Step 1: figure muzzle velocity required to get into orbit. Step 2: make a basic model for air resistance, which feeds back into velocity Step 3: does that feedback converge or diverge? If divergent, impossible. Step 4: make that material I don't know enough aerodynamics to model high speed air resistance well. The way we handle it coming back to earth is to add a layer that will be shed in heat to protect the object. That adds mass.
