ISRO planned to test launch GSLV-Mk III-D1
ISRO is planned to launch GSLV-MK III-D1 rocket launching vehicle with capacity to launch four-tonne class of satellites from Sriharikota next month which will reduce dependency on International launching vehicles.
ISRO currently has capability to launch up to 2.2 tonnes of satellites by its launching vehicle. GSLV-MK III-D1 rocket launching vehicle will help to launch 4 tonnes of satellites in orbit.
- 'GSLV Mark III launch vehicle is capable of launching 4 ton satellites in geostationary orbit.
- GSLV MK III will carry GSAT -19 satellite which has mass of 3200 kg which planned to carry Ka and Ku band payload along with Geostationary Radiation Spectrometer (GRASP) payload to monitor and study the nature of the charged particles and influence of space radiation on spacecraft and electronic components. .
- GSLV MK III` consists of 2 solid strap on motors, one earth storable liquid core stage and the upper cryogenic stage- C25.
About Cryogenic Engine:
'Cryogenic is the study of substances at very low temperature in which gases like nitrogen, hydrogen and oxygen become liquid at minus 150 degree or less.
'This is the reason we called this as cryogenics engine, which use liquid hydrogen and oxygen as fuel that are stored at minus 253 degrees and then ignited to burn at plus hundreds of degrees centigrade .
'Cryogenic Engine was first used by US in 1963. India took almost 20 years to develop Cryogenic Engine.
