Indigenous Cryogenic Engine Build by ISRO. ISRO has again gathered fame with a new milestone in space technology, with successful endurance test of an indigenously developed cryogenic engine. The engine was made to power up the most powerful rocket system, GSLV (Geosynchronous Satellite Launch Vehicle) MK-III. The engine went under 800 seconds of the test. The test stood longer for 25% more time than required for the space flight the engine operates with its propellant at a very low temperature, liquid hydrogen at 20 kelvin and liquid oxygen at 80 Kelvins. As per the sources, the test was 10th in the series of the development of a cryogenic engine. The production aims to increase the power of rocket system to four tonnes category spacecraft from current two plus tonnes category. Further high altitude tests are also planned for its clarification and final use. Earlier, the cold test and short term hot tests were conducted by ISRO.
India is among the 6 nations who have successfully tested and deployed. Japan, China, Russia, United States and European space agency are the previous rankers of the list.
What is Cryogenic Engine?
The engines are basically a reaction based mechanism that not works like any electric engine. The fuel is stored in the pressurized form. Normally, cryogenic engines are of two types i.e. liquid propellant engine and hybrid engine. The reason of converting the propellant to liquid is that the gaseous propellant will increase the fuel tank size and mass, making it difficult to lift. So the engine is kept at a cryogenic temperature and maintaining the liquidity of the propellant. It makes the engine more efficient and powerful.
Achievements of ISRO
GAGAN – GPS Aided Geo Augmented Navigation is intended to provide accurate navigation services over the Bay of Bengal, South East Asia, Indian Ocean, Middle East, and African regions. Well, it is efficient to fill the gap between European Union’s EGNOS and Japan’s MSAS.
IRNSS – India’s indigenously developed regional navigation satellite, which was built to give accurate navigation coordinated to the Indian users and users in the range of 1500km from its boundary. Developed by ISRO it is completely under the Indian government.  For positioning, the system will reduce dependency over GPS GLONASS etc.
Chandrayaan – As the name describes the motive, it is India’s first mission to the moon, launched by modified PSLV in October 2008 and put into orbit in November 2008. American institute of Aeronautics and Astronautics awarded it SPACE 2009 award. Space Pioneer prize was also awarded by national space society.
Mars Orbit Mission (Mangalyaan) – Honor to mention that India is the only nation to launch it in first attempt. It went into orbit in September 2014. It was named as one of the best inventions of 2014.
Conclusion
The India scientists have achieved their goal and ones again marked the name of ISRO, in the list of elite agencies. The space exploration and technological enhancement has led India to new heights. The motto of MAKE IN INDIA has a wide influence on all sectors and fields. The successive thrust of being self-reliant is on the zenith. The great minds along with the government-backed facilities described the efficiency of the scientist and designers.
