""Now in order to get from one place to another, something must move," Laurie Anderson reminded us in 1984. At this stage, Pioneer 10 had already been moving away from us for twelve years. In June 1983 it had moved past Neptune and became the first human-made object to move out of our solar system. Linda Sagan drew two human figures that were applied to the gold-anodized aluminium plaques fixed to both the Pioneer 10 and 11 probes. The male figure is depicted with a raised arm in an ambiguous gesture. As I move into the gallery space, the sound of bubbling water and garbled voices echo. On the display-tables are the artefacts of journeys and experiments taken and conducted in the past, or at least before I arrived."
