ISRO successfully launched the EOS-05 satellite aboard the GSLV-F17 rocket from the Second Launch Pad at Satish Dhawan Space Centre on September 4, 2026. ^[1] Official sources stated that EOS-05 will be India's first ever imaging satellite from a geosynchronous orbit. ^[2] The GSLV-F17 rocket, standing 51.7 metres tall, lifted off at 2:55 am IST from a spaceport located approximately 135 km from Chennai amid rainy conditions. ^[3] ISRO stated the objective of the mission is to provide near-real-time imaging of large-area regions for quick monitoring of natural disasters and episodic events. ^[4] The EOS-05 mission utilized the GSLV-F17 rocket, which is 51.7 meters tall. ^[5] This mission marks the first time ISRO has launched a satellite from a Geosynchronous orbit. ^[6] ISRO's mission brochure specifies that the transfer orbit has a perigee of 170 kilometres and an apogee of 28,934 kilometres with an inclination of 19.28 degrees to the equator. ^[7] The EOS-05 mission aims to provide near-continuous imagery of a broad region by operating from a geosynchronous altitude of roughly 36,000 kilometres above Earth. ^[8] The GSLV-F17 rocket placed the 2,367-kilogram EOS-05 satellite into a sub-geosynchronous transfer orbit, which is a temporary, highly elliptical path rather than the final operational orbit. ^[9] The rocket blast-off occurred at the end of a 27-hour countdown that started at 23:30 hours on Wednesday. ^[10]
