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.



  • "IIRS is designed to measure reflected sunlight from the lunar surface in narrow and contiguous spectral channels," ISRO tweeted.
  • The lunar farside in the northern hemisphere is shown in the picture, along with the Sommerfield, Stebbins and Kirkwood craters.
  • 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.
  • Earlier, on October 4, ISRO had released a few snaps of the southern polar area of the Moon captured by the Orbiter High-Resolution Camera (OHRC) that are on-board Chandrayaan-2, of the
