SPACECRAFT

Mars Orbiter Mission Spacecraft:

Mars Orbiter Mission is India's first interplanetary mission to planet Mars with an orbiter craft designed to orbit Mars in an elliptical orbit. The Mission is primarily technological mission considering the critical mission operations and stringent requirements on propulsion and other bus systems of spacecraft. It has been configured to carry out observation of physical features of mars and carry out limited study of Martian atmosphere with following five payloads:

* Mars Colour Camera (MCC)
* Thermal Infrared Imaging Spectrometer (TIS)
* Methane Sensor for Mars (MSM)
* Mars Exospheric Neutral Composition       Analyser  (MENCA)
* Lyman Alpha Photometer (LAP)
