The NASA is currently testing next-generation thermal shields designed to protect astronauts returning from lunar or Martian missions. This experiment, called the Kentucky Reentry Probe Experiment (KREPE-3), uses 12 small experimental capsules aboard Northrop Grumman’s Cygnus XL 24 resupply mission, which departed the International Space Station on October 7.
These capsules, designed by students from the University of Kentucky, are equipped with sensors measuring temperature, pressure, motion, magnetic field, and light during atmospheric reentry. As the cargo disintegrates in Earth’s atmosphere, it releases these capsules, which transmit live data via satellite to researchers.
This innovative method allows the collection of valuable information on thermal protection materials under real conditions while utilizing an end-of-life vehicle. The project is a collaboration among NASA, the University of Kentucky, the State of Kentucky, NASA’s EPSCoR program, several NASA centers, and federal and commercial partners.
According to David Berger, head of NASA’s EPSCoR program, this initiative supports training future scientists and engineers while contributing to NASA’s objectives. Keith Peterson, a materials engineer at NASA’s Ames Research Center, emphasizes that this approach enables flight data acquisition on materials still in development by leveraging a vehicle already returning to Earth.
