The Indian Space Research Organisation (ISRO) launched a rocket carrying an advanced weather satellite today from the Satish Dhawan Space Centre at Sriharikota, a barrier island in the Bay of Bengal near the southern Indian state of Andhra Pradesh.
The launch was delayed by 40 minutes over an 'anamoly', ISRO said, according to media reports.
The GSLV-F05 rocket will carry the 2,211 kilogram satellite 'INSAT-3DR' and will be put in a geo-transfer orbit initially. It will then use its own propulsion systems to reach the geosynchronous orbit.
The satellite is fitted with modern equipment to study weather patterns and can help during search and rescue operations too.
This is India's tenth flight using the Geosynchronous Satellite Launch Vehicle (GSLV), which can send 2 to 2.5 tonne class of satellites in geostationary orbits.
The 'made in India' Cryogenic Upper Stage which is being carried on the rocket is being used for the fourth time. This will be the first operational flight carrying the cryogenic engine, the others were test flights.
Both test flight missions, one in January 2014 which launched the GSLV-D5 and another in August 2015 with the D6, were successful.
With today's launch, India will take a step forward, leaving the testing phase behind.
Here's what you need to know about the satellite:
- ?The INSAT-3DR is configured with an atmospheric sounder and an imaging system
- It is similar to the INSAT-3D, which was launched in 2013. The INSAT-3D changed India's weather monitoring system through its Atmospheric Sounding System.
- The Atmospheric Sounding system provided a vertical profile of temperature, humidity and integrated Ozone from surface to top of the atmosphere.
- INSAT-3DR has incorporated the many changes added to INSAT-3D:
- A middle infrared band with imaging provides night time pictures of low clouds and fog.
- Imaging in two Thermal Infrared bands to accurately estimate Sea Surface Temperature (SST).
- The Visible and Thermal Infrared bands have Higher Spatial Resolution.
- Carries a Data Relay Transponder which can be used to receive meteorological, hydrological and oceanographic data from remote locations. This will help during extreme weather-related disasters such as floods, droughts and cyclones.
- It also carries a Search and Rescue Transponder which receives signals when a distress beacon is sent from maritime, aviation and land-based users trying to contact the Indian Mission Control Centre.
- This will help the Indian Coast Guard, Airports Authority of India (AAI) and other organisations involved in search and rescue missions.
