New Delhi: Launched on September 24, 2014, with an intent to probe the Red Planet, India's Mangalyaan spacecraft that was estimated to last for 6 months has now completed 3 whole years.
The Indian Space research Organisation's (ISRO) Mars Orbiter Mission (MOM) has been one of the most celebrated probes and also completed 1000 Earth days in Martian orbit in June this year, well beyond its designed mission life of 180 days.
The spacecraft is expected to circle the planet for another five years as it has still got about 15kg of fuel left.
"As the country's low-cost Mars Orbiter Mission completes three years in its Martian orbit, the satellite is in good health and continues to work as expected," ISRO said.
The scientific analysis of the data received from the Mars Orbiter spacecraft is in progress, ISRO Public Relations Director Deviprasad Karnik told PTI.
The country had on September 24, 2014 successfully placed the Mars Orbiter Mission spacecraft in the orbit around the red planet, in its very first attempt, thus breaking into an elite club. ISRO had launched the spacecraft on its nine-month-long odyssey on a homegrown PSLV rocket from Sriharikota in Andhra Pradesh on November 5, 2013. It had escaped the earth's gravitational field on December 1, 2013.
On the occasion of completion of three years of MOM in its Martian orbit on 24 September 2017, the space body today released MOM second year science data from September 24, 2014 to September 23, 2016. The space agency had earlier launched MOM Announcement of Opportunity (AO) programmes for researchers in the country to use MOM data for research and development.
Citing surplus fuel, ISRO had in March, 2015 announced that the spacecraft's life had been extended for another six months. Later in June, 2015, its chairman A S Kiran Kumar had said it had enough fuel for it to last "many years". The Rs 450-crore MOM mission aims at studying the Martian surface and mineral composition as well as scan its atmosphere for methane (an indicator of life on Mars).
The Mars Orbiter has five scientific instruments – Lyman Alpha Photometer (LAP), Methane Sensor for Mars (MSM), Mars Exospheric Neutral Composition Analyser (MENCA), Mars Colour Camera (MCC) and Thermal Infrared Imaging Spectrometer (TIS).
The Mars Colour Camera, one of the scientific payloads onboard MOM, has produced more than 715 images so far, ISRO had said. During its journey so far, the mission went through a communication 'blackout' as a result of solar conjunction from June 2, 2015 to July 2, 2015. It had also experienced the 'whiteout' geometry phenomenon (when earth is between the sun and Mars and too much solar radiation makes it impossible to communicate with the earth) from May 18 to May 30, 2016.
An orbital manoeuvre was also performed on MOM spacecraft to avoid the impending long eclipse duration for the satellite, ISRO said. The government had in November last said the space organisation was seeking scientific proposals for Mars Orbiter Mission-2 to expand inter-planetary research.
