    Great Facts about Mangalayaan – Mars Orbiter Mission

    Before looking at the facts… let me tell you interestingly primary things to know about Mangalayaan

    Mangalayaan – Mars Orbiter Mission Stages and Info

    ISRO (Indian Space Research Organization) has taken just 18 months in building its rocket, its space craft, instruments and readying its tracking system at Byalalu near Bangalore.

    About the Mangalayaan MOM launch

    The Mars Orbiter Mission, informally known as “Mangalyaan”, was announced 15 months ago by Prime Minister Manmohan Singh shortly after a Chinese probe flopped when it failed to leave earth’s atmosphere.

    The timing led to speculation that India was seeking to make a point to its militarily and economically superior neighbour, despite denials from ISRO.

    The spacecraft was carried onboard the indigenous PSLV-C25 rocket which injected it into Earth’s orbit after 40 minutes from lift-off.

    Lacking the power to fly directly, The 350-tonne launch vehicle will orbit earth for nearly a month, building up the necessary velocity to break free from our planet’s gravitational pull.

    Only then it will begin the second stage of its nine-month journey which will test India’s scientists to the full, five years after they sent a probe called Chandrayaan to the moon.

    The total cost of the project is just 4.5 billion rupees ($73 million), a fraction of foreign equivalents.

    There have been recent setbacks for India, however, including when Chandrayaan lost contact with its controllers in 2009 and when a new larger launch vehicle blew up after take-off in 2010.

    India has never before attempted an inter-planetary journey which has required the development of technology enabling the probe to run autonomously. Communication signals take 12 minutes to travel between Earth and Mars.

    “The biggest problem is to understand the navigation issue from the earth’s orbit to the Martian orbit,” ISRO chief Radhakrishnan said.

    ISRO said that its technology has helped with economic development through satellites which monitor weather and water resources, or enable communication in remote parts of the country.

    The 1,350-kilogram unmanned orbiter must travel 485 million miles over 300 days to reach the red planet.
    The Mars Orbiter is expected to reach Mars’ orbit on September 14, 2014.

    10 Facts about Mangalayaan – Mars Orbiter Mission

    Fact 1 Mangalyaan, which means “Mars craft” in Hindi took off at 2:38 pm on 5th November,2013 from Satish Dhawan Space Centre, Sriharikota(Andhra Pradesh),
    80 kilometres from Chennai (Tamilnadu).
    Fact 2 India became only the fourth country or group of countries to reach the Red Planet,
    after the Soviet Union, United States and Europe.
    Fact 3 This is India’s first Mars mission, and no country has been fully successful on its first try.
    More than half the world’s attempts to reach Mars – 23 out of 40 missions – have failed,
    including missions by Japan in 1999 and Japan’s in 2003, China’s in 2011
    Fact 4 An evolved version of India’s domestically developed Polar Satellite Launch Vehicle, with extended rockets,
    will take Mangalyaan into an elliptical arc around the Earth.
    The satellite’s thrusters will then begin a series of six small fuel burns,
    moving it into higher orbit before it slingshots toward the Red Planet.
    Fact 5 Mangalyaan has a formidable itinerary:
    a 300-day, 780 million-kilometre (485 million-mile) journey to orbit Mars and survey its geology and atmosphere.
    Fact 6 At its closest point it will be 365 kilometres (227 miles) from the planet’s surface,
    and at its furthest – 80,000 kilometres (49,700 miles).
    Fact 7 Five solar-powered instruments aboard Mangalyaan will gather data to help determine
    how Martian weather systems work and what happened to the water that is believed to have once existed
    on Mars in large quantities.
    Fact 8 Mangalyaan will also search Mars for methane,
    a key chemical in life processes on Earth that could also come from geological processes.
    Fact 9 None of the instruments will send back enough data to answer these questions definitively,
    but experts say the data are key to better understanding how planets develop geologically,
    what conditions might make life possible and where else in the universe it might exist.
    Fact 10 In 2008-09, the Indian Space and Research Organisation successfully launched a lunar orbiter,
    Chandrayaan-1, which discovered evidence of water on the moon.
    Mangalyaan was developed from technology tested during the Chandrayaan mission.
