India's Mission To Mars

India's proposed Mars mission in November next year would boost its credentials to take part in possible international collaborative ventures on exploring the Red Planet.

"Besides doing it on its own, the Indian Space Research Organisation (ISRO) will obviously be roped in an international team, including the United States, Europe and other countries (in possible international missions to Mars in future)", former  ISRO Chairman K Kasturirangan, told PTI in Bangalore.

"And so we will have our own credentials to participate effectively in those (possible international) missions (in future)", he said, adding, ISRO's Mars mission next year would qualify the space agency for future missions of international character.


He said several countries would mount several programmes which ultimately make very effective means of exploring Mars in synergy. "If you want to do that, you need several of these elements out of which ISRO's search through its own spacecraft will be one of those elements".

Mr Kasturirangan said Mars missions by different countries are trying to look at areas for landing, search for life, Martian composition and surface dynamics and other kinds of indicators.

"So you need quite a lot (of explorations). Ultimately, we are in-situ not there (on Mars). You need explorations before taking decisions", he added.

According to ISRO officials, the cost of the Mars orbiter mission isRs. 450 crore. The venture's main objective is to demonstrate India's technological capability to reach Martian orbit and it would pave the way for future scientific exploratory missions.

The Mars orbiter is planned for launch using India's Polar Satellite Launch Vehicle (PSLV-XL) from the Satish Dhawan Space Centre, Sriharikota.
After a successful moon mission, the Union Cabinet gave the go-ahead to India's first mission to Mars. The Cabinet, at a meeting chaired by Prime Minister Manmohan Singh on Friday, cleared the proposal of Department of Space to put a satellite in an orbit around Mars to study the Red Planet, sources said.

If the mission succeeds, India will be the sixth country to do so after US, Russia, Europe, Japan and China.

The Indian Space Research Organisation (ISRO) is expected to launch a Mars Orbiter as early as November next year with a 25kg scientific payload. A rocket will blast off from the south-eastern coast of India, dropping the satellite into deep space, which will then travel onto Mars to achieve orbit, a senior scientist said. ISRO scientists expect the satellite to orbit at less than 100 km (62 miles) above Mars.
The Rs. 450-crore mission is expected to be launched from India's spaceport - Sriharikota in Andhra Pradesh - and will take nearly 300 days to reach the Martian orbit.

The Mars mission, which will study its atmosphere, will be launched by an extended version of ISRO's warhorse rocket - the Polar Satellite Launch Vehicle (PSLV). 

If the ISRO fails to launch the Mars Mission next year, other opportunities are available in 2016 and 2018. The orbiter will be placed in an orbit of 500 x 80,000 km around Mars and has a tentative scientific objective for studying the climate, geology, origin, evolution and sustainability of life on the planet.

Scientific payloads have been short-listed by ISRO's Advisory Committee for Space Sciences (ADCOS) review committee.

Baseline, solar array and reflector configuration of the satellite have been finalised. 

The plan has drawn criticism in a country suffering from high levels of malnutrition and power shortages. But India has long argued that technology developed in its space programme has practical applications to everyday life.

India's space exploration programme began in 1962. Four years ago, its Chandrayaan satellite found evidence of water on the moon. India is now looking at landing a wheeled rover on the Moon in 2014.

Last year, a Chinese Russian probe failed in a bid to send a satellite to Mars.
The November 2013 launch would allow the spacecraft to enter a highly elliptical orbit of 500 km x 80,000 km around Mars in September 2014. The proposed payload of 25 kg consists of ten instruments, including:
  • Probe For Infrared Spectroscopy for Mars (Prism)
  • Mars Exospheric Neutral Composition Analyzer (Menca)
  • "TIS" instrument (thermal emissions)
  • Mars Color Camera (MCC)
  • Methane Sensor For Mars (MSM)
  • Mars Radiation Spectrometer (Maris)
  • Plasma and Current Experiment (Pace)
