thermally induced refraction in a micro-gravity atmosphere


THermally Induced Refraction in a Micro-gravity Atmosphere II is an optics experiment designed by University of Michigan Aerospace Engineering students. The purpose of THIRMA II is to test new technology for deep-space optics which could eventually lead to lightweight gas lenses instead of heavy mirrors in space telescopes.

In December 2002, THIRMA II was accepted in NASA's 2003 Reduced Gravity Student Flight Opportunities Program (RGSFOP). The RGSFOP allows selected undergraduate teams to fly micro-gravity experiments on board the KC-135A aircraft. The KC-135A, also known as the 'Vomit Comet', is used to train astronauts in zero-g and perform micro-gravity research.

THIRMA II flew on board the KC-135A in April 2003. Five team members transported the experiment to Houston and spent two weeks at Johnson Space Center for safety reviews, training and two successful flights. The team is now working on the data analysis and giving presentations for students of all ages in Southeastern Michigan. The THIRMA II final report will be available in August.

THIRMA II would not be possible without the generous support of many sponsors. The THIRMA II team would like to thank all those who have volunteered their time and supported the project in the past six months:

Professor Pete Washabaugh
Professor Luis Bernal
Tom Griffin, Technician
Chris Chartier, Technician
Dave McLean, Technician
Eric Kirk, Technician
Terry Larrow, Machinist
