New Delhi, Oct. 18 -- One of the spectrometers (an instrument that measures wavelengths to tell the properties of an object) on-board the Chandrayaan-2 orbiter has captured its first illuminated image.

The image, released by the Indian Space Research Organisation (Isro), captures part of far side (the part of the moon facing away from the Earth) in the northern hemisphere of the moon.
