NASA’s THEMIS program was developed to discover answers to questions about factors that influence the operation of other space satellites, ground power grids, communications, and other factors affecting our lives here on Earth.
When NASA commenced the mission in March 2003, it selected Swales Aerospace to build the Probe Bus and Carrier. Swales, who has been providing services for study, design, development, fabrication, integration, testing, verification, and operation of space flight as well as ground system hardware and software since 1978, turned to MSC. Software to expedite the development and validation processes involved in the THEMIS project.
“MSC. Software modeling tools were used extensively to validate the Probe Bus deployment clearances analysis,” said Michael Cully, THEMIS program manager for Swales Aerospace. “These tools were a critical element in solving a difficult problem. They served as the only means of validating that the design met all critical clearance requirements, as a system deployment test of all the Probes on the Probe carrier was not possible.”
The launch marked the first ever simultaneous deployment of five NASA satellites from a single launch vehicle.
