Bengaluru, February 6: Indian Space Research Organization ISRO is set to create history by launching 104 satellites in one go on February 15. This will be a record setter as none of the space agencies across the globe has achieved but ISRO will launch 104 satellites including 101 foreign satellites into its orbit on its PSLV-C37 rocket.
The launch will take place from Satish Dhawan Space Centre in Sriharikota in Andhra Pradesh. No space agency has launched such a large number of satellites in a single flight so far. S. Somnath, Director of the Liquid Propulsion Systems Centre of the Indian Space Research Organisation said that “we are making a century by launching over 100 satellites at one go.
How the satellites will be placed?
Every satellite will be separated in different angle and at different time from the launch vehicle in order to prevent collision between satellites. Dr. K. Sivan, Director of the Vikram Sarabhai Space Centre (VSSC), said that “The satellite that gets launched first will move at a relatively faster velocity than the next satellite that is launched. Due to different relative velocities, the distance between the satellites will increase continuously but the orbit will be the same.”
All the 101 foreign satellites belong to Israel, Kazakhstan, Netherlands, Switzerland, and the US. 88 satellites are from US. The collective weight of foreign satellites will be nearly 500kg. The three Indian satellites are Cartosat-2 series weighing 730 kg as primary payload, INS-IA and INS-1B, totally weighing 30 kg.
The official from ISRO said that “We have tentatively decided to launch the satellites at one go around 9 a.m. into the sun-synchronous orbit, about 500 km above the earth.” On speaking about the positioning about the satellites it said that a 320-tonne rocket-Polar Satellite Launch Vehicle (PSLV-C37) will launch all the satellites with a combined weight of 1,500 kg, including the 650 kg remote-sensing Cartosat-2 and two nano-satellites (IA and IB) weighing 15 kg each.”
In 2016, ISRO launched 20 satellites in one go where as on February 15 ISRO will set a record by launching 104 satellites in one go.
