Explanation: The RLV -TD that ISRO flew on Monday morning at Sriharikota is the first step in an Indian effort to develop a Two Stage To Orbit (TSTO) fully reusable vehicle. The hypersonic flight experiment (HEX) on Monday will be followed by a landing experiment (LEX), a return flight experiment (REX) and a scramjet propulsion experiment (SPEX) in the coming days. Though manned space flight is the ultimate goal of RLVs the major advantage of development of an RLV is the reduction in cost of space launches and space travel itself.
