If we are to ever reach beyond our own planet, possibly colonizing asteroids and Jupiter’s moon Europa, we need a better propellant system. Rocket scientists recommend nuclear power.
Given all the stars, galaxies and what we know about the laws governing reality, how many planets are there in our observable Universe? “Stuff your eyes with wonder, live as […]
Planetary Resources isn’t the first company formed around the mission of extracting valuable metals from the asteroid belt, but it may be the first one with some real investor belief and funding behind it.
Dr, Michio Kaku: Sadly, the US government will no longer boldly go into space. Its up to private enterprise to now pick up the slack and it appears that is exactly what its doing.
