Should we or could we ‘Nuke’ #Mars? #NukeMars (Video)

In our latest video, Dr. Jim Daly of Astronomy for Change discusses the recent interest in colonizing Mars through ‘Terraforming’. Elon Musk is pushing the idea of rapidly warming the surface of the Red Planet using clean Nuclear Fusion ‘bombs’ and thus rapidly increasing the planet’s average surface temperature. Through a thoughtful choice of the[…]
