1950's Spaceships

[Robbo]

Hello all,

What are some ways to model hypothetical spaceships ca the 1950's using Spaceships and its supplements? I'm looking at chemical and atomic rockets. Is the TL 7 or 6 (or 6+1)? Any sources or advice would be appreciated.

I would use TL 7, with a little bit of TL 8 sneaking in. Remember that in the 50s (like every other period) futurists thought every current trend would continue indefinitely, but nothing profoundly new or society changing would be invented. See the 20 lane mega-highway with atomic powered cars taking men to their jobs feeding punch cards to computers, while the lady of the house stays at home in her sythetic fiber dress and hoses down the plastic furniture.

My source materials are all at home, so I may be off on details.

For chemical rockets that actually were operational during the 1950s, halving the delta-v is close-enough for lox-kerosene or lox-alcohol. The chemical rockets in space are hydrogen-oxygen rockets, and are close-enough for some of the wilder speculations (eg. liquid-ozone-flourine of all things).

For nuclear rockets, designers in the 1950s were very optimistic. The Ragnarok-class from Warships and Space Pirates is listed as GURPS TL8, but is based on a 1961 concept that was planned to be operational by 1972. The Enceladus-class from Exploration and Colony ships is based on the blue-sky ideas of the original Project Orion team for a ship that could be operational in the mid-80s but is listed as GURPS TL9. The Odyssey-class from the same book is a version of the Discovery One from 2001: A Space Odyssey.

I don't think there's currently a module for a high-thrust nuclear thermal rocket that can lift off from Earth's surface. That would probably be a hard-science TL9 design technically, but most of the hard-science designs are based on work started in the 1950s.

Maybe the nuclear saltwater rocket with a very cinematic disregard for radiation?

The nuclear saltwater rocket is already considered to be cinematically efficient. You might tone down its risky side effects (ie, Volatile system and fuel, dangerous exhaust)... or maybe not. In fact, I think a 1950's-era cavalier attitude towards radiation fits perfectly with it, even if the engine itself is potentially quite dangerous.

In other words, you can just make anything up, really, using your unobtanium of choice, or just say that typical 50s-era rockets work a heck of a better than they ever did in reality.

On the contrary, I think limited TL9^ to TL10^ is a fine fit for 50's-era "hard" (but optimistic) sci fi. At the time, they understood the theoretical limits of engines, but they didn't yet know the limits of engineering - they thought these hyper-efficient nuclear drives would be available within 50 years, along with Fusion reactors and flying cars. I suppose you could call that TL6^ or TL7^... but why reinvent the wheel? The equivalent engines are present in the Spaceships series, just far ahead of where 50's sci fi thought they'd be. Likewise, the weapons of choice for these craft tend to be Lasers, Particle Beams and Missiles; again, TL 9-10 is an appropriate fit. Just say that they are limited in computer technology for whatever reason. This is actually pretty standard, even in modern science fiction like Star Trek (admittedly space opera rather than hard sci fi) which has FTL travel and matter<->energy converters, but no cell phones or internet.

What about the program where they secretly gave pregnant women radioactive iodine isotopes? Yeah the '50s attitude toward radiation pretty much allows salt-water rockets to take off every hour from every major city's downtown spaceport.
