Secondary Craters around Orientale basin as observed from Chandrayaan-2
The very first image acquired recently from India’s Chandrayaan-2 mission has captured the SE portion of the far side of the Moon, showing highly cratered high land region with two dark mare patches belonging to Orientale and Apollo basins. In the upper portion of the image, the lower half of Orientale basin, one of the largest (~930 km diameter) and youngest (~3.8Ga) impact basin on the Moon could be observed. Apollo crater is another prominent feature as observed towards the eastern side of the image as characterized by double-ringed structure. Many degraded small and big impact craters and a few fresh craters are also present. Besides these, the region is showing population of small craters distributed radially from the Orientale basin in form of continuous trails formed by secondary impact cratering process.
