Firefly to provide the launch rocket for Kratos’ hypersonic test vehicles

8:36 am

The rocket/lunar lander startup Firefly yesterday announced that it has signed a partnership deal with the hypersonic test startup Kratos.

In August Kratos partnered with the Australian company Hypersonix to build 20 scramjet test vehicles for the Pentagon for hypersonic test flights. Firefly with this new deal will provide the launch vehicle for getting those scramjets into the air at the speeds required. In fact, it appears Firefly is now going to do with its Alpha rocket the same thing that Rocket Lab did with its Electron rocket, revising it for suborbital testing.

Rocket Lab has already completed six successful HASTE launches. It will be interesting how quickly Firefly can get Alpha reconfigured and launched in this manner. Some of that schedule will also hinge on Kratos’ ability to provide the scramjets. The press release makes no mention of schedule.

Firefly’s action here continues the recent shift by many American space startups from rocketry and space exploration to defense work that is only tangentially related to space. It appears they are all diversifying to grab the expected rich contracts the Pentagon is expected to hand out to develop Trump’s proposed Golden Dome defense system. It also appears that many are diversifying because they have doubts the civilian space industry can sustain them, by itself.

The Spanish rocket startup PLD yesterday unveiled the first of two full-scale qualification units it is building to test the design of its Miura-5 orbital rocket, scheduled for a first launch sometime in 2026.

The QM1 unit will serve to qualify two key elements of the launcher. Firstly, the MIURA 5 second stage will undergo a destruction test in the United States to validate the functioning of the Flight Termination System. This test will verify the operation of the explosive charges onboard the vehicle, designed to destroy the launcher in the event of an in-flight anomaly.

Secondly, a Wet Dress Rehearsal will be carried out on the rocket’s first stage – a full propellant loading test that replicates all structural load scenarios during the fuelling and pressurisation phase. This test is essential to validate the behaviour of structures under real operational conditions.

By December (next month) the company hopes to complete a second qualification unit for further testing, followed by the flight rocket, which will be shipped to French Guiana for a launch sometime next year.

Right now PLD and Germany’s Isar Aerospace are in the lead in the race to become the first European rocket startup to reach orbit. Isar — which in March attempted one launch that failed — has already shipped the stages to Norway for its second attempt before the end of this year. PLD thus appears to be just behind, though all this could easily change. This is rocket science y’know.

Cracks on Mars

2:47 pm

A cracking Martian surface

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 20, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The camera team describes these features as “ridges,” which in one sense is entirely true. The features are ridges that rise above the surrounding plain. The problem is that they are also cracks, with most showing a distinct central fissure in their middle.

Such double ridged cracks are reminiscent of the surface of dried mud or paint, when it begins to crack and shrink. The surface on each side of a crack pulls away, rising upward slightly as it does so. Is that what we are seeing here, the drying of this surface?

As always, location is critical to understanding the Martian geology.

The DC swamp proposes beating China in space by creating another bureaucracy here on Earth

1:02 pm

Gotta feed those DC pigs!
Gotta feed those DC pigs!

My heart be still: A bi-partisan group of senators, led by Senator John Cornyn (R-Texas), yesterday introduced legislation they claim will help the U.S. beat China in space by creating a new government agency called the “National Institute for Space Research,” designed to encourage research in space tied to the proposed commercial space stations.

Reports indicate that China is launching new modules to its Tiangong space station to meet growing demands for science and to boost international cooperation and is developing a new-generation crew spacecraft with two variants: one for low Earth orbit (LEO) and one for crewed lunar missions. China has been actively promoting international cooperation through Tiangong, offering countries like Oman, Egypt, Pakistan, and others opportunities to participate in space research largely for free or at an extremely low cost. China has also offered to train foreign astronauts, garnering interest from countries like Saudi Arabia, Pakistan, and the UAE to train engineers, scientists, and mission operators for satellite development, and to launch services in which Egypt, Algeria, and Argentina are actively involved. This is a part of China’s broader Belt and Road Initiative, where space cooperation is bundled with tech transfer, loans, development projects, and the like.

This underscores strategic and accelerating investment by foreign adversaries in space-based infrastructure, research, and exploration. China’s ability to offer space-based partnerships to other nations allows it to build soft power and potentially shift international norms in space governance and tech standards.

In response, the Space RACE Act would create a National Institute for Space Research, a federally controlled but independently operated entity designed to coordinate and advance U.S. microgravity research in LEO using next-generation space platforms after the retirement of the ISS.

The last thing this bill will achieve is a stronger American space industry. Rather than funding real research or development in space, this legislation simply creates another Washington government agency supposedly functioning independent of presidential or even congressional oversight (a legal structure the courts have increasingly declared unconstitutional).

This is just more pork. It is also symbolic of the stupidity of our elected officials, who still do not really understand the real reasons beyond the on-going renaissance in America’s space effort. It hasn’t been the government that made it happen. It has been the private dreams of competing companies and individuals, figuring out ways they could make money launching rockets, often with the government acting as a major obstacle. Rather than streamline our bloated government to get it out of the way of this new private sector, these senators want to create more government to dictate how that sector functions.

Ugh. There are times I wish I didn’t have to read the news from DC. It almost always depresses me.

Blue Origin announces plans to upgrade New Glenn to match SLS

12:25 pm

In an update posted today, Blue Origin announced that it is planning to begin upgrades to its New Glenn orbital rocket as soon as its very next launch early in 2026, with those upgrades eventually raising the rocket’s capabilities to that of NASA’s overpriced, cumbersome, and poorly designed SLS rocket.

One of the primary enhancements includes higher-performing engines on both stages. Total thrust for the seven BE-4 booster engines is increasing from 3.9 million lbf (17,219 kN) to 4.5 million lbf (19,928 kN). BE-4 has already demonstrated 625,000 lbf on the test stand at current propellant conditions and will achieve 640,000 lbf later this year, with propellant subcooling increasing the current thrust capability from the existing 550,000 lbf.

The total thrust of the two BE-3Us powering New Glenn’s upper stage is increasing from the original design of 320,000 lbf (1,423 kN) to 400,000 lbf (1,779 kN) thrust over the next few missions. BE-3U has already demonstrated 211,658 lbf on the test stand.

These numbers are a little more than half that put out by the Saturn-5 in the 1960s. New Glenn however has a reusable first stage, so it will cost far less to launch, and will be able to do so frequently. These changes will also make it comparable to SpaceX’s Falcon Heavy.

These engine upgrades however are only a start. Blue Origin also plans to offer a second more powerful version of New Glenn by adding two BE-4 engines to the first stage and two BE-3U engines to the upper stage.

Rocket Lab sets new annual launch record for the company

11:00 am

Rocket Lab today set new annual launch record for the company, quickly scheduling and launching a payload for a “confidential commercial customer”, its Electron rocket lifting off from one of the company’s two launchpads in New Zealand.

This was the 15th orbital launch by Rocket Lab in 2025, beating the record of 14 the company set in 2025. Rocket Lab has also launched its HASTE suborbital version of Electron three times, so the company has actually completed the equivalent of 18 Electron launches this year, though three were not intended to reach orbit.

What made this launch unusual is that it was not announced in advance, and took place suddenly without revealing the customer. It is likely the customer was flying a classified military payload. UPDATE on November 26, 2025: That customer was actually the commercial imagery company BlackSky, launching another one of its satellites for its constellation used by both the military and the public. The company did not explain why it wished its identity hidden during the launch.)

The leaders in the 2025 launch race:

151 SpaceX
71 China
15 Rocket Lab (a new record)
13 Russia

SpaceX still leads the rest of the world in successful launches, 151 to 119.

ArianeGroup confirms it is targeting about six Ariane-6 launches in 2026

10:46 am

According to an official with ArianeGroup, the company that builds and owns the Ariane-6 rocket, it hopes in 2026 to double the launch rate from 2025, from four this year to as many as eight launches next.

The Group is ramping up production at its sites in France and Germany for this purpose. The main stage will be manufactured in Les Mureaux, France, and the upper stage in Bremen, Germany. The latter is considered the heart and brain of the rocket, as it is responsible for controlling the final flight section and reaching the target.

In Bremen, the Group developed a serial production process – similar to assembly line production in car manufacturing. Six upper stages are to be produced in parallel at the plant in future. Ten to twelve upper stages are to be completed and delivered each year. “The target of around ten missions per year should be achieved by 2027,” said Franzeck.

Franzeck’s prediction matches that made two weeks ago by the head of Arianespace, which manages Ariane-6 for ArianeGroup.

It is likely that these companies will get at least six launches off in 2026. Whether they can achieve eight is less likely, based on their past recent record. Reaching 10 launches in 2027 is probably more certain however. They have a big 18-launch contract with Amazon to launch its Amazon LEO satellites (formerly Kuiper), and there is great pressure to achieve those launches quickly because of Amazon’s FCC license requirements.

After this however the future of Ariane-6 remains uncertain. It is too expense (being expendable) to compete in the present launch market. Few European companies want to buy it, and there are numerous new reusable rockets about to begin operations.

Webb captures spiraling shells around massive binary star system

10:31 am

Webb's false color image of shells
Click for original.

Using the Webb Space Telescope, astronomers have been able to produce a reasonably detailed map of the four shells that surround a triple-star system of two massive Wolf-Rayet (W-R) stars and an as-yet unseen supergiant, produced by the interaction of the winds that come off the two W-R stars combined with the interaction of the third.

The image to the right is that Webb false-color infrared image, combined with the data from the ground-based Very Large Telescope in Chile. It has been reduced to post here. The researchers have also produced a 3D simulation mapping out those shells, which you can view here.

The scientists have dubbed this system Apep after the Egyptian god of chaos. From the conclusion of the research paper [pdf]:

We imaged the colliding-wind W-R binary Apep with [Webb] and [the Very Large Telescope]. The JWST images detected four concentric dust shells with highly regular and detailed structures surrounding Apep. The mean expansion speed of the dust shells is 90 ± 4 mas yr−1 and the mean spacing between neighboring shells is 17.30″ ± 0.17″ [in degree seconds]. The shell spacing and expansion speed together suggest an orbital period of 193 ± 11 years, which is independent of uncertainties on the distance, and that the dust structure observed was produced over the past 700 years.

It is believed that Wolf-Rayet stars are primary candidates to eventually go supernova. The data for this system also suggests this system could produce a gamma ray burst as well. At present the astronomers estimate the distance to this system to be about 15,000 light years, which means such an explosion would likely poses no risk to us. It would however give scientists a great view of the event, better by many magnitudes compared to previous such explosions.

India tests new and better restart method for upper stage of its biggest rocket

9:58 am

India’s space agency ISRO has successfully tested new restart method for the engine it uses on the upper stage of its LVM rocket, its biggest rocket that it also intends to use for its manned and interplanetary missions.

For future missions, multiple in-flight restarts of the CE20 engine will be required for mission flexibility towards multi-orbit missions. However, with the present configuration, each restart demands an additional start-up gas bottle and associated systems, leading to a reduction in vehicle payload capability. Hence, achieving boot-strap mode start – where the engine builds up to steady operation without external start-up assistance – is essential.

In this regard, a boot-strap mode start test on the CE20 Cryogenic engine was successfully conducted under vacuum conditions in the High-Altitude Test (HAT) facility at ISRO Propulsion Complex, Mahendragiri on 7th November 2025, for a duration of 10 seconds. A multi-element igniter was employed in both the thrust chamber and gas generator to facilitate boot-strap starting. In this test, following the ignition of the thrust chamber, the gas generator was ignited under tank head conditions, and the turbopumps were started without the use of the start-up system. Subsequently, boot-strap mode build-up and steady-state operation of the engine were successfully demonstrated.

In other words, the engine now be restarted numerous times, giving any payload attached much greater flexibility in positioning and orbital maneuvers. For manned missions this means it can be used to reposition the modules for India’s planned space station, maneuver its manned capsule Gaganyaan, and send interplanetary missions to the Moon and beyond.
