Chinese solid-fueled rocket fails during launch

9:26 am

The commercial division of a Chinese space agency, dubbed CAS Space, late yesterday experienced a launch failure of its solid-fueled Kinetica-1 rocket, lifting off from the Jiuquan spaceport in northwest China.

A statement by the pseudo-company described the failure tersely:

We can confirm that the first two stages were nominal. Stage 3 lost attitude three seconds after ignition and the self-destructing mechanism was activated.

Nothing was said about where the first two stages crashed inside China, or whether they landed near habitable areas.

According to the first link above, this was the second launch failure by China in 2024, which is incorrect. This was the third launch failure for China (see here and here for previous two). That article also says this was the 68th total launch this year, suggesting China has completed 66 successful launches. This does not jive with my count, which presently says China has had 64 successful orbital launches this year. I suspect the two additional launched might have been suborbital tests — such as first stage hop tests (here, here, and here) — which I do not include in these totals. It also might be including the accidental launch of one first stage during a static fire test when it broke free and launched itself unintentional.

More recent information from my readers (see the comments below) suggests that, though the numbers above are not correct, my own count for China’s total successful orbital launches needs adjusting as well. I had marked a March 13th Chinese launch as a failure because the satellites were not placed in their proper orbit. However, using their thrusters engineers were eventually able to get them into place and they are operating. I have therefore increased China’s totals below by one.

The leaders in the 2024 launch race:

134 SpaceX
65 China
17 Russia
14 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 154 to 97, while SpaceX by itself leads the entire world, including American companies, 134 to 117.

Russia launches earth resources satellite

9:53 am

Russia today successfully launched the last in a five-satellite constellation of satellites focused on mapping Earth resources, its Soyuz-2 rocket lifting off from Baikonur in Kazakhstan.

The rocket’s core stage and four side boosters fell into frequently-used drop zones in Kazakhstan and Russia.

Dubai-based AI/3D printing company successfully test fires an aerospike engine

LEAP71's aerospike test engine

The Dubai-based startup LEAP71, focused on using AI software to quickly develop rocket engine designs it can then 3D print, has successfully test fired a prototype aerospike engine on December 18, 2024 during a static fire test campaign conducted in the United Kingdom.

Aerospikes are more compact and significantly more efficient across various atmospheric pressures, including the vacuum of space. They forego the conventional bell-shaped nozzle by placing a spike in the center of a toroidal combustion chamber [as shown in the photo to the right]. Since it is surrounded by 3,500ºC hot exhaust gas, cooling the spike is an enormous challenge.

Josefine Lissner, CEO and Co-Founder of LEAP 71, stated: “We were able to extend Noyron’s physics to deal with the unique complexity of this engine type. The spike is cooled by intricate cooling channels flooded by cryogenic oxygen, whereas the outside of the chamber is cooled by the kerosene fuel. I am very encouraged by the results of this test, as virtually everything on the engine was novel and untested. It’s a great validation of our physics-driven approach to computational AI.”

The spike in the center acts as one wall of the nozzle, and the changing pressure of the atmosphere acting as the other side of the nozzle, allowing the nozzle size to change as the rocket rises, thus making its thrust as efficient as possible.

This test was apparently with a small scale prototype, not a full scale engine. LEAP71 engineers are going to have to go though a lot more iterations using their AI software and 3D printing to get to a version usable on a rocket. The company claims that development will go far faster this way. That this company did its testing in the UK but is based in Dubai suggests its capital comes from that Middle Eastern country, which is trying to develop a space industry of its own, but it is mainly relying on British designers — at this point — to get things done.

It will have to do so quickly, since another startup, German-based Polaris Spaceplanes, in November 2024 actually completed the first test flight ever of a prototype using an aerospike engine.

After decades of speculation about the advantages of an aerospike engine but no successful flights, we now have a race between two companies to be the first to fly one, and the effort is going on in Europe.

SpaceX launches 21 Starlink satellites

10:44 pm

SpaceX tonight successfully launched 21 Starlink satellites, its Falcon 9 lifting off from Kennedy in Florida. Thirteen of the satellites were configured for direct-to-cell capabilities.

The first stage completed its fourteenth flight, landing on a drone ship in the Atlantic.

The leaders in the 2024 launch race:

134 SpaceX
64 China
16 Russia
14 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 154 to 96, while SpaceX by itself leads the entire world, including American companies, 134 to 116.

Tonight’s launch was also the 250th worldwide in 2024, a record that approximately triples the average number of successful launches each year from 1957 to 2017, when SpaceX and China began to ramp up their launch counts.

NASA awards four companies contracts to provide communications for operations in Earth orbit

11:30 am

Capitalism in space: Rather than continue to build its own constellation of communications satellites, NASA yesterday awarded four companies contracts to provide that service to the agency’s many Earth orbit operations.

The work will be awarded under new Near Space Network services contracts that are firm-fixed-price, indefinite-delivery/indefinite-quantity contracts. Project timelines span from February 2025 to September 2029, with an additional five-year option period that could extend a contract through Sept. 30, 2034. The cumulative maximum value of all Near Space Network Services contracts is $4.82 billion.

The companies are Intuitive Machines, SSC Space, Viasat (based in Georgia), and the Norwegian company Kongsberg Satellite services.

Not only will these companies provide a better service faster and at less cost than the NASA TDRS satellite constellation, that there are four of them provides redundancy as well as fosters competition.

Defunct Pentagon weather satellite breaks up

10:40 am

According to the Space Force as well as two commercial space tracking companies, a defunct military weather satellite launched in 1997 has broken up into more than fifty pieces.

The satellite, dubbed DMSP-5D2 F14, was in a sun-synchronous orbit over the poles. What makes the break-up significant is that it is not the first of this design of weather satellites to do so.

DMSP-5D2 F14 is part of a family of spacecraft that have suffered breakups in orbit. The F12 satellite broke up in October 2016, following the breakup of F13 in February 2015. In 2004, the F11 spacecraft broke up, creating 56 pieces of tracked debris. All the satellites had a battery assembly with a design flaw that made them vulnerable to explosion.

A similar spacecraft design was used for a line of civilian polar-orbiting weather satellites operated by the National Oceanic and Atmospheric Administration. The NOAA-16 satellite broke up in November 2015, followed by NOAA-17 in March 2021.

Overall the military launched nine satellites of this design, while NOAA launched three. Of these twelve satellites six have now broken apart. We should expect a large percentage of the remaining six to also break up.

This story explains why in the last ten years a number of companies have appeared attempting to develop the technology to remove space junk. There is a desperate need in the satellite industry for this capability, and those space junk companies are aiming to make profit from this need.

Note I do not expect or want the government to take the lead in this. This issue is mostly a need of the satellite industry, of which the world’s governments are merely just one more participant. This industry should band together to set up a fund to pay for this work, with those governments joining as just one more partner.

Liechtenstein signs the Artemis Accords

10:16 am

The tiny nation of Liechtenstein in Europe yesterday became the 52nd nation to sign the Artemis Accords.

The full list of nations now part of this American space alliance: Angola, Argentina, Armenia, Australia, Austria, Bahrain, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, France, Germany, Greece, Iceland, India, Israel, Italy, Japan, Liechtenstein, Lithuania, Luxembourg, Mexico, the Netherlands, New Zealand, Nigeria, Panama, Peru, Poland, Romania, Rwanda, Saudi Arabia, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

There has been a flurry of new nations signing the accords since the November election of Trump. I suspect his coming encouraged these nations to sign, knowing the moribund leadership of Biden will soon be replaced with something more robust. It is also likely that these nations see a renewal of Trump’s original goals for the Artemis Accords, to create an international alliance, led by the United States, with the goal of overcoming the Outer Space Treaty’s limitations on private property.

I hope this turns out to be true. This alliance gives Trump a powerful lobby he can wield to force change.

SpaceX and Rocket Lab complete two launches overnight

10:04 am

Though one SpaceX launch early last night had a launch abort, both SpaceX and Rocket Lab completed additional launches later in the evening.

First, SpaceX completed its second Bandwagon in which 30 payloads were sent to mid-inclination orbits, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage flew its twenty-first flight, landing successfully back its landing site at Vandenberg. The two fairings completed their 14th and 18th flights.

Next, Rocket Lab completed its sixth launch of sixteen for the commercial satellite company Synspective, its Electron rocket lifting off from one of its two launchpads in New Zealand. This was the 14th successful launch for Rocket Lab in 2024, a significant increase from the nine and eight launches it flew in 2022 and 2023.

The leaders in the 2024 launch race:

133 SpaceX
64 China
16 Russia
14 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 153 to 96, while SpaceX by itself leads the entire world, including American companies, 133 to 116.

SpaceX experiences a launch abort at T-0

10:29 pm

During a launch attempt tonight from Cape Canaveral in Florida, SpaceX experienced a launch abort at T-0 seconds for reasons that have not yet been determined but apparently were complex enough that mission control decided to scrub for the evening. No new launch has been scheduled as yet.

The launch was to have placed four smallsats into geosynchronous orbit. The satellites were built by the satellite company Astranis, which appears to be the first to launch smallsats to geosynchronous orbit. It had already placed one in orbit, and these four satellites expand its constellation.

China launches a communications test satellite

3:36 pm

According to China’s uninformative state-run press, it today launched “a test satellite for communication technology,” its Long March 3B rocket lifting off from its Xichang spaceport in southwest China.

No other details about the satellite were released. Nor did the state-run press provide any information about where the rocket’s lower stages, using very toxic hypergolic fuel, crashed inside China.

As is usual for China, it is doing a lot of launches at the end of the year. Though weather might be a factor, I also suspect it is the ordinary “use-it-or-lose-it” symptom of a government-run communist society. Budgets are set for the year. Government agencies find that they better launch or they will lose that budgeted amount in the next year’s budget.

This might not apply to China but if so it would explain its strange end-of-year launch pattern.

The leaders in the 2024 launch race:

132 SpaceX
64 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 151 to 96, while SpaceX by itself leads the entire world, including American companies, 132 to 115.

Oh no! The sonic booms of SpaceX are coming!

10:00 am

Superheavy after its flight safely captured at Boca Chica
Superheavy after its flight, safely captured at Boca Chica
on October 13, 2024.

When the current (but soon to step down) administrator of the FAA Mike Whitaker testified before Congress in September 2024 and attempted to explain his agency’s red tape that have significantly slowed development of SpaceX’s Starship/Superheavy rocket, he claimed that the sonic booms produced when Superheavy returned to land at the launchpad posed a “safety issue” that needed a detailed review.

“I think the sonic boom analysis [related to returning Superheavy back to Boca Chica] is a safety related incident.”

The sudden introduction of this issue was somewhat out of the blue. While loud, the sonic boom of a rocket launch is hardly a concern. The space shuttle produced the same for decades when it landed, and that was always considered a fun plus to watching the landing. And even if SpaceX begins launching its rockets once a day from any spaceport, that added noise does nothing to hurt anyone. In fact, it is a local signal of a thriving economy.

Since then it appears the leftist “intellectual elitists” that don’t like it when they don’t run everything — which is one reason they now hate Elon Musk — have run a full court press trying to make these rocket sonic booms a cause celebre that can be used to block SpaceX launches.

Vast signs deal with SpaceX for two ISS tourist missions

12:34 pm

Depending on whether it gets NASA contractual approval, the space station startup Vast has now signed a deal with SpaceX for flying two tourist missions to ISS.

These two missions expand Vast’s launch manifest with SpaceX, which includes the company’s Falcon 9 rocket delivering Haven-1 to low-Earth orbit and a subsequent Dragon mission to fly crew to the commercial space station. Haven-1 will also be supported by Starlink laser-based high-speed internet.

Axiom, which has flown three tourist missions to ISS and has a fourth planned, is also bidding for the next two tourist slots NASA has made available for ISS in the coming years. It is not clear who will get those slots. Axiom has the advantage it has done it before, but the rumors that it lost money on those flights and now has a cash shortage work against it. Vast hasn’t yet flown, but it is moving fast to fly and occupy Haven-1 next year. NASA might want to give it at least one of those slots to balance the scales.

Hat tip to BtB’s stringer Jay.
