    India has successfully launched a spacecraft to the Red Planet - with the aim of becoming the fourth space agency to reach Mars.

    The Mars Orbiter Mission took off at 09:08 GMT from the Satish Dhawan Space Centre on the country's east coast.

    The head of India's space agency told the BBC the mission would demonstrate the technological capability to reach Mars orbit and carry out experiments.

    The spacecraft is set to travel for 300 days and reaching Mars orbit in 2014.

    If the satellite orbits the Red Planet, India's space agency will become the fourth in the world after those of the US, Russia and Europe to undertake a successful Mars mission.

    A 56-hour countdown to the launch began on Sunday.

    What ordinary Indians think of the country's mission to Mars

    Some observers are viewing the launch of the MOM, also known by the informal name of Mangalyaan (Mars-craft), as the latest salvo in a burgeoning space race between the Asian powers of India, China, Japan, South Korea and others.

    Prof Andrew Coates, from the UK's Mullard Space Science Laboratory, told BBC News: "I think this mission really brings India to the table of international space exploration. Interplanetary exploration is certainly not trivial to do, and [India] has found some interesting scientific niches to make some measurements in."

    Those niche areas include searching for the signature of methane (CH4) in the Martian atmosphere, which has previously been detected from Martian orbit and telescopes on Earth. However, Nasa's Curiosity rover recently failed to find the gas in its measurements of atmospheric gases.

    CH4 has a short lifetime in the Martian atmosphere, meaning that some source on the Red Planet must replenish it. Intriguingly, some 95% of atmospheric methane on Earth is produced by microbes, which has led some to propose the possibility of a biosphere deep beneath the Martian surface. But the gas can be produced by geological processes too, most notably by volcanism.

    Definitive conclusions are likely to be elusive, but the spacecraft's Methane Sensor for Mars (MSM) instrument will aim to make measurements and map any potential sources of methane "plumes".

    The spacecraft will also examine the rate of loss of atmospheric gases to outer space. This could provide insights into the planet's history; billions of years ago, the envelope of gases around Mars is thought to have been more substantial.

    India's Mars orbiter mission successfully blasts off!

    NEW DELHI: Creating history, India's Mars orbiter mission blasted off at 2:38 PM from Sriharikota and injected the Mangalyaan into a precise orbit around Earth. The Mission is primarily a technological one, considering the critical operations and stringent requirements on propulsion and other bus systems of spacecraft.

    After leaving the earth's orbit, the spacecraft will cruise in deep space for about ten months using its own propulsion system and will reach Martian transfer trajectory. India's Mars Orbiter is expected to reach the red planet's orbit by September 2014 and look for the presence of methane, an indicator of life there.

    India successful launched it’s first ever mission to the Red Planet – Mars. At 1438 IST from SHAR space port.

    Mars Orbiter Mission is ISRO’s first interplanetary mission to planet Mars with an orbiter craft designed to orbit Mars in an elliptical orbit of 372 km by 80,000 km. Mars Orbiter mission can be termed as a challenging technological mission and a science mission considering the critical mission operations and stringent requirements on propulsion, communications and other bus systems of the spacecraft.

    The primary driving technological objective of the mission is to design and realize a spacecraft with a capability to perform Earth Bound Manoeuvre (EBM), Martian Transfer Trajectory (MTT) and Mars Orbit Insertion (MOI) phases and the related deep space mission planning and communication management at a distance of nearly 400 million Km. Autonomous fault detection and recovery also becomes vital for the mission.

    PSLV would inject the spacecraft from SDSC, SHAR in the 250 X 23000 km orbit with an inclination of 17.864 degree. As the minimum energy transfer opportunity from earth to mars occurs once in 26 months, the opportunity in 2013 demands a cumulative incremental velocity of 2.592 km/sec.

    Here are some key facts about Isro's Mars mission:

    1. This is the first time the national space agency is aspiring to send a mission to study a celestial body outside Earth's sphere of influence.

    2. India's Mars Orbiter is expected to reach the red planet's orbit by September 2014 and look for the presence of methane, an indicator of life there.

    3. Isro has put in place an extensive network of stations worldwide to track the Mars Orbiter Mission after launch from the first launch pad here at 2.38pm.

    4. Unlike other PSLV missions, PSLV C25 will take more than 40 minutes to inject the Mars Orbiter into Earth's orbit as it has a long coasting phase (1,700 seconds) for the launch and has to achieve an "argument" of perigee of 276.4 degrees.

    5. The vehicle trajectory will be tracked by monitoring stations at the Space Centre here, Indian Deep Station Network at Byalulu near Bangalore and Down Range Station at Port Blair in India and also from Biak in Indonesia and Brunei.

    6. Two sea-borne terminals equipped with a 4.6 metre antenna and a 1.8 metre antenna on board Shipping Corporation of India's SCI Nalanda and SCI Yamuna (some 2500 km between them) in South Pacific Ocean will track the vehicle as it injects the Mars Orbiter mission into Earth's orbit.

    7. Once injected into orbit by the launch vehicle, the spacecraft trajectory post separation would be tracked from NASA's Jet Propulsion Laboratory facilities at Goldstone (U.S), Madrid (Spain) and Canberra (Australia).

    8. The Mars Orbiter carries five scientific instruments to study the red planet - Lyman AlphaPhotometer (LAP), Methane Sensor for Mars (MSM), Mars Exospheric Neutral Composition Analyser (MENCA), Mars Colour Camera (MCC) and Thermal Infrared Imaging Spectrometer (TIS).

    9. While LAP and MSM would help in atmospheric studies,MENCA would focus on studying particle environment.MCC and TIS would contribute to studying the surface imaging of the red planet.

    10. After having received 33 ideas for instruments to be flown to Mars, Isro shortlisted nine, of which the Advisory Committee of Space Sciences headed by Prof U R Rao finalised five instruments as only these were mature enough for the flight.

    11. The 1,337 kg Mars Orbiter with 852 kg fuel and 15 kg of scientific instruments is expected to reach Mars' orbit on September 14, 2014.

    12. Though there have been 51 missions to the red planet by some countries, only 21 have been considered successful, according to Nasa.

    Why the hell did ISRO invited a politician?

    He is talking nonsense and crediting the successful launch to Sonia Gandhi....:what:

    Anyway expecting @OrionHunter, PDF inhouse astronomist, to keep us updated on this mission

    India will be the sixth — after the US, Russia, China, Japan and the European Union—to launch a Mars mission. Once launched, the satellite is expected to take more than 40 minutes to get injected into Earth's orbit.

    The orbiter will remain in Earth orbit till December 1 when it starts its 300-day voyage to Mars. It is expected to reach the orbit of the red planet on September 24, 2014, after traversing 400 million km.

    Huge boost for India as a nation if this is successful. Best of luck ISRO!

    Also, Chinese and Japanese Mars missions failed, so if sucessful India will be the 4th successful Mars mission country.

    OK i see. Another fun fact, if successful in this try, India will be the first country to have a successful Mars mission in first try. The remaining 4 countries were successful after 2nd try or later.
