INDIA
LAUNCHES MARS MISSION 'MANGALYAAN', PLACED
INTO EARTH ORBIT
India's maiden mission
to Mars was successfully launched on Tuesday with its polar rocket placing the
Mars spacecraft precisely into an intended Earth orbit in its first-ever
historic inter-planetary odyssey in a bid to join a select band of nations.
In a "new and complex mission design",
ISRO's PSLV C 25 successfully injected the 1,350-kg 'Mangalyaan' Orbiter ('Mars
craft' in Hindi) into the orbit around Earth some 44 minutes after a text book
launch at 2.38 PM from the Satish Dhawan Space Centre, marking the successful
completion of the first stage of the Rs 450 crore mission.
Entering a new frontier in space technology, Indian Space Research
Organisation(ISRO)'s mission is aimed at establishing India's capability to
reach the Red Planet and would focus on looking for presence of methane, an
indicator of life there.
"The PSLV C25 vehicle has placed the Mars Orbiter spacecraft very
precisely into an elliptical orbit around Earth," ISRO chief K
Radhakrishnan said after the launch.
This is the 25th flight of the Polar Satellite Launch Vehicle(PSLV) and
"it has been a new and complex mission design to ensure that we would be
able to move the MARS Orbiter spacecraft from the orbit of Earth to the orbit
of MARS with minimum energy," he said from Mission Control Room.
After going around Earth for 25 days in an elliptical orbit (perigee of 250 km
and apogee of 23,500 km), the golden coloured probe, the size of a small car,
would embark on a 10-month long voyage to Mars around 12.42 AM on December 1.
It is expected to reach the Red Planet's orbit by September 24 next and go
around in an elliptical orbit (periapsis of 366 km and apo-apsis of 80,000 km).
"I am happy to say the spacecraft is in good health. It has done a task
what had to be done," a visibly relieved and happy Radhakrishnan told
reporters.
The rocket injected the satellite into Earth's orbit over South America, which
was captured by ISRO's sea-borne terminals on board Shipping Corporation of
India's vessels SCI Nalanda and SCI Yamuna in the South Pacific Ocean.
There was a data break of over 10 minutes as expected after burn-out of the
third stage and the Mission Control Centre got signals on ignition of the
fourth stage.
"The biggest challenge will be precisely navigating the spacecraft to
Mars," said Radhakrishnan, adding, "We will know if we pass our
examination on Sept. 24, 2014."
The robotic satellite, which is undertaking the over 200-million-km long
journey to Mars, is equipped with five instruments, including a sensor to track
methane or marsh gas - a possible sign of life - on Mars.
If all goes well and the satellite orbits the Red Planet, ISRO will become the
fourth in the world after those of the US, Russia and Europe to undertake a
successful Mars mission. The Mars missions of China and Japan have failed.
