SpaceX has recently released a video summary of their May, 2021, launch of the SN15 Starship test vehicle. it’s real, real pretty.

Giggitty!

UPDATE: huh, the video got yoinked. Looking at the SpaceX YouTube video library, it looks like it, might have been just a repost of this video from May:

Their live stream of the launch was buggy due to difficulties in sending the video down live:

The Parker Solar Probe passed close enough to the Sun back in April to arguably be said to have “touched” the sun by zipping through the outermost layers of the solar atmosphere. It took months to get all the collected data back, and John Hopkins Applied Physics Lab  has just released the video below of the passage. The video quality is pretty potato, but it looks like it was a hell of a ride.

Once again, this moment of unutterable awesomeness has been brought to you by hard-nosed engineering rigor. STEM for the won… once again.

As a followup to the large-scale Tirpitz model, if you want a 1/20 scale X-15A-2, these folks can hook you up:

North American X-15A-2

It looks nice, it’s certainly detailed (I haven’t rivet-counted to assure that it’s *accurately* detailed). It’s just… a little pricey.

If they sell out, I might reconsider my abandoned 1/24 X-20 Dyna Soar…

The most recent APR rewards included a CAD diagram I created of the “Disney Bomb.” This little known weapon was created by the British in WWII, but dropped by USAAF B-17’s in the last months of the war in Europe. The reason for the unusual name: in 1942 Disney produced an animated propaganda film on the history and potential or military air power. This film included sequences of the war to come, depicting some kinda-sorta sci-fi thinking. Included here is a bomb with a rocket motor, used to penetrate the reinforced concrete roof of a submarine pen. This gave some British engineers ideas… and they made it reality. The Disney bomb was imperfect, but damned if it didn’t work. Next time someone argues that sci-fi doesn’t actually directly inspire engineers to create the future, remember the Disney bomb.

The YouTube version of “Victory” linked below is pretty awful in reproduction quality, but it’s the best I’ve seen (it was released on DVD some years ago).

Elon Musk tells SpaceX employees that Starship engine crisis is creating a ‘risk of bankruptcy’

Ummm…

“The Raptor production crisis is much worse than it seemed a few weeks ago,” Musk wrote.

UMMM…

Raptor engines power the company’s Starship rocket, with Musk adding that SpaceX faces “genuine risk of bankruptcy if we cannot achieve a Starship flight rate of at least once every two weeks next year.”

UMMM…

A flight rate of once every two weeks within a year for a rocket that hasn’t flown yet? Ahhh… ummm…

The scan quality is terrible. The print quality was probably mediocre. But I get the feeling that the original piece of artwork, produced at Boeing in the early/mid 1960’s to illustrate the interior structure of the Saturn V S-IC stage (built by Boeing back when Boeing could be relied upon to build things like this), was a thing to behold. It was probably in all the colors that an artist working in paint or pen or even colored pencil could produce.

If anyone knows if the original still exists… let me know, and do what you can to make sure it survives. We should do everything possible to preserve the artifacts of our culture at its peak to preserve them against the dark age to come.

If you look back to NASA in the mid-1960’s, it certainly seems like it was an organization filled with people who thought that the future was wide open. Apollo was merely going to be the first step; after some landings would come longer-term “camps” on the moon, with stays of a few weeks in temporary habitats; then would come bases that could be visited by multiple crews. Nuclear powered space stations with artificial gravity. There would be manned flyby missions to Venus and eventually manned landings on Mars; as propulsion systems inevitably grew vastly more capable, manned missions to the moons of Jupiter and Saturn would follow in due course.

By the time Apollo 11 actually landed on the moon, though, it was becoming clear that the future was not going to be what it should have been. As noted previously, the production line of the Saturn V was shut down a year before Apollo 11, not only limiting the possible missions of the Apollo program but ending hope for missions that would expand upon Apollo. Shortly after Apollo 11, it seems that morale at NASA was already in decline as the engineers, scientists, technicians and so on could see the writing on the wall. Not only was Saturn dead, but funding was in decline and it was becoming clear that there was minimal political interest in carrying Apollo forward… the job of beating the Soviets to the Moon was done, and the important scientific work, not to mention the prospect of carrying western civilization to the stars, was not that important to the political class who were far more interested in the “Great Society” spending programs. So in September of 1969 a “Seminar on Manned Flight Awareness” was held at the Manned Spacecraft Center, Houston, to deal with the issue:

The successful lunar landing and completion of the flight of Apollo 11 achieved a national objective in this decade and is a significant milestone in man’s continuing progress in space exploration. Historically, achievements of such magnitude, requiring concentrated efforts over an appreciable time period, are followed by a letdown and general relaxation of the personnel involved. In addition, this letdown may be amplified by a serious morale problem when funding cutbacks are experienced. The result is n decline in the required attention to detailed workmanship which can cause a rise in accident rates and potential loss of life.

To counter these potential morale and complacency  problems in the spaceflight program, this Government/Industry Manned Flight Awareness Seminar is  being conducted. The objective of this seminar is the  maintenance of high quality workmanship through effective awareness and motivational programs. We  intend to do this by outlining NASA’s plans for future  programs and the resources being made available to  successfully conclude these programs. In addition,  executives of various industrial firms deeply involved  in space work will present their views of the future.  In this way we can get the message from NASA Management to the individuals responsible for doing the  work that is vital to assuring a high quality of workmanship in the aerospace force.

Not having been born yet, I don’t have any firsthand information on just what was going on at the time in NASA. However, one thing I *do* have firsthand information on was the end of the United Technologies Center/Chemical System Division facility south of San Jose, California, circa 2003-2004. That company was a manufacturer of solid rockets such as the booster separation motors for the Space Shuttle, booster rockets for the Tomahawk cruise missile, Minuteman ICBM stages and so on. It was a vital part of the rocket industry of the United States. And in 2003-2004, it was *obvious* to everyone there that the company was doomed. Things were going wrong left and right to the point that a lot of us were wondering if it was active sabotage; in reality it was merely management and unions working together to make things as ridiculous as possible. Coupled with the fact that the company could, at best, turn in a profit measured at a handful of millions of dollars a year while sitting on *billions* of dollars of prime Silicon Valley real estate, everyone there knew that the companies time was strictly limited. So, what did the USAF and NASA do about it?

The USAF/NASA told the rest of the United States aerospace industry to *not* hire any of us. We were embargoed from seeking employment elsewhere, at least at companies that received federal contracts. So we stayed on the job. Until, of course, the embargoes were lifted, then we fled like rats fleeing a sinking ship.

It seems that NASA in September 1969 was facing a similar predicament. Everyone there – scientists, engineers, technicians and subcontractors of all kinds – could see the writing on the wall. And when you know that the project you’re working on has a near-term end date, you look for somewhere else to be, preferably before all your co-workers get the same idea. This is sensible, but it’s also a problem. Yes, Apollo/Saturn had a distinctly limited lifespan. But the program still had a number of years left, and it would need the bulk of the staff to stay on the job to make sure that the spacecraft and launch vehicles were finished, maintained and prepared for their missions. If everyone at NASA fled for brighter opportunities elsewhere, the missions still funded would be unable to be completed. So NASA held a seminar that seemed to have the singular goal of convincing people just how bright NASA’s future really was. A space shuttle would be available by 1976 and a space station by 1979… as well as a polar orbit station and one in geosynchronous. A lunar orbiting station around 1976. Nuclear powered inter-orbital shuttles. Manned missions back to the Moon and on to Mars.

It was all wrong. Yes, the Shuttle finally arrived in the early 1980’s, greatly delayed and vastly and permanently over budget, each flight costing one to two orders of magnitude more than originally projected. yes, a space station did eventually arrive… in the 1990’s, handicapped by international politics, small, undermanned, under-capable. None of the rest of it even *tried* to happen. The seminar reads like desperation, or a rah-rah session at some multi-level marketing scheme; I had flashes to scenes in the recent Hulu series “Dopesick” where Oxycontin sales reps are getting the latest BS about how great the next dosage of the pill will be, so go out there and sell more.

*A* future does not mean *A* *GOOD* *FUTURE.*

No. It was the end, and apparently everyone involved could see it.
