This program is a special presentation by Drs. John Jurist, Sam Dinkin and myself at the University of North Dakota Department of Space Studies on April 12, 2005. This two hour presentation was in the form of a two hour interactive workshop with faculty and students both present for the workshop and on the internet as UND presented the program as a webcast to their alumni, distant learning students, and to the Space Show family of listeners. The audio only is archived on The Space Show website.
