ISRO restarts PSLV space launches in May 2026 after technical delays

ISRO is starting its rocket launches again this May after a six-month break. This is a big step to fix the problems seen in the last two missions.

The Indian Space Research Organisation (ISRO) is preparing to resume orbital launch operations in May 2026. This restart follows a six-month period of inactivity triggered by consecutive anomalies in the Polar Satellite Launch Vehicle (PSLV) program, specifically within the vehicle's third stage during missions PSLV-C61 and PSLV-C62.

The agency has convened a National Level Expert Committee to investigate technical failures, marking a pivot toward systemic industrial review as it attempts to reclaim operational momentum.

Technical Anomalies and Operational Impact

The PSLV, historically considered the agency’s "workhorse," has faced severe scrutiny following the back-to-back trajectory deviations of its latest missions. While the LVM-3 continues to maintain a faultless flight record, the PSLV's technical lapses have created a bottleneck for several strategic and commercial objectives:

  • NavIC Navigation: Indigenous satellite constellation expansion is currently stalled.

  • SSLV Development: The Small Satellite Launch Vehicle (SSLV), which utilizes technology derived from the PSLV's third stage, has been impacted by the ongoing forensic probe.

  • Private Integration: Multiple private missions, including the inaugural flight of privately manufactured PSLV components, have faced significant scheduling shifts.

Industry Re-alignment and Private Sector Growth

While ISRO recalibrates its internal engineering, the Indian Space Sector is seeing an increase in decentralized activity through IN-SPACe. Funding and collaborative agreements are moving forward despite the agency’s primary launch delays:

Under the Technology Adoption Fund (TAF) scheme, entities like Astrobase Space Technologies, SatSure Analytics, and TM2SPACE have been selected for funding, signaling a shift toward diversifying the manufacturing base to mitigate reliance on centralized, single-point-of-failure infrastructure.

Institutional Context: Transparency vs. Strategy

The decision to proceed with the PSLV-C62 launch prior to the full public disclosure of the PSLV-C61 Failure Analysis Committee report drew criticism regarding institutional transparency. The current restart plan in May represents an attempt to reconcile these demands for accountability with the necessity of maintaining a viable Space Policy roadmap.

The agency now faces the challenge of managing a dual-track strategy: stabilizing the legacy PSLV architecture while simultaneously accelerating the transfer of hardware manufacturing to private industry partners to broaden the scope of India's Space Economy.

Frequently Asked Questions

Q: Why did ISRO stop launching PSLV rockets for six months?
ISRO stopped launches because of technical problems during the PSLV-C61 and PSLV-C62 missions. A special committee is now checking the rockets to make sure they are safe to fly again.
Q: When will ISRO start launching rockets again?
ISRO plans to start its launch operations again in May 2026. This restart follows a long period of testing and safety reviews to fix past errors.
Q: How do the PSLV launch delays affect private space companies in India?
The delays have pushed back schedules for private missions and new satellite projects. However, private companies are still working with the government through new funding programs to grow the space industry.
Q: What is the goal of the new ISRO expert committee?
The National Level Expert Committee is investigating why the rockets failed during recent flights. Their goal is to fix the technical problems and make sure future missions are successful.
