INDIAN-MARS ORBITER MISSION (MOM) SUCCESSFULLY ENTERED INTO MARS ORBIT




  “When the whole world is silent, even one voice becomes powerful”





Mars Orbiter Mission successfully entered orbit around Mars .
ISRO'S mars orbiter Mission Spacecraft Successfully Entered Into mars Orbit

GREAT ACHIEVEMENTS FOR INDIA AND WHOLE WORLD
MARS ORBITER MISSION Success makes India the fourth space power after the United States, Europe and Russia to orbit or land on the red planet.The Mars orbital successful mission makes India the first Asian nation to reach Mars, and with MOM success India becomes the first country to go to Mars in the first (maiden) attempt.

Given the high rate of failures –only 21 of the total of 51 missions sent to Mars by various countries being successful– the success of MOM in the very first attempt boosted India’s global position in Space.

The spacecraft, India’s Mars Orbiter Mission also called Mangalyaan( Mangalyaan,  means “Mars craft” in Hindi), like MAVEN, Mangalyaan was launched  in November 2013.

India's orbiter around Mars will study the presence of methane in the atmosphere, looking for clues that might indicate former life on the Red Planet.







  OBJECTIVES OF INDIAN MARS ORBITER MISSION(MOM)



One of the main objectives of the first Indian mission to Mars is to develop the technologies required for design, planning, management and operations of an interplanetary mission.

Following are the major objectives of the mission:







A. Technological Objectives Of Mars mission of India:




•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 of Mars Orbiter Mission:
•Exploration of Mars surface features, morphology, mineralogy and Martian atmosphere by indigenous scientific instruments.

                                5 Payloads

Mars Orbiter Mission carries five scientific payloads to observe Martian surface, atmosphere and exosphere . These payloads consist of a camera, two spectrometers, a radiometer and a photometer. Together, they have a weight of about 15 kg.

PayloadPrimary Objective Weight K.g
Lyman Alpha Photometer (LAP)
Study of Escape processes of Martian upper atmosphere through Deuterium/Hydrogen
1.97
Mars Enospheric Neutral Composition Analyser (MENCA)
Study of the neutral composition of Martian upper atmosphere
3.56
Methane Sensor for Mars (MSM)
Detection of Methane presence
2.94
Mars Colour Camera (MCC)
Optical imaging
1.27
Thermal Infrared Imaging Spectrometer(TIS)
Map surface composition and mineralogy
3.2


India has become a low-cost alternative for launching satellites. The Indian Space Research Organization sent five foreign satellites into orbit in May, indicating its potential to capture some of the world's $300 billion annual space business.

COMPARISON BETWEEN EARTH AND MARS

MARS FACTS


Mars Orbiter Mission/Mangalyaan is the cheapest inter-planetary mission in the world. 

India’s Mars mission has a price tag of about $74 million, a fraction of the $671 million cost of the U.S. National Aeronautics and Space Administration’s latest Mars program.


"This has been a cheap mission. But we have not compromised; we have done it in two years and ground testing has helped," said K Radhakrishnan, Chairman of ISRO.


Mangalyaan is the cheapest inter-planetary mission ever to be undertaken anywhere in the world. It has cost Rs. 450 crores or just about Rs. 4 per person in India. India is paving the way for faster, cheaper and possibly durable inter-planetary missions.

A team of 14 ISRO scientists is credited as being the brain behind this mission.

SCIENTISTS NAMEPOSITION/CONTRIBUTION
K Radhakrishnan
He is the Chairman of ISRO and Secretary in department 
of space. He was responsible for leading the mission 
and overall activities of ISRO. 
M Annadurai
He is the Programme Director of Mars Orbiter Mission.
S Ramakrishnan
He is the Director of Vikram Sarabhai Space Centre 
and Member Launch Authorisation Board. played a
 key role in the development of PSLV and was 
responsible for development of liquid propulsion 
stages and their interfacing with vehicle and launch operations.
SK ShivakumarHe holds the position of the Director of ISRO Satellite Centre. 
He was responsible for developing satellite technology 
and implementing satellite systems for scientific, 
technological and application missions.
P Kunhikrishnan
The project director of PSLV programme and was 
appointed as mission director for the ninth time .He is 
the mission director of PSLV-C25/Mars Orbiter Mission, 
scheduled to be launched on November 5. He was
 responsible for seeing the rocket completes its
 mission successfully and that the satellite is correctly
 injected in the designated orbit.
Chandradathan
He is the Director of Liquid Propulsion system. He joined
 ISRO in 1972. Made rich contribution to the realisation]
 of solid motors for sounding rockets, SLV-3, ASLV and PSLV.
 AS Kiran Kumar
The Director of Satellite Application Centre joined 
ISRO in 1975. He has contributed to the design and 
development of Electro-Optical Imaging Sensors for 
Airborne, LEO and GEO platform based imaging 
sensors starting from Bhaskara TV payload to the
 latest TMC adHySI payloads for Chandrayaan-1 missions.

He was responsible for designing and building three
 of the orbiter payloads - Mars Colour Camera, 
Methane Sensor and Thermal Infrared Imaging 
Spectrometer. The challenge before him was 
miniaturising the components as the satellite does not provide much space.
 MYS PrasadHe is the Director of Satish Dhawan Space Centre and 
Chairman of the Launch Authorisation Board. He was 
responsible for range safety and schedules, overall in-charge at rocket port.
 S Arunan
The Project Director of Mars Orbiter Mission and
 was responsible for leading a team to build the spacecraft.
B Jayakumar
He is the Associate Project Director of PSLV project. 
He is responsible for the rocket systems, testing till 
the final lift-off.
MS Pannirselvam
The Chief General Manager of range operation
 director at Sriharikota Rocket port was responsible
 for maintaining launch schedules without any slippages.
