If we had the capability of giving enough momentum to a capsule to fly from Earth's surface to a 'safe' low stable orbit: How high would that orbit be? What initial position, shooting angle and trajectory would you choose? Given that the capsule can slightly modify its own trajectory once in the air. We can set our 'magic gun' up to 6 kilometers over the sea level to avoid the thickest lowest part of the atmosphere and maybe save some energy there. What initial (and final, once in orbit) speeds will the capsule need to be given at the surface? Given that there is no extra acceleration once the capsule is "shot", only fighting air drag and gravity on its way up, rotating around its axis like a bullet; while flying at supersonic speeds and slowing down. Let's say the capsule is a very aerodynamic, supersonic bullet like shape with 2m in diameter, 10m long and weighs around 5-10 Tons. How much temperature increase would it go through due to impacts of air particles at supersonic speeds? Could we manufacture any materials that support those temperatures? In which particular configuration arrangement would they operate best to dissipate the heat? If so, what materials should shell the capsule? A source background would be appreciated.
