The PSLV-C19, the newest in the series of polar satellite launch
vehicles of the Indian Space Research Organisation (ISRO), burst off
the launch-pads of Sriharikota in the wee hours of Thursday on its
space mission of placing indigenously developed Radar Imaging
Satellite the RISAT-1 in a polar circular orbit.
After a customarily tense countdown at the ISRO's Satish Dhawan Space
Centre in Sriharikota, at precisely 5.47 a.m., the launch vehicle's
core stage igniters and set of six strap-on motors ignited within
seconds of each to signal the successful lift-off of the PSLV-C19 with
the RISAT -1 firmly docked inside its metal frames.
The RISAT-1 with a payload of 1858 kg, the heaviest satellite being
launched yet by the PSLV, is a state-of-the-art Active Microwave
Remote Sensing Satellite carrying a Synthetic Aperture Radar (SAR)
payload that will operate in the C-band. In simpler terms, the RISAT-1
can beam back imaging of the earth surface features during day and
night and under all imagined weather conditions. The SAR which gives
the RISAT-1 its magic lens also makes it superior to the generation of
optical remote sensing satellites in terms of clearer imaging at all
times and under any condition.
Once the PSLV-C19 successfully completed each of the four stages of
its flight in a span of 18 minutes and reported normal parameters,
congratulatory scenes broke out at the Mission Directorate at
Sriharikota.
Addressing the team of scientists and engineers, ISRO Chairman K.
Radhakrishnan said he was happy to announce that the PSLV-C19 was a
"grand success" and had injected into polar orbit India's first Radar
Imaging Satellite. Prof. Radhakrishnan also laid out the roadmap of
PSLV launches during the year ahead and the stated that the ground
tests of the GSLV driven by indigenous cryogenic technology had been
promising and was scheduled completion in September-October this year.
Prof. Yashpal and Prof. U.R. Rao, two of ISRO's founding fathers were
also present to partake in the celebrations of what they described as
a landmark event.
