NASA astronaut Don Pettit has turned a small ISS experiment into a very space-age pun: he grew a potato in microgravity and named it ”Spudnik.” The setup nods straight at The Martian, where potatoes are the difference between dinner and disaster, and it also raises a real question: can a humble tuber help future crews feed themselves away from Earth?
Pettit says he improvised a tiny growing chamber with lighting and fastened the potato with Velcro, using a beverage container as the base. In weightlessness, the plant did not behave the way it would on Earth: some of the sprouts headed upward instead of down, which he joked were ”incorrect roots.” Space gardening, it turns out, has no interest in your botany textbooks.

Why potatoes keep coming up in space food plans
The joke lands because the underlying idea is serious. Potatoes are filling, adaptable, and relatively easy to grow, which is exactly why they keep showing up in conversations about food production on the Moon, Mars, and beyond. Other space crops have been tested for years, too, but potatoes remain a favorite because they pack calories without demanding a lot of drama from the grower.
Pettit’s own comment on Reddit pushed the point further: he said the crop could be useful in future deep-space gardening and that astronauts are learning as much as they can in low-Earth orbit first. That is the sensible bit hiding under the joke. Before anyone starts planning a Martian farm, someone has to figure out what grows, what bends, and what gives up the second gravity disappears.
What ”Spudnik” says about orbital farming
This kind of experiment is small, but it sits in a broader race to make space missions less dependent on Earth. If crews can grow even part of their food in orbit, the logistics get easier and the mission gets less fragile. The potato is not a full answer, but it is a useful test case – and, unlike many futuristic concepts, this one comes with dinner.
The next question is whether these tiny orbital gardens stay a novelty or become part of real life-support systems. If potatoes can tolerate microgravity, the argument for more ambitious crops gets stronger. If they cannot, ”Spudnik” will still have earned a place in the very small museum of space jokes that also teach science.
