GSLV rocket of Indian Space Research Organisation (ISRO) failed to put India’s largest earth observation satellite (EOS-3) into the orbit. It failed because of failure to ignite the cryogenic stage of the GSLV.
Highlight
-
It failed even though the first and second stage of the rocket had performed normally.
-
ISRO’s operation was started after facing several hurdles caused by the Covid-19 pandemic.
-
The rocket was to place the satellite in orbit with an objective of providing near real-time imaging of large areas of India at frequent intervals and for quick monitoring of natural disasters.
About the Launcher
-
This 51.7-metre-tall rocket comprises four stages lifted off majestically on August 12.
-
It was supposed to place the EOS, the state-of-the-art satellite into Geosynchronous Transfer Orbit.
-
It is the eighth flight with indigenous cryogenic engine and 14th flight of GSLV.
-
It also marks the 79th launch vehicle mission from Sriharikota.
Background
The GSLV satellite, originally called as GISAT-1, was scheduled to be launched on March 5, 2020. However, it was postponed before the lift-off due to ‘technical errors’. Later, the Covid-induced lockdown delayed the mission. Post-lockdown, it was scheduled to launch on March 28, 2021 but it was again postponed due to ‘minor issues’ with the satellite.
Objective of the mission
Objective of this mission was:
-
To provide near real-time imaging at frequent intervals of large area regions,
-
Quick monitoring of natural disasters and episodic events
-
To obtain spectral signatures for agriculture, forestry, water bodies including disaster warning, cloud burst, cyclone monitoring and thunderstorm monitoring.
