The Indian Space Research Organisation (ISRO), released the first illuminated image of the moon’s surface captured by Chandrayaan-2’s Imaging Infrared Spectrometer (IIRS) payload, on Thursday.
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.
ISRO mentioned in a statement that the IIRS’ main role is to decipher the “origin and evolution of the Moon in a geologic context by mapping the lunar surface mineral and volatile composition using signatures in the reflected solar spectrum”.
IIRS can split reflected sunlight and disperses it into different spectral bands between 800 nanometer to 5000 nanometer, using a grating system.
