Based on principle of Perform, Achieve, Trade.

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 services.

vi) Technology could be used for defence and other strategic capabilities.

vii) Reduction in emissions due to low resource utilisation.
