Exploring the distribution and state of resources in the lunar polar regions has become a hotspot in the current international lunar exploration field. China's Chang'e-8 mission requires in-situ infrared spectroscopic exploration of the lunar polar regions. However, the extreme environmental conditions in these areas such as low illumination and low temperatures pose numerous technical challenges for infrared spectroscopic detection. Regarding the current state of technology for in-situ spectral detection on the lunar surface, this paper specifically analyzes the major technical challenges faced in polar region exploration, and discusses potential solutions, aiming to offer theoretical and technical support for in-situ spectroscopic exploration of the lunar polar regions.
