(08/07/1997) --- STS-85 Payload Specialist Bjarni V. Tryggvason gives a thumbs up as he is assisted with his ascent/reentry flight suit in the Operations and Checkout (O&C) Building. He is a Canadian Space Agency astronaut and was born in Iceland. Tryggvason has also been a flight instructor for the Canadian Air Force. Tryggvason is the principal investigator of the Microgravity Vibration Isolation Mount now flying on the Russian Mir space station. During STS-85, Tryggvason will conduct vibration isolation mount and fluid physics investigations. His work to study how Shuttle vibrations affect the results of experiments will be valuable to the International Space Station program, since this experiment is planned for use on that space platform. Tryggvason will also conduct Bioreactor experiments and assist Mission Specialist Stephen K. Robinson with photography
