Terrain Mapping Camera (TMC – ISRO)
The Terrain Mapping Camera was a CMOS camera with 5 m resolution and a 40 km swath in the panchromatic band, used to produce a high-resolution map of the Moon. Its aim was to completely map the topography of the Moon. The camera works in the visible region of the electromagnetic spectrum and captures black-and-white stereo images.
When used in conjunction with data from the Lunar Laser Ranging Instrument (LLRI), TMC data also helped improve understanding of the lunar gravitational field.
TMC was built by ISRO's Space Applications Centre (SAC) at Ahmedabad. It was first tested on 29 October 2008 through commands issued from ISTRAC, capturing images of the Earth before Chandrayaan-1 left Earth orbit, and later returned some 70,000 lunar images including a full-Earth portrait.
