Japanese government proposes 300-mile-long conveyor belt for moving packages

12:27 pm

Pork to the max! A supposedly “expert panel” in Japanese government’s Land, Infrastructure, Transport and Tourism Ministry has proposed building a 300-mile-long conveyor belt — possibly underground in a tunnel — between the cities of Tokyo and Osaka for moving packages, to be completed by 2034.

The biggest challenge is cost. According to a survey of construction companies, the cost of building an underground tunnel ranges from ¥7 billion to ¥80 billion per 10 kilometers, so a system linking Tokyo and Osaka would cost up to ¥3.7 trillion. When the ministry in the year 2000 first planned logistics links above ground, it estimated construction costs of ¥25.4 billion per 10 kilometers.

In dollars, the total cost of ¥3.7 trillion equals about $23 billion.

The so-called goal would be to eliminate 25,000 trucks, supposedly saving the world from those evil fossil fuels. That the belt would have to be powered of course is not mentioned, which I bet would probably require burning about the same amount of fuel.

The panel also claimed the conveyor belt would save money and reduce labor needs because it would also eliminate 25,000 truck drivers. With Japan facing a crash in population, the panel claims a shortage of labor is expected in the coming decades, and this plan will supposedly solve that. That’s also a fantasy. Who would upload the pallets onto the belt? Who would offload them? And how would those pallets be delivered at each point? And what about maintaining this giant conveyor belt? In the end, this plan will do nothing to reduce labor needs.

Nor is such a plan really necessary. When the population drops, the amount of cargo will drop as well. There will be no labor shortage in the shipping industry.

All this plan does is create a gigantic public works project that will almost certainly go over budget, fail to meet its schedule, and increase the cost of goods for both the companies and the public. But boy, it sure is going to employ a lot of government workers to supervise construction and operations!

Note I found about this project through a report at New Atlas, which as a left-leaning techno website accepted the plan instantly as brilliant and awe-inspiring.

Firefly signs deal to launch its Alpha rocket from Esrange spaceport in Sweden

9:43 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

Firefly has now signed a deal to launch its Alpha rocket in 2026 from the Esrange spaceport in Sweden, becoming that spaceport’s second orbital customer.

Esrange is not really a new spaceport. It was originally built in the 1960s and was used for decades for suborbital test launches, much like Wallops Island in the U.S. In January 2023 it upgraded one launchpad to allow commercial orbital launches, and in May 2024, signed a launch deal with a new rocket startup from South Korea named Perigee.

This new contract with Firefly is a bigger deal, because Firefly has already launched several times, and is more established.

These developments indicate as well the cost of red tape in the United Kingdom. The map to the right shows the spaceports competing for business in Europe. The two UK spaceports (Saxaford and Sutherland) began construction years before Esrange decided to upgrade, but both are now losing business to Sweden because regulatory delays at the Civil Aviation Authority in the UK has delayed all launches there for years.

Arianespace calls for Europe to require all European space payloads use European rockets

9:57 am

Arianespace, whose many-decade-long European launch monopoly is presently threatened by a wave of new rocket startups and an effort by European governments to created a competitive launch industry of many companies, has now urged Europe to require that all European space payloads use European rockets.

Arianespace head of public affairs Charlotte Lang has advocated for legislation that would require European missions to be launched aboard European rockets. Lang made the comments during the “Ensuring Long Term Autonomous Access to Space for Europe” panel on the first day of The European Space Forum conference. “The EU should enforce the principle of European launcher preference,” said Lang.

In a follow-up statement, Arianespace reiterated “the need for the EU to legislate that European missions are launched from European territory using launchers and technology manufactured in Europe by European providers.” The company identified the European Union’s planned IRIS² constellation as the “perfect opportunity to advance this initiative.”

Arianespace is like Blue Origin. It can’t get its rockets built and flying at a competitive price, so instead it advocates lawfare to limit competition in order to give it a favored position when it bids on future launch contracts.

In the case of Europe, I think this Arianespace effort will generally fall on deaf ears. The trend among numerous European governments (Germany, France, Italy) is to encourage new rocket companies to compete with Arianespace, in order to create options. These governments will of course wish to favor these new European rocket companies with any contract awards, but they will also not want to tie their hands with the kind of legislation Arianespace proposes. They all discovered in the past two years what could happen if they do that, when Arianespace failed to get Ariane-6 launched on time, and Europe ended up with no launch capabilities. During that time period they still had the option to use other non-European options (such as SpaceX). Having that flexibility in the future makes great sense.

Blue Origin to FAA: Limit future SpaceX Starship launches at Cape Canaveral

9:38 am

Blue Origin has once again decided to use lawfare against SpaceX rather than actually build rockets that are competitive. As part of the process by the FAA to do a new Environmental Impact Statement on SpaceX’s plans for Starship/Superheavy launches at Cape Canaveral, Blue Origin last week submitted its own comment asking the FAA to cap the launches of its competitor, citing environment concerns.

The company recommends the following mitigation method for SpaceX’s Starship launches, prior to the company being issued a Vehicle Operator License:

“Capping the rate of Ss-SH launch, landing, and other operations, including but not limited to test firings, transport operations, and fueling, to a number that has a minimal impact on the local environment, locally operating personnel, and the local community, in consideration of all risks and impacts, including but not limited to anomaly risks, air toxin and hazardous materials dispersion, road closures, and heat and noise generation.”

Along with requesting a max number of Starship launches at the site, Blue Origin argues that the government increase launch infrastructure that opens other launchpads to nearby lessees when roads are forced to be closed for SpaceX launches. The filing also notes that SpaceX has already received environmental testing at its Starbase site in Boca Chica, Texas.

You can read Blue Origin’s full comment here [pdf]. Essentially, Blue Origin is attempting to use this new impact statement to have the federal government damage or destroy its competition.

Musk’s response was a two word tweet: “Sue Origin.”

It is very clear that Jeff Bezos’s company is poorly focused. In the last decade it has built almost nothing, while spending a lot of time filing lawsuits against its competition. This action is simply another example.

Worse, Blue Origin’s comment will provide ammunition for the continuing Biden administration lawfare against Musk and SpaceX, making it difficult for the FAA to approve the impact statement as requested by SpaceX. If so, the development and operational use of Starship/Superheavy will be seriously threatened.

More garbage science about wildfires and global warming from Nature

12:31 pm

Nature: the science journal that no longer does real science
The science journal which no longer
understands how real science is done

The once highly respected science journal Nature continues its descent into propaganda and bad science, all because it bows unskeptically before the altar of global warming and leftist science fantasies.

Today’s example is an article this week entitled “You’re not imagining it: extreme wildfires are now more common,” describing a new Nature paper that attempted to use satellite data to prove that the intensity of wildfires has increased in the past two decades.

For the current study, published in Nature Ecology and Evolution on 24 June, Cunningham and his colleagues scoured global satellite data for fire activity. They used infrared records to measure the energy intensity of nearly 31 million daily fire events over two decades, focusing on the most extreme ones — roughly 2,900 events. The researchers calculated that there was a 2.2-fold increase in the frequency of extreme events globally in 2003–23, and a 2.3-fold boost in the average intensity of the top 20 most intense fires each year.

We’re all gonna die! As is usual for these crap climate-related studies, the entire goal is to drum up some manufactured new crisis that justifies the claim that the climate is warming. This study is no different, as the article eagerly notes:

Although the study doesn’t directly connect the fire trend to global warming, Cunningham [the study’s lead author] says “there’s almost certainly a significant signal of climate change”. Research has shown that rising temperatures are drying out ecosystems — such as coniferous forests — that are naturally prone to fire. This provides fuel that can boost the fires’ size and longevity. The latest study also found that the energy intensity of the fires increased faster during the night-time over the past two decades than during the daytime, which aligns with evidence4 that rising night-time temperatures are contributing to fire risk.

Not surprisingly, the New York Times immediately jumped on the bandwagon with its own article that accepts the conclusions of this research with utter naivety.

What junk. First, Cunningham fails to note this minor fact mentioned in the abstract of his own paper:

Reparations: Taking money from people who never owned slaves and giving it to people who never were slaves

12:48 pm

Harvard: where you get can get a shoddy education centered on hate and bigotry
Harvard: where you can spend a lot of money
getting a shoddy education teaching hate and bigotry

The effort to justify the new fad of forcing all Americans today to pay blacks reparations for the evil of slavery that was eliminated a century and a half ago at the cost of more than 600K lives continues. A recent published study by two “Didn’t Earn It” (DEI) academic elites at the Harvard Kennedy School attempts to justify the distribution of reparations now by claiming that the U.S. has a long history of paying out money to harmed individuals. From the paper’s abstract:

[T]he United States has a long-standing social norm that if an individual or community has suffered a harm, it is considered right for the federal government to provide some measure of what we term “reparatory compensation.” In discussing this norm and its implications for Black American reparations, we first describe the scale, categories, and interlocking and compounding effects of discriminatory harms by introducing a taxonomy of illustrative racial harms from slavery to the present. We then reveal how the social norm, precedent, and federal programs operate to provide victims with reparatory compensation, reviewing federal programs that offer compensation, such as environmental disasters, market failures, and vaccine injuries. We conclude that the government already has the norm, precedent, expertise, and resources to provide reparations to Black Americans. [emphasis mine]

The highlighted word is key to understanding the fundamental intellectual dishonesty of these incompetent Harvard academics. In their paper they use numerous examples of cases where the government has provided compensation to actual individuals — such as veterans, individuals harmed by radiation from nuclear tests, and those who lost their pensions due to bankruptcy or mismanagement of their pension funds — and then claim this proves paying reparations to the community of blacks, based merely on their race and the past existence of slavery, is within traditional American jurisprudence.

This is all a lie. » Read more

Emerson College in Boston leads the way in supporting Hamas and losing enrollment

12:52 pm

Emerson College: Where only leftist pro-Hamas speech allowed
Emerson College: Where only
leftist pro-Hamas speech is allowed

This week Emerson College in Boston announced that, because of a significant and unexpected drop in enrollment for the coming year, it is going to have to lay off staff as well as not fill a number of vacant positions.

In an email to college’s faculty and staff, the college’s president Jay Bernhardt obliquely mentioned what could be the main cause of this lack of new students:

We attribute this reduction to multiple factors, including national enrollment trends away from smaller private institutions, an enrollment deposit delay in response to the new FAFSA rollout, student protests targeting our yield events and campus tours, and negative press and social media generated from the demonstrations and arrests, [emphasis mine]

To put Bernhardt’s oblique comments into clarity, Emerson was hit in April with a gigantic pro-Hamas occupation that took over a local public right-of-way. The university’s response to this take-over was, to put it mildly, very supportive of the mob, even after the police moved in to clear the road and arrested 118. Here is what Bernhardt wrote to the Emerson community after those arrests:

Italy approves new space law

9:40 am

Italy’s Council of Ministers yesterday approved language for a new space law and five year space economic plan, designed to regulate the commercial space operations inside Italy as well by Italian companies operating in foreign lands.

In addition to mandating authorization for national and foreign operators who intend to conduct space activities from Italian soil, the law will also regulate the activities of national operators intending to conduct business from foreign territories. One element of regulatory compliance outlined within the law addresses the management of space incidents. Operators will be required to secure insurance coverage of up to €100 million per incident. There are, however, provisions allowing for the potential for lower caps in cases of reduced risk.

More details about the law can be found here. It gives regulatory authority to Italy’s space agency ASI, while also establishing a five-year government program (funding not disclosed) to stimulate the space sector.

The released details are insufficient to find out the real consequences of this law. If written correctly, the regulations could actually make it easier for the private sector to prosper. If not, it could instead squelch new startups as well as existing companies.

Japan’s space agency reveals it was hacked in 2023

9:02 am

Japan’s space agency JAXA today revealed that beginning in 2023 and periodically into this year it has been attacked repeatedly by hackers, with data from more than 10,000 files stolen.

Attacks occurred in June 2023 and multiple times a year, although investigations are ongoing regarding whether more information was stolen in this year’s attacks.

In addition to internal data, potentially compromised entities include NASA, Toyota Motor Corp., Mitsubishi Heavy Industries Ltd. and the Defense Ministry, with which JAXA has nondisclosure agreements. Information from numerous aerospace and defense-related organizations and companies was also exposed.

JAXA stated that no sensitive information related to national security or rocket technologies was stolen in last year’s breach. Personal data of approximately 5,000 JAXA personnel and employees from partner companies was used to access the Microsoft 365 accounts of JAXA executives.

It appears JAXA officials only found out about the attack when police told them about it months after the June 2023 attack. Agency officials now say no sensitive rocket or satellite data was stolen. Instead, it appears the attack targeted personal communications as well as research facilities.

The report provided no indication about the source of these attacks, but noted that a 2016 attack is known to have come from China.

The intellectual dishonesty of Democrats proven once again

12:43 pm

Democrat Neil Baron, either very lazy or a enthused slanderer
Democrat Neil Baron, either very lazy
or a enthused slanderer

The Cleveland Plain Dealer was forced on June 18, 2024 to retract entirely a June 9th op-ed written by Democrat lawyer and political consultant Neil Baron when it was threatened with slander and libel lawsuits from three FBI whistleblowers because of the blatent false accusations Baron included in this op-ed.

Baron’s op-ed, which can still read here, was mostly a partisan attack on Congressman Jim Jordan (R-Ohio) and his effort to expose the FBI’s non-stop abuse of power. In doing so, however, Baron accused three FBI whistle-blowers of doing things they did not do.

George Hill, advocated dismantling the FBI, claiming it’s better to “die than to have domestic intelligence.” Another, Garret O’Boyle, said Jan. 6 was a “set up” by Democrats and the FBI. He posted a video of himself at the Capitol sporting body armor, a gas mask and an AR-15 rifle. A third, Marcus Allen, assaulted several Capitol Police on Jan. 6, and claimed the insurrection was a government scheme.

As noted in the newspaper’s apology and retraction it admitted Baron’s accusations were simply false.

Allen was not a participant in the Jan. 6 insurrection in Washington D.C. and has never been accused of assaulting Capitol Police officers during the insurrection. O’Boyle did not claim the insurrection was set up by Democrats or post video of himself at the Capitol wearing body armor, a gas mask and an AR-15 rifle. While George Hill has been critical of his former employer, he did not make a quote attributed to him in the column or advocate for dismantling the FBI.

In other words, Baron was making these accusations up, and the newspaper did no fact-checking prior to publication, accepting those bald-faced lies without question. » Read more

Pro-Hamas lefty arrested for several arson attacks on UC-Berkeley campus

Casey Goonan, a pro-Hamas activist arrested for arson
Casey Goonan, a pro-Hamas activist
arrested for arson

If you want to know the mentality of the pro-Hamas movement across America and largely centered on many “elite” campuses, you need only look at the story of Casey Goonan. Goonan is a 34-year-old long time leftist activist who was previously arrested in September 2023 for “felony vandalism & resisting arrest” (he had used a hammer to destroy the sign of a hotel at the protest site).

He has now been arrested again as the prime suspect in a series of four arson attacks on the UC-Berkeley campus in the past three weeks.

On Monday evening [June 17], Cal Fire announced the arrest of 34-year-old Casey Robert Goonan “in connection with the firebombing attack of a UC Berkeley Police Department vehicle and three other arson attacks on UC Berkeley campus during the month of June.”

Goonan was arrested Monday “following a comprehensive investigation” by Cal Fire’s Office of the State Fire Marshal Arson and Bomb Unit, UC Berkeley police, the FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives. Goonan is now facing multiple felony charges, authorities said, including “the possession and use of destructive devices and multiple counts of arson.” He is in custody at Santa Rita Jail with a bail of $1 million, according to Monday’s statement.

In all these arson attacks, the firebomber (allegedly Goonan) released anonymous statements claiming credit. The first such statement, proudly admitted to firebombing a UC-Berkeley police vehicle and concluded as follows:

Slovenia becomes 23rd member nation of the European Space Agency

9:05 am

Formerly part of Yugoslavia and largely aligned with the communist bloc during the Cold War, Slovenia has now signed on to become the 23rd member nation of the European Space Agency (ESA).

Slovenia has been working with ESA since 2008, when it signed a first Cooperation Agreement, followed by a European Cooperation Agreement. This cooperation was strengthened with its accession to associate membership in 2016, which it upgraded in 2020 with a new Agreement for an enhanced Association. This included a provision that after its expiration in 2025, Slovenia can apply for ESA membership.

Slovenia’s membership still needs to be ratified, but that is expected.

Increasingly Putin’s invasion of the Ukraine has proven to be incredibly stupid. It has not only trapped Russia in a quagmire that it can’t easily escape, with victory nowhere in sight, it has caused all of its other neighbors to look west, away from Russia, out of fear of getting invaded themselves. Slovenia is just the most recent example.

Kansas sues Pfizer for lying about the safety and effectiveness of its COVID jab

1:13 pm

Apparently a company of liars
Apparently a company of liars

The state of Kansas yesterday filed a detailed suit against the pharmaceutical company Pfizer over the many lies and misrepresentations it pushed as it rolled out its COVID jab, such as hiding the actual documented “adverse events”, including many deaths, that occurred after people got jabbed.

You can read the complaint here [pdf]. It opens as follows;

Pfizer misled the public that it had a “safe and effective” COVID-19 vaccine.

  • Pfizer said its COVID-19 vaccine was safe even though it knew its COVID-19 vaccine was connected to serious adverse events, including myocarditis and pericarditis, failed pregnancies, and deaths. Pfizer concealed this critical safety information from the public.
  • Pfizer said its COVID-19 vaccine was effective even though it knew its COVID-19 vaccine waned over time and did not protect against COVID-19 variants. Pfizer concealed this critical effectiveness information from the public.
  • Pfizer said its COVID-19 vaccine would prevent transmission of COVID-19 even though it knew it never studied the effect of its vaccine on transmission of COVID-19.
  • To keep the public from learning the truth, Pfizer worked to censor speech on social media that questioned Pfizer’s claims about its COVID-19 vaccine.

The lawsuit has lots of juicy factoids. For example, Pfizer kept its own database of adverse events after people took its jab, and lied about that data to the public.

Just remember: These obnoxious disturbers of the peace are all Democrats

12:46 pm

They’re coming for you next: In what is actually a relatively mild example of the obnoxious and almost always illegal protests by pro-Hamas supporters — such as taking over and trashing buildings, attacking Jews and blind children, and blocking traffic — for the past six months protesters have been disturbing the peace at late evening and early morning hours in the residential neighborhood where senator Ted Cruz (R-Texas) lives with his family in Houston.

For the past 6 months, anti-Israel protestors have come to my home just about every Sat morning at 7 am and most Fri nights until 10 or 11 pm. They scream, disturb the peace & wake the neighbors.

I have embedded below the video of these protesters that Cruz included with his tweet:

German rocket startup looking for alternatives to Saxavord spaceport

9:13 am

Australian commercial spaceports
Australia’s commercial spaceports. Click for original map.

Because of regulatory delays at the Saxaford spaceport in Great Britain, the German rocket startup Hyimpulse has signed a launch deal with the Australian commercial spaceport Southern Launch.

In May, HyImpulse launched the inaugural flight of its suborbital SR75 rocket from the Southern Launch Koonibba Test Range. The flight had initially been expected to be launched from SaxaVord in Scotland, but delays in the construction of the facility forced the company to look elsewhere for a host.

On 6 June, Southern Launch announced that it had signed a Memorandum of Understanding with HyImpulse for the launch of additional SR75 missions from Koonibba. The agreement also included provisions for the pair to explore the possibility of launching orbital flights aboard the HyImpulse SL1 rocket from Whalers Way Orbital Launch Complex on the south coast of Australia.

According to Hyimpulse’s November 2023 deal with Saxaford, it was to have flown two suborbital flights of the SR75 in 2024 and one orbital flight of SL1 in 2025.

It could very well be that SL1’s first orbital test launch will still take place from Saxavord, but the several years of delays caused by the red tape from the UK’s Civil Aviation Authority in approving Saxavord has forced its customers to seek alternatives. Hyimpulse for example now has agreements not only with Southern Launch in Australia. The French space agency CNES has approved it to launch from French Guiana as well.

In addition, the German rocket startup Isar Aerospace in November 2023 signed a deal with the new Andoya commercial spaceport in Norway. Andoya had come into this spaceport competition very late, but it apparently won this deal because Isar saw the regulatory problems in the UK and decided to look elsewhere.

Jimmy Heyward, blacklisted for touting American patriotism
Jimmy Heyward, blacklisted for extolling
American patriotism

They’re coming for you next: When 13-year-old Jimmy Heyward decided to run for the position of “commissioner of spirit and patriotism” at St. Bonaventure Catholic middle school in Huntington Beach, California, he wrote a campaign speech that not only extolled the idea of patriotism, but wittily mimicked Donald Trump’s own campaign slogans. His conclusion:

So accordingly, I Jimmy Heyward, am running for Commissioner of Patriotism and School Spirit. I want to clarify that my ideas are not promises, but I can promise to make pep rallies great again! … I will make the school spirit great again! I will make patriotism within SBS great again! And most importantly I will MAKE SBS GREAT AGAIN!

The school principal, Mary Flock, didn’t like that. How dare he!

A new lawsuit filed against Elon Musk by former SpaceX employees

10:12 am

Elon Musk, a target for destruction by the left
Elon Musk, a target for destruction

The lawfare won’t stop until morale improves! A new lawsuit has been filed against Elon Musk by eight former SpaceX employees, who now accuse him of sexually harassing them by his sometimes pointed tweets on X, calling those tweets “juvenile, grotesque sexual banter.”

The suit also says Musk’s tweets “had the wholly foreseeable and intentional result of encouraging other employees to engage in similar conduct.”

At SpaceX’s Hawthorne offices, the suit claims, company meetings and employees mimicked Musk’s humor. At meetings, the lawsuit alleges, senior engineers called mechanical parts “chodes” and “schlongs.” A camera that was placed on the bottom of a second-stage Falcon rocket was referred to as the “Upskirt Camera,” and a structure used by astronauts to transfer from SpaceX’s Dragon spacecraft to the International Space Station was called the “Fun Tunnel,” a euphemism for anal sex.

Read the whole article. The complaints are quite hilarious. These employees need to get a life. This is all silly stuff, hardly worth even two nanoseconds of concern.

Unfortunately, these anti-Musk employees do have a life, and it is a very sad one, consumed wholly with destroying Musk, not accomplishing anything worthwhile on their own. These eight former employees are the same ones who were fired after they published an internal letter in SpaceX calling for others in the company to denounce Musk for his tweets. Following their firing they also instigated a National Labor Relations Board (NLRB) suit against Musk, which is presently suspended because SpaceX is claiming the NLRB’s very existence is unconstitutional, and no further action on the complaint will occur until the courts decide on that claim.

This new lawsuit is simply another example of new harassment of Musk by these former employees.

FAA announces schedule for new EIS public meetings on SpaceX’s Starship/Superheavy operations at Cape Canaveral

9:48 am

FAA has now announced the schedule of public meetings in connection with the new environmental impact statement (EIS) it is doing for SpaceX’s proposed Starship/Superheavy operations at Cape Canaveral.

On June 12 and 13, the Federal Aviation Administration (FAA) will host a series of public scoping meetings to inform the public and answer questions about SpaceX’s proposal to launch Starship from Launch Complex 39A (LC-39A). There will also be a virtual meeting on June 17 for those unable to attend in person.

…Among those attending the public hearings will be representative of the Department of the Air Force, the U.S. Space Force, the U.S. Coast Guard, U.S. Fish and Wildlife Service, the Merritt Island National Wildlife Refuge, Canaveral National Seashore and SpaceX.

FAA officials claim this new EIS is required, after doing one only five years ago, because of major changes in SpaceX’s design of Superheavy. For example, it originally planned to land the rocket on a drone ship. Now it wants to catch it with the arms on the launch tower.

The FAA’s argument for this new EIS might sound plausible at first glance, but these regulations were never intended to require new environmental statements every time a project underwent changes. The goal was to make sure the environment would not be impacted by the work, and the first 2019 EIS achieved that. None of the changes SpaceX is proposing change significantly its impact on the local environment.

Moreover, the FAA has three-quarters of a century of empirical data at Cape Canaveral proving that spaceports help the local environment, not hurt it. We know without doubt that none of SpaceX’s launch plans will do harm. The FAA should get out of the way.

Instead, it is sticking its nose into everything. This new EIS is merely mission creep, government bureaucrats both covering their backsides while creating new work that increases their power and justifies bigger budgets for their existence.

Review of 4th Superheavy/Starship flight; FAA clears SpaceX for next flight

9:32 am

Link here. The article provides a detailed step-by-step review of everything that happened on the fourth Superheavy/Starship orbital test flight on June 6, 2024, as well as describing the changes being applied to Starship and Superheavy due to that flight.

However, the article also included this announcement from the FAA, stating that it will not do its own mishap investigation on that flight.

The FAA assessed the operations of the SpaceX Starship Flight 4 mission. All flight events for both Starship and Super Heavy appear to have occurred within the scope of planned and authorized activities.

While this decision means SpaceX can go ahead with the fifth test launch as soon as it is ready — no longer delayed while it waits for the FAA to retype SpaceX’s investigation and then approve it — it is unclear whether this FAA decision will allow SpaceX to attempt a tower landing of Superheavy, with the tower’s arms catching the rocket.

If the FAA has not yet approved a tower landing, I suspect SpaceX will forgo that attempt on the next launch in order to get it off the ground as soon as possible, even as it pushes the FAA for such an approval for a subsequent launch.

A new Chicken Little report: The mega satellite constellations are going to destroy the ozone layer!

1:50 pm

The American Geophysical Union, where science is no longer practiced
The American Geophysical Union, where
science is no longer practiced

We’re all gonna die! According to a new paper touted today by the PR department of the American Geophysical Union (AGU), a new study has concluded — based on computer modeling — that the many giant satellite constellations totaling tens of thousands of satellites pose a risk to the ozone layer because the aluminium used in their structures that gets vaporized upon re-entry will interact with the ozone layer and destroy it.

You can read the paper here. From the abstract:

This paper investigates the oxidation process of the satellite’s aluminum content during atmospheric reentry utilizing atomic-scale molecular dynamics simulations. We find that the population of reentering satellites in 2022 caused a 29.5% increase of aluminum in the atmosphere above the natural level, resulting in around 17 metric tons of aluminum oxides injected into the mesosphere. The byproducts generated by the reentry of satellites in a future scenario where mega-constellations come to fruition can reach over 360 metric tons per year. As aluminum oxide nanoparticles may remain in the atmosphere for decades, they can cause significant ozone depletion.

The uncertainties and biases here are hard to count. First, it is a computer model (“Garbage in, garbage out”). Second, the simulations make many assumptions, most of which cannot be confirmed, or are simply absurd. For example, the model is based on a single “typcial, small satellite” coming from a specific orbit and elevation when we know these satellites will have many variations in size, make-up, and orbits. Third, the scientists admit they use “a worst-case scenario” for determining what would happen when the satellite re-enters the atmosphere.

Finally, and most damning, the whole premise of this threat is based on a somewhat implausive chain of chemical actions.
