Like Batman and the Joker, or the Red Sox and the Yankees, the rivalry between the Air Force and the Navy is long and complicated. The highly-influential Air Force pilot Col. John Boyd said in 1969, “We don’t care what the Russians are doing. We only care about what the Navy is doing,” which summarizes how the two services have battled over airpower funding and fighter aircraft designs for decades. 

But any rivalry can be put to rest with a little Christmas spirit, especially when you’re isolated in the cold vacuum of space. And that, dear reader, is how the first song was ever performed live in outer space, according to The Smithsonian.

A little more than 56 years ago, on Dec. 16, 1965, an Air Force pilot named Thomas Stafford and a Navy pilot named Wally Schirra played the Christmas anthem ‘Jingle Bells’ on a harmonica and miniature sleigh bells just before re-entering Earth’s atmosphere.

Gemini VI Jingle Bells

On this day (#OTD) December 16, 1965, Gemini VI astronauts Tom Stafford and Wally Schirra played a prank on Mission Control. Just before Gemini VI was set to reenter Earth's atmosphere, Stafford claimed to have received a mysterious radio signal. He said: "We have an object, looks like a satellite going from north to south, probably in polar orbit….very low, looks like he might be going to re-enter soon….Standby one, it looks like he’s trying to signal us.”Stafford and Schirra then burst into a performance of “Jingle Bells”, with Stafford on harmonica and Schirra on bells. It was the first song ever performed in outer space.Listen to the full transmission (and song) in the video below!

However, the song was performed not solely for peace on Earth and good will to men. No, the airman and sailor were bound together by the long military aviator tradition of trolling people on the ground.

For context: Stafford and Schirra had been sitting in a cramped space about the size of an economy-class airline seat for more than a day. They had just accomplished the first space rendezvous with their sister ship, Gemini 7, a maneuver that “required the most exacting pilot and computer control of a space vehicle yet attempted,” according to Smithsonian Magazine. Four days earlier, the two astronauts had nearly died after an engine malfunction almost destroyed their rocket on the launch pad.

“The crew was exceedingly lucky that the Titan [rocket] hadn’t actually taken flight,” said space flight historian Amy Shira Teitel in a 2015 video. “Had they even gotten a few inches off the launch pad when the engines shut down they would have fallen back down and it would have exploded.”

Stafford and Schirra had a second lucky break that day when they didn’t pull the D-ring that would have triggered their ejection seats. 

“Even though the system was designed for their safety it would have been a bit of a painful ride owing to the high-G forces,” Teitel said.

It also might have lit them up like “two Roman candles,” as Stafford recalled in a 1997 oral history for NASA, because the capsule was filled with highly-flammable pure oxygen. 

“It would have burned the suits,” Stafford said. “Everything was soaked in oxygen. So thank God.”

Close calls with sudden death are a routine occurrence for any military aviator. With that kind of weight in the background, it’s hard to blame them for having a little fun every once in a while. Maybe that’s why Stafford and Schirra smuggled their mini sleigh bells and harmonica into their cramped capsule. But before they performed, they had to work the crowd first.

The mission was to test the docking and maneuvering capability of the Gemini spacecraft. A few hours after the successful maneuvering of the the two spacecraft to within six inches of each other, the Gemini 6 astronauts played “Jingle Bells,” with Schirra on the harmonica and Stafford playing the bells.

While preparing to re-enter Earth’s atmosphere, Stafford reported seeing some kind of unidentified flying object.

“We have an object, looks like a satellite going from north to south, probably in a polar orbit,” Stafford told Mission Control in Houston, Texas. “Looks like he might be going to re-enter soon. Stand by one; it looks like he’s trying to signal us.”

Then the two astronauts picked up their instruments and scratched out the first live concert in space. They had come up with the plan weeks before the mission.

“Wally came up with the idea,” Stafford told the Smithsonian. “He could play the harmonica, and we practiced two or three times before we took off, but of course we didn’t tell the guys on the ground….We never considered singing, since I couldn’t carry a tune in a bushelbasket.”

Stafford could tell Mission Control was getting tense when he described an unknown object in orbit with them, but the mood was much lighter after he and Schirra played their song.

“You’re too much [Gemini] 6,” Mission Control said afterwards.
