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.

Historical proof that today’s public schools are nothing but indoctrination mills poisoning minds

4:57 pm

A typical classroom in 1909
Click for original.

You want to know why today’s kids know nothing about America’s past, and in fact in many cases actually believe falsely that America invented slavery and has always been an evil oppressive nation founded on that even more evil concept of capitalism, you need only compare pictures of two typical public school classrooms, one from 1909 and one from 2025.

The picture to the right was taken in 1909, showing an elementary classroom in the Washington, DC area. Note the picture of President Teddy Roosevelt on the wall, surrounded by American flags. Note the blackboard that covers two entire walls, its entire face filled with detailed information these children were expected to learn. Note how there is nothing else. Very clearly the focus is on learning the basics of reading, writing, and arithmetic, with a lot of American history and science thrown in as well. As noted in the article of many such vintage classroom images from which this picture was drawn:

Students wear their best clothes for this formal photograph. The classroom features standard educational decor of the period—portraits of historical figures, maps, and instructional charts. Such photographs documented not just the students but the educational standards and resources of local communities.

As a child who grew up in the 1950s and 1960s, I can say that the classrooms of my day were quite similar. There was almost always a portrait of George Washington and the Declaration of Independence on the wall, along with map of the world and the U.S. And above all, the focus was on learning basic facts and essential skills.

The next picture below was taken in 2025 by a parent of an 11-year-old boy while attending a parent orientation night. It is also typical of the classrooms one sees nowadays in the public schools, and the contrast is more than striking.

Sierra Space finally completes preflight tests of its Tenacity Dream Chaser mini-shuttle

2:56 pm

Tenacity undergoing recent tow tests

Click for original image.

Sierra Space today announced that has finally completed the preflight ground tests of its Tenacity Dream Chaser mini-shuttle required prior to launch.

As part of its comprehensive testing campaign, Dream Chaser underwent Electromagnetic Interference and Electromagnetic Compatibility (EMI/EMC) testing at NASA’s Space Systems Processing Facility (SSPF). These tests verified the spacecraft’s ability to operate within expected electromagnetic environments throughout various missions.

The spacecraft also completed rigorous tow testing at KSC and Space Florida’s Launch and Landing Facility. For this phase, a Freightliner Cascadia truck, provided by Daimler Truck North America, towed the spaceplane at high speeds to simulate critical dynamics and validating autonomous navigational parameters during runway landing operations.

Additionally, Dream Chaser successfully demonstrated the ability to receive telemetry and distribute commands between the spacecraft and Mission Control in Louisville, Colorado over NASA’s Tracking and Data Relay Satellite System network. This key milestone tested the spacecraft’s readiness for real-time command and control during flight operations.

The testing campaign concluded with a post landing recovery rehearsal, which demonstrated the safing of vehicle systems and timely access to sensitive payloads. [emphasis mine]

The electromagnetic and telemetry began more than two years ago — along with standard vibration test — and under normal conditions should have been completed in only a few months. In fact, when that testing began the company expected to launch Tenacity to ISS on a Vulcan rocket sometime in 2024. While the vibration tests completed as expected, the other tests did not. Instead, we waited, and waited, and waited, with no word on the results, suggesting strongly that something had been found that made that launch impossible without significant changes.

The description of the tow tests that I highlighted above add further weight to this speculation. Such tow tests should have been done long before those final electromagnetic, telemetry, and vibration tests. To have to do such tow tests now suggests strongly that those ground tests found something wrong that required changes and further tow tests.

Though NASA has canceled its ISS cargo contract with Sierra using Tenacity, the company says it still plans to launch the mini-shuttle on an orbital demonstration mission late in 2026, with it landing back on a runway at Vandenberg Space Force Base in California.

Don’t put much money on this. This mini-shuttle was first proposed in 2014, and has been repeatedly delayed over and over again. It remains unclear whether it will ever launch.

  • Op-ed touting the benefits of a spaceport in Yuma, Arizona
    This proposal has been bouncing around Arizona now for about six years, with little progress. Its biggest problem is that almost all launches would have to fly over Mexico, and based on conflicting reports it is unclear Mexico is willing to agree.

New Glenn successfully launches Escapade orbiters AND lands 1st stage

2:29 pm

New Glenn first stage after landing
New Glenn first stage after landing

Blue Origin today successfully placed two the NASA Escapade Mars orbiters into space, its New Glenn rocket launching for the second time from Cape Canaveral in Florida.

More significantly, the company successfully landed the rocket’s first stage on a barge in the Atlantic. New Glenn is now the second rocket company capable of vertically landing and recovering an orbital first stage, after SpaceX.

Several take-aways: First, this first stage recovery took place almost exactly a decade after Blue Origin successfully landed vertically its suborbital New Shepard rocket, and almost a decade after SpaceX successfully did it with its Falcon 9 orbital rocket. It is a shame that it took Blue Origin so long to get to this point. It is also magnificent that it has finally made it happen. The United States now has two reusable rockets, with two more (by Rocket Lab and Stoke Space) expected to launch by next year.

Blue Origin is not likely to reuse this particular first stage, but its recovery will make future reuses likely and soon.

Second, Blue Origin made one interesting broadcast choice that I like. It listed the rocket’s altitude and speed in feet/miles and miles per hour, not kilometers. The engineers might have been using metric, but the audience is American, so using the traditional Imperial numbers is smart. Good for Blue Origin.

Third, Blue Origin’s announcers were once again annoying, distracting, ignorant, and childishly emotional. And they simply would not shut up, preventing the audience from hearing critical reports from mission control. They also seemed oblivious to reality, bragging repeatedly about the ten year gap between the first New Shepard landing and this landing, as if this was somehow a good thing. It was embarrassing to listen to.

The company would do a far better job selling itself by hiring announcers who are more serious and professional. Sadly, I have noted this problem from Blue Origin’s announcers now for almost a decade, with little change.

Finally, this success is a very big deal, both for Blue Origin and the United States. The company is now primed to begin regular launches next year, including the 27 launches Amazon has purchased for its Kuiper constellation.

For the U.S., this finally gives us a solid competitor to SpaceX. And that competition is finally going to force launch prices to drop significantly. SpaceX dropped prices, but not as far as it could because there was no pressure to do so from anyone else. Now there is that pressure.

As this was only the second launch by Blue Origin 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 116. Note that ULA hopes to launch its Atlas-5 rocket tonight.

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

3:09 pm

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.

The leftist protest at Berkeley this week: Feel the hate!

12:45 pm

All this guy wanted to do was selling
All this guy wanted to do was sell
“Freedom” t-shirts. Click for video.

While a lot of reports have done good work documenting the Antifa and leftist protests that attempted to shut down a Turning Point USA event on the campus of UCLA at Berkeley earlier this week (here, here, and here), I want to highlight one fundamental and truly ugly aspect of these protests that I think we no longer see because it has become so common.

While it is clear these leftist protesters have nothing positive to propose, it is their hate and anger that stands out above all. All they can do is vent hate, pure and simple.

The screen capture to the right is a typical result of this hate. It comes from video whereby this guy had set up a table outside the event, attempting to sell a variation of the “Freedom” t-shirt that Charlie Kirk was wearing when he was assassinated. A crowd of leftist mask-wearing protesters soon surrounded him, shouting obscenities and threatening him. Finally, one protester named Jihad Dphrepaulezz grabbed the t-shirts as well as a chain necklace from the man and ran. The man chased him and they got into a fight, resulting in this man’s bloodied face.

Dphrepaulezz has now been charged with assault and robbery. The t-shirt seller, who remains unidentified, was initially arrested but then released when the police determined he was the victim.

This violence however is typical now of the left at these protests, so typical we are no longer even shocked by it. It stems from blind angry emotions, driven further by an utter ignorance that embarrasses them if challenged in any way. If you were to ask them to give any examples proving that Charlie Kirk and Turning Point USA supported bigotry or “fascism”, their response would be incoherent or confused, because they clearly have never listened to even one nanosecond of any Turning Point USA event, with or without Charlie Kirk. I have, and I can say unequivocally that Kirk or his organization were and are the exact opposite of these false slanders. Kirk and his organization have always stood for individual rights, freedom, and open debate. They also stand for an end to bigotry, for not ranking people by their skin color or religion but solely based on their character and actions.

And above all, Kirk and his organization have always stood for bringing the two sides of the political debate together to talk as civilized rational human beings about the issues everyone so passionately cares about.

The left however can no longer debate anyone rationally. Instead, we have these protests, designed to silence debate. And to do so they scream obscenities and insults, chanting “Fascists out of Berkeley!” repeatedly as if that means anything. And if that doesn’t work, they next turn to violence, as happened above to this t-shirt vendor.

This tactic — of screaming and disrupting events to silence them — isn’t news, as this kind of violent protest behavior has been standard leftist tactic to silence speech now for more a decade. At Berkeley in 2017 it prevented then-Breibart editor Milo Yiannopoulos from speaking there. Since then it has been used in numerous campuses nationwide to shut down conservative events.

What is different now is the level of emotional hate exuded by these protesters. They are literally so filled with this venom that they now almost routinely lose control of themselves, resulting in violence and vandalism of the sort seen above, that even a decade ago was rare.

Below are two more clips. All I see is hate. Hate for the right. Hate for debate. Hate pure and simple.

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 edge of Mars’ north polar ice cap

The fringe of Mars' perennial ice cap
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on September 29, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

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.

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.

Avio to provide solid-fueled motors to Lockheed Martin and Raytheon

9:08 am

The Italian rocket company Avio has now signed deals with both Lockheed Martin and Raytheon to provide each with solid-fueled rocket motors for U.S. missiles, built at its planned American-based factory, expected to begin operations in 2028.

Under the arrangement with Lockheed Martin, “Lockheed Martin will have preferred access to a portion of the Avio USA plant production capacity to meet future demand for its products,” according to Avio. Tim Cahill, president of Lockheed Martin Missiles and Fire Control, said the collaboration “positions us to increase production of essential capabilities and deliver them to our customers faster as global demand grows.”

Raytheon will receive similar preferred access to production capacity under a comparable agreement. The deal follows a July 2024 contract between the companies for preliminary engineering work on a tactical rocket motor for Raytheon’s Standard missile program for the U.S. Navy. Bob Butz, vice president of operations, supply chain and quality at Raytheon, said the agreement “will help establish an additional supplier of solid rocket motors within the U.S.”

In both cases, these solid-fueled motors will be used in U.S. missiles.

Since Avio regained control of its rockets and engines from Arianespace — the government-controlled commercial arm of the European Space Agency (ESA) – it has been moving very fast to obtain customers worldwide. Under ESA control, Arianespace was focused on doing business in Europe, so establishing a factory in the U.S. to garner U.S. business was never even considered. Avio is not hindered by such restrictions, and it is therefore looking for profits wherever it can find them. It has committed almost a half billion dollars to build this U.S. factory, and has begun signing up international satellite companies for its Vega-C rocket. It is also begun work on a Grasshopper-type test vehicle, with plans to incorporate this concept into Vega-C, making its first stage reusable.

The above deal also indicates that Avio is grabbing market share from the established American makers of solid fueled rockets, especially Northrop Grumman. Apparently those American companies aren’t providing manufacturing capacity required by the Pentagon.
