A RELOOK INTO THE HISTORICAL PROGRESS AND PHILOSOPHY OF INDIAN SPACE EXPLORATION

摘要

A study of the history and philosophy of the contribution of India towards the exploration of space since antiquity provides interesting insights. The contributions are described during the three periods namely (i) the ten millenniums from 10000 BC with a twilight period up to 900 AD, (ii) the ten centuries from 900 AD to 1900 AD, and (iii) the ten decades from 1900 AD to 2000 AD called mythological, medieval, and modern respectively. Some important events during the above periods provide a reference view of the progress. The Vedas during the mythological period and the Siddhantas during the medieval periods, which are based on astronomical observations, indicate that the Indian contributions preceded other cultures. But most western historians ignore this fact time and again in spite of many proofs provided to the contrary. This paper also shows that Indians had the proper scientific attitude of developing any physical theory through the triplet of mind, model, and measurements. It is this same triplet that forms the basis of the present day well known Kalman filter technique. Up to about 1500 BC the Indian contribution was leading but during foreign invasion and occupation it lagged and is improving only after independence.
