Parker solar probe structural-thermal analysis challenges
The NASA Parker Solar Probe spacecraft, built by the Johns Hopkins University Applied Physics Lab will fly through the outermost part of the Sun s atmosphere taking in situ measurements and imaging to improve our understanding of the corona and the solar wind. The Thermal Protection System (TPS), a 4.5-inch thick carbon-composite heat shield, limits heat transfer to the spacecraft during its flight through the Sun s atmosphere, and casts a shadow which protects the spacecraft and its instruments from the harsh thermal enviro ...

Protecting flight hardware during spacecraft vibration testing through greater understanding of the CONTRL systems ability to control input and limit responses
Spacecraft level vibration testing exposes the as-built spacecraft, in its flight configuration, to the low frequency (<100 Hz) dynamic environment experienced during launch with the primary objective of verifying structural integrity and system performance. This test requires as flight-like of a configuration as possible and is therefore typically one of the last tests performed in the spacecraft verification program. At this level of integration (spacecraft), failures pose a much greater risk to the program than at lower l ...
