This article presents India's vision for advancing Accelerator Science and Technology and Applications (ASTA) through the Office of the Principal Scientific Adviser’s (OPSA) Mega Science Vision-2035 initiative, tracing the country's journey from its early accelerator research efforts to the development of world-class facilities and frontier technologies. It highlights the growing role of accelerators in particle and nuclear physics, medical therapies, industrial processing, materials research, and space applications; while emphasizing the need for sustained investment, indigenous technology development, and global collaboration. The roadmap outlines key priorities, including next-generation synchrotron and free-electron laser facilities, neutron and rare-isotope research infrastructure, advanced medical and industrial accelerators, and accelerator-driven energy systems. Written by Dr Vinit Kumar, the article underscores the importance of deeper industry participation, skilled workforce development, academia–laboratory partnerships, and robust implementation frameworks to build global competitiveness. Together, these efforts position accelerator science and technology as a strategic enabler of India's scientific leadership, technological self-reliance, industrial growth, and the vision of Viksit Bharat 2047.
