NASA/Boeing: Cause of Starliner thruster failure identified

10:21 am

According to NASA and Boeing officials, ground static fire engine tests have now identified the likely cause of the thruster failures on the Starliner capsule during its docking to ISS in early June, and puts them in a position next week to determine a return date for the capsule and its two astronauts.

It appears the problem is related to teflon seals in the thrusters, detected while engineers did a series of tests on the ground with another Starliner capsule. Based on this information, Boeing thinks it can fix the problem on future capsules, while also insuring there will be no problems returning the astronauts from ISS.

The thrusters in question are all attitude thrusters, where there is a lot of redundancy and the issue has been seen to be well controlled from the start. The larger thrusters used for the undocking and de-orbit burn have been tested as well, and have not shown any similar issues at all.

The ground tests have also identified the cause of the helium leaks within the capsule engine system. Boeing will use this data to fix later capsules as well. These leaks are not a concern for the return to Earth.

The plan now is to do in the next few days one more set of static fire tests with the capsule docked on ISS, doing short bursts with all the attitude thrusters to further confirm what has been learned on the ground. If that goes as expected, a final meeting next week will determine the return date for the capsule and crew.

Hungary/Axiom finalize deal to fly a passenger on its AX-4 commercial manned mission to ISS

9:52 am

Hungary and Axiom have finalized their agreement to fly 32-year-old mechanical engineer Tibor Kapu on Axiom’s AX-4 commercial manned mission to ISS, presently targeting an October 2024 launch date.

That flight will use a Dragon capsule and last 14 days. Kapu would be the second Hungarian to ever fly in space, following Bertalan Farkas’s eight day mission in 1980 in a Soyuz capsule during the Soviet era.

Hungary and Axiom had worked out an initial agreement in 2022, with the country to pay the company $100 million for the flight. At that time the flight was to last 30 days, not two weeks. It was also unclear if the mission would be free-flying or dock with ISS, or even whether it would fly on a Dragon or Starliner capsule. There is no word on how these changes have impacted the price.

Saxavord: We will get our last required spaceport license by September

11:45 pm

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea.

My heart be still: According to one official of the Saxavord spaceport in the Shetland Islands, it expects to get its last required spaceport license from the Civil Aviation Authority (CAA) of the United Kingdom sometime in September of this year.

In a presentation at the Farnborough International Airshow here July 23, Scott Hammond, deputy chief executive and operations director of SaxaVord Spaceport, said he expected the spaceport to receive the last of the licenses from U.K. regulators in September needed to host the inaugural launch of Rocket Factory Augsburg’s RFA ONE rocket there.

The red tape getting the first launch off at Saxavord has been odious and disheartening, to say the least. After almost two years of deliberations, the CAA awarded the spaceport its spaceport license in December 2023. This finally allowed it to be a spaceport, but apparently that was insufficient for it to be allowed to do any launches. The CAA then took three more months to issue what it called the range license.

Saxavord was still not allowed to do any launches. The CAA demanded one more license for what it calls “airspace access for launches.” I have no idea how this is different than the range license, unless the CAA has separated control of the surface from the air space, and thus requires two separate licenses for each. Either way, getting that approved has now dragged on for months. No one should be confident Saxavord’s September prediction for approval will turn out to be true.

All these licenses however will still not permit any launches to proceed. The CAA also requires each particular rocket company to get its own launch license. Though Saxavord as well as Rocket Factory are targeting a launch before the end of the year, soon after getting that last airspace license, they might be counting their chickens before they hatch, based on the CAA’s track record with Virgin Orbit.

After Cornwall got all its CAA licenses to allow Virgin Orbit to launch from that airport, Virgin thought it would be able to get is launch license quickly and launch within only a few months. Instead, the CAA took about a year to issue Virgin its launch license, with that long delay eventually becoming the main reason the company went bankrupt.

Rocket Factory unfortunately appears to have locked itself into Saxavord. It has already done a static fire test of its first stage there, and has delivered the rocket’s upper stage. If the CAA takes its time again giving its approval, the startup might find itself bleeding cash, as Virgin Orbit did.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

The anti-Semitic Pro-Hamas Democratic Party shows its colors again

5:17 pm

Democrats burn American flags in support of Hamas
Democrats burn American flags in support of Hamas

Today the prime minister of Israel, Benjamin Netanyahu, came to Washington to meet with American government officials and give a speech before both houses of Congress.

Not surprisingly, numerous Democrats both inside and outside Congress showed their hatred of Israel and love of the Hamas terrorists, enthusiastically slandering Netanyahu, Israel, and its struggle to survive while elevating terrorists into “freedom fighters”, even though on October 7 last year those Hamas fighters weren’t fighting for freedom, they were out to kill Jews, eagerly raping, torturing, and murdering more than a thousand men, women, children, and babies simply because they were present inside Israel.

Inside Congress more than forty Democrats boycotted Netanyahu’s speech, including Vice President Kamala Harris (now running for president against Trump). Apparently Harris is courting the American Hamas voting block. Democrats who did attend made it clear in numerous ways that they oppose the right of Israel and Jews to exist and that they support Hamas’ murder of women, children and babies, though of course they couched their statements in cute ways filled with lies in order to give themselves plausible deniability. For example, Nancy Pelosi said this:

The mountains of Mars

Curiosity's view south July 24, 2024
Click for full resolution. For original images go here and here.

Overview map
Click for interactive map.

Cool image time! The panorama above, created from two left navigation camera photos taken by the Mars rover Curiosity on July 24, 2024 (here and here), looks south up the flanks of Mount Sharp as well as into the Gediz Vallis channel that the rover has been exploring for the past year or so.

The overview map to the right provides us a wide view of Gale Crater and the rover’s entire journey there since it landed on Mars in 2012. The blue dot marks its present position. The yellow lines indicate the approximate view in the panorama above. The red line indicates the planned route, leaving Gediz Vallis to take a parallel canyon uphill to the west.

Curiosity during its dozen years on Mars has traveled just under 20 miles and climbed about 2,500 feet. The peak of Mount Sharp however is still about 26 miles away and about 16,000 feet higher.

The rover is now at the very base of the sulfate-bearing unit, which is why last month it literally ran over some rocks that were its first detection of pure sulfur crystals on Mars. Once Curiosity reaches that sulfate-bearing unit it is likely going to be an extremely alien landscape, comprised of rock that is suffused everywhere with sulfur. Such landscapes are likely impossible on Earth due to its oxygen-rich atmosphere. The sulfur and oxygen would interact, forming different molecules.

Judge issues injunction against NLRB in favor of SpaceX

10:34 am

NLRB logo

A U.S. federal district judge today issued an injunction against the National Labor Relations Board (NLRB), blocking any further action on its complaint against SpaceX until the courts rule on the constitutionality of that complaint, accepting SpaceX’s position that the NLRB’s decision to suspend that complaint pending a court decision was irrelevant.

The NLRB has sued SpaceX, claiming it had violated the labor rights of several former employees because it fired them for criticizing Musk publicly. SpaceX responded by suing the NLRB itself, claiming the law which founded it and allowed it to act as prosecutor, judge, and jury in all cases while also limiting the President’s ability to fire its officials was unconstitutional.

As the case moved through the courts, the NLRB suspended its case against SpaceX. The company however demanded this injunction as well, since it considered that suspension merely a ploy that could be rescinded at any time.

Judge Albright ruled in favor of SpaceX and imposed an injunction as the case proceeds. He said the ruling came in part because of the U.S. Court of Appeals for the Fifth Circuit’s ruling that restrictions on removal for administrative law judges in the Securities and Exchange Commission are unconstitutional.

You can read the judge’s decision here [pdf]. This quote from it however is very telling:

Webb takes infrared image of exoplanet

A Jupiter-sized exoplanet imaged by Webb
Click for original image.

Cool image time! Using the Webb Space Telescope, scientists have taken an infrared false color image of a multi-Jupiter-sized exoplanet located only twelve light years away and orbiting the K-type star Epsilon Indi A.

That picture, cropped, reduced, and sharpened to post here, is to the right. The light of the star, indicated by the star symbol, has been blocked by Webb’s coronagraph, the size of which is shown by the dashed circle. The exoplanet is the orange blob to the left.

[This exoplanet] is one of the coldest exoplanets to be directly detected, with an estimated temperature of 35 degrees Fahrenheit (2 degrees Celsius) — colder than any other imaged planet beyond our solar system, and colder than all but one free-floating brown dwarf. The planet is only around 180 degrees Fahrenheit (100 degrees Celsius) warmer than gas giants in our solar system. This provides a rare opportunity for astronomers to study the atmospheric composition of true solar system analogs.

The data also revealed that the exoplanet is twice as massive as expected and has a slightly different orbit than expected based on previous less precise data.

SpaceX’s contract to de-orbit ISS reveals the inability of the older space companies to compete

9:49 am

Link here. The article goes into detail about the bidding process that led to SpaceX winning the contract $843 million fixed-price contract to build a specialized Dragon capsule to dock with ISS and de-orbit it. While its focus is on the refusal of the older companies (Northrop Grumman, Lockheed Martin, and Boeing) to sign the fixed-price contracts that NASA now prefers and that SpaceX can handle with no problem, it was this section that struck me the most:

SpaceX’s bid price was $680 million. The source selection statement did not reveal a price for Northrop’s bid other than saying it was “significantly higher.” Based on NASA’s budget request, Northrop’s bid was likely approximately twice as high.

But SpaceX did not just win on price. Its “mission suitability” score, effectively its technical ability to design, develop, and fly a vehicle capable of deorbiting the space station, was 822, compared to Northrop’s score of 589. SpaceX’s approach had one weakness, compared to seven weaknesses in Northrop’s bid, according to NASA evaluators.

Finally, the selection was also based on past performance by the contractors. SpaceX’s performance was rated as “very high,” given how it has delivered with the Cargo and Crew Dragon spacecraft and its Falcon 9 rocket. Northrop’s performance on Cygnus and its various rockets was given a “moderate” rating. Overall, the NASA evaluators expressed a “very high level” of confidence in SpaceX being able to complete the mission, whereas a “moderate level” of confidence was expressed in Northrop.

In other words, Northrop not only couldn’t do the job as cheaply and wasn’t even willing to do it at a fixed price, its technical performance has not been that good either.

The article focuses rightly on the present lack of any viable competitors to SpaceX, and the problems this raises for the entire American aerospace industry. I want to point out how this situation reveals a much more fundamental problem with the industry itself. The established aerospace industry is not only doing poor work, it is overcharging for it.

Or to put it more bluntly, it is unwilling or unable to compete. Relying on businesses with such bankrupt attitudes is not a good way to get anything done.

The hope had been that the newer startups (Rocket Lab, Blue Origin, Relativity, Firefly, etc) would pick up this slack, but except for Blue Origin the rocket capabilities of these companies are just not big enough yet to do it. Blue Origin’s proposed New Glenn rocket and associated spacecraft could do the job, but the company has demonstrated for the past decade its desire to emulate the older and failing big space companies rather than a new fresh face.

The new companies, given time, could solve this problem, since they are all willing to innovate and compete, but the apparent increase in the regulations imposed by the FAA and other government agencies in the past two years suggests they will be squelched as well.

Unless something changes, the U.S. is not going to see the space renaissance that seemed so promising only two years ago.

Axiom hires British astronaut Tim Peake

9:32 am

Axiom has now added British astronaut Tim Peake to its staff, making him the fourth astronaut after Michael Lopez-Alegria, Peggy Whitson, and Koichi Wakata working for the commercial space station and space tourism company.

The decision appears to be in connection with Axiom’s agreement with the UK Space Agency to fly an all-British manned commercial mission in exchange for $19 million in government funding. NASA regulations require any commercial mission that docks with ISS to include as a company commander an experienced astronaut. By hiring Peake Axiom fulfills this requirement.

No date for this four-person two week mission to ISS has been announced. Nor have any other passengers been named. It is very possible this announcement today is a PR effort by Axiom to drum up interest from potential British customers because the earlier announcements have possibly failed to do so.

Scientists find hydrogen molecules in Chang’e-5 lunar samples

9:18 am

According to China’s state-run press, scientists analyzing the lunar samples brought back by its Chang’e-5 lander have detected extensive “hydrated” molecules in Moon’s regolith.

The mineral’s structure and composition bear a striking resemblance to a mineral found near volcanoes on Earth. At the same time, terrestrial contamination or rocket exhaust has been ruled out as the origin of this hydrate, according to the study.

The Chinese article keeps referring to these molecules as a form of “water molecules” but that is dead wrong. These are mineral molecules that simply have hydrogen as a component. There is no water here.

The discovery suggests that the detection of hydrogen on the surface of the Moon, both in the permanently-shadowed craters at the poles as well as lower latitudes, might not be water at all, but hydrated minerals. If so, the Moon is going to be a much more difficult place to establish colonies or even research bases, as getting water (and hydrogen and oxygen) is going to require a much more difficult mining and processing effort.

For several years the data has increasingly pointed in this direction. And for several years I have noticed a strong unwillingness of scientists and the press to recognize the trend (as illustrated by the above article’s false insistence that these are water molecules). Water ice has not been ruled out yet in the permanently-shadowed craters at the poles, but the evidence is mounting against it.

I suspect this reluctance is fueled by a desire to not say anything that might discourage exploration of the Moon, and the possibility of water there has been the main driver for all the recent lunar exploration programs. I can’t play that game. As much as I want humanity to explore the Moon and the solar system, we mustn’t do it based on lies. The facts need to be reported coldly.

Everything connected to Washington and the Democratic Party stinks like a rotting corpse

1:00 pm

I didn’t post an essay yesterday because I could not figure out what to write. The insanity of the past week, with Trump’s near assassination, the horrendous incompetence of the Secret Service, the sudden disappearance of Joe Biden, and then his somewhat mysterious withdrawal from the candidacy of the presidency, all presented too many topics that were changing too fast to digest.

Vultures eating carrion

All I can now take from these events is an impression of a rotting corpse, the Democratic Party, that the voters should have buried decades ago. Instead, the voters have propped it up, allowing its stink to spread until it has poisoned everything related to American government and the noble but now dying principles that formed it.

For example, it now appears that the colossal security failure on July 13th during Trump’s Pennsylvania rally was the result of providing the Secret Service too few resources, forcing it to depend more on local authorities than normal. The Secret Service and the local police then showed themselves to all be utterly incompetent. It appears communications between these different government agencies was poor or non-existent. The local people were supposed to secure the top of the roof where the assassin eventually placed himself, but decided instead to go inside the building because the roof “was too hot.”

Unfortunately, it seems this decision wasn’t conveyed to the Secret Service properly. It therefore appears Crooks was able to station himself on the roof and fire at Trump because the Secret Service thought he was a local police sniper.

At least, that’s my interpretation of the facts, as presently understood. » Read more

More great hiking on Mars

More great hiking on Mars
Click for original image.

Today’s cool image takes us to another place on Mars where future colonizers will find the hiking breath-taking. The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on April 18, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The camera team labeled it merely as a “terrain sample,” indicating it was not taken as part of any specific research project request, but to fill a gap in the schedule in order to maintain the camera’s proper temperature. When the MRO team does this, they try to pick interesting sites, sometimes successfully, sometimes not.

In this case the image captured the sharp nose of a 2,100-foot-high mesa which to my eye immedately said, “I want to hike a trail that switchbacks up that nose!” Ideally, the trail would then skirt the edge of the mesa, then head up to the top of that small knoll on the plateau. Though only another 200 feet higher or so, the peak would provide an amazing 360 degree view of the surrounding terrrain.

New collection of X-ray false-color Chandra images

9:30 am

Chandra image of galaxy
Click for original image.

Cool image time! As part of a PR campaign by NASA to convince Congress to give it more money to keep the Chandra X-ray Observatory funded, the agency this week released twenty-five new images, supposedly to celebrate the space telescope’s 25th anniversary since launch.

It must be emphasized that these photos are not solely produced by Chandra. They combine its X-ray data wth optical data from Hubble and infrared data from a number of other telescopes.

The picture to the right is of the galaxy NGC 6872 that is interacting with its nearby smaller neighbor. From the caption:

NGC 6872 is 522,000 light-years across, making it more than five times the size of the Milky Way galaxy; in 2013, astronomers from the United States, Chile, and Brazil found it to be the largest-known spiral galaxy, based on archival data from NASA’s Galaxy Evolution Explorer. This record was surpassed by NGC 262, a galaxy that measures 1.3 million light-years in diameter.

Chandra will get its funding to continue operations. NASA is simply playing its old game of bluff with Congress to force it to give the agency a boost in funding. Like a toddler throwing a tantrum, it cancels a successful project, citing funding shortages (even though those shortages are almost always because of mismanagement elsewhere in the agency), and Congress eventually gives in like a weak parent, raising NASA’s budget.

The big image release this week is part of that game. Nonetheless, the images are spectacular, and loaded with new information not otherwise available without Chandra’s X-ray capabilities. If Congress had any spine, it would force NASA to fully fund such successful projects and simply delete the failed ones (such as SLS and Mars Sample Return). It has no spine, however, and thus we have a national debt in the trillions that is bankrupting us.

Russia releases timeline for its Russian Orbital Station to replace its ISS operations

9:03 am

Tabletop Model of Russian Space Station
A tabletop model of the station unveiled in 2022

Earlier this month Russia released a detailed timeline for the construction of its Russian Orbital Station (ROS) to replace its ISS operations once the older station is retired and de-orbited, with the first station module supposedly launched in 2027 and the station completed by 2033.

Russia is set to launch the future orbital outpost’s first research and energy module in 2027, Roscosmos said. Roscosmos also plans to launch the universal nodal, gateway and baseline modules by 2030 to form the core orbital station together with the research and energy module, it said. “At the second stage, from 2031 to 2033, the station is set to expand by docking two special-purpose modules (TsM1 and TsM2),” Roscosmos said.

The project is estimated at 608.9 billion rubles (about $6.98 billion).

This project has been discussed in Russia since the middle of the last decade, and as usual for Russian government-run space projects, it has limped along with little but powerpoint proposals and small demo models (as shown on the right) for years. The impending end of ISS and its replacement by commercial stations (that will not include any Russian participation) seems to have finally helped get the project started for real.

Don’t expect this above schedule however to meet its target dates. Russia’s track record since the fall of the Soviet Union is that such projects usually take two decades to launch, not three years.

Astroscale wins contract to deorbit OneWeb satellite

8:50 am

The orbital tug company Astroscale has won a $15 million contract from both the UK and European space agencies to launch a mission to rendezvous, grab and then deorbit a defunct OneWeb communications satellite.

The company, originally from Japan, has established operations in both the U.S. and Europe in order to win contracts from those regions, and had already signed contracts with OneWeb, several UK companies, the the European Space Agency (ESA), and the UK Space Agency for this project. This new contract apparently releases the money from both ESA and the UK.

The mission, dubbed ELSA-M, is will fly no later than April 2026, will be built by Astroscale’s UK division in Oxford, and is a follow-up of the ELSA-d mission that in 2021 demonstrated rendezvous and proximity operations but was unable to complete a docking using Astroscale’s magnetic capture system because of failed thrusters. I suspect the reason this new deal was finally approved is because of Astroscale’s more recent successes in another mission for Japan’s JAXA space agency, ADRAS-J, rendezvousing and flying in proximity to an old abandoned H2A rocket upper stage.

The new mission will attempt once again to prove the practicality of Astroscale’s magnetic capture system, which it is trying to convince all satellite companies to include on their satellites.

UK distributes cash to space sector to keep them in the UK

12:23 pm

The United Kingdom government today announced five different grants totalling $14 million to various institutions and companies in an effort to promote aerospace operations within the UK.

The biggest grant, $6.45 million, went to the German rocket startup Hyimpulse to help pay the cost of a vertical launch of its SR75 test suborbital rocket from the Saxavord spaceport in the Shetland Islands.

Hyimpulse, which had originally planned to do its test launches from Saxavord, had been forced to do its first launch from the Southern Launch spaceport in Australia because of regulatory delays in the UK. Because of that red tape the company also signed a further agreement with that Australian spaceport for future test flights. It appears this grant is the UK government effort to get Hyimpulse launches back.

Nor is this the first such grant to Hyimpulse, or to a German rocket startup. Previously Hyimpulse had won two grants totaling almost $5 million. In addition, the UK has also awarded the German rocket startup Rocket Factory Augsburg just under $5 million.

Of the other four grants in this most recent award, the second biggest ($4.57 million) went to a Glasgow company, Spire Global, to develop better weather satellite forecasting technologies. The other three grants were all about a million dollars each, and went a variety of space sector institutions/companies in Scotland.

It is apparent that the red tape problems at Saxavord that has been driving rocket startups away from the UK has forced the UK government to reach into its wallet to try to keep them from leaving. For these companies, taking the money is a two-edge sword. The cash is nice, but if they can’t launch as planned it does them little good. I expect these deals require Hyimpulse and Rocket Factory to launch from Saxavord, but do not require them to do so first. This gives these companies the freedom to go elsewhere if necessary to meet their schedules.

A classic spiral galaxy

A classic spiral galaxy
Click for original image.

Monday is always a slow news day in space, so we start the day with a cool image. The picture to the right, reduced and sharpened to post here, was taken by the Hubble Space Telescope of a spiral galaxy about 100 million light years from Earth.

That NGC 3430 is such a fine example of a galactic spiral may be why it ended up as part of the sample that Edwin Hubble used to define his classification of galaxies. Namesake of the Hubble Space Telescope, in 1926 he authored a paper which classified some four hundred galaxies by their appearance — as either spiral, barred spiral, lenticular, elliptical or irregular. This straightforward typology proved immensely influential, and the modern, more detailed schemes that astronomers use today are still based on it. NGC 3430 itself is an SAc galaxy, a spiral lacking a central bar with open, clearly-defined arms.

The bright blue indicates areas of star formation, while the reddish streaks indicates dust. The orange/reddish dots above and below the galaxy are distant background galaxies whose light has been shifted to the red because they appear to be moving away from us due to the expansion rate of the universe.

NASA suspends all U.S. spacewalks on ISS due to water leak

9:03 am

Because of a water leak that occurred in an umblical cord at the beginning of a spacewalk on June 24, 2024, NASA has now suspended all U.S. spacewalks on ISS as it investigates the cause.

Tracy Dyson, a NASA astronaut, had a brief spacesuit leak a month ago while still in the hatch of the International Space Station (ISS). She and Mike Barrett had just opened the door for a 6.5-hour spacewalk for maintenance activities, when showers of ice particles erupted from a spacesuit connection to the ISS. The spacewalk was suspended, but the astronauts were never in any danger, NASA has emphasized.

“That spacewalk ended early because of a water leak in the suit’s service and cooling umbilical; that’s the site that’s connected to ISS,” station program manager Dana Weigel, of NASA, told reporters in a teleconference Wednesday (July 17). (Astronaut spacesuits stay connected to ISS life support systems via that umbilical until just before they exit the hatch.) “We’re still taking a look at the cause of the water leak, and what we want to do to recover,” Weigel added. “We’ll go look for the next opportunity for where we want to do the spacewalk. It’s not time-critical or urgent, and so we’ll find the best, logical place to put it.”

At this moment NASA has still not identified the cause of the leak, though astronauts on ISS have been inspecting the umblical cord as well as the entire suit, disassembling components where possible.

What really needs to happen is the delivery of newly designed suits, something NASA has wanted done for about fifteen years. The agency spent most of that time making powerpoint presentations and spending a billion dollars, with no new suits produced. It is now hoping its spacesuit contract with Axiom will get it new spacesuits.

The Trump assassination attempt provides another illustration of our bankrupt press/media

3:11 pm

We can learn a lot about the press by watching how they react to breaking news stories, with the aftermath and questions about the Secret Service’s actions during the attempt on Donald Trump’s life on July 13, 2024 being a perfect example.

My goal is not to analyze the failures of the Secret Service that day. Others will do that far better than I. My goal here is to analyze the press itself, to illustrate who is really interested in finding out what really happened, to report the news, and who is not.
