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.
"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
Cool image time! The picture to the right, cropped to post here, was taken on March 23, 2026 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
It shows the eastern interior rim of a 4.5-mile-wide crater, and was taken to find out if there has been any change to the gullies flowing down that 800 foot slope since the last high resolution image was taken in 2020.
Both pictures were taken in the spring, and both pictures not only don’t appear to show much change, both show the same white frost in exactly the same places. As no pictures have been taken at other times in the year, we do not know yet if this frost disappears as expected in summer.
In fact, until such images are taken and prove this white material disappears in the summer, we don’t even know for sure if it is indeed frost. We could instead be looking a some unusual form of white bedrock, though in my review of many MRO pictures such things are quite rare.

Artist rendering of Vast’s Haven-1 station, with a docked
Dragon capsule. Like Have Demo, it is being built using
company funds with no government support.
The space station startup Vast yesterday unveiled a new product line of high powered satellite buses, dubbed Vast Satellite, designed to support the expected boom in satellite construction.
With the launch of Vast Satellite, Vast is expanding beyond commercial space stations into high-volume spacecraft platforms designed for high-performance orbital missions. The first offering is a 15 kW-class satellite bus designed to support a wide array of power-intensive missions through flexible configurations.
Built around common in-house subsystems—including avionics, power, communications, propulsion, and flight software—Vast Satellite leverages technologies already developed for its Haven-1 space station, and validated through the successful Haven Demo mission in 2025. This shared architecture combined with Vast’s vertically integrated manufacturing model and advanced production capabilities is designed to support faster development timelines, lower costs, and increased mission reliability.
The company says it has already sold four buses to a confidential customer, with an option for 200 more. This sale occurred because Vast has proved itself with its policy of committing its own investment capital in designing, building, and flying demo missions. The Haven Demo was initially launched to test the subsystems to be used on the Haven-1 single module station the company hopes to fly next year on a three-year mission, during which four two-week manned crews will occupy it. That success allowed Vast to now diversify, using what it learned and proved on that demo to sell new products to other customers.
Similarly, its Haven-1 station, built on its own dime with no NASA funds, is intended to prove its capability as a space station provider. If successful, it is certain at that point to attract customers, including NASA.
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.
“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.

The Sri Lanka government has now established a committee whose task will be to formulate the country’s first space policy.
The Cabinet of Ministers has approved a resolution presented by the Minister of Science and Technology to appoint an expert committee tasked with formulating Sri Lanka’s first National Space Policy. According to the government, space technology has become a critical driver of national development, delivering benefits across disaster management, communication, security, environmental monitoring, and economic innovation.
Sri Lanka is a signatory to the Outer Space Treaty, so any policy it establishes has to fall under its rules and limitations. This op-ed today in one of the nation’s major media outlets provides a very detailed overview of the issues. It seems the country has a lot of options, most of which revolve around attracting already established aerospace companies to build there.
SpaceX in the early morning hours today successfully placed another 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.
The first stage completed its second flight, landing on a drone ship in the Pacific.
The leaders in the 2026 launch race:
58 SpaceX
28 China
8 Russia
6 Rocket Lab
For the third straight year SpaceX leads the entire world combined in total launches, 58 to 50.

"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke
The asteroid probe Psyche on May 15, 2026 successfully completed its last fly-by of Mars, sending the spacecraft on its way to the asteroid Psyche, with a planned arrival in 2029.
The image to the right, cropped, rotated, and, reduced to post here, was the highest resolution image released by the science team of the Martian south polar icecap.
The image scale is around 0.7 miles per pixel (1.14 kilometers per pixel). The cap itself extends across more than 430 miles (700 kilometers). The image was acquired with Imager A on May 15, 2026, at about 1:53 p.m. PDT.
The white material is the perennial dry ice cap overlaying a water ice cap of larger size.
NASA also released several other images taken during the fly-by, including a close-up of the 290-mile-wide Huygens Crater, located in the Martian southern cratered highlands.
The pictures reveal no significant science, but they prove once again that Psyche’s cameras are working and the spacecraft is pointing accurately.

A worker at SpaceX’s Boca Chica facility died on May 15, 2026 after falling eight feet from a scaffold.
A 25-year-old man died after falling 8 feet from a scaffold at a SpaceX facility, according to Justice of the Peace Mary Esther Sorola.
The Cameron County Sheriff’s Office first confirmed the death and said it happened on Friday, May 15. The man has been identified as Jose Bautista from Donna. Sorola said Bautista was taken to Valley Regional Medical Center by a SpaceX ambulance. A preliminary autopsy report says he suffered blunt force trauma from the fall; he died at the hospital.
The Wall Street Journal calls the victim a “contractor”, not a SpaceX employee.
As is routine for such incidents, the Occupational Safety and Health Administration (OSHA) has begun an investigation.
This incident is likely unrelated to the more recent short delays in the 12th Starship/Superheavy test flight, as it occurred prior to those delays. It is also puzzling for someone to die from so short a fall. Either the height is incorrect, or some other factors must have been at play.

UPDATE: One day after its announcement below, SpaceX announced another one day delay. The 12th Starship/Superheavy launch is now targeting May 21, 2026, with a launch window beginning at 5:30 pm (Central).

SpaceX earlier today announced a revised launch date for the 12th Starship/Superheavy orbital test flight, delayed one day from May 19, 2026 to May 20, 2026, with a launch window opening at 5:30 pm (Central).
No reason was given. I suspect weather might have played a factor, but it is also possible that some technical issues required a short delay.
Either way, the link to the X live feed will be posted here once it goes live. I will also embed it on Behind the Black once it goes live.
Working with the American Institute of Aeronautics and Astronautics (AIAA), the American satellite companies building large orbital constellations — SpaceX, Amazon, Iridium, and Eutelsat — have now released a joint reference guide for building and operating their satellites, dubbed “Satellite Orbital Safety Best Practices 3.0.”
- Emphasizes the design phase for improved orbital safety
- Stresses pre-launch coordination and collision avoidance analysis, especially near crewed vehicles, mitigating hazards during post-launch identification and cataloging of new orbital objects
- Provides guidance on data sharing across design and operations emphasizing the critical importance of sharing and screening high quality ephemeris with covariance from deployment through disposal
- Includes an Appendix with data exchange recommendations to mitigate conjunctions
The companies have apparently decided they needed to get together to make sure they were not stepping on each other’s toes. I would expect other companies to soon join this cooperative effort, as it is in no one’s interest to have satellites colliding in orbit.
