SpaceX issues 1st statement regarding Superheavy test explosion

9:27 am

Damaged Superheavy

SpaceX yesterday issued its first update regarding the explosion in the lower half of the Superheavy booster that it had planned to fly on the next orbital test flight.

Booster 18 suffered an anomaly during gas system pressure testing that we were conducting in advance of structural proof testing. No propellant was on the vehicle, and engines were not yet installed. The teams need time to investigate before we are confident of the cause. No one was injured as we maintain a safe distance for personnel during this type of testing. The site remains clear and we are working plans to safely reenter the site.

That no propellant was involved explains why the booster and test pad experienced relatively little damage. They were likely pumping nitrogen through the system to test it, and while something exploded, the gases were not volatile.

The picture to the right is a screen capture from aerial drone flights performed by RGV Aerial Photography and posted on nasaspaceflight.com. I have enhanced it to bring out the details. Note the lack of damage on all sides of the booster at its base. The explosion was clearly confined to the booster, and appears to have occurred from within.

SpaceX and Arianespace make launch predictions for ’25 and ’26

9:40 am

In separate announcements this week, officials from Arianespace and SpaceX revealed their launch plans for the rest of this year and next.

First, Arianespace officials revealed yesterday that it is hoping to do six to eight Ariane-6 launches in 2026.

During a post-flight conference following the launch of Sentinel-1D, Arianespace CEO David Cavaillès stated that while the company preferred to wait until next year to reveal details about its 2026 launch manifest, it was aiming to double its launch cadence. He added that a cadence of between six and eight next year “will be great.”

If the company does manage eight Ariane 6 flights in 2026, it will already be close to reaching the stated maximum launch cadence of between nine and ten flights per year. When asked if this cadence could be increased, Cavaillès explained that the decision would be driven by customer demand.

Since customer demand for Ariane-6 has been quite low, because of its high cost, don’t expect this launch rate to rise much higher. Arianespace’s only big contract is 18 launches for Amazon’s Kuiper constellation. Once that is completed it is not clear where much future business will be coming from, even with some bureaucrats lobbying the European Space Agency to require its members to use it. There are too many cheaper options available now, with many more coming on line, both in America and Europe.

Next, a SpaceX official noted at a conference this week that the company hopes to complete another 25 to 30 Falcon 9 launches before the end of the year.

“We’re aiming for around 170 — between 165 and 170 — which means 25 to 30 more launches to go,” Kiko Dontchev, the company’s vice president of launch, said during a Wednesday session at the Space Economy Summit 2025.

…All together, “we’ll get to 2,400, 2,200 [metric tons launched] or something like that, which is absurd in the grand scheme of where things have been,” he added. Historically, that is close to the global record for metric tons launched to space by all companies and nations — about 2,500 metric tons in 2024, according to Jonathan’s Space Report, compiled by astronomer Jonathan McDowell.

In other words, SpaceX hopes its Falcon 9 rocket will this year alone place in orbit almost the same tonnage launched previously by everyone in the three-quarters of a century since Sputnik.

Cavaillès’ forecast means the company is likely to get very close to its prediction for launches at the beginning of the year, 180, that also included its Superheavy/Starship test launches. Quite an amazing achievement.

And as Al Jolson once said, “You ain’t seen nothin’ yet!”

Someone is apparently considering putting a helicopter on Starship when it goes to Mars

2:53 pm

Potential Starship helicopter location

In my regular trolling through the images sent down from Mars Reconnaissance Orbiter (MRO), I sometimes come across things that imply truly exciting future missions. That happened when in 2019 I found a bunch of photos each labeled as a “candidate landing site for SpaceX Starship”. Without fanfare SpaceX had begun researching locations for where it intended to land Starship on Mars, in the northern lowland plains, research that it later solidified considerably.

Similarly, I have found MRO images in 2022 suggesting scientists were thinking of running a helicopter mission inside Valles Marineris, the largest canyon in the solar system. Another image in 2024 suggested that a helicopter mission might go to another region in Mars’s southern cratered highlands.

The image to the right, cropped, reduced, and sharpened to post here, is another new example of a potential Martian helicopter mission. It was taken on August 19, 2025 and is labeled provocatively “Characterize Possible Rotorcraft Landing Site.” Unlike the previous two proposed helicopter locations, however — which appeared to be aimed at uncertain NASA funding — this image’s location suggests it is far more certain, and might launch far sooner than you can imagine.

Two former NASA administrators express wildly different opinions on NASA’s Artemis lunar program

1:07 pm

At a symposium yesterday in Alabama, former NASA administrators Charles Bolden and Jim Bridenstine expressed strong opinions about the state of NASA’s Artemis lunar program and the chances of it getting humans back to Moon before the end of Trump’s term in office and before China.

What was surprising was how different those opinions were, and who said what. Strangely, the two men took positions that appeared to be fundamentally different than the presidents they represented.

Charles Bolden
Charles Bolden

Charles Bolden was administrator during Barack Obama’s presidency. Though that administration supported the transition to capitalism, it also was generally unenthusiastic about space exploration. Obama tasked Bolden with making NASA a Muslim outreach program, and in proposing a new goal for NASA he picked going to an asteroid, something no one in NASA or the space industry thought sensible. Not surprisingly, it never happened.

Bolden’s comments about Artemis however was surprisingly in line with what I have been proposing since December 2024, de-emphasize any effort to get back to the Moon and instead work to build up a thriving and very robust competitive space industry in low Earth orbit:

Duffy’s current messaging is insisting it’ll be accomplished before Trump’s term ends in January 2029, but Bolden isn’t buying it. “We cannot make it if we say we’ve got to do it by the end of the term or we’re going to do it before the Chinese. That doesn’t help industry.”

Instead the focus needs to be on what we’re trying to accomplish. “We may not make it by 2030, but that’s okay with me as long as we get there in 2031 better than they are with what they have. That’s what’s most important. That we live up to what we said we were going to do and we deliver for the rest of the world. Because the Chinese are not going to bring the rest of the world with them to the Moon. They don’t operate that way.” [emphasis mine]

In other words, the federal government should focus on helping that space industry grow, because a vibrant space industry will make colonizing the Moon and Mars far easier. And forget about fake deadlines. They don’t happen, and only act to distort what you are trying to accomplish.

Meanwhile, Jim Bridenstine, NASA administrator during Trump’s first term, continued to lambast SpaceX’s Starship lunar lander contract, saying it wasn’t getting the job done on time, and in order to beat the Chinese he demanded instead that the government begin a big government-controlled project to build a lander instead.

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

3:18 pm

Overview map

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

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

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

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

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

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

Fake blather from NASA administrator Sean Duffy to hide more Artemis delays

9:47 am

Sean Duffy
Sean Duffy: “Look at the shiny object!”

During a press interview yesterday, interim NASA administrator Sean Duffy revealed almost as an aside that NASA’s mid-2027 launch for the first Artemis manned lunar landing is no longer realistic, and that NASA is now targeting a 2028 launch date instead.

Duffy managed to hide this revelation by also announcing that he is re-opening the bidding for the manned lunar lander NASA will use on that third Artemis mission. To quote Duffy:

Now, SpaceX had the contract for Artemis III. By the way, I love SpaceX and it’s an amazing company, but the problem is, they are behind. They pushed their timelines out and we are in a race against China. The president and I want to get to the moon in this president’s term. So, I’m going to open up the contract and I’m going let other space companies compete with SpaceX, like Blue Origin. Whatever one gets us there first to the moon, we are going to take. If SpaceX is behind and Blue Origin can do it before them, good on Blue Origin.

By the way we might have two companies that can get us back to the Moon in 2028.

The propaganda press of course is going wild about this SpaceX announcement, making believe it signifies something of importance. “SpaceX is behind! Elon Musk can’t do it! Duffy is giving Jeff Bezos the job!” And as I think Duffy intended, everyone is ignoring the fact that NASA has now admitted it won’t meet that 2027 launch target.

The irony is that Duffy’s decision to re-open bidding on that manned mission is utterly meaningless. » Read more

Eleventh Starship/Superheavy a complete success

6:18 pm

Starship and Superheavy during ascent
Starship and Superheavy during ascent today.

On the eleventh orbital test flight today of Starship/Superheavy, SpaceX basically achieved all its engineering goals, with both Superheavy and Starship completing their flights as planned, with Superheavy doing a soft vertical splashdown in the Gulf of Mexico, and Starship doing a soft vertical splashdown in the Indian Ocean.

The Superheavy flown was on its second flight, having flown on test flight #8. Of its 33 Raptor engines, 24 had flown previously. In returning, it successfully used a new configuration of engine burns, first firing thirteen engines, then six, then three.

More significant was Starship’s flight. The engineers had purposely left tiles off in some locations that would experience the greatest heat during re-entry, to find out if the ship could survive a loss of those tiles. It did, and did so in a truly remarkable manner, always flying in a controlled manner, even as it attempted a radical and previously untried banking maneuver as it approached the ocean in order to simulate a return to the launch tower chopsticks at Boca Chica.

Prior to splashdown and during its coast phase, Starship once again successfully tested the deployment of eight dummy Starlink satellites, as well as a relight of one of its Raptor engines to demonstrate it will be able to do a planned de-orbit burn once it enters a full orbit on future test flights.

Once again, the word to describe this flight is remarkable. While no else has yet been able to recover a first stage and reuse it, SpaceX has been doing it with its Falcon 9 for almost a decade, and doing it hundreds of times.

And now it has twice reused a Superheavy booster, out of only eleven test launches. Based on this and the last test flight, the company will almost certainly begin reusing Starship prototypes during next year’s orbital test flights, when it will begin flying full orbits using its third version of Starship, including returns to Boca Chica for chopstick tower catches. Furthermore, expect the deployment of real Starlink satellites on those missions.

The next mission should likely take place close to the end of this year, and it should likely be followed by additional flights about every two months.

the inhabitants thereof.” Photo credit: William Zhang

While politicians and media swamp creatures focus on the relatively inconsequential race to do an Apollo-like manned landing on the Moon, the real American space program is being run privately by SpaceX, and its goal is to not only go to Mars, but to do so in a manner that will quickly establish a human colony. Along the way the company will help facilitate that government space program, but only as it helps SpaceX learn better how to get humans to Mars.

Most significantly, SpaceX is doing its space program entirely on its own dime. It is being financed by the revenues coming in to the company from the now more than seven million subscribers to Starlink. And those numbers will only rise with time, as Starship begins launching the next generation of satellites with capabilities that will dwarf all of SpaceX’s competitors.

Once again, freedom, private enterprise, and the American dream wins. May all humans someday live under rules that will allow them the same possibilities.

Watch the eleventh orbital test flight of SpaceX’s Starship/Superheavy rocket

8:32 am

The eleventh orbital test launch of Starship/Superheavy is scheduled for 6:15 (Central) today. It will be the last flight for version 2 of Starship, and will also include the second reuse of a Superheavy booster.

Starship will repeat its flight plan from the previous flight, testing the deployment of dummy Starlink satellites, the relighting of its Raptor engines once in orbit, and various new configurations of its thermal protection system. It will come down in the Indian Ocean, either controlled or not. Future flights will use version three, and quickly move towards orbital flights and a return to Boca Chica for a tower chopstick capture and later reuse.

Superheavy, which flew previously on the eighth test flight, will do more engine configuration tests on its return, and will attempt a soft vertical splashdown in the Gulf.

Court throws out environmental lawsuit against SpaceX, FAA, and Starship/Superheavy

8:45 am

The federal district court judge for the District of Columbia yesterday dismissed entirely the environmental lawsuit that had been filed against SpaceX and the FAA by anti-Musk activists following the first orbital test launch of Starship/Superheavy.

More details here. The lawsuit itself [pdf] was filed in 2023, claiming that the FAA’s environmental assessment of SpaceX’s activities at Boca Chica would do no harm to the environment were wrong.

SpaceX activities authorized in the FONSI/ROD [the environmental reassessment issued last year] have and will adversely affect the surrounding wildlife habitat and communities. In addition to harm from construction activities and increased vehicle traffic, rocket launches result in intense heat, noise, and light pollution. Furthermore, the rocket launches and testing result in explosions which spread debris across surrounding habitat and cause brush/forest fires — including one that recently burned 68 acres of adjacent National Wildlife Refuge. The FAA calls these explosions “anomalies,” but in fact they occur frequently, with at least 8 over the past 5 years. FAA acknowledged that many more such “anomalies” are expected over the next 5 years. The U.S. Fish and Wildlife Service has found that prior SpaceX rocket explosions harmed protected wildlife and designated habitat in violation of the Endangered Species Act (ESA).

At the time I noted this:

In other words, rockets and launch sites should never be placed inside wildlife refuges, because such activity is detrimental to wildlife.

A more false statement cannot be made. Under this conclusion the launch facilities at Cape Canaveral, which have been operating in the middle of a wildlife refuge now for more than six decades, should be shut down immediately. All the wildlife there must certainly be dead!

We have almost three-quarters of a century of empirical data in both Florida and California that spaceports are clearly beneficial to wildlife, because they actually create the refuge by reserving large areas where development cannot occur. This court decision merely confirms reality, something it appears increasingly the left doesn’t have much grasp of.

Update on what SpaceX learned about Starship’s tiles during the 10th test flight

11:27 am

Superheavy after its flight safely captured at Boca Chica
Superheavy after the October 2024 flight,
safely captured during the very first attempt

Link here. The update comes from a presentation given this week by Bill Gerstenmaier, SpaceX’s executive in charge of build and flight reliability, at the American Astronautical Society’s Glenn Space Technology Symposium in Cleveland.

Lots of new details. First, almost no tiles fell off during this flight. More significant, they found that the use of metal tiles won’t work. They tested three, and found that “The metal tiles… didn’t work so well.”

Gestenmaier also outlined how the flight provided the necessary data for sealing the gaps between the tiles better.

Gerstenmaier pointed to a patch of white near the top of Starship’s heat shield. This, he said, was caused by heat seeping between gaps in the tiles and eroding the underlying material, a thermal barrier derived from the heat shield on SpaceX’s Dragon spacecraft. Technicians also intentionally removed some tiles near Starship’s nose to test the vehicle’s response.

“It’s essentially a white material that sits on Dragon and it ablates away, and when it ablates, it creates this white residue,” Gerstenmaier said. “So, what that’s showing us is that we’re having heat essentially get into that region between the tiles, go underneath the tiles, and this ablative structure is then ablating underneath. So, we learned that we need to seal the tiles.”

They hope to do the 11th test flight in October, repeating the same suborbital configuration of previous flights, using the same version 2 of Starship. The plan will then be to follow up with a first suborbital flight of version 3 in 2026, followed quickly by orbital flights. During one of those orbital flights they will also try to do a chopstick catch of Starship. They also hope to do the first refueling tests next year.

All in all, it appears the test program is proceeding as hoped, and is about to accelerate significantly.

SpaceX gets major tax credit for the jobs its new Starship factory will create.

1:29 pm

Because SpaceX’s new Starship factory, dubbed Gigabay, will create more than 500 new jobs in the Boca Chica region, the Starbase city commission this week awarded the company a sales tax refund valued as much as $3.75 million.

Gigabay will create about 630 new jobs, according to information Barrera showed the City Commission. That number included 315 entry-level jobs, which pay nearly $50,000 a year; 277 staff jobs, which pay nearly $90,000 a year; and 26 manager positions, which pay about $164,000 a year. … At least 25% of the jobs must be filled by veterans, residents of the enterprise zone or people who are considered economically disadvantaged.

SpaceX may receive a sales tax refund of $7,500 per job if the company invests $250 million. The program is capped at 500 jobs, allowing SpaceX to receive a maximum of $3,750,000.

Once again, the opposition to SpaceX does not come from the general public, which overwhelming supports what the company is doing in south Texas because of the wealth it is bringing to the region. The only opposition comes from fringe and very tiny leftist activist groups who oppose anything new, and specifically hate Elon Musk because he backed Donald Trump in last year’s election.

Sadly, those fringe groups are also backed by the propaganda press, which gives them a loud bullhorn they don’t deserve. It is imperative that Texas politicians recognize these facts, and not let that bullhorn bully them into actions detrimental to their constituents.

Oh by the way, the FAA has approved the August 24th launch of Starship/Superheavy

12:07 pm

Increasingly irrelevant in the right places
Increasingly irrelevant in the right places

My headline reflects the sense of utter irrelevance of the FAA in announcing its approval of the launch licence for the tenth test launch of Starship/Superheavy (now scheduled for August 24, 2025) as well as its “closing” of its “investigation” into the failure during test flight nine.

As per the FAA in its statement, “There are no reports of public injury or damage to public property. The FAA oversaw and accepted the findings of the SpaceX-led investigation. The final mishap report cites the probable root cause for the loss of the Starship vehicle as a failure of a fuel component. SpaceX identified corrective actions to prevent a reoccurrence of the event.”

The FAA did not “oversee” SpaceX’s investigation. No one at the FAA has the slightest qualifications for doing so. All its bureaucrats did is sit in and watch, and when SpaceX’s engineers completed their work and “identified corrective actions,” the FAA paper-pushers pushed some paper to rubber stamp those conclusions.

Moreover, unlike during the Biden administration, the FAA did not waste any time or money retyping the SpaceX investigation. They simply approved it as is, and issued the launch license. And they apparently instantly agreed to the schedule proposed by SpaceX. In fact, it appears almost as if SpaceX announced the date before the FAA announced the license approval.

Elections matter. And they would matter less if we had had the sense in the past century to not cede so much power to an unelected federal bureaucracy that is really unfit to do the work we gave them. The goal now should be to take that power away from them, and to do it as quickly as it is humanely possible.

It appears at least when it comes to FAA launch licenses, Trump has made some significant progress towards this goal.

A protest of boats now intends to violate the range and prevent the next Starship/Superheavy test launch

1:15 pm

Protest announcement.
Protest announcement. Click for original.

A Mexico activist group now plans to launch a fleet of boats that plan to violate the range and prevent the next Starship/Superheavy test launch.

A translated version of the protest announcement can be seen to the right. From the first link above:

A Mexican environmental group, Comité Global A.C., said it plans to protest the launch by sending boats into the Gulf of Mexico near Starbase. If they enter designated safety areas during the planned launch period, they could delay the mission.

The group’s leader said the Matamoros Port Authority gave permission for the protest dubbed “Operación Golfo de México.” It will also include protesters on Playa Bagdad, a Mexican beach just south of the Rio Grande where people often gather for Starship launches.

I have not yet gotten confirmation that the local port authority has approved this protest as the organization claims, but it also appears that this activist group intends to show up in boats regardless. If so, this protest could easily cause the next test launch, now scheduled for August 24, 2025, to be delayed endlessly.

It seems this is a matter for Trump and the Coast Guard. Someone must move in and remove these boats, arresting and fining the occupants for violating launch range restrictions that apply to all international waters.

Update on next Starship/Superheavy launch

10:06 am

Superheavy after its flight safely captured at Boca Chica
Superheavy after the October 2024 flight,
safely captured during the very first attempt

Link here.

SpaceX now appears to have completed the prelaunch testing of Starship prototype #37, having tested the ship again after swapping out an engine after the first static fire test. It is now moving to put Superheavy on the launchpad for its own static fire tests.

The bottom line is that SpaceX appears moving successfully towards a launch of the next test flight of Superheavy/Starship, its tenth, for sometime between August 22nd and August 28th.

The report also describes the company’s work to preserve Superheavy prototype #12, the first to be captured and recovered during the fifth orbital test flight in October 2024.

The picture to the right shows that Superheavy booster, hanging from the chopsticks just after it was captured.

Italy to fly experiments on first Starship flights to Mars

10:31 am

According to a tweet by SpaceX’s president and chief operating officer Gywnne Shotwell today, the Italian Space Agency (ASI) has signed an agreement to fly experiments on first Starship flights to Mars that will carrying customer payloads. She quoted a tweet by ASI’s president, Teodoro Valente:

ASI_Spazio and SpaceX have signed a first-of-its-kind agreement to carry Italian experiments on the first Starship flights to Mars with customers. The payloads will gather scientific data during the missions. Italy continues to lead in space exploration!

Little other information has yet been released, but expect more details in the coming days.

UPDATE: ASI’s press release on August 8th added this detail:

The payloads will include a plant growth experiment, a weather monitoring station and a radiation sensor. The goal is to collect scientific data in the approximately six-month interplanetary flight phase from Earth to Mars and then on the Martian surface.

The word that best describes our present NASA lunar program is “delusional.”

12:16 pm

Artemis, a program based on fantasy
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

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.

Mexico’s president says it will investigate SpaceX for doing salvage operations off its coast

9:26 am

Mexico to SpaceX:
Mexico to SpaceX: “Nice business you got here. Shame
if something happened to it.”

You can’t win with these people: First Mexico’s president Claudia Sheinbaum complained loudly about the debris that landed or washed up on its beaches after several of SpaceX’s Starship/Superheavy test launches, demanding an investigation followed by sanctions against the company.

Now Sheinbaum is complaining and demanding a new investigation about SpaceX’s effort the last two weeks to salvage and remove that debris from the ocean off its coast.

During a passage of her daily press conference, Sheinbaum said the agencies are analyzing whether the company has to be sanctioned after its unit tasked with clearing debris from the Starship launch, located in the Gulf of Mexico, worked without proper authorization. “We are investigating but the Environment, Navy, Digital Transformation, Government and Foreign Relations secretariats are conducting their research. The study is practically done,” Sheinbaum said.

Navy Secretary Raymundo Pedro Morales Angeles said the company hired by SpaceX to retrieve debris from its Starship rocket was allowed to enter the country but didn’t fulfill the requirements to work and ended up leaving the country.

If this behavior doesn’t prove Sheinbaum’s lust for power and control, nothing will. She doesn’t really care about Mexico’s beaches or environment. If she did, she would celebrate SpaceX’s salvage operations. What she really doesn’t like is that someone is doing something without her permission. She is the boss, and SpaceX better remember that!

Is SpaceX doing ocean salvage operations near Boca Chica?

11:25 pm

Superheavy aft section being salvaged
Click for original source.

SpaceX appears to be recovering the Superheavy booster that soft landed off shore from Boca Chica during the sixth test flight in November.

On Saturday, footage, albeit from a vantage point of someone who should not have been that close to the recovery operations, showed the aft end of a Booster with most of its Raptor engines still attached, being lifted out of the water.

During that November flight mission controllers decided against attempting a chopstick recovery, and sent the booster to do a soft vertical spashdown just off the coast. The booster than fell over and was seen drifting south. It appears SpaceX has now mounted operations to recovery it, possibly in response to the complaints by Mexican officials about its rocket pieces showing up on the beaches. Company engineers likely also wish to take a look at the equipment for their own reasons.

Musk: 10th Starship/Superheavy launch in “about three weeks”

12:31 pm

According to a very short tweet Elon Musk posted on July 15, 2025, SpaceX will attempt the 10th orbital test flight of Starship/Superheavy in “about three weeks.”

Musk however provided little information. This is the full text of his tweet:

Launching again in ~3 weeks

The lack of information raises more questions than it answers. For example, how is SpaceX replacing the destroyed Starship that blew up during a static fire test in June on its Massey test stand at Boca Chica? I assume it is using another prototype already in the assembly line, but will it be a version 2 prototype that the company has flown on the past three flights that failed each time after stage separation from Superheavy? Or has SpaceX dumped the prototypes of version 2 and shifted directly to version 3 because of those failures?

How is it going to do its Starship prelaunch static fire tests? Has it gotten its Massey test stand repaired that quickly, or has it found other options? Earlier reports suggested fixing the stand would take much longer. Furthermore, there was the question of fixing it for version 2 or version 3, which require different configurations. Fixing it for version 2 suggested this would delay bringing version 3 on line.

This tweet raises more questions than it answers. However, if Musk is even close to correct than many of these questions will be answered in only a week or two, since that is when prelaunch static fire test must begin.

SpaceX planning to use Starship for manufacturing in space

It appears the enthusiastic investment response last week to the potential of using Varda’s re-turnable capsule for manufacturing in space (especially of pharmceuticals) has caught SpaceX’s interest. According to a news report yesterday, SpaceX has now begun developing a program to use Starship for the same purpose, delivering the raw materials in orbit for short or long periods while these products are produced automatically and then returning them for sale on Earth.

Under the plan, internally called Starfall, SpaceX’s Starship rocket would bring products such as pharmaceutical components to space in small, uncrewed capsules, said one of the people, who spoke on condition of anonymity because the matter is confidential.

Starship would then deploy the capsules, which would spend time in orbit before reentering the atmosphere, where they could be recovered back on Earth, the person added.

This description by this anonymous source seems inaccurate however. Why even consider using these small separate capsules when the entire operation can be put inside Starship, which can then bring everything home when ready? Moreover, Starship’s ability to put a lot of mass in a large space up into orbit gives it an great advantage over the smaller capsules being developed by companies like Varda.

Either way, the advantages of weightlessness for producing products for profit are finally being realized, after decades of blockage by government intransigence. Since the Challenger accident in 1986 and Reagan’s order that the shuttle would no longer not be used for commercial purposes, NASA has forbidden production on its spacecraft and ISS of any products for sale afterward.

Now that the cost of launch has dropped significantly (Thank you Elon Musk!), many investors and companies are seeing great potential for manufacturing in space. And those profits will help feed a private space industry, making the government agency of NASA even more irrelevant.

SpaceX gets approval to build oxygen plant at Boca Chica

1:03 pm

SpaceX today received the okay from Cameron County to build a plant at Boca Chica to produce oxygen from the atmosphere for use in its Superheavy/Starship rocket.

The commissioners voted, 3-1, to give Elon Musk’s rocket company a beachfront construction certificate and dune protection permit, allowing the company to build a modern-day factory akin to an oil refinery to produce gases needed for space flight launches.

The plant will consist of 20 structures on 1.66 acres. The enclosed site will include a tower that will reach 159 feet, or about 15 stories high, much shorter than the nearby launch tower, which stretches 480 feet high. It is set to be built about 280 feet inland from the line of vegetation, which is where the dunes begin. The factory will separate air into nitrogen and oxygen. SpaceX utilizes liquid oxygen as a propellant and liquid nitrogen for testing and operations.

By having the facility on site, SpaceX hopes to make the delivery of those gases more efficient by eliminating the need to have dozens of trucks deliver them from Brownsville. The company says they need more than 200 trucks of liquid nitrogen and oxygen delivered for each launch, a SpaceX engineer told the county during a meeting last week.

As usual, the same cranks who always complain about this stuff are given space by this news outlet to whine, but the truth is that the commission’s vote well reflects the attitude of the local community. It supports what SpaceX is doing, because of the prosperity the company is bringing to this formerly depressed region.

Moreover, this facility will not only save SpaceX money and make it easier to launch more frequently, it is likely environmentally beneficial. I suspect the facility will be relatively clean compared to the truck convoys it will replace.

Sightseeing near Starship’s candidate Martian landing sites

2:21 pm

An interesting mesa near Starship's Martian landing zone
Click for original image.

Today’s cool image takes us sightseeing in the region on Mars that SpaceX has chosen for its prime landing zone for its Starship spaceship. The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 29, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows a 465-foot-high unusually shaped mesa in this region.

The full resolution inset at the bottom of the picture focuses at the strange tilted layers on the southern slope of this mesa. Apparently the layers at this spot were pushed sideways so they lie significantly angled to the horizontal. Though it isn’t clear from this picture, it is possible that the mesa itself is made up of similar tilted layers, hidden below the surface. We can see the tilt only on the mesa’s southern flank because erosion has apparently exposed it.

Note also the black stain that surrounds the mesa. Though this might be caused by wind distributing dust, such stains have also been seen at a location where scientists suspect an inactive hot spring might exist, as well as another location where there may have been relatively recent volcanic activity.

Is this stain caused by any of these processes? In situ exploration would probably be necessary to find out. And we may soon actually have spaceships landing here in the relatively near future with the capability to do this.

Update on SpaceX’s plans to resume Starship/Superheavy flight testing

9:37 am

Link here. The article provides a detailed overview of the situation at Boca Chica following the static fire explosion of a Starship on June 18, 2025, which badly damaged the Masseys test stand used by Starship prior to launches.

The problem facing the company is that it wants to fly the last few version-two Starships (called Block 2) before it is ready to switch to the upgraded Block 3, and these two versions apparently require a different set up on the test stand. The article outlines three options, with the first two the simplest and most straightforward, but require the most delays.

Option three, which is the most SpaceX-like of them all, would involve the repair Masseys for Block 3 and, in parallel, attempt to come up with a plan to static fire Ships on Orbital Launch Pad 1 (A). This would allow SpaceX to continue testing and flying the remaining Block 2 Ships while preparing for Block 3 of Starship. This is what SpaceX is planning.

In other words, do Block 2 Starship prelaunch static fire tests on the launchpad itself while Masseys is being rebuilt for Block 3.

The article outlines in detail the technical difficulties this plan requires, because the launch mount is also used for prelaunch static fire tests of Superheavy. The two rockets require different mount clamping and fueling systems.

If this is the plan that SpaceX is following, it will likely mean that the next test flight, the tenth, will occur in about two months, maybe sooner. We will get a better idea of the company’s plans in the coming weeks.

Mexican president threatens action against SpaceX at Boca Chica

9:08 am

The president of Mexico, Claudia Sheinbaum, yesterday indicated that her government was considering taking legal action against SpaceX because of the debris from its Superheavy rocket that was found washed up on its beaches after a test launch.

Mexico’s government was studying which international laws were being violated in order to file “the necessary lawsuits” because “there is indeed contamination”, Sheinbaum told her morning news conference on Wednesday.

…Mexican officials are carrying out a “comprehensive review” of the environmental impacts of the rocket launches for the neighboring state of Tamaulipas, Sheinbaum said.

Other than this one quote, the article at the link is largely junk, focusing on the test stand explosion last week of Starship, an event that has nothing to do with the material found on Mexico’s beaches. Moreover, that debris was apparently so harmless Mexicans were able to quickly gather it for souvenirs, with some immediately making money from it by selling it on social media.

In other words, this “investigation” and this “reporting” is nothing more than anti-Musk rhetoric because Musk has aligned himself with Trump.

SpaceX provides update on Starship explosion while fueling for static fire engine test

1:02 pm

SpaceX has now posted an update outlining its preliminary conclusions as to the cause of the Starship explosion as the spacecraft was being fueled prior to a static fire engine test on June 18, 2025.

Engineering teams are actively investigating the incident and will follow established procedures to determine root cause. Initial analysis indicates the potential failure of a pressurized tank known as a COPV, or composite overwrapped pressure vessel, containing gaseous nitrogen in Starship’s nosecone area, but the full data review is ongoing. There is no commonality between the COPVs used on Starship and SpaceX’s Falcon rockets.

It remains unclear how long it will take to get that test stand back up and running.

Major explosion during preparations for static fire test of Starship prototype

11:14 pm

The moment the explosion begins on this Starship prototype<

As engineers tonight were preparing for a standard static fire engine test at Boca Chica of the next Starship prototype, expected to fly on the tenth Starship/Superheavy test flight, the spacecraft suddenly exploded.

I have embedded video of the explosion below. The event occurred prior to the actual static fire test, while Starship’s tanks were being filled. The image to the right is a screen capture just as the explosion begins. The white cloud is the initial release from the explosion (not standard venting), with the red dot indicating the location where the event began. It appears very much to have started inside this Starship spacecraft, which SpaceX was preparing for the next test flight.

Fortunately, no injuries have been reported.

Obviously, this is going to delay somewhat that tenth test flight. SpaceX has more Starship prototypes ready to go, but the company must first figure out what went wrong in this case. It also appears there might be some damage to that test stand, which will also have to be rebuilt so that future static fire tests of upcoming Starships can take place.

Mexican officials demand investigation into Starship/Superheavy debris on its beaches

11:23 am

Mexican officials of the border state adjacent to Texas are now demanding an investigation into Starship/Superheavy debris that has been found recent on its coast, claiming SpaceX is “polluting Mexican beaches.”

Karina Lizeth Saldivar, the head of the Tamaulipas Secretariat for Urban Development and Environment, recently announced that they would be requesting that federal authorities in Mexico investigate the damages and potential damages that rocket fragments could cause.

According to Saldivar, the rocket pieces could pose a potential danger to locals and claimed that her agency would request a formal investigation by Mexican federal environmental agencies. It remains unclear if Mexico’s government could do anything about the issue.

Saldivar is a typical government apparachik. Rather than try to develop the beach area in Mexico that is close to Boca Chica and thus provides a great tourist spot for viewing launches, she instead can only whine and demand the government shut things down.

Meanwhile, the article notes that ordinary Mexicans aren’t complaining. Instead, they have been collecting the rocket pieces enthusiastically, with some making money by selling them as collector’s iten on social media.

Air Force issues impact statement for SpaceX’s proposed Cape Canaveral Starship/Superheavy launch site

2:04 pm

Map of proposed Cape Canaveral Starship/Superheavy launch facilities
Click for higher resolution version.

The Air Force today released its environmental impact statement for SpaceX’s proposed Starship/Superheavy launch site at Cape Canaveral, generally approving a launch rate of 76 launches per year, noting that this would cause “no significant impact” on the environment while providing “beneficial impact” on the local economy.

You can read the impact statement here [pdf]. It lists 69 areas where these new operations could impact something, and found in almost all no significant impact. The beneficial impact was found in the areas where the operations would boost the local economy.

The single area where these additional launches might have an impact is the issue of noise, noting that “community annoyance may increase” due to the launches. Considering the wealth that the local community will gain from jobs, industry, and tourism due to those launches, I suspect the only whining about this noise will come from fake environmental groups opposed to anyone doing anything.

None of this is any surprise. Launches have been occurring at Cape Canaveral and the Kennedy Space Center for more than three quarters of a century, and the only significant impact to the ecology has been beneficial, reserving large areas from development where wildlife has prospered. If anything, the obviousness of this proves the utter waste of money we now spend on such reports.

The statement notes that it still will require FAA input on coordinating the closure of air space during launches, but it also appears to consider this part of normal routine actions, not a requirement the FAA can use to block operations or approval.

The number of proposed launches however is quite impressive. SpaceX’s plan would close to match the annual number of global launches by everyone for most of the space era. Nor is it impossible considering the design of the rocket and the plans the company has for getting to Mars. The site plan includes two launch mounts for Starship/Superheavy (as shown in the map above). This is in addition to the two Starship/Superheavy launch facilities the company wants to build at Kennedy.

The statement is now open to public comment through July 28, 2025. The Air Force also plans three public meetings in the Cape Canaveral area on July 8, 9, and 10. It will also make a fourth virtual public meeting available from July 15 to July 28.

In demanding an investigation by SpaceX into the Starship failure on this week’s test flight, the FAA puffs up its chest and pounds it like a chimpanzee

11:44 am

My heart be still: As reported in numerous propaganda media outlets today, the FAA has announced that it is demanding an investigation by SpaceX into the fuel leaks that caused Starship to tumble and then burn up in an uncontrolled manner as it came down in its designated landing zone in the Indian Ocean. From the FAA’s statement:

The FAA is requiring SpaceX to conduct a mishap investigation for the Starship Flight 9 mission that launched on May 27 from Starbase, Texas. All Starship vehicle and Super Heavy booster debris landed within the designated hazard areas. There are no reports of public injury or damage to public property. The mishap investigation is focused only on the loss of the Starship vehicle which did not complete its launch or reentry as planned.

This FAA demand for an investigation is meaningless and not news, because SpaceX doesn’t need the FAA to require it. Does anything think SpaceX wasn’t going to do an investigation without an order from the FAA?

Nor will the FAA’s demand change anything. Once SpaceX completes and submits its investigation, the FAA will approve it immediately. No one at the FAA is qualified to question it. The FAA might participate in that investigation as an outside observer and add some value, but in the end the investigation and subsequent actions are entirely in SpaceX’s hands.

The FAA also admits that even though Starship came back out of orbit in an uncontrolled manner, breaking up over the Indian Ocean, it did so exactly as the mission’s contingency plans intended. No one was hurt. Nothing was damaged on the ground. And all the debris fell within the designated landing zone. From the FAA’s legal perspective, there is nothing to investigate, since its only responsibility is to limit harm to the public. SpaceX did what was requested, most admirably. The FAA admits as much in not requiring a mishap investigation of the Superheavy failure.

That the propaganda press is trying to make a big deal about this is a joke. These press reports are merely more propaganda attempting to pump up the importance of government power while denigrating anything to do with Elon Musk.
