Body · points

Principles involved

  1. 2-staged project: Subsequent return POST deployment
  2. Reducing friction upon reentry: 60° angle maintained
  3. Improving cost benefit Ratio & tooth to tail ratio of ISRO.
  4. R&D promotion, cutting Edge technology, etc

Significance & Benefits:

  1. Would significantly reduce mission cost and provide
  2. Cost Efficiency to India's space sector => Investments & contracts ↗.
  3. Induce pvt. sector investment (like Space X's Falcon, etc.)
  4. Enhance satellite launches: upstream & Downstream services to boost Agri, Disaster mgmt, etc
  5. Reduce space Debris, material reusability, innovation & R-D.
