The blandly-named Geosynchronous Satellite Launch Vehicle (GSLV) is the most technologically challenging project so far undertaken by the Indian space programme and carries the hopes and aspirations of thousands of scientists, engineers and industrialists.
The three-stage GSLV is due to blast off from the Sriharikota launch site in the southern state of Andhra Pradesh during a four-hour window period beginning at around 4:00pm (1030 GMT) on Wednesday.
Previous launch vehicles, with satellite payloads ranging from 40 kilograms to one tonne have failed to place their satellites in the correct orbits, placing even more pressure on the performance of the GSLV.

Launching a massive 300-tonne plus 40-metre high rocket tens of thousands of kilometres into space, inject a satellite with such precision that it will go around the earth at the same rate as the earth, and hence stay overhead, is no mean task.
Currently, such satellites that provide transponders for communications and TV channels, are launched by Arianspace, the European consortium, or the Russians.

 Allen Steele - House Testimony
At present the market for launch services is still limited, yet in the coming years we can expect to see the commercial space industry to experience exponential growth as the demand for satellite technology increases.
A half-dozen small companies are poised to build and launch a new generation of passenger-rated spacecraft which are less expensive to maintain and operate than the present space shuttle fleet, yet all are hindered by lack of private investment and the burden of government overregulation.
This was demonstrated during the early 1980's, when the demands of the satellite launch industry contributed in part to the circumstances which led to the Challenger disaster; the Reagan Administration responded by barring commercial payloads from the space shuttle fleet.

 rediff.com: GSLV relaunch likely in May
The aborted Geosynchronous Satellite Launch Vehicle is likely to be re-launched ''sometime in May'', Union Minister for Science and Technology Murli Manohar Joshi said on Friday.
Zeroing in on the defect, which resulted in the GSLV launch mission being aborted a second before lift-off, required immense amount of data to be studied, he said, adding there would also be the problem of deciding a fixed launch window.
Deciding a date for a GSLV launch had to be preceded by assessing "a whole lot of factors,' including weather and climatic changes, the spokesman said.

The much-awaited test flight, using the indigenous Geosynchronous Satellite Launch Vehicle (GSLV) technology, "failed" to take-off due to certain last second hitches in one of the four strap-on engines, forcing ISRO authorities to "cancel" Wednesday’s mission.
It was the automatic control that gave the command to "abort" Wednesday's mission when one of the four strap-ons did not burn enough to give the "required thrust" for the spacecraft to lift off.
Asked about the damage suffered to the launch vehicle, he said only the insulation of the strap-on engines had burnt off.
