Title: Ways to improve "HD camera attached to weather ballon" space experiment?
Post by: scienceguy1200 on 14/12/2011 21:56:26
Its the experiment where you attach a camera to a weather balloon until it reaches the edge of space/stratosphere. I really want to do it but im afraid i wont come off as original if i just straight copy someone else's methods. Is there any ways to could improve it to make it my own? Perhaps make it more effective or perform a test while its in/near space?

Thanks!

Here is another link about a paper glider attached to the weather balloon.

You need to decide what your system goals are.  Just reach space?  Photos from above the clouds?  How long do you want it to be in the air?  I assume you can add a pressure regulator to keep the balloon from bursting for a while, but you may want to add some kind of a self-destruct then.  I suppose, even so, the gas will slowly leak out of the balloon, so it would have a finite life in space anyway.  You might even want to incorporate a refilling method like a small CO2 cartridge filled with H2.

Modes for controlled descent?

It looks like most of the balloons use hydrogen rather than helium, which should give you the maximum lift.

Yes, my main goal is to reach space (as much as possible anyway). I have also considered the idea of maybe just leaving something in space. (just so i could say there is something in space that belongs to me or what not). I've been contemplating using a homemade rocket, either for launching the camera even further once it at peak altitude or using it as the object to leave there. I don't foresee building the rocket to be difficult but i can't think of anyway to ignite it 18+ miles in mid air air from the ground. Your ideas are great too btw!

The USA sets the space-boundary at 50 miles high while the FAI defines space as starting at a height of 100 km.

A rocket which could travel tens of kilometers would cost a fortune (and require a flight plan).
