[amsat-bb] Re: Model Rocket Booster Engine for Picosatellite

[Alan P. Biddle]

Trevor,

The key part is that it was a manned mission.  The complexity of the safety
paperwork, let alone the mission, jumps because of that.  Pyrotechnics of
any sort are always an issue, but much less when the mission only involves
hardware.

There are several CubeSats being developed that will carry thrusters, for
example Delfi-n3Xt

The safety concerns you mention relate to satellites fitted with
conventional rocket fuel motors. 

The Delfi-n3Xt approach uses nitrogen as the propellant and there are other
approaches that would also be safe to fly.
