The 50 twigs in this installation point in unison in the direction of the oldest piece of human made space debris currently above the horizon. The debris being tracked are spent rocket bodies, parts from defunct satellites and wayward tools launched in missions as far back as 1958. When the piece of debris being tracked drops below the installation’s horizon the twigs go to a rested downward pointing position and await the next debris to appear. The composition is continually changing as it tracks the oldest discarded objects orbiting the earth that enter its point of view.
