It isn't exactly a puny little firecracker. I don't think you really need to double the size of that, especially since a massive single-stage launcher wouldn't be nearly as practical for reaching further destinations.

Antimony-120 wrote:The reason for the one-stage constraint is that in most sci-fi the spaceships do not need a second stage. In terms of plot this is useful as it means that fuel is the only needed resource, as opposed to fuel and a well (and often custom) designed, precision made part that will only be used once.
It's not a particularly practical setup from a thurst-to-fuel-ratio perspective, but if we handwave that away and suggest fuel is cheap and parts are expensive, it becomes more interesting. I believe the op simply wanted to investigate a practical single stage craft under present technology to see what sort of limitations and options that setup brings with it.
Unfortunatly I don't have the time to investigate, and I'm not familiar enough with the engineering to suggest anything without investigation. But I'll watch this thread closely.

The dramatic problem I see there is rather along the lines of:
«We need to escape that angry alien mob now! Prepare for launch immediately!» - «Alright... check back with me next tuesday.»

ikrase wrote:2: Universal Nuclear Space Shuttle: Powered by a DUMBO or NERVA variant rocket. Is lifting body re-entry vehicle, has dV of 7000-8000. This will be smaller than the STS orbiter. Therefore, it can launch into LEO from the back of the Supersonic/Suborbital Transport, be able to maneuver (which the Space Shuttle can barely do), and then land vertically. This would have no cargo bay, but it would have a flexible pressurized compartment able to take either several people (for space station service, etc) or a bunch of in-pressure cargo (replace the Progress, plus be able to recover equipment.) If delivered into orbit around another planet, it can have fuel for one landing and one takeoff. (Mars, Moon, or Titan under consideration).
