NASA says these 18 plants are the best at naturally filtering the air in your home

When it premiered in 1966, no one could have predicted that it would lead to more than a dozen spinoff shows, more than a dozen movies and one of the most enduring fandoms in popular culture.

“Star Trek” is also unusual for its close connections to NASA, both in its storylines and in the real world. Decades of “Star Trek” adventures have ignited a love of spaceflight across generations, inspiring many who now work as space professionals.

I’m a cultural anthropologist who studies why people work in space exploration. I’ve interviewed astronomers, engineers, flight surgeons and astronauts. Although I focus more on science fact than science fiction, I’ve noticed in my interviews how much the two threads intertwine.

Because of this, I found myself at a “Star Trek” convention in early August 2026, just ahead of the show’s 60th anniversary on Sept. 8. The convention participants included people of widely different ages, appearances and identities. I was struck by just how much those gathered reflected the series’ values.

When NASA met Star Trek

In the original series, the show’s creator, Gene Roddenberry, came up with a philosophy held by the Vulcan people. He called it IDIC: infinite diversity in infinite combinations. It suggests that an ideal society is made up of many different types, all working together.

It represented Roddenberry’s rejection of conformity. It also explained why the Enterprise crew included a Russian alongside Americans, and Black, Japanese and female characters all in positions of responsibility and authority. While many ordinary viewers absorbed “Star Trek’s” lessons of camaraderie and acceptance, those involved in real space exploration also took notice.

Roddenberry established relationships with NASA personnel in the early days of his series. NASA provided photographs of planetary bodies and advice about the realities of spaceflight, as well as stock footage and access to certain NASA facilities.

Leonard Nimoy, who played the popular character Mr. Spock, was even brought to the National Space Club’s Goddard Memorial Dinner in 1967 as a special guest. Then-Vice President Hubert Humphrey gave the keynote speech. Afterward, though, it was Nimoy, not Humphrey, who found himself surrounded by the club’s members, including NASA employees, aerospace engineers, members of the military and government officials, all eager to meet the actor portraying the starship Enterprise’s first officer.

The relationship between NASA and “Star Trek” benefited the show by legitimizing the series. It also helped NASA by publicizing its work and depicting a positive future where its efforts to land on the Moon would eventually lead to visits to distant worlds – and amazing scientific advances like the show’s transporter and warp drive.

The connection between the space show and space agency was reflected in NASA’s decision to name its first space shuttle Enterprise, after some encouragement from the “Star Trek” fan community.

Inspiring astronauts

In 1977, actress Nichelle Nichols, who portrayed communications officer Uhura, was hired to recruit for NASA. The space agency had expanded its pool of astronauts to include scientists and other “mission specialists.” For the first time, an astronaut no longer needed to be a pilot to participate in a space mission.

NASA selected its first Black astronaut candidates and its first female astronaut candidates in 1978. While this move toward inclusivity may not have been directly influenced by infinite diversity in infinite combinations, it was compatible with it. “Star Trek” inspired many of NASA’s future employees. In interviews for my book “The Ultraview Effect,” a quarter of the space professionals I spoke with mentioned “Star Trek” as an influence.

An Apollo astronaut I interviewed, for instance, said he believed humans would eventually “be able to go anywhere in the universe, just like ‘Star Trek.’”

A young engineer who had grown up in the 1990s told me his motivation came from the “opening line of ‘Star Trek’… to explore strange new worlds.”

A space shuttle mission specialist emphasized Roddenberry’s decision to make the starship crew multicultural, explaining: “Today I look at the diversity of it … he was setting the stage back when it wasn’t acceptable [in order] to be acceptable!”

A changing future

That influence has accompanied a changing astronaut corps.

Both the 2025 astronaut class, which for the first time included more women than men, and the crew of Artemis II, which sent the first woman, first Black astronaut and first Canadian on a lunar mission, resemble the future that “Star Trek” imagined.

The “Star Trek” fans at the convention I attended were even more diverse. It was clear to me that Roddenberry’s “infinite diversity in infinite combinations” isn’t just a concept from the series, but something that has become a defining value of contemporary Trek fandom.

One such fan, Bjo Trimble, holds special status. She is credited with “saving ‘Star Trek’” when the series was almost canceled in 1968 after two seasons. Wearing a rainbow “IDIC” pin, she signed autographs at the SyFy Sistas booth, where T-shirts featuring Black “Star Trek” icons such as Uhura and Benjamin Sisko were on display.

However, with the Trump administration’s recent orders to dismantle all of NASA’s diversity, equity, inclusion and accessibility programs and policies, institutional support for “Star Trek’s” vision of acceptance and inclusivity, which flourishes in its fan base, is being undone. This rollback occurred just as NASA’s crews were reaching new milestones in representing the diverse future that “Star Trek” has encouraged for decades.

Sixty years later, some of the diverse future that “Star Trek” imagined has become part of everyday spaceflight. Other parts of that ideal remain unfinished.
