He played a role in the advent of the space program

Peter planned a weekend retreat for rocket enthusiasts not long after finishing The Spirit of St. Louis. To discuss reusable rockets and a personal route to space, he invited scientists, financiers, engineers, and space enthusiasts.

Charles Lindbergh was also a well-known supporter of early aviation. Via his collaboration with Robert Goddard, the so-called "father of modern rocketry," he also contributed to planting the seeds of the space program. In late 1929, Lindbergh first became aware of Goddard's research on liquid-fueled rockets, and the two quickly grew close. In 1930, Lindbergh assisted Goddard in obtaining an endowment from Daniel Guggenheim, enabling Goddard to increase his research and development. Lindbergh remained a significant supporter of Goddard's efforts throughout his life.

Charles Lindbergh became Goddard's greatest supporter after becoming convinced that his work may one day make it possible to travel to the moon. He even persuaded millionaire Daniel Guggenheim to give the physicist $100,000 in funding. The innovations made by Goddard would subsequently be crucial to the creation of early missiles and space exploration. "You have made Robert Goddard's dream a reality", Lindbergh wrote in a letter to the astronauts after Apollo 8 became the first manned space mission to orbit the moon in 1968.
