Mars Colour Camera (MCC) on-board Mars Orbiter Mission is considered the ‘eye’ of the mission, taking photographs (imageries) of the surfacial features on Mars, and the cloud and dust around it. MCC is an important contextual camera for other non-imaging sensors like MSM, TIS, LAP, etc. The camera has been designed, characterized, calibrated and qualified at the Space Applications Centre, ISRO, Ahmedabad by a team of professional engineers and scientists. It has been miniaturized, ruggedized and space-qualified to match the weight and power budget of the mission. During Earth orbit phase, the images returned by the camera have been analysed qualitatively and quantitatively. The results show that MCC has been working as expected in terms of radiometry, geometry and application potential to discern various morphological features. The present article discusses these facts in detail.Keywords

Gravity highs surrounding Bundelkhand Craton and three sets of sub parallel paired aeromagnetic anomalies along its SE margin are attributed to High-Density, high susceptibility volcano sedimentary sequences and mafic intrusives of Bijawar Group of rocks of Paleo-Proterozoic period. Modelling of airborne magnetic anomahes provide almost vertical intrusives of high susceptibility (1 x 10-3emu) mafic rocks at a depth of about 850m below northern margin of Vindhyan sediments in the basement which is supported from high velocity rocks at the same depth in an adjoining seismic section. Both these anomalies are typical of those observed along rifted continental shelves world over as in case of western margin off India, Norway, Red Sea Rift, etc.Gravity highs and linear magnetic anomalies along southern margin of the Vindhyan basin are attributed to mafic and ultramafic intrusives of older Mahakoshal group of rocks with volcano sedimentary sequences of sectoral nature at the rifted margin of Bundelkhand craton similar to canyon deposits along present day continental rise and slope. The undisturbed Vindhyan sediments of Meso-Neo-Proterozoic period were deposited on the platform provided by continental shelf of Bundelkhand craton during convergence as fore land basin. This is in conformity with relative ages of Mahakoshals, Bijawars and Vindhyan sediments as they formed during rifting and convergence phases, respectively. Volcanic plugs (~1.11 Ga) associated with northern margin of Vindhyan basin (Panna diamond belt) and Mahakoshal Group of rocks (Jungel pipes) towards the south lying with in zones of high magnetic anomahes (mafic/ultramafic rocks referred to above) might be related to the same rifting process, but extruded to surface at later dates. Gravity high east of Aravalli Delhi Mobile Belt forming the Agra-Shahjahnpur ridge bounded by northward extensions of Great Boundary Fault and Chambal fault, is attributed to rocks equivalent to Mahakoshal Group of rocks along the western margin of the Vindhyan basin extending under the Ganga basin up to the Himalayan front in Western Nepal where seismically active zone of Western Himalaya starts.

The paper presents the design and development of Terrain Mapping Camera-2 (TMC-2) for Chandrayaan- 2 including science objectives; system and sub-system configuration along with the realized performance of the camera; payload characterization; aspects related to data products, etc. TMC-2, onboard Chandrayaan-2 orbiter-craft is a follow-on of the Terrain Mapping Camera (TMC) onboard Chandrayaan- 1. It operates in visible panchromatic band. It comprises three identical electro-optical chains aligned for three views (–25, 0 and +25 degree) along track direction for generation of stereo images. It provides data with 5 m horizontal ground sampling distance to generate digital elevation model. TMC-2 based on the new configuration and sub-system designs has reduction in mass and power by more than 40% compared to TMC, without compromising the performance.Keywords
