Florida approves expansion of spaceport territories

9:32 am

Map of potential Florida spaceports

The Florida legislature has now approved two new locations in Florida where rocket launches can take place.

Governor Ron DeSantis signed off on a bill that, as of Monday, will add South Florida’s Homestead Air Reserve Base and the panhandle’s Tyndall Air Force Base to Florida’s growing spaceport territories.

The map to the right shows the spaceport locations within Florida. While the state government might now allow launches from these locations, it is unclear if either military facility is entertaining the idea.

Regardless, the Florida government is clearly intent on encouraging and attracting this new industry to its state.

Blue Origin expands deal to fly citizens free on New Shepard

9:16 am

Blue Origin, in partnership with a non-profit, has expanded its program to fly citizens free on suborbital flights of New Shepard, adding India and what it calls “the small island developing states (SIDS)” to the recently announced deal to fly a Nigerian.

The non-profit, dubbed Space Exploration and Research Agency (SERA), has purchased one seat on each of the next half dozen flights, and will only charge passengers $2.50 for the ticket.

In an unprecedented move, SERA will allow people around the world to vote on which citizens will take the approximately 11-minute journey. Anyone living in one of the program’s partner nations can apply to secure a seat. Applicants must be proficient in English, at least 18 years of age, and meet Blue Origin’s parameters for height, weight, physical fitness, and citizenship.

Five of the seats will be allocated to specific nations, and candidates will be voted on by citizens of those nations. The sixth will be open to anyone within a SERA-partnered country and chosen through a global vote. Remaining seat assignments will be announced later this year.

Overall, this continues the PR stunt nature of Blue Origin’s suborbital New Shepard, which apparently does not have enough business to fill its passenger manifest, and thus is arranging these give-aways. While the gesture is nice, it would be far better if the company got its orbital rocket off the ground and actually began flying real cargos and passengers into space.

Is last week’s Biden-Trump debate a game-changing moment or not?

2:04 pm

Joe Biden at his February 2024 press conference
Joe Biden at his February 2024 press conference
after Justice Department special counsel Robert Hur
revealed he could not indict Biden of criminal misuse
of classified materials because Biden was “an elder
man with poor memory.”

In my life I have seen three moments in politics that appeared to change everything. In two of those cases, the appearance turned out to be true. In the third, in the end nothing changed, to the sad detriment of our country.

Last week’s debate between president Joe Biden and former president Donald Trump appears to be another such potential game-changing event. The change however will not be whether Joe Biden will be the candidate when the election finally rolls around in November, or whether even if he will win or lose the election.

The change, should it happen, will be much more funadmental. I come at this from the point of view of a historian, so bear with me as I attempt to explain.

Of the previous three game-changing moments, the first was the Watergate hearings in 1973. For months prior to those hearings, Republican politicians from all levels of government fought aggressively and with some success the accusations that president Richard Nixon had been involved in the Watergate break-in and the planning of the “dirty tricks” campaign against George McGovern leading up to the 1972 election.

The Watergate hearings however were a game-changer. It forced the entire Republican party to end its unqualified support of Nixon. The hearings, which were televised live each day and covered extensively by the press, were seen by everyone, and showed without doubt the extensive nature of Nixon’s dirty trick activity. It also illustrated bluntly the amount of duplicity and lying that Nixon and his cohorts were willing to do to defend themselves.

Unlike today, in the 1970s the American public did not tolerate lying by their politicians. Though the hearings ended in late June 1973, and Nixon held on until August 1974 before resigning, it was those hearings that ended his popularity and creditability. It was also those hearings that destroyed the creditability of the Republican Party at that time. Too many of them had backed Nixon blindly before the hearings, and were exposed themselves by those hearings as sycophants and toadies. The result: The Republican Party was wiped-out in the 1974 elections, with the Democrats gaining 53 seats in the House, 4 seats in the Senate, and 4 additional governorships.

The second game-changer occurred during the Iran-Contra affair in 1987 against Ronald Reagan. » Read more

PLD pushes for first orbital launch from French Guiana in 2025

10:40 am

The Spanish rocket startup PLD announced last week that it has invested more than $10 million in developing its own launchpad and assembly facility at France’s French Guiana spaceport, and is targeting 2025 for the first orbital launch of its Miura-5 rocket.

The launcher company PLD Space has announced today an investment of 10 million euros in MIURA 5 Launch Complex at Guiana Space Center (CSG), Europe’s spaceport in Kourou (French Guiana), owned by the French Space Agency (CNES) and the European Space Agency (ESA). With the first launch of its rocket at the end of 2025, PLD Space will become the first non-institutional launch operator that will go to orbit from this historical base.

The company is reconfiguring the launchpad used by France to launch its Diamant rocket back in the 1960s and 1970s. It will include “its own launch zone and a preparation area, comprising an integration hangar, a clean room, a control center, and both commercial and work offices.”

Right now it appears that PLD along with several other European rocket startups are going to bypass a number of American rocket startups that had had a significant headstart, but also appear to be stalled in the last year or so because of a new regulatory framework at the FAA.

New Polish suborbital rocket to be test flown from Andoya spaceport in Norway

10:26 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

A new Polish suborbital rocket, dubbed “ILR-33 Amber 2K,” and being developed by the Łukasiewicz Institute of Aviation, will do its next test flight from the Andoya spaceport in Norway.

After four consecutive test missions completed successfully in Poland, the next stage of preparations of the ILR-33 AMBER 2K to reach the edge of space will take place this year in July. Polish technology will be tested in Norway where one of the key European space centers for launching space vehicles is located.

According to this report, this rocket has a core stage with a hybrid-fueled engine plus two strap-on solid-fueled boosters, a configuration rare for suborbital rockets. After this test flight it will then begin operational suborbital flights, run by a Polish company Thorium from 2025 to 2027.

This deal is another competitive blow to the Saxaford and Sutherland spaceports in the United Kingdom. Both started commercial operations years ahead of either Andoya or Esrange, but because of red tape nothing has been yet allowed to launch from either. This Polish deal one of several for both the Andoya and Esrange spaceports that might have gone to the UK otherwise.

SpaceX studying changes to de-orbit procedures for Dragon service module

10:09 am

Because it appears the trunk section of the service module of SpaceX’s Dragon capsules actually survives re-entry, the company is now studying changes to its de-orbit procedures so that it can guarantee that trunk will not crash on land, as has happened now three times in the past two years.

The solution [a NASA official] said NASA and SpaceX are looking at involves changing deorbiting procedures. Currently, the trunk is released before the capsule performs its orbit burn. That means the trunk can remain in orbit for months before making an uncontrolled reentry.

Instead, [that NASA official] said engineers are examining doing the deorbit burn and then releasing the trunk. That would provide more control of where the trunk reenters, ensuring that any debris that survives reentry lands in unpopulated regions.

To make this new procedure work they need to recalculate the fuel requirements for doing the de-orbit burn. It also requires them to figure out when to detach the trunk after the burn. I expect SpaceX to successfully implement these changes before the next Dragon launch, whether manned or unmanned.

Ispace’s Resilience lunar lander completes thermal vacuum testing

10:01 am

The Japanese startup Ispace announced late last week that its second lunar lander, formerly names Hakuto-R2 and now dubbed Resilience, has successfully completed thermal vacuum testing and is on schedule for a launch before the end of this year.

The testing was completed at the Japan Aerospace Exploration Agency (JAXA) Tsukuba Space Center in Tsukuba, Japan, where the agency operates a large testing facility. The flight model was assembled at the facility and all payloads or testing models were integrated into the lunar lander before testing began. All test success criteria were met; ispace engineers are now reviewing the detailed data that RESILIENCE collected during the ten-day testing regime. The results will allow engineers to optimize the spacecraft thermally for spaceflight as well as improve flight operation procedures.

Thermal vacuum testing is conducted in a large chamber that allows the lunar lander to experience conditions similar to what it will face during its journey through outer space including extreme temperatures in a vacuum environment. Initial test results indicated successful operation of power systems, guidance, navigation and control (GNC) equipment, radio communications, and thermal control of the lander while simulating an actual spaceflight. During testing in the chamber, ispace operators utillized the lander’s onboard radio to assess connections, send commands to, and receive telemetry from the lander, further simulating actual flight operations.

This lander will also carry a mini-rover, and will be launched by a Falcon 9 rocket. The company’s press materials don’t name a location for the lunar landing spot, though one must have been chosen. I suspect, as this mission is a precursor to Ispace’s first NASA lunar landing mission set for 2026, it will be sent to the same location as Ispace’s first Hakuto-R1 test mission, which got to within three miles but then crashed because sensors thought it was just above the surface and shut off the engines prematurely.

Japan’s H3 rocket launches successfully for the second time

9:24 pm

Japan’s space agency JAXA today successfully completed the second successive launch of its new H3 rocket, placing an Earth observation satellite into orbit.

This was the third launch of the H3, with the first in May 2023 a failure, and the second a success in February 2024.

I have embedded the video of the launch below, cued to T-15 seconds. This was Japan’s third launch in 2024, exceeding last year’s total of two and matching its total from 2024.

The leader board for the 2024 launch race remains unchanged:

69 SpaceX
29 China
8 Russia
8 Rocket Lab

American private enterprise still leads the world combined in successful launches, 80 to 44, while SpaceX by itself still leads the entire world, including other American companies, 69 to 55.

Chinese first stage breaks free during static fire test; launches, crashes

10:08 am

The first stage of Chinese pseudo-company Space Pioneer’s new Tianlong-3 rocket, intended for its first launch this summer, crashed and burned today during a static fire test when the equipment holding it down failed.

Video of this spectacular failure is embedded below. The rocket is essentially a copy of SpaceX’s Falcon 9, with that first stage designed to eventually become reusuable in the same way.

This pseudo-company recently announced it had raised $207 million in private investment capital, bringing the total it has raised to $552 million. It was also the first Chinese pseudo-company to launch an orbital rocket using liquid fuels, successfully doing so with its Tianlong-1 rocket in April 2023.

Though static fire engine tests have failed before, this appears to be the very first ever to actually break free and launch itself. Fortunately, according to both government and Space Pioneer officials, no one was hurt.

What impact this will have on China’s pseudo-private rocket industry is unknown. This incident isn’t the first, with a tank test by pseudo-company Landspace in January 2024 injuring three.

Moreover, there are hints that the Chinese government might be repossessing control from these companies (as I have expected from the start). Landspace, as well as two other pseudo-companies, Expace and Ispace, have been testing methane-fueled rockets, with Landspace having completed one orbital launch in December 2023 and all three successfully completing hop tests of their first stages.

Last week however a Chinese government agency successfully completed a 10-kilometer hop test of its own methane-fueled first stage. I wonder how much of its design was developed independently, or taken from these three pseudo-companies by the government. I suspect the latter, since none of these companies are really privately owned. They might seem so, but the communists can confiscate everything they have at any moment, and clearly supervises and dictates what they do, step-by-step.

France awards contract to French startup to launch two robotic satellite servicing missions

10:03 am

Capitalism in space: France has awarded the French startup Infinite Orbits a contract to launch two robotic satellite servicing missions, one to attach itself to a still-unnamed satellite to extend its life, and a second to test rendezvous and proximity maneuvers near a defunct and thought-to-be tumbling weather satellite.

The key tidbit however is that the contract award is part of a French government program to encourage commercial space:

The France 2030 initiative is a €54 billion investment programme that aims to transform sectors of the French economy with technological innovation.

I was unaware of this French government program. It appears it signals a shift in financial support from the European Space Agency’s commercial entity Arianespace to new competitive French companies. If so, this is a very good sign for its aerospace industry.

SpaceX and China complete launches

9:44 am

Both SpaceX and China completed launches in the past 12 hours. First, SpaceX last night launched a package of National Reconnaissance Office reconnaissance satellites, its Falcon 9 rocket lifting off from Vandenberg in California. The first stage completed its eighth flight, landing on a drone ship in the Pacific. The two fairings completed their seventh and thirteenth flights respectively.

Then, early today China launched a new communications satellite, its new Long March 7A rocket lifting off from its coastal Wenchang spaceport. Video of the liftoff can be seen here.

The leaders in the 2024 launch race:

69 SpaceX
29 China
8 Russia
8 Rocket Lab

American private enterprise still leads the world combined in successful launches, 80 to 43, while SpaceX by itself still leads the entire world, including other American companies, 69 to 54.

Clap Yo’ Hands – Fred Astaire & Kay Thompson

6:01 pm

An evening pause: From the 1957 musical Funny Face. I only saw this film for the first time last week, and as I watched this scene I was most amused by Astaire’s dance moves in the second half of this number. “Why, Astaire is doing Gene Kelly!” I exclaimed to Diane.

Both men had their own styles. Kelly was into grand film presentations, acrobatics, and the soft shoe. Fred Astaire was into dance, in all its forms. If you are familiar with Kelly’s dance style you will see immediately how Astaire is parodying it, but with great respect.

Astaire’s partner in this number is Kay Thompson, in her only starring movie role. Thompson had an amazing artistic career, from writer (the Eloise children’s books) to vocal coach for Judy Garland and Gene Kelly to recording artist to night club performer. It is a shame we don’t have more films of her singing and dancing.

Sixteen Nobel economists once again prove that our “expert” class is expert at nothing

1:57 pm

Our modern intellectual class
Our modern intellectual class

Earlier this week a group of sixteen Nobel laureate economists issued a public letter endorsing Joe Biden’s economic agenda and claiming that a return of Donald Trump to the White House would lead to economic ruin.

“We believe that a second Trump term would have a negative impact on the U.S.’s economic standing in the world, and a destabilizing effect on the U.S.’s domestic economy,” the economists write in the letter. “Many Americans are concerned about inflation, which has come down remarkably fast. There is rightly a worry that Donald Trump will reignite this inflation, with his fiscally irresponsible budgets.”

You can read their letter here. It was signed by the following (the date of their Nobel award in parenthesis):

George A. Akerlof (2001), Sir Angus Deaton (2015), Claudia Goldin (2023), Sir Oliver Hart (2016), Eric S. Maskin (2007), Daniel L. McFadden (2000), Paul R. Milgrom (2020), Roger B. Myerson (2007), Edmund S. Phelps (2006), Paul M. Romer (2018), Alvin E. Roth (2012), William F. Sharpe (1990), Robert J. Shiller (2013), Christopher A. Sims (2011), Joseph Stiglitz (2001), and Robert B. Wilson (2020).

What is hilarious about their letter is how it exposes these so-called economic giants as partisan hacks. A dive into their campaign contributions finds that eleven are donors to Joe Biden or the Democrats, while the remaining five have all previously endorsed Biden publicly. Before the 2020 election two of these sixteen economists signed a similar letter, calling for Joe Biden’s election, claiming he would “…build an economy that works for all Americans.” In 2021 thirteen of these same economists then followed up with another letter, endorsing all of Biden’s spending proposals then before Congress (costing an expected $1.9 trillion).

A comparison between the claims in all three letters and what actually happened also reveals how little these economists know about economics. As noted at this City Journal article by James Piereson:

New update on SpaceX’s preparations for future Starship/Superheavy test launches

10:06 am

Link here. Lots of progress described, all suggesting SpaceX continues to target late July for the next test orbital flight. Very much worth reading.

The article repeatedly suggests the work to prepare the launch tower at Boca Chica to catch a returning Superheavy means the next launch will attempt such a catch, but in truth there is no evidence such a thing is planned, other than a single tweet by Elon Musk. As the article finally admits in its next-to-last paragraph,

Starship can now fly missions that have very similar profiles to Flight 4 with the existing FAA license, but a license modification is needed for any catch attempt. If Flight 5 does indeed proceed with a catch attempt at the tower for Booster 12, additional paperwork will need to be filed for this license modification.

I continue to expect SpaceX to propose such a catch on a later flight. The tower work at Boca Chica could be the company doing the necessary work to prove to the FAA that a amended launch license process should be issued, but not for the next flight.

Indonesia government offering proposed launch site to SpaceX and others

9:57 am

Indonesia proposed spaceport on Baik

As part of its effort to promote a long term space industry development plan, Indonesian officials have repeatedly been offering a proposed launch site to SpaceX and others on government land on the island of Biak off the coast of New Guinea.

The map to the right shows the location. First SpaceX and China were offered use of Baik. Neither has accepted. Then,

As recently as 2023, BRIN officials promoted their spaceport plans at the G20 Space Economy Leaders’ Meeting and Asia-Pacific Regional Space Agency Forum. China, Russia, Japan, South Korea and India were invited as potential partners, but none signed on.

Meanwhile, the article says Indonesia hopes to launch 19 satellites in 2025, using a variety of commercial launchers.

European weather satellite company cancels launch contract with Ariane-6, switches to SpaceX

9:37 am

We now know the reason why an Arianespace official on June 26th demanded new legislation requiring all European payloads to launch on European rockets. Today it was revealed that the European weather satellite company Eumetsat has canceled a launch contract on an Ariane-6 rocket and instead switched to SpaceX’s Falcon 9.

Late yesterday, French news outlet Le Monde reported that the executive committee of Eumetsat, the European meteorological satellite agency, had asked the agency’s board of directors to cancel a contract it signed with Arianespace four years ago to launch its Meteosat MTG-S1 satellite. The mission would have been flown aboard the third Ariane 6 flight, which is expected to be launched in early 2025. The satellite will now be launched aboard a SpaceX Falcon 9 rocket.

Not surprisingly, another French official today — Philippe Baptiste, the head of France’s CNES space agency — once again demanded action to require European companies to use European rockets. In his whining however he revealed an amazing inability to understand why this decision was made.

“How far will we, Europeans, go in our naivety. … I am impatiently waiting to understand what reasons could have led Eumetsat to such a decision at a time [when] all major European space countries as well as the European Commission are calling for launching European satellites on European launchers.”

The reasons why are quite obvious, and if this guy can’t recognize them then there is little hope the European Ciommision will ever figure out how to compete. Not only is the cost for a Falcon 9 launch likely one third that of an Ariane-6, it is a proven launcher. Ariane-6, four years behind schedule, won’t make its first launch until July 9, 2024, assuming all goes as planned. Eumetsat officials probably decided they couldn’t afford the extra cost and risk.

Russian inspector satellite now approaching its eleventh communications satellite

9:22 am

A Russian inspector satellite dubbed Luch-2 and launched in March 2023 is now maneuvering to make a close approach and surveillance of an eleventh commercial communications satellite in geosynchronous orbit.

The company is forecasting that Luch 2’s next object of interest is the Intelsat 1002 communications satellite. “Luch 2 is expected to perform an additional maneuver to stop its drift near Intelsat 1002 on June 28 if it continues its past pattern of behavior,” Slingshot said. This behavior mirrors that of its predecessor, Luch Olymp-K-1, which has been known for similar intelligence-gathering activities.

The close approaches have ranged from 12 miles to 142 miles, with most getting inside 100 miles distance.

It is unlikely Russia is testing robotic maneuvering technology, as it has had this capability since the 1970s. More likely it is testing the ability to intercept communications from such satellites, though it is unknown whether Luch-2 has done so. Visiting multiple satellites would also permit it to test against a wide variety of technology.

China: Chang’e-6 collected more than four pounds of material from Moon

9:11 am

According to China’s state-run press today, its Chang’e-6 sample return mission collected 1,953.2 grams, more than four pounds, from the Aitkin Basin on the far side of the Moon.

Based on preliminary measurement, the Chang’e-6 mission collected 1,935.3 grams of lunar samples, according to the CNSA. “We have found that the samples brought back by Chang’e-6 were more viscous compared to previous samples, with the presence of clumps. These are observable characteristics,” Ge Ping, deputy director of the CNSA’s Lunar Exploration and Space Engineering Center, who is also the spokesperson for the Chang’e-6 mission, told the press at the ceremony.

Researchers will then carry out the storage and processing of the lunar samples as planned and initiate scientific research work.

If all goes as plans, they will be ready to begin distributing samples for study to Chinese researchers in about six months.

Amazon delays offering Kuiper broadband service to ’25

9:06 am

Though Amazon still has plans to begin launching satellites of its internet Kuiper constellation late this year, it revealed yesterday that it will now delay operational availability of the service to the public until 2025.

Amazon had earlier aimed to start deploying more than 3,200 satellites in the first half of 2024 to begin beta trials with potential customers, including Verizon in the United States. However, the company now expects to ship the first production satellites this summer to Florida for the launch with United Launch Alliance from its recently opened factory in Kirkland, Washington.

In order to offer the product to the public Amazon needs to have a certain number of satellites in orbit. Moreover, the company’s FCC license required it to launch half of this constellation by 2026, so meeting that deadline is getting increasingly difficult. Amazon has contracts to launch satellites 46 times on ULA rockets (8 on Atlas-5 and 36 on Vulcan), 27 times on Blue Origin’s New Glenn, 18 times on ArianeGroup’s Ariane-6, and 3 times on SpaceX’s Falcon-9.

By the time Amazon begins selling Kuiper, Starlink will have been available for about four years. For Amazon to grab market share will be thus difficult, unless it offers its product for significantly less.

Susan Boyle – I Dreamed a Dream

An evening pause: This was her first appearance as a singer, on the television show Britain’s Got Talent, airing on April 11, 2009. It is a glorious TV moment. Much of it I think was planned, at least by the producers, though the judges and audience almost certainly had no idea what they were about to hear. Enjoy. Fun to watch over and over.

Supreme Court to SEC: Use of in-house administrative law judges unconstitutional

1:43 pm

SEC: no longer above the law
SEC: no longer above the law

The Supreme Court today ruled 6-3 that the SEC has violated the Constitution with its use of in-house administrative law judges to rule on its various securities fraud cases.

The agency, like other regulators, brings some enforcement actions in internal tribunals rather than in federal courts. The S.E.C.’s practice, Chief Justice John G. Roberts Jr. wrote for a six-justice majority in a decision divided along ideological lines, violated the right to a jury trial. “A defendant facing a fraud suit has the right to be tried by a jury of his peers before a neutral adjudicator,” the chief justice wrote.

This ruling against the use of administrative law judges has a direct bearing on SpaceX’s own lawsuit [pdf] against the National Labor Relations Board (NLRB). In January the NLRB filed a complaint against SpaceX, accusing it of firing eight employees illegally for writing a public letter criticizing the company in 2022. Rather than fight that complaint directly, SpaceX’s response was to file a lawsuit challenging the very legal structure of the NLRB itself, including its use of administrative law judges.

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.

Juno infrared data confirms existence of at least eleven lava lakes on Io

11:53 am

Cartoon describing Io's lava lakes
Click for original image.

Using infrared data from the Jupiter orbiter Juno, obtained during a close fly-by in May 2023 of the moon Io, scientists have identified what appear to be at least eleven active lava lakes, all filled with liquid magma under a surface crust and having a stable perimeter that apparently does not overflow the rim.

You can read the research paper here. The graphic to the right is figure 6 from the paper, describing two models for explaining why the lava in these lakes never rises high enough to pour out.

Unlike the April fly-by, which got as close as 10,777 miles and produced some amazing imagery, the May fly-by only got within 22,000 miles, but its course allowed Juno’s infrared instruments to collect good global data for six hours.

The JIRAM data reveal a common set of thermal characteristics for at least ten patera, with bright “thermal rings” around the perimeter of their floors. Loki, Surt, Fuchi, Amaterasu, Mulungu, Chors, and Dazhbog paterae, two unnamed paterae (here referred to as UP1 and UP2), and two other potential additional paterae (not discussed further because the spatial resolution is poor), all show the same pattern of surface temperatures.

That data suggested that each patera was a hot lava lake, with a stable rim in which little magma ever overflowed. As the scientists conclude in their paper, “Present findings highlight Io’s abundant lava reserves, resembling lava lakes on Earth in some ways, yet distinctly different from any other phenomena observed in the Solar System.” The scientists also note that no missions are being planned right now to get a better look at Io.

SpaceX now valued at $210 billion

10:46 am

As part of another sale of insider shares to raise more private investment capital, SpaceX has now been valued at $210 billion.

SpaceX will sell shares at $112 each in the tender offer, the Bloomberg report said, with the newer sales valuing the company much higher than a $180 billion valuation seen during a tender offer in December.

The report does not say how many shares SpaceX hopes to sell, or how much total new capital it hopes to obtain. Previous such sales have raised a total of $12 billion, money the company is using to develop both its Starlink constellation and its Starship/Superheavy rocket.

Engineers revive instrument on Perseverance

10:41 am

Engineers in the Perseverance science team have successfully gotten a stuck cover moved so that it no longer blocked a camera and spectroscopic instrument mounted on the rover’s robot arm from gathering data.

The cover had gotten stuck partially closed in January 2024.

Analysis by the SHERLOC team pointed to the malfunction of a small motor responsible for moving the protective lens cover as well as adjusting focus for the spectrometer and the Autofocus and Context Imager (ACI) camera. By testing potential solutions on a duplicate SHERLOC instrument at JPL, the team began a long, meticulous evaluation process to see if, and how, the lens cover could be moved into the open position.

Among many other steps taken, the team tried heating the lens cover’s small motor, commanding the rover’s robotic arm to rotate the SHERLOC instrument under different orientations with supporting Mastcam-Z imagery, rocking the mechanism back and forth to loosen any debris potentially jamming the lens cover, and even engaging the rover’s percussive drill to try jostling it loose. On March 3, imagery returned from Perseverance showed that the ACI cover had opened more than 180 degrees, clearing the imager’s field of view and enabling the ACI to be placed near its target.

Because the cover could no longer be moved, focusing was no longer possible. They then had to use the robot arm to do a long sequence of careful focus tests to determine the best distance for sharp imagery, which was found to be about 1.58 inches.

As is usual for all Perseverance press releases from NASA, this one starts out with the lie that the purpose of this instrument is to “look for potential signs of ancient microbial life.” That is false. While finding such things would be possible with SHERLOC, its real purpose is to study close-up the geology of Mars. To claim its purpose is to look for microbial life is sheer blarney.

Chang’e-6 sample return capsule opened in China

According to China’s state-run press, the return capsule carrying samples from the far side of the Moon was opened yesterday “during a ceremony at the China Academy of Space Technology under the China Aerospace Science and Technology Corporation in Beijing.”

No other details were released. The pictures at the link appear to show engineers removing an internal capsule from inside the return capsule, which makes sense. For many scientific reasons the actual samples must be kept sealed from the Earth’s atmosphere in order to make sure they are not contaminated. The actual lunar material will not be exposed and touched until it is placed inside a very controlled environment.
