Project Horizon: An early study of a lunar outpost

Abstract This paper reviews Project Horizon, an ambitious proposal for the establishment of an outpost on the Moon undertaken at the end of the 1950 decade by the U.S. Army. Historically, it was a pioneering and carefully developed study of the myriad factors involved in travelling to and from the Moon and making possible the permanent presence of man on its surface. Among the many subjects considered are lunar outpost design and construction, scientific programs proposed to be undertaken on the Moon, launch and transfer vehicles, launch facilities and communications. Some background facts on Project Horizon are also described.
