India set to put Mars Orbiter Mission (MOM) in Mars orbit
The Isro scientists on Sunday started the process of 'waking up' the engine of the Mars Orbiter Mission (MOM) spacecraft for a four-second test on September 22.
The scientists are planning to put the MOM to its ultimate test after three days when they will fire it for 24 minutes to slow down the MOM and inject it into the Martial orbit. If the scientists succeed in achieving this, India will become the first country to do so on debut.
The US, Russia and the European Space Agency had got it right after several attempts.
MOM is currently hurtling at a speed of 82,000kmph and it has been idling for about 300 days since leaving the orbit of the earth on November 30, 2013.
"We have to see if the engine is in shape, hence the test," said Isro chairman K Radhakrishnan. "It will also serve as a trajectory correction which will take MOM to a 515km arrival spot from Mars."
On Sunday, a bundle of commands were sent by scientists at Isro Telemetry Tracking and Command Network in Bangalore to test-fire the liquid apogee motor (LAM) engine for four seconds.
MOM is scheduled to enter the Martian orbit two days after the US orbiter MAVEN. Making use of ingenuous sling-shot approach, India has succeededin sending the orbiter to Mars at Rs450 crore, which is 10 times less than the cost of the Nasa mission.

The Mars Orbiter Mission (MOM), informally called Mangalyaan (Sanskrit for "Mars-Craft"), is a Mars orbiter launched into Earth orbit on 5 November 2013 by the Indian Space Research Organisation (ISRO). It is expected to enter orbit around Mars on 24 September 2014. The mission is a "technology demonstrator" project aiming to develop the technologies required for design, planning, management, and operations of an interplanetary mission
The Mars Orbiter Mission probe lifted-off from the First Launch Pad at Satish Dhawan Space Centre SHAR, Sriharikota, Andhra Pradesh, using a Polar Satellite Launch Vehicle (PSLV) rocket C25 at 09:08 UTC (14:38 IST) on 5 November 2013.[13] The launch window was approximately 20 days long and started on 28 October 2013. The MOM probe spent about a month in Earth orbit, where it made a series of seven altitude-raising orbital manoeuvres before trans-Mars injection on 30 November 2013 (UTC)
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 the European Space Agency.[15] The spacecraft is currently being monitored from the Spacecraft Control Centre at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bangalore with support from Indian Deep Space Network (IDSN) antennae at Byalalu

History Mars Orbiter Mission
The MOM mission concept began with a feasibility study in 2010, after the launch of lunar satellite Chandrayaan-1 in 2008. The government of India approved the project on 3 August 2012,[17] after the Indian Space Research Organisation completed INR1.25 billion (US$21 million) of required studies for the orbiter. The total project cost may be up to INR4.54 billion (US$75 million). The satellite costs INR1.53 billion (US$25 million) and the rest of the budget has been attributed to ground stations and relay upgrades that will be used for other ISRO projects.
The space agency had initially planned the launch on 28 October 2013 but was postponed to 5 November 2013 following the delay in ISRO's spacecraft tracking ships to take up pre-determined positions due to poor weather in the Pacific Ocean.Launch opportunities for a fuel-saving Hohmann transfer orbit occur about every 26 months, in this case, 2016 and 2018. 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. The mounting of the five scientific instruments was completed at ISRO Satellite Centre, Bangalore, and the finished spacecraft was shipped to Sriharikota on 2 October 2013 for integration to the PSLV-XL launch vehicle The satellite's development was fast-tracked and completed in a record 15 months Despite the US federal government shutdown, NASA reaffirmed on 5 October 2013 it would provide communications and navigation support to the mission.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.
The ISRO plans to send a follow up mission in the 2017-2020 timeframe with a greater scientific payload.
