  • 40 members of Congress send letter to NASA, complaining about cuts to Mars Sample Return mission
  • It’s all a game. NASA makes the cuts to generate protests. Congress screams and protests. The two get together and fund everything, then claiming they saved the world. In this game however no one ever asks: “Is the project as designed worth the money? Can this be done a better way?” To ask such questions would suggest maybe the money shouldn’t be spent, and that concept is wholly alien to these swamp players.

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

Sunspot update: The Sun in January acted like solar maximum is here

In my monthly sunspot update at the start of January, I asked in the headline “Are we now in the next solar maximum?”

The Sun’s sunspot activity in January since then has apparently answered that question. NOAA this week posted its monthly update of its graph showing solar sunspot activity on the Sun’s Earth-facing hemisphere, and as I do every month since 2011, I have posted that graph below, with annotations to provide a larger context.

Collins Aerospace tests its new spacesuit on the Zero Gravity airplane

On January 30, 2024 Collins Aerospace, one of two companies that NASA has contracted to design and build new spacesuits for its future missions, successfully tested its new spacesuit on the Zero Gravity airplane, where it was able to have a person use the suit in short but weightless conditions.

Collins is designing its suit in collaboration with ILC Dover and Oceaneering. Former NASA astronauts, John “Danny” Olivas and Dan Burbank, each donned the suit and performed a series of test objectives while onboard a Zero Gravity plane that’s able to perform parabolic maneuvers to simulate microgravity for short bursts. They were surrounded by several support personnel who were gathering data about the suit performance.

In total, they performed 40 parabolas during the flight. Collins said the primary goals included “evaluation of the suit’s pressure garment system fit and functionality, use of International Space Station tools and interfaces, and reviewed performance of the new Extravehicular Mobility Unit, or EMU, against the current design.”

The two spacesuit contracts (the second is with Axiom) are costing NASA about $335 million total to get the suits designed, built, and certified for use in spacewalks and ground operations on the Moon. Both companies appear on schedule to deliver those suits in less than three years.

Previously, NASA had tried to build new spacesuits on its own, and had spent a billion dollars over fourteen years while building nothing. The contrast in this story between the government and private enterprise should be clarifying to everyone.

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 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.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

One last engineering test planned for Ingenuity

Engineers plan to do one last engineering test with Ingenuity, slowly rotate its propellers while collecting imagery, likely from both the helicopter and Perseverance.

Teddy Tzanetos, Ingenuity Project Manager, said that NASA and JPL still aren’t sure what caused the damage to Ingenuity’s blades; it remains unclear whether the helicopter’s power dipped during landing, causing unwanted ground contact, or if it accidentally struck the ground to cause a “brownout.”

Tzanetos added that NASA and the Jet Propulsion Laboratory (JPL) will slowly rotate the helicopter’s blades and “wiggle” them, or adjust their angle, while collecting video in order to allow the team to determine the extent of Ingenuity’s damage. However, Tzanetos said that no matter what such imaging will show, the dual-rotor drone has flown its last flight and will soon end its mission.

This test will likely not occur until Perseverance gets into a position where it can film the test also. The helicopter’s cameras look downward, so all it will be able to photograph is the shadow of those blades as they move. Perseverance can look directly at it, and if it gets into a position slightly higher than Ingenuity it can get a good viewing angle down at the blades.

At the moment the rover is about a thousand feet to the east, though steadily working its way towards it.

Japan’s lunar lander shuts down for long lunar night

SLIM's last image
Click for original image.

After two days of post landing operations, engineers for the Japanese lunar lander SLIM have shut it down now as the sun has set at its landing site on the Moon and its solar panel can no longer charge its batteries.

The picture to the right, reduced to post here, was the last image sent back by SLIM before shut down. It looks to the southeast across the width of 885-foot-wide Shioli Crater, the opposite rim the bright ridge in the upper right about a thousand feet away.

The engineers shut the spacecraft down prior to sunset in order to increase the chances that it will survive that very long harsh lunar night and reactivate when the Sun rises in two weeks. They recognized that the odds of this occurring are slim (no pun intended), because the lander was not designed to withstand the night’s cold temperatures, and more important, the solar panel will not get recharged until late in the lunar day, an additional week-plus past sunrise. That long period of inactivity will likely kill it.

No matter. The spacecraft’s main goal was to prove the ability of its landing system to land softly within a small target zone. It did so, even if it had an engine issue that caused it to land upside down. This new engineering will make it possible to send unmanned and manned landers to places on other planets that previously were impossible.

Texas state court rules in favor of activist lawsuit against SpaceX

The activists who sued SpaceX and local authorities, claiming the beach closures required during tests and launches at Boca Chica violate the Texas constitution, have had their lawsuit reinstated by a higher state court after a lower court had dismissed it.

Texas’ 13th district court of appeals ruled in favor of SaveRGV, the Sierra Club and the Carrizo/Comecrudo Nation of Texas in suits alleging that a 2013 state law allowing beach closures for space flight activities goes against the Open Beaches Amendment to the Texas Constitution.

In July 2022, Cameron County’s 445th District Court dismissed the coalition’s lawsuit, saying the organizations lacked standing in their complaint against Texas Land Commissioner Dr. Dawn Buckingham, the Texas Land Office, Cameron County and Texas Attorney General Ken Paxton.

The appeals court reversed that decision Thursday, allowing the lawsuit to proceed.

The lawsuit still must be litigated, so these activists have not yet won their case. However, this decision might prevent further beach closures while the case plays out in the courts, which would essentially shut down any further tests or launches at Boca Chica. If so, it will not matter if the FAA finally finishes its paperwork and approves a third test launch of Starship/Superheavy later this month. The launch will not be possible.

A soft but dim spiral

A soft but dim spiral
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken by the Hubble Space Telescope as part of a survey of nearby galaxies in which supernovae had previously been detected.

This softly luminous galaxy — lying in the constellation Hercules, about 110 million light-years from Earth — seems outshone by the sparkling foreground stars that surround it. The type II supernova which took place in this galaxy in 2019, while no longer visible in this image, definitely outshone the galaxy at the time!

What amazes me about this somewhat dim spiral galaxy is its beautiful structure, its two spiral arms coiling outward in perfect symmetry. And yet, we are looking at a object that is almost entirely empty space, hundreds of thousands of light years across. Somehow the almost infinitesimal force of gravity at those distances is still able to shape the arms, and the spirals.

Another exoplanet found in habitable zone

Astronomers using both space- and ground-based telescopes have confirmed the existence of another rocky exoplanet inside the habitable zone of its star.

The star is a red dwarf 137 light years away. The exoplanet, dubbed TOI-175 b, is estimated to be larger than Earth, with a diameter 1.5 times that of our home planet. It orbits its star every nineteen days. Even more intriguing, the data suggests this star has a second exoplanet even better positioned in the habitable zone that would be the smallest habitable-zone exoplanet so far found, about the size of Earth.

The second planet however is not yet confirmed.

This discovery is no longer very unique. In the past few years astronomers have discovered a plethora of Earth-sized exoplanets, many in the habitable zone.

Japan and India team up for unmanned lunar lander mission

Japan and India are now partnering to put a lander/rover on the Moon in 2025, dubbed LUPEX.

Set tentatively for 2025, LUPEX will be launched on JAXA’s H3 launcher, with a 350-kg rover developed by the Japanese agency. ISRO is developing the lander. The instruments will be on the lander and the rover. Initial feasibility studies and the lander’s configuration have been completed. The rover will sample the soil with a driller and the samples will be analysed using equipment on the rover,

Unlike the previously successful lunar landers from both countries (India’s Chandrayaan-3 and Japan’s SLIM), LUPEX is being designed to survive the 14-day-long lunar night, with a mission that is aiming to last three to six months.

Update on Jared Isaacman’s upcoming Polaris Dawn manned mission

Link here. Bottom line is that they still hope to launch on a five day orbital mission in SpaceX’s Resilience Dragon capsule later this year, during which they will do the first privately funded non-government spacewalk.

Developing new spacworthy spacesuits remains the biggest task before the mission can fly.

In a series of social media updates on Friday and Saturday, Isaacman answered some questions from the public about the progression of the suit development and the mission overall. He stated that over the past week, they “spent a lot of time pressurized in the EVA suits working contingencies.”

Isaacman clarified as well that, unlike missions to the International Space Station chartered by either NASA or Axiom Space, the crew members of the Polaris Dawn mission won’t launch and land while wearing IVA suits. He said because they are limited with space on this flight, they will only have their EVA suits.

No launch date has yet been set.

Voyager signs SpaceX’s Starship to launch its Starlab space station

Voyager Space, one of three commercial space stations being built in partnership with NASA, has awarded SpaceX the launch contract for putting its Starlab space station into orbit, using that company’s Superheavy/Starship rocket.

The companies did not disclose terms of the agreement or a projected launch date, although a spokesperson for Starlab Space said the company was confident that Starlab would be launched before the decommissioning of the International Space Station, currently scheduled for 2030.

Voyager is building Starlab in a joint partnership with Airbus and Northrop Grumman. The design is relatively simple though large (one main module and a service module), which makes Starship an excellent method for getting it into orbit.

SpaceX now has deals to launch two different space stations using Starship. The second is with the private company Vast, which is building its station completely independent from NASA. Starship also has won launch contracts from two different private citizens, as well as NASA.

It appears that Musk’s instincts were right on the money when he decided to build this rocket, even though when he proposed it there did not seem to be any customers for it.

Have these Martian dunes changed in sixteen years?

Comparing two MRO images taken 16 years apart
Click here and here for the original images.

Overview map

Cool image time! The two pictures above, both rotated, cropped, reduced, and enhanced to match and to post here, were taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) sixteen years apart. The first, on the left, was taken on February 23, 2007, while the second, on the right, was taken on November 1, 2023.

What drew me to both images was the label for the second: “Dune Change in Arabia Region Crater.” To find out if this image had revealed any changes in the dunes I went back and found the earliest MRO picture of this location, and sized and enhanced the dunes in both to match.

Do you see any changes? I don’t. However, that really means nothing. These are not the highest resolution versions that MRO obtains, and a very careful comparison of those best images might detect more subtle changes than our eyes can perceive in the versions above. Also, there might be brightness changes that require careful software analysis.

The white dot on the overview map to the right marks the location, in Arabia Terra, the largest transition region on Mars between the northern lowland plains and the southern cratered highlands. The inset shows the half filled crater in which these dunes sit. The grayed area on the floor of the crater marks the entire dune field, extending eastward to the crater rim from this one spot, indicated by the black dot.

It is likely that the dust is blown into this crater and gets trapped there. Whether the dunes move or change is not clear, though if they do the changes are small, even after almost two decades. Instead, the two pictures suggest these dunes have hardened into a form of sandstone, that can be eroded over time by the wind, but only very very slowly.

Shoddy Harvard — home of plagiarism and bigotry — loses another big donor

Harvard: where you get can get a shoddy education centered on hate and bigotry
Harvard: where you can spend a lot of money
getting a shoddy education teaching hate and bigotry

One of Harvard’s biggest donors, Ken Griffin, has announced that he is pausing all further donations to the university due to its now obviously shoddy educational standards combined with its advocacy of racial quotas under its Diversity, Equity, and Inclusion program.

Griffin announced his decision to stop donating to Harvard during a keynote talk at a conference hosted by the Managed Funds Association in Miami. Griffin, however, left open the possibility that the University could win back his support. “I’d like that to change and I have made that clear to members of the corporate board,” he said. “But until Harvard makes it very clear that they’re going to resume their role as educating young American men and women to be leaders, to be problem solvers, to take on difficult issues, I’m not interested in supporting the institution.”

He added that Harvard students were “whiny snowflakes” caught in a misguided ideology of oppressor and oppressed during his remarks.

Griffin also stated that his companies will hire no students who signed a group letter that expressed support for Hamas’ rape, torture, and massacre of more than 1,400 Israelis on October 7, 2023.

Griffin has donated more than half a billion to Harvard in recent years, including a $300 million donation to Harvard’s Faculty of Arts and Sciences last year.

He is also not the first billionaire to announce a boycott of Harvard. In November Bill Ackman, a billionaire hedge fund manager and Harvard alumni, released a long letter condemning the university’s former president Claudine Gay for allowing anti-Semitism to fester at the school. Like Griffin, he is apparently withholding further donations while refusing to hire students. Ackman has since repeatedly harangued Harvard in public for its refusal to take any serious reform actions.

Then in December billionaire Leonard Blavatnik stopped his own donations, also because he was appalled by the uinversity’s willingness to allow anti-Semitism to run rampant on campus.

These three men combined had previously donated almost a billion dollars total to the university. One would think their boycott would carry profound weight, and force some immediate changes at Harvard.

Scientists: No obvious ice in the permanently-shadowed interior of Shackleton Crater

Shadowcam-LRO mosaic
Click for original image.

Using the low-light image produced by the American Shadowcam instrument on South Korea’s lunar orbiter Danuri, scientists now belief that there are no thick obvious deposits of water ice in in the permanently-shadowed interior of Shackleton Crater at the Moon’s south pole.

The image to the right combines pictures taken by Lunar Reconnaissance Orbiter (LRO) of the region around Shackleton with pictures produced by Shadowcam of its permanently-shadowed interior. From their paper’s conclusion:

The trailing (right) side of Shackleton’s interior is warmer owing to the secondary illumination asymmetry and floor topography. Illumination at the floor of Shackleton is patchy and possibly indicates a similar patchy (50 m scale) temperature distribution, which could mean a spatially irregular concentration of cold-trapped volatiles at the subsurface or mixed with regolith.

According to our Shackleton crater interior mapping from ShadowCam images, there is no observed evidence of thick ice deposits or surface ice that could be easily recognized by any relative brightness features observed in multiple illumination geometries. However, this analysis did not include the estimation of reflectance, nor did it involve reviewing all of the images of Shackleton in this preliminary study. Our hypothesis, in the context of water frost detections in Shackleton, is that if ice or frost is present in Shackleton’s interior, then the concentrations are either below the threshold that results in an observable signature in ShadowCam images, or might be mixed with the regolith at the detected areas. At other places where surface temperatures are below 110K, water frost could be hidden in subsurface layers.

The paper’s main purpose was to identify the dim lighting sources within the crater, all of which come from light bouncing off other surfaces. In the process the scientists obtained a better understanding of the surface itself.

Pentagon in discussions with SpaceX about buying a Starship outright for military missions

The Pentagon is negotiating with SpaceX the idea that in certain cases where it deems it legally necessary it will buy outright full ownership of a SpaceX Starship/Superheavy launch rocket in order to fly some military missions.

The idea is similar to how the Air Force moves cargo. At times, the service contracts with private carriers to deliver cargo, but for certain critical missions it uses service “gray tail” aircraft. In this hypothetical case, the military could take a Starship off the line for a specific mission and return it to SpaceX after it is complete.

I suspect such situations involve very risky wartime missions that carry liabilities that a private company cannot accept. The military takes over ownership, relieving the company of risk, and then returns ownership afterward. Such a plan requires the company to agree to it, and the military to pay extra for these temporary rights. According to the article at the link, SpaceX is presently exploring its options.

That the Pentagon is discussing this with SpaceX at all tells us that it sees Starship/Superheavy as having a lot of value. It wants to buy its services, one way or the other.

Tank explosion in Shanghai injured three

The supposed test-to-tank failure of a rocket tank being tested by the Chinese pseudo-company Landspace on January 29, 2024 apparently injured three workers, though officials also claimed everything worked as planned.

Three workers were injured and nearby residents reported that “a huge boom” shook their windows during testing of a LandSpace rocket fuel tank in Shanghai on Monday evening. The Chinese start-up – which last year beat its rivals, including US-based SpaceX, to launch Zhuque-2, the world’s first methane-fuelled rocket, into orbit – said there were no abnormalities during the test.

A LandSpace representative told local media on Tuesday that the test “left some glass damaged and three production personnel with minor scratches”. The company and the district government said no explosion occurred.

This explosion was reported on X by nearby residents earlier this week (see the quick links here and here), with no confirmation from the pseudo-company. Even now it is being very coy about what it is telling us. An anonymous source at the link says the test filled the tank with nitrogen, and was intended “to establish the tank’s limits.”

No one however should have gotten injured during such a test, if everything took place as planned.

Private company in India aims to build its own manned capsule and astronaut training facility

A private company in India, Astroborne Aerospace, is now developing its own commercial manned capsule as well as a commercial astronaut training facility, targeting as customers Earth-based tourists as well as those hoping to fly in space.

The capsule, dubbed Airawat, will seat six, and will be designed for suborbital flights, similar to Blue Origin’s New Shepard capsule. The training facility will be on a four-acre site the company is presently negotiating either a lease or purchase from the local government.

The company says it has obtained investment capital, but also says that money will arrive next month.

Whether this deal is real or not is actually irrelevant. Its existence illustrates the underlying enthusiasm in India for private commercial space, now that the Modi government has ended the monopoly on all space activities by its space agency ISRO.

China’s Chang’e-7 lunar mission will target the rim of Shackleton Crater

The Moon's south pole, with landers

China’s Chang’e-7 lunar mission, which will include an orbiter, lander, rover, and “mini-flying” probe, will land in 2026 on the rim of Shackleton Crater, one of the same candidate landing zones for NASA’s manned Artemis program.

The map to the right shows the lander’s approximate landing site, on the illuminated rim of thirteen-mile-wide Shackleton Crater at the Moon’s south pole. The candidate landing zone for NASA is also on this rim, but the location might not be precisely the same. From the abstract of the published paper [pdf] outlining the project’s science goals:

The lander will land on Shackleton crater’s illuminated rim near the lunar south pole, along with the rover and mini-flying probe. The relay satellite (named Queqiao-2) will be launched in February 2024 as an independent mission to support relay communication for ongoing scientific exploration of Chang’E-4 (CE-4), the upcoming Chang’E-6 (CE-6) in 2024, and subsequent lunar missions.

Though the abstract states the target is Shackleton’s rim, the paper is less specific, showing a map with a much wider “candidate landing region”. It is unclear if China as yet has the ability to land with the pinpoint accuracy necessary to hit the rim as stated. The paper is also devoid of any technical details about the lander, rover, or its mini-flyer. It lists the science instruments and their science goals, but describes nothing more specific. For example, will the flyer bounce or use small rockets to lift off? Or will it simply be released prior to landing with no capability of taking off again?

The big story here is the race to get to Shackleton first. NASA presently hopes its first Artemis manned mission to land on the Moon, Artemis-3, will arrive in September 2026, with its stated goal landing at or near the south pole. That schedule is certainly tentative, based on NASA’s recent track record. China is now targeting that same year, but its recent track record for its lunar program has been far more reliable.

The Outer Space Treaty forbids both countries from claiming any territory, but possession is always nine-tenths of reality. Expect China to touch down first, and hold what it touches.

Rocket Lab launches four commercial satellites

Electron 1st stage floating in the water

Rocket Lab today successuflly launched four satellites as part of a commercial constellation designed to track all objects in orbit, its Electron rocket lifting off from one of its two New Zealand launchpads.

The company also successfully recovered the first stage using a parachute system to slow it down for a soft splashdown in the Pacific where a ship picked it up. The image to the right is a screen capture shortly after the recovery ship reached the stage, which can be seen floating in the water on the left. As of posting the ship was in the process of pulling the stage from the water. Once completed, the stage will be returned to Rocket Lab’s rocket factory for refurbishment and tests to see if it can fly again.

The 2024 launch race:

10 SpaceX
6 China
2 Iran
1 India
1 ULA
1 Japan
1 Rocket Lab

Today’s blacklisted American: U.S. Court rules against coach fired for simply stating a fact in a casual conversation

Vermont: Where you are only allowed to say things that support the queer agenda
Vermont: Where the only speech allowed must
support the queer agenda

If you are depending on the federal courts to defend your fundamental rights, as outlined very bluntly in the Bill of Rights, you are being very naive. On December 28, 2024 the U.S. Court of Appeals for the 2nd Circuit ruled against David Bloch, who had been fired in February 2023 without due process as the snowboarding coach at Woodstock Union High School in Vermont — a team that he had founded in 2011 — because he had simply mentioned in a casual and very civil conversation with two of his students that men and women are genetically different.

He was fired the next day, even though no investigation into the incident had been done, and no one involved in the conversation had complained. School officials made it clear that Bloch was being fired for daring to have an opinion they did not like.

The notice accused Bloch of violating Windsor Central Supervisory Union Board’s Harassment, Hazing, and Bullying policy and the Vermont Principals’ Association related policy for “ma[king] reference to [a] student in a manner that questioned the legitimacy and appropriateness of the student competing on the girls’ team to members of the WUHS snowboard team”—all outside the student’s presence.

A plateau of friable rock on Mars

A plateau of friable rock 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 September 13, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this “Friable Outcrops in Aeolis Dorsa.” What we are looking at is the northeasternmost tip of a 30-mile long plateau that marks the northern edge of Mars southern cratered highlands. For most of its length the top of that plateau is relatively smooth, broken by some vague surface features and a few scattered craters (suggesting it is relatively young). However, as you approach the plateau’s edges and especially that northeastern tip the surface begins to break up into the rough terrain shown to the right. It appears that the prevailing winds from the north are scouring the soft topsoil here and causing it to wear away, leaving behind those innumerable small ridges, almost all of which are oriented from north-to-south.

But why is the topsoil here soft and so easily scoured?

Spain awards rocket startup PLD $43.8 million grant

Capitalism in space: The Spanish rocket startup PLD has won a $43.8 million grant from the Spanish government to develop its Miura-5 orbital launch rocket.

The company won the funding after completing the preliminary design review (PDR) its Miura 5 small launch vehicle, a review that was then examined by an independent committee. The award is technically a loan, which will be paid off over 10 years once Miura 5 begins commercial operations, currently scheduled for 2026.

The rocket will compete directly with Rocket Lab’s Electron rocket, with a bigger payload capacity. PLD also plans to recover and reuse its first stages after splashdown in the ocean, as Rocket Lab is now attempting to do with Electron.

The significance of this deal is multifold. It shows us that Spain is now a player in space, with its own rocket company, though still only a startup. It also provides further evidence that the nations of Europe are beginning to go their own way in space, rather than rely on their partnership in the European Space Agency and its rocket division, Arianespace. Arianespace has failed to do the job, so Spain like Germany is now looking to the private sector to get its satellite payloads in orbit.

Finally and most important, this deal illustrates the shift in Europe from being the designer and owner of rockets to being a mere customer. Rather than depend on a governnment-built and owned Arianespace rocket, Spain is buying the service from a private company, PLD. That company owns it entirely and can sell its services to others as well.

This trend away from government-owned rockets bodes well for the future of space exploration in Europe. It will produce a vibrant competitive industry with many different companies coming up with different ideas that will increase innovation while reducing cost.

It also signals the coming death of Arianespace, ESA’s commercial division which despite dominating the commercial launch market for almost two decades, was never able to make a profit ever. Instead, it produced rockets that were too expensive and required subsidies on a yearly basis. The nations of Europe are no longer willing to tolerate that bad performance, and have basically told Arianespace it either must compete with these new private companies, or die. I expect it to die. If it does survive, it will only do so if it changes radically.
