This refers to ‘ISRO launches GSLV-D5, puts India in cryogenic club’ (IE, January 6). Kudos to all the Indian scientists associated with ISRO. Their perseverance has won laurels for India, making it the sixth nation in the world to master the technology of developing cryogenic engines. It is heartening that the GSAT-14, India’s communication satellite, was successfully placed in the orbit by the GSLV-D5. It marks a historic beginning for 2014. This success could also boost skill development and become a source of constant encouragement for the scientists of our space research programme. Finally, our success with developing a cryogenic engine could go a long way in saving precious foreign exchange.
