The longest journey India has ever undertaken is reaching its destination
Mars. After 300 days, 650 million kilometres, the country's Mars Orbiter Mission (MOM) is within striking distance of making big global history.
On the morning of September 24, the Indian space programme makes its much-awaited tryst with the Earth's red neighbour, Mars, with a spacecraft the size of a Tata Nano car, and lovingly called Mangalyaan or Mars Craft. (

The 1350-kilogram unmanned robotic satellite is first slowed down in a tricky manoeuver so that it gets caught in the orbit of Mars - a wee bit slower and it would crash land on the surface of Mars, a wee bit fast and it would miss the Red Planet to be lost in outer space forever. The success rate of such a complex mission is less than 50 per cent and even America and Russia did not succeed in their maiden attempts. Indian Space Research Organisation (ISRO) chairman K Radhakrishnan explains "India will become the first Asian country to have achieved this and if it happens in the maiden attempt itself, India could become the first country in the world to have reached distant Mars on its own steam in the first attempt."
This is undisputedly a shining moment in the space exploration history of a country otherwise beset with developmental challenges. Over half a century, the Indian space programme has managed many feats, but none as dramatic as taking an inter-planetary leap, which is what MOM has accomplished. Partly in keeping with the Asian space race, MOM was conceptualised, planned and implemented by ISRO in the spirit of a 100-metre dash and sticking diligently to a shoestring budget of Rs 450 crores (USD 67 million) - a figure that has surprised many across the world, and prompted the country's newly-elected Prime Minister Narendra Modi to suggest that "the Hollywood movie Gravity cost more than our Mars mission - this is a great achievement."

Perhaps the world's cheapest inter-planetary mission, MOM was a tense, 15-month roller-coaster for the more than 500 engineers and scientists involved. Most global missions take over a decade to execute and cost a lot more - the current and ongoing mission to Mars by NASA called MAVEN has cost USD 670 million. Without doubt, the geopolitics is significant too, with the timing helping India race ahead of China in trying to get to Earth's alluring neighbour. National pride is always a driver for such missions. The journey that began from the Red Fort in old Delhi to the Red Planet will help India tell the world it is a space power to reckon with.
Launched from India's spaceport of Sriharikota along the eastern coast some 100 kilometres north of Chennai on November 5, last year, Mangalyaan was first publicly announced by former Prime Minister Dr Manmohan Singh from the magnificent Red Fort in old Delhi on August 15, 2012.
This was not an easy decision to take, given the incredible complexities and challenges of inter-planetary missions - the distance, the orbital aerobics, the unknown Martian environment. In 54 years, the world has mounted almost as many missions to Mars. Since 1960, the world has seen several space missions launched to the Red Planet, but more than half of these have been failures. The journey is risky and Mars has traditionally been an unfriendly environment for visits by earthly machines. And no nation - apart from the Mars Express mission, Europe's maiden venture to Mars representing a consortium of 20 countries of the European Space Agency - has succeeded in its maiden venture. MOM, obviously, became a trial of ISRO's technological knack for a long journey out beyond the Earth's gravitational field for the first time. That said, it was always to be more than just that, and MOM attempts to also probe some scientific questions, including the most tantalising one of whether we are indeed alone in the Universe or not.
The satellite as Radhakrishnan says is really a "technology demonstrator" and it will morph into a truly scientific mission when in the Martian orbit as it carries some sophisticated equipment. The Mars Colour Camera (MCC) is the 'eye of the mission', meant to capture images and information about the surface features and composition of the Martian surface, and tell the Indian tax payer it was money well spent. The Methane Sensor for Mars (MSM) will measure methane, and if methane is found on Mars, the question about the possibility of life on the Red Planet becomes more exciting. The global scientific community is very excited about India's effort to send the first dedicated methane gas sensor to Mars. The presence of Methane gas, also called 'marsh gas', on Earth is one of the clinching signs of the presence of carbon-based life forms. So in a way, without even landing on Mars, India hopes to provide an answer to that big question - 'Are we alone in this universe?'
The Mangalyaan was hoisted using the Polar Satellite Launch Vehicle on its 24th consecutively successful mission. The rocket itself was about the same weight (320 tonnes) as a fully loaded Boeing Jumbo Jet or 50 fully-grown elephants, and as tall as a 15-storey building.
ISRO's golden wishes for the future include other inter-planetary missions like the Mars mission, a second moon mission, Chandrayaan-2, that hopes to land a rover on the moon's surface possibly in 2017, a flight to the Sun using Aditya and the ambition of putting Indians out in space through the Human Spaceflight Programme. When PM Modi spoke of the Indian space programme, he said: "This is one domain in which we are at the international cutting edge. A domain in which we have pushed beyond mediocrity to achieve excellence". In the next few weeks ISRO will test India's till date most heavy weight rocket the Geosynchronous Satellite Launch Vehicle Mark III and fly a dummy crew module that can carry up to three astronauts in space. ISRO going boldly where angels fear to tread, transforming India into a much sought after sophisticated technological powerhouse.
