This question already has an answer here:
Regular spaceship missions are effective but also incredibly expensive. The most discussed alternative of them would be the space elevator, but with our current technology, it isn't possible to construct it yet.
But what about fast acceleration, like shooting a satellite into orbit by a railgun?
Railguns use super strong electromagnetic fields to accelerate things to high speed. They have military application, but would it be possible to shoot satellites to an altitude and at velocity to achieve orbit?
Theoretically, if we can accelerate a body to Mach 23, that MAY be enough to get it into outer space orbit (since this is the lowest velocity to achieve it).
My questions are:
Can we reach required speeds with structures similar to railguns?
Do we know of any materials that can "survive" a quick acceleration to such velocities without disintegrating, melting or exploding into pieces due to atmospheric drag and acceleration forces involved?
