Sriharikota, September 3, 2026: The Indian Space Research Organisation (ISRO) is preparing for the launch of its EOS-05 Earth observation satellite aboard the GSLV-F17 rocket. The mission is scheduled for September 4, 2026, at 2:55 AM IST from the Second Launch Pad at the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
The mission is attracting significant attention because EOS-05 will become India’s first imaging satellite designed to operate from a geosynchronous orbit. From its high-altitude position, the satellite will be able to repeatedly observe large areas of the Earth.
What Is EOS-05?
EOS-05 is an advanced Earth observation spacecraft developed for applications that require detailed and repeated observation of the Earth’s surface.
Unlike conventional Earth-observation satellites that move across different parts of the planet, a satellite operating from a geosynchronous orbit can remain synchronized with Earth’s rotation. This allows it to maintain frequent observations of a particular region.
The capability could be useful for monitoring weather patterns, natural disasters, environmental changes and other large-scale developments.
GSLV-F17 Mission
The satellite will be carried into space by GSLV-F17, the 19th flight of India’s Geosynchronous Satellite Launch Vehicle.
According to ISRO, the rocket will initially place EOS-05 into a Sub-Geosynchronous Transfer Orbit (Sub-GTO). The launch will take place from the Second Launch Pad at the Satish Dhawan Space Centre.
The mission is also significant because it represents ISRO’s return to launches after a months-long gap following its previous launch attempt earlier this year.
Why the Mission Matters
EOS-05 is expected to strengthen India’s Earth-observation capabilities. Frequent imaging from a geosynchronous orbit could provide useful information for disaster management, weather observation and environmental monitoring.
The satellite’s ability to repeatedly observe large regions could also help authorities respond more quickly to certain natural events.
