This reminds me of some of the discussion that went on in sci.space
about 16-17 years ago about the smallest rocket that could put either
1 oz or 1 kg into orbit. It was the first time I'd heard of ring laser
gyros. The discussion veered off into how many model rocket engines
would be needed. I kept the printouts for several years.


I can't find it now, but a few weeks back I stumbled on someone trying
to do that with a diminutive multistage rocket out on the web.
I think it uses pressure-fed hypergolic fuels, and is around 15 feet
long IIRC.

I remember the thread Scott refers to. IIRC, there is an amateur
group out in CA that is using that as its baseline since the
supersonic milestone by amateurs has been met. Spaceflight is
the next amateur milestone.
