PSLV Launch Setback Raises Questions as ISRO Reviews Mission Performance

India’s space programme faced another challenging moment as the Polar Satellite Launch Vehicle (PSLV), long regarded as the backbone of the country’s launch capabilities, encountered issues during its latest mission in January 2026. The development follows an earlier setback in May 2025, making this the second time in less than a year that a PSLV mission has not achieved its intended objectives.

The most recent mission, designated PSLV-C62, was ISRO’s first launch of 2026 and was expected to mark a return to normal operations after the previous year’s anomaly. However, the mission did not progress as planned, resulting in the loss of its primary satellite payload along with several co-passenger satellites. Officials have confirmed that the issue occurred during the later phase of the flight, prompting a detailed technical review.

What Happened During the Mission

According to the Indian Space Research Organisation (ISRO), the launch vehicle performed as expected during the initial phases of the flight. Systems functioned normally through the early stages, but a deviation was observed towards the latter part of the mission trajectory. This deviation prevented the vehicle from placing its payloads into the intended orbit.

In a brief televised statement following the launch attempt, ISRO Chairman Dr. V. Narayanan said that mission data was being analysed and that a clearer picture would emerge after a thorough review. He emphasised that preliminary observations indicated an anomaly during one of the later stages of the rocket’s flight, and assured that the organisation would share findings once the analysis is complete.

This mirrors observations from the earlier PSLV-C61 mission in May 2025, which also experienced difficulties during a similar phase of flight. With both missions showing comparable patterns, experts believe the review will focus on identifying common technical factors and ensuring corrective measures are implemented.

About the Lost Payloads

The primary satellite aboard PSLV-C62 was an Earth observation spacecraft designed to enhance India’s monitoring and data-gathering capabilities. Developed with advanced imaging technology, the satellite was intended to support a wide range of applications, including environmental studies, resource management, and other national requirements.

In addition to the main satellite, the mission carried multiple smaller satellites from India and other countries. Many of these payloads were developed by academic institutions and emerging technology companies, with objectives ranging from experimental research to technology demonstrations in space. The setback has therefore impacted not just national programmes but also collaborative and educational initiatives linked to the mission.

Importance of PSLV in India’s Space Programme

The PSLV has been a cornerstone of India’s space efforts for over three decades. Since its first successful flight, it has completed dozens of missions, earning a reputation for reliability and precision. It has played a key role in launching Earth observation satellites, scientific missions, and payloads for international customers.

While any launch system can experience occasional technical challenges, back-to-back setbacks naturally draw attention, given PSLV’s long track record. Space analysts point out that understanding and addressing the root cause swiftly will be crucial for maintaining confidence among domestic stakeholders and international partners.

Review Process and Transparency

ISRO traditionally conducts a detailed internal review following any mission anomaly. These reviews are carried out by expert committees that examine telemetry data, system performance, and manufacturing processes. Historically, summary findings from such reviews have been made public after submission to the government.

In the current case, observers note that reports related to earlier mission reviews are still awaited in the public domain. While officials have indicated that findings have been shared with authorities, there is growing interest in greater transparency to reassure partners and the broader scientific community.

Given ISRO’s increasing role in launching satellites for foreign governments, universities, and private firms, experts underline that clear communication about corrective actions will be important for sustaining trust and future collaborations.

Looking Ahead

Despite the recent challenges, space experts stress that setbacks are part of the learning curve in complex technological systems. Each mission provides valuable data that helps strengthen future performance. ISRO continues to work on multiple upcoming launches, including missions using other launch vehicles, as well as scientific and exploratory projects.

Officials have reiterated that safety, reliability, and mission assurance remain top priorities. The findings from the ongoing analysis are expected to guide improvements in design checks, quality control, and testing procedures before the next PSLV flight.

As India’s space ambitions expand across scientific research, commercial launches, and international cooperation, ensuring the robustness of its launch systems will remain central.
