Mireille Mathieu – La Marseillaise

6:01 pm

An evening pause: Performed live in 1989, to celebrate the 100th anniversary of the Eiffel Tower. What I especially like are the English subtitles, because for some reason this song is rarely translated. Knowing the meaning of what they are singing in the scene in the movie Casablanca makes that scene even more moving.

Hat tip Tom Biggar.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

China launches two GPS-type satellites

4:06 pm

China today successfully launched two more BeiDou satellites for its GPS-type navigation constellation, its Long March 3B rocket lifting off from its Xichang spaceport in the southwest of China.

No word on where the strap-on boosters and lower stages crashed in China, all using toxic hypergolic fuels.

The leaders in the 2024 launch race:

92 SpaceX
39 China
11 Russia
10 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 107 to 61, while SpaceX by itself still leads the entire world, including American companies, 92 to 76.

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.

The Democrats: 28% think it would be a good thing if Trump were killed

2:05 pm

Poll proving how murderous the Democrats have become
Click for original image.

The Democrats and their supporters might claim they stand for democracy and freedom and fair elections, but their own words prove this endlessly to be a lie. In a new poll of a 1,000 registered voters, 28% of the Democrats thought the country would be better off if Trump were assassinated.

Sadly, as shown by the graph to the right, 7% of the Republicans polled also thought killing Trump would a good thing.

The difference between the two numbers however illustrates the stark difference between the two parties, and helps explain why there have been two assassination attempts on Trump and none on the Democratic Party candidates. Republicans mostly support democracy and free and fair elections. A large percentage of Democrats no longer do.

Furthermore, Democrats also appear to be so filled with their hatred of Trump and any opposition that they can no longer think rationally about anything. The poll also found that 70% believed it likely or somewhat likely that the second assassination attempt was faked by Trump and his campaign.

All of this hatred among grassroots Democrats is worsened because the leadership of the Democratic Party keeps feeding it. » Read more

Webb takes an infrared look at a galaxy looked at by Hubble

12:21 pm

Comparing Hubble with Webb
For original images go here and here.

Cool image time! The bottom picture on the right, cropped to post here, is a just released false color infrared image of the galaxy Arp 107, taken by the Webb Space Telescope. The picture at the top is a previously released optical image taken by the Hubble Space Telescope and featured as a cool image back in September 2023. The Hubble image was taken as part of a survey project to photograph the entire Arp catalog of 338 “peculiar galaxies,” put together by astronomer Halton Arp in 1966. In this case Arp 107 is peculiar because it is actually two galaxies in the process of merging. It is also peculiar because the galaxy on the left has an active galactic nuclei (AGN), where a supermassive black hole is sucking up material and thus emitting a lot of energy.

The Webb infrared image was taken to supplement that optical image. The blue spiral arms indicate dust and star-forming regions. The bright orange object in the center of the galaxy is that AGN, clearly defined by Webb’s infrared camera.

When I posted the Hubble image in 2023, I noted that “if you ignore the blue whorls of the left galaxy, the two bright cores of these merging galaxies are about the same size.” In the Webb image the two cores still appear about the same size, but in the infrared they produce emissions in decidedly different wavelengths, as shown by the different false colors of orange and blue. The core of the galaxy on the right is dust filled and forming stars, while the core of the left galaxy appears to have less dust with all of its emissions resulting from the energy produced by the material being pulled into the supermassive black hole.

The universe is very active and changing, but to understand that process we humans have to look at everything across the entire electromagnetic spectrum, not just in the optical wavelengths our eyes see.

Newly discovered potentially dangerous asteroid found to be a contact binary

Radar images of asteroid 2024ON
Click for original image.

Radar images taken during the close fly of a newly discovered potentially dangerous asteroid has revealed that it is a contact binary, formed by two objects stuck together to produce a single asteroid with a peanutlike shape.

Discovered by the NASA-funded Asteroid Terrestrial-impact Last Alert System (ATLAS) on Mauna Loa in Hawaii on July 27, the near-Earth asteroid’s shape resembles that of a peanut. Like the asteroid 2024 JV33 that made close approach with Earth a month earlier, 2024 ON is likely a contact binary, with two rounded lobes separated by a pronounced neck, one lobe about 50% larger than the other. The radar images determined that it is about 755 feet (350 meters) long. Features larger than 12.3 feet (3.75 meters) across can be seen on the surface. Bright radar spots on the asteroid’s surface likely indicate large boulders. The images show about 90% of one rotation over the course of about six hours.

The radar images were taken one day before that close approach of 620,000 miles on September 17, 2024, and once again show that a large number of near-Earth asteroids, as much as 14%, are contact binaries. The data also helped better refine 2024ON’s orbit around the Sun, which show that though the asteroid has the potential to hit the Earth, its path will not do so for the foreseeable future.

Phobos rising and Earth setting as captured together by Curiosity

10:56 am

Phobos and Earth in the Martian sky
Click for original image.

Cool image time! The picture to the right, enhanced and reduced to post here, was taken by the high resolution camera on the Mars rover Curiosity on September 5, 2024.

What makes this picture unique are the two tiny spots near the upper right. For the first time, Curiosity’s camera was able to capture both the Earth and the Martian moon Phobos in the same picture, when they were also very close to each other in the sky. From the caption:

NASA’s Curiosity Mars rover used its Mast Camera, or Mastcam, to capture this view of Earth setting while Phobos, one of Mars’ two moons, is rising. It’s the first time an image of the two celestial bodies have been captured together from the surface of Mars.

The image is a composite of five short exposures and 12 long exposures all taken on Sept. 5, 2024, the 4,295th Martian day, or sol, of Curiosity’s mission. An inset in the image [found here] shows Phobos on the left and Earth on the right. From the rover’s perspective, the inset area would be about half the width of a thumb held at arm’s length.

The dark shape in the lower left is one of the buttes that surround Curiosity as it has been climbing up Mount Sharp and traversing inside the Gediz Vallis slot canyon.

The inset provides a close-up of the two objects, but the resolution is poor. To me, it is much more interesting to look at the picture to the right, that shows what these two objects actually looked like in the sky of Mars.

FCC commissioner slams FCC for its partisan hostility to SpaceX

The FCC proves its partisan hostility to SpaceX
The FCC proves its partisan hostility to SpaceX

Even as the FAA has increasingly appeared to be harassing SpaceX with red tape, FCC commissioner Brendan Carr this week slammed his own agency for what appears to be clearly partisan hostility to SpaceX in its recent decisions and public statements.

Carr noted how only last year the FCC had canceled an almost $900 million grant that it had previously awarded to SpaceX for providing rural communities internet access. When it did so, the FCC claimed that the company had failed to “demonstrate that it could deliver the promised service.”

That claim of course was absurd on its face, considering that Starlink was the only available commercial system that was actually doing this, directly to individual rural customers.

Carr noted however that this absurd FCC decision was made even more ridiculous this week by the FCC’s chairperson, Jessica Rosenworcel, who accused SpaceX of being a “monopoly” because of its success in launching Starlink satellites and providing this service ahead of everyone else.

Sierra Space successfully tests equipment for extracting oxygen from the lunar soil

9:57 am

In a press release this week Sierra Space revealed that it has successfully tested an extraction system that can gather up the abrasive lunar regolith and then heat it to high temperatures in order to extract and use the oxygen contained in that soil.

Temperatures in which the Sierra Space Carbothermal Oxygen Production Reactor were tested ranged from minus 45 degrees Celsius to 1,800 degrees Celsius. In addition to the challenges of functioning from sub-zero to hotter-than-lava temperatures, the hardware was required to move the simulated lunar regolith – a very abrasive and jagged material because it does not have the weathering processes found on Earth – through its system. The potentially damaging particles were handled effectively by the hardware and gasses were successfully sealed inside the reactor, thanks to Sierra Space’s use of a patent-pending valve design that previously demonstrated functionality to greater than 10,000 cycles.

The tests confirmed that Sierra Space’s system can successfully handle regolith that would be delivered from a lunar rover or robotic arm and automatically bring it into the reaction chamber, perform the carbothermal reduction reaction process to extract the oxygen from the minerals in the regolith, and remove the processed regolith from the system so the operation can be repeated.

This research is similar to the extraction system the Chinese are developing, though it appears Sierra’s system appears considerably closer to a finished product, as it is already being tested.

Eutelsat awards multi-launch contract with Mitsubishi

9:42 am

The French communications satellite company Eutelsat has awarded the Japanese company Mitsubishi a multi-contract using its H3 rocket.

The company did not reveal the contract amount or the number of launches involved. The first launches however will begin in 2027, with company officials explaining why they signed the deal.

The operator already has launches mostly covered for deploying its next-generation OneWeb broadband satellites in low Earth orbit (LEO), CEO Eva Berneke recently told SpaceNews. However, these launches include 3D printing specialist Relativity Space’s Terran R vehicle and Europe’s next-generation launcher Ariane 6, which have both already experienced development delays.

Ariane 6 is also part of the multi-billion-dollar launch campaign Amazon plans to kick off this year for its LEO constellation. “Given that Amazon has acquired Ariane 6 rockets, if we wanted to use it in, say, 2027, are we going to fit into their launch manifest or not?” Berneke told SpaceNews in the interview.

There are two interesting aspects to this deal. First, Eutelsat decided it needed to diversify its launch providers. The status of Relativity’s Terran-R rocket remains uncertain, and if it goes under Eutelsat would be left with just Ariane-6, which has its own issues and might not be able to meet the demand.

Second, Eutelsat clearly decided it did not want to give this business to SpaceX. I guarantee SpaceX’s price was less than Mitsubishi’s since the H3 is entirely expendable and very expensive, developed by Mitsubishi primiarly for the Japanese government (which paid the bills) and not as a player in the international launch market. Eutelsat made this choice for probably good and bad reasons. The good reason: All satellite companies need to encourage the success of as many launch providers as possible, to increase its options and competion. Giving business to Mistubishi serves that purpose.

The bad reason? Among many in Europe and elsewhere there is a childish resentment of SpaceX, simply because. No one will say so publicly, and if asked everyone will deny it, but the evidence clearly suggests that this silly emotional factor exists.
