b. Reusable Satellite Launch Vehicle Technology Demonstrator
c. Relaunchable Satellite Long Vehicle Technology Demonstrator
d. None of the above

ANSWER: Reusable Satellite Launch Vehicle Technology Demonstrator
 
A milestone in indigenous satellite program, Indian Space Research Organisation ( ISRO ) successfully launched the Re-usable Satellite Launch Vehicle- Technology Demonstrator (RLV-TD) from Sriharikota.
  • It demonstrated the success of the hypersonic flight, re-entry aero thermodynamics, autonomous mission management and hot structures for thermal protection
  • Nearly 80% of the rocket cost is towards engines and structure. If the engines and the structure can be recovered and re-used, there could be substantial reduction in cost to launch payloads in space.
  • Further there will be tests on the RLV with Air breathing propulsion system (ABPS) which uses atmospheric air as oxidiser for combustion with vehicle fuel to propel the rocket and it can bring down space travel cost by minimum one tenth
  • It is developed relatively at a low cost compared to other countries. Current RLV-TD incurs a project cost of Rs 95 crore.
