The Space Explorer was of the rounded cab type and was similar to the Ocean Explorer except it was blue. Obviously by the nature of its work it didn't come with floatation devices and came with spare wheel sets instead, The immediate trailer came with a mechanical grabber. I don't have the Space Book so I'm lacking the proper names and designations of the trailers. Available types are the Radar Dome trailer, an Oxygen Capsule Carrier and a Mechanical Excavator trailer. I don't remember seeing much of these in BHS at the time, possibly because they had all been bought or maybe they just never stocked much.
