That\'s the other thing; it\'s not at all certain whether his school actually will fund anything like this.

I doubt it. Given the world record amateur rocket inly reached a peak of 3420mph(Vs the necessary 17,500ish mph) and altitude of 72 miles. This would have been done by some seriously educated people with a huge budget I wouldn\'t be surprised is near or over a million dollars. I don\'t think a bunch of teenagers funded by a couple bake sales is going to manage a rocket that would need to be some 25-50 times the size.

You could probably build something simple that could reach high in the atmosphere, but building a rocket that can orbit is just out of the question.

I admire the optimism but you have to be realistic.

We are being realistic. Two men in New Zealand we able to launch a sub orbital rocket, we should be able to. If we can\'t find a way into orbit, then we will just go for suborbital.

That\'s the other thing; it\'s not at all certain whether his school actually will fund anything like this.

They probably would, but we don\'t actually want them to fund it all. We would rather have some companys sponser us.

I disagree. I say good for him! GO! I wish my school would give me funding for something like that. They\'d probably look at me like I was crazy...

Some people do look like we are crazy, but others look at us and think we can do it. We have the teachers and the willpower, all we need is the money and the stuff to make it.

We could try at least.

Well, I could go into a suborbital flight if I had that.

The main problem is developing the engines for the rocket, and having a good enough plan to get the money. Amagine being the first group of under 18 year olds to get into space. People would pay to be a part of that. Its also not about the school funding us. The school will only be paying for the engine tests.

And how are you going to get something like 100,000 dollars before you turn 18?

Because I hate having people being better than me, I need to now compete with you on that. On my own funding. Somehow.

Basically, kickstarter might work (I\'ll link it to the main person doing this as I am not the leader, just an expert on how rockets work, that way I don\'t have to take the blame if something goes wrong!!!). Our original idea was to have a hybrid rocket for the main rockets, but we might be using a Liquid rocket design. Both can be throttled. Solids are out of the question as they are pre fuelled (basicly explosives that haven\'t gone off yet).

Good luck then, even though we will need it...

IDEA TIME

Make a balloon

Strap a rocket to it

Balloon goes up

Launch when you\'re already many kilometers up.

If this works, I think it may be the only chance you would have of getting into space, orbit is just wishful thinking unfortunately. But still:

If the balloon is strong enough to not burst, you could get up fairly high. If you replicated what was done in the video posted earlier, you would already have 30.78 km behind you, a little under 1/3rd of the way to space. However, a rocket that can climb about 70 km/43 miles would be VERY hard to build.

But of course, it\'s no guarantee you would be able to keep the rocket stable when launching from a balloon...

I would find a way to hang the rocket by the nose from a fairly long cable. If you could find a way to ignite the engine and then get the balloon out of the way, it should be pointed more or less straight up correct?

If only KSP physics applied, and the parachute would disappear once you got going.

I would suggest a computerized decoupler, that drops the parachute at an angle, then the rocket rectifies and launches. The parachute falls away from the rocket, and the rocket continues on its merry way. Look at Flixx\'s video on that parachute missile thingy (I forget the name.).

Or, make a square frame and attach balloons on each corner and hang the rocket in the center. The rocket exhaust might explode the balloons, but you don\'t really need them anymore.

The only problem I see there is that you\'re going to need a system to ensure that the platform stays nice and level.

I just hope you all keep it nice and legal.

First major problem is funding, second is legal, and third is building the damn thing.

Legal probably comes before funding. No one is going to fund your project if you can\'t legally pull it off.

Also, if you\'re wanting to reach orbit, we\'re talking international law, here.
