4. 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

5. 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.

6. 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.

7. 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 .
• Since being successful in its first attempt, ISRO has
become the fourth space agency to reach Mars, after
Roscosmos, NASA and ESA.

8. OBJECTIVES
Technological 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.

9. LAUNCH AND ORBIT
• launched from SDSC Sriharikota by PSLV XL C25 on November
5 2013 and the Mars Orbiter was placed into Earth orbit, then
six engine firings raised that orbit to one with an apogee of
215,000 km and a perigee of 600 km,where it remained for
about 25 days.
• A final firing in 30 November 2013 sent MOM onto an
interplanetary trajectory.
• Mars orbit insertion was planned for 21 September 2014 and
it allowed the spacecraft to enter a highly elliptical orbit of
372 km x 80,000 km around Mars.

10. 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.

11. TRAJECTORY

12. 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.

13. • 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

14. 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.

15. CONCLUSION
MOM will explore the Red planet’s
Atmosphere
