The Indian Space Research Organisation (ISRO) has put out the first image of the illuminated moon surface. Taken by the Imaging Infrared Spectrometer (IIRS) payload, ISRO stated that it has commenced spectroscopic studies on the lunar surface.
ISRO posted the picture on Twitter and stated that the IIRS payload is “designed to measure reflected sunlight from the lunar surface in narrow and contiguous spectral channels.”
the intent of the payload and this assessment is to understand the origin and evolution of the moon. It will do so by scanning and then mapping the mineral composition of the moon’s surface. Using signatures in the reflected solar spectrum, the instrument will be able to discover the materials.

See the first illuminated image of the lunar surface acquired by #Chandrayaan2’s IIRS payload. IIRS is designed to measure reflected sunlight from the lunar surface in narrow and contiguous spectral channels.

The image shared is from the northern hemisphere that shows various carters including Sommerfield, Kirkwood and Stebbins. ISRO further stated that after a preliminary survey, it was proved that the IIRS was able to compute the variation in the reflected solar radiation that bounces off the moon’s surface for different kinds of surface types. Which includes central peaks on craters, crater floors and also the sun illuminated inner rims of craters.
After the Vikram lander’s fiasco, ISRO had put out images and the first scientific data from the Chandrayaan 2 mission, which is survived by the Orbiter. Captured by the Orbiter’s High Resolution Camera from an altitude 100km, ISRO said that the images are the highest resolution visuals ever taken of the Moon.
The Vikram lander and Pragyan rover, continue to be incommunicado with ISRO.
