Construction toy playset, made from injection-moulded ABS bricks and components of various sizes, shapes and colours. The 'supply station' is mounted onto a grey base which has moulded 'crater' features. The base is a long platform supported by eight blue struts, its proper right is a 'landing pad' for the two small saucer-like spacecraft; the proper left is a control centre with a lifting canopy. At either end of the platform is an antenna dish. As well as the two saucers, there are two wheeled vehicles: one is articulated in the middle, the other has a storage box on the back. There are four astronaut minifigures: two with yellow spacesuits, two with red. With the object is its colour-printed paper building instructions.
