Participation in Mega Science Projects by Indian scientists has always been planned after careful nation-wide consultations. These consultations have come to be known as Mega Science Vision (MSV) Exercises. The last such Mega Science Vision Exercise was undertaken in 2014. 

The next Mega Science Vision-2035 (MSV-2035) Exercise has been undertaken by the Office of the Principal Scientific Adviser to the GOI.  The Year 2035 has been chosen keeping in view the timelines of similar exercises undertaken elsewhere in the world and the expected lifetime of utilization of major global facilities in which India is involved at the present time. The MSV-2035 Exercise has begun in the right earnest and will result in Road-Map Documents in six areas after widespread national stakeholder consultations. These six areas are: High Energy Physics, Nuclear Physics, Astronomy & Astrophysics, Accelerator-based Science & Technology, Climate Research and Ecology & Environmental Science.
