3. INTRODUCTION
The Mars Orbiter
Mission (MOM), informally
called Mangalyaan (Sanskrit:
, "Mars-Craft"), is
a Mars orbiter launched
into Earth orbit on 5 November
2013 by the Indian Space Research
Organisation(ISRO). The mission
is a "technology demonstrator"
project aiming to develop the
technologies required for
design, planning, management
and operations of an
interplanetary mission.
4. OBJECTIVES
Exploration of Martian Surface Features
Morphology
Topography
Mineralogy
Study of Martian Upper Atmosphere
Detect and measure Methane with an accuracy of ppb
Explore the Martian Exosphere (>= 400 km above the surface of Mars)
neutral density and composition
Optical Imaging
Mars
Phobos and Deimos
Context for Science Payloads
5. LAUNCH
The ISRO used its PSLV-XL (Polar Satellite Launch Vehicle)
rocket to launch the Mars Orbiter Mission.[The launch, on 5
November 2013, placed the Mars Orbiter Mission into Earth
orbit. Six orbit raising operations were conducted on 6, 7, 8,
10, 11 and 16 November by using the craft's on-board
propulsion system, which is a derivative of the system used on
India's communications satellites.These manoeuvres raised
the orbit to one with an apogee of 192,000 km and perigee of
252 km , where it will remain for about 15 days. A firing on 1
December 2013 will send MOM onto an interplanetary
trajectory. Mars orbit insertion is planned for 24 September
2014.The Mars Orbiter will have to travel a distance of 780
million kilometers to reach Mars.

8. PSLV XL
The Polar Satellite Launch Vehicle ,
commonly known as PSLV, is an expendable
launch system developed and operated by
the Indian Space Research Organisation (ISRO). It
was developed to allow India to launch its Indian
Remote Sensing (IRS) satellites into sun
synchronous orbits.
PSLV-XL is the uprated version of Polar
Satellite Launch Vehicle in its standard
configuration boosted by more powerful,
stretched strap-on boosters.
9. SPACECRAFT
Mass
The lift-off mass was 1,350 kg , including
852 kg of propellant mass.
Dimensions
Cuboid in shape of approximately 1.5 m .
Power
Electric power is generated by three solar
array panels of 1.8 × 1.4 m each. Electricity is
stored in a 36 Ah Li-ion battery.
Propulsion
Liquid fuel engine of 440 N thrust is used for
orbit raising and insertion in Martian
orbit, and 8 numbers of 22 N thrusters are
used for attitude control .
Communications
Two 230 W TWTAs and two coherent
transponders. The antenna array consists of
a low-gain antenna, a medium-gain
antenna and a high-gain antenna.
10. PAYLOADS
Atmospheric studies
•Lyman-Alpha Photometer (LAP)
•Methane Sensor For Mars (MSM)
Particle environment studies
Mars Exospheric Neutral
Composition Analyser (MENCA)
Surface imaging studies
•Thermal Infrared Imaging
Spectrometer (TIS)
•Mars Color Camera (MCC)
11. LYMAN ALPHA PHOTOMETER (LAP)
Lyman Alpha Photometer (LAP) is an absorption cell photometer. It
measures the relative abundance of deuterium and hydrogen from lymanalpha emission in the Martian upper atmosphere (typically Exosphere and
exobase). Measurement of D/H (Deuterium to Hydrogen abundance Ratio)
allows us to understand especially the loss process of water from the planet.
12. Methane Sensor for Mars (MSM)
MSM is designed to measure Methane (CH4) in the Martian atmosphere with
PPB accuracy and map its sources. Data is acquired only over illuminated
scene as the sensor measures reflected solar radiation. Methane concentration
in the Martian atmosphere undergoes spatial and temporal variations.
13. Mars Exospheric Neutral Composition Analyser (MENCA)
MENCA is a quadruple mass
spectrometer capable of analyzing the
neutral composition in the range of 1
to 300 amu with unit mass
resolution.
14. Thermal Infrared Imaging Spectrometer (TIS)
TIS measure the thermal
emission and can be operated
during both day and night.
Temperature and emissivity are
the two basic physical
parameters estimated from
thermal emission measurement.
Many minerals and soil types
have characteristic spectra in
TIR region. TIS can map surface
composition and mineralogy of
Mars.
15. Mars Color Camera (MCC)
This tri-color Mars color camera gives images & information about the
surface features and composition of Martian surface. They are useful to
monitor the dynamic events and weather of Mars. MCC will also be used for
probing the two satellites of Mars-Phobos & Deimos. It also provides the
context information for other science payloads.
16. TRACKING AND COMMAND
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, and 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.
