As a consequence of the decline of budget allocation for flights year by year, the ideas of reusability and cost-effectiveness in launch vehicles are becoming more and more important. Particularly the sounding rockets launch operation has many potentials for many more flights. Basic rocket configuration is enhanced with the wings, landing gear, flight controls and guidance systems, the rocket can be made to glide and land back at the launch site or at a specific recovery site. The concept behind reusable rockets is to reclaim the ultra-expensive rocket boosters used for launching rockets, and afterwards to refuel and reuse them for rocket flight.

The Reusable Sounding Rocket is a fully re-usable sub-orbital sounding rocket that takes-off from the launch site and after placement of payload in the orbit it will land vertically on the same launch site by controlling it from the control center. one can make repeated use of instruments, recover samples, have a big data storage onboard. The Reusable Sounding Rocket can be launched daily and its target cost for operation is 1/10 of the existing sounding rocket.

For Reusable Rockets, the main technical difference is in propulsion system. Existing Sounding Rockets are made up solid propulsion, where it cannot be controlled once it is ignited. But in the Reusable Sounding Rocket, the propulsion system is clustered LOX/LH2 engines with full-time abort capability despite the one engine fail. To realize the reusable sounding rocket, the main propulsion system should have advanced features of high reliability, reusability, maintainability, and survivability.
