Today’s blacklisted American: Teacher fired in retaliation for speaking out at school board meeting
Blacklisted for opposing her school from giving porno to kids
They’re coming for you next: Brenda Danielle Reprieto, a substitute teacher in Georgia, was fired the day after she spoke out at the Cherokee County School District’s (CCSD) school board meeting, publicly criticizing the board for its policies.
Reprieto attended the meeting both as a teacher and as a parent of one of the district’s students. The topic of controversy was the porno that the school board was allowing in its elementary school libraries — for little kids to read — that was so vile the school board’s chairwoman, Kyla Cromer, would not allow it to be read aloud to adults. It was also considered too obscene for the parent, Chelle Brown, to email the text to the board members. As Brown noted at the beginning of her presentation, all her emails bounced because, as she noted “the content was so vulgar.” Watch her get cut off by the board:

India’s first private satellite manufacturing facility opens
Capitalism in space: At a ceremony today that included officials from the government, the private commercial company ANANTH opened India’s first private satellite manufacturing facility.
Located at Karnataka Industrial Area Development Board Aerospace Park, Bengaluru, the new establishment is equipped with clean rooms for spacecraft sub-systems manufacturing and is large enough to cater to four spacecraft simultaneously.
This unveiling is part of India’s effort to transition from a government-built space effort to one run by the private sector. In the past all satellite construction in India was designed, managed, and owned by India’s space agency ISRO. This facility will now take over that function, and do so not only for ISRO but for any private company that wishes to have a satellite built.
A rock stows away on Perseverance
Click for full image.
Since early February the Mars Rover Perseverance has been toting with it a small rock in its front left wheel, as shown in the image to the right, cropped and reduced to post here and taken by the rover’s left hazard avoidance camera on February 6, 2022.
From an update today by the Perseverance science team:
Back on sol 341— that’s over 100 sols ago, in early February— a rock found its way into the rover’s front left wheel, and since hitching a ride, it’s been transported more than 5.3 miles (8.5 km). This rock isn’t doing any damage to the wheel, but throughout its (no doubt bumpy!) journey, it has clung on and made periodic appearances in our left Hazcam images.
You can see the most recent photo of the rock, taken on May 26, 2022, here. It is very clear that the rock’s repeated tumbling inside the wheel well has worn away its sharp edges as well as reduced its overall size. Given enough time its surface could even become somewhat smooth.
As the update notes, when this rock finally drops off it will create a potential mystery for future geologists, who if they are not aware that Perseverance moved it, will wonder how it got where it was, being geologically out-of-place in its new location.
NASA awards Axiom & Collins Aerospace contracts to build spacesuits
Capitalism in space: NASA yesterday awarded separate contracts to two different companies, Axiom and Collins Aerospace, to build spacesuits for its astronauts, either when they do spacewalks in space or when they are exploring the lunar surface.
The contract enables selected vendors to compete for task orders for missions that will provide a full suite of capabilities for NASA’s spacewalking needs during the period of performance through 2034. The indefinite delivery and indefinite quantity, milestone-based xEVAS contract has a combined maximum potential value of $3.5 billion for all task order awards. The first task orders to be competed under the contract will include the development and services for the first demonstration outside the space station in low-Earth orbit and for the Artemis III lunar landing.
Each partner has invested a significant amount of its own money into development. Partners will own the spacesuits and are encouraged to explore other non-NASA commercial applications for data and technologies they co-develop with NASA.
More information can be found in each companies’ press release, located here (Axiom) and here (Collins).
These commercial contracts replace NASA’s own failed effort to make its own Artemis spacesuits, which spent fourteen years and more than a billion dollars before being abandoned by the agency because wouldn’t be able to deliver anything on time.
The contracts also continue NASA’S transition — as recommended in my 2017 policy paper Capitalism in Space [pdf] — from a failed space contractor to merely being the customer buying products from the commercial sector. The result is we now have a vibrant and ever growing private space sector with products available quickly and cheaply not only for NASA, but for others. The Axiom press release illustrates these facts with this quote:
The Axiom spacesuit is key to the company’s commercial space services. This new NASA contract enables Axiom to build spacesuits that serve the company’s commercial customers and future space station goals while meeting NASA’s ISS and exploration needs.
SpaceX wins more NASA manned flights to ISS
Capitalism in space: NASA has now announced that it is buying five additional manned missions to ISS from SpaceX, beginning in ’26.
This new contract is in addition to a February ’22 NASA award that purchased three more Dragon flights.
After a thorough review of the long-term capabilities and responses from American industry, NASA’s assessment is that the SpaceX crew transportation system is the only one currently certified to maintain crewed flight to the space station while helping to ensure redundant and backup capabilities through 2030.
The current sole source modification does not preclude NASA from seeking additional contract modifications in the future for additional transportation services as needed.
The press release repeatedly makes it clear that NASA very much wishes to buy tickets on Boeing’s Starliner, but until it is declared operational it must give its business to SpaceX. Once Starliner begins flying, NASA will then buy seats on it and alternate between the two companies. Until then however this new SpaceX contract guarantees NASA enough flight capacity to keep ISS occupied, even if Starliner gets further delayed.
Regardless, Boeing has once again lost business to SpaceX because its Starliner capsule is not yet ready. In the long run this contract means fewer total flights for Boeing to ISS, which means less profits.
MAVEN returns to full operation
NASA announced yesterday that engineers have finally completely restored its Mars orbiter MAVEN, after a three month period when the spacecraft was in safe mode due to an attitude control problem.
To fix the problem engineers uploaded new software that allowed the spacecraft to determine its orientation in space not from its onboard inertial units, but from locking onto stars in the sky.
All instruments were healthy and successfully resumed observations; however, the spacecraft was constrained to pointing at the Earth until testing of all-stellar mode was completed, so the instruments were not oriented as they normally would be during science operations. Nevertheless, some limited science was still possible, and MAVEN even observed a coronal mass ejection impact Mars less than two days after the instruments were powered on.
Moreover, for some parts of the year it will still need its inertial units, so a fix for those time periods is still required.
Regardless, MAVEN can now resume acting as a communications relay between the Earth and the rovers on Mars, which for the past year has become its prime mission. While both rovers can communication without that relay, it is often necessary depending on a number of factors, and it also provides redundancy and a greater communications capacity.
Ursa Major announces new rocket engine to replace what Russia previously provided
Capitalism in space: The new rocket engine company Ursa Major yesterday announced a new more powerful rocket engine, dubbed Arroway, designed to replace rocket engines that Russia had been selling.
Arroway is a 200,000-pound thrust liquid oxygen and methane staged combustion engine that will serve markets including current U.S. national security missions, commercial satellite launches, orbital space stations, and future missions not yet conceived. The reusable Arroway engine is available for order now, slated for initial hot-fire testing in 2023, and delivery in 2025.
Notably, Arroway engines will be one of very few commercially available engines that, when clustered together, can displace the Russian-made RD-180 and RD-181, which are no longer available to U.S. launch companies.
Arroway could replace the RD-181 engines that Northrop Grumman uses on the first stage of its Antares rocket. Both engines are comparable in size. However, with Arroway available no sooner than ’25 it still will leave a gap, since right now the company only has enough stock on hand to launch two more rockets, both of which should launch before ’24.
Arroway is also about half as powerful as Blue Origin’s BE-4 engine, so if ULA wishes to use it in its Vulcan rocket a major redesign would be required.
Either way, Ursa Major is demonstrating here again the value of freedom and competition, as well as the foolishness and negative consequences of Russia’s invasion of the Ukraine. In response to the international sanctions against it, Russia blocked future rocket engine sales to the U.S. Not only did that not get the sanctions lifted, Russia is now losing that U.S. business, as other American companies are stepping up to replace it.
China launches nine satellites for commercial data constellation
China today used its Long March 2C rocket to launch the first nine satellites in a commercial data collection constellation.
Owned by GeeSpace, a subsidiary of Geely Technology Group, the satellite constellation will be mainly used to research and validate technologies, such as travel services of intelligent connected vehicles, and vehicle/mobile phone and satellite interaction. It will also provide data support for marine environmental protection.
The leaders in the 2022 launch race:
22 SpaceX
17 China
7 Russia
3 Rocket Lab
3 ULA
The U.S. still leads China 31 to 17 in the national rankings, and the entire world combined 31 to 27.
