Starliner decision expected tomorrow, August 24

9:04 am

According to a NASA update today, the agency will hold “an internal Agency Test Flight Readiness Review” to discuss whether to return Starliner manned or unmanned on Saturday morning, August 24, 2024 and then hold a press conference immediately afterward to discuss the results of that review.

What makes this review and press conference different from all previous Starliner reviews and conferences is that NASA administrator Bill Nelson will attend.

NASA Administrator Bill Nelson and leadership will hold an internal Agency Test Flight Readiness Review on Saturday, Aug. 24, for NASA’s Boeing Crew Flight Test. About an hour later, NASA will host a live news conference at 1 p.m. EDT from the agency’s Johnson Space Center in Houston.

The only reason a politico like Nelson would participate in such proceedings is because he has taken control of the decision-making process, and will make the decision himself. The review is likely to educate him as best as can be done in this short time, and he will then decide whether the two astronauts who launched on Starliner, Butch Wilmore and Suni Williams, will return on it in the next week or so, or will stay on board ISS until February 2025 and return on the next Dragon crew capsule scheduled to launch to ISS in late September.

Nelson might have decided to get involved on his own, but I am certain that if so it was strongly “encouraged” by officials above him in the White House. There is an election coming up, and the risks involved in using Starliner to return the astronauts must be weighed in connection not just with its engineering concerns but with its political ramifications also.

Nelson’s decision will also provide us a strong indication of a future Harris administration’s attitude toward space.

Chinese scientists find method to extract water from Chang’e-5 lunar samples

12:04 pm

Proposed concept for extracting water from lunar regoilth
Proposed concept for extracting water from
lunar regoilth

Chinese scientists have found that by heating Chang’e-5 lunar samples to 1,700 degrees Fahrenheit it is possible to extract a significant amount of water. From the paper’s abstract:

FeO and Fe2O3 are lunar minerals containing Fe oxides. Hydrogen (H) retained in lunar minerals from the solar wind can be used to produce water. The results of this study reveal that 51–76 mg of H2O can be generated from 1 g of LR [lunar regolith] after melting at temperatures above 1200 K. This amount is ∼10,000 times the naturally occurring hydroxyl (OH) and H2O on the Moon. … Our findings suggest that the hydrogen retained in LR is a significant resource for obtaining H2O on the Moon, which are helpful for establishing scientific research station on the Moon.

A video in Chinese (hat tip BtB’s stringer Jay) that describes this research can be found here. (If any of my readers understands Chinese and can provide a translation of this video’s narration, I would be very grateful.) It includes an artist’s rendering (screen capture to the right) showing how such a system on the Moon could work to extract water from the soil. Sunlight would be focused by a lensed mirror into a glass-domed container, heating the ground. The water would evaporate, condense on the glass and be sucked into a tube that would transfer it to a water tank.

This design is of course very simple and preliminary. According to Jay, “They need to heat the soil to 1000℃ (1832°F) to get the iron oxide in the lunar soil to split, the oxygen combines with hydrogen to make water and iron (melting point of iron is about 1500℃). You will need a nuclear reactor to produce that much power for an inductive furnace to get that hot. Doing the calculation, it would take about 245kw to heat up a metric ton of dirt in one hour to a 1000℃ degrees. It could be done slower over 24 hours at 10kw.”

Despite the technical difficulties getting such equipment operational on the Moon, that this research suggests water can be produced practically anywhere on the lunar surface is signficant. It suggests that even if no easily accessible water ice is found in the permanently shadowed craters at the poles, lunar bases still have viable options for obtaining water, and they don’t have even be at the poles.

New port for big cruise ships dropped in Florida because it threatens space operations

10:02 am

A plan to build a new terminal in Port Canaveral for the large cruise lines has now been dropped because the constant arrival and departure of those ships would hinder launches from both Cape Canaveral as well as the Kennedy spacport.

On Aug. 2, Florida Department of Commerce Secretary J. Alex Kelly and Florida Department of Transportation Secretary Jared Perdue expressed dismay about cruise-terminal plan changes that could affect the space industry. Kelly and Perdue, in a letter, said that unless the port returns to earlier plans for the berth, the Department of Transportation will shift investments to other seaports and spaceports, and the Department of Commerce will halt funding for Port Canaveral projects.

These threats were enough to cause the port to drop its plans.

This story strongly suggests that the Florida state government views the future income from spaceport operations to far exceed that of the tourist cruise business, and does not wish the latter to interfere with the former’s growth in any way.

Proposed commercial spaceport in Nova Scotia teams up with Voyager Space

9:54 am

The proposed commercial spaceport in Nova Scotia that was first proposed by the company Maritime Launch Services in 2017 has now signed a partnership deal with the space station company Voyager Space.

Voyager, through its Exploration Segment, will provide comprehensive engineering, design and fabrication support to Maritime Launch, leveraging more than six decades of combined aerospace and defense technology experience. Voyager will bring its decades of commercial spaceflight engineering, manufacturing, and operations capabilities to provide engineering design and development and buildup of select portions of the launch site on behalf of Maritime Launch. Voyager will work alongside Maritime Launch to analyze launch client requirements and integrate them into the current site layout.

Maritime’s original plan had been to provide a launch location and rocket (produced by a Ukrainian company). Satellite companies would sign with both for launch services. The invasion of the Ukraine by Russia in 2022 killed that arrangement. So did red tape, as the Canadian government only passed a law allowing spaceports to make deals with international partners at the start of August.

It appears Maritime has realized that without that rocket partner, it needs another experienced partner to help build the spaceport itself and make sure launches by many different rocket companies are done safely. It has now hired Voyager to do this, since that company is leading the Starlab space station consortium that includes many very experienced companies, including Lockheed Martin, Northrop Grumman, Airbus, Mitsubishi, and the European Space Agency.

First SLS/Orion manned mission faces new delays because of Orion heat shield issues

9:39 am

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”

Because the damage to the heat shield on the Orion capsule that flew around the Moon in late 2022 remains somewhat unexplained, NASA is considering delaying the next SLS/Orion mission, presently planned for September 2025 and intended to be the first Artemis flight to carry humans and take them around the Moon.

The heat shield, already installed at the base of the Orion spacecraft, will take the brunt of the heating when the capsule blazes through Earth’s atmosphere at the end of the 10-day mission. On the Artemis I test flight in late 2022, NASA sent an Orion spacecraft to the Moon and back without a crew aboard. The only significant blemish on the test flight was a finding that charred chunks of the heat shield unexpectedly stripped away from the capsule during reentry as temperatures increased to nearly 5,000° Fahrenheit (2,760° Celsius).

The spacecraft safely splashed down, and if any astronauts had been aboard, they would have been fine. However, the inspections of the recovered spacecraft showed divots of heat shield material were missing.

Two years later, despite extensive investigation and analysis, it appears NASA has not yet identified the root cause of the damage. The ablative material used on Orion was similar (though not identical) to the material used successfully on numerous other heat shields since the 1960s, yet it did not perform as expected.

NASA is presently facing three options. Do nothing and fly the next mission as planned, with four astronauts. It could rethink the trajectory used during re-entry, though this would likely not change things significantly unless the astronauts don’t go around the Moon as planned. Or it could change the heat shield itself.

The first two options are very risky, considering the unknowns. The latter involves a major delay of at least two years.

A decision must be made soon however. To meet the agency’s schedule it must begin stacking SLS’s two solid-fueled strap-on boosters next month. Those boosters have a limited life expectancy originally estimated to be one year. In the first unmanned Artemis test flight in 2022, NASA because of other delays stretched that life span to two years, and had no problems with the launch. If it stacks the boosters now and then has to delay for two more years to redesign Orion’s heat shield, those boosters will have been stacked for three years when launched.

Considering how seriously NASA is taking the issues with Starliner, which are likely not as serious as a heat shield that doesn’t work reliably, it would seem insane for NASA to launch Orion manned without fixing its own problem. And yet, for more than two decades NASA has consistently not demanded the same safety standards for SLS that it has demanded for the private commercial rocket startups. We shall see if this pattern now persists.

I continue to believe that the first Artemis lunar landing will not take place before 2030 (at least six years behind schedule). This heat shield dilemma only strengthens that prediction.

Pushback: Parent sues Denver school board and four of its board members for slander

2:10 pm

The slanderers on the Denver Board of Education
The accused slanderers still serving on Denver’s Board of Education.
Click for details about each.

Fight! Fight! Fight! Kristen Fry, a parent in Denver, has now sued the four members of the Denver school board who teamed up with a political consultant they worked with to falsely accuse her of assaulting that political consultant at a public board meeting while also using a vicious racial slur against him.

Fry had been part of a group of parents and teachers that were desperately trying to get this board to change its policies in the schools that had were allowing violence to run rampant From Fry’s lawsuit [pdf]

In the period leading up to 2022-23 school year, the BOE [Board of Education] defendants pursued a number of significant changes to DPS [Denver Public Schools] policy that had severe consequences for the educational and safety environment in DPS schools.

Among other things, in an initiative spearheaded by Mr. Anderson, and supported by the other defendants, DPS removed public safety officers from district schools because of purported racial inequities in disciplinary enforcement. DPS further replaced clear behavioral and accountability rules with what are sometimes termed “restorative justice” principles that often have the effect of leaving students (especially low-income students) vulnerable to disruptive and even criminal behavior by their classmates. For example, under the new rules, schools were required to allow potentially violent students, including students facing criminal charges such as robbery and attempted murder, to attend in person, even where against the advice of law enforcement authorities.

These policies were doing nothing but bring chaos and violence to the schools, while seriously degrading the learning environment. The parents, teachers, and even students repeatedly attempted in private and in public to convince the board its policies were not working.

In every case, this effort was met with anger, disrespect, and retailation by the board. In one case the board immediately terminated a principal for expressing dissent about their policies to a television news reporter. In the case of Fry, these thugs not only repeated these false claims against her in many public forums, they teamed up to file criminal charges against her.

The massive scale of Mars’ biggest canyon

12:24 pm

Overview map

The south rim of Valles Marineris
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on May 24, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled merely a “terrain sample” by the camera team, it was likely taken not as part of any particular research project, but to fill a gap in the picture-taking schedule in order to maintain the camera’s proper temperature.

When the camera team needs to do this, they try to pick interesting targets within the required timeframe. Sometimes they succeed, sometimes not. In today’s example, they succeeded quite well. As shown by the overview map above, this picture captures (as indicated by the rectangle) the top of the southern rim of Valles Marineris, the biggest canyon on Mars and quite possibly the biggest in the entire solar system.

For scale, the drop from the rim to the low point in this picture is about 9,000 feet. That’s a 1,000 feet more than the drop from the north rim of the Grand Canyon to the canyon bottom at the Colorado River. In Valles Marineris however our descent has barely begun. To get to the bottom of the southern canyon here you still need to drop 15,000 more feet, for a total descent of 24,000 feet, an elevation change similar to most of the mountains in the Himalayas.

Nor are you yet at the bottom. If you climb over the ridge of 18,000-foot-high mountains that bisect Valles Marineris at this point, you can drop down even further, to a depth 31,000 feet below the southern rim.

Mount Everest is just over 29,000 feet high, which means if placed inside Valles Marineris is peak would still sit 2,000 feet below the rim.

The photo itself highlights part of the erosion process that formed Valles Marineris. This is the dry tropics, so no water was involved in shaping this terrain for many eons. Instead, what appear to be flows within the hollows is alluvial fill, material that over time breaks off and rolls downhill, filling the slopes below. Erosion will grind this material into smaller particles, so given enough time it flows almost like sand.

Pragyan data confirms theory that the Moon’s surface was once largely covered with molten lava oceans

Data from India’s Pragyan lunar rover that landed in the high southern latitudes of the Moon in August 2023 has now confirmed the theory that the Moon’s surface was once largely covered with molten lava oceans.

Santosh Vadawale, an X-ray astronomer at the Physical Research Laboratory in Ahmedabad, India, and his colleagues analysed radiation data collected by the APXS [one of Pragyan’s instruments], and used this information to identify the elements in the regolith and their relative abundances, which, in turn, revealed the soil’s mineral composition. The team found that all 23 samples comprised mainly ferroan anorthosite, a mineral that is common on the Moon. The results were reported in Nature today.

“It’s sort of what we expected to be there based on orbital data, but the ground truth is always really good to get,” says Lindy Elkins-Tanton, a planetary scientist at Arizona State University in Tempe.

Previous landers obtained similar results. However, the Chandrayaan-3 samples are the first from the subpolar region: previous landers visited equatorial and mid-latitude zones. Together, this suggests that the composition of the regolith is uniform across the Moon’s surface.

These results are no surprise, but they confirm the global nature of the Moon’s early molten history. More important, they demonstrate that India now has the capability to send landers and rovers to other planets that are also capable of doing real research.

Astroscale signs deal with JAXA to de-orbit old rocket upper stage

9:52 am

abandoned upper stage, taken by ADRAS-J
Click for original image.

The Japanese orbital tug startup Astroscale has now signed the final deal with Japan’s space agency JAXA to de-orbit the old H2A rocket upper stage that the company is presently flying a demonstration rendezvous and proximity mission dubbed ADRAS-J.

The photo to the right was taken by ADRAS-J in the spring, shortly after it rendezvoused with the stage. The data from this demo mission has not only shown Astroscale’s spacecraft can autonomously rendezvous and fly in close formation to the stage, the stage itself is in excellent condition after fifteen years in space.

The ADRAS-J follow-on active debris removal spacecraft, ADRAS-J2, will similarly attempt to safely approach the same rocket body through [rendezvous and proximity operations], obtain further images, then remove and deorbit the rocket body using in-house robotic arm technologies.

If successful, Astroscale will have the capability to offer this surface to others, both governments and private concerns, thus making the removal of space junk a viable business. Until the past decade, most upper stages ended up in orbit where they remain for long periods. There are a lot of such older stages. Some end up burning up in the atmosphere harmlessly, while others break up in orbit and produce a lot of debris that is a threat to other spacecraft. Astroscale’s mission here will demonstrate the ability to remove such stages.

The North Star has spots!

9:38 am

The spoted surface of Polaris
Click for original image.

Astronomers using an array of six ground-based telescopes have obtained best new data of Polaris, the North Star, including the first rough image of its surface, and discovered sunspots on its surface.

You can read the paper here [pdf]. The image to the right, taken from figure 4 of the paper, shows the surface as seen by the telescopes over two nights in April 2021. Polaris is what astronomers call a Cepheid variable star, which changes brightness on a very precise schedule as its diameter grows and shrinks. In the case of Polaris, that variation is four days long. The star’s brightness itself varies only slightly, and over the decades has even at times appeared to cease its variations.

As the true brightness of Cepheids is very predictable based on their pulse rate, these stars are one of the main tools astronomers use to determine distances to other galaxies. Knowing more about them thus has great importance to cosmological research.

The orbital motion showed that Polaris has a mass five times larger than that of the Sun. The images of Polaris showed that it has a diameter 46 times the size of the Sun.

The biggest surprise was the appearance of Polaris in close-up images. The CHARA observations provided the first glimpse of what the surface of a Cepheid variable looks like. “The CHARA images revealed large bright and dark spots on the surface of Polaris that changed over time,” said Gail Schaefer, director of the CHARA Array. The presence of spots and the rotation of the star might be linked to a 120-day variation in measured velocity.

The researchers plan to take regular images again of Polaris to better track the changes to its surface.

NASA delays Starliner return decision to end of month

9:17 am

In a short FAQ posted by NASA today, the agency quietly revealed that the decision on whether to bring Starliner back with its astronauts on board has been delayed till the end of August.

NASA now plans to conduct two reviews – a Program Control Board and an Agency Flight Readiness Review – before deciding how it will safely return Wilmore and Williams from the station. NASA expects to decide on the path forward by the end of August.

It appears the agency has decided to bring more people into the decision-making process. In the briefing last week, it was then planning only one review, expected to be completed before the end of this week. It now sounds like a second review will occur after the first, pushing the decision back one more week.

All of NASA’s actions in the past three weeks have suggested an increasing involvement by upper management, possibly including White House officials. With an election coming up, the politicans who are supposed to be in charge have apparently inserted themselves into this process and are demanding greater review. I expect in the end the decision will fall to them, and might even be announced by NASA administrator Bill Nelson himself.

These actions have also suggested that upper management does not like the risks involved in returning the crew on Starliner. Politicians do not like to have bad things happen on their watch. We should therefore not be surprised if the decision is made to send Starliner home unmanned.

Juice completes Earth fly-by, heads for Venus fly-by

9:07 am

Click for original image.

The European probe Juice yesterday successfully completed a close fly-by of the Earth and was thus successfully slingshoted on its way to its next fly-by, of Venus, on its way to Jupiter.

This fly-by was actually a double event. First Juice zipped past the Moon the day before, coming within 435 miles. Then, only one day later it passed the Earth at a distance of 4,230 miles, thus completing the first dual fly-by of the both the Earth and the Moon.

The flyby of the Moon increased Juice’s speed by 0.9 km/s relative to the Sun, guiding Juice towards Earth. The flyby of Earth reduced Juice’s speed by 4.8 km/s relative to the Sun, guiding Juice onto a new trajectory towards Venus. Overall, the lunar-Earth flyby deflected Juice by an angle of 100° compared to its pre-flyby path.

The inherently risky flyby required ultra-precise, real-time navigation, but is saving the mission around 100–150 kg of fuel. In the month before the flyby, spacecraft operators gave Juice slight nudges to put it on exactly the right approach trajectory. Then they tracked Juice 24/7 between 17–22 August.

The Venus fly-by will occur in August 2025, followed by additional Earth flys in September 2026 and January 2029. The spacecraft will finally arrive in Jupiter orbit in July 2031, where it is designed to study the large icy moons (Europa, Gandymede, and Calisto) of that gas giant.

What the heck caused these cones to align on Mars?

Click for original image.

Time for another “What the heck?” cool image! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 23, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team labels as “longitudinally aligned cones”.

To my eye the cones visibile in this picture seem more aligned latitudinally, to the east-west, instead of longitudinally, north-south, but the larger view in the inset on the overview map below shows that on a larger scale, the cones do appear aligned in a north-south direction.

Either way, this is one of those photos from Mars orbit that leaves me entirely baffled. The cones and the flow feature that cuts across the middle of the image might be either volcanic or glacial, but it is beyond my pay grade to explain what caused this patch of aligned cones.

Court: Cop who arrested an innocent citizen illegally has no immunity

2:06 pm

Still in effect
Still in effect

A federal three-judge panel has now ruled that a policeman who illegally arrested an innocent citizen simply because that person had a concealed carry permit cannot claim qualified immunity from suit or prosecution.

The actions of the policemen, Nicholas Andrzejewski, were incredibly inappropriate and abusive.

On November 12, 2018, Basel Soukaneh’s life was significantly disrupted. Soukaneh was looking for a house he was considering purchasing, but the GPS on his phone, held in a holder on the dash of his car, had frozen. He was unfamiliar with the area. Soukaneh pulled over to correct the problem, left the engine running, and had the interior lights on. A Waterbury police officer quickly knocked on his window and demanded to see his driver’s license. Soukaneh handed him the license and his legal concealed carry permit, then told the officer where his firearm was located in the vehicle.

The officer, Nicholas Andrzejewski, grabbed Soukaneh, dragged him from the car, and violently handcuffed him, causing significant pain. Andrzejewski then stuffed Soukaneh in the back of his police car and searched Soukaneh’s car, including the trunk. Several other officers came to the scene. One of them put Soukaneh in an upright, seated position instead of where Andrzejewski had stuffed him, with his head near the floor. After another half hour, he was released. It is not clear if he was charged with a traffic violation.

SpaceX gets FCC okay for next Starship/Superheavy test flight

9:41 am

Superheavy being captured by the tower chopsticks at landing
Artist rendering of Superheavy being captured by
the tower chopsticks at landing. Click for video.

The FCC yesterday issued SpaceX a communications license for the fifth orbital test launch of its giant Starship/Superheavy rocket, with the license permitting Superheavy to “either return to the launch site or perform a controlled water landing.”

The license runs through February 15, 2025.

This does not mean a launch has been approved however. The FCC only gives approval for radio communications on such a flight. It is the FAA that must issue the actual launch license, and it as yet not done so.

SpaceX had announced on August 8, 2024 that it was ready to go. It is now almost two weks since then and the FAA has said nothing.

The only justifiable reason for this delay would be that SpaceX has requested permission to do the first chopstick landing of Superheavy at Boca Chica (as suggested by the FCC approval), and since this changes the already approved flight path from the previous four test launches, the FAA is reviewing it more closely, and taking its time to do so.

The simple fact is that it can’t learn anything by this review. It isn’t qualified to make any educated determination. Either it is willing to let SpaceX do that return, or not. If it is against it at this point, it should simply say so, demand SpaceX hold off a chopstick landing until later, and give it permission now to do another ocean landing. At least this way the company would have clarity and could proceed.

Rocket Factory Augsburg’s rocket fails during 9-engine static fire test

9:21 am

Screen capture of test failure
Screen capture from video of test failure.
Note the flame shooting out sideways.

During a static test yesterday of Rocket Factory Augsburg’s RFA-1 rocket, the first using all nine first stage engines, the rocket experienced what the company called an “anomaly” early in the test, causing a major fire and explosion.

The company’s statement also said the launchpad was “saved” and no one was injured.

I have embedded below a clip from a BBC video of the event. A company official had said only yesterday that it hoped to launch in a matter of weeks, though that official had given no word on whether the UK’s Civil Aviation Authority (CAA) had issued a launch license. I suspect he hoped this test would be successful and the CAA would then issue the license. That won’t happen now.

The test took place at the new commercial Saxavord spaceport in the Shetland Islands, which has also struggled in the past two years to get full licensing from the CAA. It has obtained those licenses, but it would not be surprising if this failure will cause the CAA — which appears very risk adverse — to reconsider its approvals.

Until this failure, Rocket Factory appeared to be in the lead among the new European rocket startups to complete its first launch. That now changes. The Spanish startup PLD hopes to launch from French Guiana in 2025, and is presently building its launchpad there. The UK startup Orbex also hopes to launch in 2025, but it wants to launch from the Sutherland spaceport in Scotland, has faced significant regulatory delays over the past two years from the CAA, and will now likely face further delays because of this failure. Another German startup, Hyimpulse, has already completed a suborbital test launch from Australia, but has not set a date for an orbital test. It originally hoped to launch from Saxavord in 2025, but has been looking for alternatives recently. Finally, the German startup Isar Aerospace has a deal to launch from the Andoya spaceport in Norway, but has announced no launch date.

SpaceX launches 20 more Starlink satellites using a new first stage

8:50 am

SpaceX early this morning successfully launched another 20 Starlink satellites, its Falcon 9 rocket lifting off from Cape Canaveral in Florida.

The first stage was new, having never flown before. It successfully landed on a drone ship in the Atlantic, and is now part of the company’s fleet of Falcon 9 first stages.

The leaders in the 2024 launch race:

83 SpaceX
34 China
10 Rocket Lab
9 Russia

American private enterprise now leads the rest of the world combined in successful launches 98 to 52, while SpaceX by itself now leads the entire world combined, including American companies, 83 to 67.

  • Rocket Factory Augsburg offical claims first orbital launch at Saxavord “only weeks away”

    • The claim is meaningless, in that neither he nor the article provide any update on the approval of a launch license by the UK’s Civil Aviation Authority (CAA). The company might be ready, but so was Virgin Orbit, and it was made to wait so long (an extra six months) by the CAA that it ran out of money and went bankrupt. I am willing to bet that this first launch will not happen this year.

 

 

  • Juno’s next close fly-by of Io this coming weekend

    • It won’t get as close as previous fly-bys, with this close approch only getting to within 27,218 miles away. Since Juno’s camera is not particularly high resolutoin, it will only be able to see objects bigger than 18 miles across.

Mining Mars

Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on May 22, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The picture’s focus of study is the bright strip running diagonally across the center, which the scientists label as a “linear feature exposure of infrared-bright material.”

This bright strip with all the swirls of alternating light and dark terrain is a fissure about 80 feet deep. What is interesting is that the parallel bright features to the north and south are actually ridges, not depressions, even though there appears to be some resemblance between them all. (Note that the patches of very thin parallel lines are likely ripple dunes sitting on top of the topography.)

So, what created this fissure? And why is its inner surface so strange? As is usually the case, a wider look provides some clues.

Pushback: Colorado has now been forced to lift its ban on visitors wearing clothing with political messages when they enter the gallery of the state legislature after it was threatened with a lawsuit for enforcing that ban arbitrarily and clearly favoring some political messages over others.

On March 31, 2023, Jeffrey Hunt came to that visiter gallery wearing a pro-life sweatshirt and was forced to leave by security, as described by the cease-and-desist letter sent to by Hunt’s lawyers.

Sergeant-At-Arms Ben Trujillo approached Hunt and instructed him to exit the gallery. Hunt complied. After leaving the gallery, Trujillo told Hunt that “Pro-Life U” was a “political statement” prohibited by a rule banning “pins or apparel expressing political statements”.

Yet, security had no problem with an entire group of demonstrators filling the gallery wear gun control shirts only two weeks earlier.

That letter, sent by the Foundation for Individual Rights and Expression (FIRE) on July 16, 2024, noted this unfair application of the rule. More importantly, it pointed out that the rule was a clear violation of the First Amendment. It demanded that the state cease enforcing this illegal law, or face a lawsuit.

Less than a month later, the state backed down, ending the rule.

Across the nation there have been numerous similar stories of security guard control freaks illegally censoring conservative speech. And in every case, when faced with legal action those venues have backed down every single time, proving the importance of fighting. See for example this story at the Smithsonian, or this story at the National Archives.

The news in space and science is very very slow today, so this short political news piece gets posted first, sent to me over the weekend by radio host Robert Pratt.

Sierra Space in negotiations to buy ULA

10:26 pm

According to the Reuters news agency, Sierra Space is negotiating with the joint owners of ULA, Boeing and Lockheed Martin, to buy the rocket company.

The sources, which are all anonymous, said the sale price is in the range of $2 to $3 billion. Those same sources said no deal has yet been worked out, and might not happen at all.

For Sierra, the deal would give it its own launch vehicle, Vulcan, for placing its Dream Chaser mini-shuttles into orbit. It would also give it a profit stream from the many military and commercial launch contracts already on ULA’s manifest. The combined cababilities of ULA and Sierra will create a formidable new player in the aerospace launch market.

For Boeing, it would provide it some much needed cash that it will be able to use to both restructure and revitalize its presently questionable operations.

It is unclear what Lockheed Martin will gain from the sale, other than the cash and the removal of this Frankenstein-like partnership with Boeing, which in the long run has probably not done it a lot of good.

SpaceX launches 116 payloads on its eleventh smallsat Transporter mission

12:20 pm

SpaceX today successfully launched 116 payloads, including 108 satellites, on its eleventh smallsat Transporter mission, its Falcon 9 rocket lifting off from Vandenberg in California.

The first stage completed its twelfth flight, landing back at Vandenberg. As of posting the satellites had not deployed.

The payloads included a wide variety of satellites and demonstration missions, including one orbital tug from the European tug company D-Orbit, its Ion tug deploying five satellites. In addition, five different companies will be using their own deployment equipment to release about fifty of the satellites from the Falcon 9.

These SpaceX Transporter smallsat launches demonstrate the value of lowering the cost to launch. Almost none of these satellites could have obtained investment capital when the cost high. Now that SpaceX has lowered that cost, a plethora of new satellite companies of all kinds can get that capital and build and launch their projects. And that burst of new companies is more than enough to provide business not only to SpaceX but to a lot of other new rocket startups.

The leaders in the 2024 launch race:

82 SpaceX
34 China
10 Rocket Lab
9 Russia

American private enterprise now leads the rest of the world combined in successful launches 97 to 52, while SpaceX by itself still leads the entire world combined, including American companies, 82 to 67.
