Indian rocket fails to launch GISAT-1/EOS-3 satellite
Sriharikota (Andhra Pradesh) August 12, 2021
The much-awaited launch of India's first Geo-Imaging Satellite (GISAT-1), renamed as EOS-03, failed on Thursday.
About seven minutes into its launch at 5.43 a.m. the Indian rocket Geosynchronous Satellite Launch Vehicle (GSLV-F10) encountered problems in its cryogenic engine - the third and last engine.
The rocket could not send details to the Indian Space Research Organisation's (ISRO) ground centre at the spaceport in Sriharikota.
Announcing the mission failure K. Sivan, Chairman, ISRO said: "Technical anomaly was observed in the cryogenic stage and the mission could not be accomplished."
Originally the GISAT-1/EOS-03 was slated for launch on March 5, 2020, but hours before the launch, ISRO announced postponement of the mission owing to some technical glitch.
Soon after, the Covid-19 pandemic and the lockdown delayed the mission. The rocket had to be dismantled and cleaned up.
The satellite also underwent a name change from GISAT-1 to EOS-03.
Subsequently, the GISAT-1/EOS-03 launch was slated for March 2021 but due to problems in the satellite's battery side, the flight got delayed again.
With the replacement of the battery, the satellite and the rocket were being readied for their flight at Sriharikota when the second wave of Covid-19 swept in, affecting many at the rocket launch centre.
The Indian space agency had earlier said the 2,268 kg GISAT-1/EOS-03 would provide a real-time image of a large area of region of interest at frequent intervals.
It will also enable quick monitoring of natural disasters, episodic events, and any short-term events.
The satellite had a payload of imaging sensors of six band multi-spectral visible and near infra-red with 42 metres resolution, 158 bands hyper-spectral visible and near infra-red with 318 metres resolution, and 256 bands hyper-spectral short wave infra-red with 191 metres resolution.
