Posted by tourdemars to Mars Society at June 26, 2014 4:56 PMMars Society President Dr. Robert Zubrin has challenged Ad Astra President & CEO Dr. Franklin Chang Diaz to a debate at the 17th Annual International Mars Society Convention, which will be held in Ad Astra’s hometown of Houston, Texas August 7-10, 2014. The proposed debate proposition is: Resolved “Electric Propulsion in an Enabling Technology for Human Mars Exploration,” with Dr. Chang Diaz representing the affirmative side and Dr. Zubrin the negative side. Commenting on the challenge, Dr. Zubrin said, “This debate is critically necessary. Dr. Chang Diaz has been actively propagandizing an argument combining three claims. First, that cosmic radiation hazards dictate that current day propulsion, which enables six month transits from Earth to Mars, is too slow to enablehuman mission to Mars. Second, that therefore much faster forms of interplanetary propulsion are necessary before we dare undertake human Mars exploration missions. Third, that his VASIMR propulsion system would uniquely enable such quick trips.
