The time to start planning the next large international space mission is now. That mission should be a human mission to Mars. Despite the troubling economic and budgetary times, there is clear support in the U.S. for human Mars exploration.

The argument goes, "We've done such a crappy job of caring for our planet that we really do need to look for another place to live." I suppose that's what bugs me about Mr. Hawking's call for more public money for space exploration. It's the rationale.
