Genesis cover

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, any other book seller, or direct from my ebook publisher, ebookit. 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.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"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

Meandering channels on Mars

Meandering channels on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 2, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The scientists describe this as “meandering channels,” which seems appropriate. The downhill grade here is to the southeast. In wider views these channels extend from the northwest to the southeast about 31 miles total (with this location near the center), with the total elevation loss about 3,000 feet.

Note the splash apron around the 4,500-foot-wide unnamed crater as well as how the largest channel seems to terminate suddenly at the crater. Though at first glance it appears this impact occurred after the channels, that some of the channels cut into that splash apron suggests otherwise.

Expect fewer and less violent protests should Trump win

11:46 am

Nazi brown shirts destroying Jewish businesses on Kristallnacht
No more American Kristallnachts

Based on recent events, I am willing to predict that we shall see much less violence than expected in the days after the election should Donald Trump win. And if those protests occur, they will mostly be concentrated in Democratic Party strongholds where the protesters feel reasonably confident they can get away with it.

I base this optimistic prediction on the trends we have been seeing. As I first noted in April 2024, the strength of these leftist protests has clearly lost steam in the last four years. While in 2020 the protests and looting and violence occurred almost everywhere, destroying many inner cities, in the last year those protests have mostly been confined to college campuses, and have resulted in relatively little damage in comparison.

The reasons have been two fold. First, the authorities, while still generally treating these protesters too gently, have still responded more aggressively. Violent protesters are now arrested. Some face prison terms. Faced with real consequences, this violent leftist protest movement can no longer get the same numbers to turn out.

Second, the protests and violence has declined because of the utter failure of these protests to work. If anything, the looting and destruction has convinced vast numbers of Americans to oppose the left and to now vote with even greater energy against the politicians who support it.

Thought trends have been obvious for months, recently we have had even more evidence that the protests and violence will be less should Trump win. And that evidence is striking.

Astronomers call for the FCC to halt all launches of satellite constellations

9:50 am

In a letter [pdf] sent to the FCC on October 24, more than one hundred astronomers demanded a complete halt of all launches of low-Earth satellite constellations until a complete environmental review can be done.

The environmental harms of launching and burning up so many satellites aren’t clear. That’s because the federal government hasn’t conducted an environmental review to understand the impacts. What we do know is that more satellites and more launches lead to more damaging gasses and metals in our atmosphere. We shouldn’t rush forward with launching satellites at this scale without making sure the benefits justify the potential consequences of these new mega-constellations being launched, and then re-entering our atmosphere to burn up and or create debris This is a new frontier, and we should save ourselves a lot of trouble by making sure we move forward in a way that doesn’t cause major problems for our future.

Under this premise, Americans would forever be forbidden from doing anything without first having detailed environmental reviews by federal government agencies. Ponder that thought for a bit.

The astronomers’ argument of course is intellectually dishonest and disingenuous, on multiple levels. It is more than evident that these launches and satellites will cause little serious harm to the atmosphere or the environment. What the astronomers really want is to block these constellations so that their ground-based telescopes will be able to continue to see the heavens unhindered.

To hell with everyone else! We need to gaze at the stars and we are more important!

What these Chicken Littles should really do is give up on ground-based astronomy entirely, and start building space-based telescopes of all kinds, and fast. They would not only bypass the satellite constellations, they would get far better data as they would also bypass the atmosphere to get sharp images of everything they look at.

Whether the FCC listens to this absurd demand depends entirely on who wins the election. A Harris administration might easily go along, shutting down not only SpaceX’s Starlink constellation (thus getting political revenge on Elon Musk for daring to campaign against Democrats) but Amazon’s Kuiper constellation as well. Such an action would likely exceed the FCC’s statutory authority, but that won’t matter to these power-hungry thugs.

Trump in turn would almost certainly shut down much of the administrative state’s mission creep into areas of regulation it has no legal business.

Parker to make its last fly-by of Venus

9:33 am

The Parker Solar Probe is scheduled to complete its last fly-by of Venus on November 6, 2024, passing only 233 miles above the planet’s surface.

The flyby will adjust Parker’s trajectory into its final orbital configuration, bringing the spacecraft to within an unprecedented 3.86 million miles of the solar surface on Dec. 24, 2024. It will be the closest any human made object has been to the Sun.

That close solar approach will occur on December 24, 2024. Whether the spacecraft can survive is the main question, and we won’t find out until three days later, when it sends a signal to confirm its survival. If successful, it will then attempt to repeat that close fly-by at least two more times.

As for the Venus fly-by, the spacecraft will use one instrument to attempt to peer into Venus’s clouds.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

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

WISE/NEOWISE burns up in the atmosphere

9:22 am

NASA’s Wide-field Infrared Survey Explorer (WISE, later renamed NEOWISE) has ended its fifteen years in orbit, burning up in the atmosphere on November 1, 2024.

In its initial mission it did an infrared survey of the sky, discovering millions of black holes, many of the most luminous galaxies, and numerous brown dwarfs. It was then repurposed to survey the sky for near Earth objects, asteroids that have the potential to impact the Earth, discovering more than two hundred new asteroids while tracking more precisely another 3,000. It did this by repeating its survey over and over so that moving objects could be spotted.

Three launches last night

9:10 am

Last night three different rockets took off from three continents.

First, Russia launched two space weather satellites and 53 cubesats, its Soyuz-2 rocket lifting off from its Vostochny spaceport in the far east. The main payload were the two Ionosfera-M satellites, designed to study the Earth’s ionosphere in tandem.

The rocket flew north, over Russia, where its lower stages were dropped into planned drop zones. No word if they crashed near habitable ares.

Next, SpaceX launched an unmanned cargo Dragon to ISS, its Falcon 9 rocket lifting off from Cape Canaveral in Florida. The first stage completed its fifth flight, landing safefly back at Cape Canaveral. The capsule is on its fifth flight, and successfully docked with ISS this morning.

Finally, Rocket Lab launched a “confidential commercial” payload under a contract designed to launch very fast after contract signing, its Electron rocket lifting off from one of its launchpads in New Zealand.

The leaders in the 2024 launch race:

108 SpaceX
49 China
13 Russia
12 Rocket Lab

American private enterprise now leads the rest of the world combined in successful launches 126 to 75, while SpaceX by itself still leads the entire world, including American companies, 108 to 93. Note too that with these launches the world has exceeded 200 launches in 2024, the second time this has ever been done, with the record of 213 launches set last year. This record will almost certainly be broken sometime this month.

Sunspot update: in October solar activity increased after September’s crash

3:35 pm

Time for this month’s sunspot update. As I have done every month since I started this website in 2010, I am posting NOAA’s most recent update of its monthly graph tracking the number of sunspots on the Sun’s Earth-facing hemisphere, adding some additional details to provide context.

In October, following a crash in activity in September, the Sun showed a slight increase the number of sunspots. The increase did not match the drop from the month before, but it brought the activity back up to the level seen during the summer.

Farewell to America

12:57 pm

The Liberty Bell
“Proclaim liberty throughout all the land unto all
the inhabitants thereof.” Photo credit: William Zhang

Despite my headline, this essay is not intended to be entirely pessimistic. Instead it is my effort to accept a reality that I think few people, including myself, have generally been able to process: The country we shall see after tomorrow’s election will not be the America as founded in 1776 and continued to prosper for the next quarter millennium.

The country can certainly be made great again. Elon Musk’s SpaceX proves it, time after time. The talent and creativity of free Americans is truly endless, and if Donald Trump wins it is very likely that energy will be unleashed again, in ways that no one can predict.

The country can certainly become free again. There is no law that prevents the elimination of bureaucracy and regulation, no matter how immortal government agencies appear to be. The fall of the Soviet Union in 1991 proves this. Though Russia has sadly retreated back to its top-down government-ruling ways, the country did wipe out almost all its bureaucracy in 1991, resulting in an exuberant restart that even today is nowhere near as oppressive as Soviet rule.

Should Donald Trump win, we should have every expectation that he will do the largest house-cleaning of the federal government ever. The benefits will be immeasurable, and magnificent.

What however will not change, even if Donald Trump wins resoundingly tomorrow, is the modern culture and political ethics that now exist. That modern culture is fundamentally different than the America that existed during the country’ s first 200 years, and it guarantees that America can never be the country it once was.

A 2017 supernova as spotted by Hubble

11:20 am

Before and after of galaxy with supernova
Click for original image.

Cool image time! The pictures to the right were both compiled from photos taken by the Hubble Space Telescope, with the bottom annotated to indicate the location of a 2017 supernova that was not visible in the earlier 2005 picture.

In this collage two images of the spiral galaxy NGC 1672 are compared: one showing supernova SN 2017GAX as a small green dot, and the other without. The difference between the images is that both have been created by processing multiple individual Hubble images, each taken to capture a specific wavelength of visible light, and combining them to make a full-colour image. In one of those filtered frames, taken in 2017, the fading supernova is still visible

NGC 1672 is considered a barred spiral galaxy. Located an estimated 52 million light years away, the 2017 supernovae was not the last detected within it. In 2022 a second supernovae occurred. That’s two supernovae within five years. Meanwhile the Milky Way has not seen a supernova in more than four centuries.

Australia cancels $7 billion satellite contract with Lockheed Martin

9:52 am

The Australian government today announced it has canceled a $7 billion contract with Lockheed Martin, issued only eighteen months ago, to build geosynchronous communications satellites for its military.

The project — known as JP9102 — was expected to include locally controlled and operated geostationary communications satellites, as well as multiple ground stations, but on Monday the Department of Defence confirmed it no longer met “strategic priorities”.

“With the acceleration in space technologies and evolving threats in space since the project’s commencement, defence has assessed that a single orbit GEO-based satellite communications system would not meet strategic priorities,” the statement read. “As such, defence has decided to cease its current procurement activity with Lockheed Martin Australia for a single orbit GEO-based satellite communications system.”

The project had been initiated by the previous government. The new Labor government however appears less interested in defense spending, and has been cutting related government space projects aggressively.

Polaris Spaceplanes begins test flights of its second Mira prototype

9:42 am

After losing its first Mira prototype test plane during a flight in May, the German startup Polaris Spaceplanes has now begun test flights of its replacement, dubbed Mira-2.

With this prototype the company hopes to test its aerospike engine in flight for the first time, leading to the construction of its full scale spaceplane Aurora.

This five-metre-long vehicle is equipped with jet engines for take-off and landing and one of the company’s in-house developed AS-1 aerospike engines for rocket-powered flight.

POLARIS conducted the first three test flights of the MIRA II demonstrator at the Peenemünde Airport on the coast of the Baltic Sea. Over the three flights, the vehicle accumulated a total of 20 minutes of flight time and covered more than 50 kilometres.

All three flights were unmanned, as Mira-2 is relatively small. The company will now install the aerospike engine, with the next flights testing that engine. If successful, it would be the first time ever an aerospike rocket engine has ever flown.

Three Chinese astronauts return to Earth

9:32 am

Three Chinese astronauts safely landed in Mongolia today after completing a six month mission on China’s Tiangong-3 space station.

Ye Guangfu, on his second flight, and two rookies, Li Cong and Li Guansu, lifted off on April 25, 2024 at 8:59 am EDT and docked about six-and-a-half hours later. They’ve been aboard the past six months conducting scientific experiments and performing maintenance activities including a space walk.

They landed today, November 3, at 12:24 pm EST at the Dongfeng landing site in the Inner Mongolia Autonomous Region. China is 13 hours ahead of EST, so it was a nighttime landing there at 1:34 am November 4. China’s CGTN television network provided live coverage. Descent and touchdown were captured by infrared cameras.

A new crew has taken over occupancy of Tiangong-3, and has now started its own six month mission.

Australia issues licenses for two spaceports

9:27 am

Australian commercial spaceports
Australia’s commercial spaceports. Click for original map.

The Australian government has now issued permits for two different spaceports, making possibly orbital launches at both in the near future.

First the planning minister for the province of South Australia has issued final approval allowing launches at the Southern Launch facility on Australia’s southern coast, though that approval included serious restrictions, such as no rocket launched could be taller than 30 meters. He also placed limitations on the number of launches per year, 36, the amount of noise a launch could make, and added other rules “regarding cultural heritage and native vegetation management.”

The spaceport hopes to complete its first orbital launch by the end of next year. Not surprisingly, the leftists in Green Party opposed the spaceport.

Second, the Australian Space Agency issued a launch license to Gilmour Space at its Bowen spaceport on the eastern coast of Australia, seven months late. This quote from the company’s founder is instructive:

But Mr Gilmour said when he and his brother, James Gilmour, set out to be the first to build a rocket of its kind in Australia almost a decade ago, he never imagined that getting a [launch] permit would be the most difficult part. “In my wildest dreams, I didn’t think it’d take this long,” he said. “I honestly thought the environmental approval [to launch a rocket over the Great Barrier Reef] would take the longest, and we got that well over a year ago.”

The company had originally hoped to launch early this year. It still hopes to do so before the end of 2024.

Japan launches military communications satellite

9:12 am

Japan today successfully launched a military communications satellite on the fourth launch of Mitsubishi’s new H3 rocket.

Liftoff occurred at Japan’s Tanegashima spaceport on the southern end of Japan’s island chain.

This was Japan’s fifth launch in 2024, the most launches it has accomplished in a single year since it completed six in 2018. As such the leader board in the 2024 launch race remains unchanged:

107 SpaceX
49 China
12 Russia
11 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 124 to 74, while SpaceX by itself still leads the entire world, including American companies, 107 to 91.

Rocket startup Relativity experiencing money troubles

11:55 am

According to a report from Bloomberg today and based on anonymous sources, the rocket startup Relativity is experiencing serious cash shortages that threaten its future.

Relativity Space Inc., the privately held US maker of 3D-printed rockets that once soared to a $4.2 billion valuation, is running low on cash, raising questions about the future of its launch business, people familiar with the matter said.

The company has faced challenges raising additional capital, said the people, who spoke on condition of anonymity because the matter is confidential. Relativity, which last launched a rocket in March 2023 and has plans to launch its larger Terran R in 2026, hasn’t reached a decision on a path forward.

It is hard to say whether this information is correct. However, the story also had this tidbit that I myself have heard from my own sources:

The company also announced plans to incorporate more traditional manufacturing methods with Terran R, moving away from using 3D printing.

Since from its very founding Relativity touted 3D printing as the wave of the future, claiming its decision to build its rockets entirely in that manner would produce rockets fast and cheaply. That it is no longer doing this suggests that reality was not the same as these visions, and the company discovered that it is better to look for the best way to do each thing rather than try to fit everything into the same mold.

It also appears that the company spent a lot of its capital trying to make 3D printing work, and as a result it is now short of cash.

Another model proposed for explaining flowing liquid water in the distant Martian past

2:35 pm

New model for explaining flowing water on Mars
Click for full resolution graphic.

A new model has now been proposed for explaining how liquid water could have once flowed on Mars and created the many channels and river-like features geologists see today.

This new theory posits that the carbon dioxide in the atmosphere, once thicker, fell as snow to bury water ice on the surface near the poles, where that ice then melted from pressure and heat from below to flow underground and then out into lower latitudes.

The paper, led by Planetary Science Institute Research Scientist Peter Buhler, describes how 3.6 billion years ago, carbon dioxide froze out of Mars’ atmosphere and deposited on top of a water ice sheet at the poles, insulating heat emanating from Mars’ interior and increasing the pressure on the ice. This caused roughly half of Mars’ total water inventory to melt and flow across its surface without the need for climatic warming.

The graphic to the right is figure 1 from Buhler’s paper. It shows this process in the south pole, flowing north through Argyre Basin and along various now meandering channels to eventually flow out into the northern lowland plains. In every case Buhler’s model posits the water flowed in “ice-covered rivers” or “ice-covered lakes”, the ice protecting the water so that it could flow as a liquid.

This model confirms once again my impression that the Mars planetary community is increasingly considering glaciers and ice as a major past factor in shaping the planet we see today. This model suggests liquid water under ice, but it still remains possible that ice alone could have done the job.

A somewhat typical but strange crater in Mars’ Death Valley

A somewhat typical crater in Mars' death valley
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 29, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The camera team labels the primary feature in this picture as “ridges,” but what I see is a strange crater that at first glance appears to be impact-caused, but at closer inspection might be something else entirely.

This unnamed crater is about one mile wide. It is only about fifty feet deep, but sits above the surround landscape by about 200 feet. That high position suggests strongly that this crater was not formed by an impact by is instead a caldera from some sort of volcanic activity, with the splash apron around it simply examples of past magma flows erupting from within.

The ridges inside the crater might be glacial debris, as this location is at 35 degrees south latitude, making near surface ice possible.

Boeing finally shuts down its DEI division

12:33 pm

Boeing's racist hiring goals in 2024
Boeing’s racist hiring goals in 2024

According to a report from Bloomberg news today, Boeing has now dismantled its Diversity, Equity, and Inclusion (DEI) division, with its head leaving the company.

Staff from Boeing’s DEI office will be combined with another human resources team focused on talent and employee experience, according to people familiar with the matter. Sara Liang Bowen, a Boeing vice president who led the now-defunct department, left the company on Thursday. [emphasis mine]

The highlighted phrase above tells us all we need to know. The focus under Boeing’s new CEO Kelly Ortberg will be “talent and employee experience,” not skin color or gender.

Bowen wrote the following in announcing her dismissal:

It has been the privilege of my lifetime to lead Equity, Diversity, and Inclusion at the Boeing company these past 5+ years. Our team strived every day to support the evolving brilliance and creativity of our workforce. The team achieved so much – sometimes imperfectly, never easily – and dreamed of doing much more still. [emphasis mine]

As far as I can tell, all that Bowen accomplished was to destroy the reputation of Boeing as a quality manufacturer of aerospace products. Instead, it became a place which hired people based on their race, and didn’t care if they knew the difference between a screwdriver and a forklift. The screen capture to the right comes from the company’s 2024 Boeing Sustainability & Social Impact Report [pdf], which is still online, as is the webpage of Boeing’s DEI division. Both still tout the racist quota goals of this DEI department that forced the company to consider race and gender above talent and experience in its hiring. Hopefully that ugliness will vanish soon as well.

Meanwhile, Boeing union employees on the west coast are about to vote on a third contract proposal, having rejected the previous two and going on strike since mid-September. I suspect the decision above to get rid of this poisonous DEI department will sit well with those union employees, and likely help to encourage them to approve the plan.

Scientists use Hubble and Webb to confirm there are as yet no planets forming in Vega’s accretion disk

11:16 am

Hubble and Webb images of Vega's accretion disk
Click for original image.

Using both the Hubble and Webb space telescopes, scientists have now confirmed, to their surprise, that the accretioni disk that surrounds the nearby star Vega is very smooth with almost no gaps, and thus apparently has not new exoplanets forming within it.

The two pictures to the right, cropped and reduced to post here, come from two different papers. The Hubble paper is here [pdf] while the Webb paper is here [pdf]. From the press release:

Webb sees the infrared glow from a disk of particles the size of sand swirling around the sizzling blue-white star that is 40 times brighter than our Sun. Hubble captures an outer halo of this disk, with particles no bigger than the consistency of smoke that are reflecting starlight.

The distribution of dust in the Vega debris disk is layered because the pressure of starlight pushes out the smaller grains faster than larger grains. “Different types of physics will locate different-sized particles at different locations,” said Schuyler Wolff of the University of Arizona team, lead author of the paper presenting the Hubble findings. “The fact that we’re seeing dust particle sizes sorted out can help us understand the underlying dynamics in circumstellar disks.”

The Vega disk does have a subtle gap, around 60 AU (astronomical units) from the star (twice the distance of Neptune from the Sun), but otherwise is very smooth all the way in until it is lost in the glare of the star. This shows that there are no planets down at least to Neptune-mass circulating in large orbits, as in our solar system, say the researchers.

At the moment astronomers consider the very smooth accretion disk surrounding Vega to be rare and exception to the rule, with most debris disks having gaps that suggest the presence of newly formed exoplanets within them. That Vega breaks the rule however suggests the rule might not be right in the first place.

North Korea launches test ballistic missile for the 1st time in almost a year

10:59 am

North Korea not only successfully launched on October 30, 2024 a test ballistic missile for the 1st time in almost a year, the missile set a new altitude record, reaching an altitude of 4,350 miles, more than a thousand miles higher than the country’s previous missile record.

Japanese Defense Minister Gen Nakatani told reporters the missile’s flight duration of 86 minutes and its maximum altitude of more than 7,000 kilometers (4,350 miles) exceeded corresponding data from previous North Korean missile tests.

Having a missile fly higher and for a longer duration than before means its engine thrust has improved. Given that previous ICBM tests by North Korea have already proved they can theoretically reach the U.S. mainland, the latest launch was likely related to an effort to examine whether a missile can carry a bigger warhead, experts say.

In other words, North Korea is getting very close to having an operational ICBM that can deliver a nuclear warhead anywhere on the globe. Worse, it appears this solid-fueled rocket launches from a large mobile vehicle, making it impossible to locate and destroy beforehand.

Hypersonic engine manufacturer Reaction Engines goes bankrupt

9:52 am

Reaction Engines, the British hypersonic engine company that since 2011 has been touting its Skylon spaceplane and winning a variety of development contracts to build it. has now gone bankrupt, shutting down all operations.

However, this year, the company found itself in major financial difficulties due to unexpectedly slow growth and the inability to secure an additional £150 million (US$193 million) in funding, followed by BAE Systems and Rolls-Royce being unwilling to put up bail-out capital.

As a result, as of October 31, Reaction Engines is in the hands of administrators PricewaterhouseCoopers (PwC). The company’s website forwards to PwC where there is a notice saying that further information will be released to creditors as the available assets are assessed. According to Sky News, 173 of the company’s 208 staff were made redundant.

After more than a decade of work and no apparent progress, it appears no one was willing to front the company any additional cash.

European Commission finally awards contract to build its government Starlink-type constellation

9:38 am

The European Commission yesterday finally awarded a gigantic contract to a consortium of European satellite companises to build its government-conceived and government-designed communications constellation designed to duplicate constellations already in orbit and built by Starlink and OneWeb.

The full constellation, dubbed IRIS2 and first proposed in 2022, is expected to have 290 satellites. The consortium, dubbed SpaceRISE, is led by satellite companies SES, Eutelsat, and Hispasat, and also includes Thales Alenia Space, OHB, Airbus Defence and Space, Telespazio, Deutsche Telekom, Orange, Hisdesat, and Thales SIX.

In other words, practically every major European aerospace company gets a piece of the pie.

According to a 31 October press release, the European Commission aims to have the IRIS2 service up and running by 2030. The project was initially expected to cost approximately €6 billion, of which the European Commission would provide 60%, with the rest being covered by private industry. However, recent reports have indicated that the project’s budget will likely reach as much as €10 billion.

Based on these numbers, it is going to take more than six years to launch, with each satellite costing about 3.5 million euros.

This is a very typical European government project, conceived not to fill a real need but to make sure there is a European version of something for Europe to use. It is also conceived as a way to transfer cash to as many European aerospace contractors as possible. Considering the number of companies involved and the fact that the whole constellation is government designed, expect the budget to well exceed ten billion euros before completion, and take far longer to become operational than presently planned. For example, the project was first proposed more than two years ago and only now has the contract been issued. In that time SpaceX conceived and has practically launched its entire direct-to-cell Starlink constellation of about the same number of satellites.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on August 16, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The science team labels these strange features “ring-mound landforms,” a term that has been used to describe [pdf] only vaguely similar features previously found in the Athabasca flood lava plain almost on the other side of Mars. That paper suggested that those ring mounds formed on the “thin, brittle crust of an active fluid flow” created by an explosive event. Since Athabasca is considered Mars’s most recent major flood lava event, the fluid was likely lava, which on Mars flows more quickly and thinly in the lower gravity.

Thus, in Athabasca the ring-mounds formed when a pimple of molten lava from below popped the surface.

But what about the ring mounds in the picture to the right?
