A bizarre purple object with writhing tentacles floated inside the International Space Station and sent the internet into a frenzy this week. Social media lit up with alien egg theories and “kill it with fire” jokes. The truth came straight from the astronaut who grew it.
NASA astronaut Don Pettit grew the object during Expedition 72, which ran from September 2024 to April 2025. He returned to Earth on April 19, 2025. The veteran space flyer, on his fourth mission and a chemical engineer known for creative hands-on projects, worked on this in his off-duty time as a personal “space garden.”
He brought potato starts with him as personal items and nicknamed the result “Spudnik-1,” a play on the first satellite. The early purple potato variety features vibrant skin and flesh. Pettit anchored it with a small spot of hook Velcro inside an improvised grow light terrarium built from station supplies.
A tweet from X.
Pettit posted the full explanation himself on March 20, 2026. He wrote on X and Instagram: “Spudnik-1, an orbiting potato on @Space_Station! 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!”
Microgravity changes everything for plants. On Earth, gravity pulls roots down and shoots up. In space, roots spread in every direction at once. That random, chaotic growth created the eerie tentacle-like sprouts and egg-shaped look that freaked everyone out. The purple color made the effect even more striking.
@DramaAlert reposted the close-up images on March 25, 2026, framing it as a “freaky egg shaped growth.” Replies filled with alien invasion memes, xenomorph comparisons, and laughs. The visual confusion turned a simple sprouting potato into overnight internet gold.
Potatoes pack serious nutrition carbs, vitamin C, potassium in a compact package that stores well and yields plenty of edible food. NASA studies space crops like this to support long missions to Moon or Mars where resupply ships cannot reach crews. Pettit’s off-duty project fits right into years of work on systems such as the Veggie greenhouse already tested on the station. Fresh food in space also boosts crew morale on long trips.
A purple potato with wild roots turned into the week’s biggest space meme, but it also delivered a serious reminder. Everyday curiosity from astronauts like Don Pettit keeps pushing the science we need to live beyond Earth. One small Spudnik-1 could lead to big steps for future Mars gardens. Americans watching from home get to see that the final frontier still has room for backyard-style experiments and plenty of laughs along the way.
