Summary
| Description |
English: "GRS measures gamma rays emitted by the nuclei of atoms on Mercury’s surface that are struck by cosmic rays. Each element has a signature emission, and the instrument will look for geologically important elements such as hydrogen, magnesium, silicon, oxygen, iron, titanium, sodium, and calcium. It may also detect naturally radioactive elements such as potassium, thorium, and uranium. " |
