ISRO begins 48-hr countdown for launch of 20 satellites from Sriharikota

The Indian Space Research Organization, ISRO begins its 48-hour countdown for the launch of a record 20 satellites from the Satish Dhawan Space Centre, Sriharikotta at 9.26 am today. The Mission Readiness Review Committee and the Launch Authorization Board of the national space agency met last night and gave their approval for the countdown. The payloads will be taken aboard the proven workhorse PSLV C34 that will be ignited at 9.26 am on Wednesday and put them on a 505 km sun synchronous orbit one after the other.

The satellites include Cartosat-2 Series remote sensing payload of India for earth observation purposes, two Indian students satellites and 17 other micro and nano satellites of foreign customers from the US, Canada, Germany and Indonesia. 

The second launch pad of the national spaceport at Sriharikotta in Andhra Pradesh,



some 90 kilometers off Chennai, is now buzzing with activities, as the countdown is set to start for a historic launch on Wednesday. The high profile mission has importance not only for the record number of payloads. Once the PSLV C34 puts the satellites into their circular low earth orbits, it will not wind up its operation immediately, as it used to be in the past. 

Dr Deviprasad Karnik, Director-Public Relations of ISRO told, this time after injecting the satellites, the rocket will go further up into space simply using its initial velocity, and then will be reignited twice at regular intervals of 50 minutes. A similar experiment with a single reignition of the PSLV on December 16 last year proved to be a grand success. More such experiments will enable ISRO to put many satellites at different heights in a single mission in future.
