MANGALYAAN Mars Orbiter Mission:

MANGALYAAN Mars Orbiter Mission Shivaji choudhury


Mangalyaan The Mars Orbiter Mission (MOM), informally called Mangalyaan (Sanskrit for "Mars-Craft"), is a Mars orbiter launched into Earth orbit on 5 November 2013 by the Indian Space Research Organisation (ISRO). Spacecraft Successfully enters Martian Orbit on 24-09-2014

Objectives of the mission: :

Objectives of the mission: 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.

 Mission Plan :

 Mission Plan The Launch Vehicle - PSLV-C25 will inject the Spacecraft into an Elliptical Parking Orbit with a perigee of 250 km and an apogee of 23,500 km. With six Liquid Engine firing, the spacecraft is gradually maneuvered into a hyperbolic trajectory with which it escapes from the Earth’s Sphere of Influence (SOI) and arrives at the Mars Sphere of Influence. When spacecraft reaches nearest point of Mars (Peri-apsis), it is maneuvered in to an elliptical orbit around Mars by firing the Liquid Engine. The spacecraft then moves around the Mars in an orbit with Peri-apsis of 366 km and Apo-apsis of about 80000 km.

Spacecraft The spacecraft configuration is a balanced mix of design from flight proven IRS/INSAT/Chandrayaan-1 bus. Modifications required for Mars mission are in the areas of Communication, Power, Propulsion systems (mainly related to Liquid Engine restart after nearly 10 months) and on-board autonomy.


Payload 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, especially the related geologic and the possible biogenic processes on that interesting planet. These payloads consist of a camera, two spectrometers, a radiometer and a photometer. Together, they have a weight of about 15 kg.

 Launch Vehicle - PSLV-C25 :

 Launch Vehicle - PSLV-C25 The Mars Orbiter Mission probe lifted-off from the First Launch Pad at Satish Dhawan Space Centre SHAR, Sriharikota, Andhra Pradesh, using a Polar Satellite Launch Vehicle (PSLV) rocket C25 at 09:08 UTC (14:38 IST) on 5 November 2013.

 Ground Segment :

 Ground Segment ISRO Telemetry Tracking and Command Network (ISTRAC) will be providing support of the TTC ground stations, communications network between ground stations and control center, Control center including computers, storage, data network and control room facilities, and the support of Indian Space Science Data Center (ISSDC) for the mission. The ground segment systems form an integrated system supporting both launch phase, and orbital phase of the mission.
