BepiColumbo’s team prepares for arrival at Mercury in the fall

The arrival plan for BepiColombo

After eight years of travel through the inner solar system to get to Mercury, the European/Japanese dual orbiter mission BepiColombo is finally getting close to arrival at Mercury in the fall, and the science team has been doing rehearsals to prepare for that orbital insertion.

Teams must align timelines, verify readiness criteria and maintain a common understanding of what constitutes a ‘go’ or ‘no-go’ decision. During one recent simulation, controllers were confronted with an anomaly that forced them to abort and re-schedule a planned separation scenario. “It generates continuous discussions and iterations between the different teams,” Nacho adds.

The exercise highlighted an essential aspect of Mercury arrival: success depends not only on operating the spacecraft, but on ESA and JAXA working together as one team.

That arrival is made more complicated in that BepiColombo is not a single orbiter. It is made up of the following parts:

  • The Mercury Transfer Module (MTM), which provided the service module and ion engines for the journey, including six fly-bys of Earth, two ofVenus, and six of Mercury
  • The Mercury Planetary Orbiter (MPO) from the European Space Agency (ESA)
  • The Mercury Magnetospheric Orbiter (Mio) from Japan’s space agency JAXA
  • The Mio Sunshield and Interface Structure (MOSIF), which protected everything during its journey in the inner solar system close to the Sun

The graphic to the right outlines the arrival plan. First the MTM must separate. Then the two orbiters enter Mercury orbit. Next Japan’s Mio separates and is deployed in its own orbit. Then the sunshield is ejected from Europe’s orbiter and it moves into its planned orbit.

As the spacecraft uses ion engines, with low but continuous thrust, these maneuvers can take weeks.

Both orbiters have complementary orbits to study different aspects of the planet. Europe’s orbiter will orbit closer to get a better look at the planet, while Japan’s Mio’s orbit is highly elliptical, to study the planet’s magnetic field.

During the journey to Mercury BepiColombo overcome several problems. First, the Covid panic threatened operations by limiting staffing and preventing normal behavior. Next the solar panels failed to produce the expected power, a problem that appears to still exist but which has not prevented operations. Finally, its thrusters produced less thrust than expected during a mid-course correction in 2024, causing an eleven month delay in arrival.

It is now however about to arrive. Let us hope that arrival proceeds as planned.

Interior Dept requests advice from offshore launch platform companies

11:11 am

Because it appears the space industry might soon wish to launch rockets from offshore platforms within the 200 mile ocean economic zone the Interior Department administers and issues leases for oil rigs, its Bureau of Ocean Energy Management (BOEM) issued on July 7, 2026 a request for information (RFI), asking public input before it creates its regulatory framework for such platforms.

BOEM is considering whether these concepts may encompass the repurposing of existing offshore infrastructure (e.g., mobile offshore drilling units or other fixed platforms previously used for oil and gas operations), as well as the potential development of new, purpose-built offshore facilities dedicated to commercial space launches, space re-entry, and related activities on the OCS. The siting, construction, and operation of such platforms or facilities—whether repurposed or newly constructed—would likely implicate multiple Federal authorities and legal frameworks. BOEM is issuing this RFI to improve its understanding of these considerations and to inform potential future interagency coordination, policy development, or guidance before any policy positions or decisions are finalized.

The only previous American offshore launch platform, SeaLaunch, always launched outside the economic zone, far out to sea, but that company has been defunct for more than a decade. A new offshore launch company, Seagate, is partnering with Lockheed Martin and Firefly to develop a new platform, and it appears it might launch Firefly’s Alpha rocket closer to home.

In its RFI, BOEM references President Trump’s Executive Order 14369 (“Ensuring American Space Superiority”), which requires government agencies to establish policies that encourage the space sector. Thus, it appears the RFI is not to burden the private sector with more red tape, but to facilitate the legal framework for it to operate within the 200-mile economic zone.

As always, however, we must recognize that Trump will not be in office forever, and that future presidents might act more like Joe Biden, and use such regulation to squelch the industry.

French startup The Exploration Company opens U.S. subsidiary

10:51 am

Nyx drop test
June 2026 successful drop test of Nyx prototype

The French startup The Exploration Company (TEC), which is building the Nyx reusable cargo capsule for supplying future space stations, has now established a U.S. office in Houston, with the clear intention of competing for NASA and Space Force contracts.

Located in Houston near NASA Johnson Space Center, the TEC Rapid Innovation Lab brings together engineers, designers, and operators in a space built for efficient, rapid innovation. At its center is a full-scale mockup of the future Nyx crew capsule, enabling teams to prototype, test, and refine crew interfaces in close collaboration with partners, astronauts, and NASA personnel.

…The company also established TEC Federal, a dedicated U.S. entity designed to serve government customers. Operating as a U.S.-controlled organization, TEC Federal enables participation in U.S. government programs and contracts, while ensuring compliance with applicable regulatory requirements.

Since its inception in 2021 the company has styled itself as a European company providing cargo and manned-space-related services for the European Space Agency (ESA). The problem is that ESA is not building any space stations. It is thus a very limited market. This new action tells us the company has recognized that the customers for Nyx — the five American space stations presently under development — are really in America, and so it is now beginning to shift operations here.

SpaceX’s files FCC application for 100,000 satellites in third generation Starlink constellation

10:02 am

On July 7, 2026 SpaceX filed an application with the Federal Communications Commission (FCC) for permission to expand its Starlink constellation to 100,000 satellites, an a third generation upgrade that will include data and AI capabilities.

According to the technical attachment, these satellites would operate lower than the current Starlink satellites, in two bands of thin shells with nominal altitudes between 323 and 327.5 kilometers and 473 and 477.5 kilometers. The Gen3 satellites described in the filing will be equipped with advanced phased array beam-forming and digital processing technologies, as well as optical inter-satellite links.

SpaceX has authorization to deploy up to 15,000 Gen2 Starlink satellites after receiving approval from the FCC in January of this year. SpaceX has said this authorization will allow the Gen2 system to deliver “gigabit-speed service.”

The application does not actually name this new upgrade “Starlink”, even though it describes in connection with the first two Starlink generations. This filing is also separate from SpaceX’s earlier FCC filing for its proposed million satellite data center “Starmind” constellation.

It is clear that the company is looking to put Starship to use aggressively, once it becomes operational.

Space Force adds two startups to its list of space companies that can bid on its contracts

8:01 am

The Space Force on July 8, 2026 added the rocket startup Relativity and the rocket engine company Impulse Space to its list of approved space contractors, awarding both a $5 million task order to “conduct an initial capabilities assessment.”

The U.S. Space Force’s (USSF) acting Portfolio Acquisition Executive for Space Access awarded two additional Firm Fixed-Price (FFP), Indefinite-Delivery Indefinite-Quantity (IDIQ) National Security Space Launch (NSSL) Phase 3 Lane 1 contracts to Impulse Space and Relativity Federal Inc., a subsidiary of Relativity Space. The two providers join Blue Origin, SpaceX and ULA who were on-ramped in FY24, and Rocket Lab and Stoke Space who were on-ramped in FY25.

…Phase 3 Lane 1 contract provides commercial-like launch services for Space Systems Command’s (SSC) more risk-tolerant missions. The Lane 1 contract focuses on rapid contract award, streamlined integration phases and reduced timelines from award to launch.

What this means is that these two companies will be able to bid on certain projects that are tailored for smaller newer companies in which the Space Force can accept a higher risk of failure.

Back in 2014 the Air Force (which then ran the military’s space operations) was so hidebound it would only entertain bids from one launch company, ULA. SpaceX had to sue to end that monopoly. Even so, for years the Air Force was reluctant to expand this list beyond these companies, which is one reason the Space Force was created. The Air Force wasn’t really interested in space; the War Department needed an agency focused on these assets exclusively.

Since then the Space Force has aggressively expanded this list of approved companies, almost faster than the companies become operational. This has resulted in more launches at lower cost, benefiting both the military and private sector.

China successfully launches and recovers first stage of its new Long March 10B rocket

10:14 pm

The first stage of Long March 10B after recovery
The first stage of Long March 10B after recovery

China’s state run press has now confirmed that today (July 10, 2026 in China) it successfully launched and recovered the first stage of its new Long March 10B rocket on that rocket’s very first launch.

The second link above shows the launch, cued to just before lift-off. The two images to the right come from the third link, a tweet showing the first stage captured on its recovery vessel, using a net catch system. The location of this recovery was in the middle of the South China Sea, about 300 nautical miles west of the Philippines.

Video of the first stage landing is here.

It is not clear if the launch was placing any payloads in orbit, but I will assume so, and add it to my launch count. If this changes I will update.

Either way, China has now joined a very small select group (SpaceX and Blue Origin) capable of landing and recovering a first stage. What is even more impressive about this achievement is that China did it with a completely different recovery technique — a net — that does not require legs (saving weight) that no one else has tried or proposed. Moreover, it demonstrated the ability to bring that stage down precisely and in a controlled manner.

The leaders in the 2026 launch race:

82 SpaceX
45 China
10 Rocket Lab (plus two suborbital HASTE launches)
8 Russia

For the third straight year SpaceX leads the entire world combined in total launches, 82 to 77.

More “Fluvial Processes” on Mars

12:59 pm

More fluvial processes on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 4, 2026 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists label this “Fluvial processes inside crater,” an apt description based not only on the small section of the full image to the right, but on the full image itself. The entire surface of the crater floor’s western end appears filled with glacial material, in many places twisted and warped by past slow motion movements.

I picked out the area in the picture because of its particularly warped nature. It appears as if the material in the higher elevations to the upper right have been flowing downward, and in the process have pushed the glacial debris on the crater floor to the southwest.

It also appears that in the higher locations the near surface ice has been sublimating away, giving the surface a corroded look.

Vantor’s 10-satellite imaging constellation now providing high resolution 3D pictures

10:16 am

The Arc de Triomphe in Paris

The satellite company Vantor is now offering high resolution 3D imagery from its 10-satellite constellation at resolutions in some cases able to see objects as small as six inches across.

The Vantor image to the right of the Arc de Triomphe in Paris has such a resolution.

The product is available through two options designed for different mission needs:

  • Rapid 3D: Designed for time-sensitive missions where terrain conditions can change quickly, this product delivers updated 3D terrain within 24 hours of image collection with just a single satellite pass. Accessible via Vantor™ Hub, it delivers 50 cm-class resolution and 4 m accuracy in all dimensions.
  • High-definition (HD) 3D: Designed for missions that require greater fidelity, this product provides detailed 3D maps at 15 cm resolution and 3 m accuracy in all dimensions. Available globally on a project basis, this capability can also be delivered through change-based refresh subscriptions for customers who need to monitor terrain and infrastructure over time.

The company began launching its 10-satellite constellation in 2024 under the ownership of Maxar. In 2025 the Maxar Intelligence division running the project was rebranded Vantor. Its constellation “can revisit the same location on Earth 15x per day, with downlink speeds as fast as 15 minutes after collection.”

The commercial and military possibilities of this technology can hardly be measured. I also suspect that Vantor and the War and State departments have a close working relationship as to the release of this data and who can get it.

Vantar is also once again demonstrating the advantages of freedom, competition, and capitalism. A decade ago the military struggled to build on its own such imaging constellations. Little got built, though budgets ballooned. Since it shifted to the capitalism model, hiring private companies to do the work, it has gotten it done fast, cheap, and with capabilities the military couldn’t dream of in the past.

Private company Auxilium Biotechnologies successfully prints kidney and liver tissues on ISS

9:51 am

The private company Auxilium Biotechnologies today announced it has successfully printed kidney and liver tissues as well as manufactured 28 nerve implants during a recent mission on ISS.

During the mission, Auxilium’s AMP-1 orbital bioprinter successfully manufactured kidney, liver, and cartilage tissues while also producing 28 nerve repair implants. The achievement represents the first demonstration of kidney tissue manufacturing in space, the first demonstration of liver tissue manufacturing in space, and the first mission to manufacture three distinct tissue types during a single spaceflight. The production of multiple tissue types and clinically relevant nerve repair implants represents the first demonstration of a scalable, multi-product biomanufacturing platform in space.

Equally important, the mission demonstrated the ability of a single autonomous manufacturing platform to produce both living tissues and implantable medical products during the same flight. The simultaneous production of multiple tissue types alongside 28 nerve repair implants highlights not only the versatility of the platform, but also its scalability and higher-throughput manufacturing in space.

Because NASA forbids the manufacture of any products on ISS for sale later, this experiment by Auxilium is merely a demonstration of the technology. The company however already has a deal to do this work on Vast’s space stations, and appears in negotiation with the Starlab space station as well. Once those private stations launch, it is now certain that Auxilium will rent space on those stations to begin production and sale of these medical products.

In other words, these space stations have a growing and viable customer base, outside of NASA and the government.

Blue Origin to seek private funding beyond Jeff Bezos

9:39 am

For the first time Blue Origin now intends to raise additional outside private funding, $10 billion total, beyond the billions Jeff Bezos has been investing in company for the past decade.

In a memo sent to employees on Wednesday and seen by Business Insider, Blue Origin CEO Dave Limp said the company would raise [$10 billion in] funds at a $130 billion valuation.

…The New York Times’ DealBook earlier reported on the raise and said it is being led by asset management firm Coatue Management with a $2 billion contribution from Bezos.

By my count in 2020, Bezos had pumped somewhere between $2 to $6 billion into Blue Origin, the funds coming from sales of his Amazon stock beginning in 2017. With this new investment round, he will have committed another $2 billion.

Unlike the earlier funding from Bezos, however, this new investment is occurring with Limp as the company’s CEO. When the previous funding occurred the company’s CEO was Bob Smith, who essentially wasted more than five years from 2017 to 2023 accomplishing nothing. No rockets got built, engine development was delayed endlessly, and good engineers were seen fleeing the company. Since Limp took over in 2024 he has aggressively worked to change the moribund culture he inherited from Smith. Under his leadership this funding could really make a difference.

Rocket engine startup Venus Aerospace raises $91 million in investment capital

9:13 am

Following a successful suborbital test flight of its rotating detonation rocket engine (RDRE) in May, the rocket engine startup Venus Aerospace has now raised an additional $91 million in private investment capital, on top of $80 million raised previously.

Venus Aerospace today announced the close of a $91 million Series B financing led by Mercury Fund, a Houston-based venture capital firm, with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity, Seraph Group, Trousdale Ventures, and other new and existing strategic and institutional investors.

…Unlike conventional rocket engines, which burn fuel through subsonic combustion,Venus’ RDRE employs a continuous supersonic detonation wave that rotates around the combustion chamber. The result is the most efficient rocket engine architecture ever flown, by a margin of 15 percent.

The company intends to develop the engine for sale to many rocket companies and across many platforms. It already had a significant investment from Lockheed Martin, which tested its own RDRE engine in January 2026.

SpaceX launches 29 more Starlink satellites; flies first stage for 36th time

8:42 am

SpaceX last night successfully launched another 29 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral Space Force station in Florida.

The first stage (B1067) completed its 36th flight (31 days after its previous mission), landing on a drone ship in the Atlantic. With this flight this booster maintained its second place position, behind the space shuttle Discovery, in the rankings for the most reused launch vehicle:

39 Discovery space shuttle
36 Falcon 9 booster B1067
34 Falcon 9 booster B1071
33 Atlantis space shuttle
33 Falcon 9 booster B1063
31 Falcon 9 booster B1069
29 Falcon 9 booster B1077
29 Falcon 9 booster B1078

Anton Karas – Theme from the Third Man

6:01 pm

An evening pause: The movie, The Third Man (1949), was directed by Carol Reed and starred Orson Welles. This theme, played throughout, made the film something special. This live performance is from 1950. I like especially how it shows so clearly the intricate finger play.

Bright spokes in Saturn’s rings

11:46 am

Bright spokes in Saturn's rings
Click for original image.

Cool image time! The picture to the right, cropped slightly to post here, was taken on December 26, 2008 from a distance of 350,000 miles by the Cassini spacecraft as it orbited Saturn. The resolution is about 37 miles per pixel.

I think sunlight is coming from the upper left, its light bouncing off the rings and thus making the those spokes bright and visible.

In the viewing geometry in which Cassini is looking approximately in the direction of the sun (called high phase), the spokes appear white against the rings because the very small particles comprising the spokes preferentially scatter light forward (in this case, toward Cassini).

At least that’s one theory for explaining the spokes that appear randomly and for only short periods within Saturn’s rings, sometimes bright, sometimes dark, depending on the angle of the Sun. According to a Hubble press release from 2023, the spokes are formed due to an interaction between Saturn’s magnetic field, the solar wind, and the tiny particles in the rings.

“The leading theory is that spokes are tied to Saturn’s powerful magnetic field, with some sort of solar interaction with the magnetic field that gives you the spokes,” said Simon. When it’s near the equinox on Saturn, the planet and its rings are less tilted away from the Sun. In this configuration, the solar wind may more strongly batter Saturn’s immense magnetic field, enhancing spoke formation.

Planetary scientists think that electrostatic forces generated from this interaction levitate dust or ice above the ring to form the spokes, though after several decades no theory perfectly predicts the spokes. [emphasis mine]

Just another strange alien phenomenon in space that remains unsolved. All we really know is that the spokes appear, remain visible for at most a rotation or two of the rings, and then disappear.

Japan’s Ispace signs deal with SpaceX to use Starship for lunar cargo delivery

9:14 am

Ispace's mobile cargo system
Click for original.

The Japanese lunar lander startup Ispace yesterday announced it has signed an agreement with SpaceX to use its Starship lunar lander to transport cargo to the Moon’s surface.

The Ispace graphic to the right shows the company’s proposed “Mobile Cargo System” on the Moon after deployment from Starship.

In preparation for the new business offering, Ispace has secured 500 kilograms of payload capacity on Starship, scheduled for launch as early as 2030. Ispace is offering global customers with relatively small payload delivery needs, weighing 500 kilograms or less, a comprehensive service to integrate, transport and operate their payloads on the Moon.

As part of the integration process, Ispace will assess each customer’s payload requirements and implement the quality control necessary for lunar transportation. Ispace will then integrate multiple payloads into the dedicated “Mobile Cargo System” in development by the company and provide services, including interface coordination with Starship as part of the system. Upon landing on the Moon, Ispace aims to provide operational support through the “Mobile Cargo System” to ensure the smooth deployment of payloads onto the lunar surface, their movement across the lunar surface, and access to other infrastructure.

Ispace is clearly hoping this cargo system will be of interest to NASA for its Moonbase project. It is also something that will appeal to other commercial customers who want to get a payload to the Moon cheaply.

Satellite company Loft Orbital signs multi-launch deal with European rocket startup Maiaspace

8:59 am

Because it appears SpaceX is ending its multi-payload Transporter Falcon 9 launches for smallsats after 2028, the satellite company Loft Orbital has now signed multi-launch deal with European rocket startup Maiaspace.

Although the announcement provided few details, it did share that the first flight was expected in 2028. In an 8 July press release, MaiaSpace explained that the multi-launch agreement “consolidates its launch manifest,” adding that the company has now sold more than half of all capacity for its first three years of operation.

To date, all Loft Orbital satellites have been launched aboard SpaceX Transporter rideshare missions. However, according to reporting from SpaceNews, in recent weeks, several customers of these missions have said that SpaceX is not accepting Transporter reservations beyond late 2028 or early 2029. The publication quoted Rocket Lab CFO Adam Spice as saying that there “seems to be a panic setting in.”

If the SpaceX aspect of this story is true, it means there will now be a slew of new satellite customers for all the many rocket startups, not just Maiaspace. In fact, it is puzzling Loft Orbital went to Maiaspace first. That company does not expect to do its first orbital test flight until late ’27. Meanwhile the Spanish startup PLD, the Indian startup Skyroot, the South Korean startup Innospace, the German startups Isar and Rocket Factory, and the American startups Stoke Space and Relativity are all expected to try their first launches before the end of this year. In addition, Rocket Lab has its Electron rocket, and hopes to launch its new Neutron rocket also by the end of this year.

That SpaceX is no longer taking reservations for Transporter flights after late 2028 also gives us a hint as to the company’s future plans for its Falcon 9 rocket. There has been much speculation it would be replaced by Starship, and this news suggests that transition from Falcon 9 to Starship is now beginning.
