NASA astronaut Don Pettit has revealed his passion for growing potatoes in microgravity, named "Spudnik," using an improvised grow light terrarium and using Velcro to anchor the potato in place. Despite its unique appearance, the potato appears to have thrived on the International Space Station. This experiment could potentially have significant applications for future humans living in space. The author of "The Martian," Andy Weir's book/movie "The Martian," suggests that potatoes could be used as crucial nutrition sources for future astronauts on long spaceflights or planets like Mars.
