GSLV launch on April 15, PSLV on May 5

India's GSLV rocket, powered by home-made cryogenic engine for the first time, would be launched on April 15 from Sriharikota to place into orbit GSAT-4 experimental satellite.

The Indian Space Research Organisation (Isro) also fixed May 5 as the date for the launch of the Cartosat-2B by Polar Satellite Launch Vehicle (PSLV).

The mission readiness review conducted by ISRO at Sriharikota yesterday finalised the dates, and gave the go-ahead for the two launches, sources in the space agency told PTI in Bangalore.

The GSLV would be powered by home-made cryogenic engine for the first time. Previous GSLV flights were fitted with Russian engines.

Besides the Cartosat-2B, the PSLV would also have on board an Algerian satellite and some small and nano satellites, Isro sources said.
