ISRO's 101st mission from here, an earth observation satellite onboard the agency's trusted PSLV rocket, could not be accomplished on Sunday following a pressure issue in the third stage of the launch vehicle, the space agency said.
Although the Polar Satellite Launch Vehicle (PSLV) made a textbook lift-off at the prefixed time of 5.59 am, the mission objectives, however could not be achieved.

"Today we targeted the 101st launch from Sriharikota, the PSLV-C61 EOS-09 mission. The PSLV is a four-stage vehicle and up to the second stage, the performance was 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," Narayanan said.
