Mesmerizing nighttime cloud images

The Indian Space Research Organization (ISRO) will launch Geosynchronous Satellite Launch Vehicle GSLV-F05 carrying advanced weather satellite INSAT-3DR on September 8, 2016 at 1610 hours from Satish Dhawan Space Centre, Sriharikota. The previous launch by ISRO on Geosynchronous Satellite Launch Vehicle (GSLV) was of GSLV-D6 carrying communication satellite GSAT-6 on August 27, 2015.

GSLV-F05 flight is significant since it is the first operational flight of GSLV carrying indigenously developed Cryogenic Upper Stage (CUS). GSLV-F05/INSAT-3DR mission would launch the 2,211 kg advanced weather satellite INSAT-3DR into Geostationary Transfer Orbit (GTO). ISRO’s Master Control Facility at Hassan, Karnataka will take control of the satellite and perform the initial orbit raising manoeuvres and place it in circular Geostationary Orbit. The solar panels of the satellite will be deployed immediately after reaching the GTO.

The advanced weather satellite INSAT – 3D was launched by ISRO on July 26, 2013 from French Guiana.

The satellite possessed an atmospheric sounding system, which allowed it to map vertical changes of humidity, temperature and ozone content in Earth’s atmosphere. The INSAT-3DR will be capable of making the same measurements – as well as better image night-time clouds, and better measure sea surface temperature. And like 3D, the 3DR will also include a search-and-rescue transponder, used to pinpoint the location of distressed vessels at sea.

The 3D will operate until 2021. The 3DR will last till around 2024.

Each launch will make ISRO more confident and self-sufficient in terms of launch capabilities.
