India's Chandrayaan-2 takes colorful pictures of the impact craters of the Moon to study the evolution of the satellite.

Chandrayaan-2, currently orbiting the Moon, has returned colorful images with the impact craters that could help understand the evolution of the Earth's satellite. The images were taken on board with Chandrayaan-2's Dual-Frequency Synthetic Aperture Radar (DF-SAR) and give a closer look at the impact craters.

The moon has many impact craters on its surface that were created by meteorites. Asteroids and comets that have bombarded it since its creation. The pictures even come when NASA said in a statement that there were no signs of Vikram Lander. NASA's Lunar Reconnaissance Orbiter (LRO) failed to find any evidence for the Vikram Lander of the Indian Chandrayaan-2 during its flyby on October 14 over the Moon's South Pole region .

"The Lunar Reconnaissance Orbiter formed the area of ​​the destination landing place Chandrayaan-2 Vikram on October 14, however, has found no evidence of the Lander," said Noah Edward Petro, Project Scientist for the LRO mission, PTI in an e-mail. It used to be speculated that the Vikram Lander might be hiding in the shadow of the crater-filled region.

Impact craters are approximately circular depressions on the surface of the Moon, ranging from small bowl-shaped depressions to larger and complex multi-lingual impact collars. According to ISRO, the study of the type, size, distribution and composition of impact craters and the associated ejection characteristics will help to obtain valuable information on the origin and evolution of craters.

The images shared by Chandraayan-2 have been developed to obtain more detailed information about the morphology and ejecta of impact craters due to the higher resolution of the images. More importantly, the SAR for Chandraayan-2 uses the L & S band, which can provide more detailed information about the morphology and ejection material of impact craters. This allows for higher resolution images. The L-band has a greater depth penetration (3 to 5 meters), which allows to study the buried terrain at greater depths.

In a press statement, ISRO stated that Synthetic Aperture Radar (SAR) is a more powerful remote sensing instrument for studying planetary surfaces and subsoil because the radar signal can penetrate the surface. The SAR is also sensitive to roughness, structure and composition of the surface material and the buried ground.
