Marquardt Space Sled

A design for individual space maneuvering in the vicinity of a spacecraft, the space sled lost out to the seat-like maneuvering unit. The mannequin riding the sled is wearing an experimental space suit that was one of a series tested in the mid-1960s. Unlike the space sled, the suit was part of a continuing evolution which produced the operational space suits used today.
