RE: NASA is back on track to colonize the moon, by destroying some grains of moon material brought back by Apollo 17.

This can help a little but I would focus more on exploring the moon via drones first. Send robots to the moon and have them study the surface and then send some machines that can drill into the moon to see what is hiding inside of the moon as well. Now, I wonder who owns all of or different parts of the surface of the moon, the non-atmosphere and no air space around the moon, the mountains, the valleys, caves, the non-existent oceans, and especially the inside parts of the moon.
