The design of an efficient Thermal Protection System (TPS) remains one of the most challenging tasks of planetary exploration missions. Because of the harshness of re-entry environments, no ground facility can exactly replicate all of these conditions. Consequently, engineers must rely on numerical models design TPS. To provide inexpensive flight validations for these model, the Kentucky Re-entry Universal Payload System (KRUPS) spacecraft has been developed at the University of Kentucky. As a technology maturation step, two KRUPS spacecraft were ejected from two separate sounding rockets at high altitudes. The capsules were instrumented so that the thermal behavior of the heat shield would be monitor during re-entry. For the first mission, KUDOS, a sub-scale capsule was launched on August 13th, 2017. KUDOS raised the Technology Readiness Level (TRL) from TRL 4 to TRL 5 by validating multiple sub-systems in a relevant environment. The second flight, KOREVET, was launched March 25th, 2018, and maintained the TRL 5 status, but the capsule was, this time, full-scale.
