Mars Orbitor Misson (MOM) is the spacecraft launched by Indian Space Research Organization on 5th November from Sri Harikota.  It is also called Mangalyaan.

It has entered the planned orbit around Mars on 24th September, 2014.  The prime minister and several dignitaries watched the launch in person at Sri Harikota. The whole of the nation watched it on the live telecast.

  MOM has raised Indian Space Program to a higher level. ISRO launched with success in the first attempt itself. Other countries could not achieve that. Mangalyaan is the first inter-planetary mission for India. Its project cost was Rs 450 crores.

  The main objective of MOM is to demonstrate our capabilities and status in space technology. The MOM will explore the minerals, morphology, surface features and atmosphere using indigenously developed equipment and instruments.

  In the payload of 15kg, MOM carries five scientific instruments. A photometer measures the availability of Hydrogen and Deuterium. Their ratio tells us about the amount of water lost to the outer space. Methane sensor will measure the amount of methane in the atmosphere.   A composition analyser senses and analyses the neutral composition of the atmosphere. A color camera sends us the photographs of the surface and the surroundings.
MOM revolves in an elliptical orbit around Mars with a time period of nearly 73hours. The mission is expected to function for six months.
