The goal is to use their centrifuge-like launch mechanism to catapult objects like satellites out through our atmosphere, necessitating only a small second-stage burn to fine-tune their position.

Previously, the moon’s gravity could only be simulated for a few seconds at a time at NASA's zero-gravity research facility using a centrifuge, or for about 20 seconds during parabolic ...
