ESA astronaut André Kuipers during the DELTA Mission on board the International Space Station in April 2004. Kuipers is wearing the SUIT experiment vest. The aim of the SUIT project is to support the astronaut with a vibrotactile suit to help with orientation in space. This suit consists of numerous small vibrating elements covering the torso. These elements inform the astronaut of a given predefined direction within the ISS by vibrating in that direction.
