It may be tempting to use our nuclear warheads to save the planet from rogue space rocks instead of pointing them at each other, it would be a waste of perfectly good nukes.

Buckle up steampunk enthusiasts, it turns out that not only are steam-powered space probes possible, they might be perfect for hopping between comets and asteroids on research and mining missions.

Asteroids and comet brought our planet water and the chemical precursors for life. But could they have also given rise to our continents and help set plate tectonics in motion?

Scientists and engineers are slowly but steadily preparing to protect us from an incoming comet or asteroid despite the media's coverage of their efforts as anything but organized.

Space entrepreneurs are excited about the promise of asteroid mining. But there are a lot of big, complicated questions they'll have to answer before we know if they can ever make a profit from it.

Asteroid mining is touted as the industry of the future. But how ready are we to harvest raw materials from the asteroid belt at a profit?

If you're worried about 2012, don't be. Now, 2036, that's another matter...
