Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 4, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The science team labels this a “concentric fill crater,” a term used by planetary scientists for Martian craters that appear to be filled with glacial material. That certainly appears to be the case, but this 3.5-mile-wide unnamed crater also appears to have been warped by the ice that impregnates the ground all around it.

The overview map above explains why. The white dot marks the location, on the eastern end of the 2,000-mile-long northern mid-latitude strip that I label glacier country, because almost every image in this region shows similar glacial features. Though it is hard to tell from the inset, all the craters here have similar glacial material within them, and the ground surrounding them also appears glacial in nature.

This particular location is at 40 degrees north latitude. While it might be difficult to establish a colony here, on ground that appears so unstable, going 700 to 800 miles to the southeast would put you in what is considered one of Mars’ prime mining regions. Thus, with the right equipment mining operations would have accessible water not that far away.

Google admits to bowing to Biden censorship, and vows to end all bans

10:37 am

Google admits to censorship
Click for original.

In a major announcement, the House Judiciary committee today revealed that Google has admitted that it had bowed to direct pressure by the Biden administration to censor conservatives, and it now vows to never bow to such pressure again.

The company has also agreed to allow everyone it banned due to that pressure to return to Youtube.

The graphic to the right comes from the committee’s announcement. All five points listed are critical to the future. First, Google now confirms the truth of another “rightwing conspiracy theory”. The Democratic Party under Biden was aggressively abusing its power to censor its opposition. Second, Google now admits it participated in this wrong-doing, and pledges to never do it again.

Finally, and most important, it notes the threat to freedom and free speech now posed by Europe and its new censorship laws. That threat is real, and unless American companies have the courage to tell Europe to pound sand, we could see them agreeing to squelch our speech in order to keep their businesses open in Europe. Google is essentially asking Congress and the federal government to do something to protect it from those laws.

NASA’s new class of astronauts illustrates its increasing shift to capitalism

10:19 am

NASA being conquered by Americans
NASA is being conquered by Americans

That two different former SpaceX employees, one of whom had already flown on a private mission in space, applied and were accepted by NASA yesterday — as part of the 24th class of astronauts since its creation three-quarters of a century ago — reveals the major shift that is occurring across the entire space industry, and most especially within NASA.

This new class of ten included four men and six women, the first time women were the majority chosen. More significantly however were the two former SpaceX employees.

Yuri Kubo, 40, is a native of Columbus, Indiana. He earned a bachelor’s degree in electrical engineering and a master’s in electrical and computer engineering from Purdue University. He spent 12 years working across various teams at SpaceX, including as launch director for Falcon 9 rocket launches, director of avionics for the Starshield program, and director of Ground Segment.

Anna Menon, 39, is from Houston and earned her bachelor’s degree from Texas Christian University with a double major in mathematics and Spanish. She also holds a master’s in biomedical engineering from Duke University. Menon previously worked in the Mission Control Center at NASA Johnson, supporting medical hardware and software aboard the International Space Station. In 2024, Menon flew to space as a mission specialist and medical officer aboard SpaceX’s Polaris Dawn. The mission saw a new female altitude record, the first commercial spacewalk, and the completion of approximately 40 research experiments. At the time of her selection, Menon was a senior engineer at SpaceX.

Menon is also married to another NASA astronaut, Anil Menon, making them the fourth married couple picked by NASA.

At first I wondered why either would want to leave the private sector to work at NASA, especially considering that the opportunity to fly in space through NASA is going to decline significantly in future years. Its Artemis program will at best launch once a year, carrying four, and when ISS retires NASA’s flights to the commercial stations will be fewer and farther apart.

Then I realized the financial and personal benefits of getting picked and trained by NASA as an astronaut. It is a wonderful item to put on one’s resume. These astronauts don’t have to stay at NASA forever. As the private commercial stations and other private manned capsules begin flying, those companies are going to need trained individuals to fly their ships and run their stations. Most will look for candidates from NASA’s astronaut corps.

The presence of those two SpaceX employees in this class also shows us the shift from the government to private enterprise. In the past almost all of NASA’s astronaut picks would have come from the military and academia (In fact, the other eight astronauts picked this time all have such backgrounds). Rarely would NASA have chosen anyone from the private sector.

The choice of two such private sector individuals by NASA yesterday is simply another indication of the agency’s shift from the top-down government model to the capitalism model. It is finally recognizing the private sector is (and has always been) the heart of America’s space effort, and it is beginning to reward it appropriately.

Even as that private sector begins to take over NASA itself.

Australian satellite startup to fly an instrument on private mission to Apophis

8:59 am

In March 2024 the orbital tug startup Exlab’s announced that it will use its orbital tug to deliver three cubesats to the asteroid Apophis when that object makes its next close fly-by of the Earth on April 13, 2029.

The California-based Exlab has now signed its first customer for that mission. An Australian satellite startup, Fleet Space Technologies, has agreed to fly an instrument on this private commercial mission.

Under the ApophisExL mission, Fleet will provide geophysical sensing technologies for ExLabs’ mothership to collect targeted data and characterize the asteroid. The datasets should enable new avenues for data sharing and commercial use, set criteria for prioritizing asteroids for prospecting and feed critical intelligence into planetary‑defence planning.

Fleet already has a contract to fly another instrument, a seismometer, on Firefly’s second Blue Ghost lander mission to the Moon. It has also developed and flown satellite instruments used to detect minerals on Earth.

Both companies are clearly aiming to enhance their brand name with this mission, set to launch in 2028.

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.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Universities in Taiwan and the United Kingdom sign partnership deal

8:42 am

The University of Surrey in the United Kingdom, a decades-long pioneer in cubesat technology, has now signed a partnership deal with the National Central University in Taiwan to work together.

Both universities began their work with cubesats to simply as a low-cost way to teach students about satellite design, but quickly found there was money to be made selling this technology commercially. This deal attempts to make two plus two equal six.

The collaborative plans follow multiple successful engagements between the Universities, from NCU professor Loren Chang joining a Taiwanese delegation to Guildford in March to partnership working between students from each university earlier this summer when Surrey and NCU worked with launch provider Stellar Kinetics at Etlaq Spaceport in Oman. The students worked together to integrate the Jovian-O and SIGHT space payloads that they had developed onto the KEA-1 rocket.

The universities also share research interests. The Surrey Space Centre has built space-based radiation detectors and, as part of the UK’s SWIMMR programme to improve resilience to space weather, developed miniature detectors to measure radiation at different altitudes and created a model for the UK Met Office to predict radiation levels experienced by aircraft.

NCU has developed multiple scientific payloads and small satellite science missions, including the Deep Space Radiation Probe (DSRP), which flew aboard the commercial lunar payload service provider, ispace, Inc.’s Resilience lunar lander, launched in January 2025. DSRP was operational for more than 97% of the five-month mission, providing measurements of the radiation belts, several solar radiation storms and radiation in lunar orbit. It was the first Taiwanese payload to fly and operate beyond Low Earth Orbit.

This deal now enhances both universities and the products both sell (educating students and developing new satellite technologies).

The left’s hatred and violence is finally driving people away

12:51 pm

Erika Kirk, at the moment she publicly forgave her husband's murderer
Erika Kirk, at the moment she publicly forgave
her husband’s murderer. Click for video.

As numerous pundits on the web have already noted, the assassination of Charlie Kirk last week has clarified most starkly the political divide in both the United States as well as across the world.

On the right, we have Kirk’s widow yesterday speaking at a memorial service for her husband, and with tears standing before the world to forgive his killer.

I forgive him. I forgive him because it was what Christ did, and it is what Charlie would do. The answer to hate is not hate. The answer, we know from the Gospel, is love. And always love. Love for our enemies, and love for those who persecute us.

Her speech matched the general tone of most of the speakers at that memorial service. The service itself, as well as the numerous peaceful candlelight vigils nationwide in memory of Kirk, illustrate clearly the response of the right to this heinous act. No riots, no violence, no calls for bloodshed. Only prayer and a cold fury to make sure such violence never happens again.

That tone was set by Kirk himself, before he died. All he ever did was want to debate his very mainstream conservative ideas with leftists, with good will and rationality. He proved it in a text he sent to leftist pundit Van Jones just before his murder:

I’d love to have you on my show to have a respectful conversation about crime and race. I would be a gentleman as I know you would be as well. We can disagree about the issues agreeably.

The left’s response to Kirk however has been not love or good will but hate. Hundreds and hundreds of partisan leftists went on social media to gleefully celebrate his assassination. Leftist politicians and entertainers defamed both him and what he stood for, with lies and slanders. And when the television show of one entertainer, Jimmy Kimmel, got canceled by ABC because Kimmel had falsely claimed on the air that a Trump supporter had killed Kirk, one leftist and former teacher’s union employee decided it was okay to protest Kimmel’s cancellation by firing multiple bullets into the offices of an ABC affiliate in Sacramento. The man, Al Hernandez Santana, also has an extensive X feed where he had expressed hate for Donald Trump, often wishing him dead.

He is clearly not sane, but he is also not an outlier on the left. The response of the left to Kirk’s murder has revealed that for too many Democratic Party supporters, Santana is mainstream.

A galaxy sunnyside up

A galaxy sunnyside up
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, is the Hubble picture of the week. It shows a strange galaxy that defies categorization. From the caption:

The galaxy in question is NGC 2775, which lies 67 million light-years away in the constellation Cancer (The Crab). NGC 2775 sports a smooth, featureless centre that is devoid of gas, resembling an elliptical galaxy. It also has a dusty ring with patchy star clusters, like a spiral galaxy. Which is it, then: spiral or elliptical — or neither?

Because we can only view NGC [2775 from one angle, it’s difficult to say for sure. Some researchers have classified NGC 2775 as a spiral galaxy because of its feathery ring of stars and dust, while others have classified it as a lenticular galaxy. Lenticular galaxies have features common to both spiral and elliptical galaxies. It’s not yet known exactly how lenticular galaxies come to be, and they might form in a variety of ways.

To me, the galaxy most resembles a fried egg, sunnyside up, though I very strongly doubt that was the process that formed it. The bright center however suggests that something there has in the past emitted a lot of energy and radiation, thus clearing out the gas and dust from that center.

The swamp comes up with a swamp solution for promoting space

9:01 am

Like pigs at the trough
Like pigs at the trough

A group of senators last week announced the re-introduction of a bill they had proposed previously in 2023 that they claim would encourage new spaceport development across the United States. From their press release:

Today, U.S. Senators John Hickenlooper, John Cornyn, Ben Ray Luján, and Roger Wicker introduced the bipartisan Spaceport Project Opportunities for Resilient Transportation (SPACEPORT) Act, which would encourage the development of commercial spaceports through the modernization of the Federal Aviation Administration’s (FAA) Space Transportation Infrastructure Matching (STIM) grant program.

Spaceports, including the Colorado Air and Space Port in Adams County, are ground-based launch and reentry sites that can be used to support public and private ventures into space. “Spaceports are Colorado’s gateway to the commercial space boom, and we need to prioritize that infrastructure if we want to stay at the top of the space industry,” said Hickenlooper. “American space exploration has come a long way, but we can and should go even further,” said Cornyn. “By investing in our spaceport infrastructure, this legislation helps ensure the U.S. space industry remains competitive and is prepared to handle future national security threats.”

Though two of these four senators are Republicans (Cornyn and Wicker), the political leanings of this group is decidedly uni-party and establishment based. Polls for example show that Cornyn is not liked by conservatives in Texas, and will lose a primary challenge from the state’s attorney general Ken Paxton. Wicker doesn’t have the same polling issues, but he has also taken positions that suggests he is a willing member of the Republican establishment that has resisted change for decades.

And the actual bill [pdf] itself proves that all four senators are pure swamp. It doesn’t do anything to directly support spaceport development, as Hickenlooper and Cornyn claim. Instead, it would create a $10 million grant fund that the transportation secretary could hand out willy-nilly each year to political friends and buddies. It would also require the heads of Transportation, Defense, Commerce, and NASA to issue a report every four years that simply reviews the state of America’s space industry and describes it.

The bill does nothing to reduce regulation, the main obstacle blocking the U.S. rocket and space industry. If anything, it allows that red tape to flourish by creating this slush fund that politicians can later use to bribe private companies. The report itself will require more bureaucrats and paperwork, and will act to prevent that bureaucracy from doing its regulatory responsibilities, thus slowing license approvals further.

Introducing a bill like this does not guarantee passage of course. It failed previously in 2023. I suspect it is even more likely to fail now, because the trend appears to be moving away from this kind of funding and legal gabblygook.

Failed launch by Iran

11:49 pm

Though information is at present scarce and contradictory, Iran in the past few days appears to have made one or two launch attempts, either of a missile system near Tehran or of its orbital Zoljanah rocket from its Semnan spaceport to the east.

According to this Newsweek report, the launch was of a “suspected missile system … near its capital, Tehran.”

According to this tweet from astronomer Jonathan McDowell, who monitors such activity, it was a “possible failed orbital launch attempt … of an IRGC Zoljanah launch vehicle from Semnan, Iran.”

There is also this tweet from Iran media, which calls it a “missile” and a “test” that failed.

I think these conflicting reports are describing the same launch. If its the latter, then the question is whether it was a Zoljanah rocket, and if so was it attempting its first orbital launch after two suborbital tests in ’21 and ’22?

South Korean rocket startup Innospace wins launch and marketing contract with German broadcast company

9:31 am

The South Korean rocket startup Innospace announced last week that it has signed a $5.8 million launch with the German broadcast company Media Broadcast Satellites (MBS) to not only launch two MBS satellites in 2026 and 2028 using its Hanbit rocket, but to have MBS market the rocket in Germany.

Under the agreement, INNOSPACE will carry out two HANBIT launch missions to deploy MBS satellites into Low Earth orbit (LEO), with one launch in 2026 and the other planned by 2028. In both launch missions, MBS satellites will serve as the primary payloads, with priority in launch scheduling and orbit determination.

INNOSPACE also signed a separate contract on the same day, officially appointing MBS as its exclusive agent for launch service sales and marketing within Germany, marking the company’s entry into the European space launch market. Following the contract, MBS will exclusively distribute launch services based on the HANBIT series to satellite customers in Germany.

Innospace has not yet launched Hanbit. It had hoped to attempt the first launch in July, but in May it delayed it to the end of 2025 due to issues found in a first stage pump. The launch itself will take place at Brazil’s long abandoned Alcântara spaceport on that nation’s northeast coast.

Avio wins U.S. launch contract for its Vega-C rocket

9:19 am

Capitalism in space: In what I think is a first, the Italian rocket company Avio has won a Vega-C launch contract without any participation from the European Space Agency’s (ESA) commercial division Arianespace.

The contract is also with an American company, SpaceLaunch, to put an “institutional Earth observation satellite” in orbit in 2027.

The significance of the deal is that Avio is now successfully marketing and selling its Vega-C rocket, without the middleman Arianespace taking a cut. As part of the shift of ESA and Europe to the capitalism model, whereby it no longer runs things but acts merely as a customer, it also freed Avio from the clutches of Arianespace. Previously, Avio built the rocket for that government agency, which then marketed and sold it to satellite companies. Avio had no control over profit or price. In fact, it didn’t really own its own rocket.

This absurd situation is now ending. There are still a handful of Vega-C launches that were contracted for under Arianespace, but after these Avio will be completely in charge. This deal, announced yesterday, is the beginning of that process.

Blue Origin wins contract to bring NASA’s Viper rover to the Moon

9:12 am

NASA yesterday awarded Blue Origin a contract to use its Blue Moon lunar lander to transport the agency’s troubled Viper rover to the Moon’s south pole region.

The CLPS task order has a total potential value of $190 million. This is the second CLPS lunar delivery awarded to Blue Origin. Their first delivery – using their Blue Moon Mark 1 (MK1) robotic lander – is targeted for launch later this year to deliver NASA’s Stereo Cameras for Lunar-Plume Surface Studies and Laser Retroreflective Array payloads to the Moon’s South Pole region.

With this new award, Blue Origin will deliver VIPER to the lunar surface in late 2027, using a second Blue Moon MK1 lander, which is in production. NASA previously canceled the VIPER project and has since explored alternative approaches to achieve the agency’s goals of mapping potential off-planet resources, like water.

The contract does not guarantee this mission. NASA has several options along the way to shut things down, depending on the milestones Blue Origin achieves. The first of course is the success of that first lunar lander.

The announcement does not make clear how NASA is going to pay for the work needed to finish Viper. VIPER was originally budgeted at $250 million. When cancelled in 2024 its budget had ballooned to over $600 million, and that wasn’t enough to complete the rover for launch. Moreover, after getting eleven proposals from the private sector companies to finish and launch Viper, in May 2025 NASA canceled that solicitation.

It is very likely Blue Origin is picking up the tab, but if so the press release does not say so.

FAA releases proposed revisions to environmental assessment at Boca Chica to accomodate full orbital testing and return of both Superheavy and Starship

12:33 pm

The planned return trajectories for both Superheavy and Starship
The planned return trajectories for both
Superheavy and Starship

The FAA today released [pdf] a new draft of the environmental assessment of SpaceX’s Superheavy/Starship operations at Boca Chica that will allow for full orbital flights as well as for both to return to that launchpad.

The two maps to the right show the two planned return paths for Superheavy (top) and Starship (bottom) as it comes back from orbit. In both cases the ships will return to Boca Chica to be caught by tower chopsticks. The reassessment analyzed the impacts of these trajectories, including its impact on aviation traffic, and concluded the proposal was acceptable. From its conclusion:

The 2022 PEA [Programmatic Environmental Assessment] and April 2025 Tiered EA [environmental assessment] examined the potential for significant environmental impacts from Starship-Super Heavy launch operations at the Boca Chica Launch Site and defined the regulatory setting for impacts associated with Starship-Super Heavy. The areas evaluated for environmental impacts in this Tiered EA include aviation emissions and air quality; noise and noise-compatible land use; hazardous materials; and socioeconomics. In each of these areas, the FAA has concluded that no significant impacts would occur as a result of the Proposed Action. [emphasis mine]

This approval is still only a draft. It must go through a public comment period, ending October 20, 2025. There will also be a virtual public meeting on October 7, 2025. Information about submitting comments or participating in that virtual meeting can be found here.

Such meetings are likely to see the leftist anti-Musk crowd come out in droves, screeching how we are all gonna die if these launches are allowed. The FAA will nod its head, and then ignore the Chicken Littles and approve this plan.

The plan itself tells us that SpaceX is definitely gearing up the first orbital flights of Starship next year, along with the first attempts to catch it with the tower chopsticks.

Inexplicable very large patterns found in Saturn’s upper atmosphere

9:40 am

Beads and arms in Saturn's upper atmosphere
Click for original image.

Using the Webb Space Telescope’s infrared capabilities, scientists have detected several different and inexplicable large atmospheric structures linked somehow to the gas giant’s north pole aurora.

The two images to the right, cropped, reduced, and annotated to post here, show both types of newly discovered features.

The international team of researchers, comprising 23 scientists from institutions across the UK, US and France, made the discoveries during a continuous 10-hour observation period on 29 November 2024, as Saturn rotated beneath JWST’s view. The team focused on detecting infrared emissions by a positively charged molecular form of hydrogen, H3+, which plays a key role in reactions in Saturn’s atmosphere and so can provide valuable insights into the chemical and physical processes at work. JWST’s Near Infrared Spectrograph allowed the team to simultaneously observe H₃⁺ ions from the ionosphere, 1,100 kilometres above Saturn’s nominal surface, and methane molecules in the underlying stratosphere, at an altitude of 600 kilometres.

In the electrically-charged plasma of the ionosphere, the team observed a series of dark, bead-like features embedded in bright auroral halos. [top picture] These structures remained stable over hours but appeared to drift slowly over longer periods.

Around 500 kilometres lower, in Saturn’s stratosphere, the team discovered an asymmetric star-shaped feature [bottom picture]. This unusual structure extended out from Saturn’s north pole towards the equator. Only four of the star’s six arms were visible, with two mysteriously missing, creating a lopsided pattern.

A more accurate word for the “beads” I think would be “patches”, as they are not small but major dark regions that appear to rotate with the planet, as do the arms. Both also seem to be related to each other as their rotations match, though one sits about 300 miles lower in the atmosphere. As noted in the press release, “the processes that are driving the patterns may influence a column stretching right through Saturn’s atmosphere.”

All guesses. All we have at this point is a truly intriguing observation.

Luxembourg cargo capsule startup Space Cargo raises $32 million in private investment capital

9:14 am

The Luxembourg cargo capsule startup Space Cargo has now raised $32 million in private investment capital in a new funding round focused on developing its BentoBox platform for in-space manufacturing and experimentation.

On 15 September, the company announced that it had closed a €27.5 million Series A funding round led by Expansion Ventures and supported by Eurazeo. The round included participation from the European Innovation Council, the European Investment Bank, and the Luxembourg Future Fund II, which is managed by Société Nationale de Crédit et d’Investissement and the European Investment Fund. It also included contributions from numerous private investors who participated through the crowd-equity platform Tudigo.

Unlike Varda’s returnable capsule, BentoBox is smaller and not designed to return to Earth. Instead it gets launched incorporated on orbital spacecraft built by others, such as Thales Alenia’s REV-1 tug and Atmos’s Phoenix returnable capsule.

Astra is now targeting mid-’26 for first launch of its new Rocket-4 rocket

9:00 am

According to a presentation by Astra officials this week, the company now plans the first launch of its larger Rocket-4 rocket in the summer of 2026, followed by a second launch in the fall for the Pentagon.

The summer 2026 inaugural launch will be a test flight, Kemp said, followed by one in October or November for the Defense Department’s Space Test Program. Astra plans quarterly launches of Rocket 4 in 2027, with long-term goals for much higher launch rates. Astra has maintained plans to make Rocket 4 a transportable launch system using standard shipping containers, allowing it to operate from sites with little more than a concrete pad.

This company has had a checkered history. It built and launched its smaller Rocket-3 rocket several times back in 2021 and 2022, with mixed results. After those launch failures it then decided to retire that smaller rocket for Rocket-4, only to run out of cash in 2023-2024. In 2024 its founders put together the cash to buy up the company’s stock to go private, and since then it has made most of its money from that one military test contract as well as selling its electrical propulsion systems to satellite companies.

If it gets Rocket-4 off the ground and begins regularly launches it will be an amazing recovery.

Japan closes down its Akatsuki Venus orbiter mission

8:50 am

japan’s space agency JAXA today announced that it has shut down down operations on its Akatsuki orbiter, in orbit around Venus since 2015.

Communication with “Akatsuki” was lost during operations near the end of April 2024, triggered by an incident in a control mode of lower-precision attitude maintenance for a prolonged period. Although recovery operations were conducted to restore communication, there has been no luck so far. Considering the fact that the spacecraft has aged, well exceeding its designed lifetime, and was already in the late-stage operation phase, it has been decided to terminate operations.

Akatsuki has a interesting history. Launched in 2010, it failed to enter Venus orbit as planned in two attempts in 2010 and 2011 because of a failure in its main engine. Engineers then improvised and — after orbiting the Sun for several years — were able to get it into Venus orbit in 2015 using only its attitude thrusters. Its primary mission ended in 2018, but it continued to study Venus’ atmosphere since.

Russia’s Bion-2 capsule returns to Earth after a month in space

8:44 am

After a month in space carrying a cargo of biological samples, including 1,500 fruit flies and 75 mice, Russia’s Bion-2 capsule was successfully recovered today after landing in southern Russia.

Following the landing, some mice was [sic] to be dissected at the site, followed by further dissections on the 1st, 5th, 15th and 30th days after landing to study the effects of space conditions on live organisms.

While resembling the commercial private returnable capsules, such as Varda’s, that are being developed, the difference is significant. Russia has been flying these capsules for decades, which is actually an upgrade from the very first Vostok capsule which it flew Yuri Gagarin in 1961. However, the research has always been focused not on producing a product for sale on Earth but related to Russia’s manned program. Thus, the results has always been somewhat dead end. Expect the same here.

At last some real pushback against the left’s slander culture

12:04 pm

For years I have been writing about the slander culture of the left, whereby they can say any lie about anyone who disagrees with them without any consequence. These lies are often pure slander and defamation, based on no facts. Often they grow to a point that anyone attacked in this manner becomes a persona non grata, ostracized by all society out of fear.

Here are some recent examples of this kind of slander:

This is what destroyed the Proud Boys organization. The left — and the propaganda press that works for it — labeled it as “racist”, “white supremacist”, and “neo-fascist” based on no evidence, so that soon it collapsed because ordinary people were afraid to associate with it. And in describing this slander campaign back in 2019, I correctly predicted even worse:

I fully expect the rhetoric against Trump supporters in the coming election to spread and get more vicious. This in turn will act to encourage more extreme actions, including violence comparable to what Antifa now does with impunity in Portland. Be prepared. When people abandon the truth for emotional labels inspired by hate, they are liable to do anything.

Meanwhile, this lying name-calling never seemed to carry any consequences. Big name Democratic Party politicians, celebrities, and leftist pundits could defame conservatives routinely in the same manner and get away with it. The only ones who would suffer would be the unjustly accused.

The events in the past two days in connection with former host Jimmy Kimmel of Jimmy Kimmel Live! however tells me that the murder of Charlie Kirk has truly changed things.

Astronomers refine the spin and size of Hayabusa-2’s next target asteroid

10:15 am

Using a number of ground-based telescopes, astronomers have determined that asteroid 1998 KY26, which Japan’s Hayabusa-2 probe will visit in 2031, spins much faster and is much smaller than previously estimated.

The new observations, combined with previous radar data, have revealed that the asteroid, 1998 KY26, is just 11 meters wide. It is also spinning about twice as fast as previously thought: “One day on this asteroid lasts only five minutes!” he says. Previous data indicated that the asteroid was around 30 meters in diameter and completed a rotation in approximately 10 minutes. The smaller size and faster rotation will make the spacecraft’s touchdown maneuver more difficult to perform than anticipated.

The observations also found that 1998 KY26 is bright, suggesting it is a solid object, not a rubble pile. Its fast rotation adds weight to this conclusion.
