2000 - STS -92 Discovery    Launched at  6:17 p.m. CDT, ISS mission 3A included the installation of the Integrated Truss Structure (ITS) Z1, Pressurized Mating Adapter 3 (PMA 3), Ku-band Communications System, Control Moment Gyros (CMGs)

1992Steven G. MacLean (Ph.D.) launches on STS-52 (Columbia). Born in Ottawa, Ontario he served as Payload Specialist. .He earned a bachelor of science degree in honors physics and a doctorate degree in physics from York University. He was a member of Canadian National Gymnastics Team 1. Dr. MacLean is a laser physicist whose research has included work on electro-optics, laser-induced florescence of particles and crystals, and multiphoton laser spectroscopy.  He was one of six Canadian astronauts selected in 1983.  A series of seven Canadian experiments operated by Steve investigated material science, fluid physics, atmosphere characterization, and the human body's ability to adapt to space flight. Steve is astronaut adviser to the Strategic Technologies in the Automation & Robotics Program, and program manager of the Advanced Space Vision System. STS-52 completed 159 orbits. Mission duration: 9 days 20 hours and 56 minutes.

It is my conclusion that human evolution and the motions of matter in space are intrinsically linked. The observation and understanding of the complexity of biological history on Earth cannot be complete without the tandem observation and understanding of a dynamic greater cosmos. - SpaceGene
