Believe in yourself You will be successful. Believe in ISRO India will be successful. The Indian Space Research Organisation is now readying itself to jump to the next level. Once again putting everyone in a surprise. After the testing of Indegeneous Cryogenic Engines like CE 7.5, CE 20 and SCE 200. ISRO is putting them and their variants in use to make our larger dreams into reality. ISRO has taken up the challenge to develop Unified Launch Vehicle and Heavy Launch Vehicle. These new series of Rockets shows ISRO'S modular approach where the rockets can be customised to certain limits to make them capable for variety of space launch applications. The output of a cryogenic engine is pure H2O so we won't even be doing any pollution either. Here we introduce these two in a descriptive, balanced, interesting and easy to understand manner.
