SpaceX launches 29 more Starlink satellites, sets new record for Falcon 9 reuse, dominates the world in rocketry
First stage after landing for the 32nd time
SpaceX today launched another 29 Starlink satellites, its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida.
The first stage of its Falcon 9 rocket (B1067) flew for its 32nd time, a new record for a Falcon 9 first stage. As shown in the rankings below of the most reused launch vehicles, this stage is now just one flight from tying the space shuttle Atlantis:
39 Discovery space shuttle
33 Atlantis space shuttle
32 Falcon 9 booster B1067
30 Falcon 9 booster B1071
29 Falcon 9 booster B1063
28 Falcon 9 booster B1069
28 Columbia space shuttle
Nor will it be long before SpaceX’s fleet surpasses all the shuttles.
Meanwhile in the 2025 launch race SpaceX’s dominance is overwhelming, as shown by the leader board:

Astronomers detect a seven-hour-long gamma ray burst, the longest many times over
Astronomers have detected the longest gamma ray burst (GRB) ever measured, lasting more than seven hours when most GRBs at most last mere seconds.
The image to the right was taken by the Hubble Space Telescope and is taken from figure 1 of the peer-reviewed paper [pdf]. The two hash marks indicate the location of the GRB, within the outer reaches of its host galaxy and inside one of its spiral arms, based on other data. The data also suggested the host galaxy is “massive [100 billion solar masses], dusty, and [an] extremely asymmetric system that is consistent with two galaxies undergoing a major merger.”
The GRB’s long length means that none of the known theories for its origin work. From the press release:
Of the roughly 15,000 GRBs observed since the phenomenon was first recognized in 1973, only a half dozen come close to the length of GRB 250702B. Their proposed origins range from the collapse of a blue supergiant star, a tidal disruption event, or a newborn magnetar. GRB 250702B, however, doesn’t fit neatly into any known category.
From the data obtained so far, scientists have a few ideas of possible origin scenarios: (1) a black hole falling into a star that’s been stripped of its hydrogen and is now almost purely helium, (2) a star (or sub-stellar object such as a planet or brown dwarf) being disrupted during a close encounter with a stellar compact object, such as a stellar black hole or a neutron star, in what is known as a micro-tidal disruption event, (3) a star being torn apart as it falls into an intermediate-mass black hole — a type of black hole with a mass ranging from one hundred to one hundred thousand times the mass of our Sun that is believed to exist in abundance, but has so far been very difficult to find. If it is the latter scenario, this would be the first time in history that humans have witnessed a relativistic jet from an intermediate mass black hole in the act of consuming a star.
None of these proposed explanations are confirmed. What is known is that this GRB was unique in all ways, defying all theoretical expectations.

- On this day in 1985, NASA transferred title of the engineering test space shuttle Enterprise to the Air & Space Museum
It was on display at the Udvar-Hazy Center from 2003 until 2012, then moved to the Intrepid Museum in New York when the shuttle Discovery replaced it.
- On this day in 1995 Galileo arrived at Jupiter, the first spacecraft to orbit the planet
Because its high gain antenna never unfolded, the data stream from the spacecraft was severely limited. Despite this, Galileo did provide us a good first look at Jupiter’s main moons and their strange unexpected surfaces.
Now available in hardback and paperback as well as ebook!
From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

The war-mongers are always those in power
After Diane and I recently watched Mel Gibson’s movie Braveheart I was intrigued to find out the real history behind William Wallace and the war between Scotland and England in the 1200-1300s. Fortunately, I stumbled upon Ronald McNair Scott’s excellent 1982 history, Robert the Bruce, King of Scots.
Not surprisingly, I learned that William Wallace played a relatively minor role in the effort of the Scots to break free from English rule than implied by the movie. The movie was reasonably accurate overall, but the real leader of that long battle was Robert the Bruce, who was descended from previous rulers and fought a long guerilla war against multiple English kings over more than three decades to establish his nation’s independence and his right to rule as king.
That fight began after the death of Scotland’s previous king, Alexander III in 1286. Alexander had for years maintained a peaceful alliance with England, as two separate nations. The problem was that when he died, his heir was still a child. His regents signed a deal with the English king, Edward I, allowing them to rule an independent Scotland as allies with England, but Edward soon realized the power vacuum in Scotland provided him an opportunity. He repudiated the treaty and began a long violent effort to conquer these northern provinces.
The result was thirty years of endless war, ravaging the countryside both in Scotland and northern England. Eventually Robert the Bruce won, getting England to acknowledge the independence of Scotland. Thus Bruce in many ways is seen as Scotland’s own version of George Washington.
What struck me as I read this book however was the plunder and devastation this long war visited upon the ordinary people in both England and Scotland. Edward would invade Scotland, wrecking havoc on local villages and castles. Bruce would respond with repeated raids into northern England, where he would destroy villages and farms, leaving the surviving inhabitants to starve.
And what was the war about?

A small galaxy with lots of massive stars
Click for original image.
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope and released this week as the European Space Agency’s (ESA) Hubble picture of the week.
This dwarf galaxy, 13 million light years away, is called Markarian 178 (Mrk 178). Though much smaller than the Milky Way, it is packed with massive stars. From the caption:
While the bulk of the galaxy is blue owing to an abundance of young, hot stars with little dust shrouding them, Mrk 178 gets a red hue from a collection of massive stars, which are especially concentrated in the brightest, reddish region near the galaxy’s edge. This azure cloud is home to a large number of rare objects called Wolf–Rayet stars. Wolf–Rayet stars are massive stars that are casting off their atmospheres through powerful winds. Because Mrk 178 contains so many Wolf–Rayet stars, the bright emission lines from these stars’ hot stellar winds are etched upon the galaxy’s spectrum. Particularly ionised hydrogen and oxygen appear as a red colour to Mrk 178 in this photo, observed using some of Hubble’s specialised light filters.
Massive stars enter the Wolf–Rayet phase just before they collapse into black holes or neutron stars. Because Wolf–Rayet stars last for only a few million years, researchers know that something must have triggered a recent burst of star formation in Mrk 178. At first glance, it’s not clear what could be the cause — Mrk 178 doesn’t seem to have any close galactic neighbours that could have stirred up its gas to form new stars. Astronomers believe that it was triggered by the interaction with a smaller satellite, as revealed by the presence of low surface brightness tidal features detected around Mrk 178 in deep imaging acquired with the Large Binocular Telescope.
And yet, these observations do not see this small satellite galaxy. It has either been completely absorbed into Mrk 178, or maybe this theory for explaining this dwarf galaxy’s make-up is flawed.

More than 300 companies in discussions in connection Space Force’s “Golden Dome” project
According to guarded remarks by the head of Trump’s “Golden Dome” project, he has been in negotiations with more than 300 aerospace companies as the Space Force begins preliminary design work on this missile defense system.
President Trump’s Golden Dome czar says he has held “one-vs.-one” talks with more than 300 private companies in recent months to hash out the secretive architecture of the futuristic missile defense shield that the administration is determined to put into operation over the entire U.S. homeland by mid-2028.
In his first public remarks since being named to the position in June, Gen. Michael A. Guetlein, vice chief of space operations at the U.S. Space Force, told an audience at the annual Reagan National Defense Forum that although the layered design of the Golden Dome remains classified, he is confident that “our industry partners have a pretty good insight into what we’re doing.”
The project, which remains mostly cloaked in secrecy, received $24.5 billion in funding this year from Congress, with that number expected to rise considerably in later years.
My sense from Guetlein’s remarks is that right now the project is simply gathering already existing missile defense assets under one roof in order to get something operational by 2028 as ordered by Trump. Guetlein is also getting the enthusiastic support of the industry — which sees big bucks flowing their way from Golden Dome in the coming years. Many of the new space startups have been shifting operations from civilian space to this military project in anticipation of this funding.
While the concept is not unreasonable, considering the success seen with the Pentagon’s Patriot system and Israel’s Iron Dome, the secret structure so far of Golden Dome is almost guaranteed to lend itself to corruption and wasteful spending, a systemic problem within our present federal government.
Korean Air and Hyundai Rotem sign deal to develop methane-fueled rocket engine
Two South Korean companies, the airline company Korean Air and the railroad company Hyundai Rotem, have signed a partnership agreement to develop a methane-fueled rocket engine by 2030, funded by the government’s Korea Research Institute for Defense Technology Planning and Advancement (KRIT).
Korean Air will lead the development of the engine’s turbopump, a core component often described as the heart of the propulsion system. The turbopump compresses liquid methane and oxidizer at extremely high pressures and speeds. Its development requires advanced engineering capable of handling cryogenic temperatures of -180°C to several hundred degrees, while rotating tens of thousands of times per minute.
Hyundai Rotem is a division of the automobile company Hyundai, but its focus is building railroads. The press release does not say what it will do as part of this partnership.
It is also unclear from the press release whether these companies will be own this engine for sale to others, or are developing it for the government. If the latter, the project will have a much more limited potential.
Japanese startup Ispace expands deal with Japan Airlines
The Japanese lunar lander startup Ispace has now expanded its partnership deal with Japan Airlines (JAL) and two other associated JAL companies aimed at building transportation infrastructure to, from, and on the Moon.
The new agreement outlines the co-creation of systems and infrastructure supporting future lunar bases with high-frequency transportation to the lunar surface. Leveraging maintenance technology, air traffic control, and operations management expertise developed by JAL and JALEC in the aviation field, the two companies will aim to advance a sustainable presence on the Moon.
With the addition of JALUX to the partnership, the companies will explore new collaborations regarding space-related services for the public within the JAL Group. Consideration will also be given to sales cooperation for payloads sales utilizing ispace’s lunar transportation service. By combining ispace’s lunar transportation via its lander with the JAL Group’s aviation expertise and customer network, the partnership is expected to provide lunar transportation opportunities to diverse stakeholders.
A lot of vague PR language, but it does appear the goal is to develop lunar transportation products for what the companies expect to be a growing industry on the Moon.
Russia and India agree to orbit their space stations in the same inclination, the same as ISS
India’s Bharatiya Antariksh Station as outlined in 2024.
Click for original image.
According to statements made by Roscosmos head Dmitry Bakanov at a conference in New Delhi this week, Russia and India have agreed to orbit their planned new space stations in the same inclination as ISS, 51.6 degrees, and coordinate their operations at both stations.
By choosing the same orbital geometry for ROS [Russian Orbital Station] and BAS [Bharatiya Antariksh Station], Moscow and New Delhi are effectively planning a continuous “replacement belt” in low Earth orbit. After the ISS is retired, crewed spacecraft launched from Russia and India would still be able to reach a major laboratory complex without radically changing launch trajectories or infrastructure, and—crucially—could, in principle, travel between the two stations with relatively modest maneuvers compared with a full plane-change.
Bakanov’s New Delhi comments build on a broader Roscosmos–ISRO understanding that the two stations should be able to support cross-visits, resource sharing and coordinated operations once both are flying.
This high inclination is required because spacecraft launching from Russia’s high latitudes can’t reach lower inclinations practically. India could put its station at a lower inclination (being at a lower latitude), but if this story is true, it apparently has decided there are advantages using an orbit that will allow cross-missions with Russia, including launches from Russia.
India plans to launch the first module of its station in 2028, and have the entire station operational by 2035. Russia says it will launch is station’s first module by 2027, with full operations beginning by 2030. While both schedules are likely to see delays, we should expect India to get its station built, while Russia will likely struggle to launch even one module.
In fact, I suspect this deal is Russia’s effort to find some partner that can carry it in the future, when its own station gets delayed.

My November fund-raising campaign for Behind the Black is now over. As I noted at the start of the campaign, up until October 2025 had been a poor year for donations. This campaign changed that, drastically. November 2025 turned out to be the most successful fund-raising campaign in the fifteen-plus years I have been running this webpage. And it more than doubled the previous best campaign!
Words escape me! I thank everyone who donated or subscribed. Your support convinces me I should go on with this work, even if it sometimes seems to me that no one in power ever reads what I write, or even considers my analysis worth considering. Maybe someday this will change.
Either way, I will continue because I know I have readers who really want to read what I have to say. Thank you again!
This post will remain at the top of the page for the next few days, to make sure everyone who donated will see it.
