  • The ideal situation would be to have something like this on fx. the moon, which would have no atmosphere and could easily deliver resources to mars and other planets, though this I believe would be far into the future.I think the obstacles are more than just engineering...60,000g will play havoc with my lunch, and friction at 11m/s is likely to vaporise most things we launch.
