"The incoming shell could be 1) a heat resistant ablative graphite shield able to withstand the 17,000 MPH (27,000 km/h) and 3000 degrees earth re-entry and impact… a rather dubious scenario if you’re importing ice cubes, or 2) the shell could be coated in metal that reacts to ablative lasers aimed from some earth mountaintops. The lazered metal converts to gas, thus decelerating the re-entry to as little as terminal velocity about 200km/hr (120 MPH/hr) through our thick old earth air. Gotta have good aim and miss all the other earth orbiting stuff. How much deceleration can you get out off a metal coated graphite shell? . You can bet it will deflect the shell in all sorts of ways on the way down too. " and why would you think 'throwing' wouldn't involve a machine. If we used a trebuchet would that not be throwing ?
