LOR is first known to have been proposed in 1916 by Russian rocket theoretician Yuri Kondratyuk, as the most economical way of landing humans on the Moon.

The EOR proposal for Apollo consisted of using a series of small rockets half the size of a Saturn V to put different components of a spacecraft to go to the Moon in orbit around the Earth, then assemble them in orbit. Notes[edit]. The critical decision to use LOR was viewed as vital to ensuring that Man reached the Moon by the end of the decade as proposed by President John F.
