PSLV-C61 Mission Failure | Reasons Behind ISRO Rocket Failure Explained

Why Did ISRO’s Trusted PSLV-C61 Rocket Fail? Complete Explanation

Focus Keywords: PSLV-C61 Failure, ISRO Rocket Failure, PSLV Mission Analysis

The Indian Space Research Organisation (ISRO) recently faced a significant setback when its highly dependable rocket, PSLV-C61, mission failed. This mission, counted as ISRO’s 101st launch, was unsuccessful due to a technical malfunction occurring in the third stage of the rocket that prevented the satellites from reaching their intended orbit. This article explains the mission details, cause of malfunction, and ISRO’s plans going forward.

PSLV: ISRO’s Reliable Workhorse Rocket

The Polar Satellite Launch Vehicle (PSLV) is ISRO’s most frequently used launch vehicle, boasting an overall success rate of more than 98%. Using PSLV, India has successfully launched numerous domestic and international satellites, establishing a strong position in the global space market.

Details of the PSLV-C61 Mission

Launched in 2024, the PSLV-C61 mission aimed to place small and medium-sized satellites into Low Earth Orbit (LEO). However, minutes after liftoff, a technical issue arose in the third stage (PS3), impacting the mission’s success.

Key Highlights of the Mission:

ISRO’s 101st PSLV launch
Carried three major satellites and multiple smaller CubeSats
Observed irregularities in third-stage tracking and thrust

What Was the Third Stage Malfunction?

According to ISRO’s preliminary reports, the third stage of the PSLV-C61 faced an unexpected thrust reduction. This stage is critical as it provides the required velocity and direction for accurate satellite placement. Potential causes under investigation include issues with fuel supply, sensor failures, or navigation system errors. A detailed inquiry is currently underway.

Impact on ISRO’s Reputation

This rare failure is considered an exception in ISRO’s otherwise stellar track record. ISRO’s achievements with missions like Chandrayaan-3 and Mars Orbiter demonstrate its competence. This setback is unlikely to damage ISRO’s global standing but will serve as a valuable learning opportunity to improve future missions.

Next Steps for ISRO

ISRO has formed a high-level committee to conduct an exhaustive failure analysis. Additional safety measures and enhanced monitoring systems will be deployed in future launches to prevent similar incidents.

Human Perspective

An ISRO senior scientist remarked, “Every failure teaches us where improvement is needed. Failure in science is not the end but a new beginning.” This resilient approach defines ISRO’s strength and progress.

Conclusion

The PSLV-C61 mission failure underscores the challenges inherent in space exploration. While not every mission yields success, failures pave the way for stronger comebacks. With its expertise, ISRO is expected to overcome these challenges and continue its advancement in space technology. India’s pride in ISRO remains steadfast, and optimism for future missions is high.

Frequently Asked Questions (FAQ)

1. What caused the failure of the PSLV-C61 mission?

The failure was due to a malfunction in the rocket’s third stage, which reportedly experienced a thrust reduction possibly caused by fuel, sensor, or navigation issues. The exact cause is under investigation.

2. How many times has PSLV failed before?

PSLV had only two prior failures: once in its maiden flight in 1993 due to software errors and again in 2017 due to heat shield separation failure. PSLV-C61 marks the third mission failure in over 63 launches.

3. What is the significance of the PSLV rocket for ISRO?

PSLV is ISRO’s most successful launcher, known as its workhorse, responsible for deploying numerous satellites into various orbits, including geosynchronous and sun-synchronous, and supporting pivotal missions like Chandrayaan and Mangalyaan.

4. What satellite was onboard PSLV-C61?

The mission was carrying EOS-09, an Earth observation satellite featuring Synthetic Aperture Radar (SAR) technology for high-resolution images in all weather conditions.

5. What steps will ISRO take after this failure?

ISRO has set up a high-level failure analysis committee and plans to enhance safety and monitoring systems for upcoming missions to avoid similar failures.
