Mr. Vangen has worked extensively preparing experiments to fly aboard spacelab, a scientific research facility carried in the cargo bay of the space shuttle. He was responsible for integration and testing of experiments manifested on Spacelab-1, Spacelab-2, Spacelab-3, Astro-1, D-1, ATLAS-1, and TSS-1. As an experiment engineer he was responsible for preparing the payload elements for launch, including interface and functional testing, troubleshooting, repair, and support activities for launch and landing. He has also supported multiple space flight missions as a member of the experiment science teams for on-orbit operations at the Payload Operations Control Centers located at the Marshall Space Flight Center, Huntsville, Alabama, and the Johnson Space Center, Houston, Texas.
Until 1990, he was the lead electrical engineer for the Payload Checkout Unit, the major checkout system used for spacelab testing during experiment integration and checkout. His two most recent assignments, as the space station experiment integration lead electrical engineer and avionics lead, continued his involvement in payload operations as the Kennedy Space Center prepares for the next generation of space science technology, experiments, and payloads.
