Mars mission scaled down, will have less experimental payload
The Mars Orbiter Mission, expected to be launched in mid-October this year, will carry five experimental payloads with a total weight of 14.49 kg.
The Methane Sensor for Mars, which will be capable of scanning the entire Martian disc within six minutes, will weigh 3.59 kg, it was revealed at a presentation made by
planetary scientists at the 10th Indian Science Congress here.
Earlier missions to Mars had detected Methane in the thin Martian atmosphere but the discovery is yet to be corroborated.
Methane is known to be released by some microbes as part of their digestive process.
The Mars mission will propel India to the elite club of five nations comprising the US, Russia, Europe, China and Japan which have launched similar missions.
Another instrument--Thermal Infrared Spectrometer-- weighing four kg will be used to map the surface composition of Mars. The Mars Colour Camera has a mass of 1.4 kg, while the Lyman-alpha photometer, weighing 1.5 kg would measure
atomic hydrogen in the Martian atmosphere.
The Mars Exospheric Neutral Composition Analyser (MENCA) which would study the Martian atmosphere weighs about four kg.
All the payloads together weigh 14.49 kg. The Mars orbiter will go around the planet once in three days, its nearest point being only 371 km from the planet's surface and the farthest point about 80,000 km away.
