After an eventful year capped by the mission to moon, ISRO scientists are now developing the next generation launch vehicle to cut by half the cost of putting satellites in orbit. The new year will see a series of tests in the development of the Geosynchronous Satellite Launch Vehicle (GSLV) Mark III, which is expected to take to the skies in 2010-11.
The new rocket, which can put a four-tonne satellite in orbit, will help Antrix Corporation, ISRO’s commercial arm, to offer cheapest space launches in the niche market. The regular GSLV can put 2.2 tonne satellites in orbit. “The new year will see solid booster testing for the Mark III, followed by the liquid stage after which we will test the cryogenic engine stage,” K Radhakrishnan, director, Vikram Sarabhai Space Centre told PTI.
“We are planning to have flight testing during 2010-11,” he said. Mr Radhakrishnan said, ISRO will be able to pack more transponders in one-space flight. “This makes it a cost effective solution and will give us a niche in the world in launching four tonne satellites,” he said.
The GSLV Mark III will also help ISRO put more Indians in space at one go. As per the current plans, the agency plans to send two Indians on a week-long space sojourn in 2015. “The regular GSLV will be used for the human spaceflight. In case we use Mark III, we can send three persons instead of two,” said Mr Radhakrishnan.
With GSLV Mark III, ISRO can think of sending more meaningful probes to Mars and other inter-planetary missions, which it plans to undertake in the future. ISRO has announced that it will launch a mission to Mars in 2013 using the regular GSLV which is capable of carrying a 500-kg payload to the Red planet.
“For the Mars expedition, you can use a PSLV or the regular GSLV or even the Mark III but if you have to have a meaningful mission the instrument has to be large enough to carry out many experiments,” said Mr Radhakrishnan.
He said the agency also plans to build in more reliability into the new rocket to make is usable for undertaking human space mission. According to ISRO chairman G Madhavan Nair, Antrix Corporation made Rs 1,000 crore this year by launching and building satellites for foreign firms and institutions. “We hope to grow at the rate of 20% every year,” Mr Nair said.
A major chunk of it came through the development of W2M communications satellite ISRO built for Eutelsat. The 3.5-tonne satellite was launched by Ariane rocket from Kourou in French Guiana. ISRO crossed key milestones last year with the successful launch of Chandrayaan-I in October and earlier in April, when it put into orbit 10 satellites on a single Polar Satellite Launch Vehicle (PSLV), becoming the first country to achieve the feat. Of the 10 satellites, two — Cartosat-2 and Indian Mini Satellite — were developed indigenously, while eight nano satellites belonged to international customers.
