Two more SpaceX launches

1:15 pm

SpaceX yesterday completed two launches, placing a total of 58 Starlink satellites into orbit.

First, a Falcon 9 lifted off from the Kennedy Space Center in Florida, carrying 29 Starlink satellites. The first stage completed its 8th flight, landing on a drone ship in the Atlantic.

Four hours later, a second Falcon 9 lifted off from Cape Canaveral, carrying another 29 Starlink satellites. Its first stage completed its 24th flight, also landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

149 SpaceX
70 China
14 Rocket Lab
13 Russia

SpaceX now leads the rest of the world in successful launches, 149 to 117.

November 11, 2025 Zimmerman/Space Show appearance

3:55 pm

David Livingston has now uploaded the audio of my appearance on the Space Show earlier this week on November 11, 2025.

You can download the audio of the program here.

To watch the zoom broadcast, go here.

The most important point I made during this show was at the beginning, as described by David Livingston’s summary of the show:

During the program Bob made some predictions about the future of space exploration. Zimmerman claimed that SpaceX, rather than NASA, is currently the most effective American space program. He predicted that in two years, everyone would recognize SpaceX’s dominance. Zimmerman also suggested that NASA’s role should become less significant, with its focus shifting to supporting private space endeavors rather than leading space exploration efforts.

I was actually more blunt. I said that SpaceX is the American space program right now, and that SpaceX doesn’t need NASA or the U.S. government in any way to carry it out, as it is entirely funded from Starlink revenues. I also predicted that NASA and its Artemis program is now irrelevant, though no one yet realizes it.

I added that this is going to be one of my many predictions that everyone will claim they made, two years hence. I’m making it now. I am quite willing to bet I will be right.

Everyone should take a listen. You will find the discussion afterward most revealing.

The orbital propulsion module for India’s Chandrayaan-3 lunar lander drifts back into lunar orbit

3:48 pm

When India’s Chandrayaan-3 spacecraft arrived in lunar orbit in August 2023, it separated into three units, the lander, a lunar orbiter, and a propulsion unit used to get everything to the Moon.

While the Vikram lander successfully touched down several hundred miles from the Moon’s south pole and the Chandrayaan-3 orbiter continues to make observations of the Moon, in October 2023 engineers had the propulsion module do a burn that sent it out of lunar orbit and into an Earth orbit that was close to one of the Lagrange points where the gravity of the Earth and Moon are balanced.

Now, three years later, that module has drifted back into lunar orbit, where it has since done two close fly-bys of the surface.

This intricate orbital dance culminated when the module once again entered the Moon’s SOI [sphere of influence] on November 4, 2025, an event marking the transition where lunar gravity dominates its motion.

The first recorded lunar flyby occurred on November 6, 2025, at a distance of 3,740 km from the lunar surface, though it was outside the Indian Deep Space Network’s (IDSN) visibility range. A second, closely monitored flyby took place on November 11, 2025, bringing the module within 4,537 km of the Moon and well within observation capabilities.

These events noticeably altered the satellite’s orbital parameters, expanding its orbit size from 100,000 x 300,000 km to a massive 409,000 x 727,000 km and shifting its inclination from 34° to 22°.

It is not clear what happens next. Having this module in lunar orbit could be an issue for present and later orbiters, as no orbit around the Moon can ever be stable. At some point India’s space agency ISRO needs to properly dispose of this unit, either by sending into the Moon or out of the Moon-Earth system entirely. I am of course assuming it has the fuel to do so.

Bezos releases new video of the New Glenn first stage landing yesterday

3:35 pm

Jeff Bezos, founder of Blue Origin, today released on X new footage showing from a distance the full landing sequence of New Glenn’s first stage on a barge in the Atlantic.

I have embedded it below. It is quite spectacular, and suggests the Blue Origin team can match SpaceX’s team in controlling a landing spacecraft. The stage comes down several hundred feet to the side of the barge, hovers, and then slides sideways to touch down exactly on target. As Bezos notes:

We nominally target a few hundred feet away from Jacklyn to avoid a severe impact if engines fail to start or start slowly. We’ll incrementally reduce that conservatism over time.

This is not unlike the landing maneuver performed by Starship prior to capture by the tower chopsticks. If Blue Origin can do it also, it means it has capabilities it has been hiding for the past decade due to its slow and timid testing/launching pace.

Comet C/2025 K1 — NOT interstellar 3I/Atlas — breaks up as it passes closest to the Sun

12:10 pm

The broken apart nucleus of Comet 3I/Atlas
Click for original image.

CORRECTION: I originally posted this story thinking the comet imaged was the interstellar Comet 3I/Atlas. It is not. It is a different one. I have changed to post below to correct my error.

——————
Sometime on November 11, 2025, the nucleus of interstellar C/2025 K1 broke into three pieces as it passed through its closest and hottest point to the Sun.

The image to the right, cropped and reduced to post here, comes from images of the break-up taken by the Virtual Telescope project, which gathers data from many small telescopes remotely.

From the first link, translated by Google from the Italian:

Its trajectory led it, in early October, to pass through a point of minimum distance from the Sun (perihelion) quite close to our star, about 0.33 astronomical units, just outside the orbit of Mercury. Because of this “short” distance from the Sun, it experienced high solar irradiation, which caused a significant increase in the temperature of the surface and internal layers of the nucleus.

These are precisely the conditions under which a “breakup” event is expected: depending on the internal properties of the nucleus—namely, its porosity, its state of cohesion, its composition, and the percentage of ice—it is possible that the increase in temperature could cause significant “outgassing,” a sudden and violent outflow of gaseous and dusty material, and the consequent fragmentation of the nucleus, sometimes into a few pieces of roughly similar size, sometimes into a cloud of fragments and debris that spread along the trajectory of the original comet.

…”From an initial quick analysis of the images, we can confirm that there are certainly two fairly similar pieces, whose brightness maxima are separated by approximately 2,000 km (distance projected on the star field); “Furthermore, we can intuit the presence of a third, smaller and fainter fragment to the left of the pair,” observes Mazzotta Epifani.

It will be interesting to see if the same thing happens to interstellar Comet 3I/Atlas as it makes its own pass close to the Sun.

China’s Shenzhou-20 crew on Tiangong-3 returns on Shenzhou-21 capsule

11:27 am

The Tiangong-3 station, as presently configured
The Tiangong-3 station, as presently configured

After about a week of analysis, China today announced that the Shenzhou-20 capsule was too badly damaged to bring its crew back from its Tiangong-3 space station.

In making that announcement China finally revealed some details about the damage.

Tiny cracks have been found in the return capsule’s viewport window, which are most probably caused by external impact from space debris, according to the [China Manned Space Agency (CMSA).]

To get that crew home, which had already spent almost seven months in orbit, China had them board the Shenzhou-21 capsule that had only launched two weeks earlier on October 31, 2025 and use it to return to Earth today.

This leaves the present three astronauts on Tiangong-3 without any way to get back to Earth should something go wrong with the station.

China apparently had limited options. It doesn’t have enough docking ports on Tiangong-3 to dock three Shenzhou capsules to it, so one capsule had to undock and leave the station to make room for a replacement capsule.

Undocking Shenzhou-21 however is puzzling. Why didn’t China instead undock the damaged Shenzhou-20 capsule and de-orbit it? Had it done so, the six astronauts would have had only one lifeboat for three, but the docking port would have been opened for a new rescue capsule. There have been indications that China is preparing the next Shenzhou-22 capsule and a Long March 2F rocket for launch, though China has not provided any information about when that launch will occur.

With Shenzhou-21 gone, the three remaining Tiangong-3 astronauts are truly stranded in space, with no way home.

Amazon renames its proposed internet constellation from Kuiper to Amazon LEO

9:59 am

Amazon today announced that it has renamed its proposed internet constellation from the initial internal code name “Kuiper” to “Amazon LEO, to give “a simple nod” to its location in low Earth orbit.

Our long-term mission remains the same, and we’re making good progress against it. We now operate one of the largest satellite production lines on the planet. We’ve invented some of the most advanced customer terminals ever built, including the first commercial phased array antenna to support gigabit speeds. And we now have more than 150 satellites in orbit [154 to be exact], and customers and partners like JetBlue, L3Harris, DIRECTV Latin America, Sky Brasil, and NBN Co., Australia’s National Broadband Network operator, already signing up to deploy the service.

The company’s FCC license requires it to have 1,600 satellites in orbit by July 2026. To even get close to this number the three launch companies that have Amazon launch contracts, ULA (46 launches total), Arianespace (18 launches), and Blue Origin (27 launches) have got to start launching regularly. ULA has completed three launches, and promises to do many in 2026. Arianespace says it will begin launches in 2026. Blue Origin has said nothing, but the successfully launch yesterday of New Glenn suggests it will also begin Amazon launches in 2026.

ULA’s Atlas-5 rocket launches Viasat communications satellite

8:40 pm

ULA tonight successfully launched a Viasat communications satellite, its Atlas-5 rocket lifting off from Cape Canaveral in Florida.

This was the fifth launch for ULA in 2025, matching its count from last year. For the past year the company has repeatedly promised a launch rate of once to twice a month, but as yet to do so. In fact, it hasn’t managed twelve launches in a year since 2016. Hopefully this will change in the coming year.

With this launch, ULA only has eleven Atlas-5s left in stock before the rocket is retired, with five of those launches for Amazon’s Kuiper constellation and six for Boeing’s Starliner manned capsule. While the Kuiper launches will almost certainly happen by the end of 2026, the Boeing Starliner missions are very much in limbo, as that capsule itself remains in limbo with it entirely unclear when it will carry astronauts again for NASA.

As this was only the fifth launch by ULA in 2025, the leader board for the 2025 launch race remains unchanged:

147 SpaceX
70 China
14 Rocket Lab
13 Russia

SpaceX still leads the rest of the world in successful launches, 147 to 117.

France’s president puts forth a new national space policy

10:43 am

Capitalism in space: In a speech yesterday France’s president Emmanuel Macron proposed a new national space policy with increased spending for defense and an increased focus on encouraging France’s private space sector. According to his speech, the strategy has five main goals:

  • Maintaining autonomous access to space – ensuring France and Europe retain the independent capability to launch and operate missions without external reliance.
  • Reassessing the industrial and commercial model – promoting competitiveness, public–private cooperation, and the growth of dual-use technologies. [emphasis mine]
  • Expanding strategic and defence capabilities – reinforcing surveillance, secure communications, and the protection of orbital assets against emerging threats.
  • Adopting a more assertive approach to science and exploration – increasing participation in international research missions and developing new exploration technologies.
  • Revitalising European space cooperation – through enhanced competitiveness, a “European preference” in procurement, and new models of governance.

The highlighted point is the most important. Macron clearly wants France’s aerospace industry to lead Europe in space, and to do so he is now officially abandoning his country’s long reliance on doing everything cooperatively through the European Space Agency (ESA) and its commercial arm, Arianespace.

This change has been on-going for the past two years, but Macron has now made it official. France will now do what NASA has been doing for the past fifteen years, shift from the government-run model to the capitalism model, where instead of having ESA and Arianespace build and own everything for France, France will buy what it needs from private European companies, with a emphasis on giving those contracts to French companies.

To do this Macron proposed a 30% increase in spending on civilian space projects through 2030, and a 70% increase in France’s defense budget for that same time period.

France has always had the strongest aerospace industry in Europe, but it has been shackled badly by Europe’s desire to do everything in partnership through a government-run agency, just as America’s space industry was shackled by NASA prior to 2010. If Macron follows through with this policy change, expect some great things from France in space in the coming decade.

Is China preparing to return its stranded astronauts in its damaged Shenzhou capsule?

10:00 am

According to reports from China, it appears they are preparing to return the three-person Shenzhou-20 crew on their damaged Shenzhou-20 capsule on November 14, 2025, rather than launch a replacement capsule as had been rumored previously.

China has issued a temporary airspace restriction over Inner Mongolia for 3:20 to 3:50 a.m. Eastern (0820-0850 UTC, or 4:20-4:50 p.m. Beijing time) Nov. 14, according to a Notice to Airmen (NOTAM) published by the Hohhot Flight Information Region under the Civil Aviation Administration of China (CAAC).

The airspace closure notice matches an area covering the Dongfeng landing site, an area in Inner Mongolia roughly 60 to 90 kilometers to the east-southeast of the Jiuquan Satellite Launch Center, which has been used for all Shenzhou crewed spacecraft returns since 2021.

None of this is confirmed as yet, as China’s state-run press continues to be very secretive about this entire affair. It as yet not released any details about the damage to Shenzhou-20, nor has it been forthcoming with any details about the next steps it plans to take.

The earliest observations ever of a supernova exploding suggest the blast was bi-polar

9:29 am

Figure 4 from the paper
Click for full graphic. CSM stands for the
circumstellar matter that surrounded the star
prior to eruption.

Using the Very Large Telescope in Chile, astronomers were able to observe a supernova in its very earliest moments after eruption, the earliest yet, and determined the eruption did not flow outward in all directions, but appeared to be bi-polar, as indicated by the cartoon to the right.

To capture the snapshot of the April 2024 supernova, astronomers used the European Southern Observatory’s Very Large Telescope in Chile, which was able to look at the polarization, or orientation, of the supernova’s light. Using a technique called spectropolarimetry, the researchers used the light’s polarization to re-create the explosion’s shape in its first moments. Their results showed that the light emanated not uniformly, like the light from a typical star, but elongated, shaped like an olive.

You can read their paper here. The cartoon comes from Figure 4, and is their “most plausible” interpretation of the data.

This bi-polar shape suggests that in the initial stages of the eruption the material shot out the star’s poles, as seen routinely in planetary nebulae as well as other eruptive stars like Eta Carina. The data also suggests the initial explosion was shaped by the circumstellar material surrounding the star. Such material tends to concentrate at a star’s ecliptic, like our solar system, With less material at the poles, the initial blast favored those directions.

Theorists will now use this data point to better refine the models that attempt to explain how supernovae explode.

German rocket startup Isar Aerospace is getting ready for 2nd launch attempt in Norway

9:15 am

Isar's first launch attempt fails
Spectrum falling seconds after its launch
in March 2025

The German rocket startup Isar Aerospace has now delivered the stages of its Spectrum rocket to Norway’s Andoya spaceport, in preparation for its second launch attempt following the first launch failure in March.

On 13 November, an Isar Aerospace update on its social channels revealed that, just over seven months after its first flight ended in a fireball, the company had returned to its launch facilities at the Andøya Spaceport in Norway in preparation for the rocket’s second flight. While brief, the update stated that the main and upper stages for the flight had arrived at the company’s launch pad and that it was “gearing up for pre-flight testing.” The update did not include an expected launch date.

The company in September had completed its investigation into the March failure, determining the failure was an inability of the rocket to maintain its proper attitude control.

Road closure announcements in Norway suggest that this launch will occur prior to December 21, 2025, but this is decidedly unconfirmed. If the launch takes place then and is successful, Norway’s Andoya spaceport will have become the first European-based spaceport to launch an orbital rocket, beating out the two spaceports in the United Kingdom and the Esrange spaceport in Sweden.

Space energy startup Star Catcher successfully tests power beaming using lasers

9:02 am

StarCatcher laser transmitting to solar panel
StarCatcher laser transmitting power during Florida tests.

Space energy startup Star Catcher last week successfully completed a demonstration in Florida of its power beaming technology, transmitting energy using lasers to off-the-shelf solar panels used by satellites and spacecraft.

Using an advanced suite of multi-wavelength lasers, the team delivered more than 1.1 kW of electrical power to commercial off-the-shelf solar panels at Space Florida’s Launch and Landing Facility. … During the demonstration, Star Catcher delivered one to ten Suns of optical energy to multiple commercial off-the-shelf single- and triple-junction solar panels commonly used in space, confirming compatibility with standard spacecraft hardware, and validating the company’s approach to “supercharge” satellites with significantly more power via highly concentrated beams of light. Among them was an Astro Digital triple-junction solar panel — the same hardware used on the company’s flight-proven satellite buses — demonstrating readiness to power customer missions in orbit.

Star Catcher also delivered power to several customer payloads representing key market segments such as space data centers, in-space manufacturing, and remote sensing. The systems operated on beamed power as customers conducted live experiments, demonstrating both hardware compatibility and strong interest in this emerging power infrastructure.

Among the demonstrations, Star Catcher wirelessly transmitted energy to Intuitive Machines’ Lunar Terrain Vehicle (LTV) and recharged its onboard batteries.

The company plans to fly an orbital power-beaming demonstration satellite next year. If successful, it will try to raise the investment capital to launch power-beaming satellites in both Earth and lunar orbits by 2030, where they can more efficiently provide power. It already has signed six preliminary agreements with a variety of space-based companies such as Intuitive Machines. In the case of rovers like Intuitive Machines LTV, this technology will be an excellent way to charge batteries in the permanently shadowed craters on the Moon, where direct sunlight will not be available.

Uzbekistan signs deal to possibly fly astronauts on Vast’s Haven-1 space station

8:28 am

Haven-1 with docked Dragon capsule
Haven-1 with docked Dragon capsule

According to a press release earlier this week from the Uzbekistan government, it has signed an agreement with the American space station startup Vast to possibly fly its astronauts on Vast’s Haven-1 space station, scheduled for launch early next year for a three year mission that will include four two-week manned occupancies.

The parties discussed prospects for long-term cooperation with Vast, including participation in joint scientific research, personnel exchange programs, and the involvement of Uzbek specialists in upcoming missions following the successful launch of the Haven-1 orbital station.

Discussions also covered the potential involvement of Uzbek scientists and engineers in research on artificial gravity, life support systems, and orbital architecture within the framework of the Haven-2 project, the proposed successor to the International Space Station.

Neither Vast nor Uzbekistan apparently made any firm commitments to fly astronauts to Haven-1, but the agreement clearly laid the groundwork for doing so, if not on Haven-1 then on Vast’s follow-up much larger station, Haven-2. At the moment Vast has not yet announced any of passengers or crew for the four Haven-1 manned missions, so there clearly is room for an astronaut from Uzbekistan, assuming it is able and willing to pay the freight.

Firefly identifies cause of first stage explosion during static fire test in September

8:01 am

Alpha on the launchpad
The Alpha first stage, prior to September explosion

Firefly yesterday announced it has completed its investigation into the explosion during a static fire test in September that destroyed the first stage of the Alpha rocket during final preparations prior to launch.

Following a thorough review of the Alpha Flight 7 first stage ground test on September 29, Firefly identified a process error during stage one integration that resulted in a minute hydrocarbon contamination, which then led to a combustion event in one of the engines during the ground test. The test stand structure remained intact and no other facilities were impacted.

…Firefly immediately took action and implemented corrective actions, which included increasing inspection requirements for the fluid systems, optimizing the first stage sensors, and incorporating additional automated aborts. Firefly also implemented key process improvements following a daylong quality stand down where the production, integration, and test teams conducted exercises to review and optimize existing procedures. As part of Firefly’s effort to improve reliability and quality, the team will continue to hold regular exercises for sustained process enhancements.

The company also said the problem was not a design issue with the rocket.

It appears from the company’s press release that the contamination occurred because of a work force quality control issue, that required a major daylong review by all their employees to make sure their operations in building the stage would be more rigorous going forward.

The plan now is to pull another first stage from the company’s production line and stack that with the original upper stage. The target date for launch is late this year or early next year, “depending on range availability.”

Firefly had hoped to do five launches in 2025. At this moment it has only attempted one, in April, which failed. That investigation took until mid-September to complete. The next launch attempt was then delayed by the first stage explosion.

I imagine the company very much wants to get at least one launch off this year. I also imagine it is aggressively reviewing its rocket work force due to these issues.

Saturn’s rings, warped by one of Saturn’s moons

Daphne inside Saturn's rings
Click for original image.

Cool image time! Rather than post another Mars image, I decided today to dig into the archive left from the Cassini orbiter that circled Saturn from July 1, 2004 until September 15, 2017. The picture to the right, cropped to post here, was taken on September 13, 2017, only two days before the orbiter burned up in Saturn’s atmosphere. From the caption:

This image of Saturn’s outer A ring features the small moon Daphnis and the waves it raises in the edges of the Keeler Gap. The image was taken by NASA’s Cassini spacecraft on Sept. 13, 2017. It is among the last images Cassini sent back to Earth. The view was taken in visible light using the Cassini spacecraft wide-angle camera at a distance of 486,000 miles from Saturn. Image scale is 2.7 miles [per pixel].

The moon is traveling downward in this image. As it moves past the outer ring, its gravity causes that edge to ripple, producing the waves.

The scale will give you an idea of how big the rings of Saturn are. The Keeler Gap is at the outer edge of the A ring of Saturn, which is the outermost ring that is clearly visible using ordinary amateur telescopes. That edge however is more than 90,000 miles from Saturn. And grayish bands to the right of Daphne and the Keeler Gap are only the outer half of the A ring, which is by itself about 9,000 miles wide.

First Soyuz-5 rocket arrives at Baikonur

9:50 am

According to Russia’s state-run press, the first Soyuz-5 rocket has arrived at the Baikonur spaceport in Kazakhstan, with a targeted maiden launch scheduled for December.

Soyuz-5 is designed to replace Russia’s soon-to-be retired Proton rocket, as well as the Ukrainian Zenit rocket that is no longer available because Russia invaded the Ukraine. It was first proposed in 2016, with its development proceeding in fits and starts since then. Part of the problems has been Kazakhstan, which demanded (and apparently received) a larger cut from Russia before it would allow Soyuz-5 to launch at the planned launchpad at Baikonur.

A larger factor in the delays has been a shortage of cash in Russia itself, as well the generally slow culture of its aging aerospace industry. However, in the case of Soyuz-5, it appears Russia managed to speed things up, as previous reports in 2024 suggested this first launch would be delayed until 2026.

SpaceX signs Starlink deal with major African telecommunication company

9:28 am

In a major deal that will make Starlink available across a wide swath of Africa, SpaceX has now signed an agreement with the African telecommunication company Vodacom, which operates in 47 African countries.

Vodacom will market for SpaceX its Starlink terminals, aimed specifically in rural areas where traditional land lines are not available.

The African company [Vodacom, majority owned by Britain’s Vodafone, has been seeking to ‍close connectivity gaps across the continent through low-earth orbit satellite technology which can help provide internet even in tough terrains. Vodacom will ​integrate Starlink’s satellite technology for data relay into its ‌mobile network and will be authorized to resell equipment and services from the SpaceX-owned firm to customers in Africa, the company said in a statement.

The parent company Vodafone has also signed deals with the satellite constellations being launched by AST SpaceMobile and Amazon, so it is aggressively seeking numerous avenues for getting service to customers in those rural areas.

It appears that Vodafone will have to obtain government permission from each country, but except for South Africa the company does not see this as a serious problem. South Africa however is presently run by communist bigots who are demanding SpaceX impose racial hiring quotas on its operations before approving Starlink, and SpaceX quite rightly is telling it to go pound sand.

India tests Gaganyaan parachutes again

9:15 am

Artist rendering of India's Gaganyaan capsule
Artist rendering of India’s Gaganyaan capsule

India’s space agency ISRO on November 3, 2025 successfully completed another drop test of the parachutes it will use on its Gaganyaan manned orbital capsule, this time testing the chutes in extreme conditions.

Explaining the November 3 test, the Isro statement said the GCM parachute system comprises 10 parachutes of four types. “The descent sequence begins with two apex cover separation parachutes that remove the protective cover of the parachute compartment, followed by two drogue parachutes that stabilize and decelerate the module. Upon release of the drogues, three pilot parachutes are deployed to extract three main parachutes, which further slow down the Crew Module to ensure a safe touchdown,” said Isro. “The system is designed with redundancy—two of the three main parachutes are sufficient to achieve a safe landing.”

Using a pyro device, the main parachutes open partially, a process known as reefing, and then open fully after a predetermined period of time, referred to as disreefing. This step-by-step process is known as reefed inflation. An important aspect of the test was the successful validation of the main parachutes under possible extreme scenarios of delay in the disreefing between the two main parachutes.

The August drop tests were from a helicopter at about 3 kilometers. The November drop tests took place from an airplane at about 2.5 kilometers.

The agency has indicated the first unmanned orbital test flight of Gaganyaan has been delayed from this year to early next, possibly as early as January. It plans to do at least three unmanned flights in 2026 before putting humans on board in early 2027.

Canada’s Nova Scotia spaceport schedules a suborbital launch for November

9:05 am

Proposed Canadian spaceports
Proposed Canadian spaceports

The competition heats up: Maritime Launch Services, the startup that has been trying to establish Spaceport Nova Scotia since 2016, has now issued a “notice to airman” (NOTAM) outlining the range restrictions for a suborbital launch window from November 18 to November 24.

The launch is being conducted by the Netherlands rocket startup T-Minus, which signed a deal with Maritime in June 2025 to do two such launches of its Barracuda rocket before the end of this year.

The T-Minus Engineering Barracuda hypersonic test platform “is a single-stage, solid-fuel suborbital vehicle that stands approximately 4 metres tall. It features a booster with a diameter of 200 millimetres and a payload compartment measuring 1000 millimetres. Barracuda can carry payloads of up to 40 kilograms to altitudes reaching 120 kilometres.”

The only launch that has previously taken place at this spaceport was in 2023, when students from York University did a short 8-mile-high suborbital launch of a student-built rocket.

Maritime is now in a tight competition with another spaceport startup, Nordspace, which is pushing hard to initiate launches from its Newfoundland spaceport to the north. It remains unknown whether either can be made profitable.

Goldstone antenna damaged and out of service

8:49 am

The Goldstone antenna in California that is a major component in NASA’s Deep Space Network (DSN) that it uses to communicate with interplanetary spacecraft was damaged recently and is presently out of service, with no known date for when or even if it will be repaired.

NASA’s Jet Propulsion Laboratory confirmed Nov. 10 that the 70-meter antenna at the Deep Space Network (DSN) site in Goldstone, California, has been offline since Sept. 16, with no timetable for its return to service. “On Sept. 16, NASA’s large 70-meter radio frequency antenna at its Goldstone Deep Space Communications Complex near Barstow, California, over-rotated, causing stress on the cabling and piping in the center of the structure,” JPL said in a statement to SpaceNews. “Hoses from the antenna’s fire suppression system also were damaged, resulting in flooding that was quickly mitigated.” [emphasis mine]

This statement suggests that as workers were changing the antenna’s orientation, it was moved too far in one direction, beyond the normal limits of that piping and cabling. The immediate question that the JPL statement avoids is this: What caused the antenna to “over-rotate”? Did something fail to stop it from going too far? Or was this an example of simple human error, whereby the person rotating the antenna failed to pay attention and allowed the antenna to exceed its limits?

Either way, the loss of this antenna not only poses a serious limitation in getting data back from the various unmanned probes at Mars, Jupiter, and elsewhere, it is also a problem for the upcoming Artemis-2 mission in the spring of ’26, which will rely on the Deep Space Network to communicate with the astronauts on Orion as it goes to and from the Moon. The network’s other two antennas in Spain and Australia can pick up the slack, but the system will have less redundancy, and more important, other missions will likely have to delay communications in order to give Artemis priority.

The picture shows what the science team labels as a “fringe of perennial ice.” For this picture, north is down. The white stuff on the top half of the image is that perennial ice, while the dark material at the bottom is likely a mixture of dust and debris that is still impregnated with ice.

Mars is a very icy world. Orbital data now suggests that above 30 degrees latitude there is a lot of near surface ice, though it is often mixed in with the red planet’s ample dust, blown there for eons. This location however shows us a place where that ice is on the surface, and is generally pure.

That does not mean however this will be a good location to establish a colony.

On the Space Show tonight

10:57 am

I will be making another long appearance on the Space Show tonight with David Livingston, beginning at 7 pm (Pacific). If you want to listen and even participate, note that the toll free phone number is no longer available. Instead, you need to go through zoom, as follows:

Listening Instruction for today’s BOB ZIMMERMAN discussion Zoom program. We want to hear from you with your ideas, thoughts and information. Please use the Zoom numbers below but you need to email me at drspace@thespaceshow.com for the Meeting ID. Participation in the Zoom room is for large donors to The Space Show as a way of showing our thanks for helping to make The Space Show possible for 25 years. The Space Show is a listener supported program so if you like our programming, please support us.

There is a PayPal button on our home page in the upper right area. Zelle donations us david@onegiantleapfoundation.org. You can also subscribe to us using Substack.

In addition to the above, if you previously called using our toll free number, unlike that number, calling us on a Zoom phone number enables you to listen to the entire program and join the discussion. This is far better than the old toll free number in which you had to get off the line to make room for other callers.

Kazakhstan expanding its access to multiple internet satellite constellations

9:40 am

It appears the Kazakhstan government is making multiple internet satellite constellations available to its citizens in an effort to increase competition and lower costs.

Kazakhstan first engaged with Starlink in 2023, following government frustration over the slow pace of domestic telecom expansion. The project initially connected 2,000 rural schools, and by mid-2024 nearly 1,800 had access to satellite internet.

Authorities briefly considered banning satellite internet services operated from abroad late last year, citing national security concerns, but withdrew the proposal after a public backlash.

Meanwhile, competition in the country’s nascent satellite internet market is heating up. In September 2024, Kazakhstan signed an agreement with Amazon to bring its Project Kuiper satellite network to the country, setting up a future rival to Starlink. Prime Minister Olzhas Bektenov said the move would help improve affordability and service quality. Chinese firm Spacesail Kazakhstan, a subsidiary of Spacesail International, has also registered at the Astana International Financial Centre (AIFC) with $17mn in capital, positioning itself as another potential player in the mega-constellation internet sector.

When Kazakhstan opened Starlink to all its citizens in June 2025, I noted how this deal indicated the country’s move away from Russia. Its willingness now to add Kuiper and Spacesail deals accelerates that move, in numerous ways. It not only wants its citizens to have capabilities that Russia cannot control, it wants to encourage competition to lower costs for those citizens. What a concept!

Like the Ukraine, Kazakhstan is working hard to exceed Russia in technology, in order to make it much harder for its big and very power-hungry neighbor to dominate or even invade it.

China’s Zhuque-3 reusable rocket now ready for its first launch

9:26 am

According to a report in China’s state-run press today, the Zhuque-3 (ZQ-3] rocket, built by the pseudo-company Landspace, is now cleared for its first launch, though no launch date has yet been announced.

If everything goes according to schedule, the first ZQ 3 will take to the sky in the near future at the Jiuquan Satellite Launch Center in northwestern China’s Gobi Desert and will attempt to recover its first-stage booster, according to the Beijing-headquartered enterprise.

The rocket is now undergoing technical testing at the Jiuquan spaceport, which has a dedicated launch service tower for the ZQ 3 series.

Though the rocket is methane-fueled, its overall design is a copy of work already done by SpaceX, with a stainless steel first stage with nine engines designed to land vertically after launch and then reused. It is also appears in the lead among about a dozen Chinese pseudo-companies attempting to build reusable rockets.

The Chinese government has recently been pressuring its pseudo-companies to accelerate development. Right now, only three have done any static fire tests, and only one, Landspace, appears ready to launch. There have even been rumors that China might reorganize these fake companies into a government-run operation.
