Land of dust devils
Click for original image.

Today’s cool image to the right demonstrates that the atmosphere and climate of Mars is truly different in different places. The picture, rotated, cropped, reduced, and sharpened to post here, was taken on July 22, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled simply as a “terrain sample”, it was likely taken not as part of any specific research project but to fill a gap in the camera’s schedule in order to maintain its proper temperature.

I post it today almost to illustrate the difference between this location and the spot where the lander Insight landed on Mars. Earlier this week the MRO camera team released a short movie created by images of the lander taken over six years, showing how the dust around it had changed over time. I noted further how those images showed a very small number of dust devil tracks, which explained why no dust devil every crossed over the lander’s solar panels to clean them of dust.

For the picture on the right, however, there are a lot of dust devil tracks, so many near the bottom that they almost completely darken the ground.

Pushback: Blacklisted doctor gets lawsuit reinstated by higher court

1:25 pm

What apparently passes for medical treatment at the Hennepin Healthcare system
The kind of policies advocated by Hennepin Healthcare system
that Gustilo criticized

Fight! Fight! Fight! Back in August 2021, I reported the horrible blacklisting of Tara Gustilo, a biracial physician from the Philippines, who had been demoted and experienced a $150K cut in salary at the Hennepin Healthcare system in Minnesota simply because she had posted criticisms of the racist Black Lives Matter movement as well as the critical race theory policies, now known as Diversity, Equity, and Inclusion (DEI), that Hennepin was pushing.

In addition to filing a discrimination complaint with the federal government, Gustilo sued, represented by the Minnesota-based Upper Midwest Law Center (UMLC). You can read her lawsuit here [pdf].

That lawsuit however had been dismissed by a lower court. Last week however the Eighth Circuit Court of Appeals threw out that decision, reinstating the lawsuit.

The court’s decision can be read here. The court specifically noted that Gustilo’s right to free speech appeared to have been violated, and that fact must be considered by a jury.

Vast signs deal with SpaceX for two ISS tourist missions

12:34 pm

Depending on whether it gets NASA contractual approval, the space station startup Vast has now signed a deal with SpaceX for flying two tourist missions to ISS.

These two missions expand Vast’s launch manifest with SpaceX, which includes the company’s Falcon 9 rocket delivering Haven-1 to low-Earth orbit and a subsequent Dragon mission to fly crew to the commercial space station. Haven-1 will also be supported by Starlink laser-based high-speed internet.

Axiom, which has flown three tourist missions to ISS and has a fourth planned, is also bidding for the next two tourist slots NASA has made available for ISS in the coming years. It is not clear who will get those slots. Axiom has the advantage it has done it before, but the rumors that it lost money on those flights and now has a cash shortage work against it. Vast hasn’t yet flown, but it is moving fast to fly and occupy Haven-1 next year. NASA might want to give it at least one of those slots to balance the scales.

Hat tip to BtB’s stringer Jay.

More evidence SLS and Orion are on the way out

11:12 am

An article today by a local Fox station in Orlando calling NASA’s decision to fly the next Artemis mission using the Orion capsule as a return to the bad culture that caused both shuttle accidents is strong evidence that the political winds are now definitely blowing against the future of both NASA’s SLS rocket and its Orion capsule.

The article interviews former NASA astronaut Charles Camarda, who expressed strong reservations about NASA’s willingness to make believe the failures of the Orion heat shield on its only test flight could be dismissed.

“The way they’re attacking the problem is echoes of Challenger and Columbia, using exactly the same bad behaviors to understand the physics of the problem,” [former astronaut Charles Camarda] said. “They’re not using a research-based approach.” Camarda worries NASA is pressing ahead with the current heat shields because he says “a lot of the engineers are afraid to speak up, and that’s a serious problem.”

The point is not the article itself, but that a mainstream propaganda news outlet is publishing this perspective. This fact suggests that there is a growing willingness within the political community to end both SLS and Orion, and articles such as this are used to strengthen that narrative. Politicos in DC have a great fear of canceling big projects, and for them to agree to do so requires a great deal of groundwork to make sure the public will accept the decision. Articles such as this one are thus published in the propaganda press for exactly this reason.

In other words, the Washington swamp has now begun its own campaign to cancel SLS and Orion.

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.

Alabama Republican congressman introduces spaceport funding bill to help a non-spaceport

10:00 am

In an example of the typically corrupt behavior of the Washington swamp, Alabama Republican congressman Dale Strong yesterday introduced a bill dubbed the Spaceport Project Opportunities for Resilient Transportation (SPACEPORT) act that has a lot of high-minded goals, but is mainly designed to funnel federal money to local regions. To quote Strong himself:

“The U.S. is the global leader in space, and North Alabama is at the forefront of that effort,” Strong said. “As former Chairman of the Madison County Commission, I worked closely with local city officials and commercial space stakeholders to secure Huntsville International Airport’s designation as the first entry site for space vehicle landings. I understand the preparation, coordination, and support required to safely and efficiently manage space launches and reentries. North Alabama is ready to leverage our unparalleled civil, commercial, and national security space expertise to support space infrastructure projects and the future of space exploration.” [emphasis mine]

Huntsville International Airport is not a spaceport. Giving it cash for this is nothing more than pork and a waste of the taxpayer’s money.

Strong’s bill is merely a proposal, and has been announced I think mostly to give this guy a photo-op. Nonetheless, it shows that we cannot trust any politician to do what they say. The Republicans always run on cutting the budget, but here we have a Republican eagerly proposing we spend money we don’t have in order to provide pork to his district. It is essential that his own constituents tell him in no uncertain terms that this kind of legislation is not what they hired him for. If they don’t, then things in Washington will only continue to do downhill.

Activists sue Texas commission for allowing SpaceX to use its Superheavy deluge launch system

9:45 am

The same activist groups that have repeatedly used lawfare to try to block SpaceX’s operations at Boca Chica have now sued the Texas Commission on Environmental Quality (TCEQ) for allowing SpaceX to use its deluge launch system during Starship/Superheavy launches, claiming that dumping potable drinking water into the ground somehow damages the environment.

The groups — the South Texas Environmental Justice Network, along with the Carrizo/Comecrudo Nation of Texas, and Save RGV — filed the lawsuit Monday after the agency decided last month to allow SpaceX to continue its operations for 300 days or until the company obtained the appropriate permit.

These three groups represent only a very tiny handful of people in the Rio Grande Valley. The people the media interviews from Save RGV always includes the same persons, suggesting that few people in south Texas support it. The “Carrizo/Comecrudo Nation of Texas” in turn is a fake Indian tribe. It no longer exists, and when it did it existed in Mexico, not Texas. Finally, the “South Texas Environmental Justice Network” is simply an umbrella organization created on top of other two to make it appear they have more support than they do.

The real question that local journalists should be asking is where are these groups getting their money for all their lawsuits? I suspect it comes from outside the region, from leftist political organizations whose goals have nothing to do with the environment.

Firefly’s Blue Ghost lunar lander wins its fourth lunar NASA contract

9:32 am

Peregrine landing site

NASA yesterday awarded the rocket startup Firefly a $179.6 million contract to carry six NASA science instruments to the Moon on its Blue Ghost lunar lander, the third lander contract the company has won and the fourth Moon contract overall.

[The four contracts include] three lunar landers as well as one to provide radio frequency calibration services from orbit to support a radio science payload on the second lander mission.

The first mission, Blue Ghost 1 or “Ghost Riders in the Sky,” is scheduled for launch in mid-January, with a landing in the Mare Crisium region of the near side of the moon about 45 days after launch. Blue Ghost 2 will follow in 2026, landing on the lunar farside. That mission will also deploy ESA’s Lunar Pathfinder communications satellite into orbit. Both the second and third Blue Ghost missions will use Firefly’s Elytra Dark as an orbital transfer vehicle, delivering the landers to lunar orbit. Those vehicles will remain in lunar orbit to provide communications services.

This new contract will have Blue Ghost land in the Gruithuisen Domes region, as shown on the map to the right. This had been the landing target for the Astrobotic’s Peregrine lander when it launched in January 2024, but that mission failed when it developed a fuel leak shortly after launch. Astrobotic was able to operate the spacecraft through most of its trip to and from the Moon, but had to cancel the landing.

ESA awards Avio three contracts worth $372 million for its Vega rockets

9:16 am

Capitalism in space: The European Space Agency (ESA) yesterday awarded the Italian rocket company Avio three different contracts worth $372 million to further develop its Vega family of rockets.

The first two contracts subsidize work on upgrading the Vega-C launch site at the French Guiana spaceport as well as developing the company’s planned new rocket, Vega-E.

The third contract is more significant, because it signals the coming end of Arianespace, ESA’s commercial arm. Instead of going through that government-run agency — as ESA has done for a quarter century — ESA simply bought a Vega-C launch from Avio directly, the first time it has obtained launch services directly from a European company. The contract is to place in orbit an ESA climate research satellite.

The end of Arianespace was further signaled today by the announcement that Arianespace’s chief executive since 2013, Stephane Israel, is stepping down. It was Israel who in 2015 discouraged ESA from making Ariane-6 reusable. It was Israel who for years poo-pooed competition and free enterprise, lobbying continuously that ESA should do its launches through Arianespace exclusively.

Now, more than a decade later, ESA has finally rejected Israel’s arguments, and is eliminating the middle-man Arianespace entirely, purchasing launch contracts directly from the rocket companies while having its member nations as well as itself encourage the development of many private rocket companies across Europe.

Chinese pseudo-company launches four satellites

8:41 am

According to China’s state-run press, China early this morning successfully launched four satellites using a commercial rocket, Ceres-1, that lifted off from an off shore launch platform on the country’s northeast coast.

The rocket supposedly belongs to the pseudo-company Galactic Energy, but China’s state-run press did not think this information was important enough to mention, illustrating why I think the company is not real. The satellites were likely communications satellites intended for one of the several giant satellite constellations China is building, but that information was also left out of China’s reporting.

132 SpaceX
63 China
16 Russia
13 Rocket Lab

American private enterprise still leads the rest of the world combined in successful launches 151 to 95, while SpaceX by itself leads the entire world, including American companies, 132 to 114.

Axiom to speed up assembly of its space station

6:59 pm

Axiom's new module assembly sequence
Axiom’s new module assembly sequence

Capitalism in space: In order to be able to fly its space station independent of ISS more quickly, Axiom has rearranged the order it will launch some modules.

Originally, the plan was to attach Habitat 1 (AxH1) first, before the power and thermal module. Now, the on-orbit assembly sequence will start with the Payload Power Thermal Module (AxPPTM), followed by AxH1, an airlock, Habitat 2 (AxH2), and finally the Research and Manufacturing Facility (AxRMF). “The result – free-flight capability after the launch and berthing of PPTM,” [Mark Greeley, Axiom Space COO and station program manager,] explained, “[will allow] us to add modules while on orbit once we have separated from station. Our goal is to ensure a smooth transition from a government to a commercial platform, maintaining a continuous human presence on orbit to serve a community of global customers and partners, to include NASA.”

The AxPPTM primary structure will be built by Thales Alenia Space in Turin, Italy, and then relocated to Houston no earlier than fall 2025, where the integration of the internal structure and systems will take place at Axiom Space facilities.

The new sequence is shown in the graphic above. This change will allow Axiom to fly free two years sooner than previously planned, in 2028. It appears NASA pushed for this change possibly because it considers remaining attached to ISS until 2030 a risk that should be avoided. NASA apparently is increasingly concerned about the state of Russia’s Zvezda module, and fears it might have a catastrophic failure due to the stress fractures in its hull. The sooner Axiom can get free of ISS the better.

This modification also appears to include some major changes from previous Axiom graphics. It appears the airlock module and its solar panels have undergone a major design change.

Below is my present ranking for the launch of the four space stations being designed and built:

  • Haven-1, being built by Vast, with no NASA funds. The company is moving fast, and plans to launch and occupy it in 2025 for a 30 day mission. It will then build its mult-module Haven-2 station.
  • Axiom, being built by Axiom, which has also launched three tourist flights to ISS. Though there are rumors it is experiencing cash flow issues, today’s announcement suggests those rumors might be unfounded.
  • Orbital Reef, being built by a consortium led by Blue Origin and Sierra Space. Though Blue Origin has apparently done little, Sierra Space has successfully tested its inflatable modules, including a full scale version, and appears ready to start building the station’s modules for launch.
  • Starlab, being built by a consortium led by Voyager Space, Airbus, and Northrop Grumman.
