Isro's Mars Orbiter Mission
successfully placed in Mars transfer trajectory
>> Crossing a major milestone in the
country's space history, Isro's Mars Orbiter Mission on Sunday ventured out of
Earth's sphere of influence for the first time in an attempt to reach the red
planet's orbit.
>> The critical manoeuvre to place
the Mars orbiter spacecraft in the Mars transfer trajectory was successfully
carried out almost an hour past midnight.
>> During this manoeuvre, which began
at 00:49 hours, the spacecraft's 440 Newton liquid engine was fired for about
22 minutes providing a velocity increment of 648 metres/second to the
spacecraft.
>> "Following the completion of
this manoeuvre, the Earth orbiting phase of the spacecraft ended. The
spacecraft is now on a course to encounter Mars after a journey of about 10
months around the Sun," the Bangalore-headquartered Indian Space Research
Organisation said in a statement.
>> Isro performed the trans-Mars
injection, a "crucial event" intended for hurling its Mars orbiter
spacecraft into the planned orbit around the Sun, marking the first step
towards the 300 day voyage to reach the orbit of the red planet after crossing
roughly 680 million kilometres.
>> Isro has planned four mid-course
corrections in case of any deviation along its path to the Martian orbit.
>> The space agency is scheduled to
make four corrections in the course of the spacecraft's voyage to Mars before
it is expected to reach the orbit of the red planet in September 2014.
>> It had performed five
orbit-raising manoeuvres on its Mars Orbiter, raising the apogee (farthest point
from Earth) of the spacecraft to over 1.92 lakh kilometres, before it performed
the "mother of all slingshots".
>> The spacecraft is being
continuously 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, the space agency added.
>> Isro's PSLV C 25 successfully
injected the 1,350-kg 'Mangalyaan' Orbiter (Mars craft) into the orbit around
the earth some 44 minutes after a text book launch at 2.38 PM from the Satish
Dhawan Space Centre at Sriharikota on November 5, marking the successful
completion of the first stage of the Rs 450-crore mission.
