Just dig & build reactors for energy, naturally taking the gems in the ground. Also take the nono-chips for "science" and put some into packet speed - build a FEW more for research to increase energy efficiency. The moon is "dig-able", just 25x times instead of 3, so takes longer (hence the need for better packet speed), take the "easy" white gems too. You should easily be able to "open" the moon before the drones escape.
