Astronomers find another quasar in the early universe that really shouldn’t be there

9:28 am

The uncertainty of science: Using archival data from the WISE space telescope, astronomers have now identified another unexpected quasar in the early universe, only 850 million years after the Big Bang, that also flickers in several wavelengths.

The quasar’s flicker enabled the researchers to determine that, surprisingly, the ancient quasar’s whirlpool of gas and dust, known as an accretion disk, resembled a flat pancake, similar in shape to that of more modern-day quasars.

Their findings add to a longstanding mystery in cosmology: Why do supermassive black holes exist so early in the universe’s history? Physicists have assumed that a flat accretion disk reflects a relatively mature black hole that is in a calm and stable state. Black holes that are just starting to form, like those in the very early universe, should be more unsettled systems, with accretion disks that appear more puffy and chaotic.

The flat accretion disk around this very early quasar heightens the mystery of how supermassive black holes can grow and mature in a very short amount of cosmic time.

They estimate the quasar’s mass to be about 12 trillion suns. Its flickering, ranging about 20% in power, makes it the first such flickering quasar found this early in time. Such early quasars however are not unique. Astronomers have found about 200, all of which should not exist, based upon present Big Bang cosmology. There simply hasn’t been enough time for them to evolve, based on present theories of galactic formation.

Chinese pseudo-company Landspace launches two satellites

9:16 am

The Chinese pseudo-company Landspace yesterday successfully launched two satellites, its Zhuque-2E rocket lifting off from the Jiuquan spaceport in northwest China.

The Zhuque-2E is an upgraded version of Landspace’s Zhuquie-2 rocket, apparently using a larger fairing with an increased payload capacity. The two satellites were both for communications. One was for the Qianfan (Spacesail) internet constellation, which now has approximately 200 satellites in orbit out of a planned 12,000, with the constellation’s first phase targeting 648 by the end of the year. The second satellite was for a different constellation, and is a experimental satellite testing cell-to-satellite technology.

China’s state-run press provided no information about where the rocket’s lower stages crashed inside China.

The leaders in the 2026 launch race:

68 SpaceX
35 China
8 Russia
7 Rocket Lab

For the third straight year SpaceX leads the entire world combined in total launches, 68 to 60.

German rocket startup Isar raises $312 million; sets new launch date

9:06 am

Proposed or active spaceports in north Europe
Proposed or active spaceports in north Europe

The German rocket startup Isar Aerospace today announced in has raised $270 euros ($312 million) in a new funding round, bringing the total investment capital the company has raised to just under one billion, about $914 million.

The round is backed by new investors Island Green Capital and Molten Ventures with strong participation from existing investors HV Capital, Lakestar, UVC Partners with co-investor KfW Capital, and others, with substantial contributions from European stakeholders – underscoring Europe’s continued strong commitment to the company’s strategic role in providing space sovereignty and technological leadership.

This total does not include the funding provided by the European Space Agency, which is likely in the range of $20 to $40 million, though the actual number has not been published.

Isar's first launch attempt fails

The company also announced a new launch window for its second attempt to complete the first orbital mission of its Spectrum rocket. The new window runs from June 15 to 21, lifting off from Norway’s Andoya spaceport. The previous attempt failed less than a minute after launch. The company tried to do this second attempt in January, but scrubbed the launch several times due to technical issues.

If successful, this launch will make Isar the first new commercial rocket startup from Europe to complete a launch. Two others, PLD from Spain and Rocket Factory Augsburg from Germany, are saying they will launch this year, but no actual launch dates have been set.

All these new startups are small rockets, comparable to Rocket Lab’s Electron. Thus they will not compete with SpaceX initially. All however are aiming to move to larger versions as they gain experience and data.

The launch will also make Andoya the first commercial spaceport in Europe to successful complete an orbital launch.

Curiosity’s looks up Valle Grande to its future travels

10:19 am

Panorama, June 8, 2026
Click for high resolution. For original images go here, here, and here.

Overview map
Click for interactive map.

Cool image time! The panorama above was created by me using three pictures taken today by the left navigation camera on the Mars rover Curiosity (see here, here, and here).

The overview map to the right provides the context. The white dotted line indicates Curiosity’s actual travels, while the red dotted lines its planned route, both in the past and in the future. The blue dot marks its approximate position when these images were taken. The yellow lines indicate approximately the view.

The panorama looks up this spectacular valley, which the science team has named Valle Grande. The red dotted line on the panorama is my guess as to the rover’s future route. It will like not follow such a straight path, but weave back and forth as the science team directs it to look at interesting geological features along the way.

What remains unknown is the route the rover will take once it reaches those light-colored hills in the distance. The science team so far not indicated any chosen route through those hills. I suspect they want to get closer and do some on-site scouting before making any decision. The nature of that light terrain remains unknown. It could be easily traversed, or it could be a problem. From a distance it looks very soft, and thus it will likely required close inspection to make any definite plans.

SpaceX’s IPO: A quick look at the financial world’s present take

9:23 am

SpaceX logo

As SpaceX and the Wall Street gear up for the June 12, 2026 initial public offering (IPO) of SpaceX stock, there have been a number of articles published in the past week expressing skepticism about it, mostly aimed at trying to predict what will happen in order to advise potential buyers.

Much of this is guesswork, but the people speaking are people who do this for a living, so it might be worthwhile to take a look at what what they have to say. Below are a few examples.

First, the New Yorker published a detailed article questioning the overall $1.75 trillion valuation of SpaceX listed in its IPO. It doubts the reality of the company’s AI division, its plan to launch a constellation of data satellites, and notes that Starlink and the launch divisions don’t make up the difference. Overall, its analysis concludes the valuation is over-rated, and should be approached with caution.

Business Insider also posted an article expressing reservations about the IPO’s unusual requirement that 30% of all shares be reserved for the retail market, made up of small individual buyers.

Here’s how it’s instead been interpreted by the retail-investor commentariat: They’re capitalizing on trader excitement and relying on it to supplement demand from institutions. The heavy allocation is essentially setting up retail to hold the bag after longer-term shareholders take profits.

I myself have had this analysis confirmed by one source, that the major big stock buyers are themselves planning to hold back their purchases for at least the first few months, believing the stock price will be pumped up initially by this flood of small enthusiastic buyers. They will wait for it to drop — as they expect — and then buy, taking their profits then.

Meanwhile, the Wall Street Journal posted two articles with contradictory conclusions:

The first article is very optimistic. The second is less so, approaching the situation more carefully.

For my readers who wish to invest, I strongly suggest you read them all, and consider them all. Investment here might not be as great as you think.

For SpaceX and the future of space exploration however the situation is excellent, whether or not buyers are going to make money on its IPO. The company is certain to bring in more than $75 billion, maybe as much as $86 billion, giving it the capital to do everything it wants in the next few years. It will build Starship. It will send it to both the Moon and Mars. It will have the resources to fuel Elon Musk’s fundamental dream, building a major human civilization throughout the solar system.

In this alone the IPO will be historic, as it lays the groundwork for the human colonization of space. History begins now, and it does so under the aegis of capitalism and freedom.

Czech Republic buys seat on Vast mission to ISS

8:37 am

In its continuing effort to sign customers (and earn income) outside of NASA funding, the space station startup Vast today announced it has signed a deal with the Czech Republic to fly one of its astronauts to ISS on its planned mission there in 2027.

This agreement builds on the memorandum of understanding that Vast, and the Czech Republic signed in 2024. Subject to Multilateral Crew Operations Panel (MCOP) review and approval, Aleš Svoboda, one of the 12 members of the astronaut reserve selected by ESA in November 2022, will serve as the mission pilot. The MCOP’s decisions are reached through a consensus among representatives from all five space station partners: NASA, ESA, Roscosmos, the Japan Aerospace Exploration Agency, and the Canadian Space Agency. Pending approval, Aleš Svoboda will become the first Czech astronaut to visit the International Space Station. Svoboda is planned to join ESA Astronaut Thomas Pesquet who is the named Commander for the mission.

Pesquet is a French astronaut flying under the deal France signed with Vast only two weeks ago.

Unlike the Starlab and Axiom stations, Vast is building its single module demo station, Haven-1, with no government funds. It is not only flying this private two-week mission to ISS, it is also planning four two-week missions to Haven-1 during if three year mission, once it launches next year. All will use SpaceX’s Falcon 9 as a launch provider, with one of its Dragon capsules for crew transport.

SpaceX launches 29 Starlink satellites, uses 1st stage for record 35th time

3:37 am

SpaceX early this morning successfully launched another 29 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral Space Force station in Florida.

The first stage (B1067) successfully completed its 35th flight (70 days after its previous flight), landing on a drone ship in the Atlantic. This flight was a new record for the reuse of a Falcon 9 first stage, placing it only four behind the space shuttle Discovery in the rankings for the most reused launch vehicle:

39 Discovery space shuttle
35 Falcon 9 booster B1067
33 Atlantis space shuttle
33 Falcon 9 booster B1071
32 Falcon 9 booster B1063
31 Falcon 9 booster B1069
28 Columbia space shuttle
28 Falcon 9 booster B1077
28 Falcon 9 booster B1078

Sources here and here.

Expect these rankings to see some newer Falcon 9 first stages in the near future The older stages listed here seem to take about two months generally to turn-around after each launch. The younger stages are instead turning around much faster, in one month or less.

The leaders in the 2026 launch race:

68 SpaceX
34 China
8 Russia
7 Rocket Lab

For the third straight year SpaceX leads the entire world combined in total launches, 68 to 59.

NASA’s X-59 completes first no-boom supersonic flight, more than a year after a private company did it

10:28 am

NASA yesterday made a big deal about the first successful supersonic test flight of its X-59 test plane, built by Lockheed Martin for $247.5 million to demonstrate quiet no-boom supersonic flight.

And as usual, our uneducated propaganda press played along, touting the wonders of this new NASA achievement. A few examples:

Poppycock. Not one of these news articles made mention of the fact that the private commercial company Boom Supersonic accomplished the same feat eighteen months earlier, its XB-1 supersonic airplane breaking the sound barrier with no boom three separate times. And it did so using private funds for significantly less and getting the job done faster and in a manner that it can quickly convert into its planned commercial supersonic planes.

The X-59 is a typical NASA test project, designed to test a technology in a manner that is generally too specific and expensive for commercial use. Without doubt the engineering and the data from these flights will be helpful to companies like Boom, but to use it will require major changes and revisions to bring the cost down. It is for this reason Boom did its own engineering and test.

That I appear to be the only news outlet aware of this important background information — that puts a significantly different light on this government project — illustrates the bankruptcy of our modern media. They don’t know anything, and can only rewrite press releases.

Australia’s Southern Launch range gets another re-entry capsule customer

9:44 am

Proposed Australian spaceports
Australian spaceports: operating (red dot) and proposed (red “X”)
Click for original image.

The Australlian spaceport Southern Launch, which also controls the Koonibba Test Range where a variety of government and commercial capsules have landed since 2020, has signed another American company building its own re-entry capsules.

Southern Launch has signed a new agreement with US-based SpaceWorks Enterprises, Inc. to host multiple re-entry missions at the Koonibba Test Range in South Australia.

The agreement enables SpaceWorks to advance its growing portfolio of atmospheric Re-Entry Devices (RED) and further demonstrates confidence in the Koonibba Test Range as the leading global location for the safe and reliable return of spacecraft and high-value payloads.

This is the third American re-entry capsule company to sign with Southern Launch. Varda has already landed I think five capsules at Koonibba, and has a deal to land up to 20 through 2028. In 2025 the American startup Lux Aeterna signed a deal as well.

Two take-aways from this story: First, SpaceWorks as a re-entry capsule company appears to be a new project, joining the host of other re-entry capsule companies that have obtained investment capital since Varda demonstrated its success, including three U.S. and five European startups. It really appears the financial community sees profits here, and are committing money to this effort.

Two, the red tape by multiple U.S. government agencies in 2023 that delayed the return of Varda’s first capsule to the Air Force’s test range in Utah for six months has driven all this business out of the U.S.

That red tape was part of the Biden administration’s general policy aimed at hindering private enterprise, but it also is systematic to the existing administrative state that dominates and impedes American industry across the board. The result here is the business went elsewhere.

NASA clarifies air leak situation yesterday on ISS

8:27 am

Figure 3 from September Inspector General report
Figure 3 from September 2024 Inspector General report, showing Zvezda’s location on ISS, as well as the station’s leak rate at that time.

According to a NASA update posted late yesterday, the agency had cause to order its astronauts to shelter in place within their Dragon capsule due to planned repair work proposed by the Russians.

The week of June 1, during Progress 95 spacecraft cargo operations, Roscosmos noted an increase of the previous leak rate to two pounds per day and identified new suspected leak areas in the PrK. Following this observation, Roscosmos made the decision to begin work toward a more extensive inspection and structural repair effort Friday morning. This revised approach involved cutting a bracket to better access an area identified as a possible leak source for further inspection, using a method that could have resulted in elevated risk to the structure in the area. In response, NASA directed the four SpaceX Crew-12 members and NASA astronaut Chris Williams, who flew to station aboard the Soyuz MS-28 spacecraft, to take a heightened safety posture, known as a safe haven, inside the SpaceX Dragon spacecraft during the procedure.

Later Friday morning, Roscosmos paused and did not perform the structural repair work in favor of conducting additional measurements and data assessments, which included inspection of suspected areas of interest and review of areas where sealant was previously applied. NASA strongly supported that decision, and as a result, following that decision, Crew-12 and Williams ended their safe haven activities and returned to normal operations aboard the orbiting laboratory.

In other words, the leak rate had increased to match the high rates seen from 2019 to 2025, and the Russians were planning work that threatened the structure of the module. It appears NASA objected, and eventually the Russians acceded to those objections.

What happens next however remains unclear. If the leak rate has suddenly jumped from one pound per day to two pounds a day, that suggests the situation is worsening, and doing so at an alarming rate. As this new leak occurred shortly after a Progress freighter docked at Zvezda, it suggested the docking instigated it. It also suggests any further dockings there are likely to worsen the situation even more.

FCC grants waiver to Amazon Leo constellation, despite its failure to launch on time

8:07 am

Amazon Leo logo

The Federal Communications Commission (FCC) yesterday granted [pdf] a license waiver to Amazon, allowing it to continue deploying its Leo constellation even though the company will fail to meet its license requirement to get half its constellation (1,616 satellites) into orbit by July 2026.

While granting the waiver, the FCC also made it clear Amazon still needs to meet the license’s deadline for full deployment of all 3,232 satellites by July 30, 2029.

In the event Amazon Leo fails to satisfy the final milestone on July 30, 2029, this will result in reduction of the total number of Amazon Leo’s authorized satellites to the total number of satellites that are operational on that date.

In other words, the Leo constellation will be truncated if Amazon fails to get the full constellation up on time.

To further encourage Amazon to meet future deadlines, the FCC also stated that the satellites of Amazon’s first-half constellation that are launched late — after the July 2026 deadline — will lose certain spectrum rights for the next 20 months, “or until 50% of the constellation is launched and operational, whichever occurs first.” This order is expressly designed to encourage the company to accelerate its launch pace.

Finally, the FCC declared that Amazon will forfeit its surety bond for not meeting its July 30, 2026 launch obligation.

Launching almost 3,000 satellites in the next three years is still going to be challenging. Right now Amazon is dependent mostly on two grounded and as yet unproven rockets (Vulcan and New Glenn) and a third (Ariane-6) that cannot launch at a very quick pace for at least another two years. And its additional a ten-launch contract with SpaceX won’t be sufficient to get the entire constellation in orbit on time.

In other words, unless Vulcan and New Glenn get fixed quickly and resume launches, Amazon is going to have trouble meeting the FCC’s final deadline.

Charles Laughton – The Gettysburg Address

6:01 pm

An evening pause: A scene from the 1935 film, Ruggles of Red Gap. In the film he plays a British butler who has been won by a rich western family in a poker game. He comes to America, and is infected by its freedom.

I posted this back in 2011, on the anniversary of Lincoln’s first presentation. Time to play it again, since so many Americans today — like the cowboys in the movie — don’t have a clue what Lincoln said.

Enjoy your weekends!

NASA admits mismanagement and human errors caused 2025 Goldstone antenna damage

4:53 pm

NASA today released its completed investigation into the November 2025 incident that severely damaged its Goldstone antenna in California when workers allowed the antenna to “over rotate” beyond its acceptable limits, putting it out of commission.

In its final report, the board found the mishap primarily stemmed from software weaknesses, human error, and an undetected failure in the antenna’s hydraulic limit system. Investigators determined an electrical issue at the antenna the previous day caused the control system to misreport the antenna’s rotation state, an issue that went unnoticed and triggered multiple limit-stops during the Juno track on Sept. 16. While working to identify the limit-stop problem, operators performed several troubleshooting steps that inadvertently bypassed software and hardware safeguards, which ultimately led to the over-rotation incident. After flooding in the antenna base was observed, operators attempted to stow the antenna as a safety precaution, however, because the system had already passed the rotation limits, this action drove the antenna further into over‑rotation, causing additional damage.

Additionally, the investigation found the antenna’s hydraulic limit system, its final mechanical safeguard, was inoperable on Sept. 16 after being damaged in an undocumented prior incident. The system also had not been adequately tested for an undetermined period of time.

Investigators also concluded workplace culture pressured operators to work as expeditiously as possible, often stretching beyond their usual roles, expertise, and training, to keep the antenna operating. The board states the cultural conditions observed at Goldstone were not present at the network’s other sites, where roles and responsibilities are followed more consistently. Other contributing factors outlined in the report include inadequate procedures, reliance on undocumented practices and tacit knowledge, and gaps in the antenna’s control logic. [emphasis mine]

You can read that report here [pdf], but be warned that large sections are redacted, apparently in an effort to protect the identities of those responsible.

Nonetheless, it is very clear from the highlighted text above that the management and work situation at Goldstone was a mess, and that the mishap was caused not by faulty engineering but by faulty work practices and bad management. Unfortunately, nowhere in the report is it said that there will be any management changes. This fact might have been redacted, but I suspect not. It is typical of government agencies like NASA after incidents like this to whitewash the investigation, concluding simply that “we should have done better and we now we will!”

The repairs will cost NASA about $4.6 million, and will likely not be completed until 2028.

Musk’s answer when asked, “Why SpaceX going public now?”

11:02 am

In a JP Morgan public interview today about SpaceX’s upcoming initial public offering (IPO), Elon Musk was asked why the company was going public now, and gave a somewhat long-winded answer that included talking about the Sun as a major source of energy in the future, and then concluded very simply, to laughter: “We are embarking on a massive new growth phase and we need capital for that.”

I have embedded his response below. It is worthwhile watching because he does indicate much of what SpaceX wants to do, which not only involves an additional 100,000 communications satellites as well as a constellation of data satellites, it might also include possible solar power generation for use back on Earth. He also notes the company has been self-funding now for almost a decade.

China completes two more launches

9:55 am

Since yesterday China has successfully completed two launches from two different spaceports using two different types of rockets, with both launches placing more satellites in orbit for its Qiafan (SpaceSail) internet constellation.

First China yesterday placed 18 Qianfan satellites in a polar orbit, its Long March 6B rocket lifting off from its Taiyuan spaceport in northeast China. The state-run press provided no information as to where the rocket’s lower stages (using very toxic hypergolic fuels) crashed.

Next, China today placed another batch Qianfan satellites into orbit, its Long March 8 rocket lifting off from its coastal Wenchang spaceport. Though the state-run press did not specify the number of satellites on this launch, based on past launches the total was likely 18 also.

The constellation presently has roughly 200 Qianfan satellites in orbit, out of a planned constellation of as many as 12,000. The first phase of the constellation however only requires 648, which China hopes to reach before the end of the year.

The leaders in the 2026 launch race:

66 SpaceX
34 China
8 Russia
7 Rocket Lab

For the third straight year SpaceX leads the entire world combined in total launches, 66 to 59.
