How ISRO’s test flight of RLV-TD will bring down cost of satellite launches

Indian Space Research Organisation (ISRO) will carry out a test flight of Reusable Launch Vehicle – Technology Demonstrator (RLV-TD) by second quarter of 2015.

ISRO has taken steps to develop next generation launch vehicle GSLV MkIII, capable of launching 4 ton class communication satellites to Geo-synchronous Transfer Orbit, which would bring down the cost of satellite launches.

“Development of Reusable Launch Vehicles is a technical challenge and it involves development of many cutting edge technologies. The magnitude of cost reduction depends on development and realization of fully reusable launch vehicle and its degree of reusability, “ MoS Dr Dr Jitendra Singh said in a reply to unstarred question in the Lok Sabha today.
