Seeing The Unseen: A public exhibition of Jupiter's interior  


We have demonstrated that simulation of Jupiter’s interior via physical computing can be achieved in public installations. Notably, the exhibition experience of using everyday technological devices, such as cell phone cameras to uncover invisible insights of the installation can help the general public have a better understanding of Juno’s scientific goal of revealing Jupiter’s interior. Importantly, by engaging the public through educational exhibitions, we can promote the mission and suggest interesting discussions about planet Jupiter that may indicate pathways for further research. Owing to the wide use of DIY physical computing in various types of installations, we anticipate that our exhibition project will provide powerful platform for the study of JPL’s public engagement and promoting JPL missions.

Having infrared lights submerged underneath the fog, originally, we planned to use a matrix of small infrared LEDs to generate pixelated visual effects. Our goal was to have the LEDs to flash in an organic form. However, due to the lack of brightness, we had to abandon this idea. Instead of distributing multiple infrared LEDs in the container, we chose to apply a small number of powerful bright infrared illuminators. As the size were relatively larger, the infrared devices were far heavier and harder to control. The ongoing research is a study of generating interesting movements of the infrared illuminators using I/O controllers and heavy-duty actuators, such as gear motors. Our belief is that the new version of infrared light effects can deliver more interesting experiences with the audience.

The development of the Jupiter’s interior installation is in the final stage of assembling. Our expectation of a successful public exhibition is very high and the application of physical computing will be a key factor for the outcome.
