India Chandrayan-2 makes color images of the moon's impact craters that could help study the evolution of the satellite.

Chandrayan-2, which is currently orbiting the moon, sent back color images showing impact craters that could help in further understanding the evolution of the Earth's satellite. The images were taken by Chandrayaan-2's dual-frequency radar synthesizer (DF-SAR) on board and give a more detailed look at impact craters.

The moon has many impact craters on its surface, formed by meteorites, asteroids, and comets that have bombarded it since its inception. The images come even after NASA in a statement said there was no sign of Lander Vikram. The NASA Lunar Orbit (LRO), in its flight on October 14 over the Moon's Polar Moon Area, failed to find any evidence of Vikram's port at Chandrayan-2 .

"The image of the Lunar reconnaissance zone at the Chandrayaan-2 Vikram landing site on October 14, but did not observe any evidence of landing," says Noah Edward Petro, LRO mission scientist, PTI in email. Earlier speculation was that Vikram's land could be hidden in the shadows in a crater-filled area.

Impact craters are roughly circular depressions on the surface of the moon, ranging from small bowl-shaped depressions to larger and more complex ring-shaped impact pools. According to ISRO, an examination of the nature, size, distribution and composition of impact craters and associated discharge characteristics will help to reveal valuable information about the origin and evolution of the craters.

The images shared by Chandraayan-2 are designed to produce more detailed details about the morphology and material of the impact craters as the images are with higher resolution. More importantly, the Chandraayan-2 SAR uses the L&S tape, which can produce more detail about the morphology and materials of the impact craters. This allows for higher resolution images. The L strip has a greater depth of penetration (3-5 meters), which allows exploration of the buried terrain at greater depths.

In a press release, ISRO explained that Synthetic Aperture Radar (SAR) is a more powerful remote sensing tool for studying planetary surfaces and subsurface because radar signal can penetrate the surface. SAR is also sensitive to roughness, structure and composition of surface material and buried terrain.
