What This Article Covers

1.ISRO's PSLV, with only 4 failures in 64 missions, suffered back-to-back anomalies in its third stage during the C61 (May 2025) and C62 (Jan 2026) missions, halting all launch activities.

2.A National Level Expert Committee headed by former Principal Scientific Adviser Prof. Vijayraghavan is reviewing the failures and is due to submit its report by June 2026, with ISRO confident of a bounce-back.

3.The launch delays have impacted the NavIC constellation (now down to 3 operational satellites), the maiden flight of the privately-built PSLV by HAL-L&T consortium, and the SSLV program which uses a PSLV-derived stage.

The Big Picture
Prelims · HighMains · Medium

Two consecutive failures of ISRO's reliable PSLV rocket in 2025 and 2026 have grounded key missions, delaying India's NavIC navigation system revival, the first private PSLV, and the SSLV program. A national expert committee, led by former PSA Prof. Vijayraghavan, is investigating the third-stage anomalies and is expected to submit its report by June 2026, paving the way for a resumption of launches.

ISRO Transfers SSLV, PSLV, LVM3 to Private Sector Under Indian Space Policy 2023

ISRO is transitioning from manufacturing operational launch vehicles to a pure R&D role, transferring SSLV, PSLV, and LVM3 production to private industry. This shift, mandated by the Indian Space Policy 2023, aims to expand India's share in the global space economy from less than 2% ($9 billion in 2026) to $40-45 billion over the next decade. The move opens up significant commercial opportunities for private players while preserving ISRO's expertise for strategic and scientific missions.
