ISRO forms committee to analyse rare PSLV-C61/EOS-09 mission failure

Chennai, May 19 (UNI) The Indian Space Research Organisation (ISRO) has formed
a committee to analyse the failure of yesterday's PSLV-C61/EOS-09 mission and
recommend measures.
The Failure Analysis Committee would go into the reasons for the glitch that appeared
during the third stage (with solid propellants) of the four-stage workhorse launch vehicle,
resulting in deviation in trajectory and the mission could not be accomplished.
According to ISRO Chairman V.Narayanan, the committee would study the causes that
led to the glitch in the third stage and recommend measures to be incorporated in the
future missions to prevent failures.
ISRO said "on 18th May 2025, 101st launch was attempted, PSLV-C61 performance
was normal till 2nd stage. Due to an observation in 3rd stage, the mission could not be
accomplished".
The technical glitch appeared about eight minutes after the PSLV-C61, carrying the
earth observation satellite EOS-09 that has the capability to take high resolution images
on all weather conditions day and night, besides boosting surveillance in border areas
of India in the wake of tensions in Indo-Pak ties following Operation Sindoor, took off
from the First Launch Pad after a smooth 22-hr countdown.
About 17 minutes after lift off, the workshorse rocket of ISRO was to inject the satellite
into a Sun Synchronous Polar Orbit (SSPO). However the mission could not be
accomplished.
“Today from Sriharikota the PSLV-C61/EOS-09 mission was targeted. the PSLV is
a four stage vehicle and the second stage performance was quite normal. The third
stage motor started perfectly but during the functioning of the third stage we are
seeing an observation and the mission could not be accomplished. After analysis
we shall come back,” Dr Narayanan said.said.
It is a rare PSLV failure for ISRO for which it has been the most trusted launch
vehicle having placed hundreds of satellites in varied orbits, including carrying
over 100 satellites in a single mission, besides the prestigious Chandrayaan.
In its 63rd flight, this is the second failure of PSLV in its chequered history after
the failure of its first developmental flight more than two decades ago.
Apart from the initial failure, PSLV has been a resounding success for ISRO
with several space faring nations choosing it as the most trusted and preferred
launch vehicle for launching its satellites in various orbits from Indian soil.
