71-hour countdown commences for RISAT 1
"The countdown of radar sensing satellite RISAT-1 started today morning at 6.47 AM at Sriharikota. This is a 71- hour long countdown," an ISRO spokesman told PTI.
The launch is scheduled at 5.47 AM on April 26 from the Satish Dhawan Space Centre at Sriharikota in Andhra .
India currently depending images from a Canadian satellite as domestic remote sensing spacecraft cannot take pictures of the ground during cloud cover.
"This (Radar Imaging Satellite or RISAT-1) is about 1,850 kg. So this will be heaviest satellite lifted by a PSLV (Polar Satellite Launch Vehicle)," ISRO Chairman K Radhakrishnan had earlier said.
The approved cost of RISAT-1, including its development, is Rs 378 crore, while Rs 120 crore has been spent to build the rocket (PSLV-C19), making it a Rs 498-crore mission.
RISAT-1 will be launched into a 536-km orbit by PSLV, India's workhorse rocket.
The satellite carries a C-band Synthetic Aperture Radar (SAR) payload, operating in a multi-polarisation and multi-resolution mode to provide images with coarse, fine and high spatial resolutions.
