- Gilmour Space once again delays first launch of its Eris rocket
The new target launch date is July 16th.
- On this day in 1985 Europe’s Giotto probe was launched to visit Halley’s Comet
The fly-by occurred on year later.
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
EPA employees who publicly signed letter opposing Trump’s agenda have now been put on leave
Trump in charge
They apparently forgot who the American people elected and who is thus the boss! The 170 EPA employees who publicly signed a letter this week announcing their opposition to Trump’s policies at EPA have now all been put on leave, with the expectation that they will eventually lose their jobs as well.
Staffers at the Environmental Protection Agency who signed a letter of dissent against President Donald Trump have been placed on leave, reports The Hill. “The Environmental Protection Agency has a zero-tolerance policy for career bureaucrats unlawfully undermining, sabotaging, and undercutting the administration’s agenda as voted for by the great people of this country last November,” EPA spokeswoman Brigit Hirsch said in a written statement.
The letter, posted on June 30, 2025, made it very clear in its opening paragraph that these employees were willing to defy orders and sabotage the Trump administration.

Russia launches Progress freighter to ISS
Russia today (July 4th in Kazakhstan) successfully launched a new Progress freighter to ISS, its Soyuz-2 rocket lifting off from the Baikonur spaceport in Kazakhstan.
The freighter will dock to ISS in two days, bringing with it almost three tons of cargo and more than a half done of hardware and equipment. Expect NASA to order its astronauts to shut the hatch between the American and Russian sections of ISS due its fear that a docking to the Zvezda module could cause a catastrophic failure because of the stress fractures in that module’s hull. That docking will however not be directly to Zvezda, but to the Poisk module that is itself docked to Zvezda.
The lower stages and strap-on boosters crashed inside Kazakhstan in the normal drop zones that Russia has used for decades.
The leaders in the 2025 launch race:
84 SpaceX
36 China
10 Rocket Lab
8 Russia
SpaceX still leads the rest of the world in successful launches, 84 to 63.
Russia’s launch pace this year is its lowest pace in decades. At this rate Russia might only get about 15-17 launches off in 2025, a count more comparable to what it did in the very early 1960s. This decline can be directly linked to the Russian invasion of the Ukraine. That invasion caused Russia to lose billions in contracts in the international launch market. And it continues to prevent Russia from winning any new international contracts as well. Except for its government launches (which are limited due to government cash shortages), the only other missions Russia flies are those to ISS, and those number about four per year.

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.

Mars is not dry!
I once again feel compelled to rant against the shallow ignorance of too many people in both the journalism field as well as academia about the most recent data we now have of Mars. Two articles today once again show this ignorance, assuming blandly that Mars is a dry planet with little water on it anywhere, when orbital data over the past decade has unequivocally shown that — except for its equatorial regions — the planet is covered with a LOT of near-surface ice.
The headlines make this ignorance quite clear:
- University of Chicago: Was Mars doomed to be a desert? Study proposes new explanation
- Space.com: The secret of why Mars grew cold and dry may be locked away in its rocks
In both cases, the articles assume that the data obtained from rovers and landers in the dry Martian tropics applies to the entire planet. It does not. This evidence of a dry planet carries a bias that comes from the decision by the planetary community as well as NASA to send every rover to that dry equatorial region. Only one lander, Phoenix, has ever been successfully dropped far from the Martian equator, and it was purposely sent to a very high latitude, where it proved there was ice present just below the surface.
Orbital data in the past decade from both Mars Reconnaissance Orbiter and Mars Express has clearly shown that there is a lot of near surface ice on Mars, as shown by the map above. In the mid-latitudes the terrain is dominated by glaciers, as this is the region where the vast ice sheets in the high latitudes begin to fade away.
Only the equatorial region, indicated by the white lines on the map, is dry and barren. And yet, even here, orbital data has detected evidence that suggests underground ice still exists.
It seems to me that journalists and academic PR departments should know these facts, and include them in any reports about the dry nature of Mars’ equatorial regions.
European capsule startup wins $15 million grant
A Luxembourg-based startup aimed at building orbiting recoverable capsules for cargo as well as in-space manufacturing has won a $14.7 million grant from the European Innovation Council as part of its European Innovation Council Accelerator program to encourage development in Europe’s private commercial space sector.
The company, Space Cargo Unlimited, will use the money to develop what it calls its “BentoBox in-orbit testing and manufacturing platform.” It is also partnering with well-established European company Thales-Alenia, with the BentoBox development based on previous work done for the European Space Agency’s (ESA) Space Rider demonstrator project.
The overall nature of this grant and work illustrates Europe’s aggressive shift in the past two years from the government model, where ESA designed and owned everything, to the capitalism model, where the government is merely the customer, buying what it needs from the private sector. The government-built Space Rider, which was intended to be a re-usable space plane similar to the X-37B, has never flown. Now, its technology is being repurposed by private European companies for their own spacecraft with the intention of making profits. And this Bentobox project is a prime example.
The inaugural flight of the BentoBox platform as a standalone system using the ATMOS inflatable heatshield is expected in the fourth quarter of 2025. As of a late 2024 update, Space Cargo Unlimited had already secured bookings for 80% of the inaugural flight, and 50% and 40% of the second and third flights, respectively.
Note too that Space Cargo is a European competitor with Varda in the U.S. It appears Europe wants some of this business for itself.

China launches technology test satellite
China today successfully launched a technology test satellite, its Long March 4C rocket lifting off from its Xichang spaceport in southwest China.
As is usual for China’s state-run press, little information about the satellite was released. The most information any article provided was this:
The satellite, designed and built by the Innovation Academy for Microsatellites under the Chinese Academy of Sciences in Shanghai, will measure and survey space environmental elements and test new technologies.
Nor did that state-run press provide any information about where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.
The leaders in the 2025 launch race:
84 SpaceX
36 China
10 Rocket Lab
7 Russia
SpaceX still leads the rest of the world in successful launches, 84 to 62.
Two more former SpaceX employees sue the company for harassment and discrimination
SpaceX employees cheering the first chopstick capture of
Superheavy, October 13, 2025. Click for video.
Two new articles today outline two different new lawsuits against SpaceX by former employees, with both claiming harassment and discrimination as reasons for their firing.
- Black SpaceX technician says in lawsuit he was fired for being late while white workers’ tardiness was ignored
- Former SpaceX manager alleges harassment, retaliation, and security violations in lawsuit
In the first case, the former employee, L’Tavious Rice, claims that he “was fired for being late to work while caring for his young daughter as she recuperated from a heart transplant, while his white colleagues were given a pass for their own “consistent tardiness and absences.” The lawsuit also claims the SpaceX human resources department was retaliating against him because he testified about another employee’s misbehavior in another unrelated case.
In the second case, the former employee, Jenna Shumway, claims she was passed over for promotion, and the man who got the job “waged a campaign of harassment against her, which included stripping her of her responsibilities over a period of months and ultimately leading to her termination in October 2024.” She also claims this “harassment extended to other female employees, too.”
I have no idea whether these claims are true or not. I tend to be skeptical, because of the overall make-up of SpaceX’s entire work-force. The image to the right, a screen capture from the company’s broadcast during the fifth flight of Starship/Superheavy on October 13, 2024 and taken mere seconds after the first successful capture of Superheavy. illustrates this. The SpaceX work-force is young, and typical of engineering, more male than female. At the same time it has many long time female employees, including the company’s president and chief operating officer, Gwynne Shotwell.
We must not also dismiss the possibility of political motives in these lawsuits. In the past three years the left has made it clear it is out to get Elon Musk, and that campaign has included vandalism, regulatory sabotage, and numerous other environment lawsuits by leftist activist groups whose funding is political.
At the same time, it is very possible that these two former employees have legitimate beefs. We shall have to see how both cases play out in the courts.

- Another Chinese pseudo-company unveils its proposed Falcon 9 copycat rocket
It calls itself New Space, or Xiamen in Chinese. As far as I can tell, it makes great computer graphics, but nothing else.
- Vast touts the beginning of thermal vacuum testing of what it calls its Haven Demo
It is unclear if this Haven Demo is actually the Haven-1 module being built at this time for launch next year.
- ArianeGroup touts completion of static fire tests of its Prometheus rocket engine
The engine will first fly on a suborbital test flight of Europe’s Themis demonstrator, but later will be the main engine used on Maiaspace’s Maia smallsat rocket.
- New geometry discovery could stop lunar landers from falling over
This is the stupid-story-of-the-day. A lot of news outlets have picked it up, but it only takes a nano-second of thought to realize this is hardly a solution to keep lunar landers from tipping over. It is far too complicated a solution to what is really a very simple problem: extend the legs out more and keep the center of gravity low.
July 1, 2025 Zimmerman/Space Show appearance
My two hour appearance yesterday on the Space Show with David Livingston is now available as a podcast. You can find here.
A number of members of the Space Show’s advisory board joined the Zoom feed to raise questions and add their perspective, which made it for me at least a truly fascinating two hours. Lots of discussion about Starship, about Artemis, and about the desperate need for Americans to stop emoting and begin to discuss these issues calmly and rationally. This mature nature of the discussion made this show is very much worthwhile listening to.
New data: the ozone hole occurs mostly because of the sunspot cycle and cosmic rays, not CFC pollution
The uncertainty of science: A science paper released yesterday suggests that the ozone hole over Antarctica that scientists have been tracking for almost a half century is caused mostly by the solar cycle and the accompanying fluctuations in cosmic rays hitting the upper atmosphere, not the release of chlorofluorocarbons (CFCs) that used to be used in aerosol spray cans.
The graph to the right, from figure 2 of the paper, illustrates the data. The red line is the ozone hole fluctuations predicted by the paper’s model, labeled “CRE Theory”, based on the increase of cosmic ray radiation during solar minimum. The blue, black, and green lines indicate the actual fluctuations of ozone and temperature in the lower stratosphere where the ozone layer exists. As you can see, the model and actual fluctuations match quite closely. From the paper’s abstract:
