Cryogenic Pioneer N. Jayan to Head ISRO’s Propulsion Centre

ISRO has appointed eminent aerospace engineer N. Jayan, architect of the CE20 cryogenic engine, as the new Director of the Liquid Propulsion Systems Centre (LPSC), a critical hub for India’s advanced propulsion systems. He will assume charge on July 1, 2026, marking a major leadership transition in ISRO’s propulsion program.

N. Jayan has served as Project Director, overseeing the indigenous development of India’s cryogenic propulsion technology, which was a breakthrough in self-reliance for space transportation. He led the team that successfully developed the CE20 engine powering LVM3 (GSLV Mk III), enabling India’s heaviest rocket to launch complex satellites and crewed missions.

As Project Director, he spearheaded ISRO’s future heavy-lift rocket program, positioning India for deep-space exploration and commercial competitiveness.

Today, CE20 powers the Cryogenic Upper Stage (C25) of India’s heaviest rocket LVM3, enabling payloads up to 4 tonnes to GTO and 10 tonnes to LEO (Low Earth Orbit), enabling payloads up to 4 tonnes to GTO and 10 tonnes to LEO.

Key Highlights of the Appointment

• N. Jayan: Senior scientist and propulsion expert, pivotal in developing the CE20 cryogenic engine that powers the LVM3 (formerly GSLV Mk III).
• New Role: Director of Liquid Propulsion Systems Centre (LPSC), Thiruvananthapuram.
• Effective Date: July 1, 2026.
• Career Milestones: Associate Director, LPSC; Project Director, Cryogenic Stage Project; Project Director, Next Generation Launch Vehicle (NGLV) at VSSC.
• Awards: Recipient of the Rashtriya Vigyan Puraskar (2025), India’s highest science honor.

Significance for ISRO

• Strengthening Propulsion Leadership: LPSC is responsible for liquid, cryogenic, and advanced propulsion systems—the backbone of India’s launch vehicles.
• Indigenous Capability: Jayan’s leadership in CE20 development enhanced India’s self-reliance in cryogenic technology, enabling complex missions including human spaceflight.
• Future Roadmap: His role in the NGLV project positions ISRO to advance next-generation heavy-lift capabilities, crucial for deep-space exploration and commercial launches.
