In November 2008, G. Madhavan Nair stood before the public to announce an uncrewed mission to Mars. This marked the first official acknowledgment of India's ambition to reach the Red Planet. The concept for this mission began with a feasibility study conducted in 2010 by the Indian Institute of Space Science and Technology. That study followed the successful launch of the Chandrayaan-1 lunar satellite in 2008. Prime Minister Manmohan Singh gave his final approval on the 3rd of August 2012 after ISRO completed all required studies. The total project cost was estimated at up to 450 Crore rupees. This budget included the satellite itself and funds allocated for ground station upgrades used for other projects.
Launch And Maneuvers
The Mars Orbiter Mission probe lifted off from the First Launch Pad at Satish Dhawan Space Centre on the 5th of November 2013. A Polar Satellite Launch Vehicle designated C25 carried the spacecraft into space at 09:08 UTC. The launch window had been open since the 28th of October 2013 but faced delays due to poor weather affecting tracking ships in the Pacific Ocean. The probe spent about a month orbiting Earth while performing seven apogee-raising maneuvers. These burns utilized the Oberth effect to gradually increase altitude before trans-Mars injection occurred on the 30th of November 2013. The spacecraft traveled approximately 780 million kilometers over a 298-day transit period. It finally entered Martian orbit on the 24th of September 2014 after a complex series of orbital adjustments.
