Getting a rocket out of the atmosphere

AidanDelli said:

Just for theoretical reasons, I was wondering what it would take to get as rocket out of the atmosphere. I want it to be made out of pre-made motors so I'm assuming O class since that is the highest to my knowledge. I was thinking it would have to be a cluster or dual stage design with the body and fins entirely made out of metal. For recovery, I would assume something along the lines of dual deployment but I'm not sure. I was interested what your guys opinions of this would be and how you would go about accomplishing it. (I am not trying to actually build one, just a random thought I had.)

The atmosphere gets thinner and thinner as you extend into space, so there is no clear definition of where it ends. All earth orbiting satellites get affected by our atmosphere (specifically the mesosphere, thermosphere, and exosphere) , though the amount diminishes with altitude. We do, however, have a definition for space, the Karman Line, at 100km above sea level.

Is the Karman Line what you mean, or is there a specific layer of atmosphere that is the goal to exceed?

getting to so called space is easier than getting into orbit. I think for orbit you are going to need around 17,000 lbs of fuel with ISP of 260. read that some where but it is probably bull.
Also remember if you get to space there is nothing for your motor to push against. (hahaha)
