Where does Indian rocket technology come from? Self-reliance?

India's rocket technology mainly comes from the country's space program that began in the early 20th century. India's space exploration program can be traced back to the 1950s, when the country began to study rocket technology and missile development.

In 1960s, India began to study its own rocket technology, and successfully launched its first domestic rocket at 1963. Since then, India has continuously developed and improved rocket technology and gradually realized satellite launch and space missions.

India's rocket technology is mainly developed on the basis of self-reliance. Although India cooperated with the Soviet Union and other countries in the early days, it has been self-reliant in technology and capital, and achieved a space breakthrough through its own efforts.

In addition, India has actively carried out international cooperation, cooperated with many international organizations, shared technology and experience, and promoted the development of global space technology.
