China launches 18 satellites

China today successfully placed 18 more Spacesail or Qianfan satellites in orbit, its Long March 6A rocket lifting off from Taiyuan spaceport in northeast China. No word on where the rocket’s lower stages crashed inside China.

This was the sixth launch for this internet satellite constellation, intended to provide Chinese citizens service similar to Starlink, but controlled by the Chinese government. At present it has 119 satellites in orbit, out of a planned 648 in the constellation’s first phase. That phase was supposed to be completed by the end of this year, something that now seems very unlikely. The constellation’s final configuration could have as many as 10,000 satellites.

The leaders in the 2025 launch race:

133 SpaceX
62 China
13 Russia
13 Rocket Lab

SpaceX still leads the rest of the world in successful launches, 133 to 103.

Layers of Martian ash

Layering on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 31, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this as “layering”, which surely is an apt description. As the latitude is 9 degrees south, this location is within the dry tropics of Mars, where no near surface ice has yet been found. Thus, the terraced layers of this low 20-foot-high mesa are not indicative of the many glacial climate cycles found in the mid-latitudes.

Instead, we are looking at sedimentary layers of rock or dust, laid down over time and later exposed by erosion.

So what caused the layers? And what is causing them to be exposed, one by one? As always the overview map helps provide a possible explanation.

ESA awards contract to Italian company to provide an ocean landing platform

Avio's proposed reusable upper stage
Click for original.

The European Space Agency (ESA) has awarded the Italian company Ingegneria Dei Sistemi (IDS) a contract to build an ocean vessel for recovering the planned reusable test upper stage being built by the Italian rocket company Avio, as shown in the graphic to the right.

In late September, ESA awarded a €40 million contract to Avio for the design of a reusable rocket upper stage. The project scope encompasses preliminary design work, including system requirements and technological solutions, for both the launch system and the ground segment. According to the agency, the project has a number of potential applications, including as an evolution of Avio’s Vega family of rockets.

On 15 October, IDS announced that it had been awarded the contract to design the project’s recovery vessel, which falls under the systems ground segment. The company has subcontracted Italian naval systems consultancy Cetena and Norwegian shipbuilder Vard to assist with the project.

ESA very clearly is trying to encourage the development of reusable rockets by Europe’s private sector, but the nature of this particular program seems badly thought out. Rather than have Avio design the system in its entirety, in order to make it as efficient and profitable as possible, it appears ESA is micromanaging the design process, and thus bringing other subcontractors in who are outside Avio’s control. As a result, the final demo might work, but it is not likely it will be competitive with the private reusable rockets being built in the U.S. and elsewhere. Too many cooks in the kitchen.

South African red tape will likely delay Starlink there for years to come

According to an article in South Africa yesterday, regulatory red tape and political demands in South Africa will likely block approval of Starlink in that country for years to come, if not forever.

Minister of Communications and Digital Technologies Solly Malatsi gazetted a draft policy direction on the role of EEIPs [Equity Equivalent Investment Programme] in the Information and Communication Technologies (ICT) sector on 23 May 2025. He explained that rules requiring electronic communications service providers to have 30% historically disadvantaged ownership prevented some companies from contributing to the country’s transformation in ways other than traditional ownership.

The Broad-Based Black Economic Empowerment (B-BBEE) Act and the ICT Sector Code supported the use of EEIPs to allow qualifying multinationals to meet empowerment obligations through alternatives. These can include investing in local suppliers, enterprise and skills development, job creation, infrastructure support, research and innovation, digital inclusion initiatives, and funding for small businesses.

However, the Independent Communications Authority of South Africa’s (Icasa) ownership regulations do not provide for EEIPs.

In other words, the laws contradict each other, and to make it possible to issue any licenses for a foreign company like SpaceX, the government needs to resolve this conflict. That is expected to take years of political maneuvering.

Even if this issue is resolved, SpaceX has already said it would not agree to the racial quota system proposed. It has offered to instead provide Starlink for free to 5,000 schools. It is not clear if politicians in South Africa will consider that sufficient.

Scientists find that three normally incompatible substances can interact in the alien conditions on Titan

Scientists have discovered that, under the very cold conditions on Titan, three normally incompatible substances — methane, ethane and hydrogen cyanide — can mix together in a way that previously was considered impossible.

The background to the Chalmers study is an unanswered question about Titan: What happens to hydrogen cyanide after it is created in Titan’s atmosphere? Are there metres of it deposited on the surface or has it interacted or reacted with its surroundings in some way? To seek the answer, a group at NASA’s Jet Propulsion Laboratory (JPL) in California began conducting experiments in which they mixed hydrogen cyanide with methane and ethane at temperatures as low as 90 Kelvin (about -180 degrees Celsius). At these temperatures, hydrogen cyanide is a crystal, and methane and ethane are liquids.

When they studied such mixtures using laser spectroscopy, a method for examining materials and molecules at the atomic level, they found that the molecules were intact, but that something had still happened. … In their analysis, they found that hydrocarbons had penetrated the crystal lattice of hydrogen cyanide and formed stable new structures known as co-crystals.

Not surprisingly, this result suggests that the alien environment on Titan includes a lot of very unexpected chemistry, some of which we right now cannot predict, or even imagine. While exciting, it also suggests that NASA’s Dragonfly mission to Titan will face challenges that make that mission far more risky. It could quickly fail once it arrives, because of this alien environment.

Such a failure will of course help engineers design later missions, but Dragonfly is a very expensive mission, already overbudget at $3 billion. It might have made more sense to fly a fleet of small and cheaper missions to Titan to begin with, to lower the risks.

Sadly, that is not NASA’s plan.

Thailand studying feasibility of establishing its own commercial spaceport

Thailand
Click for source.

Thailand’s government has begun a study to find out whether it makes financial and technical sense to establish its own commercial spaceport in that country.

The Geo-Informatics and Space Technology Development Agency (Public Organisation), or GISTDA, organised a seminar titled “Thailand’s Future Opportunities for Spaceport Development” on October 15 at iConsiam. The seminar aimed to establish a platform for exchanging views and gathering suggestions from all sectors regarding the future of a “Spaceport” in Thailand, underscoring a critical juncture for the country to elevate its presence on the global space stage fully.

Pakorn Apaphant, GISTDA Director, revealed that GISTDA is currently conducting a feasibility study for establishing a Spaceport in Thailand, in collaboration with the business consulting firm KPMG Phoomchai Business Advisory Ltd. The comprehensive study covers economic aspects, business strategy, environmental and social impacts, as well as a nationwide survey of potential sites to evaluate the most suitable location for future development.

As the map to the right shows, Thailand’s geography is not perfect. It has plenty of coast, in the country’s south, but at any location the trajectory of most launches would almost have to cross land of Thailand or other countries. Nonetheless, with the advent of reusable lower stages, such considerations will eventually become less of a concern.

Three launches since yesterday

The beat goes on. Since yesterday there were three launches, one by China and two by SpaceX.

First, China’s Long March 8A rocket placed the twelfth set of satellites in the Guowang internet constellation, eventually aiming to be 13,000 satellites strong. China’s state-run press did not specify the exact number of satellites. Based on previous launches using the Long March 8A, the number was likely nine, bringing the number of this constellation’s satellites now in orbit to 96.

The launch was from China’s coastal Wenchang spaceport, and had a flight path that dumped the lower stages of the rocket near islands in the Philippines.

Next, SpaceX placed 21 satellites into orbit for the Pentagon, its Falcon 9 rocket lifting off from Vandenberg in California. This was the second launched by SpaceX for this military communication constellation, dubbed Tranche-1, intended to be 158 satellites total. The first stage completed its seventh flight, landing on a drone ship in the Pacific. The fairing halves completed their third and fourth flights respectively.

Finally, SpaceX launched another 28 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its third flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

133 SpaceX
61 China
13 Russia
13 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 133 to 102.

Indian rocket startup Skyroot hires Exolaunch to handle satellite integration and deployment

The Indian rocket startup Skyroot yesterday signed a partnership agreement with the company Exolaunch to handle the integration and deployment of satellites once its Vikram smallsat rocket begins launching.

Through this agreement, Exolaunch will integrate and deploy customer satellites on Skyroot’s Vikram series of launch vehicles, beginning with the Vikram-1 orbital missions. Exolaunch will provide its flight-proven deployment technologies for Skyroot customers across dedicated and rideshare launches. The partnership also includes the use of Exolaunch’s EXOtube payload stacks, designed to optimize multi-payload rideshare configurations, streamline constellation launches, increase mission flexibility, and enhance vehicle utilization.

While Skyroot has not yet launched, Exolaunch is very well established, having “a decade of flight heritage and 582 satellites launched across 39 missions to date.” Since Skyroot has no experience yet in these matters, having Exolaunch do it makes satellite companies more likely to buy space on its rocket.

Until recently Skyroot had been targeting a first launch before the end of this year. That schedule has now changed. According to the company’s webpage, that first launch is now scheduled sometime in 2026.
