From Most Inconsistent To National Hero, All About ISRO’s 'Naughty Boy'

Meet ISRO's 'Naughty Boy': ISRO's GSLV-F17 has successfully launched EOS-05, an Earth observation satellite nicknamed the “Naughty Boy.” The mission marks a major step forward for India's space program.
Why 'Naughty Boy'?: The nickname comes from the GSLV's earlier reputation for inconsistent performance. The successful GSLV-F17 mission now gives the rocket a major confidence boost.
Meet EOS-05: EOS-05 is an advanced Earth observation satellite designed to provide frequent imaging of large areas. It is set to operate from a geosynchronous orbit.
A Record-Breaking Payload: Weighing 2,367kg, EOS-05 is the heaviest satellite ever launched by a GSLV. The achievement demonstrates the launch vehicle's improved payload capability.
Going 36,000km Up: EOS-05 is being moved toward an operational orbit roughly 36,000km above Earth. From there, it can repeatedly observe the same broad region.
India's New Eye in the Sky: The satellite can capture imagery across visible, infrared, multispectral and hyperspectral bands. These capabilities can support agriculture, forestry, water monitoring and disaster management.
Watching Extreme Weather: EOS-05 is designed to provide frequent observations that can help monitor cyclones, cloudbursts and thunderstorms. Faster access to such data could strengthen disaster preparedness.
A Major GSLV Comeback: The mission follows the unsuccessful GSLV-F10/EOS-03 launch in 2021. Its success demonstrates progress in GSLV performance and cryogenic propulsion reliability.
Strategic Data For India: Once operational, EOS-05 is expected to become India's first dedicated imaging satellite from geosynchronous orbit. It could provide high-frequency Earth observation data for national applications.
