APOD: 2026 October 10 – Lunar Farside - NASA Science

Summary: This Astronomy Picture of the Day features a detailed mosaic of the Moon's farside, captured by the Lunar Reconnaissance Orbiter (LRO).

This image is a global mosaic of the Moon's farside, compiled from over 15,000 images taken by the Lunar Reconnaissance Orbiter's wide-angle camera between November 2009 and February 2011. Unlike the nearside, which is characterized by smooth, dark lunar maria, the farside is notably rugged and heavily cratered. Astronomers attribute this difference to a thicker crust on the farside, which inhibited the flow of molten material from the interior to the surface.
