India’s Polar Satellite Launch Vehicle (PSLV) rocket, is undoubtedly among the most successful and consistent rockets in the world among the sub-1.5ton payload to Low-earth orbit or polar orbits. But one lesser-known facet beyond the enviable success rate of this rocket, is its second-stage engine - Vikas. While a solid engine burns out after use, the liquid engine can be tested, re-used after cleaning and re-assembly. The 600kg thrust engine was minuscule compared to the giant 60ton engines(clustered in four to obtain 240ton thrust) that the Americans and Russians were using. However, the ‘obstinate Vikas Engine’, which was developed by Nambi Narayanan and his team had flown flawlessly in all 50 flights.
