Title: Cheapest/Simplest possible suborbital rocket.
Post by: FishInferno on 03/16/2017 11:32 pm
Food for thought, how cheaply could one build a sounding rocket capable of getting to space?  Could you use r-candy, or would this require too big of a booster?  For recovery, simply put the recovery charge on a timer to deploy at the appropriate time in the rocket's trajectory (math doesn't lie).

Start by asking these guys maybe.

I thought others did it during the 1990s.

Closer to your heart, perhaps, is Sugar Shot to Space:

https://forum.nasaspaceflight.com/index.php?topic=36487.0

There have been a number of claims over the years for the first amateur flight to space. In the early '60s,  there was a group that claimed to have reached space with a four-stage balloon-launched rocket (a rockoon), each stage a cluster of Coaster Corp motors. Later, Bob Jones claimed to have reached 150 miles, with an entirely homemade rocket, also launched from a balloon. I believe the Pacific Rocket Society, in one of its incarnations, claimed to have launched a rocket into space. ISTR that some of the high-power rocketry folks that launched/launch at Black Rock might have tried.

There were probably others that I have forgotten or never heard about.

Then, there is the issue of exactly what "amateur" means, in this case. Mainly, must the rocket be built from scratch?

Imagine IIRC permeating this entire post....

We have now successfully static tested a short two grain 12" sugar motor

and a second time last month with 3 grains:

Our plan is for a six grain 12" booster with a 6" second stage (the 6" has flown successfully).

Cost for the sugar propellant to reach 100 km in fully reusable rocket is $850

We are planning a 6" to 3" second stage test flight next week to test staging electronics.
