Indian Space Research Organisation(ISRO) today released the first illuminated image of surface of moon taken by Imaging Infrared Spectrometer (IIRS) payload on-board Chandrayaan-2.
The space agency tweeted and shared the image on its account, 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.
The first illuminated image of the lunar surface was acquired by IIRS. The image covers part of the lunar farside in the northern hemisphere. Few prominent craters are seen in the image (Sommerfield, Stebbins and Kirkwood).
The Imaging Infrared Spectrometer (IIRS) on-board Chandrayaan-2 is designed to measure the reflected sunlight and emitted part of Moon light from the lunar surface in narrow and contiguous spectral channels (bands) ranging from ~800 – 5000 nanometer (0.8-5.0 micrometer (µm)). It uses a grating to split and disperse the reflected sunlight (and emitted component) into different spectral bands.
The major objective of IIRS is to understand 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.
Earlier, the agency had also released images of the moon clicked by Orbiter High Resolution Camera (OHRC) onboard Chandrayaan-2.
ISRO lost contact from its Lander Vikram which was supposed to soft-land on the far side of the moon on 7th September. Minutes before its scheduled soft-landing, the communication with Vikram Lander was lost.
The Vikram Lander successfully separated from Chandrayaan-2 Orbiter on September 2. After revolving around the earth's orbit for nearly 23 days, the craft began its journey to the moon on August 14. The mission took off from the Satish Dhawan Space Centre in Sriharikota on July 22.
