Inspiring culture and technology

In 1962, Oberon Zell-Ravenheart (then still using his birth name, Tim Zell) founded the Church of All Worlds, a Neopagan religious organization modeled in many ways (including its name) after the treatment of religion in the novel Stranger in a Strange Land. This spiritual path included several ideas from the book, including non-mainstream family structures, social libertarianism, water-sharing rituals, an acceptance of all religious paths by a single tradition, and the use of several terms such as "grok", "Thou art God", and "Never Thirst". Though Heinlein was neither a member nor a promoter of the Church, there was a frequent exchange of correspondence between Zell and Heinlein, and he was a paid subscriber to their magazine, Green Egg. This Church still exists as a 501(C)(3) religious organization incorporated in California, with membership worldwide, and it remains an active part of the neopagan community today. Zell-Ravenheart's wife, Morning Glory coined the term polyamory in 1990, another movement that includes Heinlein concepts among its roots.

Heinlein was influential in making space exploration seem to the public more like a practical possibility. His stories in publications such as The Saturday Evening Post took a matter-of-fact approach to their outer-space setting, rather than the "gee whiz" tone that had previously been common. The documentary-like film Destination Moon advocated a Space Race with an unspecified foreign power almost a decade before such an idea became commonplace, and was promoted by an unprecedented publicity campaign in print publications. Many of the astronauts and others working in the U.S. space program grew up on a diet of the Heinlein juveniles, best evidenced by the naming of a crater on Mars after him, and a tribute interspersed by the Apollo 15 astronauts into their radio conversations while on the moon.

Heinlein was also a guest commentator (along with fellow SF author Arthur C. Clarke) for Walter Cronkite 's coverage of the Apollo 11 Moon landing. He remarked to Cronkite during the landing that, "This is the greatest event in human history, up to this time. This is—today is New Year's Day of the Year One."

Heinlein has inspired many transformational figures in business and technology including Lee Felsenstein, the designer of the first mass-produced portable computer, Marc Andreessen, co-author of the first widely-used web browser, and Elon Musk, CEO of Tesla and founder of SpaceX.
