Review of SpaceX’s 2026 Superheavy/Starship test flights

11:22 am

Link here. The article begins by reviewing the work SpaceX is doing at both Boca Chica in Texas and Cape Canaveral in Florida. In the end, the company is aiming to have two Starship launchpads at Boca Chica and three launchpads in Florida, with both locations have extensive manufacturing facilities capable of building ships and boosters almost continually.

It then provides a nice review of all five Superheavy/Starship test flights that took place in 2025, a review that makes it very clear how much was accomplished, and indicates the possibilities for ’26. If SpaceX could manage almost one flight every two and a half months last year, despite two test stand explosions, the odds are excellent it will exceed that pace this year.

SpaceX launches 29 more Starlink satellites, plus a review of its Falcon 9 first stage fleet

12:10 am

The beat goes on: SpaceX tonight successfully launched another 29 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

This was SpaceX’s second launch in 2026. At this moment the company is the only one to have launched anything this year.

The rocket’s first stage was on its first flight, landing successfully on a drone ship in the Atlantic. As new boosters are now introduced so rarely, I decided to look back at how many new stages SpaceX has been introducing each year to get a sense of the size of its fleet. The rough chart below is based on the data on this Wikipedia page. It begins in 2018 because that is when SpaceX introduced the Block 5 version of the stage that it still uses, and says is designed to do as many as 40 flights.

New stages introduced each year:
—————————————–
2018: 6 (all now deactivated or expended)
2019: 7 (all now deactivated or expended)
2020: 4 (all now deactivated or expended)
2021: 3
2022: 7 (5 deactivated or expended)
2023: 9 (5 deactivated or expended)
2024: 9 (3 deactivated or expended)
2025: 8

According to that webpage, SpaceX has approximately 25 active stages in its fleet. The numbers above suggest the company has been increasing the size of its fleet steadily. In fact, since 2022 it appears the company has added 23 stages to the fleet. In 2025 it appears it added a new stage about every 20 launches.

This estimate is rough and is almost certainly not precisely accurate. For example, several stages listed as active have flown only once, or have not flown in awhile.

Nonetheless, this rough count helps explain how SpaceX can launch so frequently. It now has a robust fleet of Falcon 9 boosters to draw on, and it is growing that fleet to meet its needs. All it needs to do is make sure it can manufacture enough upper stages and satellites to fill its launch manifest.

NASA: The leak in the Zvezda module on ISS has apparently been sealed

10:51 am

According to one NASA official, the leaks in the Zvezda module on ISS that have been on-going for more than five years have apparently all been sealed.

However, recently two sources indicated that the leaks have stopped. And NASA has now confirmed this. “Following additional inspections and sealing activities, the pressure in the transfer tunnel attached to the Zvezda Service Module of the International Space Station, known as the PrK, is holding steady in a stable configuration,” a space agency spokesman, Josh Finch, told Ars. “NASA and Roscosmos continue to monitor and investigate the previously observed cracks for any future changes that may occur.”

While good news, no one should feel sanguine. The leaks occurred because the hull of Zvezda has developed stress fractures, due to age (more than a quarter century in orbit) and the repeated dockings to its aft port. Future fractures and leaks are still possible, with the chance of a catastrophic failure very possible.

It would be prudent for NASA to continue to shut the hatch between the U.S. and Russian halves of the station, whenever a docking is taking place.

India’s space agency: At least six launches in 2026

10:42 am

According to remarks by the head of India’s space agency ISRO last week, the agency is planning at least six launches in 2026, including two unmanned test flights of its Gaganyaan manned capsule.

Also planned will be the first launch of its PSLV rocket that was manufactured entirely by commercial vendors, rather than ISRO itself. The goal by the Modi government had been to transfer ownership of the rocket to private companies, but ISRO revised that to retain control and ownership while giving manufacture to the private companies HAL & L&T, thus defeating the essential goal of shifting power to the private sector.

The total does not include possible orbital attempts by two rocket startups, Skyroot and Agnikul.

Conscious Choice cover

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.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

SpaceX completes first launch in 2026

12:36 am

The beat goes on! SpaceX tonight successfully placed an Italian Earth observation satellite into orbit, its Falcon 9 lifting off from Vandenberg Space Force Base.

The satellite’s data will be used by Italy for both military and civil purposes. The rocket’s first stage completed its 21st flight, landing back at Vandenberg. The two fairings completed their 2nd and 23rd flights respectively.

At this moment, SpaceX has the only launch in 2026.

Many Martian mysteries in one spot

11:29 am

Many Martian mysteries in one spot
Click for original image.

Just because there are no new images coming back from Mars at this time because the Sun is in the way does not mean we can’t enjoy more cool Martian images. The picture to the right, cropped, reduced, and sharpened to post here, was taken on October 20, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Labeled merely a “terrain sample,” this means it was taken not as part of any particular research project but to fill a gap in the camera’s schedule. The camera team needs to take regular photographs in order to maintain the camera’s proper temperature, and when there is a long gap they add a terrain sample image to the schedule. Usually they try to pick some target of interest.

In this case the target is this 2,500-foot-high cliff, in which we can see a whole range of Martian geological mysteries. First there are the slope streaks on the cliff, a feature unique to Mars but as yet unexplained. Resembling avalanches, these streaks leave no debris piles at their base, do not change the topography in any way, and can appear randomly throughout the year, fading with time. Though the streaks in this picture are dark, streaks can also be bright.

Both the parallel ridges at the base of the cliff, as well as the cliff itself, are remnants of other major geological events, at least based on present theories.

SpaceX doing trial runs of specialized barge for transporting Starship/Superheavy from Boca Chica to Florida

9:32 am

SpaceX has now confirmed that it is doing trial runs of a barge specifically designed for transporting Starship/Superheavy from the manufacturing facility in Boca Chica to its Florida launchpads.

[SpaceX’s Vice President of Launch, Kiko] Dontchev also clarified that both the Super Heavy booster and Starship upper stage would be tilted to a horizontal position for maritime transit, in response to an artist’s rendering of a Starship traveling vertically aboard a vessel. “Initial deliveries are a single booster or ship per trip, with the plan to move to multiple vehicles per transit sooner than later,” he wrote. “You’ll thank me later.”

These barge trials, combined with the fact that SpaceX has already shipped significant Starship/Superheavy components to Florida even as it builds rocket manufacturing facility there, strongly suggest the first Florida launches are not too far in the future, possibly even this year.

ESA funds Danish lunar orbiter

9:16 am

The European Space Agency (ESA) has agreed to fund the first Danish-built interplanetary probe, a smallsat lunar orbiter dubbed Mani that will launch in ’29 and map the Moon’s surface.

The Máni mission is a lunar mission that will use a satellite to map the Moon’s surface with high-resolution images and create detailed 3D maps. The goal is to make it safer for astronauts and lunar rovers to land and move around on the Moon. The satellite will orbit the Moon’s north and south poles, which are key areas for future human missions.

The mission will also map how light reflects from areas on the Moon that are used to study Earth’s ability to reflect sunlight onto the lunar surface – the so-called earthshine. This knowledge could improve our understanding of how Earth’s climate will evolve.

The University of Copenhagen leads the mission and is responsible for the mission’s Science Operations Center, which will plan which areas to map and analyze the vast number of images generated.[emphasis mine]

I love how this European press release about a lunar orbiter somehow makes its most important mission studying climate change on Earth. Utterly idiotic.

Mani will use the changing shadows to create detailed topographic maps. As it is unlikely it will be capable of providing better data than produced over the past sixteen years by Lunar Reconnaissance Orbiter (LRO), this mission is mostly an engineering demo by Denmark and the Danish startup, Space Inventor, that is building the satellite for a consortium of universities. If successful the satellite will possibly be able to replace LRO (which is going to fail sooner or later), and provide data on any lunar surface changes that occur in the future.

SpaceX to do a major orbital reconfiguration of its Starlink constellation

9:03 am

According to a X post yesterday by Michael Nicholls, SpaceX’s Starlink engineering vice-president, the company over the next year will be lowering the orbits of more than 4,000 satellites in its Starlink constellation, in order to allow the company to more quickly de-orbit them if they fail.

We are lowering all Starlink satellites orbiting at ~550 km to ~480 km (~4400 satellites) over the course of 2026. The shell lowering is being tightly coordinated with other operators, regulators, and USSPACECOM.

Lowering the satellites results in condensing Starlink orbits, and will increase space safety in several ways. As solar mininum approaches, atmospheric density decreases which means the ballistic decay time at any given altitude increases – lowering will mean a >80% reduction in ballistic decay time in solar minimum, or 4+ years reduced to a few months. Correspondingly, the number of debris objects and planned satellite constellations is significantly lower below 500 km, reducing the aggregate likelihood of collision.

Nicholls notes that it presently has only two dead satellites in the present fleet of 9,000 satellites, but decided to do this move regardless, as it also apparently will reduce collision risks with other satellites as well.

Not surprisingly, China’s state-run press and our anti-capitalism propaganda press immediately tried to give China credit for this change, while lambasting SpaceX. That China is contributing to the risk of collision with its own multiple giant satellite constellations and is doing nothing on its own is apparently irrelevant to both. Our nice of them.

The three week communications blackout from Mars has begun

11:30 am

Last image before blackout from Curiosity
Click for original.

Last image before blackout from Perseverance
Click for original.

The two images to the right, both downloaded today (here and here) from the Mars rovers Curiosity (top) and Perseverance, illustrate quite clearly the beginning of the three-week-long communications blackout from Mars caused every two years when the orbits of Earth and Mars places the Sun in-between. As the Curiosity science team noted in a December 22, 2025 update:

This holiday season coincides with conjunction — every two years, because of their different orbits, Earth and Mars are obstructed from one another by the Sun; this one will last from Dec. 27 to Jan. 20. We do not like to send commands through the Sun in case they get scrambled, so we have been finishing up a few last scientific observations before preparing Curiosity for its quiet conjunction break.

Apparently engineers were able to squeeze data and images from Mars for a few extra days, but the incomplete nature of these two pictures — combined with the lack of any other new images today — tells us that the blackout has definitely begun. That they were able to get these additional images after conjunction began suggests the blackout might also end a bit earlier than expected.

Though there is always a concern that something could go wrong while communications are blocked, the risks are small. The science teams for all the Mars orbiters and rovers have dealt with this situation now almost a dozen times since operations became routine there more than a quarter century ago.

The only spacecraft at real risk this conjunction is Maven. Contact was lost from it in early December for unknown reasons, and all efforts to regain communications have so far failed. All engineers know from the little data they have gotten back is it appears to be tumbling. This three week blackout will make any chance of recovery extremely unlikely.

The global launch industry in 2025: The real space race is between SpaceX and China

8:01 am

In 2025 the worldwide revolution in rocketry that began about a decade ago continued. Across the globe new private commercial rocket companies are forming, not just in the United States. And across the globe, the three-quarters-of-a century domination by government space agencies is receding, though those agencies are right now pushing back with all their might to protect their turf.

Dominating this revolution in 2025 in every way possible however were two entities, one a private American company and the second a communist nation attempting to imitate capitalism. The former is SpaceX, accomplishing more in this single year than whole nations and even the whole globe had managed in any year since the launch of Sputnik. The latter is China, which in 2025 became a true space power, its achievements matching and even exceeding anything done by either the U.S. or the Soviet Union for most of the space age.

Archeologists find what they think is evidence of fire-making by early Neanderthals

10:20 am

Archeologists have found a Neanderthal campsite from 400,000 years ago that shows strong evidence of the ability to make fire.

The researchers found two fragments of pyrite, a mineral that can produce sparks when struck against flint, indicating that the early Neanderthals used them as “a fire-making kit.” These ancient deposits mark the earliest known evidence of fire-making, roughly 400,000 years ago.

…The Barnham site lies in a disused clay pit in Suffolk, UK, preserving traces of the period around 427,000 to 415,000 years ago. In this area, the team found a small patch of reddened sediment, about the size of a modest campfire, surrounded by two pyrites, 19 flints, and four broken hand axes, showing clear signs of heating. Pyrites are rare locally, and the early Neanderthals likely carried them in from elsewhere.

Previously, the earliest known evidence of the ability to make fire had been dated from 50,000 years ago, and was done by homo sapiens, not Neanderthals.

Analysis of the sediment said the heat there matched that of a campfire, not a wildfire. The data also said the spot had been used repeatedly.

This one campsite suggests Neanderthals in general had the knowledge and tools to make fire, but it also could simply show the work of one particularly smart Neanderthal.

Turkey and Somalia confirm spaceport plans

9:14 am

Somalia

In a public meeting of the presidents of Turkey and Somalia in Istanbul yesterday, Turkish President Recep Erdogan confirmed that Turkey has begun construction of a spaceport in Somalia.

Astrophysicist Umut Yildiz said the project, announced by President Recep Tayyip Erdogan and detailed by Industry and Technology Minister Mehmet Fatih Kacir, offers Türkiye significant geographic and technological opportunities.

…President Erdogan said the first phase of the three-stage project has been completed and construction has begun under the Türkiye Space Agency, adding that the goal is to establish significant infrastructure in space launch and satellite technologies.

Minister Kacir said the spaceport will become a strategic, revenue-generating infrastructure for Türkiye through growing commercial satellite launch services, testing activities and integration processes, while also contributing to Somalia’s development.

This spaceport plan had first been revealed by Turkish officials two weeks ago, but yesterday’s press conference now makes it official.

No press release from Turkey’s state-run press however revealed the spaceport’s precise location in Somalia. Nor is it confirmed that any actual construction has begun. I suspect it will be a very long time before anything actually launches from the site.

Space Force requests proposals for new Vandenberg launchpad for heavy and super-heavy rockets

8:07 am

Vandenberg Space Force Base

The Space Force on December 29, 2025 released a request for information (RFI) from the private sector for building a new launchpad at the southern-most tip of Vandenberg Space Force Base, for use by “new” heavy and super-heavy rockets.

The Space Force said it prefers to use the site for new vehicles rather than ones that already have launch sites at Vandenberg, to “increase launch diversity” at the base. The service is also interested in vehicles with “unique capabilities,” such as point-to-point transportation or the ability to return payloads.

The RFI emphasizes the need for “technically mature” vehicles capable of operating from SLC-14 within five years of signing a lease agreement. Companies must also provide details about their operations to address safety concerns and minimize impacts on other launch operators at the base.

You can read the actual RFI here. The map to the right, taken from the RFI and annotated to post here, labels the area under consideration as “Sudden Flats”. SpaceX’s two launchpads are indicated, with SLC-6 presently under development.

Though the description of the request appears to favor SpaceX, it could also apply to Blue Origin’s New Glenn as well as the company’s proposed larger versions of that rocket.

The request asks for proposals within 30 days.

China launches two satellites for “new technology verification for space target detection”

7:55 pm

China today successfully launched two technology test satellites designed to do “space target detection”, its Long March 7A rocket lifting off from its coastal Wenchang spaceport.

China’s state-run press provided no other information. It also appears the drop zones for the rocket’s lower stages were once again in Philippino waters, requiring that government to warn its citizens to avoid those zones and subsequent any rocket debris.

The leaders in the 2025 launch race:

168 SpaceX
90 China (a new record)
18 Rocket Lab
17 Russia

SpaceX still leads the rest of the world in successful launches, 168 to 150.

At this moment no other launches are scheduled before the end of the year, thus closing out the 2025 year in rocketry. I will publish my annual global report in the next few days. Stay tuned.

The up and down tale of two rocket startups, Vector and Phantom

11:01 am

Jim Cantrell and cars
Jim Cantrell at Vector in 2017, shown in front of
one of his side businesses, fixing and refurbishing race
cars and rare luxury sports cars (located then at Vector).

The tales of rocket startups are often fraught with ups and downs of all kinds, often traveling in circles that no one can ever predict. This is one such tale.

In the mid-2010s there was a rocket startup called Vector, based here in Tucson, founded by a guy named Jim Cantrell. At that time Cantrell pushed the company in the style of Elon Musk, going very public for publicity and to raise investment capital.

He was remarkable successful at both. Unfortunately, his engineers were not as successful at engine building. After years of effort they all realized that their rocket engines were under-powered, and wouldn’t be able to get the rocket into orbit. In 2019 the company’s biggest investor backed out, Cantrell left the company, and new owners took over, hoping to rebuild.

Flash forward to 2021, and Jim Cantrell has reappeared with a new rocket company, Phantom Space, also based in Tucson, raising $6 million in seed capital. In the next four years he obtained a small development contract from NASA, completed two more investment rounds raising first $22 million and then around $37 million, and began development of a new orbital rocket, dubbed Daytona. The company also began work on its own small satellite constellation, PhantomCloud (more on this later).

As for Vector, there was little to report during those four years. The only update said the company was buying engines from the rocket engine startup Ursa Major, the same company Phantom was using.

It is now the end of 2025, and the fate of these two companies has once again intertwined, in a most ironic manner. Last week I learned from Jim Cantrell that Vector had closed shop, and that its last remaining assets, some of which Cantrell himself had helped develop when he headed Vector, had been bought by Phantom. This includes several unused rocket stages, the vertical rocket test stands, a lot of computers, and hardware.

Colliding galaxies, as seen in the infrared and X-rays

Colliding galaxies in the infrared and X-rays
Click for original image.

Today’s cool image illustrates how beautiful images of heavenly objects don’t always have to be in wavelengths our eyes can see. With the wonders of modern technology, we can now see wondrous things in wavelengths that are invisible to us.

The picture to the right, cropped and reduced to post here, is a perfect illustration. It was released on December 1, 2025, and combines X-ray data from the Chandra X-ray Observatory with infrared data from the Webb Space Telescope. From the caption:

This view of NGC 2207 and IC 2163 takes a James Webb mid-infrared image (white, gray, and red) and adds the X-ray view from Chandra (blue). Together, it is quite an eye-catching result.

…Here, both spirals are shown face on, with the smaller of the two galaxies, IC 2163, at the upper left of the larger galaxy, NGC 2207, which dominates the center and lower right of the image. Both galaxies have long, spiraling, silver blue arms, dotted with specs of blue and red. Toward our upper left, the curving arms overlap, and bend toward their neighbors’ core.

In optical wavelengths the gossamer lines of structure would be lost, overwhelmed by the light of each galaxy’s stars.

European Space Agency hacked

8:43 am

It appears some of the European Space Agency’s (ESA) servers have been hacked, with some of its internal data placed for sale on the web.

On 26 December, reports began to emerge on X claiming that ESA had suffered a significant data breach, with a hacker using the alias “888” offering more than 200 gigabytes of data for sale. According to the hacker’s listing, the allegedly compromised data included source code for proprietary software, sensitive project documentation, API tokens, and hardcoded credentials.

ESA has since issued a statement claiming the data breach was limited, but according to information posted on X, the breach included “Confidential internal documents (Airbus Defence & Space, Thales Alenia Space)” and “sensitive technical information related to space programs.”

I wouldn’t be surprised if China is bidding for this information right now. Then again, Europe’s space effort is so unimpressive compared to China that China might not see the information worth much.

Russia’s early warning satellite constellation is apparently no longer functioning

8:32 am

The satellites in Russia’s constellation for giving its military early warning of missile attacks, dubbed EKS, have been one-by-one failing in recent years, and it now appears the last one has now experienced a malfunction as well.

After the launch of the 6th Tundra satellite in 2022, the Russian military seemingly gave up on the effort to deploy the EKS early warning constellation or, possibly, the industry was simply unable to build new satellites due to technical problems associated with the Western sanctions and/or financial problems. No fresh satellites were launched into the network in the following three years, while, according to an analyst of the Russian strategic nuclear forces Pavel Podvig, the orbital tracking indicated that from March 2025 to December of the same year, the number of operational Tundra satellites fell from three to just one, possibly as a result of in-orbit failures.

…As of December 2025, Kosmos-2552 (EKS-5) was the only satellite within the EKS system which did not show a clear sign of failure, according to Podvig, but the spacecraft did miss a maneuver expected in November 2025, based on the usual pattern of its detectable orbit adjustments.

None of this is a surprise. Russia’s invasion of the Ukraine has not only isolated the country, it has crippled it in numerous ways, both financially and technologically. It no longer has access to many western high tech components it had relied on, and the loss of all its international launch customers has left its rocket industry devoid of hard currency.

Thus, when Russia makes any grandiose claims about its future space plans, it is wise to harbor great doubts.

China launches Earth mapping satellite

8:20 am

China yesterday successfully placed what it called a “geographic mapping” satellite, its Long March 4B rocket lifting off from its Jiuquan spaceport in northwest China.

Its state-run press provided no additional information about the satellite, nor did it provide any information about where the rocket’s lower stages, using very toxic hypergolic fuels, crashed inside China.

The leaders in the 2025 launch race:

168 SpaceX
89 China (a new record)
18 Rocket Lab
17 Russia

SpaceX still leads the rest of the world in successful launches, 168 to 149.

The headwaters of an ancient Martian channel

11:46 am

glacial debris in canyon floor
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on October 24, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this simply as “irregular terrain.” It is far more than that. We are looking at a three-mile-wide shallow canyon, with what appear to be eroding glacial features on the canyon floor.

The location is at 35 degrees north latitude, so finding glacial features here is entirely unsurprising, especially because this location is the southern edge of the 2,000-mile-long mid-latitude strip in Mar’ northern hemisphere I label glacier country, because almost every picture shows such glacial features.

In this case, the channel also suggests a much more complex geological history, that could involve flowing water though flowing glaciers are increasingly becoming an alternative explanation.

SpaceX pulls Starlink service from Papua New Guinea

9:23 am

SpaceX has now withdrawn the Starlink services it informally had provided customers in Papua New Guinea after a volcano eruption in 2021 due to regulatory demands by the government there.

It’s been two and a half years since a volcano eruption tore apart Tonga’s underwater internet cables, and a sympathetic Kiwi MP pleaded to Elon Musk for help on their behalf. Musk, CEO of SpaceX, would answer Shane Reti’s call, offering his Starlink technology in aid of their reconnection to the world.

Starlink’s Pacific debut came with limited trials in American-owned Guam and the Northern Marianas, followed by the Cooks in April 2021. But for the wider Pacific community, its deployment in Tonga captured hearts and minds. The service, provided by a special satellite network, has been hailed as “transformational” in numerous island nations, broadening internet coverage to remote areas, some for the first time.

That is, unless, you’re in Papua New Guinea. Starlink’s attempts to gain licensing in PNG have been tied up since December 2023, with the Ombudsman Commission challenging the government over Starlink’s reliability. The Commission blocked licensing efforts in February 2024, and have argued that existing regulations may not be adequate to manage potential risks to public interest and safety.

In-fighting within Papua New Guinea’s government continues to block Starlink license approval, so it appears SpaceX has decided the best way to get a positive decision is to walk away, hoping the ensuing pressure from its customers might force action from the government.
