Aah but David, its a start along the lines you and I have been trying to
drum up interest. You gotta crawl before you walk. As you know well,
it's the way to start out in LEO (cheaper launch) and then nudge it into
MEO. I said before, it's gonna happen since it's the obvious solution to
getting to a better orbit. A lot to overcome but there's work going on
now to get there.
Did someone say that the new Delfi satellite will have some thrust on
board or was it a wishful dream on my part??

Thanks Joe.
What an exciting concept.
Having got really enthusiastic, I thought I would roughly calculate how
high one of these little rockets could raise the orbit.
Given that one rocket reload pack has
40 Newtons of thrust
and lasts for about one second
We have 40 Newton seconds of specific impulse.
The mass flow rate is 18.6g in one second or 0.0168kg/s
So.....the ISP (a bit vague here) is around 219 seconds (ave thrust / mass
flow rate / 9.81ms^2)
Which should get a 3.7kg satellite's apogee about..... 40km higher.
So...Not enough for P3E then
Oh well, not so exciting after all. Time for a beer.

Has anyone seen this. I am surprised a shuttle mission permitted this
type of booster. From what I believed, safety concerns prevented most
types of boosters.
