ISRO's 101st launch: EOS-09 mission could not be accomplished, says chief Narayanan - VIDEO
Indian Space Research Organisation (ISRO) chief V Narayanan said on Sunday (May 18) that its 101st mission —PSLV-C61/EOS-09 mission which was launched on Sunday morning — “could not be accomplished”.
ISRO’s 101st launch mission with PSLV-C61 was launched at 5:59 am IST on Sunday. It carried EOS-09, a 1696 kg Earth observation satellite, which was supposed to be placed into a Sun-Synchronous Polar Orbit.

Few minutes after the launch, ISRO chief chief Narayanan said, “Today we targeted the 101st first launch from Sriharikota [in Andhra Pradesh]. The PSLV-C61/EOS-09 mission was targeted.”
He explained, “The PSLV is a four stage vehicle. Up to the second stage, the performance was quite normal. Third stage, motor started perfectly. But during the functioning of the third stage, we are seeing a observation. And the mission could not be accomplished. After analysis. we shall come back. Thank you.”
ISRO also posted on X, “Today 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.”
EOS-09, short for Earth Observation Satellite-09, is a repeat satellite of EOS-04. This is the 63rd flight of the PSLV rocket, and the 27th using the PSLV-XL, completing a total 100 launches before May 18.

ISRO said the spacecraft was a debris-free mission. A sufficient amount of fuel has been reserved for de-orbiting the satellite after its effective mission life, lowering it to an orbit that ensures its decay within two years.
The spacecraft is configured using ISRO’s RISAT-1 heritage bus, with most of the functional requirements of the SAR payload and the bus platform systems derived from the earlier ISRO missions.
The mission carried a Synthetic Aperture Radar (SAR) payload capable of providing images for various earth observation application under all-weather condition.
