Mars Orbiter Mission is India’s first interplanetary mission to planet Mars with an orbiter craft designed to orbit Mars in an elliptical orbit.
One of the main objectives of the first Indian mission to Mars is to develop the technologies required for design, planning, management and operations of an interplanetary mission.
The mission consists of following three phases:
1. Geo Centric Phase
The spacecraft is injected into an Elliptic Parking Orbit by the launcher.
2. Helio Centric Phase
The spacecraft leaves Earth in a direction tangential to Earth’s orbit and encounters Mars tangentially to its orbit. The flight path is roughly one half of an ellipse around sun.
3. Martian Phase
The spacecraft arrives at the Mars Sphere of Influence (around 573473 km from the surface of Mars) in a hyperbolic trajectory.
ISRO plans to launch the Mars Orbiter Mission during the November 2013 window utilizing minimum energy transfer opportunity.
Mars Orbiter Mission carries five scientific payloads to observe Martian surface, atmosphere and exosphere extending up to 80,000 km for a detailed understanding of the evolution of that planet.Payloads consist of a camera, two spectrometers, a radiometer and a photometer. Together, they have a weight of about 15 kg.
