Musk: European Union attempted to blackmail X into censoring tweets
The EU to Elon Musk: “Nice company you got here.
Shame if something happened to it..”
Almost immediately after the European Union announced today that it considered X in violation of its Digital Services Act (DSA), claiming that the social media company owned by Elon Musk was breaking the act “in areas linked to dark patterns, advertising transparency and data access for researchers,” Elon Musk responded most bluntly in a tweet:
The European Commission offered 𝕏 an illegal secret deal: if we quietly censored speech without telling anyone, they would not fine us.
The other platforms accepted that deal.
𝕏 did not.
In other words, the EU tried to blackmail X and Musk into censoring some users of X, based on criteria that EU chose. When X refused to play that game, the EU followed through with today’s announcement, threatening the following if Musk does not kow-tow:

FAA is apparently starting a new environmental impact assessment for Boca Chica
Damaged but working flap during June 6, 2024
Starship/Superheavy test flight
Today I received the following email from the FAA:
Dear Interested Party:
The FAA is holding public meetings on the Draft Tiered Environmental Assessment (Draft EA) for SpaceX’s proposal to increase the number of launches and landings of its Starship/Super Heavy vehicle at the Boca Chica Launch Site in Cameron County, Texas. The Draft EA will analyze SpaceX’s proposal to increase its launch and landing cadence as follows:
- Up to 25 annual Starship/Super Heavy orbital launches
- Up to 25 annual landings of Starship
- Up to 25 annual landings of Super Heavy
The Draft EA will also address vehicle upgrades.
There will be three public meetings, one on August 13, 2024 on South Padre Island, one on August 15, 2024 in Port Isabel, and the third a virtual zoom meeting on August 20, 2024. Anyone can register for the zoom meeting. For all the meetings, “The public will have an opportunity to submit written and oral comments during the meetings.” Expect the leftist anti-Musk, anti-SpaceX activists to come out in droves.
What is really significant about this is that SpaceX has applied to expand its operations at Boca Chica beyond the limitations set by the environmental reassessment issued in 2022. The FAA had said in that reassessment it would re-open it if and when SpaceX requested any changes. It has now done so.

A penguin and egg, as seen by Webb and Hubble
Click for original images.
Cool image time! The two pictures to the right, cropped, reduced, and sharpened to post here, were taken by both the Webb and Hubble space telescopes of the same unusual galactic object, officially called Arp 142 but nicknamed by astronomers the Penquin and the Egg.
Both of these objects are galaxies. The Penquin’s strange shape is caused by the presence of the Egg, which is an elliptical galaxy that is twisting and distorting the Penquin’s original spiral galaxy whirlpool as it flies past. From the caption:
Like all spiral galaxies, the Penguin is still very rich in gas and dust. The galaxies’ “dance” gravitationally pulled on the Penguin’s thinner areas of gas and dust, causing them to crash in waves and form stars. Look for those areas in two places: what looks like a fish in its “beak” and the “feathers” in its “tail.”
Surrounding these newer stars is smoke-like material that includes carbon-containing molecules, known as polycyclic aromatic hydrocarbons, which Webb is exceptional at detecting. Dust, seen as fainter, deeper orange arcs also swoops from its beak to tail feathers.
In contrast, the Egg’s compact shape remains largely unchanged. As an elliptical galaxy, it is filled with aging stars, and has a lot less gas and dust that can be pulled away to form new stars. If both were spiral galaxies, each would end the first “twist” with new star formation and twirling curls, known as tidal tails.
Another reason for the Egg’s undisturbed appearance: These galaxies have approximately the same mass or heft, which is why the smaller-looking elliptical wasn’t consumed or distorted by the Penguin.
The differences between the two pictures also reveal many aspects of the Penguin. The Hubble optical image at the top captures the lanes of dust in the foreground, while the Webb infrared image at the bottom looks right through this dust to better trace the now-distorted spiral arms where star formation is presently taking place.
Astronomers estimate that these two galaxies are about 100,000 light years apart, comparable to the width of the Milky Way. In comparison, the Andromeda galaxy is around 2.5 million light years away, and will not begin interacting with our galaxy in this manner for an estimated four billion years. The Egg and Penguin however began their warped dance about 50 million years ago.
Russia arrests three Europeans this week for trespassing at Baikonur spaceport
Russia this week arrested three Europeans, two Dutch and one Belgium, for sneaking onto the Baikonur spaceport in Kazakhstan illegally.
This is the second time this year and the third time since 2022 that Russia has caught Europeans attempting to enter the spaceport illegally. In June one of those trespassers died in the attempt from dehydration. It appears it has become “a thing” to do, mostly by social media types who then post videos of their travels.
Russia and Kazakhstan however invite these trespasses because neither makes it easy or even possible to visit the spaceport and see its sights. Its inavailabiity makes it a target, and thus these illegal visits. It would be much better is both countries routinely ran public tours, at very reasonable rates, as NASA does at Cape Canaveral. India’s space agency ISRO meanwhile makes money by selling tickets to view its launches.
China planning an asteroid collision mission similar to DART
It appears China is putting together an asteroid collision mission similar to NASA 2022 DART mission that impacted the asteroid Dimorphus.
The China National Space Administration (CNSA) mission may have already selected its target — the near-Earth object (NEO) 2015 XF261, a nearly 100-foot-wide (30 meters) asteroid.
According to the small-body database managed by NASA’s Jet Propulsion Laboratory (JPL), 2015 XF261 last came relatively close to Earth just this week, on Tuesday (July 9), when it passed within 31 million miles (50 million kilometers) of our planet. The space rock was traveling at around 26,000 mph (42,000 kph), roughly 30 times faster than the speed of sound.
Much of the information about this proposed comes from a very detailed a Planetary Society report, which said that the mission is targeting a 2027 launch and described the mission as follows:
The plan is for the observer spacecraft to reach the target asteroid first and conduct three to six months of close and orbiting observations to study the asteroid’s size, shape, composition, and orbit. Then the impactor spacecraft will perform a high-speed kinetic energy impact test with the target asteroid. The observer will monitor the entire impact process and evaluate the aftermath for 6-12 months to ascertain the effects.
As with DART, the claim is that this mission is primarily focused on planetary defense (learning how to prevent asteroid impacts of Earth). That claim however is bogus. While that component of the mission exists, it is not the primary purpose, which is to study asteroids themselves.
South Korea: Numerous close calls between its lunar orbiter and others
A South Korean official has revealed that during the ongoing mission of its lunar orbiter Danuri it has had to act to avoid dozens of potential collisions with three other spacecraft.
In a presentation at the Secure World Foundation’s Summit for Space Sustainability here July 11, Soyoung Chung, senior researcher at the Korea Aerospace Research Institute’s (KARI’s) strategy and planning directorate, said her agency had received 40 “red alarms” of potential collisions among spacecraft orbiting the moon in the last 18 months.
The warnings primarily involve close approaches involving KARI’s Korea Pathfinder Lunar Orbiter (KPLO), NASA’s Lunar Reconnaissance Orbiter (LRO) and the Chandrayaan-2 orbiter from India’s space agency ISRO, which are all in similar low orbits around the moon. The three agencies voluntarily share information about the orbits of their spacecraft using a NASA platform called MADCAP that generates collision warnings.
In addition, engineers had to institute a maneuver to avoid Japan’s SLIM lunar lander, and in that case the warning occurred only a day before the potential collision was to occur.
The official noted that at present there is no system to coordinate lunar orbits and spacecraft, as exists for Earth orbit. South Korea and Romania have proposed giving this power to the United Nations Committee on the Peaceful Uses of Outer Space, which based on UN politics would likely be a very bad thing for the commercial space industry. I guarantee that UN agency would quickly favor government missions in its decision, and would also favor authoritarian governments over capitalist nations.
Spanish rocket startup PLD gets $34 million loan to build orbital rocket
The Spanish rocket startup PLD has obtained a $34 million bank loan to build its Miura-5 orbital rocket.
On 12 July, PLD Space announced that it had received a €31.2 million syndicated loan from Banco Santander, EBN Banco, and the Instituto de Crédito Oficial. A syndicated loan is provided by a group of lenders to distribute the financial risk among the participating lenders.
…According to the company, the loan amount will primarily be used for the Miura 5 rocket development programme, which includes both the development of the rocket and the expansion of the company’s industrial capabilities. It will also be used to support the company’s growth, with PLD planning to surpass 300 employees by the end of 2024.
For a rocket startup to get significant financing through a bank loan like this is very unusual. Almost always banks are reluctant to loan money for such a risky project. Instead, rocket startups get investment capital from venture capitalists, who are willing to take greater risks. PLD itself has already raised $164 million in this manner, $46 million of which came from the Spanish government itself.
I therefore wonder if some political pressure from the Spanish government helped convince the banks to approve the loan.
Regardless, PLD hopes to do the first orbital test launch of Miura-5 in 2025, with operational flights to follow the next year.
Europa Clipper mission threatened by faulty transistors
Engineers have learned that transistors installed on NASA’s Europa Clipper mission were not built to the right specifications and could fail in the harsh environment surrounding Jupiter.
The issue with the transistors came to light in May when the mission team was advised that similar parts were failing at lower radiation doses than expected. In June 2024, an industry alert was sent out to notify users of this issue. The manufacturer is working with the mission team to support ongoing radiation test and analysis efforts in order to better understand the risk of using these parts on the Europa Clipper spacecraft.
Testing data obtained so far indicates some transistors are likely to fail in the high-radiation environment near Jupiter and its moon Europa because the parts are not as radiation resistant as expected. The team is working to determine how many transistors may be susceptible and how they will perform in-flight. NASA is evaluating options for maximizing the transistors’ longevity in the Jupiter system. A preliminary analysis is expected to be complete in late July.
This issue could be disaster for the mission, which has a launch window that opens on October 10, 2024. If it is impossible to replace the bad transistors, NASA will be faced with two choices, neither great. It could launch regardless and hope for the best. It could delay the mission to fix the problem, which might involve a delay of years waiting for a new launch window.
This story appears to illustrate once again the decline in quality control that appears to be happening across much of American industry. The technology for building radiation-hardened equipment has been standard for decades. For a company to deliver equipment below standard now suggests incompetence or fraud, neither of which speaks well for it and the entire industry.
SpaceX launch experiences a failure of upper stage
For the first time since June 2015, a SpaceX Falcon 9 launch experienced a failure today after lifting from Vandenberg in California. During a launch tonight of twenty Starlink satellites, the upper stage showed signs of a fuel leak during its initial burn, and according to a tweet from Elon Musk, it exploded when it relit to make a final orbital adjustment.
Upper stage restart to raise perigee resulted in an engine RUD [rapid unscheduled dissembly] for reasons currently unknown. Team is reviewing data tonight to understand root cause.
Starlink satellites were deployed, but the perigee may be too low for them to raise orbit. Will know more in a few hours.
The arrow on the screen capture from the live feed, taken during the upper stage’s initial burn, indicates that apparent leak.
The first stage however successfully completed its nineteenth flight, landing on a drone ship in the Pacific.
This failure ended an incredible string of 344 successful launches, a record unmatched by any rocket ever in the history of space exploration. It was also the very first launch failure of SpaceX’s Block 5 Falcon 9, the rocket’s final design that has allowed the first stages to be reused now more than twenty times.
The next SpaceX launch is presently scheduled for July 14, 2024, but we should expect that launch to be postponed while engineers investigate the failure tonight. We should also expect that delay to last no more than several weeks, at most.
Archeologists find the musket balls fired in the first shots of the Revolutionary War
Archeologists digging at Concord discover what they think are five musket balls fired in the first shots of the Revolutionary War.
Archeologists believe five musket balls unearthed in Concord’s Minute Man National Historical Park were fired by colonial militia in the famed battle moments that sparked the Revolutionary War. The 250-year-old musket balls were discovered in an area inside the park where historians believe British troops faced colonial forces at the North Bridge.
Analysis of the artifacts indicates they were fired by colonial militia members from across the river, and not dropped from British weapons when troops were reloading.
Since the Minute Men fired over a period of time, routing the British troops, there is no way to know if these musket balls were the first fired, or among the later rounds. Nonetheless, these artifacts are an actual piece of a moment of history that literally changed all of human history.

A ridge that runs right over a Martian mesa
Click for original image.
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on April 5, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). I have cropped it to focus on the geological feature that likely attracted the interest of the scientists who requested this photo, the mesa that has a ridgeline running over it as if the mesa was not even there.
The mesa is about 80 feet high on its west side, but on its east the ground continues to drop away more than 500 feet as you move 2.5 miles to the east. Based on how the MRO science team interprets the colors [pdf] in the color strip, the orange areas are likely dust while the greenish surface suggests coarser sand and boulders. This conclusion is reinforced if you look at the parallel dunes south of the mesa. The dunes are yellow-orange (dust) while the ground between is yellow-green (sand), exactly what you expect with the larger coarser material settling in lower elevations.
The overview map provides the context, which might help explain the ridgeline.

The real reason the propaganda press is finally reporting Biden’s long-known mental decline
A free press is only a friend to the people if it is on
their side.
Many people on the right who follow politics have been somewhat astonished and amused at the aggressive and sudden willingness of the mainstream media — which I will from now on refer to as the propaganda press — to report in detail the long-known mental decline of President Joe Biden.
At first most thought, including myself, it was because of simple embarassment when their refusal to report these plain facts for the past four years was starkly revealed during Biden’s debate with Donald Trump on June 28th. For years they had worked hard to hide Biden’s declining mental health, going as far as accusing anyone on the right who reported it to be “spreading disinformation” (the modern catch-phrase for any reporting critical of Democrats) or to have created “deep fake” videos and manipulating footage to exaggerate Biden’s failings.
This past week I realized this conclusion is wrong. It is literally impossible for the members of this propaganda press to experience embarrassment. They weren’t embarrassed when it became clear their endless accusations that Trump had colluded with the Russians to win the election turned out to be a hoax, perpetrated entirely by the Hilary Clinton campaign. They weren’t embarrassed when it became clear that Hunter Biden’s laptop was real, that it wasn’t Russian disinformation as falsely claimed by 51 intelligence officers and then parroted by this propaganda press, and that everything on that laptop proved the depraved behavior of Hunter Biden and the criminal behavior of the entire Biden family, facts this propaganda press still refuses to cover.
Nor were they embarrassed by the numerous other false accusations against Trump that they have aggressively touted since 2017, all of which have been debunked time after time after time after time.
No, the reason the propaganda press is going full bore right now reporting Joe Biden’s mental decline is because these propagandists want a Democrat to win the eleciton in November, no matter what. » Read more
India picks astronauts to train for manned mission to ISS
India has now reduced from four to two the astronauts it is training for the fourth Axiom commercial mission to ISS, planned for launch no earlier than October 2024.
Only one of these two men will fly on that Axiom mission, with the other being the back-up should a change be required. The decision on who has not yet been made.
The astronauts will have to go to the United States ahead of the mission to train on the specifics of the ISS. “While they have general training for space-fairing, much of their training in India focussed on Gaganyaan modules. They will have to be familiarised with ISS modules and protocols,” the official said.
The names of the two astronauts has not been released, as far as I can find. Either way, this training will be used in preparation for India’s own manned Gaganyaan orbital mission, now scheduled for 2025, since three of these four men will fly on Gaganyaan.
Axiom signs $125 million deal with startup Gravitics to build a module for its space station
Artist conception of Gravitics’ Starmax
module, designed to fit inside Starship
The space station company Axiom on July 9, 2024 awarded a $125 million contract to the Seattle-based startup Gravitics to build a module for its upcoming space station.
The space station modules Gravitics is designing range from 3 meters (9 feet) to 8 meters (26 feet) in diameter. The largest module, which the company boasts will have the “largest interior volume in a standalone spacecraft,” is dubbed StarMax, a name inspired by SpaceX’s towering Starship rocket.
“We started by looking at Starship and saying, ‘Someone is going to maximize that payload volume,'” Doughan said.
It appears this contract is for one of the company’s smaller modules, though this could change with time.
Up until now, Axiom has hired the European company Thales Alenia to build the modules for its Axiom space station, with the first modules to initially be docked with ISS and then undocked to fly independent when ready. This contract, which is not exclusive, indicates Axiom’s desire to develop resources in America.
Launch failure for Chinese pseudo-company Ispace
Based on a very terse report in China’s state-run press today, there was a launch failure today for one of China’s pseudo-companies, launched from the Jiuquan spaceport in the northwest of China.
Further research suggests the failure was on Ispace’s Hyperbola-1 solid-fueled rocket. If so, this would be that rocket’s fourth failure out of seven launches.
No other information about the failure has so far been released.
India now has its own private company building space station modules
Even as India’s space agency ISRO gears up to build its own government space station, a Indian startup is proposing to build and launch its own commercial space station inflatable module, capable of carrying “6 to 16 personnel.”
The company, AkashaLabdhi, says it is negotiations with SpaceX for a launch target in 2027.
Founded in 2023, AkashaLabdhi has prepared its prototype model of the habitat called ‘Antariksh HAB’, according to a report by The Times of India. Antariksh HAB contains features such as an expandable shell that ensures ‘exceptional orbital debris and radiation protection’, the company says on its website. According to AkashaLabdhi, the design has multiple purposes besides space habitation. It can be used for microgravity experiments, satellite maintenance, orbital logistics storage. The company also hopes to see its usage for space tourism, armed forces operations among others.
“With a forward-looking perspective, this adaptable habitat holds potential for long-term lunar surface exploration,” the company said on its website. Built with several layers, the structure is meant to reach its intended orbit of 1,100 km. AkashaLabhi CEO Siddarth Jena told TOI on Wednesday that the structure will take about seven days to fully inflate, once it reaches its desired destination.
How real the plans of this company is unknown. That it exists at all and is proposing such ambitious plans illustrates however the capitalism in space revolution that is going on in India. The country has the technical capabilities to do such things, and is now free to go ahead due to the policies of the Modi government that has forced ISRO to provide aid and support, rather than control everything.
