In June 1965, the Directorate of R&D of the Future Weapons Office in Rock Island, Illinois published The Meanderings of a Weapon Oriented Mind When Applied in a Vacuum Such as the Moon:
The purpose of this brochure is to stimulate the thinking of weapon people all the way from those who are responsible for the establishment of requirements, through those who are responsible for funding, to the weapon designer himself.
“If space is truly for peace,” it reads, “we must be strong there just as we are on earth.”
It presents early thoughts and then corrected thinking, like this:
Although the widely advertised temperature of from –250° to +250° F. are actualities on the moon, they are the approximate extremes reached on the surface at midday and midnight. (Days and nights are two weeks long.) The surface of the moon is a poor conductor of heat, consequently a little shade during the day and earth light during the night, plus a reversible white and black umbrella may be sufficient to keep the temperature in the vicinity of the space suit within limits of from –65° to +125 to +160° F. Assuming a direct proportion to the reflecting area, earth light on the moon will be sixteen times greater than moonlight on the earth.
The discussion involves some calculations. A “5 to 95 percentile” man has an unrestricted maximum line of sight of from 1.4 to 1.6 miles on the moon, with its mean radius of 1080 miles:
Any object propelled horizontally from the shoulder of a man six feet tall (shoulder approximately 5 feet above the surface) would impact the surface after an uninterrupted flight of 2.73 times its velocity. For a velocity of 3000 ft/sec the impact point would be 8190 feet or about 2500 meters. [...] Therefore, the maximum range of a projected object at a velocity of 3000 ft/sec is about 320 miles when propelled at an angle of 45 degrees with the lunar surface. Its maximum ordinate is approximately 80 miles above the surface.
Orbital velocity at the moon’s surface is 5,600 feet per second — totally doable.
