Re large non-commercial rocket launches, it's worth having a watch of this if you haven't ever seen it before:

I can't help wondering how they would have got if it hadn't been for the 'payload'

In free fall (including orbit) there is no overall effect of gravity.
I can see how an amateur rocket can achieve freefall, but I can't imagine one getting into orbit anytime soon.

Out of this world: British teddy bears strapped to helium weather balloon reach the edge of space
By Andrew Levy and Claire Bates
Created 10:56 AM on 04th December 2008

It's not often that Britain can claim a win in the space race. But these teddy bears drifting nearly 20 miles above Earth have become the first soft toys to take part in extra-vehicular activity (to use correct NASA jargon) at such an altitude.

If my rocket launched to go into space, will it burned because of atmosphere and it's velocity?

If your rocket is not going very fast then it won't burn up on the way down.

Frankly, I doubt your rocket will reach space or any where near it so you can stop worrying! :D

You've just spoke if the rocket could reach space. You're confusing!

How many fuel (solid) do I need to make my rocket enter the space?

Nauful: you really need to spend some time researching rocket science, not asking vague questions on this forum.  No one here is going to design your rocket for you.  For example, asking how many(?) solid fuel boosters you need is meaningless without knowing how much mass you want to propel, how powerful your boosters are and how long they will burn for.

I'm sure that we're all very interested in your experiment but you just can't get the detailed answers to the questions you're asking here.

Hey hey, do you remember about the first man reach space? Yes, gagarin. The rocket just flied at 327m altitude, and it's called REACH SPACE!
Whereas, space = 100 km altitude.

How with it!?

Sorry for my bad speak

Are you guys posting out of sync or something?
 This thread has started to read like a Two Ronnies sketch.

I'd just like to know where you are going with this thread, Naufal. It's confusing me.
