An orrery was constructed for NASA/JPL by Pre-Mec Engineering, Inc. and was designed by JPL engineer Raymond A. McCreary (Design Part, 356 – a part of the Engineering Mechanics Division).
The dimensions of Earth and its moon was roughly 1 cm = 6000 km, however the scale of orbits, the Solar, and different moons diverse.
Pc animations didn’t exist within the early Nineteen Sixties, and like a trajectory mannequin, this orrery helped engineers plan, visualize, and exhibit the anticipated flight path, flyby, or touchdown to be made by a spacecraft. Missions in improvement right now had been Ranger and Surveyor (lunar missions), Mariner 2 to Venus, and Mariner 4 to Mars.
