@soverato3 It is exceptionally hard to do, it has never been done before even by professionals.

@baguazhang2 Rockoons have been around since the 1950s, so lots of people "beat you to it."

@eggaweb Model rocket engines are not efficient or large enough to get into orbit. Even from a balloon at high altitude, you would need thousands of pounds of rocket to get orbit. Orbit is much much harder than space, because you need to attain more 17,500 mph of horizontal velocity. That is very hard, even without any atmospheric drag or gravity loss!

That's pretty cool. This was my exact same idea, and it looks like someone beat me to it. Not being such a radical idea in the first place, I suppose that's expected though.

@eggaweb thats exactly what i try to do!! i already build a liquid fueled rocket engine and a rocket i only need hydrogen for the balloon, more stages and a way to control the rocket from the ground.... it sounds pretty easy...

makes sense
-
@eggaweb thats what i want to do but laws say under 4 pounds but i doubt if you get something into orbit you will be anything less than a star lol
-
Very interesting although it would have been nice to see more footage of the rocket flight.

duurrrrrrrrr
The biggest benefit is that you overcome most of the atmospheric friction.
I would like to see someone (perhaps myself and some friends) build a multi-stage rocket using large clustered model rocket engines to launch a small satellite into orbit from a balloon.

I like the idea of launching from a balloon rig. It would reduce air friction greatly at the start of the launch, increase fuel/altitude efficiency, and if you could get a 10kg payload to 50km with balloons before launching, Earth's pull on your payload would be down to 98% of the surface pull! (That first 2% is the toughest part, ya?)
