India Launched 7 Satellites Atop PSLV Rocket
India's Polar Satellite Launch Vehicle (PSLV) lifted off from India's Satish Dhawan Space Centre last month.
The main payload was the DS-SAR, a 794-pound (360 kilograms) satellite designed to image Earth in radar light. (SAR stands for "synthetic aperture radar."), according to Space.com

00:00 -15, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, +5 seconds.
00:24 And we have a lift off.
00:32 -Yes, you just saw the successful lift off of the PSLV-C56.
00:40 The first stage of the lift off is normal.
00:45 It will run for about 110 seconds.
00:51 It is producing 4,800 kN of power.
00:57 -Normal thrust of PS-1 stage, 4,800 kN.
01:04 The stage is 20 m long and 2.8 m in diameter.
01:20 -The rocket is passing through its maximum speed.
01:27 This is a very difficult area for a rocket.
01:33 But the rocket has to keep its course with the help of SITVC and RCT.
01:39 And currently all the systems are working normally.
01:44 And the first stage is in progress.
01:47 -Presently the launch vehicle trajectory is being tracked by SHAR stations.
