Rocket Lab buys Iridium

3:39 pm

In a blockbuster deal today, Rocket Lab acquired the satellite company Iridium and all its satellite constellation assets.

Rocket Lab will acquire all the outstanding shares of Iridium common stock for $54 per share in a cash and stock transaction. This represents an enterprise value for Iridium of approximately $8.0 billion.

The acquisition … merges Rocket Lab’s leading launch capabilities and satellite manufacturing with Iridium’s global satellite communications network, spectrum, and 500-plus strong partner ecosystem to create a competitive, vertically-integrated space company that designs, builds, launches, and operates its own constellations, delivering critical communications capability to millions of users worldwide.

The transaction will give Rocket Lab an immediate foothold in space-based applications, including both proprietary and standards-based satellite Internet of Things (IoT) and direct-to-device (D2D), PNT (GPS-capability), and critical safety-of-life services, creating a formidable challenger in the global telecom market.

This deal continues Rocket Lab’s aggressive effort in the last few years to diversify its capabilities beyond simply launching rockets. It has successfully demonstrated its ability to build satellites and even interplanetary probes. This merger immediately gives the company the spectrum and communications constellation that already has 2.5 million subscribers, with the ability to enhance and expand that constellation using its launch and satellite capabilities. With the introduction of its larger Neutron rocket next year, Rocket Lab will be well positioned to compete directly with all the other communications constellations, and to do it at a lower cost.

The deal also strengthens the company’s vertical integration. As the press release notes, it “creates an end-to-end space company spanning launch, spacecraft, spectrum, and on-orbit communications services through a proprietary network. Expected to eliminate third-party launch costs for constellation deployment and replenishment and captures launch margin internally while guaranteeing orbital access as launch capacity tightens, ensuring continuity of service to customers.”

Not surprisingly, the value of Rocket Lab’s stock today has leaped upward, rising from a closing price on Friday of around $85 to over $100 today (late Monday).

The industry trend across the board now is vertical integration, begun by SpaceX. It just pays to have the rocket company own the satellite constellation. Such a partnership lowers cost, and gives the company great flexibility and control. Expect more satellite constellations to team up with other rocket companies, especially the startups like Stoke Space and Relativity that are building reusable rockets.

We’re all gonna die! Seismologists model the San Andreas fault, and find it about to blow!

9:37 am

Chicken Little rules!
Chicken Little rules!

According to computer simulations based on known but very limited earthquake data during the past 1,000 years, scientists now claim that the San Andreas fault in California is now “critically stressed,” suggesting a big quake is coming soon.

You can read their paper here. The news article at the first link above is typical of most mainstream reports, very much focused on expressing certain doom based on the certainty of this research:

The volatile seismic zone along the roughly 750-mile (1,200-km) San Andreas Fault and the smaller San Jacinto Fault are now “critically stressed” – reaching a 1,000-year high level of pressure – increasing the likelihood of a big earthquake hitting the US West Coast.

Using physics-based modeling and 1,000 years of earthquake data, Earth scientists at the University of Hawaiʻi at Mānoa demonstrated how the build-up of stress throughout these two fault systems and at the juncture of the Cajon Pass is at an all-time high.

The “1,000 years of earthquake data” however is extremely limited, with only the last 100 years reasonably covered. That sparse data is then used to create computer models and simulations, from which these Chicken Little conclusions are drawn.

In other words, garbage in, garbage out.

Without doubt a large quake along the San Andreas fault is eventually going to happen. In fact, scientists have been making this same exact prediction now for almost a half century. That no such quake has happened doesn’t make the prediction false, but the endless predictions of doom by the seismology community for a half century has made them sound increasingly like the little boy who cried wolf. They simply don’t have sufficient knowledge to predict when the quake will happen, but their endless cries of doom has blunted the impact of their words.

Meanwhile, the uncertainty and limitations of their knowledge are too often ignored by the press. To this press: “They are SCIENTISTS, so they KNOW!”

Hayabusa-2 to fly past asteroid July 5, 2026

9:13 am

samples from the surface in 2019. Arrow indicates planned touchdown
site.

Despite having only one working ion engine, Japan’s Hayabusa-2 asteroid probe will do a fast and extremely close fly-by of the asteroid Torifune on July 5, 2026.

The flyby will see Hayabusa2 get within 1 to 10 kilometers (0.62 to 6.2 miles) of Torifune, using its instrument suite to study the roughly 450-meter-wide (1,476 feet) asteroid as it whizzes past at 5.3 kilometers per second (3.3 miles per second).

Not much is known about Torifune, so a fly-by this close carries risk. In addition, three of Hayabusa’s four ion engines no longer work, and the fourth is starting to degrade.

If successful, however, the fly-by will not only tell us something more about Torifune, it will increase the chances Hayabusa-2 can reach asteroid 1998 KY26 in 2031. That asteroid is small, only about 35 feet across. The plan would be for Hayabusa- to fly in formation for a period, and even attempt a touch down.

NASA asks industry for proposals for building lunar base infrastructure

8:57 am

NASA today issued a request for feedback from the private sector for building its Moon Base, including the infrastructure for providing “surface power, in-situ resource utilization, [and] advanced manufacturing.”

The solicitation focuses on five technologies that NASA considers necessary but insufficiently developed at this point, some of which it also considers necessary for exploring and colonizing the entire solar system.

  • Solar power generation, including power management and distribution, and energy storage.
  • Radioisotope power, for use by operating spacecraft systems in the solar system’s “darkest, dustiest, and most remote places”.
  • In-situ resource utilization, including using lunar materials to produce fuel, water, and oxygen.
  • In-space advanced manufacturing for producing “essential tools and materials” on the Moon and Mars.
  • Innovative nanomaterials, for use in spacecraft and instruments in order to reduce their weight and size at launch.

The announcement notes that NASA is requesting input from industry, hoping it can “identify any areas of ambiguity, or concerns.” The agency will then revise accordingly.

This solicitation is another example of NASA administrator Jared Isaacman’s push to rationalize the entire Artemis program, to take seriously the real requirements for building a Moon base. Previously NASA made noises along these lines, but management did not do the proper due diligence to figure out what needs to get built in order to actually make a Moon base happen.

First unmanned test of India’s manned Gaganyaan capsule possibly delayed until late ’27

9:11 am

In a presentation yesterday, the head of India’s space agency ISRO V Narayanan indicated that the first unmanned test flight of its manned Gaganyaan capsule might be delayed until the third quarter of 2027.

That test flight was originally targeting a March 2026 launch — part of a series of three unmanned test flights before the manned flight in early 2027 — but March came and went and nothing happened, nor did ISRO explain the lack of any action.

In indicating the possible delay, Narayanan also noted that the agency was looking at a launch before the end of this year. A delay until late ’27 — more than a year — however would suggest a significant issue. It would also mean the manned flight could not occur until 2028, at the earliest.

When Gaganyaan was first proposed in 2018, the goal was to have the first orbital flight in 2022. Since then the program has experienced endless delays and postponements. This new announcement, with no explanation, fits ISRO’s recent pattern of secrecy. No specific reasons for this year’s delays have ever been offered. Meanwhile, the agency has refused to outline for more than two years the specific causes of the two PSLV rocket failures of its third stage, both of which occurred at almost the exact same time in launch.

The secrecy suggests a cultural problem at ISRO, even more serious than a technical one. It implies an unwillingness to deal with error, thus resulting in repeated failures.

Tiny polygon ridges on Mars

9:19 am

Tiny polygon ridges on Mars
Click for original image.

Cool image time! The picture to the right, cropped and reduced slightly to post here, was taken on June 21, 2026 by the high resolution camera on the Mars rover Curiosity. It looks down to provide a close-up of the ground the rover is presently parked over, a surface covered with thousands of these tiny polygon ridges, all of which appear less than three inches across.

For a wider view and the overall context, see my post from June 24, 2026. While from a distance the ground at this point looked smoother than anything the rover has seen in more than five years since it entered the foothills of Mount Sharp, once it got close it discovered the ground was completely covered with these small polygons.

The picture to the right is part of a close-up mosaic of these polygons the science team is gathering using the high resolution camera.

The geology here is certainly puzzling. Polygon cracks are not unusual on both Earth and Mars, in places where the ground was once wet and then dried. In drying the material shrinks, producing polygon-configured cracks. On Earth those cracks often fill later with material that is more resistant, such as lava, which remains to form ridges when the surrounding dirt erodes away. Whether this was the process here on Mars however is not known. For one thing, why are these polygons so small? And why so uniform in size?

SpaceX’s proposed cloud constellation of a million satellites named “Starmind”

8:54 am

Elon Musk has confirmed that SpaceX has named its proposed constellation of a million data computing satellites will be dubbed “Starmind”, following its pattern in recent years of naming every new project in a similar manner.

After Starship, Musk has named every project a variation thereof. We have had Starlink, Starshield, Starbase, Starfactory, Starfall, and now Starmind. It is also building natural gas pipeline to supply methane to Boca Chica that it has dubbed Starpipe.

The company hopes to launch the first Starmind satellites on Starship early in 2027.

Firefly buys the AI navigation technology used on its Blue Ghost lunar landing

8:45 am

Blue Ghost’s shadow on the Moon, with the Earth in the background,
after its 2025 touchdown.

Firefly has now acquired Space-ng, the company that makes the AI navigation technology and software that Firefly used on its successful Blue Ghost lunar landing in 2025.

Space-ng’s vision navigation software was utilized during Firefly’s historic Blue Ghost Mission 1 to determine position and attitude, detect hazardous lunar terrain, and autonomously redirect Blue Ghost in real-time, enabling a safe, precise touchdown within the Moon’s Mare Crisium.

…In addition to vision navigation software, Space-ng brings high-resolution spacecraft cameras and AI compute hardware to enable advanced space domain awareness, onboard optical navigation, rendezvous and proximity operations, and docking without requiring GPS or GNSS. Firefly plans to integrate Space-ng’s technologies across its fleet of lunar landers and orbital vehicles to support its growing mission manifest, including three additional lunar missions under NASA’s Commercial Lunar Payload Services initiative, another lunar mission supporting NASA MoonFall, and a space domain awareness mission for the Defense Innovation Unit.

Of all the recent attempts by commercial companies to land on the Moon, Firefly is the only one to have a complete success. While Space-ng’s technology worked perfectly to guide Blue Ghost to a safe touch down, the guidance technology used by Intuitive Machines (twice), Ispace (twice), Beresheet, and the first Vikram lander for India all failed close to landing. No wonder Firefly decided to buy it.

Musk’s employee stock options made them millions; Bezos’s employee options were worthless

8:31 am

According to a very intriguing article at Business Insider today, the stock options offered to employees at SpaceX and Blue Origin were starkly different, with SpaceX’s options making millions for its workers while Blue Origin’s were essentially worthless.

Three ex-employees of Jeff Bezos’ rocket maker Blue Origin told Business Insider that the company’s unusual approach to equity left them with stock options that are essentially worthless.

Meanwhile, they’ve watched SpaceX’s dizzying rise to a $2 trillion-plus valuation provide a massive windfall for early hires — from engineers to welders to cafeteria workers — who received stock options during their time at Elon Musk’s company.

Blue Origin’s options were written so that they only could be cashed in if the company went public within ten years. As Bezos has shown zero interest in going public — which would take away his full ownership and control of the company — those options have been steadily expiring as they reach their ten year due date.

At SpaceX however the employee stock options could always be cashed in, even before the company went public. Employees, both current and former, were allowed to sell their stock back to SpaceX or to its investors in private liquidity events that usually occurred twice each year. After the IPO they could now sell the stock on the open market, at the going rate.

The difference is possibly one additional reason the accomplishments of the two companies have been so starkly dissimilar/ SpaceX made sure its employees got a pay off for the long hours it demanded. Blue Origin did not.

Astronomers: We might be experiencing a shower of comets from the distant Oort cloud due to a close pass of another star 2.5 million years ago

1:18 pm

The uncertainty of science: Using computer models and the somewhat sparse data about the distant Oort cloud on the outer fringes of our solar system (from 2,000 to 200,000 astronomical units [au] away) and combining that with the data from the Gaia space telescope that mapped precisely the motions and distances of billions of Milky Way stars, astronomers now posit that the close pass of another star about 2.5 million years ago perturbed the Oort cloud and thus produced the shower of comets that humanity has been experiencing for the last few thousand years.

HD 7977 is a still nearby Sun-like star in the constellation Cassiopeia whose close passage was discovered by the Gaia mission. Approximately 2.5 million years ago, the orbits of the Sun and HD 7977 brought the two stars close together, but exactly how close is still an open question. Gaia data suggest they passed within 4000-25000 astronomical units of one another. Now, Kaib and Raymond have shown that the orbits of long-period comets suggest HD 7977 came within 6000-10000 AU of our Sun, setting off a major shower of new comets into the inner solar system.

You can read the preprint paper here [pdf].

These results are filled with many uncertainties of course. For one, the actual distance for HD 7977’s close pass is not well constrained. The margin of error is large, so that the star might have not done anything at all. Second, our map of the Oort cloud is very uncertain. In fact, it exists at this time only in theory, as it has never been directly observed. Astronomers hypothesize its existence based on the orbits of the long period comets that they have documented for the past few centuries, all coming from that distant region. So while it appears to exist, that existence remains unproven.

These uncertainties thus make the conclusions of this paper interesting but unconfirmed. Nonetheless, they are fascinating, because they are strongly suggestive, and hint at the impact of the galaxy and its stars on the evolution of our solar system itself. That impact is real, though tracing its history is difficult because of the vast time scales and distances. It appears the Gaia data and computers are giving us a first glimpse into that past history.

South Korea’s space agency wants to accelerate its launch capabilities

10:53 am

The head of South Korea’s space agency KASA, Oh Tae-seok, yesterday outlined plans to to accelerate the launch cadence of its government-built Nuri rocket, while also beginning research into building a second spaceport along with a specific launchpad for private companies.

Oh Tae-seok, head of KASA, held a press briefing at the agency in Sacheon, South Gyeongsang Province, on Thursday. “This week, the assembly of the first, second, and third stages of the fifth Nuri rocket will be completed,” he said. “From next week, we will begin full assembly of the entire rocket, and after the Launch Management Committee in early August, a September launch is expected.”

Oh also stressed the need to build a repeated launch system after the fifth launch to advance toward an era of “commercial launch services.” “To ensure the economic viability of Nuri, changes are needed in standardization and specification, as well as contracting methods and launch site operations, in addition to the advancement project,” he said. “We are preparing for four launches from 2029 to 2032.”

In addition, the agency plans to accelerate construction of the second spaceport. KASA began accepting candidate site applications for the second spaceport on the 22nd of this month. “We will select the final candidate site in October this year and aim to begin the project in 2028,” the agency said Thursday.

This second news report quoted Oh as also saying this:

“In the 2030s, rather than the current R&D approach, we should consider converting to a system where we commission launch services through purchasing, as NASA does.” This is a model similar to how NASA purchases launch services from private companies such as SpaceX.

In other words, even as he accelerates the use of Nuri, Oh wants to replace it with private rockets. Whether he can do both is questionable, because they act to cancel each other. A cheaper and viable government rocket will make it difficult for private startups to compete.

At the moment South Korea has one truly viable rocket startup, Innospace, which has one launch failure and hopes to try again before the end of the year. That it does not launch in South Korea but in Brazil suggests KASA has not been as cooperative with the commercial sector as Oh wants. His statements about building a launchpad for the private sector suggest he is aware of this.
