The failure of the recent PSLV-C61/EOS-09 mission has been attributed to a 'small' issue, according to ISRO chairman V. Narayanan. And while the details will reportedly be revealed in a report soon to be submitted to India's Prime Minister, the space agency has completed its failure analysis of the mission.

The countdown for the launch of the EOS-01 satellite as part of the PSLV-C61 mission was halted just one minute before the rocket's scheduled launch. The Indian Space Research Organization (ISRO) has completed a detailed failure analysis of the PSLV-C61/EOS-09 mission and will soon submit a report to India's Prime Minister, according to ISRO chairman V. Narayanan. The space agency revealed that the mission failure, which resulted in the countdown being halted just one minute before the rocket's scheduled launch, was caused by a "small issue."

"We have completed the failure analysis. It was a small issue, but I can't disclose the details before submitting the report," Narayanan told Times of India. The ISRO chief stated that the analysis was completed within days of the mission's failure on August 12.

EOS-01 is a radar imaging satellite designed to provide high-quality images under all weather conditions for military intelligence, agricultural planning, and disaster relief applications. The satellite was supposed to be released about 15 minutes after launch.

The countdown for the mission was halted at T-1 minute and 10 seconds, marking the first time that a PSLV mission had to be aborted at such a late stage. The ISRO has announced that it will make public the findings of the investigation into the mission failure once the report has been submitted to the Prime Minister.

This latest development highlights the importance of rigorous failure analysis in the space industry, ensuring that issues are identified, addressed, and avoided in future missions. With a growing space sector, India is increasingly becoming a key player in the global space industry, developing cutting-edge technologies and achieving historic milestones.
