Earth's space environment is crucial for space activities and technology. Continuous monitoring and research are vital. Traditional methods rely on ground−based observatories and satellites with limitations. Lunar exploration advances have made Moon−based remote sensing of Earth's space environment an emerging approach. This paper reviews relevant research progress, including lunar observation platforms, remote−sensing tech, applications, challenges, and future directions. Moon−based observation offers long−term continuity, global coverage, a unique perspective, and a stable platform. It has great potential in space weather monitoring, Earth space environment change research, and planetary science comparisons. As lunar exploration tech develops, Moon−based remote sensing will increasingly contribute to understanding Earth's space environment, ensuring space activity safety, and exploring cosmic mysteries.
