Although Houbolt did not invent the idea of LOR, he was the person most responsible for pushing it at NASA. On July 11, 1962, Seamans and NASA Administrator James Webb announced during a press conference that LOR had been chosen as the primary mission mode for manned moon landing. ..Image # : L-1962-05848
