ISRO Advancing Reusable Space Technology with Winged Orbital Re-Entry Vehicle (ORV)
In a significant step towards developing reusable launch vehicles, the Indian Space Research Organisation (ISRO) is working on a winged body Orbital Re-entry Vehicle (ORV). This advanced spacecraft will be launched into orbit using an ascent vehicle and later re-enter Earth's atmosphere, executing an autonomous runway landing. The ORV is a crucial component of India's long-term strategy for cost-effective and sustainable space exploration.
Successful Trials of Reusable Launch Vehicle (RLV-TD)
To validate the feasibility of this technology, ISRO has successfully conducted three Autonomous Runway Landing Experiments (RLV-LEX) using the Reusable Launch Vehicle-Technology Demonstrator (RLV-TD). These experiments have proven the robustness of onboard autonomous navigation, guidance, and control systems, laying the foundation for a fully operational ORV.
Advancements in Booster Stage Recovery
Apart from the ORV, ISRO is also focusing on developing Vertical Take-off and Vertical Landing (VTVL) technology for recovering and reusing booster stages. This innovation will significantly reduce launch costs by allowing multiple reuses of the spent boosters, similar to SpaceX's Falcon rockets.
Next-Generation Launch Vehicle (NGLV): A Step Towards Partial Reusability
The Indian government has approved the development of a Next Generation Launch Vehicle (NGLV), which will be a three-stage launch system. The first stage of this vehicle will be recoverable and reusable, making it India's first partially reusable space launch system. This development aligns with global efforts to create cost-efficient and sustainable space access.
Private Sector Involvement and Space Reforms
With the introduction of space sector reforms in June 2020, private companies are now allowed to provide end-to-end space services. The Indian National Space Promotion and Authorisation Centre (IN-SPACe) has been set up to facilitate and regulate private sector participation. This move is expected to boost India's space economy and enable collaborations in areas such as lunar mining and deep-space exploration.
Artificial Intelligence in Space Missions
Artificial Intelligence (AI) is playing an increasingly critical role in space missions. ISRO is integrating AI-based solutions in autonomous mission management, onboard data processing, and advanced space exploration. A recent AI-driven achievement includes an autonomous sensor-based actuator system that enables precise docking sequences using pattern recognition techniques.
Ensuring Responsible Use of Space
As a responsible space-faring nation, India actively contributes to space debris mitigation. The country follows internationally accepted guidelines set by agencies like the United Nations Committee on the Peaceful Uses of Outer Space (UN-COPUOS) and the Inter-Agency Space Debris Coordination Committee (IADC). The Indian Space Policy mandates strict adherence to these regulations, ensuring sustainable and safe space operations.
Looking Ahead: India’s Future in Space Exploration
India is setting ambitious goals, including achieving a successful lunar landing by 2040. This vision will involve extensive collaboration with private industries, academia, and international partners, driving India’s leadership in the global space domain.
With continuous advancements in reusable technology, artificial intelligence, and sustainable space practices, ISRO is paving the way for a more efficient and economically viable future in space exploration. The development of the Orbital Re-entry Vehicle (ORV) and Next-Gen Launch Vehicle (NGLV) marks a new era in India’s journey toward becoming a major player in the global space industry.
