SpaceX launches 28 Starlink satellites, reuses 1st stage for 29th time

8:31 am

SpaceX last night successfully launched another 28 Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg Space Force Base in California.

The first stage, B1071, completed its 29th flight, landing on a drone ship in the Pacific. The present rankings for the most reflights of a rocket:

39 Discovery space shuttle
33 Atlantis space shuttle
30 Falcon 9 booster B1067
29 Falcon 9 booster B1071
28 Columbia space shuttle
28 Falcon 9 booster B1063
27 Falcon 9 booster B1069

Sources here and here.

Note also that SpaceX was able to refly this stage only 24 days after its previous flight. Even after 28 flights, the booster appears so robust the company can get it back in the air only weeks later.

The leaders in the 2025 launch race:

129 SpaceX
58 China
13 Russia
12 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 129 to 98. SpaceX has another launch scheduled for this evening, placing another set of Amazon’s Kuiper satellites into orbit.

Japanese satellite company extends its launch contract with Rocket Lab

8:01 am

The Japanese satellite company Q-shu Pioneers of Space, Inc. (iQPS) has purchased three more launches from Rocket Lab, for a total of seven planned.

The multi-launch contract includes three dedicated Electron missions that will launch no earlier than 2026 from Rocket Lab Launch Complex 1 in New Zealand. With four dedicated missions already booked by iQPS on Electron, these three additional missions bring the total number of upcoming launches for iQPS to seven.

Each dedicated launch will deploy a single synthetic aperture radar (SAR) satellite from a Rocket Lab Motorized Lightband separation system – demonstrating Rocket Lab’s vertical integration across launch and space systems that improves reliability and streamlines the launch process for its customers.

Rocket Lab has already completed four successful launches for iOPS, so with this deal means that it will complete eleven launches total for the satellite company. Essentially iQPS has made Rocket Lab its prime launch provider.

This is also the second major launch contract for Rocket Lab in the past week. On September 30, 2025 Synspective purchased its second multi-launch contract with the company, buying ten more launches. Its first contract was for eleven launches, with six already completed. Synspective hopes to have its entire radar constellation of 30 satellites in orbit by the late 2020s.

Both contracts tell us that Rocket Lab’s Electron rocket is going to have a very busy launch schedule for the next few years, even as the company initiates its larger Neutron rocket.

  • SpaceX registers the trademark “Starfall” at the U.S. Patent Office
    No real information beyond that. The tweet adds this tantalizing tidbit, stating that this action is “through the island nation of Tonga covering: launch, on-orbit, and reentry services, spaceflight travel, in-space manufacturing services, custom manufacturing & processing of pharmaceuticals.” Tonga is east of Australia in the Pacific. Is SpaceX planning Starship landings there?

Is the fate of the independent live streams in Boca Chica uncertain?

12:52 pm

My headline paraphrases this interesting, very detailed, and largely accurate article today from Texas Monthly. It outlines how the newly formed town of Starbase there has the power to block the many independent lives streams and tourist operations that have sprung up since SpaceX opened its facility in Boca Chica.

This proxy government also has the power to create zoning rules and enforce them. In July the city adopted a plan that leaves those with the closest views of the launchpads in violation of new zoning designations. The mainstay launch-day ticket sellers here—Rocket Ranch and a few others—operate in what’s now officially a residential area, near newly built homes for SpaceX executives. The same violation applies to the spots where the streamers have mounted their video cameras.

These cottage industries aren’t doomed. Texas law has grandfathering provisions that allow existing businesses to remain open after zoning changes. But Starbase city attorney Andy Messer raised eyebrows during a recent city commission meeting by saying that the grandfathering would be considered on a “case-by-case basis.” Hearing this, some property owners expressed hesitation to approach the city to ask if their status was in question. “I don’t want to poke the bear,” as one put it.

Will SpaceX force the town of Starbase to shut these independent operations down? The article describes the possibilities in great detail. The very nature of SpaceX and its founder, Elon Musk, suggests it won’t happen. The company thrives on openness and straight talk. Musk himself is a proven supporter of free speech and competition. It would be shocking if his company suddenly took a different position. Moreover, SpaceX, Starbase, or its residents (almost all of which are SpaceX employees) generally benefit from the good publicity of these independent operations, publicity that the company’s own employees enjoy.

Yet, Starbase is a company town, and the long history of such places is that with time, the company takes over and rules everything, allowing nothing that it does not control.

Stay tuned. Above all things won’t be dull in Boca Chica.

Martian boxwork on the flanks of Mount Sharp

The boxwork on Mars
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 5, 2025 by the left navigation camera on the Mars rover Curiosity.

The picture looks north and downhill from the lower flanks of Mount Sharp, inside Gale Crater. In the far distance on the horizon can be seen the crater’s northern rim, about 20 to 30 miles away. As it is now moving into the dusty season on Mars, the haze has increased from only a month ago, making it hard to see many distant details.

In the foreground can be seen clearly the light-colored ridges of the boxwork that the rover has been traversing for the past three months, with one rover track visible on the nearest ridge. Unlike the very rocky and boulder-strewn terrain the rover has seen in most of its travels on Mount Sharp, this boxwork seems smoother.

The Juno mission at Jupiter is almost certainly over

8:52 am

An article yesterday at Space.com speculated that the Juno mission to Jupiter is likely over, but added that we cannot yet be sure because the government shutdown has prevented NASA from making any definitive announcement.

NASA’s management had previously extended the orbiter’s mission several times, with the last extension going until the end of the 2025 fiscal year, that ended on September 30, 2025. No new budget has yet been approved, and the proposed Trump budget had included no money for extending the mission farther.

Due to the government shutdown, NASA is currently unable to say whether Juno is still operating or already powered down. At the time of publication, responses from agency officials state that “NASA is currently closed due to a lapse in government funding … Please reach back out after an appropriation or continuing resolution is approved.”

Under shutdown rules, only missions that fall under “excepted activities” — those required to protect life, property, or national security — can continue operations or communications. NASA’s continuity plans also specify that carryover funding may only be applied to “presidential priorities,” which limits what science programs can proceed during a lapse.

Juno does not fall into those protected categories, and was also zeroed-out on the President’s fiscal year 2026 budget request — making the mission, presumably, not a priority. So, until normal government operations resume, the spacecraft’s future is uncertain.

I think Juno’s future at this point is not uncertain in the least. While other active missions that the Trump proposed shutting down might get revived, Juno is unlikely to be one of them. I suspect the science team has put it in hibernation, and is already beginning to move on to other projects and work. They are being coy about this in the faint hope Congress will save Juno, but this should not be a priority. At this point I think NASA would be wiser to spend its resources elsewhere.

The left only has a short window remaining to stop its violence before the hammer strikes it hard

5:20 pm

Cry havoc!

So there is no confusion, my headline is not something I advocate. It is merely what seems inevitable when a law abiding society — America — has within it a subculture (the modern left led by the very corrupt and power-hungry Democratic Party) that thinks it is not only above the law, but its ideology justifies all kinds of violence. To wit, there’s this post today by Guy Benson, nicely summarizing only a small selection of recent leftist violence. I quote it in full, because this is necessary to get the feel of reality:

I’d like to ask my non-conservative followers to pay attention here for a moment. I don’t need a response or a rebuttal or a ‘whatabout.’ Just read on and consider what I’m saying. Please.

We are only a few weeks removed from a leading conservative figure being shot in the throat and killed by a leftist, for and during his speech, at a public speaking event. Stunning, jarring numbers of leftist Americans justified or celebrated this assassination, aligning with multiple public polls showing that a sizable minority of leftists in this country think political violence can be acceptable.

Today — just today — many conservatives are thinking about:

(1) a major leftist statewide candidate being exposed for sending texts to a political opponent (R) explicitly hoping for the death of another conservative political opponent…along with the deaths of that opponents’ young children. He WROTE DOWN that the pain of those deaths might promote his own agenda, which would be worth it, in his estimation. This candidate is now condemning his current conservative opponent for noticing this information.

A galaxy with a starburst ring within its nucleus

A galaxy with a starburst ring
Click for full image.

Cool image time! The picture to the right, cropped, reduced, sharpened, and annotated to post here, was released today by the science team of the Hubble Space Telescope as the picture of the week. This crop focuses on the central regions of this barred spiral galaxy, about 70 million light years away, with an unusual extra feature, a starburst ring encircling its nucleus. From the caption:

NGC 6951’s bar may be responsible for another remarkable feature: a white-blue ring that encloses the very heart of the galaxy. This is called a circumnuclear starburst ring — essentially, a circle of enhanced star formation around the nucleus of a galaxy. The bar funnels gas toward the centre of the galaxy, where it collects in a ring about 3800 light-years across. Two dark dust lanes that run parallel to the bar mark the points where gas from the bar enters the ring.

The dense gas of a circumnuclear starburst ring is the perfect environment to churn out an impressive number of stars. Using data from Hubble, astronomers have identified more than 80 potential star clusters within NGC 6951’s ring. Many of the stars formed less than 100 million years ago, but the ring itself is longer-lived, potentially having existed for 1–1.5 billion years.

This galaxy has also seen about a half dozen supernova, which raises the question: Does intense star formation trigger more supernovae? That is a question that can’t be answered with the data presently available.
