Mars Orbiter Mission
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:
1. 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.
2. Deep space communication, navigation, mission
planning and management.
3. Incorporate autonomous features to handle
B. Scientific Objectives:
1. Exploration of Mars surface features, morphology,
mineralogy and Martian atmosphere.
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
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
The spacecraft configuration is a balanced
mix of design from flight proven
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.
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
Together, they have a weight of about 15

MOM will search for methane, a key target
for researchers hunting for signs of life on
Living things produce more than 90
percent of the methane in Earth's
atmosphere. And the gas is thought to
disappear relatively quickly from Mars' air,
meaning that any methane spotted there
would have been produced recently.

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.

Hahmann transfer orbit
A Hohmann transfer orbit
can take a spacecraft from
Earth to Mars.
The orbit is an elliptical
one, where the periapsis is
at Earth's distance from the
Sun and the apoapsis is at
Mars' distance from the
The transfer orbit has to be
timed so that when the
spacecraft departs Earth, it
will arrive at its orbit
