The narrative begins full throttle from the early days of rocketry at Thumba, a tiny fishing village close to the VSSC, after the initiatives triggered by participation of Indian scientists in the International Geophysical Year (IGY-1957-58) and the formation of the INCOSPAR in 1962. Thereafter, the author throws light on the exciting phases consisting of firing of rockets, building of small satellites, launch vehicles under the leadership of Vikram Sarabhai, Satish Dhawan to U.R. Rao in the first and most challenging phase till around 2000. The PSLVs, ASLV and GSLV were developed while the applications part from the Aryabhatta satellite to the SITE programme gathered pace. The programme took a giant leap in 2008, when the ISRO, under the chairmanship of Madhavan Nair, successfully sent the Chandrayaan-1 to the Moon. The Moon probe made a remarkable discovery of water molecules on the lunar surface. This was followed up by the Mars Orbiter Mission in 2014 and finally, the historic landing on the southern side of the Moon by Chandrayaan-3 in August-Sept 2023.
