How the Mars mission helps India

If all goes well, India's space agency will become the fourth in the world to undertake a successful Mars mission

India's launch of a small unmanned satellite to Mars is being described as a giant leap for its space programme. Science writer Pallava Bagla writes on what the mission means for India and the world.

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


India's 1,350kg (2,976lb) robotic satellite which is undertaking the 10-month-long, over 200-million-kilometre journey to Mars is equipped with five instruments.

They include a sensor to track methane or marsh gas - a possible sign of life - on Mars, a colour camera for taking pictures, and a thermal imaging spectrometer to map the surface and mineral wealth of the planet. The mission will also analyse the thin Martian atmosphere.

'Natural progression'
After India's successful unmanned Chandrayaan mission to the Moon in 2008 that brought back the first clinching evidence of the presence of water there, the Mars mission, according to K Radhakrishnan, chairman of the Indian Space Research Organisation (Isro), is a "natural progression".

More than 500 scientists from the Bangalore-based Isro worked round the clock on this $100m (£62.4m) mission, which was announced by PM Manmohan Singh in August last year.

Project chief Subbiah Arunan says he has not taken a vacation in the last 15 months, sleeping at Isro's satellite centre in Bangalore and going home for "about one or two hours every day".

So does India's Mars mission mark the beginning of a new Asian space race?

India sees the Mars mission as an opportunity to beat its regional rival China in reaching the planet, especially after a Russian mission carrying the first Chinese satellite to Mars failed in November 2011. Japan also failed in a similar effort in 1998.

China has beaten India in space in almost every aspect so far: it has rockets that can lift four times more weight than India's, and in 2003, successfully launched its first human space flight which India has not yet embarked on. China launched its maiden mission to Moon in 2007, ahead of India.

So if India's mission succeeds, it will have something to feel proud about.
