The 28 hour count down for PSLV C 37 has been progressing smoothly since 5-28 am this morning. ISRO Scientists at the Sathish Dhawan Space Centre Sriharikota are expecting a historic launch at 9.28 tomorrow morning. Last minute tests are being conducted for a perfect departure. <br/><br/>A total of 104 satellites will be piggy backed in the 16th extended version of the launch vehicle. Scientists said, within 25 to 28 minutes all the satellites will be injected into their prescribed orbit after being dispatched in space. <br/><br/>Hundred and one nano satellites are being launched as part of the commercial arrangements between Antrix Corporation limited, the commercial arm of ISRO and the international customers like the United States, Israel, Kazhaksthan, the Nederland, Switzerland and the United Arab Emirates.

The rocket carrying India's principal payload Cartosat-2 Series and 103 other co-passangers will lift off from the first launch pad of the Satish Dhawan Space Centre, Sriharikotta at 9.28 AM tomorrow. <br/><br/>AIR correspondent reports that this is considered to be the world's highest number of satellites to be inserted into space in a single launch. PSLV C37 will carry Cartosat – 2 series satellite and two more nano satellites weighing below ten kilogram in satellites from other countries, the maximum are from 96 from the United States and one each from Israel, Kazhaksthan, the Nederland, Switzerland and the United Arab Emirates. Through this mission, India will be second to none in the world beating all records. Cartosat-2 series satellite will have a high resolution camera to monitor.
