Accelerating Spacecraft on Surface

If you accelerate spacecraft on the surface of the Earth to 11.2 km/s, the spacecraft will experience tremendous atmospheric drag and aerodynamic heating.  The spacecraft is likely disintegrate between the accelerating force and atmospheric drag and the wreckage will be completely burned out from aerodynamic heating.   Many meteor enter the Earth's atmosphere at the speed of 10-20 km/s, and the majority of meteors disintegrate and burn out completely before they ever reaching the surface.

​

On the Moon, however, the atmosphere is practically negligible.  The moon's atmosphere is a thousand times thinner than an ultra-high vacuum chamber created on the Earth.   Central Japan Railway Company developed 420-ton Magnetic Levitation (MAGLEV) train which operates at 600 km/hour, and similar electromagnetic acceleration method can be employed to accelerate 1 ton spacecraft to 2.4 km/s.   Continue
