grihalakshmi magazine Published this article page no 71 The GSLVF10EOS03 mission which lifted off from Sriharikota on August 12 last year failed due to deviation in the performance of the cryogenic upper stage (CUS) of the launch vehicle a nationallevel Failure Analysis Committee (FAC) constituted in the aftermath has found. GSLVF10 was ISROs eighth flight with indigenous cryo 14th GSLV flight and 79th launch from Sriharikota. What is EOS03? 1. EOS3 was the first stateofart agile Earth Observation Satellite which would have been placed in a geosynchronous orbit around the Earth. 2. It was expected to provide near realtime imaging which could be used for quick monitoring of natural disasters episodic events and any shortterm events. 3. The mission life of the satellite was 10 years. What is a GSLV Rocket? 1. The GSLV expands to a geosynchronous satellite launch vehicle. 2. The GSLV Mark II is the largest launch vehicle built by India. 3. As its name suggests it can launch satellites that will travel in orbits that are synchronous with the Earths orbit. 4. These satellites can weigh up to 2500 kg and are first launched into transfer orbits that have a distance from Earth of 170 km at closest approach and about 35975 km at furthest approach which is close to the height of the geosynchronous orbit. Difference between PSLV and GSLV India has two operational launchers Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV). 1. PSLV was developed to launch lowEarth Orbit satellites into polar and sun synchronous orbits. It has since proved its versatility by launching geosynchronous lunar and interplanetary spacecraft successfully. 2. On the other hand GSLV was developed to launch the heavier INSAT class of geosynchronous satellites into orbit. In its third and final stage GSLV uses the indigenously developed cryogenic upper stage. Geosynchronous vs Sun synchronous 1. When satellites are about 36000 km from the Earths surface they enter what is called the high Earth orbit. Here it orbits in sync with the Earths rotation creating the impression that the satellite is stationary over a single longitude. Such a satellite is said to be geosynchronous grihalakshmi magazine buy.
