was a commentator on Australian Broadcasting Corporation and BBC on 18 Nov 2010. He appeared on several popular science and call-in shows in each Australian state, Australia-wide and on BBC. The combined audiences were more than one million listeners. The largest were the Mornings with Zan show
on Australian Triple J radio and Radio Five Live on BBC
. Doc Finkleman spoke about his role at Cheyenne Mountain on 9/11, space situational awareness and the crusade to save the leap second. Since there are few satellite tracking and space surveillance capabilities in the Southern Hemisphere, Australia is pivotal in monitoring space activity and preserving the space environment. Doc was invited to Australia by Dr. Karl Kruszelnicki, a popular science commentator, and Julius Sumner Miller, a physics professor at the University of Sydney. By coincidence, Doc and Professor Miller taught at the USAF Academy at the same time in the late 60s and early 70s. Karl and Doc fielded questions on many facets of space activity. One of the most interesting was why Mars, with an atmosphere of mostly CO2, doesn't have a global warming problem. The answer is that Mars is much farther from the Sun, so its surface is still pretty cold. Despite absorbing the Sun’s radiation, Mars reradiates in spectra that are not absorbed by CO2.
