These materials are being tortured in space
High-energy radiation and atomic oxygen wreak havoc on satellite parts. To evaluate the durability of materials being developed for future satellites, the U.S. Naval Research Laboratory is running samples through a space-based torture test called MISSE-8. Astronauts bolted a platform full of one-inch samples of mirror coatings, laser-tuning crystals, structural foam and other materials to…
