The Clementine project is a subprogram of SDI. It deals with the analysis of secret bases on the moon. (Luna is one of those bases).
(Alternative 3 was the recommendation by the Jason Society to exploit alien and conventional technology in order for a select few to leave the earth and establish colonies on the Moon and Mars).
As part of the Clementine Project and Alternative 3, equipment would have been sent to the moon to set up a mixed human-alien base, called Luna. Whiteout was the name used for this project to send equipment to the moon between 1959 and 1964.
