ISRO shared the image on Twitter and said that the IIRS payload is "designed to measure reflected sunlight from the lunar surface in narrow and contiguous spectral channels".

Part of the lunar farside in the northern hemisphere can be seen in the image tweeted out by ISRO.

Chandrayaan-2 on Thursday beamed back the first illuminated image of the lunar surface acquired by Imaging Infrared Spectrometer (IIRS) payload.

The image contained a graph indicating the region of reflected and thermal emission component, and the spectral region of the reflected solar radiation.

ISRO captioned the image as 'Preliminary analysis of Chandrayaan-2 Imaging Infrared Spectrometer (IIRS) data and pointed out to several craters on the lunar surface.

Isro had earlier released the pictures of the Boguslawsky E Crater - measuring about 14 km in diameter and 3 km depth - and its surroundings in the southern polar region of the moon, clicked by the Orbiter High Resolution Camera (OHRC), mounted on the Chandrayaan-2 Orbiter.

On August 20, Chandrayaan-2 entered the orbit of the Moon after which it again went through a series of five lunar orbit manoeuvres.

NASA on September 27 released pictures of the landing site of Chandrayaan 2.

The image also underlines some of the prominent craters or bowl-shaped depressions present including Sommerfield, Stebbins and Kirkwood. It is meant to measure the reflected sunlight and emitted part of Moonlight from the lunar surface.

More detailed analysis that will follow is expected to yield important results on the heterogeneity of the composition of the lunar surface. The mission took off from the Satish Dhawan Space Centre in Sriharikota on July 22.

In a statement to national broadcaster Doordarshan, ISRO chief K Sivan had blamed faulty execution of the last stage of the operation for the loss of communication.
