Student-built capsules survive intense re-entry heat in NASA experiment

In July 2024, five student-built capsules successfully survived re-entry through Earth's atmosphere during the Kentucky Re-Entry Probe Experiment (KREPE-2). This mission tested various heat shield prototypes under real conditions, providing valuable data for future spacecraft design. The capsules, developed by University of Kentucky students, with NASA funding, endured temperatures exceeding 4,000 degrees Fahrenheit. They transmitted critical flight data via satellite, which is now being analyzed to enhance thermal protection systems for crewed and uncrewed missions. KREPE-2 builds on the earlier KREPE-1 mission from December 2022, which focused on basic temperature measurements. The upcoming KREPE-3 is planned for 2026, continuing the student-led initiative in spaceflight technology.
