astroengine writes "It’s 40 years to the day that the final mission to the moon launched. Discovery News speaks with Apollo 17 astronaut and geologist Harrison "Jack" Schmitt about where he thinks the Earth’s only satellite came from and why he thinks a NASA manned asteroid mission is a mistake. "I think an asteroid is a diversion," said Schmitt. "If the ultimate goal is to get to Mars, you have a satellite only three days away that has a great deal of science as well as resources. The science of the moon has just been scratched. We’ve hardly explored the moon.""
