Isro released the lunar surface images captured by the Terrain Mapping Camera 2 (TMC-2) on August 23 from an altitude of 4,375km. One set of images show impact craters such as Jackson, Mitra, Mach and Korolev. Jackson is an impact crater located in the northern hemisphere of the far side of Moon. It is a 71km diametre crater at 22.4°North, and 163.1°West (shown in inset).
- The interesting feature at the western outer rim of Mach crater is another impact crater and Mitra (92 km diametre) crater named after Prof Sisir Kumar Mitra, who was an Indian physicist and Padma Bhushan recipient known for his pioneering work in the field of ionosphere and Radiophysics.
- The Korolev crater seen in the image is a 437 km crater which has several small craters of varying sizes.
- The TMC also captured impact craters Sommerfeld and Kirkwood. Sommerfeld is a large impact crater located in the farside northern latitudes of the Moon. It is a 169km diametre crater at 65.2°North and 162.4°West.
- Sommerfeld has a relatively flat interior surrounded by a ring mountain and a number of smaller craters lie along the rim edge. The crater is named after Arnold Sommerfeld who is a German physicist pioneered in the field of atomic and quantum physics.
- North east to this crater lies the Kirkwood crater named after the American astronomer Daniel Kirkwood, another well-formed impact crater which is approximately 68 km diametre.
- Besides, the TMC also imaged the lunar north polar region imaged to capture craters such as Plaskett (109km), Rozhdestvenskiy (177km) and Hermite (104 km).
- Rozhdestvenskiy is one of the coldest spots in the solar system with temperature dipping to nearly -300 Degree Celsius.
