Agnirva Space Premier League - Expedition #31385: Testing Tomorrow’s Materials in the Harshness of Space

The Materials International Space Station Experiment (MISSE) 1 and 2 provided a vital opportunity to study how advanced materials and coatings respond to the space environment. Placed on the exterior of the ISS during Expeditions 3 through 11, these passive experiments helped scientists select materials for future spacecraft, satellites, and even habitats on the Moon and Mars.

Led by Dr. William Kinard of NASA’s Langley Research Center, and supported by Boeing and the Marshall Space Flight Center, MISSE exposed over 1,000 material samples to atomic oxygen, vacuum, ultraviolet radiation, and extreme temperatures for up to four years.

The experiment tested polymers, paints, lubricants, solar cell materials, and sensors. Each sample was returned to Earth and meticulously examined for changes in physical, chemical, and mechanical properties.

One key finding was how atomic oxygen, prevalent in low-Earth orbit, erodes polymer surfaces—leading to improved protective coatings. MISSE also tested thin films for solar arrays and radiation shielding for electronics.

This pioneering work accelerated development for spacecraft that are lighter, more durable, and energy-efficient. Lessons learned continue to influence NASA’s Artemis program and commercial space missions.

MISSE 1 and 2 marked the beginning of a legacy in space materials research that continues today.
