Mars Orbiter Mission is India's first interplanetary mission to send an orbiter to Mars. The spacecraft uses proven technology from previous Indian missions, with modifications for communicating with Mars over long distances and restarting the liquid engine after 10 months of travel. It carries scientific instruments to study Mars' surface, atmosphere, and morphology. The mission involves placing the orbiter into Martian orbit through a series of orbit raising maneuvers, and using the orbiter to conduct scientific exploration of Mars from orbit.

2.  Mars Orbiter Mission is India's
first interplanetary mission to
planet Mars with an orbiter craft
designed to orbit Mars in an
elliptical orbit. The Mission is
primarily technological mission
considering the critical mission
operations and stringent

4.  The spacecraft configuration is a balanced mix of design from flight
proven IRS/INSAT/Chandrayaan-1 bus. 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 onboard autonomy.
 390 litres capacity propellant tanks accomodate a maximum of 852 kg
of propellant which is adequate with sufficient margins.
 A Liquid Engine of 440 N thrust is used for orbit raising and insertion in
Martian Orbit.
 Antenna System consists of Low Gain Antenna (LGA), Medium Gain
Antenna (MGA), and High Gain Antenna (HGA). The High Gain Antenna
system is based on a single 2.2 meter reflector illuminated by a feed at
S-band. It is used to transmit/receive the Telemetry, Tracking and
Commanding (TTC) and data to/from the Indian Deep Space Network

5.  Of all the planets in the solar
system, Mars has sparked the
greatest human interest. The
conditions in Mars are believed to be
hospitable since the planet is similar
to Earth in many ways. For
ages, humans have been speculating
about life on Mars. However, the
question that is to be still answered is

7. A. Technological
 Objectives: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.
 Deep space communication, navigation, mission planning and
management.
 Incorporate autonomous features to handle contingency situations.
B. Scientific Objectives:
 Exploration of Mars surface features, morphology, mineralogy and
Martian atmosphere by indigenous scientific instruments.

this morning (Nov 11, 2013), the apogee (farthest point to
Earth) of Mars Orbiter Spacecraft was raised from 71,623 km
to 78,276 km by imparting an incremental velocity of 35
metres/second (as against 130 metres/second originally
planned to raise apogee to about 100,000 [1 lakh] km). The
