Scientists at the Indian Space Research Organisation (Isro) launched the GSLV-F05, carrying advanced weather satellite INSAT-3DR, after a delay of 40 minutes. The launch was rescheduled as there was a "delay in cryostage filling operations" and it was rescheduled to 4.50 pm.
Earlier, it was scheduled to lift off by 4.10 pm from the second launch pad at this spaceport. "Yes. It has been delayed by 40 minutes. Why, because, due to delay in cryostage filling operations, the launch is rescheduled to 4.50 pm," an Isro official told PTI.
Another official said, it may not be an "anomaly" but may be as a precautionary measure, it has been revised to 4.50 pm. On Wednesday, soon after the Mission Readiness Review committee and Launch Authorisation Board gave its clearance, the 29-hour countdown began at 1110 hours for the launch.
GSLV-F05 is significant since it is the first operational flight of GSLV carrying the indigeneous Cryogenic Upper Stage. Earlier with similar configurations, GSLV flights successfully launched the D5 and D6 missions in January 2014 and August 2015, putting the GSAT-14 and GSAT-6 satellites in the intended Geosynchronous Transfer Orbits "very accurately."
Doordarshan was airing the launch live from the space station in Sriharikota. You can watch the live telecast here:
