The lunar atmosphere is a very thin layer of gases surrounding the Moon. Despite being extremely sparse compared to Earth's atmosphere, the lunar atmosphere plays a key role in influencing the surface conditions on the Moon. It is primarily composed of helium, neon, hydrogen, argon, and trace amounts of other elements. Research on the lunar atmosphere aims to understand its composition, dynamics, and how it interacts with the lunar surface. Scientists are interested in studying how the lunar atmosphere evolves over time, and how it responds to changes in solar activity. This research is important for understanding the lunar environment and its potential impact on future human missions to the Moon.
