Introduction: A Nuclear Vision for Viksit Bharat@2047 As India marches toward its ambitious goal of becoming a developed nation by 2047, energy security stands as a pivotal pillar in the vision of Viksit Bharat . Amid the global climate crisis and rising energy demands, nuclear power has re-emerged as a compelling solution. India’s commitment to achieving 100 GW of nuclear power capacity by 2047 is both visionary and necessary—but achieving this requires a strategic shift in policy, participation, and international cooperation. While India’s nuclear energy sector has traditionally been a tightly controlled domain under government monopoly—primarily led by the Department of Atomic Energy (DAE) and Nuclear Power Corporation of India Limited (NPCIL) —it is now imperative to welcome private sector investments and foreign partnerships.

What is a Semi-Cryogenic Engine?

A semi-cryogenic engine is a type of rocket propulsion system that uses a combination of liquid oxygen (LOX) as an oxidizer and kerosene-based fuel. Unlike fully cryogenic engines that use both LOX and liquid hydrogen (LH2), semi-cryogenic engines are more cost-effective and offer higher thrust, making them ideal for heavy-lift launch vehicles.

Key Advantages of Semi-Cryogenic Engines

  1. Higher Thrust: Provides greater lifting capacity for large payloads.
  2. Cost-Effective: Uses kerosene instead of expensive liquid hydrogen.
  3. Storage and Handling: Easier to manage compared to cryogenic propellants.
  4. Reusability Potential: Can be adapted for future reusable launch systems.

Details of the Recent Test

The semi-cryogenic engine test was conducted at ISRO's propulsion test facility in [location]. The engine, developed as part of the Semi-Cryogenic Propulsion System (SCPS) program, successfully fired for [duration] seconds, demonstrating its operational efficiency and performance parameters.

Objectives of the Test

  • Validate the engine’s fuel combustion efficiency.
  • Assess its thrust generation capabilities.
  • Ensure system reliability for long-duration operations.
  • Optimize engine cooling and fuel mixture ratio.

Importance of Semi-Cryogenic Technology in Future ISRO Missions

ISRO's semi-cryogenic engines are being developed for the upcoming Unified Launch Vehicle (ULV) program, which aims to replace existing launch vehicles like the PSLV and GSLV series. These advanced engines will significantly enhance India’s ability to conduct:

  • Heavy Satellite Launches: Deployment of large communication and defense satellites.
  • Manned Space Missions: Support for Gaganyaan and beyond.
  • Deep Space Exploration: Boosting missions to the Moon, Mars, and beyond.
  • Reusable Launch Vehicles: Future adaptation for cost-efficient, reusable rockets.

Global Comparison: How ISRO’s Semi-Cryogenic Engine Stacks Up

ISRO joins an elite group of space agencies working on semi-cryogenic technology, including NASA, Roscosmos, and SpaceX. Countries like the USA and Russia have long relied on semi-cryogenic propulsion for their heavy-lift rockets, such as:

  • Falcon 9 (SpaceX): Uses RP-1 (kerosene) and LOX.
  • Soyuz Rocket (Russia): Semi-cryogenic engines for reliable space travel.
  • Delta IV (USA): Employs similar propulsion technology.

ISRO’s semi-cryogenic engine is expected to rival these global counterparts, strengthening India’s independent space launch capabilities.

Future of India’s Space Exploration with Semi-Cryogenic Engines

The successful test of the semi-cryogenic engine marks a crucial step in ISRO’s roadmap for future missions. Here’s what’s next:

  • Integrated Stage Testing: ISRO will conduct full-stage trials to validate the engine within a complete launch vehicle configuration.
  • First Launch with ULV: The new engine is expected to power the next generation of launch vehicles by [expected timeline].
  • Human Spaceflight Integration: Potential use in future versions of Gaganyaan missions.
  • Commercial Launch Market: Strengthening ISRO’s role in global satellite launch .

Conclusion

ISRO’s successful semi-cryogenic engine test is a game-changer in India’s space program. With enhanced thrust, cost-efficiency, and global competitiveness, this propulsion system will revolutionize future space exploration and heavy-lift missions. As India continues to make strides in space technology, the world eagerly awaits the next breakthrough from ISRO.

IN-SPACe CANSAT & Model Rocketry India Student Competition 2024–25: A Giant Leap for Student Innovation

By
In a remarkable step towards strengthening India’s STEM education framework, the Astronautical Society of India (ASI), in collaboration with the Indian Space Research Organisation (ISRO) and the Indian National Space Promotion and Authorization Center (IN-SPACe), has launched the IN-SPACe CANSAT and Model Rocketry India Student Competition 2024–25 . This unique competition is crafted for undergraduate students across India, providing them with an opportunity to engage in experiential learning through the design, fabrication, and launch of CANSATs—can-sized satellites—using model rocketry platforms. The event held on June 14, 2025 , in Tamkuhi Raj, Kushinagar, Uttar Pradesh , was not a full-fledged rocket launch carrying an actual payload. Instead, it served as a critical site and systems validation test in preparation for the upcoming national student competition. This test focused on ensuring the readiness of launch site infrastructure, safety protocols, telemetry systems, and track...
