Leaner and Meaner: Materials Tested in Space Could Help Build More Space-Resilient Satellites

A close-up of a sample similar to those sent to the ISS to study their durability in harsh space conditions.

Researchers at the Georgia Tech Research Institute (GTRI) and Georgia Institute of Technology (Georgia Tech) are sending experimental polymer materials to the International Space Station (ISS) as part of the MISSE-22 mission to better understand how they withstand real space conditions.

Mounted outside the ISS and exposed to atomic oxygen, extreme temperatures, and radiation, the samples will later be returned to Earth for detailed analysis. The findings will help improve materials for future satellite constellations. The project brings together government, academic, and industry partners, including the Air Force Research Laboratory (AFRL), the University of Texas at El Paso (UTEP), California-based R&D firm Hedgefog Research Inc., DuPont de Nemours, and Aegis Aerospace.
