MARS ORBITER MISSION

BASICS	·         The Mars Orbiter Mission (MOM)(official name), informally called Mangalyaan . ·         Launched using  using a Polar Satellite Launch Vehicle (PSLV) rocket C25. ·         It is India's first interplanetary mission and, if successful, ISRO would become the fourth space agency to reach Mars, after the Soviet space program, NASA, and the European Space Agency. ·         MOM will follow MAVEN on Mars. NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft launched in same year.
OBJECTIVES	·         The ISRO built orbiter carries five instruments to detect methane on Mars, to study its geological activity, to study the Martian atmosphere  ·         Exploration of Mars surface features, morphology, mineralogy and Martian atmosphere by indigenous        scientific instruments.  ·         The MOM will also study the atmosphere of Mars, using a methane gas sniffer. On Earth, methane can have both geological and biological origins, so detecting it on Mars could suggest the presence of Martian microbes, ·         look at Mars' mineralogy, morphology and surface features.
STATUS	·         ISRO used in Mars spacecraft's , propulsion system, called 440 Newton engineor. ·         ISRO now have entered the spacecraft into the mars orbit. ·          It is one of the cost effective interplanetary mission $74 million 1/3rd cost of MAVEN. ·         Scientific objective was empirical observation of the planet. Periapsis (427km) nearest point in orbit of mars Apoapsis (76,993km) is farthest point. ·         Orbiting around mass at an angle of about 150 degree of mars equator.
MISSION ORBIT PHASE	1.       Geo Centric Phase-In this phase the spacecraft is projected to escape earth sphere of influence which is about 9, 18,000km.   2.       Helio Centric Phase – In this stage the space craft leaves the earth orbit. It travels tangentially to earth’s orbit and intersect tangentially the mars orbit.   3.       Martian phase- In this stage the space craft enters the mars sphere of influence which approximately 5, 73,000 km.
