As of my last update in September 2021, the most detailed image of the moon was captured by NASA's Lunar Reconnaissance Orbiter (LRO) spacecraft. The image, known as the Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC) mosaic, is composed of thousands of individual photographs taken over a period of several years. It has a resolution of 100 meters per pixel and provides a comprehensive and detailed view of the lunar surface.

The LROC WAC mosaic covers almost the entire lunar surface and reveals features as small as 100 meters in size. It showcases the moon's topography, craters, mountains, valleys, and other geological formations with unprecedented clarity. The image also highlights variations in the lunar surface, including the presence of different minerals, rocks, and surface features.

This high-resolution image is particularly valuable for scientific research and enables scientists to study the moon's surface in greater detail. It aids in understanding the moon's geological history, composition, and processes that have shaped its surface over time.

While the LROC WAC mosaic remains the most detailed image of the moon captured by a spacecraft, it's possible that more recent missions or advancements in imaging technology may have captured even more detailed pictures of the moon. To obtain the most current and up-to-date information on lunar images, I recommend consulting reputable space agencies or scientific publications that specialize in lunar research and exploration.
