Scripting success on the maiden operational flight of its heavy-duty rocket fitted with the indigenous cryogenic upper stage, India today launched its advanced weather satellite INSAT-3DR onboard GSLV-F05 from the spaceport here.
The 49.13-metre tall rocket lifted off from the second launch pad at the Satish Dhawan Space Centre here at 4.50 PM, majestically soared into the skies and injected the 2,211-kg INSAT-3DR into a Geosynchronous Transfer Orbit about 17 minutes later.
Earlier, it was scheduled to lift off by 4.10 PM but due to “delay in cryostage filling operations” it was rescheduled to 4.50 PM, officials said.
INSAT-3DR, with a designed mission life of ten years, will provide service continuity to earlier meteorological missions and further augment the capability to provide various meteorological, search and rescue services.
Today’s mission, the 10th flight of GSLV, assumes significance for the Indian Space Research Organisation (ISRO) as it is the first operational flight of the rocket fitted with the indigenous cryogenic upper stage.
Earlier, GSLV launches with indigenous cryogenic stage were under ‘developmental’ phase.
GSLV-F05 also marked a hat-trick of success for the indigenously developed complex cryogenic upper stage (CUS) after GSLV-D5 (January 2014) and D6 (August 2015) missions, which had launched GSAT-14 and GSAT-6 satellites into precise orbit.
“Today’s launch of GSLV-F05 is significant since it is first operational flight of GSLV carrying Cryogenic Upper Stage. Earlier launches were developmental. The engine used was Russian engine. Today’s launch is indigenous Cryogenic Upper Stage and it is the first operational flight,” an ISRO official told news agencies.
The 2014 success had propelled India into the elite group of countries boasting of the homegrown complex cryogenic engine and stage after twin failures in 2010.
A jubilant ISRO Chairman A S Kiran Kumar patted his team of scientists for “another achievement” even as he said the satellite was placed in the orbit.
P Kunhikrishnan, Director, Satish Dhawan Space Centre SHAR (SDSC SHAR), said today’s was a ‘precision launch’ where the satellite was placed in a “very accurate geosynchronous orbit.”
