Three launches in the past day

9:45 am

Even as all eyes focused on SpaceX’s 11th test launch of Starship/Superheavy yesterday, there were three other launches in the past fourteen hours taking place on three different continents by China and two different American companies.

First, China placed a technology test satellite into orbit, its Long March 2D rocket lifting off from its Jiuquan spaceport in northwest China. The only information about the satellite is that it will test “new optical imaging.” No information at all was released on where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.

Next, SpaceX placed 24 of Amazon’s Kuiper satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its second flight, landing on a drone ship in the Atlantic.

With this launch, Amazon now has 154 satellites in orbit, out of a planned constellation of about 3,200. Its FCC license requires it to have about 1,600 in orbit by July of ’26, but that goal seems increasingly unlikely to be met. With this launch SpaceX completed its three-launch contract for Amazon. It has contracts with ULA for 46 launches (having so far completed three in 2025), and that company appears ready to launch regularly in the coming months. Amazon’s other launch contracts with Blue Origin’s New Glenn (27 launches) and ArianeGroup’s Ariane-6 (18 launches) however are more uncertain. Neither company has achieved any launches on their contracts, and it is not clear when either company, especially Blue Origin, will ever begin regular launches.

Finally, this morning Rocket Lab placed the seventh radar satellite into orbit for the company Synspective, its Electron rocket lifting off from one of its two launchpads in New Zealand. Rocket Lab has a contract for another twenty Synspective launches over the next few years. The launch also featured a larger fairing that will give the company the ability to launch bigger-sized satellites with Electron.

The leaders in the 2025 launch race, now including yesterday’s Starship/Superheavy launch:

131 SpaceX
60 China
13 Russia
13 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 131 to 101.

PLD issues detailed update on its preparations for first launch in 2026

9:04 am

The Spanish rocket startup PLD today released a detailed video update outlining the work it is doing designing and building its Miura-5 rocket for its first launch, now targeting 2026.

I have embedded that video below. Its engineers and managers describe and show in detail the hard metal they are cutting. Their goal is to produce one upper stage engine every two weeks by the end of this year. The company has already build eight tanks for both stages, and has even tested one tank to failure. PLD has also started construction of its launch site in French Guiana.

All in all, PLD seems moving aggressively towards that first launch, making it one of three European rocket startups on the brink of operations. The other two are Isar Aerospace and Rocket Factory Augsburg, both from Germany.

Swarm satellite constellation detects changes in the Earth’s magnetic field during the past decade

8:01 am

Changes in the magnetic field over the northern hemisphere
Click for original graphic.

The European Space Agency’s three-satellite Swarm constellation, designed to measure the strength of the Earth’s magnetic field at high resolution, has found that the field’s weak and strong regions have shifted and changed in the past eleven years, since the constellation was launched.

The map to the right shows the changes over the northern hemisphere, related to the movement of the north magnetic pole towards Siberia.

[S]ince Swarm has been in orbit the magnetic field over Siberia has strengthened while it has weakened over Canada. The Canadian strong field region has shrunk by 0.65% of Earth’s surface area, which is almost the size of India, while the Siberian region has grown by 0.42% of Earth’s surface area, which is comparable to the size of Greenland.

Similarly, the Swarm data has shown the South Atlantic Anomaly, a major weak area of the field above South America near the equator, has grown significantly eastward towards Africa. That change is important for satellite operations, as spacecraft passing through it experience higher levels of radiation.

All these changes are thought to be because of shifts within the Earth’s molten core from which the dynamo of the magnetic field is generated.

Eleventh Starship/Superheavy a complete success

6:18 pm

Starship and Superheavy during ascent
Starship and Superheavy during ascent today.

On the eleventh orbital test flight today of Starship/Superheavy, SpaceX basically achieved all its engineering goals, with both Superheavy and Starship completing their flights as planned, with Superheavy doing a soft vertical splashdown in the Gulf of Mexico, and Starship doing a soft vertical splashdown in the Indian Ocean.

The Superheavy flown was on its second flight, having flown on test flight #8. Of its 33 Raptor engines, 24 had flown previously. In returning, it successfully used a new configuration of engine burns, first firing thirteen engines, then six, then three.

More significant was Starship’s flight. The engineers had purposely left tiles off in some locations that would experience the greatest heat during re-entry, to find out if the ship could survive a loss of those tiles. It did, and did so in a truly remarkable manner, always flying in a controlled manner, even as it attempted a radical and previously untried banking maneuver as it approached the ocean in order to simulate a return to the launch tower chopsticks at Boca Chica.

Prior to splashdown and during its coast phase, Starship once again successfully tested the deployment of eight dummy Starlink satellites, as well as a relight of one of its Raptor engines to demonstrate it will be able to do a planned de-orbit burn once it enters a full orbit on future test flights.

Once again, the word to describe this flight is remarkable. While no else has yet been able to recover a first stage and reuse it, SpaceX has been doing it with its Falcon 9 for almost a decade, and doing it hundreds of times.

And now it has twice reused a Superheavy booster, out of only eleven test launches. Based on this and the last test flight, the company will almost certainly begin reusing Starship prototypes during next year’s orbital test flights, when it will begin flying full orbits using its third version of Starship, including returns to Boca Chica for chopstick tower catches. Furthermore, expect the deployment of real Starlink satellites on those missions.

The next mission should likely take place close to the end of this year, and it should likely be followed by additional flights about every two months.

While politicians and media swamp creatures focus on the relatively inconsequential race to do an Apollo-like manned landing on the Moon, the real American space program is being run privately by SpaceX, and its goal is to not only go to Mars, but to do so in a manner that will quickly establish a human colony. Along the way the company will help facilitate that government space program, but only as it helps SpaceX learn better how to get humans to Mars.

Most significantly, SpaceX is doing its space program entirely on its own dime. It is being financed by the revenues coming in to the company from the now more than seven million subscribers to Starlink. And those numbers will only rise with time, as Starship begins launching the next generation of satellites with capabilities that will dwarf all of SpaceX’s competitors.

Once again, freedom, private enterprise, and the American dream wins. May all humans someday live under rules that will allow them the same possibilities.

Another round of layoffs at JPL

3:06 pm

The management at the Jet Propulsion Lab (JPL) in California today announced it will be laying off 550 people this week, about 11% of its work force.

As part of this effort, JPL is undergoing a realignment of its workforce, including a reduction in staff. This reduction — part of a reorganization that began in July and not related to the current government shutdown — will affect approximately 550 of our colleagues across technical, business, and support areas. Employees will be notified of their status on Tuesday, Oct. 14.

As the statement makes clear, this reduction is unrelated to the government shutdown, and is also mostly unrelated directly to the 24% budget cut the Trump administration wishes to impose on NASA. JPL has had major management issues in the last few years, including two previous rounds of layoffs of similar amounts. Much of these budget issues stem from the cancellation by NASA of the Mars sample return mission, which JPL was to play a major part. That money is gone, and even if the mission is resurrected, JPL is almost certainly not going to play a major part.

Michael Knowles – Celebrating Columbus

11:01 am

A mid-day pause: I posted twice in the past, but think it should be seen again. As I wrote in 2021,

On this day when all should be celebrating Christopher Columbus and his willingness “sail beyond the sunset,” to use a phrase from Tennyson, this short video give us an accurate picture of the man, his times, and his achievements. It also puts the lie to the bigoted, hateful, leftist slanders that have been used in recent years to poison his legacy.

Welsh university delivers spectometer for Europe’s Franklin Mars rover

9:16 am

Aberystwyth University in Wales this week delivered the spectometer instrument, dubbed Enfys, to be installed on Franklin Mars rover being built by the European Space Agency (ESA) and now scheduled for launch in 2028.

Enfys will work in tandem with PanCam – a camera system led by UCL’s Mullard Space Science Laboratory – to pinpoint mineral targets. These insights will enable the rover to select optimal drilling sites on the Martian surface, with samples analysed by other onboard instruments. The instrument being shipped today will be installed on the rover’s ‘Earth twin’ known as the Ground Test Model located at the Aerospace Logistics Technology Engineering Company in Turin.

Since the Franklin rover was initially supposed to launch in 2020, it is puzzling this instrument is only being delivered now. It could be that the original spectrometer was supposed to be provided by ESA’s original partner in the project Russia, but became unavailable when that partnership broke up due to Russia’s invasion of the Ukraine.

Or it could be the instrument’s development was simply late and behind schedule, as so many ESA’s projects routinely are. For example, the mission’s launch was first delayed from ’20 to ’22 because the parachutes weren’t ready. Then it was delayed until ’28 because of the break-up with Russia. Even now it remains uncertain it will meet this new date.

Faced with loss of the federal gravy train, Lowell Observatory makes major changes

8:58 am

According to a press release last week, the Lowell Observatory in Arizona is now making major changes to it management and operations due to “declines in federal research funding.”

The new framework centers on two defining pursuits: Planetary Defense, safeguarding our world from cosmic hazards, and Exoplanetary Research, seeking to understand distant worlds and the potential for life beyond Earth.

Declines in federal research funding, coupled with uncertainty about future national priorities, have impacted research institutions across the country. At the same time, Lowell’s historic reliance on internal funding to sustain research is no longer a viable long-term model. To ensure stability and growth, the Observatory will focus its efforts on key scientific areas while building new endowments to support the scientists and technology that drive discovery.

Essentially, it can no longer depend on easy federal cash (thank you Donald Trump!), and thus needs to actually do real research work in fields that others consider important. It will also abandon its “traditional academic tenure system.” Scientists who use the facility will now have to earn that right, in a case-by-case basis. And such researchers will have to be funded by “private, endowed support.”

In other words, Lowell is returning to the model that had been used by American researchers for most of the nation’s history, until World War II, getting their funding from private sources rather than the federal teat.

We should expect therefore the work at Lowell to become more effective and focused, something it has not been for decades.

Germany’s space agency DLR delivers one prototype leg for Europe’s Callisto grasshopper

8:45 am

Callisto's basic design
Callisto’s basic design

Government in-action: After a decade of work, the German space agency DLR this week finally delivered for testing a prototype leg of the Callisto grasshopper-type demo rocket, intended by the European Space Agency (ESA) to demonstrate vertical take-off and landing.

On 9 October, the Institute of Structures and Design announced that it had delivered a qualification model of the demonstrator’s landing leg to the Institute of Space Systems in Bremen. According to a 3 December 2024 update, the leg will now undergo a series of tests at the Institute’s Landing and Mobility Facility, including deployment, touchdown, and vibration testing.

Once the qualification test campaign is complete and the landing leg design has been validated, the Institute of Structures and Design will proceed with the construction of the four flight-ready legs.

Note again that Callisto, as shown to the right, was proposed as a joint ESA and JAXA project in 2015. Only now, a decade later, as DLR delivered one prototype leg. The first test hop has been repeatedly delayed, so that now it is now not expected to happen until 2027, and that rocket will not even be an operational version, it will simply be a small scale prototype.

Meanwhile, SpaceX has landed its Falcon 9 first stage hundreds of times, and reused them dozens of times. Other companies are flying or building their own reusable rockets, and hope to fly operational versions next year.

The contrast between this government project and the private sector is quite embarrassing. What makes it even more embarrassing is that it is par for the course, and yet so many people still look to the government as the god who can get things done. When will people learn?

Watch the eleventh orbital test flight of SpaceX’s Starship/Superheavy rocket

8:32 am

The eleventh orbital test launch of Starship/Superheavy is scheduled for 6:15 (Central) today. It will be the last flight for version 2 of Starship, and will also include the second reuse of a Superheavy booster.

Starship will repeat its flight plan from the previous flight, testing the deployment of dummy Starlink satellites, the relighting of its Raptor engines once in orbit, and various new configurations of its thermal protection system. It will come down in the Indian Ocean, either controlled or not. Future flights will use version three, and quickly move towards orbital flights and a return to Boca Chica for a tower chopstick capture and later reuse.

Superheavy, which flew previously on the eighth test flight, will do more engine configuration tests on its return, and will attempt a soft vertical splashdown in the Gulf.

Rocket Lab gets two-launch contract from Japan’s space agency JAXA

10:07 am

In what appears to be a significant slap at its own rockets (especially its delayed Epsilon-S rocket), Japan’s space agency JAXA this week signed a two-launch deal with the American rocket company Rocket Lab.

Launching from Rocket Lab Launch Complex 1 in New Zealand, the two Electron missions will deploy satellites for JAXA’s Innovative Satellite Technology Demonstration Program. The first launch, scheduled from December 2025, will deploy the agency’s RApid Innovative payload demonstration SatellitE-4 (RAISE-4) spacecraft, a single satellite that will demonstrate eight technologies developed by private companies, universities, and research institutions throughout Japan.

The second launch, scheduled for 2026, is a JAXA-manifested rideshare of eight separate spacecraft that includes educational small sats, an ocean monitoring satellite, a demonstration satellite for ultra-small multispectral cameras, and a deployable antenna that can be packed tightly using origami folding techniques and unfurled to 25 times its size.

Rocket Lab has previously won contracts from several private Japanese satellite companies (Q-Shu, Astroscale, ALE), but this I think is the first JAXA contract it has won. What makes it significant is that JAXA has always focused on using its own rockets, the large retired H2A and the new H3 as well as the smaller Epsilon-S. To go to an American company is somewhat unprecedented.

Though larger than Rocket Lab’s Electron rocket, Epsilon-S was being developed to compete for the same market. That development however has been plagued by failure, including explosions of engines during tests of both its upper and first stages in ’23 and ’24 respectively. After the second explosion JAXA announced in December 2024 the rocket’s first launch would not occur in the spring of 2025 as planned, but provided no additional information. Since then there have been no updates.

This Rocket Lab deal suggests the Epsilon program is in big trouble. In the long run however this might be a very good thing for both JAXA and Japan’s own nascent rocket industry. JAXA might finally be recognizing that building and owning its own rockets is not the best plan, that it would be better to use the capitalism model and simply be a customer buying the services from the private sector. At the moment Japan doesn’t yet have a viable commercial rocket sector, with only Mitsubishi having an operational commercial rocket, the H3 (mostly controlled by JAXA). There are a number of new startups however, including Interstellar, Honda, Space One, and Tispace, all of which have done tests of one kind or another. If JAXA is ready to abandon its own government rockets and buy the service from the private sector, those Japanese startups will start to prosper.
