An evening pause: Hat tip Wayne DeVette, who notes, “The band’s name comes from a photo of W.C. Fields in Kenneth Anger’s book Hollywood Babylon, which bore the caption ‘W.C. Fields with gin blossoms’, referring to the actor’s telangiectasia-spotted face and rhinophymic nose by the slang term for the skin condition known as rosacea.”
Only a few hours after it scrubbed the launch of its Endeavour capsule carrying four astronauts to ISS because of weather at Kennedy in Florida, SpaceX proceeded to successfully launch 19 more Starlink satellites, its Falcon 9 rocket lifting off from Vandenberg in California.
The relatively low number of Starlink satellites on this launch appears related to the higher orbit in which they were placed. The first stage completed its 27th flight, landing on a drone ship in the Pacific. SpaceX now has four boosters that have flown more than 25 times, respectively 29, 27, 26, and 26.
The leaders in the 2025 launch race:

SpaceX nowl leads the rest of the world in successful launches, 95 to 71. Meanwhile, the manned Endeavour launch has now been rescheduled for tomorrow morning.

The uncertainty of science: Using new data from the Webb Space Telescope, scientists now conclude that the identification on an exoplanet in April 2025 of the molecules dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS) — both of which on Earth are only associated with the presence of life — is now uncertain and that these molecules likely aren’t there.
The new work uses [Webb] data to better qualify what is going on. The work confirms the presence of an ocean on this peculiar exoplanet, although it can’t confirm if there is a thick or thin atmosphere. They couldn’t find water vapor in the atmosphere, suggesting that there is an efficient cold trap, keeping evaporation to a minimum on this temperate sub-Neptune world.
Those potential biosignatures were all below the threshold for an undeniable detection, and their model suggests that a possible presence of DMS could be explained by sources unrelated to life. They advise considering more and different molecules to use as biosignatures. Astronomers are studying worlds that are very different from our own, and the chemical signatures that seem obvious here on Earth might not fit well with those exoplanets.
In other words, they simply don’t have enough data to know, one way or the other. No surprise, The science of studying exoplanets is in its infancy, and right now can only tease out the smallest of details based on our limited technology and the distances involved.
You can read the new paper here [pdf]. It notes further that using these molecules as a sign of life is also a mistake, as they can be created in other ways having nothing to do with biology.
Artemis, a program based on fantasy
Increasingly it appears everyone in Congress, the White House, and NASA, as well as our bankrupt mainstream press, has become utterly divorced from reality in talking about NASA’s Artemis lunar program. The claims are always absurd and never deal with the hard facts on the ground. Instead, it is always “Americans are piorneers! We are great at building things! We are going to beat China to the Moon!”
An interview of interim NASA administration (and Transportation secretary) Sean Duffy yesterday on the Sean Hannity Show made all these delusions very clear. First Hannity introduced Duffy by stating with bald-faced ignorance that “NASA has a brand-new program. It is called Artemis that aims to get astronauts back on the Moon in the next couple of years.”
I emphasize “brand-new” because anyone who has done even two seconds of research on the web will know that Artemis has existed now for more than a decade. Hannity illustrates his incompetence right off the bat.
Duffy then proceeds to insist that the next Artemis mission, dubbed Artemis-2, will fly in April 2026 and send four astronauts around the Moon, followed by the Artemis-3 manned landing one year later.
Being an incompetent member of the propaganda press, Hannity of course accepts these claims without question. He fails to question Duffy about the serious issues with the Orion heat shield, which experienced extensive unexpected damage that is still not understood during its return on the first Artemis mission in 2022.
Nor does either Duffy or Hannity mention the fact that for Artemis to land humans on the Moon SpaceX’s Starship not only has to become operational for human passengers, it needs an in-orbit refueling capability that does not yet exist. I have full confidence that SpaceX will eventually succeed in achieving these benchmarks, but I also doubt it will be able to do it by mid-2027, as claimed by Duffy.
Duffy and Hannity however are not alone in living in this dream world. » Read more
The California Coastal Commission has now scheduled a meeting on August 14, 2025 to reconsider SpaceX’s request to double its launch rate at Vandenberg Space Force Base from 50 to 100 launches per year.
Though it has no real authority over the base, and though the Space Force has indicated it has no objections to SpaceX’s proposal, the commission rejected that increase in a 6-4 vote in October 2024, but did so not because the commissioners thought it would harm California’s beaches, but because they did not like Elon Musk’s endorsement and campaigning for Donald Trump during the election campaign.
SpaceX has subsequently sued, with a judge ruling two weeks ago that the suit can go forward. Based on the statements made by commissioners in October, SpaceX has an excellent case, and will likely win in court.
It appears the commission is now acting to possibly stave off that suit. The article at the link also notes that the make-up of the commission has changed since that October meeting, with at least one of the commissioners who expressed the most hate against Elon Musk, Gretchen Newsom, is no longer a member.
At the same time, the hostility to Musk and SpaceX for environmental reasons appears to still exist within the commission. Either way, in the end SpaceX’s launch rate at Vandenberg is going to increase, since the military is agreeable to the change.
According to a report in Russia’s state-run press today, the repairs to the air leak in the Russian Zvezda module on ISS have reduced the rate of air lose significantly, but have failed to eliminate it.
Long-term observations have shown that the leak in the interstitial chamber of the Zvezda module of the International Space Station, which was reported to have been fixed in June, is still ongoing, though its rate has slowed significantly, Roscosmos Executive Director of Manned Space Programs, special presidential envoy for international space cooperation Sergey Krikalyov said.
“The leak is ongoing. We continue our efforts to find and fix it, with the recent repairs having seriously reduced the rate of air leakage. For some time we even thought that we had found the last crack and sealed it, though long-term observations have shown that it (air loss – TASS) continues,” he told a press conference ahead of the launch of the Crew Dragon Endeavour spacecraft carrying the Crew-11 mission crew.
Even if Russia succeeds eventually in sealing the leak entirely, this does not solve a more fundamental problem, the existence of stress fractures in the hull of Zvezda that have caused the leaks. That module, built in the 1990s and the second oldest module on ISS, remains at serious risk of catastrophic failure due to these fractures. That the leak has not yet been sealed suggests that new cracks are steadily forming even as Russian astronauts patch older cracks.
Though they do not say so, officials at both Roscosmos, NASA, and their partners in Europe and Japan are all praying that the station can last until 2030, when they plan to retire and de-orbit it. They all know however that there is a great risk that Zvezda will not cooperate, and cause an unplanned shut down much earlier.
The recent passed reconciliation bill included a provision ordering the Smithsonian Air and Space Museum to transfer the space shuttle Discovery back to NASA so that it could be shipped to Houston for display, budgeting $85 million for the task.
The Smithsonian however is now opposing that provision, claiming Congress and the President had no authority to do so as it owns Discovery and had not agreed to the transfer.
In a formal response, the Smithsonian Institution says it owns Discovery, which, like the rest of its collection, is held in trust for the American public. The Smithsonian asserts that NASA transferred “all rights, title, interest and ownership” of the shuttle to the Institution in 2012, and that it is “part of the National Air and Space Museum’s mission and core function as a research facility and the repository of the national air and space collection.”
It does appear the Smithsonian might have a case, based on past precedent and the laws that established the institution as an independent entity. At the same time, Congress provides two-thirds of its funding, which surely gives Congress a say in its actions. Moreover, recent court rulings have generally ruled against such independent institutions, ruling that the Constitution does not allow Congress to cede either its authority or the President’s in such cases.
So, even if the Smithsonian should win in court, its funding could be threatened if it defies Congress. It will be entertaining to watch this kerfuffle play out.
Cutting off your nose to spite your face: The Ontario government yesterday canceled a $100 million Starlink contract it had with SpaceX to provide internet service to remote areas, doing so in retaliation to Trump’s tariffs.
Ontario Premier Doug Ford threatened to cancel the contract in February if U.S. tariffs on Canadian goods were imposed. He killed the deal in March when U.S. President Donald Trump moved ahead with tariffs. “It’s done, it’s gone,” Ford said at the time. “We won’t award contracts to people who enable and encourage economic attacks on our province … and our country.”
…Ford’s cancellation of the deal came as part of a suite of measures in retaliation to Trump’s tariffs. He pulled American booze off the shelves of LCBO stores in March and has said the U.S. booze ban will be kept in place until Trump removes his tariffs on Canada. Ford also banned American companies from bidding on $30 billion worth of procurement contracts the province awards each year. He also banned U.S. companies from bidding on contracts related to his $200-billion infrastructure plan to build highways, tunnels, transit, hospitals, and jails.
It appears the province had to pay SpaceX a penalty for canceling the contract, but the amount has not been revealed. The cancellation also leaves those rural areas stranded, as the government presently has no alternative service to offer.
China today successfully launched an Earth observation satellite for Pakistan, its solid-fueled Kuaizhou-1A rocket lifting off from its Xichang spaceport in southwest China.

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.

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.

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.
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.
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.
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.
SpaceX this evening successfully placed 28 more Starlink satellites in orbit, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.
The first stage completed its 26th flight, landing on a drone ship in the Atlantic.

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.
The Starlab design in 2025. Click
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.

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.

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.
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.

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.
