Spectroscopic techniques have played a role in advancing space exploration applications, including the exploration of Mars. By measuring how matter interacts with electromagnetic radiation, spectroscopy provides key insights into the chemical makeup of planets, stars, and interstellar materials (2). Some of the common spectroscopic techniques used in studying space include infrared (IR), ultraviolet (UV), Raman, and mass spectrometry (MS).
