be directly detected, with an estimated temperature of 35 degrees Fahrenheit (2 degrees Celsius) — colder than any other imaged planet beyond our solar system, and colder than all but one free-floating brown dwarf. The planet is only around 180 degrees Fahrenheit (100 degrees Celsius) warmer than gas giants in our solar system. This provides a rare opportunity for astronomers to study the atmospheric composition of true solar system analogs.

The data also revealed that the exoplanet is twice as massive as expected and has a slightly different orbit than expected based on previous less precise data.

SpaceX’s contract to de-orbit ISS reveals the inability of the older space companies to compete

Link here. The article goes into detail about the bidding process that led to SpaceX winning the contract $843 million fixed-price contract to build a specialized Dragon capsule to dock with ISS and de-orbit it. While its focus is on the refusal of the older companies (Northrop Grumman, Lockheed Martin, and Boeing) to sign the fixed-price contracts that NASA now prefers and that SpaceX can handle with no problem, it was this section that struck me the most:

SpaceX’s bid price was $680 million. The source selection statement did not reveal a price for Northrop’s bid other than saying it was “significantly higher.” Based on NASA’s budget request, Northrop’s bid was likely approximately twice as high.

But SpaceX did not just win on price. Its “mission suitability” score, effectively its technical ability to design, develop, and fly a vehicle capable of deorbiting the space station, was 822, compared to Northrop’s score of 589. SpaceX’s approach had one weakness, compared to seven weaknesses in Northrop’s bid, according to NASA evaluators.

Finally, the selection was also based on past performance by the contractors. SpaceX’s performance was rated as “very high,” given how it has delivered with the Cargo and Crew Dragon spacecraft and its Falcon 9 rocket. Northrop’s performance on Cygnus and its various rockets was given a “moderate” rating. Overall, the NASA evaluators expressed a “very high level” of confidence in SpaceX being able to complete the mission, whereas a “moderate level” of confidence was expressed in Northrop.

In other words, Northrop not only couldn’t do the job as cheaply and wasn’t even willing to do it at a fixed price, its technical performance has not been that good either.

The article focuses rightly on the present lack of any viable competitors to SpaceX, and the problems this raises for the entire American aerospace industry. I want to point out how this situation reveals a much more fundamental problem with the industry itself. The established aerospace industry is not only doing poor work, it is overcharging for it.

Or to put it more bluntly, it is unwilling or unable to compete. Relying on businesses with such bankrupt attitudes is not a good way to get anything done.

The hope had been that the newer startups (Rocket Lab, Blue Origin, Relativity, Firefly, etc) would pick up this slack, but except for Blue Origin the rocket capabilities of these companies are just not big enough yet to do it. Blue Origin’s proposed New Glenn rocket and associated spacecraft could do the job, but the company has demonstrated for the past decade its desire to emulate the older and failing big space companies rather than a new fresh face.

The new companies, given time, could solve this problem, since they are all willing to innovate and compete, but the apparent increase in the regulations imposed by the FAA and other government agencies in the past two years suggests they will be squelched as well.

Unless something changes, the U.S. is not going to see the space renaissance that seemed so promising only two years ago.

Axiom hires British astronaut Tim Peake

Axiom has now added British astronaut Tim Peake to its staff, making him the fourth astronaut after Michael Lopez-Alegria, Peggy Whitson, and Koichi Wakata working for the commercial space station and space tourism company.

The decision appears to be in connection with Axiom’s agreement with the UK Space Agency to fly an all-British manned commercial mission in exchange for $19 million in government funding. NASA regulations require any commercial mission that docks with ISS to include as a company commander an experienced astronaut. By hiring Peake Axiom fulfills this requirement.

No date for this four-person two week mission to ISS has been announced. Nor have any other passengers been named. It is very possible this announcement today is a PR effort by Axiom to drum up interest from potential British customers because the earlier announcements have possibly failed to do so.

Scientists find hydrogen molecules in Chang’e-5 lunar samples

According to China’s state-run press, scientists analyzing the lunar samples brought back by its Chang’e-5 lander have detected extensive “hydrated” molecules in Moon’s regolith.

The mineral’s structure and composition bear a striking resemblance to a mineral found near volcanoes on Earth. At the same time, terrestrial contamination or rocket exhaust has been ruled out as the origin of this hydrate, according to the study.

The Chinese article keeps referring to these molecules as a form of “water molecules” but that is dead wrong. These are mineral molecules that simply have hydrogen as a component. There is no water here.

The discovery suggests that the detection of hydrogen on the surface of the Moon, both in the permanently-shadowed craters at the poles as well as lower latitudes, might not be water at all, but hydrated minerals. If so, the Moon is going to be a much more difficult place to establish colonies or even research bases, as getting water (and hydrogen and oxygen) is going to require a much more difficult mining and processing effort.

For several years the data has increasingly pointed in this direction. And for several years I have noticed a strong unwillingness of scientists and the press to recognize the trend (as illustrated by the above article’s false insistence that these are water molecules). Water ice has not been ruled out yet in the permanently-shadowed craters at the poles, but the evidence is mounting against it.

I suspect this reluctance is fueled by a desire to not say anything that might discourage exploration of the Moon, and the possibility of water there has been the main driver for all the recent lunar exploration programs. I can’t play that game. As much as I want humanity to explore the Moon and the solar system, we mustn’t do it based on lies. The facts need to be reported coldly.

Everything connected to Washington and the Democratic Party stinks like a rotting corpse

I didn’t post an essay yesterday because I could not figure out what to write. The insanity of the past week, with Trump’s near assassination, the horrendous incompetence of the Secret Service, the sudden disappearance of Joe Biden, and then his somewhat mysterious withdrawal from the candidacy of the presidency, all presented too many topics that were changing too fast to digest.

Vultures eating carrion

All I can now take from these events is an impression of a rotting corpse, the Democratic Party, that the voters should have buried decades ago. Instead, the voters have propped it up, allowing its stink to spread until it has poisoned everything related to American government and the noble but now dying principles that formed it.

For example, it now appears that the colossal security failure on July 13th during Trump’s Pennsylvania rally was the result of providing the Secret Service too few resources, forcing it to depend more on local authorities than normal. The Secret Service and the local police then showed themselves to all be utterly incompetent. It appears communications between these different government agencies was poor or non-existent. The local people were supposed to secure the top of the roof where the assassin eventually placed himself, but decided instead to go inside the building because the roof “was too hot.”

Unfortunately, it seems this decision wasn’t conveyed to the Secret Service properly. It therefore appears Crooks was able to station himself on the roof and fire at Trump because the Secret Service thought he was a local police sniper.

At least, that’s my interpretation of the facts, as presently understood. » Read more

More great hiking on Mars

More great hiking on Mars
Click for original image.

Today’s cool image takes us to another place on Mars where future colonizers will find the hiking breath-taking. The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on April 18, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The camera team labeled it merely as a “terrain sample,” indicating it was not taken as part of any specific research project request, but to fill a gap in the schedule in order to maintain the camera’s proper temperature. When the MRO team does this, they try to pick interesting sites, sometimes successfully, sometimes not.

In this case the image captured the sharp nose of a 2,100-foot-high mesa which to my eye immedately said, “I want to hike a trail that switchbacks up that nose!” Ideally, the trail would then skirt the edge of the mesa, then head up to the top of that small knoll on the plateau. Though only another 200 feet higher or so, the peak would provide an amazing 360 degree view of the surrounding terrrain.
