MARS



MARS:

ü  This is one the planets in the solar system.

ü  It is named after the ancient Roman god of war.

ü  The Greeks called it ‘Ares’

ü  It is also called Red planet.

ü  The Greeks and the Romans associated this Mars with war because of its soil’s red  colour resembling the colour of blood.

ü  This is the 4th planet from the Sun. (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune)

ü  The Mars is the closest planet to the earth.

ü  It is 1/6th size of the earth.

ü  Composition of Mars atmosphere:

·         Carbon dioxide – 95.32 percent

·         Nitrogen – 2.7 percent

·         Argon – 1.6 percent

·         Oxygen – 0.13 percent

·         Water vapour – 0.03 percent

·         Nitric Oxide – 0.01 percent


LATEST:


ü  The MOM (Mars Orbiter Mission) or Mangalayan successfully launched by ISRO on November 5, 2013 from Sriharikota, Andhra Pradesh. It was launched through PSLV XL C-25.

    OBJECTIVES OF THE MISSION:

·         To focus on looking for the presence of methane.

·         NOTE: Methane odorless and colourless gas and is widely available in the nature. The presence of it indicates the life.

·         To plan, manage and operate an interplanetary mission

·         Deep space communication, navigation mission planning and management

·         Developing the technologies required for design

ü  The project cost is Rs. 4.5 Billions

ü  The project Director of MOM is M. Annaadurai.

ü  It carried five payloads and all are indigenously made.

·         Lyman-Alpha Photometer (LAP)

·         Methane Sensor For Mars (MSM)

·         Mars Exospheric Neutral Composition Analyzer (MENCA)

·         Thermal Infrared Spectrometer (TIS)

·         Mars Colour Camera (MCC)


LYMAN-ALPHA PHOTOMETER (LAP)

ü  LAP is made by Laboratory for Electro-Optic systems (LOES), Bangalore (Karnataka)

ü  LAP measures the relative amounts of Deuterium to Hydrogen which will help in understanding the loss of water.


METHANE SENSOR FOR MARS (MSM):

ü  MSM is made by Space Application center located in Ahmadabad (Gujarat)

ü  The MSM is assigned to detect the presence of Methane gas which is an indicator of presence of life.

MARS EXOSPHERIC NEUTRAL 


COMPOSITION ANALYZER (MENCA)


ü  MENCA is made by Space Physics Laboratory Thiruvananthapuram (Kerala)

ü  It looks into the exosphere of Mars.


THERMAL INFRARED SPECTROMETER 


(TIS)

ü  TIS is also made by Space Application centre

ü  This provides the information about the origin of Methane whether it comes from biological or geological process.


MARS COLOUR CAMERA (MCC)


ü  MCC helps in optical imaging of Mars surface.


ISTRAC (IRSO TELEMETRY, TRACKING 


AND COMMAND NETWORK):

ü  This is located in Bangalore

ü  After launching the ISTRAC is the nerve centre of the mission

ü  It communicates with the space craft now

ü  According to ISTRAC the satellite goes around the earth once in 6 hours and 50 minutes

ü  By December 1, 2013 the space craft must be put on the path to the Mars


Mars Orbiter Mission is designed for scientific 

exploration. The objective is to develop and test 

technologies necessary for long inter planetary 

mission.
