Pentagon is now all-in on capitalism in space

9:40 am

Capitalism in space: Based on recent remarks from officials as well as a number of newly issued contracts, the U.S. military has now decided to completely shift from designing and building its own space hardware — which it has increasingly done badly at great cost — to simply becoming a customer buying products from the private sector.

First we have remarks and press announcements from top Pentagon officials, stating this policy change.

Deputy Defense Secretary Kathleen Hicks, who has spearheaded Pentagon efforts to bring cutting-edge technology into defense programs, is overseeing the military’s first commercial space integration strategy.

The new strategy comes as the Pentagon seeks to tap into advancements in commercial space technology to maintain an advantage over China, now seen as America’s top military competitor. “At Deputy Secretary Hicks’ direction, the Department is currently developing our first DoD Commercial Space Integration Strategy in order to drive integration and ensure the availability of commercial space solutions during competition, crisis and conflict,” Pentagon Spokesman Eric Pahon said Nov. 27 in a statement to SpaceNews.

Nor are these merely words. On November 22, 2023 the military announced a request for proposals from twenty different commercial space companies to provide all of its military needs in orbit, with potential contracts worth up to $900 million.

The Proliferated Low Earth Orbit (PLEO) Satellite-Based Services contract, first announced in July, is run by the Defense Information Systems Agency (DISA) on behalf of the Space Force’s Commercial Satellite Communications Office (CSCO), a central marketplace for satellite services operated by the Space Systems Command.

…The PLEO contract “supports the Department of Defense’s requirement to provide worldwide, low-latency PLEO services,” said DISA. The IDIQ contracting method allows the Department of Defense, other federal agencies and international allies “to procure fully managed satellite-based services and capabilities for all domains (space, air, land, maritime and cyber) with a consistent, quality-backed, low-latency offering.”

This shift is excellent news, not only for the commercial space industry but for the American military itself. The former is guaranteed to grow and innovate as these companies compete for military business, while the latter will get what it needs more quickly and at much lower cost.

Starlink now operating for Israel in Israel and Gaza

9:26 am

As part of Elon Musk’s trip to Israel this week he negotiated a deal with the Israeli ministry of communications to activate Starlink over both Israel and Gaza, allowing its use by the military there.

The deal is in addition to Tesla’s recent announcement that Israelis can now charge their cars for free at its charging stations.

Musk’s trip also has put the lie to the slanders of the left that have accused him of being an anti-Semite simply because he correctly noted the leftist bias of the Anti-Defamation League (ADL), made worse by its effort to censor and blackball people. That slander has had no traction, because Elon Musk is very well known to the public, and it quickly recognized that it was an utter lie. Musk’s trip to Israel simply underlines the dishonesty of that accusation.

British scientists get their own Bennu sample to study

9:16 am

The British History Museum has now received a small sample of material from the asteroid Bennu, brought back to Earth by the planetary probe OSIRIS-REx.

The first two years of research at the Natural History Museum will focus on non-destructive tests, such as X-ray diffraction and electron microscopy to learn about Bennu’s mineral composition and structure. The largest grains in the sample are on the order of millimetres wide, while the smallest are mere dust particles. “It doesn’t sound like a lot of material, but it’s plenty to work with,” King said.

The museum is home to one of the world’s leading meteorite collections, and the staff are well-used to handling small amounts of extremely precious materials from outer space. Unlike meteorites that have been baked and battered on their fiery passage through Earth’s atmosphere, the dust and rocky fragments from Bennu were brought to Earth in pristine condition, allowing scientists a rare glimpse of the unaltered asteroid.

The last sentence says it all. Up until recently, researchers have had a distorted view of the overall make-up of asteroids because the oldest kinds, carbonaceous chondrite, are the most delicate and get significantly changed by their passage through the Earth’s atmosphere. The samples from Bennu and Ryugu are changing this, and will eventually revolutionize the understanding scientists have of our present solar system.

SpaceX launches 23 Starlink satellites

9:00 am

SpaceX last night successfully launched another 23 Starlink satellites into orbit, its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its seventeeth flight, landing on a drone ship in the Atlantic. That SpaceX now has several first stages that have been reused this much and it isn’t considered news is in itself a story. The company has actually gotten this rocket to perform like an airplane, a goal that Elon Musk aspired too more than a decade ago.

The leaders in the 2023 launch race:

87 SpaceX
53 China
15 Russia
7 Rocket Lab
7 India

American private enterprise now leads China 99 to 53 in successful launches, and the entire world combined 99 to 84. SpaceX meanwhile widens its lead over the rest of the world (excluding American companies) 87 to 84.

As a number of my readers have noted, the U.S. lead this year is entirely due to SpaceX, indicating a dominance that is actually unhealthy. Other American companies need to come forward and challenge it, because the competition will spark innovation and better rocketry. With no competition, it is inevitable that even SpaceX could get lazy.

  • Astra obtains $2.7 million in new financing

    • The status of this company is right now entirely unknown. It is not clear how this financing impacts the proposal of the company’s founders to buy up the stock and take Astra private. Nor is it clear how this financing satisfies other loans that have already expired and had to be paid. Based on the article, it seems to me that the company will soon have to shut down due to lack of cash.

Mars’ giant sinkholes

12:15 pm

The floor of one of Mars' giant sinkholes

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on June 27, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a small section of the floor and northern slope of Hebes Chasma, one of the many very large enclosed pits that can be found to the north of Valles Marineris, the largest canyon in the solar system. Though Hebes seems small next to the 1,500 mile long Valles Marineris, it still is 200 miles long by 80 miles wide, and could easily fit a half dozen Grand Canyons within it.

For example, the Grand Canyon is from 4,420 to 5,400 feet deep, hiking down from the south and north rim lodges respectively, which sit about ten miles apart. On this picture, the peak on the right sits about 5,300 feet above and only about 3.8 miles from the low spot on the bottom left, which means this one small picture encapsulates the Grand Canyon. And yet, the northern rim of Hebes sits another 21,000 feet higher and twelve miles away. And the entire chasma itself extends 50 miles to the west, 150 miles to the east, and 50 miles to the south.

Blue Origin begins third major expansion of Huntsville facility

9:03 am

Blue Origin has been issued a $8.4 million building permit by local Huntsville authorities as part of the third major expansion of its rocket-manufacturing facility there.

According to the report, of the 377 permits issued so far in October and November, this was the largest. All three expansions have occurred in the past three years.

The article however includes this ridiculous statement:

The aerospace company owned by Jeff Bezos, Blue Origin has emerged as one of the top commercial spaceflight companies as the country has placed a renewed effort on returning to the moon and eventually to Mars.

How could Blue Origin be “one of the top commercial spaceflight companies” when it has still not launched anything into orbit? Even the tiny rocket startup Astra, now on the verge of bankruptcy, put more mass into orbit than Blue Origin. Everyone has, since the mass Blue Origin has put into orbit so far equals a nice fat zero.

This expansion however does suggest that something positive might finally be happening at the company. With the removal of Bob Smith as CEO and Jeff Bezos now living in Florida and closer to the action it could be that the continuing string of non-accomplishment that has made Blue Origin a bit of a joke in the space industry might possibly be ending.

We shall have to wait and see, however.

Russia launches military satellite

7:59 pm

Russia today successfully placed a classifed military satellite in orbit, its Soyuz-2 rocket lifting off from its Plesetsk spaceport in northern Russia.

The satellite is likely a reconnaissance satellite. No word on where the rocket’s core stage and strap-on boosters landed inside Russia, though launches from Plesetsk generally head north over very empty regions and the Arctic, and as the satellite appears to have an orbit with an inclination of 67 degrees that is likely in this case.

The leaders in the 2023 launch race:

86 SpaceX
53 China
15 Russia
7 Rocket Lab
7 India

American private enterprise still leads China 98 to 53 in successful launches, and the entire world combined 98 to 84. SpaceX meanwhile maintains its lead over the rest of the world (excluding American companies) 86 to 84.

Did the Capitol police instigate violence by firing on peaceful January 6th demonstrators?

Video evidence recently released by House speaker Mike Johnson, combined with many videos taken by participants during the January 6, 2021 demonstrations on Capitol Hill, now suggest strongly that the violence was instigated by the DC police, not the January 6th demonstrators, who until then had been peaceful.

The video at the second link above ties together police bodycam footage with surveillance footage and smart phone footage — all time-stamped — and shows the Capitol security police firing on the demonstrators, who until that moment were doing nothing wrong and were simply standing in front of the Capitol in a crowd, chanting “USA! USA!”

Furthermore, the firing began at about 1:07 pm, eight minutes before Trump had finished giving his speech blocks away. The audience to his speech didn’t begin arriving at the Capitol until more than an hour later, when they found doors to the building open and security police welcoming them in.

Thus, the violence, set off by the police, had nothing to do with anything Trump said.

Striped terrain on Mars

12:39 pm

Overview map

Striped terrain on Mars
Click for original image.

Today’s cool image will be a mystery with the answer below the fold. Before you look at the answer, however, you must try to come up with your own explanation for the picture to the right, cropped to post here, that was taken on September 25, 2018 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

What we see in this picture is what looks like a striped terrain, alternating bands of light and dark. What caused the bands? Why the different colors?

The overview map above provides some clues. The white rectangle inside Juventae Chasma near the map’s center marks the area within which this picture was taken, though the picture to the right covers only about a pixel inside that rectangle.

Can you guess what these stripes reveal, from this little information? For this quiz to work you must make a guess, but be prepared to be wrong and quickly reassess your conclusions. Such is the real scientific method, so rarely taught now in schools.
