After conquering low gravity and muttering something about giant leaps, Neil Armstrong and Edwin “Buzz” Aldrin sat down to a celebratory meal. Given the lack of champagne out in space, Spaceflight historian Amy Shira Teital revealed on Vintage Space that the first meal eaten on the moon consisted of bacon cubes.
[B]acon cubes were among the meals stored in the lunar module. And it worked out that meal A, the first scheduled meal to be eaten on the Moon, consisted of bacon squares, peaches, sugar cookie cubes, pineapple grapefruit drink and coffee. They ate history’s first meal on Moon slightly ahead of schedule after landing at the Sea of Tranquility.
However, if you're imagining two astronauts enjoying petite bacon bits on dainty crackers while gazing at Earth on the horizon, think not. These "bacon squares" were most likely dried up, meat-like salty treats that have since been replaced with freeze-dried sausage patties that are rehyrdrated with hot water. Not quite the same ring to it as #spacebacon.
