Bengaluru, October 17: The Indian Space Research Organisation on Wednesday released the first illuminated image of the lunar surface acquired by Chandrayaan 2’s Imaging Infrared Spectrometer (IIRS) payload. ISRO informed that show the far-side of the moon in the northern hemisphere, where few prominent craters can be seen in the image.

According to ISRO, IIRS is part of the spectrometer which is on-board Chandrayaan-2, whose work is to measure the reflected sunlight and emitted part of Moonlight from the lunar surface in narrow and contiguous spectral channels (bands) ranging from ~800 – 5000 nanometer (0.8-5.0 micrometre (µm)). The IIRS uses grating to split and disperse the reflected sunlight into different spectral bands, states TOI report.

Adding more, ISRO had stated earlier the major objective of IIRS is to understand the evolution and origin of the earth only natural satellite in the geological context. The IIRS maps teh moon's surface minerals and its composition by using signatures in the reflected solar spectrum. Chandrayaan 2 Update: NASA Lunar Orbiter to Fly Over Vikram Lander Lying on Moon Surface, Likely to Send Pictures.

It is to be known that ISRO launched Chandrayaan 2 on June 22. Though ISRO had planned the soft landing of Vikram lander on the lunar surface on September 7, it was partially damaged, and connection could not be established.
