The orbiter's radar picks up colorful moon images of impact craters and illuminates the evolution of the moon India News



NEW DELHI: The synthetic aperture radar aboard the Chandrayaan 2 orbiter, orbiting 100 km above the lunar surface, has captured colorful images of impact craters that measure the age and origin of the craters in the Moon-South Pole area This, in turn, will help to understand the evolution of the moon.
Meanwhile, the US space agency Nasa has made it clear that its lunar orbiter Lunar Reconnaissance Orbiter has found no evidence of Vikram lander in the recent lunar images taken of its orbiter during a recent flyby.
The impact craters are circular depressions on the lunar surface caused by the constant shelling of meteorites, asteroids and comets. The synthetic aperture radar (SAR) L & S bands, a powerful remote sensing instrument for studying planetary surfaces and sub- strates, provide detailed information about impact crater morphology through its higher-resolution, wide-angle-of-field imaging capability.
In addition, the greater depth penetration force of the L-band (3-5 meters) helps to examine the buried terrain of the Moon to a greater depth. The L & S bands also help to identify and quantitatively estimate polar lunar icy water in permanent shaded areas.
The previous moon-bearing SAR with an S-band on the Chandrayaan-1
orbiter and the SAR on NASA-LRO had provided valuable data on the scattering characterization of ejecta materials (material derived from volcanic explosions) from impact craters.
Meanwhile, Nasa project scientist Noah Edward Petro said the LRO images of the South Pole area of ​​Chandrayaan-2 Vikram, which was targeted on October 14, contained no evidence of the lander.
Petro said that the camera crew carefully examined the images and used the change detection technique, but could not locate the lander that landed heavily on the moon in September.
