Marshall Martin provided this month's Deep Space Message. Here is the text of his message: To Whom It May Concern: By the time you receive this message, my planet Earth maybe gone and all my descendants too. Many think it will be by war or global warming. I know there are bigger problems looming like: A major asteroid impact, loss of our radiation blocking magnetic field, and or a stellar dust cloud blocking our sun's warming rays. If this happens, know that our species constantly fought with each other over power and prestige.

Leonard David returned to The Space Show for this program. Leonard talked about his work at space.com, current articles and future research for articles that he is presently doing. He provided his thoughts on the shuttle, the vision program, Mars, NASA and the public interest in space, and lots more. We spoke about energy from space, global warming, the private-sector and space launch, including space tourism. As the senior writer at space.com, Leonard David took us through the subjects and topics that drive and make the space program today, both public and private.
