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 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
Sand dunes inside the Martian north polar icecap
Today’s cool image returns to the Martian north pole. The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on July 3, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the top of a ridge near the edge of that icecap, with dunes visible in the hollow several thousand feet below.
The angle of this picture does not show us the many layers on the cliff leading down to those dunes. It does show evidence, however, of the top few layers on the flat crest of that ridge. The white lines delineate those layers, each line marking the edge of a series of wide terraces.
The dunes in the canyon below are of interest because their source is likely the dust that is mixed into thick icecap’s ice. As that ice sublimates away on the face of the cliff, the dust falls into the canyon, where it is trapped.

Both before and after its Starship launch yesterday, SpaceX also completed two Falcon 9 launches
The past 24 hours SpaceX did more than complete its stunningly successful tenth launch of its Starship/Superheavy rocket. The company also launched its Falcon 9 rocket twice from opposite coasts.
First it launched a commercial Earth observation satellite, built by the European company OHB Italia for Luxembourg, its Falcon 9 lifting off from Vandenberg in California. The first stage completed its 27th flight, landing back at Vandenberg..The launch also placed several smallsats in orbit as well.
Then this morning, ten hours after the Starship/Superheavy launch, another Falcon 9 rocket lifted off from Cape Canaveral, placing another 28 Starlink satellites in orbit. The first stage completed its second flight, landing on a drone ship in the Atlantic.
After including all three SpaceX launches, this is the leader board for the 2025 launch race:
107 SpaceX
48 China
12 Rocket Lab
11 Russia
SpaceX now leads the rest of the world in successful launches, 107 to 84.

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.
The most powerful rocket ever, built and financed by a private company, has a near perfect tenth test flight
Liberty quite literally enlightening the world
In the tenth test orbital flight of SpaceX’s Starship/Superheavy rocket today, the company has what appeared to be a near perfect flight.
First the Superheavy booster worked as intended, completing a new return configuration to reduce stress, completing a soft vertical splashdown in the Gulf of Mexico. During the landing the company tested using backup engines instead of the normal engines to see if this would work in future situations where an engine failed. This worked.
Next, Starship reached its low orbit, intended to end over the Indian Ocean. Unlike the last two test flights, the ship functioned as planned.
Starship completed a full-duration ascent burn and achieved its planned velocity, successfully putting it on a suborbital trajectory. The first in-space objective was then completed, with eight Starlink simulators deployed in the first successful payload demonstration from Starship. The vehicle then completed the second ever in-space relight of a Raptor engine, demonstrating a key capability for future deorbit burns.
Moving into the critical reentry phase, Starship was able to gather data on the performance of its heatshield and structure as it was intentionally stressed to push the envelope on vehicle capabilities. Using its four flaps for control, the spacecraft arrived at its splashdown point in the Indian Ocean, successfully executed a landing flip, and completed the flight test with a landing burn and soft splashdown.
Some burn through damage on Starship was seen, but relatively little, despite the decision to stress the flaps and the reduce the coverage of the heat shield. The landing was on target, an even more impressive achievement.
As must be repeated over and over, this was a test flight of prototypes. The final version of both Superheavy and Starship will not be the same. The flight tested preliminary designs and capabilities, the data obtained to then be used to redesign and revise both components of the rocket.
The most significant aspect of this test flight however is its funding. » Read more

- The Miura-5 rocket’s second-stage engine for the Spanish rocket startup PLD is now ready for qualification testing
The company had been targeting the first launch of Miura-5 before the end of 2025. It appears that launch will likely slip to early 2026.
- On this day in 1989, Voyager 2 made its closest approach to Neptune
It passed within 3,000 miles of the planet, and to this day is still the only spacecraft to get a close look.
- On this day in 2003, NASA launched the Spitzer Space Telescope, the fourth in the Great Observatory program
An infrared telescope, Spitzer was a precursor to the Webb Space Telescope. It was named after Lyman Spitzer, who conceived the Hubble Space Telescope and was central in getting it built.

The beauty of Mars’ many-layered northern icecap
Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on July 1, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The science team labels it clumsily as “North Polar layered deposits structural geology in icy layers”. What we see are the many layers that make up the north polar cap, produced by the red planet’s many climate cycles that scientists think Mars has undergone over the eons as the red planet’s rotational tilt, or obliquity, rocked back and forth from 11 degrees inclination to as much as 60 degrees. At the extremes, the ice cap was either growing or shrinking, while today (at 25 degrees inclination) it appears to be in a steady state.
These layers are a mixture of ice and dust. The variations from dark to light likely indicate changes in the amount of dust in the atmosphere. Dark layers suggest the atmosphere was more dusty due to volcanic eruptions. Light layers suggest the planet’s volcanic activity was more subdued.
At least that’s one hypothesis.

On the road today
Diane and I are on the road today, leaving the Grand Canyon, which remains as grand as ever, and heading to Colorado to visit friends we haven’t seen since before the COVID panic.
Thus, I will likely not be able to watch today’s third attempt by SpaceX to complete the tenth launch of its Starship/Superheavy rocket, as it happens.. (Live stream can be found here.)
Once settled in Colorado I will catch up. Like you all, I have my fingers crossed that the launch will go off as hoped with a largely successful test flight.
One fortunate thing that has occurred during the previous two launch attempts in the past two days is that it appears the protest of boats proposed by a Mexico radical activist group to block the launch has so appeared to be a bust. There has been no indication of any boats entering the launch range in the Gulf of Mexico, and if any have tried, it appears they have been removed quickly.

Webb and SPHEREx space telescopes observe interstellar Comet 3I/Atlas
Both the Webb Space Telescope and the newer SPHEREx space telescopes have now been aimed by scientists at the interstellar comet 3I/Atlas.
According to the paper describing the Webb results, the comet’s coma is dominated by carbon dioxide gas.
The SPHEREx results [pdf] also show a strong signal of carbon dioxice in the coma, as well as a strong signal of water ice in its nucleus.
These results, along with all the observations by multiple other telescopes in space and on the ground, are in line with what is expected from a comet, with the kind of unique differences expected from each object. There is nothing seen so far from the data to suggest anything alien about it, despite the claims of some pubicity-seeking scientists who don’t even specialize in comet research.
The big scientific discovery here is that this interstellar comet is so much like comets that come from our own solar system. The implication is that other solar systems have great similarities to our own. .

Tenth orbital test flight of Superheavy/Starship scrubbed due to weather
The tenth orbial test flight of SpaceX’s Starship/Superheavy rocket was scrubbed tonight due to bad weather.
The countdown got down to T-40 seconds before scrubbing. Mission control then ran the count down to T-10 to complete instead a full dress rehearsal countdown before fully scrubbing.
Expect them to try again tomorrow, though this has not yet been confirmed.

Wind-eroded terrain on the edge of Mars’ largest volcanic ash field
Cool image time! The picture to the right, cropped and sharpened to post here, was taken on July 2, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
Labeled simply as “wavy terrain” by the MRO science team, it shows a relatively flat plain of hollows and terraced ridges that suggest the prevailing winds come from the west-southwest. As they blow, they slowly cause the layers of material to peel away, exposing those terraces.
This wavy landscape extends for many miles to the west, covering a region 135 by 160 miles in area. The layering and wavy nature of the terrain suggests the material here is fragile and easily peeled away by the winds of Mars’ very thin atmosphere. Think of the sandstone that forms Monument Valley and Canyonlands in the southwest United States, shaped almost entirely by wind.
And in fact, the overview map below confirms this.

Contact re-established with Jupiter probe Juice after a month
After losing all communications with Europe’s probe Juice on July 16th, on its way to Jupiter, engineers have finally re-established communications and found the spacecraft to be in sound condition.
Six attempts to steer the medium-gain antenna back towards Earth were unsuccessful. Recovery efforts continued overnight, lasting almost 20 hours and focusing on manually powering up Juice’s onboard communication systems.
Eventually, a command succeeded in reaching Juice and triggering a response. The command activated the signal amplifier that boosts the strength of the signal that Juice sends towards Earth. Contact was re-established, and Juice was found to be in excellent condition. No systems had failed, and all telemetry was nominal.
The root cause was traced to a software timing bug. The software function that switches the signal amplifier on and off relies on an internal timer. This timer is constantly counting up and restarts from zero once every 16 months. If the function happens to be using the timer at the exact moment it restarts, the amplifier remains switched off, and Juice’s signal is too weak to detect from Earth.
The spacecraft has a scheduled fly-by of Venus on August 31st, so regaining contact was critical. It has already done one Earth fly-by, with two more scheduled, before it arrives in Jupiter orbiter in July 2031.

Misconduct alleged in management of Square Kilometer Array in Australia
According to a whistle-blower, there has been financial misconduct in international management of the Square Kilometer Array (SKA) being built in remote western Australia.
In response to the disclosure, a copy of which has been seen by the Guardian, Zerbi has initiated an investigation into claims that public funds from member states have been lost through trading accounts – and then covered up by the organisation through the shuffling of funds internally.
At the centre of the misconduct allegations is a claim that at least £12m (A$25.1m) was lost through investment in three money market funds, with one fund allegedly losing 45% of its value. The Guardian has seen balance sheet extracts and statements that appear to confirm the investments by the SKAO, which is headquartered at the Jodrell Bank Observatory near Manchester.
The report also calls for an investigation into claims funds are being shifted within the organisation, and currency fluctuations being fabricated to conceal these losses from the governing council overseeing the project.
The project is significantly overbudget.
SKA management denies the alliegations, though it has at the same time begun its own investigation.
This corruption likely stems from the project’s international setup, which apparantly makes it “immune from normal legal processes and exempt from paying tax.” In addition, “international staff employed on the project in Australia are hired on diplomatic visas.” Under these conditions we should not be surprised if some hanky-panky with large sums of money took place.

Off to the Grand Canyon and Colorado
Diane and I are taking a short six-day vacation up north, beginning today. This is actually our first trip together since the COVID panic, and we are both looking forward to it.
Our original plan had been to do a hike to the bottom, stay overnight at Phantom Ranch, and then hike out the next day. For a variety of reasons, including the fire on the north rim that has closed Phantom Ranch till the late fall, we shifted our plans to spending a few days at the south rim. We will hike the rim trail one day (something Diane hasn’t yet done), and do other stuff the next. We will then head to Colorado to visit friends.
I will be posting while I am on the road, but don’t expect long essays.

August 22, 2025 Quick space links
Courtesy of BtB’s stringer Jay, who apologizes for the lateness due to a hectic day at work. This post is also an open thread. I welcome my readers to post any comments or additional links relating to any space issues, even if unrelated to the links below.
- Chinese pseudo-company Nayuta Space releases movie animation showing how its proposed first stage will return to Earth
It would land horizontally, not vertically. Assuming this fantasy ever actually happens.
- Astronomers prove that millimeter radiation is generated close to the core of a supermassive black hole
Need I say it?
- India’s space agency ISRO touts a fullscale model of the 1st module of India’s Bharatiya Antariksh Station (BAS)
The full station will have five modules, assembled in orbit from ’28 to ’35, if all goes as scheduled.
- 60 years ago Gemini-5 was the first mission to use fuel cells to power a manned spacecraft
Proving out that technology was essential for the Apollo missions, as NASA had determined that solar power was not yet ready.

Saturday Night Live – Washington’s Dream
SpaceX gets major tax credit for the jobs its new Starship factory will create.
Because SpaceX’s new Starship factory, dubbed Gigabay, will create more than 500 new jobs in the Boca Chica region, the Starbase city commission this week awarded the company a sales tax refund valued as much as $3.75 million.
Gigabay will create about 630 new jobs, according to information Barrera showed the City Commission. That number included 315 entry-level jobs, which pay nearly $50,000 a year; 277 staff jobs, which pay nearly $90,000 a year; and 26 manager positions, which pay about $164,000 a year. … At least 25% of the jobs must be filled by veterans, residents of the enterprise zone or people who are considered economically disadvantaged.
SpaceX may receive a sales tax refund of $7,500 per job if the company invests $250 million. The program is capped at 500 jobs, allowing SpaceX to receive a maximum of $3,750,000.
Once again, the opposition to SpaceX does not come from the general public, which overwhelming supports what the company is doing in south Texas because of the wealth it is bringing to the region. The only opposition comes from fringe and very tiny leftist activist groups who oppose anything new, and specifically hate Elon Musk because he backed Donald Trump in last year’s election.
Sadly, those fringe groups are also backed by the propaganda press, which gives them a loud bullhorn they don’t deserve. It is imperative that Texas politicians recognize these facts, and not let that bullhorn bully them into actions detrimental to their constituents.

Texas brewery tries brewing beer and growing barley on ISS
A Texas brewery dubbed Starbase Brewing (no connection to SpaceX) has just completed an experiment on ISS where it tried to brew beer in weightlessness as well as grow barley in simulated Martian soil.
Starbase Brewing — unrelated to Elon Musk’s space company or its South Texas city of Starbase — sent its MicroBrew-1 and OASIS experiments to the International Space Station aboard a SpaceX mission Aug. 1. They came back aboard a SpaceX Dragon spacecraft that splashed down eight days later off the coast of California.
…OASIS, short for “Optimizing Agriculture in Simulated Interplanetary Soils,” is the result of a partnership between the beer maker, Texas A&M AgriLife and Jaguar Space, a Colorado bioastronautics firm. According to Argroves, who launched the company in 2020, the goal was to grow barley in a mixture of Martian soil simulant with a byproduct of beermaking called Brewer’s Spent Grain and microbes.
The MicroBrew-1 experiment attempted to ferment beer, mixing “eight containers loaded with half wort — the sugary liquid extracted from malted grains — and half yeast.”
The company is far from manufacturing space-grown beer, but its founder seems focused on being the first brewery selling beer on Mars.

Junk science now dominates the reporting of the propaganda press
The Sciences, when the goal of science journalism
was to report real discoveries
When I started my career as a science journalist in the early 1990s, Peter Brown, the editor of award-winning magazine The Sciences (now sadly discountinued), assigned me the job of writing short news pieces. He pointed at a three-foot-high pile of press releases, and suggested I go through them to find some scientific discovery worth reporting.
As I went through this pile each month, I found that 90% described results that while interesting certainly did not merit any news coverage. Many described theories that “might” or “could” be true, hardly examples of solid new knowledge. I would find a handful of releases worth a news report, while the remaining 90% would get thrown in the dumpster.
Unfortunately, limited space in the magazine often meant that only one of the stories I thought worthwhile would be reported, but it also meant the story we picked was of real significance. The reader was guaranteed to read about important research results, because the technology then forced us to be discriminating.
That was then. Today, things are very different. The web allows modern news outlets to report about practically every press release they get. Nothing gets thrown away. If anything, new outlets today relish reporting on the least significant science results, merely because the scientists speculate about some amazing final events that “might,” “could,” or “may” happen, if their theories are right. The press eats this junk science up, because it produces great clickbait that, while as vapid as cotton candy, sounds really cool or exciting. That these speculations have no basis in reality is irrelevant.
To give you an idea of what I mean, here are a few examples from our modern propaganda press that I have gathered in just the past week:
