Things are getting set for the launch of India's Radar Imaging Satellite (RISAT-1) from the spaceport at Sriharikota at 5.45 a.m. on Thursday. The four stages of the Polar Satellite Launch Vehicle (PSLV-XL) have been stacked up at the first launch-pad built on the beachside on the Sriharikota island and the satellite is married up with the vehicle. The 71-hour countdown for the lift-off will begin at 6.45 a.m. on Monday. The RISAT-1 is essentially a remote-sensing satellite.
