The goal of the Tunis Science City is to disseminate science everywhere and to be active in regions even the remotest ones and to make science accessible to everyone. For this reason the Astro-bus of the Tunis Science City has visited many regions in Tunisia: Nabeul, Sousse, Mehdia…taking traveling exhibitions, mobile planetariums, and laboratories. In addition, the Astro-bus participated in the cultural and scientific caravan organized by the Constitutional Democratic Rally.
