Dr. Matthew Tiscareno tells us about Saturn's rings. He describes how scientists measured their mass, and how the rings got their colors. He also explains why scientists are currently debating the age of the rings.
Professor Desireé Cotto Figueroa tells us about her research into the strength of meteorites. This research helps scientists understand the hazards from asteroids, and also will help engineers design asteroid-visiting spacecraft.
