The Mars Orbiter Mission (MOM) was ISRO's first interplanetary mission consisting of an orbiter launched in 2013. The orbiter's objectives were to develop technologies for a Mars mission, design an orbiter capable of surviving Earth maneuvers, a 300 day cruise, and Mars orbit insertion and capture. The orbiter carried five science payloads to analyze the Martian atmosphere and surface composition, including imaging cameras and spectrometers. After launching from Earth orbit, the orbiter performed a series of orbit raising maneuvers before the trans-Mars injection burn. It then cruised in heliocentric orbit for over nine months before successfully capturing into orbit around Mars in September 2014.

2. WHAT IS MARS ORBITER MISSION (MOM) ?
• Mars Orbiter Mission is ISRO's First Interplanetary Mission with an Orbiter
craft.
• The Orbiter craft is designed to orbit Mars in an elliptical orbit of 366 km x
80000 km.
• The Mission is to design and realize a spacecraft with a capability to perform
• Earth Bound Manoeuvre
• Martian Transfer Trajectory (MTT)
• Mars Orbit Insertion (MOI), phases.

3. TECHNOLOGICAL OBJECTIVES OF MOM
• To develop the technologies required For design, planning, management, deep
space communication and operations of an Interplanetary Mission.
• To design and realize 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.
• Incorporate autonomous Features to handle contingency situations.

5. PAYLOADS Lyman Alpha Photometer (LAP)
Martian Exospheric Neutral
Composition Explorer
(MENCA)
Mars Colour Camera
(MCC)
Methane Sensor For Mars
(MSM)
Thermal Infra-Red
Imaging Spectrometer
(TIS)

6. LYMAN ALPHA PHOTOMETER (LAP)
a photometer that measures the
relative abundance of
deuterium and hydrogen from Lym
an Alpha Emissions in the upper
atmosphere. Measuring the
deuterium/hydrogen ratio will
allow an estimation of the amount
of water loss to outer space.

7. MARTIAN EXOSPHERIC NEUTRAL COMPOSITION
EXPLORER (MENCA)
is a quadruple mass analyser
capable of analysing the neutral
composition of particles in the
exosphere.

8. MARS COLOUR CAMERA (MCC)
The tri-colour MCC will
provide images and
information of the
surface feature and
composition of Martian
Surface.

9. METHANE SENSOR FOR MARS (MSM)
measure Methane in
the Atmosphere of
Mars if any, and map
its sources

10. THERMAL INFRA-RED IMAGING
SPECTROMETER (TIS)
will measure the
temperature and
emissivity of the
Martian surface,
allowing for the
mapping of surface
composition and
mineralogy of Mars

MOM
1. GEO CENTRIC PHASE: STAGE 1 –
STAGE 6
3. MARTIAN PHASE:
STAGE 8
2. HELIO CENTRIC PHASE: STAGE
7

12. PHASES
• PHASE 1: GEO CENTRIC PHASE
• STAGE 1: Following its launch on 5th Nov 2013 the Mars Orbiter Craft settled into a
“Parking orbit” around the Earth with a Perigee of 248 Km and an Apogee of 23500 Km.
• STAGE 2 : raising the apogee to 28825 Km.
• Stage 3: raising apogee to 40000 Km
• Stage 4 : by 9th Nov 2013 apogee raised by 71500 Km.
• Stage 5 : on 11th Nov Apogee raised to 100000 Km.
• Stage 6 : on 16th Nov Apogee raised to 192000 Km.
• PHASE 2: HALIO CENTRIC PHASE
After the crucial Trans Mars Injection on 1st Dec 2013 at 12: 42 AM
prolonged firing of the 440 Newton Engine catapult the orbiter from the
earth-centric orbit to Sun-centric Orbit.
• PHASE 3: MARTIAN PHASE
The orbiter finally captured into the Martian orbit on 24th Sep 2014 after a
long 9 months coast around the Sun.
