Exoplanet detected inside gap in accretion disk surrounding a Sunlike star

9:30 am

Exoplanet in gap of disk

For the first time since 2018, scientists have obtained a clear detection of an exoplanet inside the accretion disk surrounding a Sunlike star. Furthermore, the planet sits inside a gap in that accretion disk, the first time such an exoplanet has been found.

The image to the right, taken from figure one of the research paper [pdf], shows the exoplanet, dubbed WISPIT 2b. The star, located about 435 light years away, has a mass only slightly larger than our Sun, and is considered a close match. The planet itself is estimated to be about the mass of Jupiter, though its orbit within that gap is much farther away, 57 astronomical units versus 5.2. It is these details that make the discovery significant. From the paper’s conclusion:

As the planet resides in the cleared gap and its mass is consistent with the modeled planet mass required to open such a gap, we argue that it likely formed in situ through core accretion and that there is no rapid migration on dynamical timescales. Future follow-up observations of WISPIT 2b with ALMA and [Webb] will enable studies of its atmosphere and the impact of the embedded planet on the disk’s gas kinematics and surface density structure. This will allow us to calibrate ALMA observations of other embedded planet candidates, to unlock the full potential of this complementary technique.

…The discovery of WISPIT 2b embedded in the gap of a seemingly unperturbed disk demonstrates, for the first time, that wide-separation gas giants, discovered by direct imaging around older systems, can indeed form in situ. Thus, WISPIT 2b marks a promising starting point to study wide separation planets in time.

It has long been theorized that gas giants can form much farther from their star, and then migrate inward as the system evolves. This discovery counters that supposition, or least demonstrates that it does not have to occur in every new solar system.

The image also shows that the accretion disk has a second gap farther out, as well as a cleared area close to the star, comparable in size to our solar system. Though other exoplanets have not been detected yet, these gaps suggest they exist, thus indicating that a solar system comparable to our own is now forming.

A baby star and its protoplanetary disk

A baby star and its protoplanetary disk
Click for originial.

Cool image time! The picture to the right, cropped, rotated, reduced, and sharpened to post here, is the Webb picture of the month from NASA and the European Space Agency (ESA), released today. It shows a baby star about 525 light years away.

IRAS 04302+2247, or IRAS 04302 for short, is a beautiful example of a protostar – a young star that is still gathering mass from its environment – surrounded by a protoplanetary disc in which baby planets might be forming. Webb is able to measure the disc at 65 billion km across – several times the diameter of our Solar System. From Webb’s vantage point, IRAS 04302’s disc is oriented edge-on, so we see it as a narrow, dark line of dusty gas that blocks the light from the budding protostar at its centre. This dusty gas is fuel for planet formation, providing an environment within which young planets can bulk up and pack on mass.

When seen face-on, protoplanetary discs can have a variety of structures like rings, gaps and spirals. These structures can be signs of baby planets that are burrowing through the dusty disc, or they can point to phenomena unrelated to planets, like gravitational instabilities or regions where dust grains are trapped. The edge-on view of IRAS 04302’s disc shows instead the vertical structure, including how thick the dusty disk is. Dust grains migrate to the midplane of the disc, settle there and form a thin, dense layer that is conducive to planet formation; the thickness of the disc is a measure of how efficient this process has been.

The dense streak of dusty gas that runs vertically across this image cocoons IRAS 04302, blotting out its bright light such that Webb can more easily image the delicate structures around it. As a result, we’re treated to the sight of two gauzy nebulas on either side of the disc. These are reflection nebulas, illuminated by light from the central protostar reflecting off of the nebular material.

As this is a baby star, the cones above and below the disk indicate the original spherical cloud, with the upper and lower halves now being pulled downward into a spinning disk, where the solar system is forming.

This image is not simply an infrared Webb image. The Hubble Space Telescope provided the optical view, which the Atacama Large Millimetre/submillimetre Array (ALMA) in Chile provided data in those wavelengths. Note also the many background galaxies. The universe is not only infinite, it is infinitely populated.

Perseverance looks west

Perseverance looks west
Click for full resolution. For original images go here and here.

Overview map
Click for interactive map.

Cool image time! The panorama above, reduced and sharpened to post here, was created using two pictures taken on August 28, 2025 by the left navigation camera on the Mars rover Perseverance (here and here).

The blue dot on the overview map to the right marks Perseverance’s location when it took these pictures. The yellow lines indicate the approximate area covered by the panorama. The red dotted line indicates the rover’s planned route, with the white dotted line its actual travels.

The recent geological research focused on the lighter-colored ridge on the right center, dubbed Soroya. From the August 27, 2025 update by the science team:

Soroya was first picked out from orbital images as a target of interest because, as can be seen in the above image, it appears as a much lighter color compared to the surroundings. In previous landscape images from the surface, Mars 2020 scientists have been able to pick out the light-toned Soryoa outcrop, and they noted it forms a ridge-like structure, protruding above the surface. Soroya was easily identifiable from rover images as Perseverance approached since it indeed rises above the surrounding low-lying terrain.

The view is looking downhill away from Jezero Crater. The curve of the horizon is an artifact of the navigation camera’s wide view, accentuated by the slope that the rover sits on. The low resolution of this western region on the overview map is because the science team has not yet had Mars Reconnaissance Orbiter (MRO) get highest resolution pictures there yet.

Note the utter barrenness of this terrain. This is Mars, a lifeless world that has only the future potential for life, once we humans start to colonize it. Whether there was ever any past life remains uncertain, but the nature of its terrain as seen by both Perseverance and Curiosity suggests strongly that past life never existed, or if it did it barely survived and was quickly wiped out, a long time ago.

Mars’ interior is more chaotic than Earth’s

9:15 am

Martian quake map as seen by InSight
The largest quakes detected by InSight, indicated
by the red dots.

Using archival quake data from the Mars lander InSight, scientists now believe that the upper layers in the interior of the red planet are not as coherently layered as the Earth’s, that its mantle is broken up in a much more chaotic manner. From the paper’s abstract:

We report the discovery of kilometer-scale heterogeneities throughout Mars’ mantle, detected seismically through pronounced wavefront distortion of energy arriving from deeply probing marsquakes. These heterogeneities, likely remnants of the planet’s formation, imply a mantle that has undergone limited mixing driven by sluggish convection. Their size and survival constrain Mars’ poorly known mantle rheology, indicating a high viscosity.

These “heterogeneities” are large blocks of material, some as large as two to three miles wide, that are thought left over from the planet’s initial formation. These initial pieces of the mantle were layered like the Earth, but subsequent impacts during the accretion process cracked them and shifted them about.

These results have some uncertainty, as so far only one seismometer, InSight’s, has be placed on Mars. It will require more sensors and years of data to fully map the interior with greater precision and reliability.

Another great hiking location on Mars

Another great hiking location on Mars
Click for original image.

In honor of our just completed visit to the south rim of the Grand Canyon, today’s cool image takes us to another location on Mars that to me appears a perfect place to install some hiking trails. The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 30, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The image shows a two-mile wide canyon with a number of scattered narrow mesas within. The north and south rims rise about 550 feet above the canyon floor. The two mesas labeled “A” and “B” rise about 200 and 100 feet respectively.

The hiker in me immediately imagines what a great hike it would be to go up the western nose of either ridge and walk along its crest. The knife-edge nature of ridge “A” would mean that for a large majority of the hike you’d be at the north and south edges at the same time.

Sand dunes inside the Martian north polar icecap

Sand dunes inside the Martian north polar icecap
Click for original image.

Today’s cool image returns to the Martian north pole. The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on July 3, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the top of a ridge near the edge of that icecap, with dunes visible in the hollow several thousand feet below.

The angle of this picture does not show us the many layers on the cliff leading down to those dunes. It does show evidence, however, of the top few layers on the flat crest of that ridge. The white lines delineate those layers, each line marking the edge of a series of wide terraces.

The dunes in the canyon below are of interest because their source is likely the dust that is mixed into thick icecap’s ice. As that ice sublimates away on the face of the cliff, the dust falls into the canyon, where it is trapped.

The beauty of Mars’ many-layered northern icecap

The beauty of Mars' ice cap
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on July 1, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels it clumsily as “North Polar layered deposits structural geology in icy layers”. What we see are the many layers that make up the north polar cap, produced by the red planet’s many climate cycles that scientists think Mars has undergone over the eons as the red planet’s rotational tilt, or obliquity, rocked back and forth from 11 degrees inclination to as much as 60 degrees. At the extremes, the ice cap was either growing or shrinking, while today (at 25 degrees inclination) it appears to be in a steady state.

These layers are a mixture of ice and dust. The variations from dark to light likely indicate changes in the amount of dust in the atmosphere. Dark layers suggest the atmosphere was more dusty due to volcanic eruptions. Light layers suggest the planet’s volcanic activity was more subdued.

At least that’s one hypothesis.

Wind-eroded terrain on the edge of Mars’ largest volcanic ash field

Wind-eroded terrain in Mars' largest volcanic ash field

Cool image time! The picture to the right, cropped and sharpened to post here, was taken on July 2, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Labeled simply as “wavy terrain” by the MRO science team, it shows a relatively flat plain of hollows and terraced ridges that suggest the prevailing winds come from the west-southwest. As they blow, they slowly cause the layers of material to peel away, exposing those terraces.

This wavy landscape extends for many miles to the west, covering a region 135 by 160 miles in area. The layering and wavy nature of the terrain suggests the material here is fragile and easily peeled away by the winds of Mars’ very thin atmosphere. Think of the sandstone that forms Monument Valley and Canyonlands in the southwest United States, shaped almost entirely by wind.

And in fact, the overview map below confirms this.

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.

Texas brewery tries brewing beer and growing barley on ISS

1:19 pm

A Texas brewery dubbed Starbase Brewing (no connection to SpaceX) has just completed an experiment on ISS where it tried to brew beer in weightlessness as well as grow barley in simulated Martian soil.

Starbase Brewing — unrelated to Elon Musk’s space company or its South Texas city of Starbase — sent its MicroBrew-1 and OASIS experiments to the International Space Station aboard a SpaceX mission Aug. 1. They came back aboard a SpaceX Dragon spacecraft that splashed down eight days later off the coast of California.

…OASIS, short for “Optimizing Agriculture in Simulated Interplanetary Soils,” is the result of a partnership between the beer maker, Texas A&M AgriLife and Jaguar Space, a Colorado bioastronautics firm. According to Argroves, who launched the company in 2020, the goal was to grow barley in a mixture of Martian soil simulant with a byproduct of beermaking called Brewer’s Spent Grain and microbes.

The MicroBrew-1 experiment attempted to ferment beer, mixing “eight containers loaded with half wort — the sugary liquid extracted from malted grains — and half yeast.”

The company is far from manufacturing space-grown beer, but its founder seems focused on being the first brewery selling beer on Mars.

New Horizons placed in hibernation, possibly forever

9:05 am

The science team running the New Horizons probe, now more then 5.7 billion miles from Earth, has placed the spacecraft into what will be its longest hibernation period so far, with the possibility that it could even last forever.

New Horizons, which had been in active data-collection mode since April, will now remain in hibernation. Pending a final Fiscal Year 2026 budget, the spacecraft may be awoken in late June 2026. This will be the longest hibernation period of the mission so far, surpassing the previous mark of 273 days from June 2022 to March 2023.

But the spacecraft won’t be completely at rest; New Horizons will continue to take round-the-clock measurements of the charged-particle environment in the Sun’s outer heliosphere and the dust environment of the Kuiper Belt using three different onboard scientific instruments. These data will be transmitted back to Earth when New Horizons wakes up. [emphasis mine]

Though the NASA press release puts up an optimistic front, it is very likely that this hibernation period will last significantly longer than planned, due to those budget negotiations. Trump’s budget proposes eliminating all funding for New Horizons, which will mean this hibernation period will be permanent. There will be no money to hire anyone to reactivate it.

Even if the budget is cut, it is probable that NASA management in the future will provide some cash. At the moment there is little for it to observe on a daily basis. All that needs to be done is to turn it on for short periods to download the heliosphere data. Management could simply decide to turn it on once every five years or so.

SpaceX tonight successfully launched the Space Force’s X-37B mini-shuttle, its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida.

This is the eighth mission for the Space Force’s two X-37Bs. It appears this flight is fourth for this particular X-37B, but this is not confirmed. Nor do we know how long this particular will last in orbit.

SpaceX’s first stage completed its sixth flight, landing back at Cape Canaveral. The fairing halves completed their first and second flights respectively.

Using Webb astronomers have for the first time identified the source of a fast radio burst

12:02 pm

Fast Radio Burst source

Astronomers using the Webb Space Telescope have now successfully pinpointed a specific object that appears to be the source for a fast radio burst (FRB), extra-galactic short bursts of radio energy whose cause and origin have up-to-now been unexplained.

Blanchard and his team used a discovery of an FRB in a nearby galaxy made with the CHIME Outriggers array, a radio telescope in Canada, which was recently upgraded to enable FRB detections with precise positions. The researchers then turned to NASA’s James Webb Space Telescope to look for an infrared signal from the same location.

…The infrared data revealed an object, dubbed NIR-1, that is likely a red giant star or possibly a middle-aged massive star. A red giant is a Sun-like star near the end of its life that has expanded and brightened, while the other possibility is a star much more massive than the Sun.

Although these stars are unlikely to directly produce FRBs, the scientists say, they may have an unseen companion, such as a neutron star, pulling material away from the red giant or massive star. This process of transferring mass

The burst itself occurred on March 16, 2025 about 130 million light-years away in the galaxy NGC 4141. You can read the discovery paper here [pdf].

There remain of course great uncertainties. For one, NIR-1 is itself not likely the cause of the FRB, but related to its source in some manner. The scientists posit a number of explanations, from either an unseen magnetar (a pulsar with a powerful magnetic field), or a flare from this massive star reflecting off that unseen magnetar.

Regardless, this discovery helps narrow the theories considerably.

Slumping landslide in Mars’ glacier country

Overview map

Slumping landslide in Mars' glacier country
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was downloaded on July 1, 2025 from the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Labeled by the science team as a “flow,” it shows what appears to be a major collapse of the canyon’s south wall. The white dot on the overview map above marks the location, near the center of the 2,000-mile-long strip in the northern mid-latitudes of Mars that I label “glacier country” because almost every single high resolution image of this region shows glacial features.

This picture is no exception. First, the canyon appears filled with a glacial material, though its flow direction is unclear. Orbital elevation data suggests that this collapse is actually at the canyon’s high point, with the drainage going downhill to the east and west.

Second, the collapse itself doesn’t look like an avalanche of rocks and bedrock, but resembles more a mudslide. Since liquid water cannot exist in Mars’ thin atmosphere and cold climate, the soft nature of the slide suggests it is dirt and dust impregnated with ice. At some point, either because of the impacts that created the craters on its southern edge or because the sun warmed the ice causing it sublimate away thus weakening the ground structurally, the entire cliff wall slumped downward to the north.

The canyon itself is about 800 feet deep. It likely formed initially along a fault line, with ice acting over time to widen and extend it.

Avio gets 10-year lease from France to launch its Vega-C from French Guiana

9:44 am

The Italian rocket company Avio has now signed a 10-year lease with France to continue to launch its Vega-C from that nation’s French Guiana spaceport.

In a press release published on 19 August, the French Ministry of the Economy, Finance, and Industrial and Digital Sovereignty confirmed that, in line with the Seville agreement, Avio had been granted a ten-year licence.

…Avio will make use of the ELV launch complex at the Guiana Space Centre for the launch of its Vega C rockets. The pad was previously used for the original Vega rocket, which was officially retired in September 2024.

This deal is part of Europe’s move away from its centralized government-run Arianespace operations to the capitalism model. It has already shifted control of French Guiana from Arianespace back to France’s space agency CNES, which has begun to sign multiple similar deals with other European rocket startups. It is now in the process of shifting control of the Vega-C from Arianespace back to its builder, Avio, a shift that should be completed by the end of this year.

At that time, Avio will market the rocket commercially worldwide. Arianespace will no longer be a government middleman. This launchpad deal solidifies its access to a launch site, which it also plans to use for its next Vega upgrade, the Vega-E.

According to the head of India’s space agency ISRO, it is now targeting December 2025 for first unmanned test flight of its Gaganyaan manned capsule.

That flight will put the capsule into orbit for several days carrying a humanoid robot dubbed Vyomitra, designed to simulate what a human would experience in the capsule in space. It will be the first of three similar unmanned orbital test flights, leading up to a planned manned orbital mission in 2027.

Though this program has experienced numerous delays and program changes since it was first proposed in 2006, all the pieces have begun to fall into place in the past four years. It now appears that the above schedule is very solid. As long as there are no major test failures, India could launch its first astronauts by 2027.

Firefly studying feasibility of launching from northern Japanese spaceport

9:07 am

Japan's spaceports
Japan’s spaceports indicated by red dots.

Firefly and the commercial Japanese Hokkaido spaceport in the north of Japan have begun a feasibility study for launching Firefly’s Alpha rocket there.

Establishing an memorandum of understanding with the Hokkaido Spaceport means that the two entities can flesh out a more concrete launch complex design and figure out all of the logistics to bring Alpha launch capabilities to Japan.

In the past Hokkaido has been the location for a number of suborbital launches, but no orbital launches as yet. For example, the Japanese startup Interstellar used this site for its suborbital test flights in 2018, and hopes to use it for future orbital flights.

Firefly meanwhile has launched its Alpha rocket multiple times from Vandenberg in California. The company is also building a launchpad at Wallops Island in Virginia, and has signed a deal with the Esrange spaceport in Sweden. The Swedish launch site however is questionable because any orbital launch from there would have to cross over land of other countries, and so far it appears permission for such a thing has not been arranged. Firefly might therefore be looking at Hookaiddo for precisely this reason.

Russia today successfully launched a classified military payload comprising “multiple military spacecraft”, its Angara-1 rocket lifting off from its Plesetsk spaceport in northeast Russia.

This was Russia’s second launch in two days, something it rarely does any longer. It was also the fifth launch of this version of Russia’s new family of Angara rockets, using a modular design that can be configured for different size payloads. Launched into a polar orbit, the lower stages crashed in the ocean in the Arctic and Pacific.

The capsule will remain in orbit for about a month doing weightlessness and radiation experiments with a variety of biological samples, 1,500 fruit flies, and 75 mice. Though similar to the commercial capsules recently launched by Varda, Bion-M is different in that it appears the research has no marketability.

Spinlaunch raises $30 million for its Meridian broadband satellite constellation

Spinlaunch prototype launcher
The Spinlaunch prototype launcher

Spinlaunch, the startup that began by proposing launching payloads into space using a giant vertically oriented spinning centrifuge (as shown to the right), has now raised $30 million in private investment capital for its proposed Meridian broadband satellite constellation, designed to compete directly with Starlink and Kuiper.

The funding includes new investment from existing investors, including lead investor ATW Partners, as well as the previously announced strategic investment from Kongsberg Defence & Aerospace.

Kongsberg had previously invested $12 million, and is building 280 micro-satellites for this constellation.

It is very unclear from the press release when Spinlaunch will launch its first satellite, though it claims its “first customer link” will take place in second half of 2026. Considering the level of blarney the company exhibited in its initial spin-launch concept, we should remain very skeptical about its satellite constellation claims. Though the company has signed a deal to build a full scale spin launcher in Alaska, it increasingly appears it is shifting its effort from that to satellites.

Student suborbital rocket fails in first student attempt to reach space

10:09 am

The first rocket launch from Quebec and the first attempt by a student-built rocket to reach suborbital space unfortunately failed soon after lift-off on August 15, 2025 when the second stage separated prematurely.

The launch was part of a program by the rocketry division of a Canadian educational organization, Space Concordia.

While the launch appeared to start smoothly, it was approximately 23 seconds into the launch that the team reported that “vehicle split apart into 2 pieces.” Space Concordia said “the nosecone (came) tumbling to the ground” and that the airframe coasted “briefly before following suit.”

After the launch, and during the webcast, a representative said the “second stage separated early” and mentioned MaxQ, which is when the rocket will be under maximum aerodynamic pressure. Space Concordia said in a press release, “The team is continuing to review data to find the root cause of the anomaly.”

This student rocketry division has had some success over the years with smaller rockets, winning first prize in 2018 in the Intercollegiate Rocket Engineering Competition. This failure simply means it must try again. Either way, it appears it is training a new cadre of Canadian rocket engineers.

Note too that a similar student educational organization in Great Britain, Surrey Space, eventually upgraded its student-built cubesats into a profitable and very successful commercial cubesat manufacturing operation. It is very possible Space Concordia could do the same in Canada with rockets.

Psyche snaps picture of Earth-Moon system

Click for original image.

In a successful test of its cameras and pointing capabilities, the science team operating the probe Psyche — on its way to the asteroid Psyche — were able to snap a picture of Earth-Moon system from about 180 million miles away.

On July 20 and July 23, the spacecraft’s twin cameras captured multiple long-exposure (up to 10-second) pictures of the two bodies, which appear as dots sparkling with reflected sunlight amid a starfield in the constellation Aries.

One of those pictures is shown to the right. The scientists had previously taken similar calibration images of Jupiter and Mars.

To determine whether the imager’s performance is changing, scientists also compare data from the different tests. That way, when the spacecraft slips into orbit around Psyche, scientists can be sure that the instrument behaves as expected. “After this, we may look at Saturn or Vesta to help us continue to test the imagers,” said Jim Bell, the Psyche imager instrument lead at Arizona State University in Tempe. “We’re sort of collecting solar system ‘trading cards’ from these different bodies and running them through our calibration pipeline to make sure we’re getting the right answers.”

The spacecraft is scheduled to arrive at the metal asteroid Psyche in 2029, and will then spend at least two years flying in formation with it.

After being forced to change locations because of red tape and the refusal of the local aborigine authorities to sign an agreement, the Australian commercial spaceport startup Space Centre Australia has now obtained a land lease for its new location, dubbed Atakani, on the eastern shore of Cape York.

Space Centre Australia Pty Ltd (SCA) has secured a spaceport land lease, signing a multi-decade agreement with the local Traditional Landowners for approximately 300 km² at Billy’s Lagoon, Cape York. The agreement paves the way for the development of the Atakani Space Centre (ASC).

The Binding Term Sheet, signed with the support of Mokwiri RNTBC, marks the first time an Australian-based spaceport has secured a lease and opportunity of this scale. It ensures Traditional Owner access to country for cultural and ceremonial purposes, governance participation through the soon-to-be-established Luthiggi Corporation, and direct involvement in environmental management, cultural heritage monitoring, and operational activities. A royalty framework will deliver long-term economic benefits in addition to the spaceport’s operational revenue.

At the moment it appears the spaceport’s focus will be attracting suborbital launch companies, with the eventual goal to bring orbital rockets to the site.

China launches seven classified satellites

China today successfully placed seven satellites into orbit, its Kinetica-1 (or Lijian-1) rocket lifting off from its Jiuquan spaceport in northwest China.

No word on where the rocket’s lower stages crashed inside China. Its state-run press provided almost no information about the launch, except for trumpeting the fact that it lifted off from the launchpad at Jiuquan that China has built for its pseudo-commercial companies. The rocket itself however is built by pseudo-company CAS Space, which is simply a division created by the government-run Chinese Academy of Sciences.

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.
