India's journey to space has been a tale of determination, resilience, and innovation, propelling the Indian Space Research Organisation (ISRO) to worldwide recognition. The story began in the early 1960s when engineers faced immense challenges, even transporting rocket parts on bicycles due to limited resources. Despite the odds, ISRO was founded in 1969 under the visionary leadership of Vikram Sarabhai.

Initially, ISRO relied on foreign assistance, launching its first satellite, Aryabhata, in 1975 using a Soviet rocket. However, this reliance on foreign launch vehicles ignited a desire for self-reliance, prompting ISRO to develop its own rocket engines. The journey towards self-sufficiency began with the successful launch of the Rohini series of sounding rockets in 1979.

With the Cold War in full swing, India understood the importance of having its own launch vehicle for strategic independence. In the 1980s, the idea of creating a homegrown rocket took shape, and Indian engineers and scientists embarked on the challenging task of designing and building India's first space rocket.

ISRO's focus was on adapting and indigenously developing critical technologies, refining components, systems, and manufacturing processes to suit India's unique requirements. The integration of various subsystems and technologies was a key aspect of development.

Despite encountering some early failures, each mission provided valuable data, which led to improvements and a determination to succeed. The Polar Satellite Launch Vehicle (PSLV) was born as a result of this unwavering effort.

On September 20, 1993, PSLV's maiden flight faced an issue, but valuable data from the mission helped ISRO refine its approach. Subsequent flights, like PSLV-D2 and PSLV-D3, successfully placed satellites into polar orbits, showcasing India's space capabilities to the world.

On September 29, 1997, ISRO achieved a significant milestone with the first operational launch of PSLV, entirely developed in India. This marked India's entry as a space-faring nation, ushering in an era of innovation and space exploration.

With the recent successful launch of the Chandrayaan-3 mission to the Moon using its indigenous rocket, ISRO has further solidified its reliability and determination to explore the stars. Through perseverance and ingenuity, ISRO has become a name that commands respect globally, making India proud of its achievements in space research and technology.
