History of sorts was created today when ISRO successfully launched its 100th satellite in space today. India’s space workhorse, the PSLV launched 30 other satellites with 2 more belonging to India and the rest from countries like France, Finland, Korea, Canada, the United States and the United Kingdom. The 42nd launch comes in the wake of failure, which occurred on August 31 last year due to a freak accident.
The countdown for the launch, which began on 5.29 am on Thursday, came to an end when the PSLV successfully lifted off from Sriharikota in Andhra Pradesh at 9.29 am. There was a delay of a minute for the lift-off to avoid the possibility of colliding with space debris. The uniqueness of this mission according to scientists lies in the fact that thirty satellites were launched in one orbit about 550 km above the surface of earth while the remaining single went into the orbit, which was 359 km above the earth. The duration of placement of satellites will last for 2 hours and 21 minutes. The technology used for the operation is referred to as the ‘multiple burn technology’. In this, the height is controlled by switching off and then switching on the rocket engine.
The PSLV rocket, whose weight and height dimensions stand to about 320 tonnes and 44.4 meters, respectively, includes among its payload, the 710 kg weighing earth observation satellite, the third in the Cartosat 2 series. Denying allegations of sabotage ISRO had attributed the cause of the unsuccessful launch last August to the failure of important but tiny equipment of the rocket. This had prevented the separation of the protective heat shield. This offers protection from the enormous heat that is generated during take-off as friction takes place with the atmosphere. The last launch though unsuccessful was essential because of the malfunctioning of three atomic clocks of one of the satellites.
President Ram Nath Kovind and Prime Minister Narendra Modi sent their congratulations to the scientists at ISRO after the PSLV-C40’s successful launch.
