Theme 3: Protecting Our Explorers

Space is a dangerous place. Cosmic radiation, long confinement, limited resources, and weak gravity all pose serious risks to off-planet travelers. One of the trickiest hazards comes from a surprising source: dust. 

 Tiny particles can cause big problems. Lunar dust sticks to almost everything, increases spacesuit wear and tear, and, when tracked into a spacecraft, makes the air harder to breathe. As space missions grow longer, it will become even more important to understand how substances like Moon dust affect human lung tissue. RISE2 scientists use simulated Moon materials to perform tests that will help answer this question.  

The RISE2 team develops innovative ways to create samples and mimic space weathering processes, making simulated extraterrestrial materials as true-to-life as possible. Scientists use these samples in tests for DNA damage, cell death, and other problems in cell cultures and whole animals (e.g., mice).
