ISROa��s longest ever launch successful

Sriharikota:A�Indian Space Research Organisation(ISRO) has successfully positioned advanced weather satellite SCATSAT-1 and other seven satellites into the orbits in its longest ever launch mission, which lasted over two hours and fifteen minutes.

The Polar Satellite Launch Vehicle(PSLV-C35) carrying eight satellites launched from the First Launch Pad (FLP) of Satish Dhawan Space Centre in Sriharikota on Monday morning at 9:12 AM.

This is the first time that satellites were placed in two different orbits with a single rocket. After launch in 17 minutes SCATSAT-1 was placed in the polar synchronous orbit at an altitude of 670km.

SCATSAT-1, weighing 371 kg for weather related studies including cyclone detection and tracking, will succeed the now defunct Oceansat-2 satellite launched in 2009. ISRO Chairman A S Kiran Kumar siad SCATSAT-1 would be a stop gap arrangement between Oceansat-1 and Oceansat-2.

Immediately after SCATSAT-1 injection, seven co-passenger satellites were placed into polar Sun Synchronous Orbit at an altitude of 689 km. Co-passenger satellites are ALSAT-1B, ALSAT-2B, ALSAT-1N from Algeria, NLS-19 from Canada and Pathfinder-1 from USA as well as two satellites PRATHAM from IIT Bombay and PISAT from PES University, Bengaluru.

Mission Director B Jayakumar said, a�?The mission had many complexities in planning. A�PSLV now has the flexibility to suit customer demands.a�?

Placing satellites in different orbts will also facilitate launching more such commercial satellites in the future.

Earlier, for launching satellites into different orbits, ISRO had to build separate rockets. Each separate PSLV would cost around 120 crore on an average. Now with one rocket ISRO can launch several satellites and place them in different orbits, thus saving costs.
