In the mid-1990’s ISKCON scientist Sadaputa das (now deceased) of the Bhaktivedanta Institute was instrumental in designing the planetarium as well as various scientific exhibits for the TOVP project.
In this Srimad Bhagavatam lecture/video (3.29.6) from 1997 his genius and intelligence stand out as he explains the nature and purpose of some of the exhibits, as well as other scientific, archeological and historical facts. Please note that not all of the exhibit plans in this lecture may be in the current scheme.
