ISS 'Alien Egg' Revealed as Space Potato
25 Mar
Summary
- An astronaut photographed a potato with tentacle-like sprouts on the ISS.
- The potato was part of an experiment for growing food in space.
- Space-grown potatoes grow slower and have roots that spread in all directions.
Astronaut Don Pettit, during Expedition 72 (September 23, 2024 – April 18, 2025), shared a striking photograph from the International Space Station (ISS). The image depicted a peculiar object with tentacle-like growths, initially sparking humorous comparisons to an alien egg. Pettit clarified that the object was an Early Purple potato, part of his personal "space garden" project conducted during his off-duty hours.
He explained that the potato was equipped with hook Velcro to secure it within an improvised grow light terrarium. Potatoes are recognized for their efficiency in providing edible nutrition relative to their mass, making them a key crop for future space exploration, as highlighted in "The Martian." Pettit observed that plants grown in orbit exhibit slower growth rates compared to Earth and their roots spread in all directions due to microgravity.
Astronauts have a history of cultivating various produce, including fruits, vegetables, and flowers, on the ISS. NASA aims to expand this effort by growing more tomatoes and peppers, and incorporating antioxidant-rich foods like berries for potential radiation protection. The ISS itself is a $100 billion orbiting laboratory, continuously staffed since November 2000 and serving as a platform for diverse scientific research.
