Professor Kathy Campbell was invited to talk with Alison Mau on the Paul Henry Show about the impact on humanity of the Moon landing 47 years ago, and to discuss Peter Schultz’s latest paper on the origins of the Moon as we know it.

Here is the link to the live show:

Science Media Centre says it well: “The Moon’s groovy origins: A baby planet broke apart around 4.1 to 3.7 billion years ago and sent a hunk of rock about 250 kilometres wide crashing majestically into the Moon, building up grooves around a 1,250 kilometre-diameter crater, say US astrophysicists. This baby planet, called a proto-planet, would have broken away from the asteroid belt and tumbled through our solar system until it found a nice hefty gravity to give a big explosive kiss to, the authors explain. They add that the findings give insight into the size of asteroids that gave the near side of the moon its pockmarked appearance”
