- Stoke Space touts another video of a 30-second static fire engine test of its multi-nozzle Andromeda upper stage rocket engine
Apparently the test destroyed the camera, though it did its job. Stoke seems to be closing in on getting that reusable upper stage with its very radical design ready for launch.
- NASA uploads the directive that approved the return of Starliner unmanned [pdf]
A lot is redacted, and the rest really doesn’t add anything to what we already know, as far as I could see.
- China agrees to carry Pakistani astronaut to its Tiangong-3 space station
China has very few substantial partners in its lunar base alliance, so this deal is to highlight one.
- Rocket Lab touts its new “flatellite” satellite design for launching large constellations
It is designed to be built quickly in an assembly-line manner and launched stacked to maximum the number on each launch. The company provides the satellite basics, all a customer need do is add on its own instruments, whether for communications, remote sensing, or whatever.
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. from any other book seller, or direct from my ebook publisher, ebookit.
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

Were you traveling 88 mph?
Blair: It’s called old age. Fixed and thanks.
A question: Why are the sections of the Commercial Crew Program Directive blacked/redacted out?
Is any of this classified?
Are there trade secrets being revealed?
Chris asked: “Why are the sections of the Commercial Crew Program Directive blacked/redacted out?”
This is a good question. The largest redactions occur in the rationale (reasoning) section and the decision section. This limits our knowledge of what they decided and why they decided it.
“Is any of this classified?”
It does not look like classified information, but then that is the point of redacting classified stuff. It is possible that there are International Traffic in Arms Regulations (ITAR) issues, which would be considered national security issues, but there is not enough context to be able to say that there is any classified material in this document.
“Are there trade secrets being revealed?”
Possibly, but the shortest redacted sections could reference the thruster failures. Since the reference to the helium leaks is not redacted, the leaks do not seem to be the reason for the redactions, but there are no references to the thruster problems, making me think that this topic is at least part of the redacted text. We already know that the thrusters had problems, so why they may have needed to redact that part is a mystery to me.
What I noted in this document is that the Commercial Crew Program and the Program Control Board decided that putting the two astronauts in makeshift seats on Crew-8 Dragon was safer than returning them aboard the Crewed Flight Test Starliner. It also appears that they intended for the two astronauts to be unsuited, should they have needed the Crew-8 Dragon for an emergency evacuation of ISS after Starliner departed and before Crew-9 Dragon arrived. They must have thought that Starliner is very unsafe.
