EARTH OBSERVATION SATELLITES (EOS)-03 MISSION

In 2021, a high-level panel was established to examine the failed Geosynchronous Satellite GSLV-F10/Earth Observation Satellites (EOS)-03 mission and recommended measures for making the Cryogenic Upper Stage (CUS) more robust.
The Geosynchronous Satellite Launch Vehicle (GSLV) with improvements added to its CUS is expected to be ready in the second half of this year.
GSLV is a space launch vehicle designed, developed, and operated by the Indian Space Research Organisation (ISRO) to launch satellites and other space objects into Geosynchronous Transfer Orbits.
GSLV has been designed for launching communication satellites.
Geosynchronous satellites are launched into orbit in the same direction the Earth is spinning and can have any inclination.
The satellites in the geosynchronous orbits appear to remain permanently fixed in the same position in the sky.
GSLV has the capability to put a heavier payload in orbit than the Polar Satellite Launch Vehicle (PSLV).
It is a three-stage launcher with strap-on motors.

Cryogenic Upper Stage

GSLV follows a solid fuel first stage with another liquid fuel stage coming next. The second stage is followed by a third stage known as CUS.
It was the rocket’s crucial third stage, which then failed to ignite and led to the failure of the GSLV-F10.
The cryogenic stage is technically a very complex system compared to solid or earth-storable liquid propellant stages due to its use of propellants at extremely low temperatures and the associated thermal and structural problems.

Earth Observation Satellites

Earth observation satellites are the satellites equipped with remote sensing technology.
Earth observation is the gathering of information about Earth’s physical, chemical and biological systems.
Many earth observation satellites have been employed on sun-synchronous orbit.
