The 63rd PSLV launch of the Indian Space Research Organisation (ISRO) to place the EOS-9 surveillance satellite in orbit was unsuccessful due to a decrease in pressure during the third of four stages.
As per ANI, space strategist PK Ghosh stated that the unfortunate failure encountered by the Indian Space Research Organisation (ISRO) in the launch of its 101st satellite, EOS-09, aboard the Polar Satellite Launch Vehicle (PSLV-C61), should be used as a learning process, and not to get demotivated by this failure.
Speaking with ANI, Ghosh also said, “It is slightly unfortunate, but I do not like to use the term `failure`. Every launch is a learning process. We assume that there was some problem in the third stage. This is our 101st launch; we had remarkable success… I am sure we will learn from this and go forward in our next launch.”
Earlier in the day, ISRO Chief V Narayanan announced that the launch was not successful, and experts are currently analysing the entire process.
While addressing a media briefing, V Narayanan, the ISRO chief, said the first two stages after the launch performed as we expected, but unfortunately things could not go our way during the third stage.
“Today we attempted a launch of the PSLV-C61 vehicle. The vehicle is a 4-stage vehicle. The first two stages performed as expected. During the 3rd stage, we observed some anomalies. The mission could not be accomplished. We are studying the entire performance; we shall come back at the earliest,” Narayanan stated as reported by ANI.
Moreover, the flight sequence of the PSLV-C-61 consists of various stages, starting from the ignition of PS1 and PSOM at the ground to the separation of various sections to finally the separation of the satellite from the rocket. As per the ISRO chief, the major problem detected at the third stage was quite a complex one. He further explained that there is a solid rocket motor which provides the upper stage with a high thrust after the atmospheric phase of the launch. This stage has a maximum thrust of 240 kilonewtons. However, this is where the ISRO chief suggested some technical problem that resulted in the failure of this launch.
This was ISRO`s 101st launch, and the Earth Orbiting Satellite, also known as EOS-09, was intended to be placed in a Sun Synchronous Polar Orbit (SSPO) if the mission had succeeded.
Moreover, the EOS-09 satellite was scheduled to be deployed as Orbit Change Thrusters (OCT) to lower the PS4 stage`s altitude. This is followed by passivation, a procedure designed to reduce the stage`s orbital life while assuring acceptable space operations. EOS-09 is intended to provide continuous and dependable remote sensing data for usage in various operating sectors.
As informed by the experts and officials, EOS-09 is a sophisticated Earth observation spacecraft that uses C-band synthetic aperture radar technology. It can capture high-resolution photographs of the Earth`s surface in any weather, day or night. This capability strengthens India`s monitoring and management systems across numerous sectors.
