Principles behind the working of RLV:
Majority of two types:
In this the launch vehicle after it has successfully deployed the satellite is landed back on the earth to be used for next launches.

Significance and Potential Benefits:
(i) Reduce the cost of launch - upto 80% as per ISRO estimates
(ii) More efficient use of resources
(iii) Reduction in space debris
(iv) Faster launches to space by reusing the launch vehicles
(v) Increased utilisation of space-based servicing
(vi) Technology could be used for defence and other strategic capabilities
(vii) Reduction in emissions due to low resource utilisation
Challenge: Development of technology - heat shield, autonomous and precise navigation, advanced material, software
High upfront cost.
ISRO and private companies such as SPACEX are working on the technology. This will help in several future space launches aiding in climate change mitigation, disaster management and monitoring services.
Conclusion
ISRO and private companies such as SPACEX are working on the technology. This will help in several future space launches aiding in climate change mitigation, disaster management and monitoring services.
