ISRO is gearing up for todays rocket launch and Here are some key facts about Isros Mars mission: 1. This is the first time the national space agency is aspiring to send a mission to study a celestial body outside Earths sphere of influence. 2. Indias Mars Orbiter is expected to reach the red planets orbit by September 2014 and look for the presence of methane, an indicator of life there. 3. Isro has put in place an extensive network of stations worldwide to track the Mars Orbiter Mission after launch from the first launch pad here at 2.38pm. 4. Unlike other PSLV missions, PSLV C25 will take more than 40 minutes to inject the Mars Orbiter into Earths orbit as it has a long coasting phase (1,700 seconds) for the launch and has to achieve an argument of perigee of 276.4 degrees. 5. The vehicle trajectory will be tracked by monitoring stations at the Space Centre here, Indian Deep Station Network at Byalulu near Bangalore and Down Range Station at Port Blair in India and also from Biak in Indonesia and Brunei. 6. Two sea-borne terminals equipped with a 4.6 metre antenna and a 1.8 metre antenna on board Shipping Corporation of Indias SCI Nalanda and SCI Yamuna (some 2500 km between them) in South Pacific Ocean will track the vehicle as it injects the Mars Orbiter mission into Earths orbit. 7. Once injected into orbit by the launch vehicle, the spacecraft trajectory post separation would be tracked from NASAs Jet Propulsion Laboratory facilities at Goldstone (U.S), Madrid (Spain) and Canberra (Australia). 8. The Mars Orbiter carries five scientific instruments to study the red planet - 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). 9. While LAP and MSM would help in atmospheric studies,MENCA would focus on studying particle environment.MCC and TIS would contribute to studying the surface imaging of the red planet. 10. After having received 33 ideas for instruments to be flown to Mars, Isro shortlisted nine, of which the Advisory Committee of Space Sciences headed by Prof U R Rao finalised five instruments as only these were mature enough for the flight. 11. The 1,337 kg Mars Orbiter with 852 kg fuel and 15 kg of scientific instruments is expected to reach Mars orbit on September 14, 2014. 12. Though there have been 51 missions to the red planet by some countries, only 21 have been considered successful, according to NASA.
