May 24, 2024 Quick space links

- Video of SpaceX Raptor engine exploding during test today at McGregor facility
This could have been a test-to-failure, or an unexpected engine failure. No further information is known.
- New Glenn engineering dummy rolled to launchpad for more fueling tests
These tests suggest the scheduled launch later this year is actually getting real.
- Short video showing grid fin working as Long March 2D first stage descends
It appears China has done these tests now on five launches, reusing the grid fins at least once. The goal is to more precisely bring the stage down within a confined target zone so that inhabited areas are not threatened by its toxic hypergolic fuels.
- China picks a female Hong Kong police officer as new astronaut
The choice is probably to reward her for helping to squelch pro-democracy demonstrations, while also attempting to pander to the now imprisoned Hong Kong populace.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.

Just once, could someone copy Truax instead of Musk?
Sigh..
The Raptor test (first link) ended at startup, so it may not have been a test to destruction but a test to find the upper limits but resulted in destruction due to surpassing the upper limits.
________________
Jeff Wright,
Robert Truax was half a century ago. What was it about his technology or methods that you prefer over the technology and methods of SpaceX’s engineers?
“Just once, could someone copy Truax instead of Musk?”
I wasn’t familiar with Truax, but reading up on him makes me wonder if Musk is a someone who copied Truax.
“What distinguished him was his visionary sense,”
“He believed space travel could be more affordable and that spacecraft could be reusable.”
“Ultimately, he saw our future in space, and the only way we’re going to get there was to make it affordable,”
https://www.latimes.com/local/obituaries/la-me-robert-truax-20100930-story.html
Mitch S quoted: “‘Ultimately, he saw our future in space, and the only way we’re going to get there was to make it affordable,’”
Truax had tried to start up a commercial launch company in the early 1980s. The Space Shuttle was intended to make access to space both affordable and frequent, capable of lifting heavy payloads to orbit, similar to the intentions of its copycat: Buran. The reality is that the Shuttle was not affordable and was not frequent, and eventually the mass capacity of the Shuttle was reduced, too. (So why didn’t they use the freed-up weight to resume painting the external tank, which may have prevented water from condensing and seeping into the insulation, preventing the Columbia disaster?) Ultimately, Buran only flew once, unmanned, without a payload, and for a brief time. It, too, was not affordable for the Soviets or the Russians to fly a second time, and its true capabilities are unknown. We don’t even know whether it could fly with people onboard.
Truax had difficulty finding investors, because his launch vehicle would compete with the government-subsidized Space Shuttle. Worse, Congress declared that all payloads would launch on the Space Shuttle, a policy that nearly destroyed the U.S. launch industry and greatly helped the Ariane rocket family.
Thank goodness for Peter Diamandis’s Ansari X-Prize, which proved citizen-run manned space is possible, garnering enthusiasm for the concept and leading the way to the commercial space industry we are growing today.
The Space Shuttle’s legacy, however, is that it was so disastrous that the U.S. government decided to replace it with ancient methods of expendable launch vehicles and spacecraft rather than reusable ones. If it hadn’t been for the efforts of U.S. citizens who tried multiple times to start up a commercial launch industry, we would be stuck with the failing SLS-Orion system as our manned spacecraft and the expensive Atlas V, Delta II, and Delta IV, as well as the expensive commercial Pegasus and Taurus launch vehicles.
The world has taken notice that, as Truax believed, commercial space is far superior to government space and that reusability is feasible and economical, allowing for even greater access to orbit.
