Continuing…
The notion of adding a “docking module” to the Shuttle to allow it to dock with another spacecraft. Here’s one that actually got built and used for docking to Mir and ISS.
Next time: a stretched External Tank & SRBs for increased payload.
Continuing… An idea for added propellant tanks for the rear of the cargo bay. The propellant would feed not the SSME’s, but the orbital maneuvering system engines. This would allow the Shuttle to reach higher orbital altitudes.
Continuing. This time, discussion of possibilities of higher thrust SSMEs including the SSME-150 with an extendable nozzle. Once again this would be for increased payload capability, in particular 32,000 pounds to polar orbit from Vandenburg.
Hey. Hey.
Continuing. This time, discussion of possibilities of swapping out existing Orbiter structures with graphite composites. The advantage would be lowered dry mass of the Orbiter, leading to potentially higher payload performance. This would, presumably, be of interest for USAF launches from Vandenburg, a possibility that Challenger put to bed.

Around three years ago I posted some rather cruddy images of a saucer-shaped nuclear-powered spacecraft that the Chrysler corporation drew up in 1956. At this time a manned spacecraft was a perfectly normal sort of thing for Chrysler to design; their aerospace division was responsible for the Redstone missile and the Saturn I first stage. One of the images was a small scan of the cover of the August-September 1957 issue of “Saucer News.” I finally managed to score a copy of this “fanzine”on ebay a while back and have scanned the cover at high (600 dpi) resolution. The image quality is a bit regrettable, but what can you expect from a 1950’s UFO magazine.
As always, if anyone might happen to know anything more about this design, I’m all ears. Chrysler long ago got rid of their aerospace division and whatever archive it might have had.
I have uploaded the full resolution scan to the 2019-08 APR Extras Dropbox folder, available to $4 and up subscribers to the APR Monthly Historical Documents Program.
One sizable document I’ve scanned for preservation is a Rockwell presentation package from October, 1985, showing a large number of space programs that the company could capitalize on. These included everything from minor mods to the Space Shuttle to major changes… stretching the orbiter, stretching the tank, adding additional boosters. Heavy lift boosters to put SLS to shame; heavy lift SSTOs; small experimental spaceplanes; manned military spaceplanes; space-based weaponry; space stations; space based nuclear power. Figured this stuff might be of some modest interest. So why not, I’ll post little bits of it from time to time.
Rocket Lab is, it seems, planning on recovering and reusing the first stage of their small Electron launch vehicle. The means of recovery is a lot lower tech than that of the Falcon 9… the Electron will pop a drogue ballute to stabilize, then open a parafoil to slow down and drift in the direction of a recovery ship. Before splashdown it will be air-snatched by a large helicopter then flown to the ship. Should be doable; the small size of the booster makes recovery of the entire first stage via this method practical, while Lockheeds Vulcan is, last I checked, only planning on recovering the engines and avionics.
This is of course no threat to SpaceX, which is going increasingly Bigger And Bigger. Still, it will be good to see yet more space launch systems working towards reusability and truly low cost.
On the other hand: no matter how capable Rocket lab gets with future boosters, their choice of launching from new Zealand will be a limiting factor. New Zealand has been since 1984 a “nuclear free zone,” excluding from its territorial waters any ship powered by nuclear reactors. While this would not necessarily seem to exclude nuclear powered spacecraft… why would someone with such a payload risk it?
