Chandrayaan-2 orbits begin mapping Moon for minerals; Nasa craft takes more pictures to find Vikram | India News

NEW DELHI: A spectroscopic instrument aboard the Chandrayaan-2 orbital has taken the first illuminated image of the lunar surface with a goal of mapping the mineral and lunar composition. The data helps to understand the origin and evolution of the moon.
At one point, the orbiter's payloads are busy scanning the moon, NASA's orbiter LRO, present in the lunar orbit, has sent the latest images of the southern pole region where Isros Vikram landers had crashed and made every "rigorous" effort to find that lander's exact location.
The Orbiter & # 39; s Imaging Infrared Spectrometer (IIRS) has captured the first illuminated image that covers part of the moon's far side in the Northern Hemisphere. Few prominent craters like Sommerfield, Stebbins and Kirkwood can be seen in the picture. The IIRS is designed to measure reflected sunlight and emitted portion of moonlight from the lunar surface in various spectral bands ranging from 800 to 5,000 µm. It will also do complete characterization of water / hydroxyl.

Preliminary analysis of the data sent by orbits suggests that the IIRS was able to successfully measure variations in the reflected solar radiation bouncing off the lunar surface from various types of surfaces such as crater peaks, crater floors and sunlit inner rims of craters. The variations in the spectral radiation are mainly due to the mineralogical variations found in the lunar surface. More detailed analysis is expected to yield results on the heterogeneity of lunar surface compositions, Isro said.
Meanwhile, NASA's Lunar Reconnaissance Orbiter took a fresh set of images of the South Pole region on October 14 under better lighting conditions compared to the first set of images taken on September 17, when it was dusk on the moon and long shadows covered much of the terrain . NASA experts are still analyzing the images sent by LRO because the area captured is huge and makes "a rigorous search" to look for the Vikram lander, says LRO project researcher Noah Petro, an agency report said. He said that the LRO will fly over the South Pole region on November 10.
During the last descent on September 7, Vikram had crashed on the lunar surface and the Isro control room lost contact with the lander. An expert committee from Isro has investigated the causes of "communication loss" with the lander in the last moment and is likely to submit the probe report to PMO.
