INTRODUCTION

Mars

Mars is the seventh largest planet in our solar system.

Average Distance from Sun: 2.279 x 108 km

Mars is named after the Roman god of war.

The equatorial radius of Mars is 3,397 km.

The diameter of Mars measures 6,794 km.

Atmospheric components on Mars consists of 95% carbon dioxide, 3% nitrogen, 1.6% argon.

Average Surface Temperature: 53 degree celsius

Why Mars is most discovered?

Natural conditions are similar to Arctic & Antarctic zones of Earth.

Surface conditions are habitable.

Similar geology as compared to Earth.

Availability of Water in the form of Ice & Glaciers.

The First Rover Mars Pathfinder was the first instrumented lander and

robotic rover to study the surface of Mars. Findings from the investigations carried out by scientific

instruments on both the lander and the rover suggest that Mars was at one time in its past warm and wet, with water existing in its liquid state and a thicker

atmosphere.

BRIEF HISTORY• The government of india approved the project on 3

August 2012.• The spacecraft structure and propulsion hardware

configurations are similar to Chandrayaan 1, India's first successful robotic lunar probe .

• If successful, ISRO would become the fourth space agency to reach Mars, after Roscosmos, NASA and ESA.

OBJECTIVESTechnological Objectives• Design and realisation of a Mars orbit• Incorporate autonomous features to handle

contingency situations.Scientific Objectives • Study Of Mars surface features• Morphology• Mineralogy • Study Of Martian atmosphere.

LAUNCH AND ORBIT• launched from SDSC Sriharikota by PSLV XL C25 on November

5 2013 and the Mars Orbiter will be placed into Earth orbit, then six engine firings will raise that orbit to one with an apogee of 215,000 km and a perigee of 600 km, where it will remain for about 25 days.

• A final firing in 30 November 2013 will send MOM onto an interplanetary trajectory.

• Mars orbit insertion is planned for 21 September 2014 and would allow the spacecraft to enter a highly elliptical orbit of 372 km x 80,000 km around Mars.

PSLV(POLAR SATELLITE LAUNCH VEHICLE)

• The Polar Satellite Launch Vehicle commonly known by its abbreviation PSLV

• It is an expendable launch system developed and operated by the Indian Space Research Organization (ISRO).

• It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun synchronous orbits.

TRAJECTORY

PAYLOADS

The 15 kg (33 lb) scientific payload consists of five instruments:

• Atmospheric studies Lyman-Alpha Photometer (LAP) Measuring the deuterium/hydrogen ratio will allow to estimate the process of water loss to outer space.

• Methane Sensor For Mars (MSM) to check for methane in the atmosphere of Mars, if any, and map its sources.

• Mars Exospheric Neutral Composition Analyzer (MENCA) — is a quadrupole mass analyzer capable of analyzing the neutral composition of particles in the exosphere.

• Surface imaging studies Thermal Infrared Imaging Spectrometer (TIS) — will measure the temperature and emissivity of the Martian surface, this can allow mapping surface composition and mineralogy of Mars.

• Mars Colour Camera (MCC) — will provide images in the visual spectrum, providing context information for the other science instruments

The Indian Space Research Organisation Telemetry, Tracking and Command Network performed navigation and tracking operations for the launch with ground stations at Sriharikota, Port Blair, Brunei and Biak in Indonesia.

after the spacecraft's apogee becomes more than 100,000 km, two large 18-metre and 32-metre diameter antennas of the Indian Deep Space Network will be utilised.

NASA's Deep Space Network will provide position data through its three stations located in Canberra, Madrid and Goldstone on the U.S. West Coast during the non-visible period of ISRO's network.

TRACKING & COMMAND

CONCLUSION

MOM will explore the Red planet’s Atmosphere
