Prior to Challenger, one piece of technology that was often touted as something that would be deployed by the Space Shuttle was the “beam builder.” This was a mechanism that would take rolls of aluminum “tape” a millimeter or less in thickness and automatically chop, bend, deploy and weld said aluminum into truss structure beams. These beams would be arbitrarily long… useful for building all manner of things, from space stations to radar satellites, on up to solar power satellites. The technology got fairly far along… but once Challenger exploded, the idea of actually using the shuttle to build vast constructs in space kinda vanished, with ISS being the only example of that. And in the case of ISS, very little actual “construction” was carried out, instead the ISS was simply assembled, with parts like the solar panels deploying rather than being built.

But while it lasted, beam builders featured in a lot of concept art, such as the one below depicting a beam being extruded from the Beam Builder in the rear of the Shuttle cargo bay. Irritatingly, I’ve misplaced the book I scanned this from and cannot immediately confirm who to credit it to.

A Russian surface to air missile recently failed rather spectacularly, turning around quickly in flight and seemingly tried to go home.

This sort of thing is not terribly unusual. Here’s a Saudi Patriot missile taking a detour:

Recently sold on eBay was a display model for a vehicle labeled “SIPS.” No other data was available. However, this appears to be an upper stage modification for the LIM-49 Spartan surface-to-air anti-missile missile. Which suggests that the first “S” in “SIPS” standard for “Spartan.” Perhaps something like “Spartan Integral Propulsion System” or some such. However, this seems to appear to be a complete vehicle…. the very large first and second stage motors, as well as the warhead section, *appear* to have been replaced with a new, small booster with fins. Perhaps this was meant to test the third stage of the Spartan… or perhaps it was meant to be a way to find some use for the Spartan third stage after program cancellation, as some sort of scientific test vehicle.

The other photos from the ebay auction have been uploaded to the 2022-06 APR Extras folder on Dropbox for Patrons and Subscribers.

The diagram below shows the complete Spartan missile.

HOTOL (HOrizontal Take Off and Landing) was a British Aerospace concept for a single stage to orbit airbreathing launch vehicle, originating in the mid 1980’s. It was a stellar example of aerospace optimism; like its contemporary the X-30 National Aerospace Plane, it relied on a propulsion system of spectacular complexity and stunning lack-of-actual-existence to function. As originally conceived it was supposed to have an RB545 engine; unlike the X-30’s scramjet engine, the RB545 was an air breathing rocket engine. Liquid hydrogen would be used to liquify incoming air, a portion of which would be turbine-fed into rocket engines to burn with the hydrogen. Due to some amazing bureaucracy, the engine was slapped with the “Official Secrets Act” which meant that it was so amazing that it had to be classified… so classified that it basically couldn’t be worked on. Genius! Whether it would have actually worked any better than NASP’s scramjet is anyone’s guess. In the going on forty years since the RB545 was dreamed up, it obviously hasn’t driven an aircraft to orbit. Or, it seems, off a runway. Like the scramjet, it *might* work, if only the development effort was properly funded and allowed to work through issues, rather than starved and throttled.

The early HOTOL configuration shown here would have taken off using a ground trolley in order to save on landing gear mass. The vehicle was nominally unmanned, though crew and passengers could be installed in a module in the cargo bay, located well aft. One problem the configuration had was substantial center of gravity and center of pressure issues, driven by the long, slim fuselage filled with sloshing and emptying hydrogen tanks. As memory serves, this remained a problem throughout the design lifetime of HOTOL.

I’ve just made available to subscribers and Patrons at the $11 and up level a mid-1961 Honeywell booklet describing the space projects they were involved with at the time.

While not a detailed technical design document, this illustrated bit of PR is nonetheless interesting as it shows the sort of thing that aerospace companies would produce Way Back When in order to inform and enthuse the public. Modern aerospace companies would probably produce this as a web page or a PDF, which just doesn’t have the same impact. Of course, *this* one is being distributed as a PDF, but moving on…

HA! Found ’em. Well, there’s the better part of a day’s theoretical productivity flushed down the obsession s-hole. I’d *swear* I’d shared these before, but I can’t find evidence of that. Either I imagined it or I did so elsewhere. It *may* have been in support of “Man Conquers Space,” many long years ago, an exercise as dead and buried as the dreams of manned missions to Neptune by 2000. Anyway…

Pages from a Convair report on Post-Nova launch vehicles, 1963. This was for a contract to NASA-Marshall, and explains what the future of space launches looked like from this golden age, before Viet Nam and especially the “Great Society” program spending brought NASA budget and its dreams of an actual future post-Apollo crashing down.

This particular report does not have the authors listed… but other related reports do. This has Krafft Ehricke all over it. It’s the sort of space optimism that he excelled at, and that a better world would have gotten.

Three models are examined… Conservative, Intermediate and Ambitious. Even the Conservative model has manned missions to Jupiter before 2000 (the thinking behind “2001” was not so far off… for the time), while the Ambitious model has long term Jovian bases by 1996 (followed by annual supply flights), manned missions to Titan bases by 1999 or so and manned flybys of Uranus and Neptune by the early/mid 1990s. A permanently manned Mars base by 1987 or so.

Instead we got… hmmm. What’d we get? Facebook? Twitter? Weirdos and vanity and decay?

Along the same lines, two charts shown by Ehricke a few years later, showing what the future of spaceflight held:

The likes of Ehricke had a much higher opinion of Mankind than history has borne out.

If this sort of thing has been interesting, why not subscribe to the or the APR Patreon or the APR Monthly Historical Documents Program. ? Or just hit the tip jar?

Do it.

DO IT.

Much can be said derisively about the Boeing Starliner, but you can’t deny that it looks spiffy on-orbit.

Starliner is not yet ready to fly passengers to ISS, certainly not paying private tourists, still, it’s a step in the direction of granting the US redundant flight capability.
