ISRO to launch record 103 satellites on a single rocket
The Indian Space Research Organisation (ISRO) is planning to set a new world record in space history by launching 103 satellites in one go on a single rocket in the first week of February, 2017.
These satellites will be launched on board of ISRO’s workhorse PSLV (C37) from the Satish Dhawan Space Centre in Sriharikota in Andhra Pradesh. The mission will carry three satellites from India and rest from other countries.
How these satellites will be placed in orbit?
- The satellites will be separated from vehicle in different directions, once launch vehicle reaches the orbital condition. The separation angle and time of separation will be different for every satellite.
- The separated satellites will have relative velocity of one metre per second. So after 1,000 seconds distance between satellite and rocket will be 1,000 metres. It will ensure that satellite will not collide with another.
- The first satellite launched will move at relatively faster velocity than the next satellite. Due to different relative velocities, distance between the satellites will increase continuously but the orbit will remain same.
The present record of highest number of satellites launched in a single mission has been 37 by Russia in 2014. NASA has launched 29 satellites in one go in 2013. In June 2016, ISRO had launched 20 satellites in one go.
