Gamma Ray and Neutron Detector (GRaND)

The Gamma Ray and Neutron Detector (GRaND) is a scientific instrument designed to measure gamma rays and neutrons in space. It helps researchers study the composition of planetary bodies, such as asteroids and moons, by detecting high-energy radiation emitted from them. By analyzing this radiation, GRaND provides valuable insights into the materials that make up these celestial objects, helping us understand their history and evolution. The instrument was notably used on NASA's Dawn mission to study the asteroid belt and the dwarf planet Ceres, aiding our knowledge of the solar system.
