He was the originator and technical director during the early development phase of the Microgravity Vibration Isolation Subsystem (MVIS), which the CSA developed for the European Space Agency Fluid Science Laboratory for the ISS. On August 7, 1997, Mr. Tryggvason flew as a payload specialist aboard Space Shuttle Discovery on Mission STS-85. His primary role was to test MIM-2 and perform fluid science experiments designed to examine sensitivity to spacecraft vibrations, in order to develop a better understanding of the need for systems such as the MIM on the International Space Station (ISS), and to study the effect vibrations have on the many experiments performed on the ISS.</BLOCKQUOTE> So Tryggvason's main legacy seems to be vibration-isolation experiment mounts.
