Hi Bill,
It is certainly refreshing to see you, David, Joe, etal discussing
new ideas, and methods, designs for our future hamsatsKudos to
Peter ESSA for their efforts..
I'm 90, and old man, but it gives me the same thrill I got 30 years
ago when I made my first amateur satellite

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
David;
There are some much bigger motors! Ask the Level-3 rocketry folks!
Anyway a cluster of medium sized motors could be fired individually as
required to raise altitude. I would think that SRB's would be more
reliable and safer than hypergolic used on previous Oscars. There would
of course
How would attitude be controlled so the thrust is in the correct direction?
Spin stabilization about the maximum moment off inertia axis is probably the
best choice. This would require a magnetic torquing system.
Another issue is the thrust needs to be directed through the spacecraft's
Pretty cool idea! Of course Aerotech sells much larger engines with
hundreds of newton-seconds of total impulse, and somewhere close to 100
pounds of instantaneous thrust when it is first lit! And even if it stays
in LEO, this certainly prolongs its life...
What I wonder about is how the
I have developed the perfect solution;
A gatling gun type canister for the rocket motors would solve all of
your objections per below:

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.
