Chandrayaan2: latest updates
November 13, 2019 Terrain Mapping Camera-2 (TMC-2) is a follow-on of the TMC on-board Chandrayaan-1. TMC-2 provides images (0.4μm to 0.85μm) at 5m spatial resolution & stereo triplets (fore, nadir and aft views) from a 100 km orbit for preparing Digital Elevation model (DEM) of the complete lunar surface. The triplet images from TMC-2 when processed into Digital Elevation Models, enable mapping of surface landform morphologies. These include Craters (formed by impactors) Lava tubes (potential sites for future habitability) Rilles (furrows formed by lava channels or collapsed lava tubes) Dorsa or wrinkle ridges (formed mostly in Mare regions depicting cooling of and contraction of basaltic lava) Graben structures (depicts the structural dislocations on the lunar surface ) Lunar Domes/ Cones (denoting localized vents of past volcanism on the Moon). The derived information facilitates estimation of dimensions of above features and its comparison for reconstructing t
