Why should we care about asteroids?

According to Dr Timothy Holt, asteroids could present one of our best prospects for the future, if we can mine them for minerals or water.  How is this so?

Tim is an astronomer/planetary scientist and normally lives with his wife in Colorado USA.  However he is currently lecturing at the University of Southern Queensland and living in Ballarat with his parents, Speakers Club members Rick and Rita Holt.  So, we’ve nabbed him to speak to us before he moves on to his next assignment.

Tim will talk about the past, present and future prospects for our relationship with asteroids.
