Aitken Central Peak, Seen Obliquely

December 5, 2012
Occasionally LRO is commanded to look off to the side at extreme angles to snap spectacular views. On 11 January, 2011 (hot off the press!) LROC shuttered this spectacular of Aitken crater. Here LROC was looking over the southwest ridge of its central peak. In the distance the lower portion of the northeastern walls of Aitken crater itself is just visible. The Lunar Reconnaissance Orbiter has collected an extremely limited number of these oblique views of the lunar surface, which are useful for engineering purposes and visualizing key geologic features on the lunar surface -- like Aitken. Aitken (~135 km in diameter) is one of the most geologically diverse settings on the farside. The crater is mapped as an Imbrian-aged feature, and its floor is covered in a small puddle of mare basalt; mare deposits are quite rare on the lunar farside, and lunar scientists are still trying to figure out why. Aitken is also on the northern rim of the great South Pole-Aitken basin, the oldest and largest impact basin on the Moon and one of the oldest and largest impact basins in the whole Solar System! Further exploration of the South Pole-Aitken basin is one of the highest priorities for planetary science in the next decade. LROC WAC mosaic of the central portion of Aitken crater.
