Indian heavy lift satellite launch vehicle to blast off on Sunday

NEW DELHI, Jan. 5 (Xinhua) -- India is set to launch at 16:18 P. M. local time Sunday its heavy lift Geo-synchronous Satellite Launch Vehicle (GSLV) using indigenous cryogenic fuel technology, after two previous failures.

Indian Space Research Organization (ISRO) will attempt to launch a 1,982 kg Indian communication satellite GSAT 14 aboard its new and improved version of the indigenous GSLV called the GSLV D5.

This launch is crucial for the launching of manned missions into space, said ISRO officials.

The scheduled launch of the GSLV D5 will be ISRO's second attempt at deploying indigenously developed cryogenic upper stage fuel technology for its heavy lift rockets, after the first attempt on April 15, 2010 ended with the cryogenic third stage of the GSLV failing to fire. A second attempt on Aug. 19, 2013 was aborted as well.

The cryogenic technology which enables rockets to place satellites weighing more than 2,000 kg in geo-synchronous orbits in space is known to be available to only five countries in the world -- the United States, Russia, Japan, France and China.

Indian space scientists have been working on cryogenic fuel technology for nearly 20 years, according to Indian Express daily.

ISRO had tried to source the technology in the 1990s from the United States but was denied the "strategic technology" in the aftermath of the nuclear tests in 1998. ISRO subsequently worked with seven cryo engines provided by Russia for early development of the GSLV program while working in parallel on its own cryogenic stage for the rocket, according to the newspaper.

GSLV launches with Russian cryo stages have been a mixed bag for ISRO with two fully successful flights and two partially successful flights out of the seven attempted.
