An instrument called the Lunar Atmospheric Composition Experiment (LACE) deployed on the surface of the moon during the Apollo 17 mission has given some clues about the moon’s atmosphere composition. This instrument detected small amounts of a large number of atoms and molecules. Moon’s atmosphere is largely made of helium, neon, argon, and hydrogen. Helium, neon, and argon are chemically inert gases that do not react with other elements under normal circumstances. However, hydrogen is highly reactive. The lunar atmosphere is also composed of small amounts of various molecules such as ammonia, methane, potassium, sodium, and carbon dioxide.
