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, any other book seller, or direct from my ebook publisher, ebookit. 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
SpaceX launches twice today from different Florida launchpads
SpaceX today successfully launched twice. First a Falcon 9 rocket lifted off from Kennedy Space Center in Florida, placing a South Korean communications satellite in geosynchronous orbit. The first stage completed its 23rd flight, landing back at Cape Canaveral.
Then, several hours later, a Falcon 9 lifted off from Cape Canaveral, placing 24 Starlink satellites in orbit. The first stage completed its 12th flight, landing on a drone ship in the Atlantic.
UPDATE: China also completed a launch earlier today, its Lijian-1 rocket lifting off from its “commercial” launchpad at its Jiuquan spaceport in northwest China. No word on where the lower stages crashed inside China. The payload was fifteen satellites, including a remote-sensing satellite for Oman.
The leaders in the 2024 launch race:
112 SpaceX
51 China
13 Russia
12 Rocket Lab
American private enterprise now leads the rest of the world combined in successful launches 130 to 76, while SpaceX by itself leads the entire world, including American companies, 112 to 94.

Linda Ronstadt – Blue Bayou
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 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.

A defunct satellite is now in an unexpected orbit, and no one knows how it got there
Skynet-1A, a British satellite launched in 1969 and out of commission since the 1970s, has now been found in an unexpected location in geosynchronous orbit, and no one knows how it got there.
Launched in 1969, just a few months after humans first set foot on the Moon, Skynet-1A was put high above Africa’s east coast to relay communications for British forces. When the spacecraft ceased working a few years later, gravity might have been expected to pull it even further to the east, out over the Indian Ocean.
But today, curiously, Skynet-1A is actually half a planet away, in a position 22,369 miles (36,000km) above the Americas. Orbital mechanics mean it’s unlikely the half-tonne military spacecraft simply drifted to its current location. Almost certainly, it was commanded to fire its thrusters in the mid-1970s to take it westwards. The question is who that was and with what authority and purpose?
The article attempts to suggest the orbit change was done for some nefarious purpose, but the most likely explanation is that at some point the British engineers who operated it ordered the required engine burns, but the records of that work are now lost.
Though the present location poses some problems for other geosynchronous satellites, Skynet-1A also now offers a great opportunity for a mission demonstrating a way to clean up junk in these orbits.

Sierra Space announces plans to build a second Dream Chaser cargo spaceplane
With the first launch of Sierra Space’s first Dream Chaser reusable unmanned cargo mini-shuttle, Tenacity, now scheduled for May 2025, the company has announced that it is beginning work on a second cargo spaceplane, dubbed Reverence, along with a mission control center to operate its fleet in orbit.
Sierra Space spokesperson Alex Walker shared the new May 2025 estimate and said work on Reverence, also known as DC-102, will resume once the team returns to Colorado — but declined to clarify when that would happen. At that point, Walker said, it will likely be another 18 months before the second spaceplane is complete. In addition to the fleet of cargo-carrying craft, Sierra Space is also working on a crewed variant of the vessel, labeled the DC-200 series, and a national security DC-300 variant.
Company officials say each mini-shuttle is good for 15 flights, so having both vehicles gives the company a total of 30 flights to sell to various space station and orbital customers.
Selling to others outside NASA may be necessary, because Tenacity is four-plus years behind schedule. By the time it begins flying ISS will already be approaching retirement in only a few short years.
The company intends these new Dream Chaser projects to work in tandem with its LIFE inflatable modules, which are presently being developed as part of the Blue Origin-led Orbital Reef space station. And while much of work on the rest of that station appears moribund, it appears that Sierra is developing everything needed for its own space station. We should therefore not be surprised if Sierra decides to bid on NASA’s next space station funding round independent entirely of the Orbital Reef partnership.
It certainly is assembling all the pieces needed for a station, without any help from Blue Origin.

Giant dunes in a dune sea inside a Martian crater
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on July 17, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The white dot on the overview map above marks the location, inside a thirty-mile-wide dune sea, or erg, that sits in the center of the floor of 80-mile-wide Russell Crater.
That erg is interesting in that it appears the dunes get larger and larger as you move from the perimeter to its center. Thus, the dunes in the picture are called mega-dunes, about 200-feet-high. They dwarf the smaller dunes at the erg’s edge.
This picture was taken as part of a long term monitoring program to track the coming and going of seasonal dry ice frost on these dunes. It is summer when this picture was taken, so there is relatively little visible frost, though the bright blue areas in the color strip could possibly be the last remnants from winter. In winter, data suggests the entire surface of these dunes is covered by dry ice frost.
As the location is at 54 degrees south latitude, it likely sits at the northernmost edge of the southern dry ice mantle that in winter covers each of the Martian poles, down to about 60 degrees latitude.

NASA denies press reports that Sunita Williams on ISS has health issues
After the Daily Mail in the UK reported that it appeared that Sunita Williams on ISS appeared “gaunt” in recent pictures and might have health issues due to her unexpectedly long stay in space, NASA today issued a denial, stating unequivocally that she “is in good health.”
The pictures used to suggest she is “gaunt” are mostly based on the shape of her face, but this means nothing. Weightlessness shifts things about. The Daily Mail report used the analysis of those photos by a doctor in Seattle.
While the two have put on a positive front in their public comments and interviews, a recent photo tells a different story, according to Dr Vinay Gupta, a pulmonologist and veteran in Seattle. Dr Gupta told DailyMail.com: “What you’re seeing there in that picture is somebody that I think is experiencing the natural stresses of living at a very high altitude, even in a pressurized cabin, for extended periods. Her cheeks appear a bit sunken – and usually it happens when you’ve had sort of total body weight loss,” Dr Gupta added.
“I think what I can discern by her face and her cheeks being sunken in is that [she] has probably been at a significant [calorie] deficit for a while.”
As a general rule, it is considered to be unethical for a doctor to make any diagnosis from a distance based on press reports. Gupta might be right, but more likely he is basing these opinions on very incomplete data. In this case I would generally trust NASA’s denial, especially becauase Williams is a very experienced astronaut who has done previous long missions on ISS.

Vast signs astronaut agreement with Czech government
The space station startup Vast has announced it has now signed an agreement with the Czech government to possibly fly one of its astronauts to the company’s Haven space stations, either the smaller Haven-1 or the full size Haven-2 to follow.
Any future mission with Vast could see Aleš Svoboda, one of 12 reserve astronauts selected by the European Space Agency in November 2022, become the second Czech astronaut. Svoboda has been a focal point for the Czech government’s efforts to stimulate growth in the Czech space industry and inspire the country’s young people to pursue STEM careers, crystallized by the launch of the Czech Journey to Space project in June 2024.
In September 2024 the Czech government had signed a similar agreement with Axiom. Under that agreement, Svoboda would fly to ISS. This new deal opens the possibility he will fly elsewhere.
It is very possible the Czechs want to do both, and are covering their bets by signing both agreements. In either case, no mission dates have been set.

Next Starship/Superheavy test flight now targeting November 18th
SpaceX today announced its plan to fly the next and sixth orbital test flight of its Starship/Superheavy rocket on November 18th, less than two weeks from today.
The next Starship flight test aims to expand the envelope on ship and booster capabilities and get closer to bringing reuse of the entire system online. Objectives include the booster once again returning to the launch site for catch, reigniting a ship Raptor engine while in space, and testing a suite of heatshield experiments and maneuvering changes for ship reentry and descent over the Indian Ocean.
The success of the first catch attempt demonstrated the design feasibility while providing valuable data to continue improving hardware and software performance. Hardware upgrades for this flight add additional redundancy to booster propulsion systems, increase structural strength at key areas, and shorten the timeline to offload propellants from the booster following a successful catch. Mission designers also updated software controls and commit criteria for the booster’s launch and return.
As noted earlier, the FAA has made it clear that no new license is required since this flight plan is essentially the same as the fifth flight.

The resounding landslide victory by Donald Trump and the Republicans yesterday is going have enormous consequences across the entire federal government. As a space historian and journalist who has been following, studying, and reporting on space policy for decades, this essay will be my attempt to elucidate what that landslide will mean for NASA, its Artemis program, and the entire American aerospace industry.
The absurd cost of each SLS launch
The Artemis Program
Since 2011 I have said over and over that the government-designed and owned SLS, Orion, and later proposed Lunar Gateway space station were all badly conceived. They all cost too much and don’t do the job. Fitting them together to create a long term presence in space is difficult at best and mostly impractical. Their cost and cumbersome design has meant the program to get back to the Moon, as first proposed by George Bush Jr. in 2004, is now more than a decade behind schedule and many billions over budget. Worse, under the present program as currently contrived that manned lunar landing will likely be delayed five more years, at a minimum.
For example, at present SLS is underpowered. It can’t get astronauts to and from the Moon, as the Saturn-5 rocket did in the 1960s. For the first manned lunar landing mission, Artemis-4, SLS will simply launch four astronauts in Orion to lunar orbit, where Orion will rendezvous and dock with the lunar lander version of Starship. That Starship in turn will require refueling in Earth orbit, using a proposed fuel depot that has been filled by multiple earlier Starship launches.
Once Starship is docked to Orion the crew will transfer to Starship to get up and down from the Moon, and then return to Earth in Orion.

Ghana approves a government space policy
In a process that began in 2018, Ghana has finally approved a new government space policy that shifts bureaucratic control from a government agency not specifically focused on space to a new Ghana Space Agency.
Though Ghana officials repeatedly claim this is to encourage a commercial industry, all this policy decision has done is to create a new government agency to run things. It also appears that to make this change took years of negotiation among all the various government agencies involved, so that everyone could protect their own interests.
Don’t expect much from Ghana in the near future. All this policy does is concentrate power within its government.

FCC issues first deep space communications license to private asteroid mining company
The Federal Communications Commission (FCC) on October 18, 2024 issued the first deep space communications license to the private asteroid mining startup company Astroforge for its planned Odin mission to an asteroid.
Asteroid prospecting company AstroForge has been awarded the first-ever commercial license for operating and communicating with a spacecraft in deep space, ahead of its Odin mission that’s set to launch and rendezvous with a near-Earth asteroid in early 2025.
The license, granted by the U.S. Federal Communications Commission (FCC) on Oct. 18, pertains specifically to setting up a communication network with radio ground stations on Earth, to enable commands to be sent up to Odin and data to be transmitted back to Earth. In this case, deep space is defined by the International Telecommunications Union as being farther than 2 million kilometers (1.2 million miles) from Earth.
Other private companies have sent missions to the Moon, but this will be the first to go beyond. Odin will orbit and map the asteroid — not yet chosen — in advance of a larger AstroForge spacecraft, dubbed Vestri, that will land on the asteroid.

The first cubesat launched using wood for its side panelling
One piece of cargo carried by the cargo Dragon to ISS earlier this week is the first cubesat ever to use wood for its side panelling.
Made by researchers in Japan, the tiny satellite weighing just 900g is heading for the International Space Station on a SpaceX mission. It will then be released into orbit above the Earth. Named LignoSat, after the Latin word for wood, its panels have been built from a type of magnolia tree, using a traditional technique without screws or glue.
Researchers at Kyoto University who developed it hope it may be possible in the future to replace some metals used in space exploration with wood. “Wood is more durable in space than on Earth because there’s no water or oxygen that would rot or inflame it,” Kyoto University forest science professor Koji Murata told Reuters news agency. “Early 1900s airplanes were made of wood,” Prof Murata said. “A wooden satellite should be feasible, too.”
The satellite’s frame is still metal, but by using wood for its side panelling the engineers hope to test the feasibility of wood as a in-space construction material.

Jeff Daniels – Abraham Lincoln’s Gettysburg speech
An evening pause: On election day, I give you the most concise and poetic description of what America has always stood for, first spoken on November 19, 1863. On this day it will either signal “a new birth of freedom,” or a sad funeral speech to a nation that was dedicated to government of the people, by the people, for the people, and successfully proved it for almost 250 years.
November 5, 2024 Quick space links

- Another Chinese pseudo-company proposes another copycat New Shepard suborbital tourist spacecraft
There are a lot of these pseudo-companies popping up in China. Who knows how many are real.
- Cargo Dragon just launched will test using Draco thrusters to reboost ISS
This test will change the station’s telemetry almost not at all, but its goal is to eventually find multiple options for replacing this task presently done by Russian Progresses.
- Twin ESA satellites arrive in India for intergration into PSLV rocket
Launch is presentlhy scheduled for November 29, 2024.
- On this day in 2013 India launches its first interplanetary probe, the Mars Orbiter Mission or Mangalyaan
It operated in Mars orbit for about eight years.

Meandering channels on Mars
Click for original image.
Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 2, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The scientists describe this as “meandering channels,” which seems appropriate. The downhill grade here is to the southeast. In wider views these channels extend from the northwest to the southeast about 31 miles total (with this location near the center), with the total elevation loss about 3,000 feet.
Note the splash apron around the 4,500-foot-wide unnamed crater as well as how the largest channel seems to terminate suddenly at the crater. Though at first glance it appears this impact occurred after the channels, that some of the channels cut into that splash apron suggests otherwise.

Expect fewer and less violent protests should Trump win
No more American Kristallnachts
Based on recent events, I am willing to predict that we shall see much less violence than expected in the days after the election should Donald Trump win. And if those protests occur, they will mostly be concentrated in Democratic Party strongholds where the protesters feel reasonably confident they can get away with it.
I base this optimistic prediction on the trends we have been seeing. As I first noted in April 2024, the strength of these leftist protests has clearly lost steam in the last four years. While in 2020 the protests and looting and violence occurred almost everywhere, destroying many inner cities, in the last year those protests have mostly been confined to college campuses, and have resulted in relatively little damage in comparison.
The reasons have been two fold. First, the authorities, while still generally treating these protesters too gently, have still responded more aggressively. Violent protesters are now arrested. Some face prison terms. Faced with real consequences, this violent leftist protest movement can no longer get the same numbers to turn out.
Second, the protests and violence has declined because of the utter failure of these protests to work. If anything, the looting and destruction has convinced vast numbers of Americans to oppose the left and to now vote with even greater energy against the politicians who support it.
Thought trends have been obvious for months, recently we have had even more evidence that the protests and violence will be less should Trump win. And that evidence is striking.
