NASA astronaut Don Pettit garnered attention for a peculiar experiment he conducted aboard the International Space Station (ISS): he cultivated a potato in the microgravity environment, naming it “Spudnik” (a portmanteau of “Spud” and “Sputnik,” as referenced in the “Friends” sitcom). Pettit stated his motivation was to observe how the tuber would behave in space, drawing inspiration from the plot of the book and film “The Martian,” where potatoes are crucial for survival on Mars.
According to the astronaut, for this trial, he assembled a makeshift miniature greenhouse complete with lighting and secured the potato using Velcro. The vegetable resided within a repurposed drink container. In weightlessness, its sprouts began to develop in an unusual manner: some segments stretched upwards instead of downwards, as they would on Earth—a phenomenon Pettit humorously dubbed “wrong roots.”
Although amusing, this anecdote carries genuine practical weight, as scientists view the potato as a promising crop for spaceflight: it offers good nutrition, is relatively hardy, and could be instrumental in developing food cultivation systems on the Moon, Mars, and in deep space.
“As highlighted in ‘The Martian,’ it [the potato] is a great source of sustenance and will likely be useful in future deep-space gardening endeavors. Perhaps one day potatoes will grow on Mars! For now, however, we are learning everything we can in low-Earth orbit,” Pettit commented on the Reddit forum.
