When the Countdown Ended, ISRO Had Its Moment

New Delhi, September 04, 2026 India’s space journey received a fresh boost in the early hours of September 4 as ISRO successfully launched the GSLV-F17 mission from Sriharikota. The achievement came at a crucial time for the space agency, which had recently faced a series of challenges with its launch programme. Against this backdrop, the successful deployment of EOS-05 became a significant moment of recovery and renewed confidence. More than just another mission, the launch reflected ISRO’s ability to overcome setbacks and continue its pursuit of ambitious goals. At 2:55 AM, scientists, engineers and support teams across launch centres, mission control rooms and tracking stations were fully focused on the operation. Nineteen minutes later, at 3:14 AM, the mission’s success sparked celebrations among the teams involved. Science Minister Dr Jitendra Singh described the achievement as 'Another giant leap for India in Space! Kudos to Team ISRO on the successful launch of GSLV-F17/EOS-05. EOS-05 is a state-of-the-art Earth Observation satellite and India's first imaging satellite from Geosynchronous Orbit, enabling advanced imaging across visible, infrared, multi-spectral and hyperspectral bands.' The successful launch carried special importance because ISRO had recently faced consecutive setbacks with its PSLV programme. Failures in 2025 and January 2026 led to detailed investigations and corrective efforts, while the PSLV fleet remains grounded pending further testing and clearance. The incidents also underlined the complex nature of rocket launches, where even established systems can face unexpected technical challenges. The GSLV-F17 mission, meanwhile, became the 107th launch of a large rocket from Sriharikota. With the PSLV temporarily unavailable, attention shifted towards the GSLV Mk II, a vehicle known within ISRO by the unusual nickname "naughty boy." Its record has been far from smooth, with six failures in 19 launches, giving the rocket a reputation for an unpredictable journey. Yet, despite this difficult history, the GSLV Mk II has also played a major role in strengthening India’s independent space capabilities and advancing its technological ambitions. The latest success, therefore, represents more than the launch of an Earth observation satellite. It reflects ISRO’s determination to learn from failures, address challenges and return stronger. At a time when confidence in India's launch capability was being closely watched, the GSLV-F17/EOS-05 mission delivered a timely message: setbacks may test a space programme, but resilience and persistence can help it rise again.
