SpaceX this morning 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 22nd flight, landing on a drone ship in the Pacific.
The leaders in the 2026 launch race:
64 SpaceX
30 China
8 Russia
7 Rocket Lab
For the third straight year SpaceX leads the entire world combined in total launches, 64 to 54.

The first segment below is definitely worth listening to, because my discussion with John Batchelor about the Blue Origin explosion yesterday demonstrated quite clearly the difficulty of most people to understand that the NASA Moon program is no longer the only game in town. John kept asking if SpaceX can continue our Moon program, and I kept trying to explain to him that it not only could, its private effort was the American space effort, and that effort will carry NASA’s increasingly irrelevant Artemis program along with it. He couldn’t get it. As far as he was concerned, the only program that mattered was the government program of NASA’s, and if that program is in trouble he worries we have nothing at all.

ULA this evening successfully placed 29 more Leo satellites into orbit for Amazon, its Atlas-5 rocket lifting off from Cape Canaveral Space Force Station in Florida.
ULA is in the process of retiring the Atlas-5 rocket. It now has only seven Atlas-5 rockets left in stock, with one reserved for Leo launches and six for Boeing’s Starliner manned capsule (though there is a good chance some if not all of the Starliner launches will be switched to other payloads). Because its Vulcan rocket, intended to replace Atlas-5, is presently grounded, the company appears to be accelerating Atlas-5 launches, with the last few launches space only about a month apart.
With this launch, Amazon now has 331 Leo satellites in orbit, out of the 1,616 it needs to launch by July to meet its FCC license requirement. It is not going to meet that requirement, because two of the five rockets it contracted for launches are presently grounded (ULA’s Vulcan and Blue Origin’s New Glenn), and only one launch is presently scheduled before July, by Arianespace’s Ariane-6. Furthermore, ULA has only one more Atlas-5 scheduled for Leo, and the ten launches Amazon had purchased from SpaceX are not scheduled. For these reasons, Amazon has asked for a time extension, which the FCC is presently considering.
As this was only the fourth launch by ULA in 2026, the leader board for the 2026 launch race remains unchanged:
63 SpaceX
30 China
8 Russia
7 Rocket Lab
For the third straight year SpaceX leads the entire world combined in total launches, 63 to 54.
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 publicly traded rocket/lunar lander company Firefly yesterday announced a new public offering of stock, totalling more than 12 million shares, with the goal of raising more than a half billion for “general corporate purposes.”
Firefly Aerospace (Nasdaq: FLY), a market leading space and defense technology company, today announced the pricing of its public offering of 4,000,000 shares of its common stock and 8,000,000 shares of common stock by certain selling stockholders (the “Offering”) at a public offering price of $48.00 per share. In addition, the selling stockholders have granted the underwriters a 30-day option to purchase up to an additional 1,800,000 shares of common stock at the public offering price, less underwriting discounts and commissions. The Offering is expected to close on June 1, 2026, subject to customary closing conditions.
Firefly intends to use the net proceeds from the Offering for general corporate purposes, including to support growth of core business and recently awarded programs and initiatives. Firefly will not receive any of the proceeds from the sale of shares by the selling stockholders.

Simple math says this offering hopes to raise $576 million dollars, assuming the $48 per share price holds.
The graph to the right shows the full price history of Firefly’s stock since the initial public offering in 2025. After an initial high around $60, the stock sagged to around $20, and only has recovered back into the $40 to $50 range in the past few months. It appears therefore that the company has well timed this new offering.

By comparing 20 different Curiosity drill samples taken during the rover’s fourteen years on Mars, scientists have detected hard evidence that the climate in Gale Crater was distinctly different at different elevations, for long periods.
This study shows that hematite can also be a marker of climate changes based on its crystallite sizes and structures, which change under different temperatures. The scientists found that hematite crystallites from higher elevations in Gale Crater were less than 10 nanometers in size, while crystallites from lower locations were generally larger, reaching up to 65 nanometers. These findings aligned with the observations that samples from higher elevations contained both hematite and goethite, while lower elevation samples lacked goethite.
They concluded that, under warmer conditions when the pH of water is neutral or slightly alkaline, goethite can transform into hematite. These warmer conditions also favored an increase in hematite crystallite size in the deeper layers of Gale Crater through a process known as Ostwald ripening, in which smaller crystallites dissolve and contribute to the growth of larger ones. “This can tell you that the top layers were colder and didn’t have enough water, or the water presence was relatively short-lived, so the crystallites didn’t have sufficient time and conditions to grow in size,” said Peretyazhko. “But the lower layers had longstanding warm water that allowed those crystallites to grow.”
The white dots on the map to the right shows the location of the drill samples used, taken along Curiosity’s travels as it climbed Mount Sharp. Overall Curiosity has climbed about 2,500 feet, so the differences found the samples mark the past climate differences between the crater floor and the mountain’s foothills. According to this data, the crater floor had long-standing water in some form, exceeding millions of years. At higher altitudes there was less and less, and it was there for increasingly shorter periods.
As the press release notes, “A unique highlight of this study is that the data comes from Martian samples, rather than from theoretical modeling.” Similar conclusions from earlier Curiosity data required Earth proxies and computer modeling. This result is from hard data from Mars.
Hanbit-Nano less than five seconds after launch and
just prior to its failure in December 2025.
The South Korean rocket startup Innospace has signed a deal with the American company Ensemble Commercial Services to help obtain satellite contracts and manage the integration and deployment of these payloads.
This marks INNOSPACE’s second launch service distribution agreement in the U.S., following its agreement signed in August last year with Texas-based Arrow Science and Technology, LLC. By securing multiple local partners in the U.S., INNOSPACE plans to enhance customer accessibility in the North American market and accelerate its efforts to identify satellite launch demand and expand sales activities.
Under the agreement, Ensemble will identify potential customers in the U.S., including satellite companies, space startups and research institutions, and connect them with launch service opportunities offered by INNOSPACE for small satellites. Ensemble will also provide regular market updates on the U.S. satellite industry, launch demand trends and potential customer activities, supporting INNOSPACE’s sales activities in the U.S. market.
…With this agreement, INNOSPACE has now secured launch service distribution partners across nine companies in seven countries, including Taiwan, Japan, Italy, the Netherlands, the U.S., Germany and the United Kingdom.
Innospace has made one failed attempt in December 2025 to launch its Hanbit-Nano rocket. It hopes to try again in the third quarter of this year.

ASU, apparently one of many universities filled
with people now hostile to America
According to a just completed House investigation, hundreds academics and universities have routinely violated the law by taking NASA funding for their research but then working hand-in-glove with Chinese individuals or institutions.
A House investigation has identified hundreds of scientific publications in which NASA-funded U.S. researchers appear to have conducted joint work with Chinese institutions, potential violations of a federal law that has barred such collaboration for more than a decade.
The report, released on Wednesday by the House Select Committee on the Chinese Communist Party, also found that, in several instances, some of that research involved collaboration between National Aeronautics and Space Administration (NASA) scientists and institutions that are part of “China’s defense research and industrial base.”
You can read the full report here [pdf]. Among its numerous findings for example it notes that Arizona State University and Stanford University both filed false certifications, stating that they were not working with Chinese individuals, agencies, or institutes, even though their later published papers blandly listed such individuals, agencies, and institutes. The report lists numerous other similar examples.
During Trump’s first administration the Justice Department made a concerted effort to enforce this law. Under Biden that effort ended (with many prosecutions abandoned), to be replaced with a zealous effort to ignore it, an effort enthusiastically supported by the partisan leftist academic community. This new report essential outlines the violations that began during the Biden era.
China is aggressively working on all levels to steal technology from the west. Sadly, it is more and more aided by America’s university system and the administrators, professors, and researchers based there, a large majority of whom are now outright hostile to our country and wish to sabotage it.
During a static fire test of the first stage tonight in preparation for the next launch scheduled for June 4), Blue Origin’s New Glenn rocket exploded just as the test began, destroying the first stage and much of the only launchpad the company has to launch this rocket.
The link above is cued to just before the explosion, shown in a screen capture to the right. BtB’s stringer Jay just sent me a link to a different video view, from farther away but is in some ways as spectacular. According to Blue Origin’s statement, all workers are accounted for, so fortunately there were no fatalities.
The rocket was to launch 48 Amazon Leo satellites. As those satellites were not on the rocket during this test, they are safe and can be launched elsewhere.
The failure will likely prevent any further New Glenn launches by Blue Origin for at least three to six months. Not only does the company have to determine and fix the cause of the failure, it will need to rebuild the launchpad. At best I expect the company will at best manage one test launch before the end of the year.
As for Amazon, this puts it in a big bind. It has only 302 satellites in orbit, but is required to have launched 1,616 by July, according to its FCC license. It has requested a waiver but the FCC has not yet responded. At the moment of the four companies it has hired to launch the satellites, two are now grounded:
There is no timeline for when Vulcan and New Glenn will fly again. Arianespace hopes to do four to six more launches in ’26, but only one is an Amazon Leo launch, in June. ULA has six additional Atlas-5 rockets in stock, purchased by Boeing to launch its Starliner capsule to ISS. It is very possible a deal could be arranged with Boeing to switch some of those flights to Leo, since at present there are no plans to launch Starliner in the near future.
All in all, Amazon’s only remaining option is SpaceX. Of the ten unflown launches in the SpaceX contract, none are as yet scheduled. It is now likely Amazon will negotiate a deal with SpaceX to accelerate that schedule. While SpaceX’s own launch manifest is quite crowded (launching its own Starlink constellation), making such a deal difficult, the company has also demonstrated its willingness to help competitors. It launched OneWeb satellites when that company’s deal with the Russians fell through. And it quickly launched those first three Leo missions, faster than anyone else.
This also will impact NASA’s just announced unmanned lunar lander program. One mission planned for this year, Blue Origin’s Blue Moon Mark-1 unmanned lander, was scheduled to launch on a New Glenn. In addition, a second New Glenn was set to launch NASA’s Viper rover next year. Neither will happen as scheduled.
An evening pause: Performed with real joy, on the streets of New Orleans.
