Context: Chennai-based spacetech startup Agnikul Cosmos has announced that its upcoming rockets will be fully reusable, ensuring no component is discarded. This aligns with the International Astronautical Congress (IAC) 2025 theme: “Sustainable Space: Resilient Earth.”
Key Highlights
- Agnikul’s Vision: To offer globally competitive small-satellite launch services with complete reusability.
- Technology Achievements:
- Successfully tested 3D-printed sub-orbital rocket Agnibaan SOrTeD (2024).
- Plans for orbital launches with reusability.
- Support Mechanism: Backed by IN-SPACe, which provides policy and technical support.
- Focus Areas: Cost efficiency, scalability, and compliance with space debris mitigation.

Reusable Launch Vehicles (RLVs)
- Definition: A rocket system that can be launched, recovered, and reused multiple times. Unlike expendable rockets, RLVs ensure controlled re-entry and reduce space junk.
- Advantages:
- Cuts down launch costs.
- Minimizes space debris, mitigating risks like the Kessler Syndrome (cascading orbital collisions).
- Enhances sustainability of global space missions.
India’s Efforts in RLVs
- ISRO Milestones:
- RLV-TD HEX-01 (2016): Demonstrator flight for re-entry.
- RLV LEX Series (2024): Autonomous landing tests.
- PUSHPAK Mission: Ongoing experimental reusability projects.
- Agnikul’s Initiative: Complements ISRO’s programmes by targeting commercial small-satellite launches.
Global Context
- SpaceX (USA): Falcon 9, Falcon Heavy — world leaders in reusable rockets.
- China: Long March 8 with partial reusability.
- India’s Entry: Aims to position itself as a sustainable, affordable, and competitive space launch hub.
Significance
- Strengthens India’s Atmanirbhar Bharat vision in space technology.
- Encourages startups–ISRO collaboration, expanding the private space ecosystem.
- Demonstrates India’s commitment to sustainable space exploration and debris-free orbits.
