The management at the Jet Propulsion Lab (JPL) in California today announced it will be laying off 550 people this week, about 11% of its work force.
As part of this effort, JPL is undergoing a realignment of its workforce, including a reduction in staff. This reduction — part of a reorganization that began in July and not related to the current government shutdown — will affect approximately 550 of our colleagues across technical, business, and support areas. Employees will be notified of their status on Tuesday, Oct. 14.
As the statement makes clear, this reduction is unrelated to the government shutdown, and is also mostly unrelated directly to the 24% budget cut the Trump administration wishes to impose on NASA. JPL has had major management issues in the last few years, including two previous rounds of layoffs of similar amounts. Much of these budget issues stem from the cancellation by NASA of the Mars sample return mission, which JPL was to play a major part. That money is gone, and even if the mission is resurrected, JPL is almost certainly not going to play a major part.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
A mid-day pause: I posted twice in the past, but think it should be seen again. As I wrote in 2021,
On this day when all should be celebrating Christopher Columbus and his willingness “sail beyond the sunset,” to use a phrase from Tennyson, this short video give us an accurate picture of the man, his times, and his achievements. It also puts the lie to the bigoted, hateful, leftist slanders that have been used in recent years to poison his legacy.
Aberystwyth University in Wales this week delivered the spectometer instrument, dubbed Enfys, to be installed on Franklin Mars rover being built by the European Space Agency (ESA) and now scheduled for launch in 2028.
Enfys will work in tandem with PanCam – a camera system led by UCL’s Mullard Space Science Laboratory – to pinpoint mineral targets. These insights will enable the rover to select optimal drilling sites on the Martian surface, with samples analysed by other onboard instruments. The instrument being shipped today will be installed on the rover’s ‘Earth twin’ known as the Ground Test Model located at the Aerospace Logistics Technology Engineering Company in Turin.
Since the Franklin rover was initially supposed to launch in 2020, it is puzzling this instrument is only being delivered now. It could be that the original spectrometer was supposed to be provided by ESA’s original partner in the project Russia, but became unavailable when that partnership broke up due to Russia’s invasion of the Ukraine.
Or it could be the instrument’s development was simply late and behind schedule, as so many ESA’s projects routinely are. For example, the mission’s launch was first delayed from ’20 to ’22 because the parachutes weren’t ready. Then it was delayed until ’28 because of the break-up with Russia. Even now it remains uncertain it will meet this new date.
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.
“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.

According to a press release last week, the Lowell Observatory in Arizona is now making major changes to it management and operations due to “declines in federal research funding.”
The new framework centers on two defining pursuits: Planetary Defense, safeguarding our world from cosmic hazards, and Exoplanetary Research, seeking to understand distant worlds and the potential for life beyond Earth.
Declines in federal research funding, coupled with uncertainty about future national priorities, have impacted research institutions across the country. At the same time, Lowell’s historic reliance on internal funding to sustain research is no longer a viable long-term model. To ensure stability and growth, the Observatory will focus its efforts on key scientific areas while building new endowments to support the scientists and technology that drive discovery.
Essentially, it can no longer depend on easy federal cash (thank you Donald Trump!), and thus needs to actually do real research work in fields that others consider important. It will also abandon its “traditional academic tenure system.” Scientists who use the facility will now have to earn that right, in a case-by-case basis. And such researchers will have to be funded by “private, endowed support.”
In other words, Lowell is returning to the model that had been used by American researchers for most of the nation’s history, until World War II, getting their funding from private sources rather than the federal teat.
We should expect therefore the work at Lowell to become more effective and focused, something it has not been for decades.
Callisto’s basic design
Government in-action: After a decade of work, the German space agency DLR this week finally delivered for testing a prototype leg of the Callisto grasshopper-type demo rocket, intended by the European Space Agency (ESA) to demonstrate vertical take-off and landing.
On 9 October, the Institute of Structures and Design announced that it had delivered a qualification model of the demonstrator’s landing leg to the Institute of Space Systems in Bremen. According to a 3 December 2024 update, the leg will now undergo a series of tests at the Institute’s Landing and Mobility Facility, including deployment, touchdown, and vibration testing.
Once the qualification test campaign is complete and the landing leg design has been validated, the Institute of Structures and Design will proceed with the construction of the four flight-ready legs.
Note again that Callisto, as shown to the right, was proposed as a joint ESA and JAXA project in 2015. Only now, a decade later, as DLR delivered one prototype leg. The first test hop has been repeatedly delayed, so that now it is now not expected to happen until 2027, and that rocket will not even be an operational version, it will simply be a small scale prototype.
Meanwhile, SpaceX has landed its Falcon 9 first stage hundreds of times, and reused them dozens of times. Other companies are flying or building their own reusable rockets, and hope to fly operational versions next year.
The contrast between this government project and the private sector is quite embarrassing. What makes it even more embarrassing is that it is par for the course, and yet so many people still look to the government as the god who can get things done. When will people learn?

The eleventh orbital test launch of Starship/Superheavy is scheduled for 6:15 (Central) today. It will be the last flight for version 2 of Starship, and will also include the second reuse of a Superheavy booster.
Starship will repeat its flight plan from the previous flight, testing the deployment of dummy Starlink satellites, the relighting of its Raptor engines once in orbit, and various new configurations of its thermal protection system. It will come down in the Indian Ocean, either controlled or not. Future flights will use version three, and quickly move towards orbital flights and a return to Boca Chica for a tower chopstick capture and later reuse.
Superheavy, which flew previously on the eighth test flight, will do more engine configuration tests on its return, and will attempt a soft vertical splashdown in the Gulf.

In what appears to be a significant slap at its own rockets (especially its delayed Epsilon-S rocket), Japan’s space agency JAXA this week signed a two-launch deal with the American rocket company Rocket Lab.
Launching from Rocket Lab Launch Complex 1 in New Zealand, the two Electron missions will deploy satellites for JAXA’s Innovative Satellite Technology Demonstration Program. The first launch, scheduled from December 2025, will deploy the agency’s RApid Innovative payload demonstration SatellitE-4 (RAISE-4) spacecraft, a single satellite that will demonstrate eight technologies developed by private companies, universities, and research institutions throughout Japan.
The second launch, scheduled for 2026, is a JAXA-manifested rideshare of eight separate spacecraft that includes educational small sats, an ocean monitoring satellite, a demonstration satellite for ultra-small multispectral cameras, and a deployable antenna that can be packed tightly using origami folding techniques and unfurled to 25 times its size.
Rocket Lab has previously won contracts from several private Japanese satellite companies (Q-Shu, Astroscale, ALE), but this I think is the first JAXA contract it has won. What makes it significant is that JAXA has always focused on using its own rockets, the large retired H2A and the new H3 as well as the smaller Epsilon-S. To go to an American company is somewhat unprecedented.
Though larger than Rocket Lab’s Electron rocket, Epsilon-S was being developed to compete for the same market. That development however has been plagued by failure, including explosions of engines during tests of both its upper and first stages in ’23 and ’24 respectively. After the second explosion JAXA announced in December 2024 the rocket’s first launch would not occur in the spring of 2025 as planned, but provided no additional information. Since then there have been no updates.
This Rocket Lab deal suggests the Epsilon program is in big trouble. In the long run however this might be a very good thing for both JAXA and Japan’s own nascent rocket industry. JAXA might finally be recognizing that building and owning its own rockets is not the best plan, that it would be better to use the capitalism model and simply be a customer buying the services from the private sector. At the moment Japan doesn’t yet have a viable commercial rocket sector, with only Mitsubishi having an operational commercial rocket, the H3 (mostly controlled by JAXA). There are a number of new startups however, including Interstellar, Honda, Space One, and Tispace, all of which have done tests of one kind or another. If JAXA is ready to abandon its own government rockets and buy the service from the private sector, those Japanese startups will start to prosper.
The Chinese pseudo-company Orienspace yesterday successfully placed three satellites into orbit, its solid-fueled Gravity-1 rocket lifting off from an ocean platform off the country’s northeast coast.
This was Orienspace’s second launch, both using its Gravity-1 rocket from the ocean. Of the three satellites, one was an Earth observation satellite, and the other two were part of the pseudo-company Geespace’s Geely constellation of satellites, though it is not clear if these are for its Internet-of-Things (IoT) constellation or for general communications. The IoT constellation already has 64 satellites in orbit out of a planned 240.
Another launch of China’s Long March 8A rocket was supposed to happen yesterday, but there is no indication in China’s state-run that it took place, nor any information about a rescheduled launch date. That state-run press also illustrated the pseudo nature of these Chinese companies by only mentioning Orienspace as an afterthought at the end of the article.
The leaders in the 2025 launch race:
129 SpaceX
59 China
13 Russia
12 Rocket Lab
SpaceX still leads the rest of the world in successful launches, 129 to 99. The company will try again this evening to launch its third mission for Amazon, placing a set of Kuiper satellites into orbit. Weather has scrubbed the past two attempts in the previous few days.

Using orbital data from Mars Reconnaissance Orbiter (MRO) of glaciers inside mid-latitude craters, scientists have concluded that there was a steady decline in the growth of those glaciers with each new glacial cycle.
They focused on craters with indicative signs of glaciation, such as ridges, moraines (piles of debris left behind by glaciers), and brain terrain (a pitted, maze-like surface formed by ice-rich landforms). By comparing the shapes and orientations of these features with climate models, they found that ice consistently clustered in the colder, shadowed southwestern walls of craters. This trend was consistent across various glacial periods, ranging from approximately 640 million to 98 million years ago.
The results show that Mars didn’t just freeze once—it went through a series of ice ages driven by shifts in its axial tilt, also known as obliquity. Unlike Earth, Mars’ tilt can swing dramatically over millions of years, redistributing sunlight and triggering cycles of ice build-up and melting. These changes shaped where water ice could survive on the planet’s surface. Over time, however, each cycle stored less ice, pointing to a gradual planetary drying. [emphasis mine]
You can read the paper here [pdf]. This result is not new. Based on the orbital data scientists have theorized now for almost a decade that as Mars’ rotational tilt (its obliquity) swings from 11 to 60 degrees, it produces extreme climate cycles on the planet. Those swings are shown on the graph to the right, taken from this 1993 paper [pdf]. When the obliquity is low, the mid-latitudes are warm and the glaciers there shrink, with the snow falling at the poles. When obliquity is high, the poles are warmer and its ice sublimates away to fall as snow in the mid-latitudes, thus causing those glaciers to grow instead.
The orbital data has consistently shown that with each new cycle, the glaciers grew less, suggesting that less global water was available on the planet. This new study further confirms these conclusions.
One last point: Though the amount of water ice on Mars has declined, we mustn’t think the red planet now has none. The orbital data shows that there is a lot of near surface ice on Mars, covering the planet from 30 degrees latitude poleward. As I’ve noted numerous times, Mars is a desert like Antarctica.
The orbital tug startup Momentus yesterday announced that NASA has awarded it two contracts worth $7.6 million total to fly two experimental NASA payloads on its Vigoride tug.
One payload will test “test the ability to make semiconductor crystals in microgravity”, while the second will “test a rotating detonation rocket engine, a propulsion system designed to provide higher efficiency than traditional engines.” In this case the propellants used will be nitrous oxide and ethane.
Both will fly on the same Vigoride tug on a mission to be launched no earlier than October 2026. Momentus also says there is room for additional payloads on that mission.
It appears the increase in the number and launches of rockets has actually hurt the orbital tug business:
Momentus is among several companies that developed orbital transfer vehicles, or OTVs, like Vigoride to ferry spacecraft between orbits. They are designed to provide last-mile delivery to specific orbits for spacecraft launched on rideshare missions such as [SpaceX’s] Transporter [launches]. However, demand for such services has been slower to materialize than expected. “Candidly, that part of the market has not developed as much as people thought, say, five years ago,” [said John Rood, Momentus’ chief executive] during a panel at World Space Business Week in September. “The reason is many small manufacturers are multi-manifesting satellites to deploy a single plane with a single launcher.”
As a result, Momentus has focused on getting technology demonstration contracts such as the two above, with the tug acting more like a service module.
Using archive data from the now retired Russian orbiting radio telescope RadioAstron, scientists have now obtained the first image of the binary supermassive black hole system OJ287 that was previously detected flaring as predicted when the smaller black hole (150 million solar masses) circled near the larger (18 billion solar masses).
That image is to the right, cropped and annotated to post here. The cartoon in the lower right shows the theorized orientation of the system, taken from figure 2 of the published paper [pdf]. According to the paper the elongation of the three objects is an artifact of the data and is “not real.” From the press release:
In this latest study, the astronomers compared the earlier theoretical calculations with a radio image. The two black holes were there in the image, just where they were expected to be. This gave the researchers an answer to a question that has been open for 40 years: whether black-hole pairs exist in the first place. “For the first time, we managed to get an image of two black holes circling each other. In the image, the black holes are identified by the intense particle jets they emit. The black holes themselves are perfectly black, but they can be detected by these particle jets or by the glowing gas surrounding the hole,” Valtonen says.
The researchers also identified a completely new kind of a jet emanating from a black hole. The jet coming out of the smaller black hole is twisted like a jet of a rotating garden hose. This is because the smaller black hole moves fast around the primary black hole of OJ287, and its jet is diverted depending on its current motion. The researches liken it to “a wagging tail” which should be seen twisting in different directions in the coming years when the smaller black hole changes its speed and direction of motion.
This image is cropped from the full dataset. The jet continues upward and then curves to the right as it “wags” away.
This incredible black hole binary system, estimated to be about 3.5 billion light years away, has been posited since 1982, when one astronomer noticed that it repeatedly flared every twelve years. Since then scientists have successfully predicted several flares, based on the system’s theorized orbit. These images further confirm the system’s shape.
Proposed Canadian spaceports
The Canadian rocket startup Nordspace, which earlier this week signed a deal for another company to establish ground stations for its proposed Atlantic Spaceport, today signed an agreement with the company Kongsberg Geospatial to provide software for running its mission control center.
According to the news release TerraLens “will ingest data from multiple sensors to deliver real-time three-dimensional (3D) visualization of launch operations, range safety, decision support, and vehicle tracking. This will help streamline launch operations and enable deployment of critical space missions to orbit in under 48 hours.” Kongsberg said TerraLens builds on their “experience supporting range safety and mission-critical visualization for the Andøya Space and Defence project in Norway.”
Andøya is Norway’s new commercial spaceport that has been launching suborbital government rockets for decades.
Nordspace continues to move forward quickly, having been established only three years ago. It is putting the pieces together for its spaceport, and is testing both a small suborbital rocket and the engines for its proposed orbital Tundra rocket. Though the race is certainly not over, it does appear Nordspace will get to orbit ahead of the Nova Scotia spaceport that was first proposed in 2016.
Billionaire Jared Isaacman
According to a report late today (based on anonymous sources), President Trump has held several face-to-face meetings in the past few weeks with billionaire Jared Isaacman, and those meetings have raised the possibility of Trump re-nominating him for NASA administrator.
According to Bloomberg News, President Trump has reportedly met with Isaacman several times in recent weeks to discuss NASA’s operational plans and future plans. Isaacman is the founder of fintech company Shift4 Payments and a private astronaut at SpaceX who has had a longstanding relationship with Elon Musk.
Isaacman, who has flown two private missions in space (and done one spacewalk), had been nominated by Trump for NASA administrator in December 2024, and was only days away from a Senate confirmation vote when Trump suddenly withdrew the nomination on May 31, 2025. Though it has never been clear why Trump withdrew the nomination, Isaacman’s past support of Democrats and his close links to Musk have been raised as issues, especially because of the Trump-Musk kerfuffle in the spring. Isaacman has also expressed some opinions since then about NASA and what it should do that might not have fit with Trump’s plans.
At the same time, NASA is presently without its own administrator, with Transportation Secretary Sean Duffy holding down the job as an interim head. It appears Trump might be reconsidering his earlier decision in order to get someone in charge of NASA who isn’t distracted by other responsibilities.
Note however that this report is solely from anonymous sources, and we all know how unreliable those are. The whole story could be fantasy cooked up by someone in DC for any number of devious political purposes.

The issues discovered in an audit of Maricopa County in Arizona
of 2020 election results. Note the problems found related to voting
machines, Dominion’s responsibility. The reason the “Ballots
Impacted” column is marked “N/A” (not available) is because
Dominion refused to cooperate. Click for full graph.
In what could be a major move towards election reform, the electronic voting system company Dominion — that many have suspected or have accused of either doing a bad job tabulating computer ballots or purposely manipulating them — has now been purchased by an American company dubbed Liberty Vote that is owned by Republican election reform activist Scott Leiendecker.
Leiendecker, former GOP election reform advocate, has officially become the sole owner of Dominion after making the deal contingent on dropping several remaining lawsuits against prominent conservatives and One America News Network (OANN).
Leiendecker further disclosed to the Caller that remaining litigation with MyPillow CEO Mike Lindell, former New York City Mayor Rudy Giuliani and former Trump campaign attorney Sidney Powell will be dropped by Dominion Voting Systems as part of the acquisition agreement. Dominion also filed a lawsuit against Herring Networks, which owns OANN, in August 2021. The lawsuit remained unresolved, though Leinendecker further confirmed that future litigation will be discontinued following the acquisition.
None of the charges against Dominion have ever been proven, and many have become impossible to investigate because the company’s very successful lawfare campaign, suing anyone who said anything against it, including news organizations such as Fox and Newsmax, both of which settled with Dominion, paying it $787 million and $67 million respectively. Nonetheless, the allegations have been numerous, substantial, and alarming (see also here, here, here, and here). Audits found errors, fraud, and the ability for outsiders to hack Dominion’s machines.
Leiendecker, in announcing the purchase, said that the new company will move all operations to the U.S. and will make third-party audits standard. It will also make paper ballots a fundamental component of its electronic tabulating system, something that Dominion did poorly or not at all.
Even if Dominion had been completely honest in its work, its resistance to investigation or even any criticism helped fuel the growing belief that the 2020 election of Biden was tampered with and might even have been fraudulent. That much of the company’s operations were foreign-based further fueled those suspicions. This purchase should help ease those concerns, though the proof will be in the pudding.

Cool image time! As most of the new cool images coming down from space seem mostly limited to Mars and deep space astronomy, I decided today to dig into the archive of the probe Cassini, which orbited Saturn from July 1, 2004 until September 15, 2017, when it was sent plunging into the gas giant’s atmosphere.
The picture to the right heralded the start of that mission, in that it was taken on February 19, 2004, a little over four months before the spacecraft fired its engines and entered orbit. I have rotated the image and cropped it to post here.
When Cassini snapped this picture it was just approaching the gas giant. The image itself is relatively small, with the resolution also relatively poor. You can see one of Saturn’s moons above the planet, but I can’t tell you which one. As noted at the webpage, this is a raw image that has not been “validated or calibrated.”
While not up to the amazing standard exhibited by Cassini’s images during its thirteen year stay at Saturn, it gave us a flavor of the wonders to come. Of all the planets, Saturn might be the most beautiful.
Though no final budget has yet been approved, based on the language in the budget the House has approved and sent to the Senate, only two of the seventeen on-going missions presently in space are specifically allocated money, thus allowing the Trump administration to zero out funding for the remaining fifteen.
The two missions saved are Osiris-Apex, on its way to the potentially dangerous asteroid Apophis, and the Magnetospheric Multiscale Mission (MMS), four satellites in orbit that observe the Earth’s magnetosphere.
The article at the link is typical of our propaganda press. It clearly opposes any cuts to NASA, and lobbies repeatedly for all funding to be reinstated. This pattern has gotten quite boring and tedious. It would be so refreshing to see a more objective take, at least one in a while.
However, its reporting confirms my own reporting from mid-September, where I noted that the vague language in the House budget bill would allow Trump to cut these missions. Congress wants to preen itself as supporting all funding for NASA, while carefully allowing Trump to go ahead with large cuts.
It is a good thing these two missions have been saved, though it does appear their funding has been trimmed. Of the fifteen missions in limbo, the only two that seem worth keeping is the Chandra X-Ray Observatory and New Horizons, though the second should likely be set up similar to the two Voyager spacecraft, with a very small crew aimed mainly at keeping the spacecraft functioning and able to send back data periodically.
We are in great debt. It is time that the federal government make some real choices. We can no longer afford to buy all the candy in the store.
Click for original. Blue indicates the basin, red
the “thorium-rich and iron-rich ejecta deposit”
While previous work had suggested the giant bolide that had created the Moon’s South Pole-Aitken Basin came in from the north, a new study now proposes that the impact was instead oblique from the south. From the paper’s abstract:
The ancient South Pole–Aitken impact basin provides a key data point for our understanding of the evolution of the Moon, as it formed during the earliest pre-Nectarian epoch of lunar history, excavated more deeply than any other known impact basin, and is found on the lunar far side, about which less is known than the well-explored near side. Here we show that the tapering of the basin outline and the more gradual topographic and crustal thickness transition towards the south support a southward impact trajectory, opposite of that commonly assumed. A broad thorium-rich and iron-rich ejecta deposit southwest of the basin is consistent with partial excavation of late-stage magma ocean liquids.
These observations indicate that thorium-rich magma ocean liquids persisted only beneath the southwestern half of the basin at the time of impact, matching predictions for the transition from a global magma ocean to a local enrichment of potassium, rare-earth elements and phosphorus (KREEP) in the near-side Procellarum KREEP Terrane.
In other words, when this impact occurred, part of the impact site in the south was still a magma ocean.
This result, if confirmed, has research implications for the missions targeting the Moon’s south pole. It suggests the geology will have that KREEP materials readily available, which will provide important information about the Moon’s early geological history.
The startup AST SpaceMobile, which is building a constellation of satellites able to act as cell towers for smart phones, has now signed an agreement with Verizon to give its subscribers access to the service.
AST SpaceMobile’s shares closed up more than 8% Oct. 8 after Verizon joined AT&T in signing a definitive agreement to use its planned space-based cellular network, easing investor concerns about SpaceX’s aggressive push into the fledgling direct-to-device (D2D) market.
The deal enables Verizon to provide D2D connectivity to its customers from some point in 2026, building on a strategic partnership announced in May 2024 that included plans for a $100 million investment in AST.
As noted above, AST has now signed both Verizon and AT&T, two of the largest cellphone companies, strengthening its position considerably in its competition with SpaceX’s Starlink cell-to-satellite alternative. Both deals appear to allow these companies the ability to sign contracts with both AST and Starlink, so it is possible the competition won’t be as fierce initially as it appears. It is also possible that eventually they will pick one or the other, so neither company should be complacent.
AST presently has five of its BlueBird satellites in orbit out of its planned 45-60 satellite constellation, and hopes to have at least half the constellation in orbit by the end of ’26. So even if it wins its cellphone competition with SpaceX that rocket company will still likely make some money launching AST’s satellites.

According to an analysis of pairs of 300 hundred orbital images taken seconds apart, scientist have found that Martian winds can reach speeds of 100 miles per hour (160 kilometers per hours), much faster than previously expected.
The results show that the dust devils and the winds surrounding them on Mars can reach speeds of up to 44 m/s, i.e. around 160 km/h, across the entire planet, which is much faster than previously assumed (previous measurements on the surface had shown that winds mostly remain below 50 km/h and – in rare cases – can reach a maximum of 100 km/h). The high wind speed in turn influences the dust cycle on the Red Planet: “These strong, straight-line winds are very likely to bring a considerable amount of dust into the Martian atmosphere – much more than previously assumed,” says Bickel. He continues: “Our data show where and when the winds on Mars seem to be strong enough to lift dust from the surface. This is the first time that such findings are available on a global scale for a period of around two decades.”
You can read the paper here. The study also found dust devils favor the spring and summer in both the north and south hemispheres, and tended to be concentrated in the mid-latitudes.
What is most interesting about this data, which because it is somewhat sparse has a lot of uncertainties, is that it suggests the candidate landing zone for SpaceX’s Starship is a region with one of the most intense dust devil seasons every spring and summer. This is not really a threat to settlement, because the atmosphere is so thin even these high winds would hardly be felt, but it does indicate an environmental condition that must be considered for any future settlement there.
For original images go here and here.
Cool image time! One of the geological mysteries on Mars seen no where on Earth is something scientists have dubbed “slope streaks.” Though they at first glance appear to be avalanches, they do nothing to change the topography, have no debris pile at their base, and sometimes even travel up and over rises on their way downhill. They can also appear randomly throughout the year, can be bright or dark, and fade with time.
No theory as to their cause has yet been accepted, though recent research suggests they are dry events, dust avalanches triggered by dust devils, wind, or the accumulation of dust.
To better understand this geology, scientists repeatedly monitor known slope streak locations looking for changes. The two images to the right are an example, downloaded from the high resolution camera on Mars Reconnaissance Orbiter (MRO) on July 2, 2024 and September 1, 2025. In the fourteen months that passed between the first and second images, two distinct and large slope streaks occurred next to each other, near the bottom of the picture. All the other streaks merely faded.

Proposed Canadian spaceports
The Canadian rocket startup Nordspace has signed an agreement with the ground station company C-Core to establish more tracking and communication facilities in conjunction with Nordspace’s launch plans at its Atlantic spaceport in Newfoundland.
NordSpace and C-CORE have signed a Memorandum of Understanding (MOU) that will see the companies work together in developing new ground stations across Canada with initial locations planned for the Atlantic Spaceport Complex (ASX) in St. Lawrence, Newfoundland and Labrador, and Inuvik, Northwest Territories.
With C-CORE being based in St. John’s, Newfoundland, and already established in providing ground station services, it seems like a natural collaboration that could benefit both companies. For NordSpace, which owns and is developing the Atlantic Spaceport Complex, this collaboration provides the potential for another type of revenue source as the company tries to diversify.
Nordspace has not yet launched, though its first suborbital test launch several weeks ago was scrubbed twice due to ground equipment fuel leaks. It has not yet announced another date for that suborbital test, but plans a static fire test in October of the engine it is building for its orbital Tundra rocket.
This company is only three years old, and appears to have leap-frogged past Canada’s other spaceport operation in Nova Scotia, which has been trying to get off the ground for almost a decade.
