Introduction :
India’s first interplanetary probe, the Mars Orbiter Mission, has left
home on the first leg of a voyage of scientific discovery. Once again,
the Polar Satellite Launch Vehicle developed by the Indian Space
Research Organisation performed its task with impeccable ease.
Facts :
- ISRO’s next focus is Chandrayaan 2 and GSLV
- Mars orbiter mission would continue till 2015.
- India's Mars orbiter will travel 300 days through space to reach the orbit of Mars
Journey :
A long and difficult trek now lies ahead of the spacecraft. It will
circle Earth for the rest of this month, repeatedly firing an onboard
liquid-propellant engine to gain velocity. Shortly after
midnight on November 30, the engine will fire again to put it on course for the Red Planet, a journey of 680 million kilometres that will take almost 300 days to complete.

Comparison :
Only the Soviet Union, the U.S. and Europe have succeeded in getting
spacecraft to the fourth planet from the Sun. Japan, a nation whose
space programme began well before India’s and which has rich experience
in a variety of space missions, ran into problems that ultimately
crippled its maiden Martian venture launched in 1998. The Nozomi
spacecraft’s propulsion system malfunctioned and then powerful solar
flares seriously damaged key components. The probe ended up shooting
past Mars, instead of going into orbit around it. China tried to hitch a
ride for its Yinghuo-1 spacecraft on Russia’s Phobos-Grunt. But the
latter was unable to leave Earth orbit and burnt up as it fell to the
ground early last year in Nov 2011
Critisism & Defence :
Looking at the country’s state of abject
poverty, malnutrition and underdevelopment, some have questioned the
profligacy of India heading to the Red Planet on a mission that costs
Rs.450 crore.
Later this month, India will send a 1,350-kg unmanned satellite aptly
called “Mangalyaan” which means “Mars craft” made by a team of 500
scientists from ISRO in a record 15 months, the shortest time frame for
any of the over 100 space missions India has ever undertaken.
In a manner that has similarities with the clarion call given by John F.
Kennedy in 1961 that Americans will land on the moon, Prime Minister
Manmohan Singh, in his Independence Day speech on August 15, 2012,
described the Mangalyaan mission as a “huge step for us,” proclaiming
that “our craft will soon go to Mars and collect important scientific
information.” Since 1960, about 45 missions to Mars have been
launched with a third having ended in disaster and no single nation
succeeding in its maiden venture.
Science and Cyclones
To some diehard critics of the Indian Mars mission, the recent Phailin
cyclone in Odisha should be an eye-opener, where the loss of life was a
mere 44. In comparison, about 10,000 people lost their lives in the
supercyclone of 1999 and 3,00,000 people died in the Sunderbans and
Bangladesh in the Bhola Cyclone of 1970. The crucial difference now is
that India today had as many as half-a-dozen satellites, all made by
ISRO, keeping a constant vigil on the cyclone as it roared over the Bay
of Bengal, while the string of Doppler Radars that line the coast along
the Bay of Bengal also helped.
