"Spudnik-1": An Orbiting Potato | International Space Station

Expedition 71/72 flight engineer and NASA astronaut Don Pettit: "I flew potatoes on Expedition 72 for my space garden, an activity I did in my off-duty time. This is an early purple potato, complete with spot of hook Velcro to anchor it in my improvised grow light terrarium."

"Potatoes are one of the most efficient plants based on edible nutrition to total plant mass (including roots). Recognized by Andy Weir in his book/movie 'The Martian,' potatoes will have a place in future exploration of space. So, I thought it good to get started now!"

Sputnik 1, often referred to as simply Sputnik, was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on October 4, 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries became depleted. Aerodynamic drag caused it to fall back into the atmosphere on January 4, 1958.

It was a polished metal sphere 58 cm (23 in) in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth.

NASA astronaut Don Pettit returned to Earth on April 19, 2025, concluding a seven-month science mission aboard the International Space Station. Pettit spent 220 days in space, earning him a total of 590 days in space over the course of his four spaceflights. He orbited the Earth 3,520 times, traveling 93.3 million miles in low-Earth orbit.
