India (ISRO) accomplished a spectacular milestone by launching a satellite orbiting around Mars. The mission has critical significance in the history of Mars missions. These slides cover information about this mission including some awesome tricks used in the mission.

2. Mangalyan
( Mars Orbiter Mission)
 Date Of Announcement : 15 August 2012
 Date Of Launch : 5 November 2013
 Place Of Launch : Satish Dhawan Space Centre
( Sriharikota )
Within 15 months from the announcement, ISRO
developed own indigenous technology, tested different
parts, assembled them and successfully launched as
per plan

4. A Glance At The Trajectory Followed By
MOM

5. Transitions in orbit of Mom
 PSLV rocket took the spacecraft in the Near Earth Orbit also known as LEO ( Lower Earth Orbit )
 Very first orbits in which the spacecraft entered and then raised to higher ones are called EPOs ( Earth
Parking Orbits )
 LEO Perigee : 240 Km LEO Apogee : 24000 Km
 Orbit increment was done when the satellite was at the perigee point
 It has undergone through Orbit Raising Maneuver 5 times
 Final Apogee : 193000 Km Corresponding Speed Of Satellite : ~ 11 Km/sec

6. Transfer orbit of MOM
 Hohmaan transfer orbit: The elliptical heliocentric orbit that is used in interplanetary
travel, with the use of least fuel
 The elliptical transfer orbit’s apsides (the closest and farthest points) are tangential
to both the departing planet’s orbit and the arriving planet’s orbit
 For travel to outer planets, like Mars, the periapsis (closest point in the orbit) must
coincide with Earth’s orbit, while apoapsis must coincide with Mars’ orbit
 The Mars Orbiter Mission (MOM) by the Indian Space Research Organization which is
expected to enter the orbit of the planet Mars soon, used this Hohmann transfer
orbit as its trajectory to reach Mars

7. Transfer orbit of MOM
 Since the satellite is in heliocentric trajectory, the fuel is not
used in this travel
 Fuel is used only to enter the Hohmann transfer orbit from
earth and to exit the transfer orbit to enter martian orbit
 This transfer orbit is thus highly fuel efficient compensating its
long travel time

8. Different Sections Of The Orbiter

9. Payloads On The Orbiter & Their Functions
 LAP ( Lyman Alpha Photometer ): It’s an absorption cell photometer. It
measures the relative abundance of Dueterium & Hydrogen from Lyman-
Alpha emission in the upper Martian atmosphere. Measurement of D/H
allows us to understand the loss process of water from the planet.
 MSM ( Methane Sensor For Mars ): Designed to measure Methane(CH4) in
the Martian atmosphere with PPB accuracy and map its sources
 MENCA ( Mars Exopheric Neutral Composition Analyser ): Quadruple mass
spectrometer capable of analyzing the neutral composition in the of 1 to
300amu with unit mass resolution
 MCC ( Mars Colour Camera ): A tri-colour camera used to take images of
Martian surface. It will be used to take photographs of Phobos & Deimos.
 TIS ( Thermal Infrared Imaging Spectrometer ): Measures the thermal
emission and can be operated during both day & night. Many minerals and
soil types have characteristic spectra in TIS region. It can map surface
composition and mineralogy of Mars.

14. Why is it so appreciable ?
Out of 51 only 21 Mars missions are successful
India is the first Asiatic Nation whose Mars Mission is
successful
India is the first Nation in the world who has achieved
this in the very first attempt only
Cheaper than any other mission to Mars
