The Mars Orbiter Mission (MOM), informally called Mangalyaan (Sanskrit: मंगलयान, "Mars-Craft"), is aMars orbiter launched into Earth orbit on 5 November 2013 by the Indian Space Research Organisation(ISRO).[9][10][11][12] The mission is a "technology demonstrator" project aiming to develop the technologies required for design, planning, management and operations of an interplanetary mission.[13] The Mars Orbiter Mission probe lifted-off from the First Launch Pad at Sriharikota, Andhra Pradesh nearChennai, using a Polar Satellite Launch Vehicle (PSLV) rocket C25 at 09:08 UTC (2:38 PM IST) on 5 November 2013.[14] The launch window was approximately 20 days long and started on 28 October 2013.[5]It is India's first interplanetary mission and if successful, ISRO would become the fourth space agency to reach Mars, after the Soviet space program, NASA, and European Space Agency.[15] The MOM probe is currently in Earth orbit where it is in a month-long process of making six altitude-raisingorbital manoeuvres before a planned insertion into a heliocentric Mars transfer orbit on 1 December 2013 (UTC).

The MOM mission began with a feasibility study in 2010, after the launch of lunar satellite Chandrayaan-1in 2008.[16] The government of India approved the project on 3 August 2012,[17] after the Indian Space Research Organisation completed 125 crore (US$19 million) of required studies for the orbiter.[18] The total project cost may be up to 454 crore (US$69 million).[9][19] The satellite costs 153 crore(US$23 million) and the rest of the budget has been attributed to ground stations and relay upgrades that will be used for other ISRO projects.[20] The space agency had initially planned the launch on 28 October 2013 but was postponed to 5 November 2013 following the inability of ISRO's spacecraft tracking ships to take up pre-determined positions due to poor weather in the Pacific Ocean.[5] Launch opportunities for a fuel-saving Hohmann transfer orbit occur about every 26 months, in this case, 2016 and 2018.[21] The Mars Orbiter's on-orbit mission life will be between six and ten months. Assembly of the PSLV-XL launch vehicle, designated C25, started on 5 August 2013.[22] The integration of the five scientific instruments was completed at ISRO Satellite Centre, Bangalore, and the finished spacecraft was shipped to Sriharikotta on 2 October 2013.[22] The satellite's development was fast-tracked and completed in a record 15 months.[23] Despite the U.S. federal government shutdown, NASA reaffirmed on 5 October 2013 it would provide communications and navigation support to the mission.[24] ISRO chairman stated in November 2013 that if the MOM and NASA's orbiter MAVEN were successful, they would complement each other in findings and help understand Mars better.[25] P. Kunhikrishnan was the PSLV-XL...
