Mars Orbitor

Mars Orbiter Mission informally called Mangalyaan 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.

The mars orbiter was launched into earth orbit on 5th November,2013 by ISRO and is expected to enter Orbit around Mars on 24th Sept , 2014 .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 European Space Agency.

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.

Following are the major objectives of the mission:

A. Technological Objectives:
Design and realisation of a Mars orbiter with a capability to survive and perform Earth bound manoeuvres, cruise phase of 300 days, Mars orbit insertion / capture, and on-orbit phase around Mars.
Deep space communication, navigation, mission planning and management.
Incorporate autonomous features to handle contingency situations.

B. Scientific Objectives:
Exploration of Mars surface features, morphology, mineralogy and Martian atmosphere by indigenous scientific instruments.

Mars Orbiter is carrying following Payloads with mentioned objectives :
  • Lyman-Alpha Photometer (LAP) – is an absorption cell photometer that measures the relative abundance of deuterium and hydrogen from Lyman-alpha emissions in the upper atmosphere. Measuring the deuterium/hydrogen ratio will allow us to understand the loss process of water from planet.
  • Methane Sensor For Mars (MSM) – will measure methane in the atmosphere of Mars,and will map its sources.
  • Mars Exospheric Neutral Composition Analyser (MENCA) – is a quadrupole mass analyser capable of analysing the neutral composition of particles in the exosphere.
  • Thermal Infrared Imaging Spectrometer (TIS) – will measure the temperature and emissivity of the Martian surface, allowing for the mapping of surface composition and mineralogy of Mars.
  • Mars Colour Camera (MCC) – will give images and information about surface features and composition of martian surface
