Moonlight is an extraterrestrial light show that will be shown in the heavenly location of the Steentjeskerk in Eindhoven. A special project in collaboration with the national monument: the Dwingeloo radio telescope. Through “moonbounce” also called Earth-Moon-Earth communication, radio signals are sent from the radio telescope to the moon. In relation to this year’s theme “living colors”, tones are added to the radio signal, inspired by the famous melody from the Science-Fiction film Close Encounters of the Third Kind (Steven Spielberg, 1977). The radio signals that are sent to the moon, according to the tones, will be reflected back one by one after touching the irregular lunar surface (possibly including vestiges of 1969 astronaut Neil Armstrong’s footsteps and lunar landers!) And becoming “distorted” echoes observed by the radio telescope in Dwingeloo. The received signal is electronically converted to light. Thus, there is communication between our planet Earth and the moon by sending audio messages modulated on a radio signal and receiving light. The heavenly location of the Steentjeskerk is used to show “Moonlight”. An alien light show based on musical communication between planet Earth and the moon. The installation exhibits the communicative effect of the transmitted audio message and receiving the distorted response in light. In honor of the 100th anniversary of the Steentjeskerk and the 50th anniversary of the moon landing.
