Sriharikota (AP), Aug 12 (UNI) The Indian Space Research
Organisation (ISRO) could not accomplish GSLV-F10/EOS-03
mission as the upper cryogenic stage failed to ignite, about five
minutes after lift off from the Satish Dhawan Space Centre on
Thursday.
ISRO sources said ater a smooth 26-hour countdown. the
57.10 m tall GSLV-F10, weighing 416 ton,, carrying the
2,268 kg agile Earth Observation Satellite (ES-03) took off
as scheduled at 0543 hrs from the Second Launch Pad at
the SHAR Range.
The performance of the first and second stages of the three
stage vehicle were normal. However the third stage--Cryogenic
Upper Stage--ignition did not take place due to a technical
anomaly and the satellite could not be placed in the intended
Geostationary Orbit.
The ignition of the cyro stage should have happened about five
minutes after the lift-off.
Addressing the scientists ISRO Chairman K.Sivan said that a
"technical anomaly was observed in the cryogenic stage and
the mission could not be accomplished."
ISRO in an update said "GSLV-F10 launch took place at 0543 hrs
as scheduled. Performance of first and second stages was normal.
However, Cryogenic Upper Stage ignition did not happen due to
technical anomaly. The mission couldn't be accomplished as
intended.

GSLV-F10 is a three stage launch vehicle with the solid and liquid
fuels in the first two stages respectively. The third is the cryogenic
stage.
The aim of the mission was to place EOS-03 in Geostationary orbit.
The satellite was expected to provide near real-time imaging of
large area of interest at frequent intervals, which could be used
for quick monitoring of natural disasters, episodic events and any
short-term event.
This failure is all the more surprising because the rocket launches
since 2017 have been successful, and this failure breaks a long streak
of successful launches.
Right from the beginning the GSLV-F10 mission appeared to be a jinxed
one for ISRO in its bid to place its first Geo-Imaging Satellite-1
(GISAT-1) or Earth Observation Satellite-03 (EOS-03) in the Orbit.
Originally the GISAT-1 was slated for launch on March five last year.
However, it was postponed at the last minute due to a technical glitch.
Soon after this, the Covid-19 pandemic broke out and the subsequent
lockdown delayed the mission. Due to the delay, the rocket had to be
dismantled and cleaned up.
Subsequently, the GISAT-1 launch was slated for March this year,
but due to problems in the satellite's battery side, the flight once
again got delayed.
After replacement of the battery. the satellite and the rocket was readied
for the mission when the second COVID wave led to further delay.
When ISRO finally took up the mission, it surprisingly failed as the third stage
fails to get ignited and the satellite could not be placed in the geostationary orbit.
