"Adventures Fixing Spacecraft"

ABSTRACT -- Unexpected behaviors of materials have caused problems for spacecraft and instruments. One class of problems is the growth of needle-like filaments of metals (whiskers) that have caused short circuits that have killed many satellites and instruments. Another class involves the interactions of gold & indium, which have caused damage to the Geostationary Operational Environmental Satellite Program, IceSat I and IceSat II, and the Laser Communications Relay Demonstration (LCRD), among others.

SPEAKER -- Henning Leidecker is the Chief Failure Analyst of the Electrical Engineering Division at NASA's Goddard Space Flight Center. He received his PhD in Physics from The Catholic University of America, and then professed physics at The American University, and served as a member of the Technical Staff of Bell Telephone Labs. He has worked at GSFC since 1984. Awards include the NASA Agency Exceptional Service Medal; the NASA Agency Outstanding Leadership Award; the NASA Agency Exceptional Engineering Achievement Medal; the Silver Snoopy award; and the GSFC Moe I. Schneebaum Memorial Award for Engineering.
