New orbital radar data confirms large ice deposits in Phelgra Mountains near Starship landing zone

3:18 pm

Overview map

A new paper published this week used the SHARAD radar instrument on Mars Reconnaissance Orbiter (MRO) to confirm that the glacial features found everywhere within the Phlegra Mountains where one of Starship’s four prime landing sites is located contains significant quantities of very accessible pure water ice.

The red dots on the map to the right mark two of those prime landing sites, with one inside the Phelgra Mountains in a region directly studied by this paper. The numbered black dots were other images taken by MRO for SpaceX, reported here in 2020. From the paper’s abstract:

We examined mid-latitude landforms on Mars that resemble Earth’s debris-covered glaciers in a region called Phlegra Montes. Our study site is a 1,400-km-long mountain range in the northern hemisphere of Mars that houses numerous debris-covered glaciers also called Viscous Flow Features (VFFs). Using data from the SHallow Radar (SHARAD) instrument, we detected eight new glaciers and estimated the thickness and volume of ice within them as well as the thickness of the debris on top insulating the ice. Our findings suggest that the region holds around 1.2 trillion cubic meters of ice below the surface. We detected two notable types of glaciers for the first time on Mars using SHARAD: (a) a glacier system with terrace-like steps and (b) a perched “hanging” glacier on the eastern side of the mountains

The study also found that the layer of dust and debris that covers these glaciers and protects them from sublimating away ranges from 6 to 25 feet in thickness, well within reach of any future colonists.

This study only confirms what all the orbital data for the past two decades has suggested, that Mars is an icy world like Antarctica, not a dry desert like the Sahara. As the researchers themselves note in the very first line of their paper, “Mars is a frozen world where water ice is abundant above, at, and under the surface.”

Their research also confirms that SpaceX has made a good choice for its Starship prime landing sites. Though it will likely not make its first landing at site #3, because it is inside the mountains and thus more risky, expect a landing there not long thereafter.

SpaceX: Starship will be going to the Moon, with or without NASA

12:27 pm

Click for original.

In what appears to be a direct response to the claim by NASA’s interim administrator Sean Duffy that SpaceX is “behind” in developing a manned lunar lander version of Starship, SpaceX today posted a detailed update of the status that project, noting pointedly the following in the update’s conclusion:

NASA selected Starship in 2021 to serve as the lander for the Artemis III mission and return humans to the Moon for the first time since Apollo. That selection was made through fair and open competition which determined that SpaceX’s bid utilizing Starship had the highest technical and management ratings while being the lowest cost by a wide margin. This was followed by a second selection [Blue Origin’s Blue Moon lander] to serve as the lander for Artemis IV, moving beyond initial demonstrations to lay the groundwork that will ensure that humanity’s return to the Moon is permanent.

Starship continues to simultaneously be the fastest path to returning humans to the surface of the Moon and a core enabler of the Artemis program’s goal to establish a permanent, sustainable presence on the lunar surface. SpaceX shares the goal of returning to the Moon as expeditiously as possible, approaching the mission with the same alacrity and commitment that returned human spaceflight capability to America under NASA’s Commercial Crew program.

The update then provides a list of the testing and engineering work that SpaceX has been doing on the Starship lunar lander, including full scale drop tests simulating lunar gravity, qualification of the docking ports, and the construction of a full scale mock-up of the Starship cabin to test its systems.

A close list of the work done is actually not that impressive, but at the same time this is not surprising. SpaceX is now mostly focused on getting Starship into orbit, proving it can be refueled there, and proving it can fly for long enough to get to the Moon. This part of the update was most exciting, as it confirms what I have suspected for next year’s flight program:

Colorado sues the Trump administration over its decision to move Space Force headquarters to Alabama

11:47 am

The Democratic Party attorney general of Colorado yesterday announced he is suing the Trump administration over its decision to relocate the headquarters of the Space Force from Colorado Springs to Huntsville, Alabama.

Colorado Attorney General Phil Weiser is suing President Donald Trump’s administration over its “retaliatory” decision to relocate U.S. Space Command from Colorado Springs to Huntsville, Alabama.

In a lawsuit filed in the U.S. District Court of Colorado on Wednesday, Weiser wrote that the president “could not have been clearer about his motivations” for the move, citing Trump’s comments during the Oval Office announcement last month acknowledging that Colorado’s elections, which he falsely described as “crooked,” were a “big factor” in his decision.

That admission makes Trump’s decision to vacate Space Command’s temporary location in Colorado — the latest twist in a years-long battle over the permanent home of Space Force headquarters — an unconstitutional violation of state sovereignty, Weiser said in a press conference. “The executive branch isn’t allowed to punish, retaliate, or seek to coerce states who lawfully exercise powers that are reserved to them,” Weiser said. “And that includes the power to oversee the time, place and manner of elections.”

Weiser’s lawsuit has little chance of winning in court. No state can tell the federal government where to place its facilities, no matter what the reason. The suit is mainly a crumb Weiser is throwing to his local Democratic Party supporters, showing them he as is equally controlled by Trump Derangement Syndrome as they are.

I should note that I also strongly disagree with Trump’s decision in this case. It will cost a lot of money, and will gain us nothing. The military’s space operations have been based in Colorado for more than a half century. Though a major reorganization of this bureaucratic structure is warranted, it would be far better to reorganize it there, rather than try to recreate it elsewhere.

Roscosmos forced to replace next manned Soyuz capsule due to damage during test

11:38 am

Russia’s space agency Roscosmos has replaced the Soyuz capsule it was going to use in the next manned mission to ISS, scheduled for launch in late November, because of “major damage” the capsule experienced during normal pre-flight testing.

[D]uring routine post-production tests at ZEM’s Checkout and Test Facility, KIS, Vehicle No. 759 reportedly suffered major damage to its thermal protection system, which could not be repaired in time for the Expedition 74 launch at the end of 2025. According to one source, quoting an officer within the military certification service, Voennaya Priemka, which traditionally oversees quality control in the Russian rocket and space industry, the ship’s main thermal control heat shield, attached to the base of the Descent Module, was accidentally jettisoned, perhaps by a stray signal triggering the pyrotechnic bolts, connecting the Frisbee-shaped structure to the capsule. According to another source, the thermal layers of the shield peeled off, as a result of botched thermal tests.

That Russia can quickly swap capsules this late in the game speaks well of its Soyuz capsule manufacturing process. It doesn’t just build one or two capsules, it has an assembly line.

That the capsule was damaged during the test however once again raises questions about the overall quality control within the Russian space industry, as well as the reliability of its workforce. It has been building Soyuz capsules now for more than a half century, during which it has steadily implemented upgrades along the way. For there to be “a stray signal triggering the pyrotechnic bolts” during routine testing is disturbing. The circumstances are too similar to the earlier sabotage to both Progress and Soyuz capsules, where the evidence suggested someone on the ground had drilled holes in their hulls prior to launch, then patched them to hide their existence until later while in orbit.

Under Putin the living wages of Russian engineers has suffered. It remains a distinct possibility that there are more than a few malcontents within Roscosmos willing to do such stuff. That Roscosmos investigated the previous sabotage, claimed it identified the cause, but refused to release any information about its conclusions, suggests strongly that this is what what happened in those earlier cases. This new incident in turn raises the possibility now of further sabotage.

It once again is critical that the U.S. get out of its space station partnership with Russia as soon as possible. There are too many known and unknown risks.

A slew of propaganda today from China’s state-run press attempts to hide the delays in its manned lunar program

10:27 am

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

Generally China’s state-run news agency Xinhua posts no more than one to two short space-related articles per day, with most confined to simply announcing the launch of a rocket.

Today however that state-run agency posted a dozen short articles, linked it appeared to the two press conferences held in connection with tomorrow’s launch of a new crew to China’s Tiangong-3 space station.

The list above is not complete, leaving out a few other short propaganda pieces. Some of these stories — such as those directly related to that new crew launch tomorrow — could have easily been folded into one report. They were not, however, in order to create a large number of separate reports, which in turn hides the fact that there is only one news outlet reporting anything from those two press conferences.

Out of this plethora of stories, two news items stand out however. One, China has now agreed to fly a Pakistani to Tiangong-3. Negotiations for that mission began in 2018. Training has now finally begun. China is also moving forward on flying astronauts from Hong Kong and Macao, two places formally run by western powers that China now controls, quite oppressively. Like the Soviet Union, it is using its space program for propaganda stunts to distract those regions from its iron rule.

Second and more important, Chinese officials claim their program to do a manned lunar landing is still on schedule for a 2030 launch.

AST SpaceMobile signs 10-year deal with Saudi Arabia

9:22 am

The American satellite startup AST Spacemobile yesterday signed a ten year $175 million deal with Saudi Arabia’s telecommunications company STC to use is Bluebird satellite constellation provide its phone-to-satellite service to Saudi Arabia.

AST SpaceMobile will integrate its space-based cellular broadband connectivity with stc’s terrestrial infrastructure to expand mobile coverage across Saudi Arabia, as well as select countries in the Middle East and Africa. The partnership aims to eliminate connectivity gaps by delivering 5G and 4G LTE services directly to standard mobile phones without the need of any specialized software or device support or updates, for consumers, enterprises, and government sectors, ensuring seamless voice and broadband access

Under this agreement, the first in the region for AST SpaceMobile, the company will build three ground gateways in Saudi Arabia and establish a Network Operations Center (NOC) in Riyadh to support the network’s operations and service quality. These key infrastructure developments will be instrumental in providing seamless connectivity across the region.

In many ways, this company is the only one that is succeeding in a direct competition with SpaceX. Both companies are launching satellites designed to act as orbiting cell towers for smart phones. Both are now operational to about the same extent. And both are winning contracts in the U.S. and internationally.

With rocketry however no one else is even close to SpaceX. It is a decade since it introduced reusability in rockets, and still no one else has done it. And as for its Starlink internet satellite constellation, only now, five years after that constellation’s first launch, are other satellite constellations beginning to launch. Its 5,000-plus constellation exceeds all other constellations combined.

AST is not only competing with SpaceX, it might even be winning. For that the company deserves great kudos indeed.

Lawsuit against Amazon for favoring Blue Origin over SpaceX to launch Kuiper satellites gets new hearing

8:01 am

The lawsuit originally filed in 2023 against Amazon because it favored other less reliable rockets, including Blue Origin’s forever-delayed New Glenn, instead of using SpaceX to launch its Kuiper constellation of satellites, got a new hearing yesterday after the suit was dismissed in February.

The suit is now being pursued a pension fund that apparently invested in the Kuiper constellation, and claims Jeff Bezos used his influence to convince Amazon to avoid using SpaceX when it signed launch contracts with ULA, Arianespace, and Blue Origin in 2022, even though none of those rockets were even operational at the time. Even now they appear unable to meet Amazon’s launch requirements.

Amazon has until 2026 to send up the first 1,600 satellites and three more years to launch the next batch. That broader backdrop barely came up during the appeal proceedings, which zoomed in on allegations that the board made no effort to oversee self-dealing by Bezos as he directed billions from Amazon to his own rocket company, Blue Origin, despite SpaceX’s superior capabilities.

Vivek Upadhya, counsel for the pension fund, stressed the “billions of dollars flowing directly from Amazon to a company owned and controlled by Amazon’s CEO and chairman.” The sheer scale of the conflict of interest made the Blue Origin contract “a truly exceptional transaction” requiring attentive board supervision, regardless of the actual role Bezos played in negotiations, according to Upadhya. “Delaware law doesn’t require that directors harbor some innate suspicion” before taking steps to manage conflicts, but the board “failed to lift a finger,” he said.

Following the filing of the 2023 lawsuit, Amazon signed SpaceX to a three-launch contract, which SpaceX has now completed. Meanwhile, only ULA has managed any of the other launches, three also. As for Arianespace and Blue Origin, it is not clear when either will begin doing any Kuiper launches.

It does appear Amazon’s board played favorites here, and did so in a way that was harmful to the company’s bottom line. Whether this can be proved to the satisfaction of the court however is very uncertain.

“Weird Al” Yankovic – Smells Like Nirvana

6:01 pm

An evening pause: A parody of “Smells like Teen Spirit,” according to the webpage, but as far as I am concerned it is a very funny parody of most “official” music videos, the kind I generally don’t like to post as evening pauses because, as Yankovic says in the first verse:

What is this song all about?
Can’t figure any lyrics out
How do the words to it go?
I wish you’d tell me, I don’t know

It gets better from there.

Hat tip Alan Hennings.

  • Shutdown could soon slow preparations for Artemis 2
    The sole source of this story is an official at Lockheed Martin, which makes Orion. That company has gotten since 2005 about $25 billion from NASA to build it, has made less than a half dozen capsules total, and has produced a capsule with an untrustworthy heat shield that still has an untested environmental system. For this company to say the shut down will impact its work is disgusting.
  • A new Chinese pseudo-company Zenkspace to launch their ZH-1 rocket in early 2026
    Jay notes there is zero information about this company on the web. According to another tweet, the rocket’s engines were supplied by the Chinese government. Suggests to me that someone in that government is moving in to grab the business from the other Chinese government-controlled startups, essentially taking advantage of government infrastructure while stealing the engineering from those pseudo-companies (that the government requires them to release to everyone).
  • On this day in 2009 Ares-1x made its only flight
    It was only suborbital, and was supposed to lay the groundwork for NASA’s manned return to the Moon by 2015, as part of the program established by President George Bush Jr. It instead morphed into the never-ending boondoggle that has become SLS, Orion, and the entire Artemis program. And it now 2025, and we are still at least three-plus years from that manned lunar landing.

The alien landscape of Mars’ north polar ice cap

The strange terrain of Mars' north polar ice cap
Click for original image.

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

The camera team labels this simply as a “terrain sample,” which usually means it was not taken as part of any specific research request, but to fill a gap in the camera’s schedule in order to maintain its proper temperature. When they need to do this, they try to find interesting things to photograph, and mostly succeed.

At first glance the picture to the right does not appear that interesting. If anything it shows an endless expanse of mottled terrain, with no features of any interest at all. This sameness however is what makes this picture and landscape intriguing. What caused it to look this way?

SpaceX launches 29 Starlink satellites

9:43 am

SpaceX once again broke its annual record for successful launches today, placing 29 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage completed its 15th flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

141 SpaceX (a new record)
65 China
13 Russia
13 Rocket Lab

SpaceX now leads the rest of the world in successful launches, 141 to 107. The U.S. launch total in 2025, now 159, is also a new record.

Blue Origin officials provide update on their lunar lander program

9:30 am

2023 artist rendering of the manned Blue Moon lander
2023 artist rendering of the manned Blue Moon lander

Link here. According to the article, the company is presently stacking its first unmanned version of its Blue Moon lander, dubbed Blue Moon Mark 1, scheduled for launch now next year.

The 8.1-meter-tall cargo lander will help with ongoing development of their crewed lander, named Blue Moon Mk. 2, which is 15.3 meters tall. Both are powered by Blue Origin’s BE-7 engines, which are being tested on stands in Alabama, Texas and Washington.

…“A big milestone for you to look out for online is that Mk. 1 is three modules that are being stacked as we speak: aft, forward and mid. And once it is stacked in its finished configuration, we will be barging it over to NASA Johnson Space Center Chamber A to do a full up thermal vac campaign,” said [Jacqueline Cortese, Blue Origin’s Senior Director of Civil Space]. “So when you see that on its boat, you will know that big things are happening.”

Both versions of the lander are powered by a combination of liquid hydrogen and liquid oxygen. A key difference though is that Mk.1 can be launched to the Moon with a single launch of Blue Origin’s New Glenn rocket while Mk. 2 requires orbital refueling. [emphasis mine]

The highlighted sentence above is important because it illustrates the absurdity of the comments last week by interim NASA administrator Sean Duffy, claiming SpaceX’s program to make Starship a manned lunar lander is “behind”, forcing him to open up the competition to Blue Origin, who might get it done sooner.

One of the big issues used against SpaceX is that Starship will need to be refueled once in orbit to work as a lunar lander, and that technology needs to be developed and tested. The problem with this criticism is that, as noted above, Blue Origin’s manned lunar lander also needs to be refueled.

Startup semi-conductor manufacturer Besxar signs deal to use SpaceX’s Falcon 9 first stage as production platform during its short flight

8:57 am

In what appears to be first, the startup Besxar has signed a deal with SpaceX to fly what it calls its Fabships on the first stage of the Falcon 9 in order to take advantage of the extreme vacuum of space to produce better semi-conductors.

Fabships will be integrated on Falcon 9 first stage boosters and retrieved post launch after the rocket safely returns to land. The campaign marks the first-ever reusable payload program to launch on a SpaceX rocket and will accelerate Besxar’s path toward building the world’s first orbital semiconductor foundry. This flight campaign will debut Besxar’s “Clipper-class” Fabship, engineered for short-duration, quick-turnaround sorties that enable rapid iteration and demonstrate the first phase in Besxar’s broader vision to establish scalable semiconductor production in orbit.

Besxar is pioneering a new class of orbital manufacturing, using the ultra-high vacuum (UHV) of space to produce ultra-pure substrates and precursor materials—the foundational building blocks for AI data centers, quantum computing, nuclear systems, next-generation defense systems, and directed-energy applications. By manufacturing in orbit, Besxar can achieve purity levels and yield efficiencies impossible on Earth, effectively doubling the chip cost-efficiency for next-generation AI workloads.

The deal is for twelve flights, with the first occurring as soon as this year. The deal not only allows Besxar an opportunity to produce a better product it can sell, it gives SpaceX another avenue for profits. It is in fact surprising that SpaceX has not done more deals like this, especially with its Dragon cargo capsule. There is a whole cottage industry now developing using returnable capsules for in-space manufacturing — led by Varda. That SpaceX hasn’t offered Dragon as yet is puzzling. It is possible Dragon is simply too expensive and large at this time, based on the nascent state of this industry. Once investors see profits from the smaller new capsules like Varda’s they will look at Dragon as an option.

Lockheed Martin completes first flight of X-59 supersonic test plane

8:32 am

My heart be still: Lockheed Martin yesterday completed the first flight for NASA of the X-59 supersonic test plane, designed to produce a much quieter sonic boom.

The X-59 took off from Skunk Works’ facility at U.S. Air Force Plant 42 in Palmdale, California, before landing near NASA’s Armstrong Flight Research Center in Edwards, California. The X-59 performed exactly as planned, verifying initial flying qualities and air data performance on the way to a safe landing at its new home.

The plane did NOT yet fly at supersonic speeds. It needs to do more flight tests before it attempts that feat. A somewhat uninteresting video of the flight can be seen here. (Hat tip to Jay.)

This NASA program is another example of government waste. NASA issued the company a $247.5 million the contract for this test plane in 2018, after two years of preliminary design work. Seven years later it finally flies once, but not at supersonic speeds.

Meanwhile, the commercial startup Boom Supersonic started at about the same time, raised far less investment capital, and successfully flew a supersonic flight in January 2025 in which it broke that sound barrier three times, with no audible sonic boom.

Boom has already obtained numerous contracts with the airline companies United and Japan Airlines to provide them planes. It is in the process of manufacturing its Overture commercial passenger jet for sale.

Lockheed Martin’s NASA project has no investors and no airlines interested in the test plane. Lockheed Martin itself is not marketing it and has no plans to use the technology commercially. In fact, NASA likely forbids it from doing so.

I am sure these tests will provide data helpful to Boom and the handful of other commercial supersonic startups. At the same time, the entire project is another example of a poor use of taxpayer funds.

The base of the Democratic Party has truly become nightmare to behold

12:25 pm

They aren't just mindless, they are driven by hate
They aren’t just mindless, they are driven by hate

I always say it is the audience that counts. No matter what idiocy the leaders on both sides of the political spectrum might propose, the real future is determined by what their base wants.

It is now very clear that the base of the Democratic Party is driven entirely by hate, envy, and a lust for power, based on an ignorance of history that is appalling. And my saying this not simply an opinion. It is founded on what that base itself has said repeatedly in the past year. First that base has increasingly thrown its support behind Hamas and its anti-Semitic hate of Israel and Jews. Next, it mourned the failed assassination attempts against Donald Trump, then celebrated the murder of Charlie Kirk, a man whose primary goal was to foster free debate.

In this election season now that base is supporting a candidate in Maine, Graham Platner, who got a Nazi tattoo placed on his chest, and has made numerous hateful posts online over the years against anyone who disagreed with him.
In Virginia that base is excited to support a candidate for attorney general, Jay Jones, who enthusiastically called for the murder of his political opponents as well as the death of their kids.

And finally, in New York that base is rallying with great joy around an anti-Semitic Muslim, Zohran Mamdani, who hates the police and wishes to impose communism on that city. And the base showed its envy of the success of others at a big Mandani rally this past weekend, chanting without prompting over and over again that Mandani and New York’s Democratic Party governor Kathy Hochul should “Tax the rich!”

It was very clear that they weren’t chanting this to simply to re-distribute wealth, or to improve New York. No, it was very clear they wished to tax the rich because they wanted to destroy the rich. How dare such people have success when I don’t!

European think tank pushes passage of proposed and very Byzantine space law

10:51 am

The European Union
This label would be more accurate if it read
“NOT made in the European Union”

A European think tank, the Centres for European Policy Networks (CEP), today released its analysis of a proposed space law it wants the European Union to adopt during its on-going fall session.

The Commission’s draft seeks to harmonize national regulations and establish common safety standards. According to the CEP, this is necessary to ensure a level playing field for space activities in the European single market.

This law was first released in June 2025. In reviewing it then, I concluded it would be a disaster for Europe should it be approved.

It imposes new environmental, safety, and cybersecurity regulations on the design of satellites and spacecraft in a manner that will likely slow development and competition in Europe significantly. And it applies these regulations not only to European companies but to the rest of the world’s space industry, should it do any operations at all in Europe.

CEP’s policy analysis [pdf] confirms my assessment, but thinks it is a great idea, especially its provisions that impose its rules on other countries.

In this context, the EU Space Act aims to extend the EU’s jurisdiction to space service providers based outside the EU who offer space-based data or services within the Union. This approach would ensure that no space operator is given an advantage by being exempt from the rules and prevents the circumvention of EU regulations. [emphasis mine]

In other words, the EU must rule everyone! What will instead happen if this law is passed is that American companies will simply refuse to do business with Europe. I can guarantee that SpaceX will pull its Starlink business from Europe if the EU tries to impose these regulations on it.

Europe meanwhile will find its own space industry hobbled trying to meet the law’s many odious regulations.

That the EU is still considering this law is remarkable in itself. The law was first proposed in 2024, but the vote on it was delayed a year when a number of EU members opposed it vehemently. Those nations all want their own nascent home-grown space industries to prosper, and see this law as bad policy that will kill them.

Whether that opposition can stand up to the globalist desires of the EU and Europe’s bureaucratic culture however remains very uncertain.

SpaceX settles Cards Against Humanity lawsuit against it

9:26 am

Though no monetary numbers have been released, its appears Cards Against Humanity (CAH) has settled its $15 million lawsuit with SpaceX, instigated when the company illegally stored equipment on a piece of land CAH had purchased in 2017 in an effort to block Trump’s border wall.

Per AP, according to Texas court records, a settlement was finalized last month, prior to the upcoming Nov. 3 jury trial marked on the calendar. SpaceX owns other land plots in the Brownsville, Texas area in Cameron County, but apparently had no right to use this patch.

“The upside is that SpaceX has removed their construction equipment from our land and we’re able to work with a local landscaping company to restore the land to its natural state: devoid of space garbage and pointless border walls,” CAH wrote in a recent message to customers. “Were we hoping to be able to pay all our fans? Sure. But we did warn them they would probably only be able to get like $2 or most likely nothing.”

Based on a somewhat childish and obscene statement from CAH describing the settlement, it got little additional money from SpaceX. The company admitted its trespass, agreed to pay for the restoration, but agreed to nothing else. In response, CAH says it will issue a free new set of cards “all about Musk” to those who donated to buy the land. The tone of CAH suggests the cards will be equally childish and obscene.

As for the border wall, if the Trump administration decides it wants to build it across this piece of land, CAH’s ownership won’t make any difference. The Trump administration will simply initiate eminent domain proceedings to take the land.

Voyager Space buys satellite electric propulsion company Exoterra

9:04 am

Voyager Space announced yesterday that it has acquired Exoterra, a company that specializes in building electric propulsion engines for satellites.

ExoTerra’s proprietary technology delivers precise maneuvering, extended lifetimes and high efficiency delta-V – essential for spacecraft across national defense architecture layers that must be able to reposition, avoid threats and sustain mission advantage.

…ExoTerra’s Halo thruster technology is proven aboard DARPA Blackjack ACES spacecraft and the company recently supplied York Space Systems with 21 propulsion modules for the Space Development Agency Transport Layer. The company also has contracts with commercial companies and organizations such as NASA.

Voyager Space began as a space station startup, acting as the lead company in the consortium building the Starlab station. Since then it has diversified its operations to make money in other space-related areas. This acquisition appears aimed at increasing Voyager’s ability to win contracts in connection with the military’s Golden Dome project.

The Philippines and Malaysia sign Artemis Accords

8:55 am

As part of a number of diplomatic agreements signed during President Trump’s visit to Malaysia this week, the State Department announced that both the Philippines and Malaysia have also added their names to Artemis Accords, bringing the number of nations in the American space alliance now to 59.

The full list of nations who have signed the accords: Angola, Argentina, Armenia, Australia, Austria, Bahrain, Bangladesh, Belgium, Brazil, Bulgaria, Canada, Chile, Colombia, Cyprus, Czech Republic, Denmark, Dominican Republic, Ecuador, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, India, Israel, Italy, Japan, Liechtenstein, Lithuania, Luxembourg, Malaysia, Mexico, the Netherlands, New Zealand, Nigeria, Norway, Panama, Peru, Poland, Romania, Rwanda, Saudi Arabia, Senegal, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, Thailand, the Philippines, the United Kingdom, the United Arab Emirates, the Ukraine, the United States and Uruguay.

The State Department tweet announcing this agreement says it the nations “are committed to principles of safe and transparent space exploration,” a relatively meaningless statement. It remains unknown whether Trump will use this alliance to get around the Outer Space Treaty’s restrictions on private property in space, as the original goal of the accords appeared to be during Trump’s first administration. So far it appears Trump is largely uninterested in this subject in his second term.

If this is so, then it is possible this alliance in future years would actually act to limit freedom in space. Despite its founding under the concept of constitutional limited rule, the culture of the American government has been quite hostile to this concept in recent decades. We cannot be confident it will support freedom and limited government in the future, on Earth or in space. And because future colonists will have less leverage on Earth, expect that government to be more abusive to those distant space-farers.

It is up to Trump to fix this. He has the opportunity to set precedents that could shape the future in space significantly. It remains very unclear whether he realizes this.

According to claims coming from Russia’s state-run press yesterday, it has successfully tested a low-flying nuclear-powered cruise missile, dubbed Burevestnik (“Storm Petrel” in English), that uses a nuclear-powered rocket engine.

Few technical details have been released. The flight itself supposedly lasted fifteen hours during which the missile flew about 8,700 miles, making its average speed about 580 miles per hour. That speed is a little higher than the cruising speed of most airplanes. According to Russia’s state-run press, Burevestnik flies at an altitude of 80 to 300 feet and has an unlimited range.

It appears the missile captures air as it flies, compresses it and then sends it through the nuclear reactor to be heated, which when released as exhaust provides the thrust. If true, this missile is the equivalent of an autonomous airplane that can fly below radar detection anywhere on the globe, and thus a major threat to Russia’s enemies (which is essentially now the whole world).

At the same time, Russia’s ability to design, build and complete any high-tech project has been suspect for decades. Its government makes a lot of promises, but has almost never delivered.

Regardless, this technology bears watching. Expect the defense industry to use this story as a wedge with Congress to get more funding.

New data supports theory of dark matter, but suggests inexplicably that it acts differently depending on the galaxy’s mass

9:13 am

The uncertainty of science: Astronomers analyzing twelve small and faint galaxies have determined that the existence of some form of mysterious undetected dark matter is necessary to explain the motions of their stars, and that another theory dubbed MOND that would make dark matter unnecessary fails to explain the data.

The authors found that the galaxies’ internal gravitational fields cannot be explained by visible matter alone, and that MOND predictions fail to reproduce the observed behaviour. They then compared their results with theoretical models that assume instead that these galaxies are surrounded by a massive halo of dark matter. Run on the UK’s DiRAC National Supercomputer facility, these dark matter models gave a much better match to the data.

Sounds good, eh? Not so fast. The research also found that large and small galaxies inexplicably interact with gravity and dark matter differently.

The research, published in Astronomy & Astrophysics, also challenges a long-standing assumption about how galaxies behave. Astronomers have long believed there is a simple link between the amount of visible matter in a galaxy and the strength of the gravitational pull it produces – known as the “radial acceleration relation.” While this relationship still holds for larger systems, the new study shows that it starts to break down in the smallest galaxies.

In other words, we don’t know enough yet to really explain the formation and behavior of galaxies. This really isn’t surprising, considering the time scales involved (billions of years) and the distances (millions to billions of light years).
