AHMEDABAD: Two spacecrafts will reach theMars orbit within days of each other in September 2014. Despite the same destination, they carry vastly different price tags.
The US craft MAVEN has been developed for $485 million while the Indian craft Mangalyaan has cost Isro just $69 million. The world's scientific community is now focusing on the Indian mission as it would set many benchmarks for the future.
"We took successful components from the Chandrayaan I moon mission and improvised and upgraded them for the Mars mission saving on cost and time," said Somya Sarkar, one of four principal investigators for the Mars mission at Isro's Space Application Centre (Sac), Ahmedabad.
Sarkar along with Kurian Mathew, Ashutosh Arya and R P Singh developed three of the five payloads of Mangalyaan.
The challenge was to keep the weight of the payload at 15 kg. Any extra weight would have meant India having to opt for a costlier launch vehicle instead of the Polar Satellite Launch Vehicle (PSLV). In the end, Sac Ahmedabad contributed just 7.5 kg to the payload.
But it is not just weight reduction and the price tag that has excited scientists. Many of the innovations are path-breaking. For instance, the methane sensors are equipped with a differential radiometer. Mangalyaan will be able to detect extremely low levels of methane gas around mars using this radiometer. The gas is seen as an indicator of the presence of microbial life on the Red Planet.
"My team is confident that the sensors will contribute significantly towards finding the source and amounts of methane gas around Mars, which is important towards understanding if the planet could support life," said Mathew. A thermal infrared imaging spectrometer developed by Singh's team will also be used by the craft.
ISRO's first high resolution colour camera developed by Arya's team will take images of Mars surface from the nearest and farthest point while orbiting Mars. So far Indian space scientists have only taken black-and-white images of celestial objects.
