Ok ok that should be craters not carters. My spell checker did not catch that. Another advantage of this mission is that a radio radio telescope could be set up free from the radio interference from earth. Other telescopes could be deployed that can study the heavens from earth's atmosphere. I agree with what was said about a manned mars mission. Robotic probes are way more cost effective and can go way more places. Sincerely, Gary Vardon The book DO It Right will help you understand vital ideas leading to your greater success.
