John-David Bartoe became having none of it.
A payload specialist aboard a 1985 flight of the home shuttle Challenger, Bartoe sequestered himself a long way flung from his six crewmates. He became gratified to be on his first mission and even happier to glean made it safely into home after what became the home shuttle program’s first and completely abort-to-orbit, but changing into one of many first astronauts to drink Coca-Cola or Pepsi off Earth became a sip too a long way.
“I believed it became frivolous and detracting from the science of the mission. I didn’t be pleased it all,” said Bartoe, reflecting 35 years later on what the media dubbed then the “home cola wars.” “I said, ‘I’m now not going to develop it, I be pleased it it be a terrible thought.'”
So whereas his STS-51F crewmates took turns finding out out both Coke’s or Pepsi’s soda cans developed for use in home, Bartoe stayed apart.
“In retrospect,” he instructed collectSPACE.com in a newest interview, “that became in actuality a dead element for me to develop.”

Carbonated beverage container analysis
Coca-Cola became the first to system NASA about finding out a soda dispenser aboard the home shuttle.
Given the system that liquids can behave in the microgravity ambiance of Earth orbit, launching off-the-shelf soda cans or bottles would now not work. A mechanism is predominant to push or extract the liquid out of the container, but completely when desired by the astronaut to guide determined of constructing a enormous quantity of the cabin.
Coca-Cola invested a couple of quarter of one million dollars to adapt what regarded be pleased one of its aluminum cans to retain a laminated plastic obtain stuffed with soda and a carbon dioxide-pressurized bladder to propel the drink out. The can became topped with a steel valve and a ingesting spout.
When Pepsi bought note that Coca-Cola became going to home, it appealed to NASA to be included on the mission, as smartly. The company agreed, but completely if Pepsi could safe and lift a dispenser in time.
For its can, Pepsi modified an existing arrangement that it said on the origin cost $14 million to safe. Comparable to the dispensers archaic to bundle spray cheese or whipped cream, Pepsi’s home could moreover archaic a carbon dioxide-filled pouch to push the soda out, but in desire to being pre-pressurized, it employed chemicals to put the gasoline.

“This began out as a in actuality severe learn mission for the Coca-Cola company. They desired to glimpse if they may safe a can that will dispense a carbonated beverage in home lovely as for these who had been ingesting it right here on the ground. So that they put their engineers to work and came up with this high-tech can,” Bartoe said. “The Pepsi can became made remaining minute in a gargantuan bustle. It became now not virtually as high tech and became more be pleased a whipped cream can with somewhat white tab tipped sideways.”
NASA, trying to glean to downplay the commercial nature of the payload, referred to the Coke and Pepsi cans because the “Carbonated Beverage Container Overview” (CBCE) and relegated the process to at any time when the crew had time between what became the predominant center of attention of the STS-51F mission, advancing the look of solar, atmospheric and astro-physics.
Divide and dispense
“There became some reluctance on the a part of the crew, because of it seemed so commercial,” said Tony England, who be pleased Bartoe became on his first and completely home mission as a member of the STS-51F crew. “It wasn’t in actuality till we recast it as ‘Carry out we use carbonated drinks?’ that it seemed be pleased an inexpensive put a question to.”
Forward of the launch, four of every company’s cans had been packed aboard the shuttle and NASA and the astronauts agreed to a couple of ideas. To originate up, the crew would limit any opinions to how the cans functioned and steer determined of commenting on the drinks interior.
The astronauts — and more importantly, Coca-Cola and Pepsi — desired to preserve determined of any questions about which tasted greater.
Gordon Fullerton, the mission’s commander, determined that the top system to limit the crew’s involvement could be to glean completely Bartoe and Loren Acton, the flight’s other payload specialist, drink from the cans.
But Bartoe did now not want to be any a part of it.
“He may glean put my alternate [crew member] on board factual there at that moment, but he went off and in point of fact apt it,” said Bartoe, recalling Fullerton’s reaction. “He said, ‘K, recent thought: every person is going to drink — except for John. Three of us will drink Pepsi and three will drink the Coke.'”
So when it came time to drink, Bartoe became “banned to the flight deck,” Fullerton, England and mission specialist Fable Musgrave tried out the Coke and Acton, pilot Roy Bridges and mission specialist Karl Henize drank the Pepsi.
All gassed up and nowhere to jog
The STS-51F crew held the outcomes of the carbonated beverage container analysis non-public till their first publish-flight press convention on Aug. 14, 1985, a week after they had landed help on Earth.
The astronauts knew before they launched that the soda became going to be at room temperature. The eight cans had been loaded onto Challenger chilled, but without a refrigerator on board, there became no system to help them cold.
The temperature became now not a scenario.
“The taste became surprisingly, or possibly now not surprisingly, as that you just can search recordsdata from. It became a sexy taste. There became nothing pass with that,” England instructed collectSPACE.
The cans, themselves, also perceived to work as supposed.
“Both cans perceived to work horny,” said England. “When we opened them, they didn’t explode or the rest of that kind. And the drink became directly in the market upon trying to drink.”
The Pepsi can dispensed a more frothy liquid, though, which led to the astronauts taking part in with fizzy Pepsi balls.
The foremost insist became the beverage being evaluated, said England, and its skill to follow it “wet burps.”
“The scenario became with carbonated drinks. Can glean to you originate a bottle on Earth, the bubbles arrive up they in most cases jog away. Effectively, as that you just can imagine, if there may be no gravity, the bubbles develop now not arrive up,” he said. “So right here you are with his belly stuffed with carbonated beverage, with the gasses more or less with ease staying there.”
Can response
Coca-Cola declared first keep in the initial “home cola warfare,” in accordance to the crew having tested its can before Pepsi’s. “Coca-Cola, the first preference in refreshment around the arena, is now the first soft drink tasted in home,” the corporate said in an advertisement on the time.
Both companies partnered with tutorial groups to glean an supreme time their drinks’ first launch. Pepsi produced replicas of its home can that promoted the Young Astronauts group, whereas Coca-Cola licensed U.S. Space Camp to sell a plastic version of its dispenser. Coca-Cola also proficient its distributors and museums with duplicates of its can.
NASA equipped the Smithsonian Nationwide Air and Space Museum with examples of both the Coca-Cola and Pepsi cans, which went on expose in Washington, D.C.
Pepsi’s home can did now not flee all all over again, though the corporate did launch an oversize inflatable can (of the vogue archaic on Earth) to film a commercial aboard the Russian home residing Mir in 1996.
Coca-Cola persisted looking out to safe a drink for the astronauts. In 1991, it flew its STS-51F-vogue can to Mir to identical results. The company then changed its system, launching two versions of a allotting machine (“Fluids Generic Bioprocessing Equipment”), which is probably going to be archaic to dangle both a pressurized cup or bottle with a substitute of diversified Coca-Cola carbonated drinks, on STS-63 in 1995 and STS-77 the following year.
Since then, Coca-Cola has remained on Earth.
“I wonder if they may be horny in the one-sixth G on the moon or one-third G on Mars,” said Bartoe, who has embraced the cost of the STS-51F experiment in the 35 years since. “It is most likely you’ll develop some experiments on the home residing to attempt to resolve that out — for these who in actuality cared that powerful about having a soda in home.”
