L'agence spatiale se donne pour objectif de lancer sa sonde spatiale au cours de la fenêtre de lancement qui s'ouvre fin octobre 2013 ce qui impose un cycle de fabrication et de test particulièrement court pour ce type d'engin (15 mois). Les télécommunications passent par une antenne parabolique à grand gain fixe de 2,2 mètres de diamètre déployée en orbite avec les panneaux solaires. Le 24 septembre 2014, après un transit d'une durée de dix mois, la sonde spatiale utilise avec succès sa propulsion principale pour réduire sa vitesse de 1 098,7 m/s et s'insérer sur une orbite de 78 500 × 427 kilomètres autour de la planète Mars proche de celle visée (80 000 × 500 kilomètres)[13]. Un article de Wikipédia, l'encyclopédie libre. L'Inde est la quatrième puissance spatiale à disposer d'un engin spatial martien devançant la Chine et le Japon. MARS ORBITER MISSION Marking India's first venture into the interplanetary space, MOM will explore and observe Mars surface features, morphology, mineralogy and the Martian atmosphere. After the lander’s mission (lasting three months), MCO would have performed a two-year independent mission to monitor atmospheric dust and water vapor and take daily pictures of the planet’s surface to construct an evolutionary map of climatic changes. The high-gain antenna system is based on a single 2.2-metre (7 ft 3 in) reflector illuminated by a feed at S-band. Over these years, MOM's Mars Colour Camera has captured over 980 images that were released to the public. [38], Some of the scientists and engineers involved in the mission include:[39], The total cost of the mission was approximately ₹450 Crore (US$73 million),[40][41] making it the least-expensive Mars mission to date. [105], In March 2016, the first science results of the mission were published in Geophysical Research Letters, presenting measurements obtained by the spacecraft's MENCA instrument of the Martian exosphere. [109], On 19 May 2017, MOM reached 1,000 days (973 sols) in orbit around Mars. The second trajectory correction manoeuvre was performed on 11 June 2014 at 11:00 UTC by firing the spacecraft's 22 newton thrusters for 16 seconds. She has worked on 14 missions over 20 years at ISRO and is the Project Manager, Mission Designer apart from serving as deputy operations director on the Mars Orbiter Mission.

[104], A 17-day communications blackout occurred from 6 to 22 June 2015 while Mars' orbit took it behind the Sun from Earth's view. Bill Dunford, International Space Station Transits the Moon (2018). [27] The MOM mission concept began with a feasibility study in 2010 by the Indian Institute of Space Science and Technology after the launch of lunar satellite Chandrayaan-1 in 2008. Prime Minister Manmohan Singh approved the project on 3 August 2012,[28][29] after the Indian Space Research Organisation completed ₹125 crore (US$18 million) of required studies for the orbiter. It was not an easy assignment, feels Nandani but all have worked together to make it successful. Talking about Mission Mangalyan, Nandini says that it was a moment of not only for her and her team but for entire India.

He was also the Chairman at Launch Authorisation Board. The high-gain antenna system is based on a single 2.2-metre (7 ft 3 in) reflector illuminated by a feed at S-band. [26], On 23 November 2008, the first public acknowledgement of an uncrewed mission to Mars was announced by then-ISRO chairman G. Madhavan Nair. [101][102], On 24 March 2015, MOM completed its initial six-month mission in orbit around Mars. At 09:00:46 UT Sept. 23, 1999, the orbiter began its Mars orbit insertion burn as planned. It performed four course corrections: Dec. 21, 1998, and March, At 09:00:46 UT Sept. 23, 1999, the orbiter began its Mars orbit insertion. ISRO extended the mission by an additional six months; the spacecraft has 37 kg (82 lb) of propellant remaining and all five of its scientific instruments are working properly.

Mars Orbiter Mission: Meet the scientists team who made it possible. SK Shivakumar: Director of Isro Satellite Centre, Shivakumar joined Isro in 1976. Ritu Karidhal was the Deputy Operations Director of Navigation. Further, a specific search for methane in the Martian atmosphere will provide information about the possibility or the past existence of life on the planet. NASA's Mars Climate Orbiter was designed to study Mars from orbit and to serve as a communications relay for the Mars Polar Lander and Deep Space probes. [65] When testing the redundancies built-in for the propulsion system, the flow to the liquid engine stopped, with consequent reduction in incremental velocity. Moumita Dutta was the Project manager of the Mars Orbiter Mission.

[93] The 440-newton liquid apogee motor was test fired on 22 September at 09:00 UTC for 3.968 seconds, about 41 hours before actual orbit insertion.
