It took several attempts over 20 years for Indian scientists to develop
the titanium and composite materials engine, and the success of the launch
means that India would be self-reliant soon in sending heavy satellites to
deep space on its own.
It would take a couple of more attempts though to master the technology and
ensure the success of any future space missions.
So far, the Indian Space Research Organisation (ISRO) has been using European
Ariane (now part of Airbus Defence and Space) for launching its heavy satellites
although for satellites weighing up to 1,600 kgs, its indigenous Polar Satellite
Launch Vehicle (PSLV) proved to be a reliable workhorse. In fact, India has also
been in the international market and ISRO has launched small and medium satellites
for several countries.
But in Sunday’s launch, ISRO’s 414.75-tonne Geosynchronous Satellite Launch Vehicle
GSLV-D5 rocket propelled the 1,982-kg GSAT-14 in the designated orbit. A day later,
ISRO also carried a course correction.
According to ISRO, the three-stage GSLV (Mark I and II) is capable of placing 2,000
to 2,500 kg into Geosynchronous Transfer Orbit (GTO). The vehicle has a liftoff thrust of 6573 kn.
ISRO is now developing its Mark III version to propel satellites of up to 4500 to 5000 kg.
