	GSLV Launch Helps Move India Closer To Self-Reliance in Space (Site not responding. Last check: 2007-10-13)
		Krishnamurthi said the latest launch represents "a significant step forward in operationalizing the GSLV." The GSLV will be declared operational after one more successful flight, with the next mission scheduled for sometime next year, he said.
		In its present configuration, the three-stage GSLV is 49 meters tall and weighs 414 metric tons at liftoff.
		While the GSLV launch was a significant milestone in India’s bid for self-reliance in space, the commercial prospects for the vehicle are bleak due to its relatively low payload capacity and the depressed state of the commercial satellite market.

	Spaceflight Now \| Breaking News \| Second GSLV rocket launched
		The GSLV is the cornerstone in the Indian Space Research Organization's aspirations to have a "self-reliant" space program, where satellites are both built and launched from Indian soil.
		It is currently planned that the GSLV will have to chalk up at least three qualification flights before being entrusted to launch a fully operational satellite, and ISRO's plans for a lunar mission later this decade will require the use of a GSLV rocket.
		ISRO is also planning a third-generation version of the GSLV that could as much as double payload capacity in as little as six years using a new design, the Indian space program said in its most recent annual report.

	rediff.com Special: ISRO prepares to test GSLV again next year
		According to ISRO Chairman Dr K Kasturirangan, one of the four strap-on engines, which are the very first to be ignited in the launch, simply failed to generate enough thrust.
		Then, the second stage of the GSLV, which uses liquid propellants, namely UDMH as fuel and N2O4 as oxidisers in two compartments of an aluminium alloy tank separated by a thin metal sheet, ignites.
		Although the GSLV has been designed to ultimately help India launch her own INSAT communication satellites, this time it was to place only an experimental satellite called GSAT-1 in space.
