The Chang’e 6 landing site is situated toward the southern edge of the Apollo basin (about 306 miles or 492 km in diameter, centered at 36.1 degrees south latitude, 208.3 degrees east longitude). Basaltic lava erupted south of Chaffee S crater about 3.1 billion years ago and flowed downhill to the west until it encountered a local topographic high, likely related to a fault. Several wrinkle ridges in this region have deformed and raised the mare surface. The landing site sits about halfway between two of these prominent ridges. This basaltic flow also overlaps a slightly older flow (about 3.3 billion years old), visible further west, but the younger flow is distinct because it has higher iron oxide and titanium dioxide abundances.
NASA’s Lunar Reconnaissance Orbiter (LRO) is a pivotal spacecraft designed for detailed exploration of the Moon’s surface. Launched on June 18, 2009, the mission primarily aims to gather high-resolution imagery and data to facilitate the selection of future landing sites, assess the Moon’s mineral resources, and analyze the lunar radiation environment. Equipped with a suite of powerful instruments, including high-resolution cameras and a laser altimeter, the LRO maps the lunar terrain in exceptional detail, helping scientists understand the Moon’s geology and identify areas rich in resources like water ice.
The LRO has significantly advanced our knowledge of the Moon, contributing to discoveries such as confirming the presence of water ice in permanently shadowed craters and mapping lunar surface temperatures. Instruments like the Lunar Orbiter Laser Altimeter (LOLA) and the Diviner Lunar Radiometer Experiment provide critical data on lunar topography and thermal behavior, crucial for planning future human and robotic missions. By continuing to transmit valuable data back to Earth, the LRO supports ongoing research that enhances our strategies for returning to the Moon and beyond, marking it as a cornerstone of lunar exploration technology.
