Jay Barbree (November 26, 1933 – May 14, 2021) was an American correspondent for NBC News, focusing on space travel. He was the only journalist to have covered every non-commercial human space mission in the United States, beginning with the first American in space, Alan Shepard aboard Freedom 7 in 1961, continuing through to the last mission of the Space Shuttle, Atlantis's STS-135 mission in July 2011. He was present for all 135 Space Shuttle launches, and every crewed launch for the Mercury, Gemini, and Apollo eras. In all, he witnessed 166 human space launches.

Barbree grew up on his family's farm in Early County, Georgia, and entered the United States Air Force in 1950, when he was 16 years of age. Following the Air Force, Barbree began his broadcast journalism career at WALB in Albany, Georgia, where, in 1957, he saw Sputnik's spent booster rocket orbiting in the sky and then wrote radio and television reports about the Soviet Union's launch of the first artificial satellite.

Barbree was so interested in the space program that he paid for his ticket to get to Cape Canaveral in Florida in 1957 to watch the attempted Vanguard TV-3 launch. The failed launch was one Barbree did not forget: "There's ignition. We can see the flames", Barbree reported. "Vanguard's engine is lit and it's burning. But wait... wait a moment, there's... there's no liftoff! It appears to be crumbling in its own fire... It's burning on the pad... Vanguard has crumbled into flames. It failed ladies and gentlemen, Vanguard has failed".

Early the following year, he returned and witnessed the successful launch of Explorer 1 on January 31, 1958, all the while calling in his reports to WALB. Eventually, Barbree was hired by radio station WEZY in Cocoa Beach, Florida and worked as a traffic reporter, covering the space program as well.

Six months later, Barbree joined NBC as a part-time space program reporter, eventually moving to full-time. Over the years, Barbree had been offered the opportunity to move to Washington, D.C., or New York City, but he turned down every offer, preferring to stay and report on what had quickly become his passion, spaceflight: "This is a job where ... you have to be, whether you like it or not, a certain member of the space family".

In 1958, while in a restroom, Barbree overheard a general and a NASA official talking about an upcoming launch called "Project SCORE", one of the earliest American satellites. This would become one of Barbree's many scoops when after a bit of digging, he found that President Dwight D. Eisenhower would use the satellite to broadcast a pre-recorded Christmas message from outer space. When SCORE launched in 1958, Barbree broadcast the story, knowing the military would not deny it once the satellite was in space.

In the space program's early days, astronauts and reporters would often socialize in Cocoa Beach and had a very different relationship than they do today. Barbree described his relationship with the astronauts as a friend and confidant, often going out to dinner with them or socializing when they were in town. In his book, Barbree wrote that in 1961, Alan Shepard told him an "off the record" fact: he was going to be the first American astronaut in space. Barbree noted that if he were to report this, it would jeopardize the friendships and possibly his career, so he said nothing. Barbree also recounts a conversation with Gus Grissom about the astronaut's concerns regarding Apollo not long before the fatal Apollo 1 fire. Barbree's association with the astronauts had some unexpected bonuses as well: Neil Armstrong carried a gold coin to the Moon on Apollo 11 for Barbree, and Pete Conrad flew several flags and patches on Apollo 12, which Barbree later handed out to friends.

In the early 1980s, when NASA developed the Teacher in Space program, a similar initiative, Journalist in Space, was developed. Barbree was one of forty finalists to be selected as a Journalist in Space.
