India and China complete launches

10:45 am

Two more launches today. First, India’s space agency ISRO successfully placed a joint NASA-ISRO radar satellite into orbit, its GSLV rocket lifting off from its Sriharikota spaceport on the eastern coast of India.

This was India’s first fully successful launch in 2025. On the first launch in January, the GSLV rocket performed as planned, but the satellite’s own engines failed to put it into the right orbit. Then in May the third stage of its PSLV rocket failed during launch.

Next China placed the sixth group of nine satellites for one of its mega-constellations designed to compete with Starlink, its Long March 8A rocket lifting off from its Wenchang coastal spaceport.

The leaders in the 2025 launch race:

94 SpaceX
40 China
10 Rocket Lab
9 Russia

SpaceX still leads the rest of the world in successful launches, 94 to 70.

Curiosity looks back

Curiosity looks back
Click for original image.

Cool image time! The picture to the right, reduced and enhanced to post here, was taken on July 28, 2025 by the left navigation camera on the Mars rover Curiosity. It looks to the north, down the flanks of Mount Sharp and across the floor of Gale Crater to its mountainous rim about 30 miles way, seen on the horizon.

The view is so clear because of the season, as noted in the science team’s blog post today:

We’re still in the time of year where the atmosphere at Gale is reasonably dust-free (at least, compared to later in the year), allowing us to look all the way out to and beyond the Gale crater rim. The upper slopes of Mount Sharp have also re-emerged to our east after spending months hidden behind the walls of Gediz Vallis. There’s a bit more sand and dust in this location than we’ve seen recently, so we can also see the trail left behind by the rover’s wheels as we drove to this location

The ridge in the foreground is an example of the boxwork Curiosity is presently traversing. It is now on one of those ridges, and will be moving along it in short drives as the science team studies the geology here. The rover’s tracks leading up to this position can be seen clearly.

A Webb false color image of a planetary nebula

A Webb false color image of a planetary nebula
Click for original image.

Cool image time! The picture to the right, reduced and sharpened to post here, was released today by the science team of the Webb Space Telescope, showing the planetary nebula NGC 6072 in infrared false color.

This particular image was one of two taken by Webb, and looked at the nebula in the near infrared.

[I]t’s readily apparent that this nebula is multi-polar. This means there are several different elliptical outflows jetting out either way from the center, one from 11 o’clock to 5 o’clock, another from 1 o’clock to 7 o’clock, and possibly a third from 12 o’clock to 6 o’clock. The outflows may compress material as they go, resulting in a disk seen perpendicular to it. Astronomers say this is evidence that there are likely at least two stars at the center of this scene. Specifically, a companion star is interacting with an aging star that had already begun to shed some of its outer layers of gas and dust.

The central region of the planetary nebula glows from the hot stellar core, seen as a light blue hue in near-infrared light. The dark orange material, which is made up of gas and dust, follows pockets or open areas that appear dark blue. This clumpiness could be created when dense molecular clouds formed while being shielded from hot radiation from the central star. There could also be a time element at play. Over thousands of years, inner fast winds could be ploughing through the halo cast off from the main star when it first started to lose mass.

The second image, taken in the mid-infrared, shows expanding dust shells, with some forming an encircling ring around the central nebula.

It is believed that the two stars at the center of this nebula act to churn the expanding material to form this complex shape. Imagine them functioning almost like the blades in a blender.

Next Starship moves to launchpad for static fire testing

9:16 am

SpaceX has now finished work adapting the Boca Chica launchpad for Starship and has installed the next Starship prototype there for static fire testing prior to the tenth orbital test flight expected in the next few weeks.

The pad is normally configured for Superheavy. SpaceX engineers have quickly jury-rigged it to fit Starship to it for static fire tests because the normal Massey test stand was badly damaged in an explosion during static fire tests of the previous prototype in June.

With this setup, SpaceX is going to be able to static fire a ship on Pad 1 (A). SpaceX will likely do some quick pressure and leak checks; however, no tanking tests appear to be planned. SpaceX seems confident enough in this setup that crews are aiming for a static fire on Wednesday, July 30, and a second static fire on Thursday, July 31. Both of these days have testing closures set for 7 am – 7 pm CDT.

If these go as planned and there are no issues, which, considering how makeshift this setup is, would be a massive achievement. Once its engine testing is completed, SpaceX will roll Ship 37 back to Mega Bay 2 for final work and return the pad to launch configuration; this process could take approximately two weeks.

The company will then do its standard static fire tests of Superheavy, stack Starship on top, and be ready for launch, hopefully by mid- to late August.

This Starship is one of the last two version-2 Starships being prepped for test flights. After they have flown, the company will move to version-3, which hopefully will have a better flight success record than version-2.

Thales Alenia ships the orbit insertion module for the Mars sample return mission

8:59 am

Though the entire project remains in limbo at NASA and might be cancelled, the European aerospace company Thales Alenia this week completed construction of the orbit insertion module for the Mars sample return mission that will place the orbiter — also built by European companies — in Mars orbit and will eventually bring the samples back to Earth.

On 28 July, Thales Alenia Space announced that the module had passed its test campaign with “excellent results.” According to the update, the company had packed and shipped the Orbit Insertion Module from its Turin facilities to Airbus in Stevenage a few days earlier. The delivery marks a key milestone in the development of the Mars Return Orbiter.

The broader Earth Return Orbiter project passed a key milestone in July 2024 with the completion of the Platform Critical Design Review. This review confirmed the performance, quality, and reliability of the mission’s systems. With its successful conclusion, Airbus advanced to full spacecraft development, including the integration and testing of its various components, among them the Orbit Insertion Module.

Under the project’s present very complex design, NASA is supposed to provide the ascent rocket and capsule to bring the samples to Europe’s return orbiter. At the moment it is unclear who will build this, or even if it will ever get built. Thus, Europe might be building a very expensive Mars orbiter with no clear mission.

Firefly wins new NASA lunar lander contract, worth $176.7 million

8:52 am

NASA announced yesterday that it has awarded Firefly a $176.7 million contract to use the company’s Blue Ghost lunar lander to deliver two rovers and three other science instruments to the Moon’s south pole region.

Under the new CLPS task order, Firefly is tasked with delivering end-to-end payload services to the lunar surface, with a period of performance from Tuesday to March 29, 2030. The company’s lunar lander is targeted to land at the Moon’s South Pole region in 2029.

This is Firefly’s fifth task order award and fourth lunar mission through CLPS. Firefly’s first delivery successfully landed on the Moon’s near side in March 2025 with 10 NASA payloads. The company’s second mission, targeting a launch in 2026, includes a lunar orbit drop-off of a satellite combined with a delivery to the lunar surface on the far side. Firefly’s third lunar mission will target landing in the Gruithuisen Domes on the near side of the Moon in 2028, delivering six experiments to study that enigmatic lunar volcanic terrain.

One of the rovers is being built in partnership with Canada.

Gilmour’s first launch a failure

4:55 pm

Eris rocket launch and failure
Click for video, cued to just before launch.

The first launch of the Australian rocket startup Gilmour Space’s Eris rocket ended in failure today when the rocket started drifting sideways after rising about 150 feet and then crashing near the launchpad.

The picture to the right is a screen capture from an independent live steam of the launch posted on youtube by Aussienaut, captured about 20 seconds after liftoff. The red dot indicates the location of the launchpad where the rocket took off to make clear the rocket’s sideways motion. Ten seconds after this, the rocket fell to the ground and exploded.

This launch attempt was the first ever by a private commercial Australian rocket company, so the failure itself is not surprising. It was also the first orbital test launch from a privately owned Australian spaceport. Whether the company has the resources to recover remains to be seen, but I suspect it will try again.

Starlab partners with the interior design company Journey

3:12 pm

Starlab design in 2025

for original image.

The consortium designing the commercial Starlab space station has now signed a partnership deal with the interior design company Journey for the latter to design the station’s habitable interior.

Journey brings a deep portfolio of globally recognized projects, including the Sphere in Las Vegas, the Empire State Building observatory in New York City and the Sun Princess Dome for Princess Cruises. The agency will be working closely with Hilton, one of the original strategic partners in the Starlab program, designing the Starlab hospitality and crew experience. Journey’s role adds a vital layer of design and experiential innovation, shaping a space that reflects both function and humanity.

Much of the press release is similar blather. It is good that Starlab is thinking about making the living space in its station “both a cutting-edge research platform and a welcoming, livable habitat,” but this deal doesn’t include any actual design work. Apparently nothing concrete will be done until Starlab wins the big NASA construction project — assuming it does so. Thus, I still rank Starlab low in my rankings of the four commercials stations being built or proposed, but this deal has convinced me to raise its ranking above Orbital Reef. Both have built little, but Starlab is at least making a lot of partnership deals with others, strengthening the quality of its team.

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, with Haven-1 to launch and be occupied in 2026 for an estimated 30 days total. It hopes this actual hardware and manned mission will put it in the lead to win NASA’s phase 2 contract, from which it will build its much larger mult-module Haven-2 station..
  • Axiom, being built by Axiom, has launched four tourist flights to ISS, with the fourth carrying government passengers from India, Hungary, and Poland. Though there have been rumors it has cash flow issues, development of its first module has been proceeding more or less as planned.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman, with an extensive partnership agreements with the European Space Agency and others. It recently had its station design approved by NASA, but it has built nothing. The company however has now raised $383 million in a public stock offering, which in addition to the $217.5 million provided by NASA gives it the capital to begin some construction.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Overall, Blue Origin has built almost nothing, while Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building its module for launch.

Third star destroying part of expanding shells surrounding binary Wolf-Rayet stars

3:00 pm

Apep system.
From figure 3 of the paper.

Using the Webb Space Telescope, astronomers think they can now disentangle the strange spiral shape of the expanding dust shells caused by the colliding powerful winds flowing from a binary pair of giant aging Wolf-Rayet stars, dubbed the Apep system.

Apparently, a third smaller O-type star sits in the system, and is acting to block the winds and destroy the dust within them, carving out a large cavity in the spiral shells. The image to the right, produced by the Very Large Telescope in Chile, shows the spiral dust shells shaped by the strong solar winds flowing and colliding from the binary Wolf-Rayet stars (the bright dot in the center). The O-type star can be seen just above them. The yellow lines indicate the empty cone. Without the O star computer models had predicted a very bright shell north of the binary, and its non-existence in VLT images caused these further Webb observations.

From the paper’s [pdf] conclusion:

The JWST observations of Apep reveal luminous circumstellar dust that support[s] … our finding that the O supergiant ‘northern companion’ is dynamically associated with the binary WR stars in Apep; this is the first time that dust destruction has been observed by a tertiary star in a colliding wind nebula, and marks Apep as part of a rare class of triple colliding wind binaries.

The dust produced by Wolf-Rayet stars is thought to be a major component in seeding the formation of later stars, such as our own Sun. Finding that a third star in the system can destroy that dust suggests (as always) that this process can be far more complicated that first believed.

Firefly hopes to raise more than $600 million in initial stock offering

9:03 am

The rocket startup and lunar lander company Firefly yesterday posted details about its initial public stock offering, designed to hopefully raise more than $600 million.

Firefly Aerospace, a market leading space and defense technology company, today announced that it has launched the roadshow for its proposed initial public offering of 16,200,000 shares of its common stock. In addition, Firefly intends to grant the underwriters a 30-day option to purchase an additional 2,430,000 shares of its common stock at the initial public offering price, less underwriting discounts and commissions. The initial public offering price is expected to be between $35.00 and $39.00 per share.

The company stated it would use the money “to repay outstanding borrowings under its credit agreement, pay any accrued and unpaid dividends on certain series of its preferred stock, and for general corporate purposes.”

The company has not yet announced the date when this stock offering will become available for purchase.

Chinese pseudo-company launches classified payload

8:55 am

The Chinese pseudo-company Ispace successfully placed a classified payload into orbit today, its solid-fueled Hyperbola-1 rocket lifting off from the Jiuquan spaceport in northwest China.

This was the first launch by Ispace since July 2024, following a launch failure. Not only did China’s state-run press say nothing about the payload, no information about where the rocket’s lower stages crashed inside China was provided.

The leaders in the 2025 launch race:

93 SpaceX
39 China
10 Rocket Lab
9 Russia

SpaceX still leads the rest of the world in successful launches, 93 to 68.

Wang Leehom – More I Cannot Wish You

6:01 pm

An evening pause: This song is from the Broadway production of Cole Porter’s Guys & Dolls, which unfortunately got cut from the movie. It is song by an older man, a kind of father figure in the play, wishing the best for a young woman co-worker.

This version is actually the best live performance I could find, and amazingly it is from Beijing in 2017.

Galaxies without end

8:55 am

Galaxies without end
Click for original.

Cool image time! The picture to the right, reduced and enhanced to post here, was taken by the Hubble Space Telescope as part of a monitoring program studying the two supernovae that have occurred in this galaxy previously.

Hubble has turned its attention toward NGC 1309 several times; previous Hubble images of this galaxy were released in 2006 and 2014. Much of NGC 1309’s scientific interest derives from two supernovae, SN 2002fk in 2002 and SN 2012Z in 2012. SN 2002fk was a perfect example of a Type Ia supernova, which happens when the core of a dead star (a white dwarf) explodes.

SN 2012Z, on the other hand, was a bit of a renegade. It was classified as a Type Iax supernova: while its spectrum resembled that of a Type Ia supernova, the explosion wasn’t as bright as expected. Hubble observations showed that in this case, the supernova did not destroy the white dwarf completely, leaving behind a ‘zombie star’ that shone even brighter than it did before the explosion. Hubble observations of NGC 1309 taken across several years also made this the first time the white dwarf progenitor of a supernova has been identified in images taken before the explosion.

The image however carries a far more philosophic component. Except for the star near the top (identified by the four diffraction spikes), every single dot and smudge you see in this picture is a galaxy. NGC 1309 is about 100 million light years away, but behind it along its line of sight and at much greater distances are innumerable other galaxies, so many it is impossible to count them. And each is roughly comparable in size to our own Milky Way galaxy, containing billions of stars.

The scale of the universe is simply impossible to grasp, no matter how hard we might try.

South Korea transfers its government-built Nuri rocket to private company

8:35 am

Capitalism in space: South Korea’s space agency KARI has now completed the transfer of its government-built Nuri rocket to the private South Korea company Hanwha Aerospace.

The transfer includes a total of 16,050 technical documents. While some 2 trillion won ($1.45 billion) in public funds was invested in developing the Nuri rocket, the two sides agreed on a technology transfer fee of 24 billion won, based on direct research and development costs. The agreement comes nearly two years and 10 months after Hanwha Aerospace was selected as the preferred negotiator.

Under the contract, Hanwha Aerospace has secured exclusive rights to lead Nuri production until 2032, which coincides with the government’s target for the next-generation Korean launch vehicle. [emphasis mine]

The highlighted phrase is important, as it shows that this transfer is not completely shifting space development and ownership from the government to the private sector. Hanwha is going to operate the rocket, but it does not appear to own it, nor is it clear it will be allowed to market it to others for profit. Furthermore, it is not Hanwha but KARI that will be developing the next-generation rocket, using government funds.

The dominance of the South Korean government is also reflected in the cost, as the article notes that the Nuri rocket costs “per kilogram … about 10 times that of SpaceX’s reusable Falcon 9.” Like all governments, KARI was not focused on profit in developing Nuri, so it built a rocket uncompetitive in the present launch market.

Still, this deal indicates the South Korean government’s recognition that it must foster a robust private sector aerospace industry if it truly wishes to enter the space age. This deal is thus just a first step.

Bankrupt balloon company Space Perspective bought by European company

10:15 am

The bankrupt high-altitude balloon company Space Perspective has now been purchased by the Spanish balloon startup Eos X Space.

Space Perspective “will operate with full autonomy, under U.S. leadership and corporate structure,” Eos X Space representatives said in an emailed statement on Thursday (July 24). Space Perspective’s efforts will dovetail with those of Madrid-based Eos X Space, an aerospace outfit founded in 2020 that has been working on a balloon-tourism system of its own.

Eos X is one of three Spanish balloon startups, all vying to provide high altitude flights to tourists, with the other two companies being Zero-2 and Halo. All three have been in a long legal fight, with the latter two indicted in 2023 over the theft of Eos X’s balloon concept. In an earlier legal action, Zero-2 claimed its concept was stolen by Eos X.

None, including Space Perspective, has as yet actually flown any tourists.

Another two launches by SpaceX and China

10:01 am

There were two more launches last night and today. First, SpaceX put another 24 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its 19th flight, landing on a drone ship in the Pacific.

Next, China today successfully launched another five satellites in its planned Guiwang (“king”) internet constellation of 13,000 satellites, its Long March 6 rocket lifting off from its Taiyuan spaceport in northern China. No word on where the rocket’s lower stages crashed inside China.

This launch brought the total number of operational satellites in orbit for this constellation to 39, all launched since December 2024. At this pace it will take many years for China to complete this constellation, though it likely can begin selling the service in China with an incomplete constellation. Its international licence requires it to launch 10% by 2029 and 50% by 2032.

The leaders in the 2025 launch race:

93 SpaceX
38 China
10 Rocket Lab
9 Russia

SpaceX now leads the rest of the world in successful launches, 93 to 67.

Texas Space Commission hands $5 million to proposed spaceport in the middle of Texas

12:21 pm

US and Mexico
Click for source.

In what can only be seen by anyone with any objectivity as a political payoff that has no chance of ever producing anything worthwhile, the Texas Space Commission (TSC) has given the Midland International Air and Space Port a $5 million grant to develop its proposed spaceport for vertical rockets in the middle of west Texas.

The spaceport is one of three facilities — along with ILC Aerospace in Houston and SylLab Systems in Plano — that received grant funding as part of the Space Exploration and Aeronautics Research Fund (SEARF). The SEARF provides funding to eligible companies, including government entities that the TSC is partnered with, to fund such purposes as technology development, research, workforce training, curation of materials and development of infrastructure. In its history, the SEARF fund has provided $126 million worth of grant money to 22 different projects.

…Although requested and managed by the city of Midland, the vertical launch site will be in Balmorhea in Reeves County, around the same site as the International Rocket Engineering Competition earlier this summer. The area can currently support suborbital rocket launches, but the vertical launch site is expected to support orbital flight, which will complement their horizontal launch system and high speed corridor for hypersonic flight.

The map to the right shows the location of Midland and Balmorhea. As you can see, this site makes no sense for vertical rocket launches, unless every rocket launched from the site is completely reusable. Even then, it faces major political hurdles to get permission to fly rockets over all the neighboring communities and states. The FAA would certainly have doubts.

In other words, this $5 million grant is a nice pay-off from one government agency to another, with its only purpose to spread some graft around.

That the Hearst-owned Midland Reporter-Telegram news article at the link recognizes none of this, and simply and naively spouts the propaganda put forth by government officials, once again illustrates the bankruptcy of our so-called “mainstream” press.

One of NASA’s two Tracers satellites just launched has an issue

10:17 am

During the commissioning phase shortly after their launch earlier this week, one of NASA’s two Tracers satellites designed to study the solar wind and its interaction with the Earth’s magnetic field has had an as yet unnamed issue.

During the commissioning process, the team made routine adjustments to the power subsystem on both vehicles. While the adjustments achieved the desired results on one satellite, the other satellite requires further investigation by the team. Commissioning operations are temporarily paused while the team analyzes the situation and determines the appropriate response.

Though the press release provides no other information, it appears the satellite is having a problem producing the power expected.

NASA’s work force is shrinking by about 4,000

10:11 am

The number of NASA employees that have accepted the Trump offer to leave has now grown to more than 4,000 people, reducing the entire workforce from 18,000 to 14,000.

Nearly 4,000 employees, or more than 20% of NASA’s workforce, have applied to leave the agency, NASA confirmed to CBS News Friday. About 3,870 employees have applied to depart NASA over two rounds through the Trump administration’s deferred resignation program, NASA disclosed. The deadline for applications to the program is midnight Friday.

With those deferred resignations, NASA’s civil servant workforce would shrink from about 18,000 to 14,000 personnel. This figure also includes about 500 employees who were lost through normal attrition, the agency said.

It is certain that while Trump is office these workers will not be replaced. While most of the press and pro-government activists will claim this is terrible news, it is actually the best thing that can happen. Since NASA is now trying to use the capitalism model across the board, it doesn’t need that many employees. It is hiring the private sector to do most of its work. It doesn’t take that many people to review and issue a contract.

So, even if Congress rejects Trump’s proposed 24% cut to NASA’s 2026 budget and funds it entirely at the same levels as in 2025, the money will be more effectively used.

Europe and SpaceX complete two launches late yesterday

10:01 am

Both Europe and SpaceX successfully completed launches in the early morning hours today.

First Arianespace, the European Space Agency’s (ESA) commercial arm, used Avio’s Vega-C rocket lifting off from French Guiana to put five satellites into orbit, including four high resolution Earth observation satellites and one climate satellite. This was only the third launch for Arianespace in 2025, two of which were of the Vega-C.

Next, SpaceX placed 28 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral. The first stage completed its 22nd flight, landing on a drone ship in the Atlantic.

The leaders in the 2025 launch race:

92 SpaceX
37 China

American Battlefield Trust – Famous Civil War Photos in 360°

6:01 pm

An evening pause: I just finished reading a book of letters written by a soldier who participated in the battle of Antietam, just south of Burnside Bridge. The irony was that Burnside spent more than a day and multiple attempts to capture the bridge, when in fact his troops could have simply walked across the creek at any point, never getting their legs wet above the knee. The soldier was Captain Wolcott Pascal Marsh, and his regiment actually forded the creek further south and advanced farther than almost anyone else in Burnside’s battalion. The book: Letters to a Civil War Bride.

Like all the Civil War battle fields, Antietam is definitely worth visiting.

Mars and its two moons seen in the infrared by Europa Clipper

10:37 am

Mars and its two moons
Click for original.

Cool image time! The infrared image to the right, cropped, reduced, and enhanced to post here, was taken by Europa Clipper on February 28, 2025 just before it flew past Mars on its way to Jupiter.

Deimos is in the upper left corner, while Phobos is close to Mars.

When the image was taken by the mission’s Europa Thermal Emission Imaging System (E-THEMIS), the spacecraft was about 560,000 miles (900,000 kilometers) from the Red Planet. The image is composed of 200 individual frames, part of a continuous scan of 1,100 frames taken roughly a second apart over a period of 20 minutes. Scientists are using the tiny, point-like images of the moons to check the camera’s focus.

As this is an infrared image (measuring heat), it shows Mars’ northern polar cap as the dark oval at the top of the planet. The bright (and thus warmer) oval to the lower left is the shield volcano Elysium Mons.

This data suggests Europa Clipper’s thermal instrument is working as intended, which is essential for observing the ice content (if any) on Europa once it enters Jupiter orbit in 2030.

The journal Science retracts 15-year-old paper that proposed arsenic as basic element of life

10:15 am

The death of science: Though numerous later research had rejected the conclusions of a 2010 research paper that had suggested a bacteria found at Mono Lake in Californa was using arsenic instead of phosphorus in its DNA, the journal Science that published that paper has now retracted it.

In a blog post accompanying this week’s retraction notice, Science’s current Editor-in-Chief Holden Thorp and Valda Vinson, executive editor of the Science family of journals, emphasize there is no suggestion of foul play in the GFAJ-1 paper. Instead, pointing to subsequent commentary and research that suggest some of the paper’s findings stem from contamination, not arsenic use by bacteria, they write: “Science believes that the key conclusion of the paper is based on flawed data.”

Speaking with Science’s News team, which operates independently from its research arm, study co-author and Arizona State University geochemist Ariel Anbar says the team disputes that assessment and has already addressed the referenced criticisms. “We stand by the data,” he adds.

Anbar added this in this report at Nature:

By contrast, one of the paper’s authors, Ariel Anbar, a geochemist at Arizona State University in Tempe, says that there are no mistakes in the paper’s data. He says that the data could be interpreted in a number of ways, but “you don’t retract because of a dispute about data interpretation”. If that’s the standard you were to apply, he says, “you’d have to retract half the literature”.

This action underlines the decline in open-mindedness in the academic field. It did not suffice to simply demonstrate in later papers that the paper’s conclusions were questionable. It was necessary to cancel it entirely, to airbrush it from history.

Dassault lobbies ESA to fund its Vortex reusable mini-shuttle

9:51 am

Dassault's proposed Vortex mini-shuttle
Dassault’s proposed Vortex mini-shuttle. Click for original.

The French aerospace company Dassault is now lobbying the European Space Agency to help finance its proposed Vortex reusable mini-shuttle, comparable in concept to Sierra Space’s Dream Chaser spacecraft.

The company had first announced this project in June.

While the June announcement included few details, a 25 June hearing of the French National Assembly’s Committee on National Defence and the Armed Forces revealed that the mission is expected to be launched in 2027 aboard a Rocket Lab Electron rocket. The hearing also disclosed that the demonstration mission has a total budget of €70 million, with Dassault providing more than half of the funding and the remainder coming from the French government.

Dassault is now attempting to get more funding from ESA. In June it had signed an agreement with ESA to partner on building a demonstrator, but it was not clear that agreement included funding. It certainly did not include funding for the full scale operational mini-shuttle.

Overall, the structure of funding and the design of the project is good, and demonstrates again Europe’s sharp shift to the capitalism model in the past two years. Dassault will design, build, and (most importantly) own the shuttle, allowing it to market it to many customers. It is also committing a significant amount of its own funds to the project. The funding from France and possibly ESA appears mostly that of a customer buying the services of this product from the company.
