India's PSLV-C62 mission aims to reclaim its stellar launch record on January 12

India's Polar Satellite Launch Vehicle (PSLV) is set to return to flight on January 12, 2026, after a rare failure in mid-2025. The upcoming PSLV-C62 mission will carry the EOS-N1 Earth observation satellite and multiple co-passenger payloads, marking a critical test for the rocket's reliability. Known for its 94-95% success rate, the PSLV remains a cornerstone of India's space programme.

The PSLV-C62 mission follows a six-month grounding of the fleet after the PSLV-C61 failure in mid-2025. That mission suffered a propulsion anomaly in its solid-fuel stage, preventing the rocket from reaching orbit. ISRO conducted a thorough review and implemented corrective measures, including reinforced motor casings and improved nozzle control systems.

The new mission will deploy the EOS-N1 (also called EOS-Anvesha) satellite, designed for maritime surveillance. Alongside it, eight international co-passenger satellites from Thailand, Nepal, France, Spain, Brazil, and the UK will be launched. These payloads include AI-driven data processing, IoT applications, and in-orbit technology demonstrations.

The PSLV's four-stage design allows precise satellite placement, particularly into Sun-synchronous polar orbits. This capability has made it a trusted workhorse for both domestic and commercial launches. The January 12 flight from Sriharikota will test whether the recent upgrades have resolved the earlier issues.

The PSLV-C62 mission represents a key step in restoring confidence in India's most dependable launch vehicle. If successful, it will confirm the effectiveness of the corrective actions and reaffirm the PSLV's role in future missions. The rocket's return to flight also supports ongoing Earth observation and international collaboration efforts.
