I've lived in several states but grew up mostly in California and Tennessee. I attended the University of Tennessee for an Aerospace Engineering degree and worked at NASA's Marshall Space Flight Center for 26 years; I left NASA in 2005. I now live near Huntsville Alabama where I spend my time riding my bike(s), hiking, programming computer graphics, traveling and reading. Mark preparing for the Galibier
