NASA Demonstrates Next-Generation Heat Shield Technologies

NASA is testing heat shields that can keep astronauts safe as they return from missions to the Moon and Mars in an unusual way: by taking out the trash.
When Northrop Grumman 24 th cargo resupply mission for NASA undocked from the International Space Station, it carried a fleet of 12 small, experimental capsules designed to test the next generation of thermal protection materials that could serve as the foundation for future heat shields.
