We ate space mushrooms and survived to tell the tale
The Great Space Mushroom Experiment: A Journey to the Edge of Space and Back
In August 2024, a SpaceX Falcon 9 rocket launched 36 small vials into space, carrying three edible fungi species in the form of mycelium - small file filaments that act like the root network of mushrooms. The experiment, led by Swinburne University of Technology, aimed to study the effects of microgravity on these fungi and their potential use in long-duration space missions. The mycelium, consisting of lion's mane (Hericium erinaceus), turkey's tail (Trametes versicolor), and cordyceps (Cordyceps militaris), were sealed in special packaging to ensure their survival during the journey.
The Journey to Space
The fungi may have stayed on the International Space Station (ISS) with astronauts, but their experience was very different. Science experiments have special storage areas depending on what is being done and how much time astronauts have to be involved. Our mycelium was sealed up tight in special packaging to help keep them at a stable temperature and to ensure they weren't damaged. They stayed like that for close to a month, before they returned with the change of crew on the ISS.
The Return to Earth
When our mycelium returned to Earth, and eventually Australia, they got a new home in rich, nutritious substrate. We then moved it into grow kits so we could watch and see whether any fruiting bodies (that is, mushrooms) would appear. We created several grow boxes and placed them in different environments to see what conditions were best - from kitchen benches, to staff room tables, to laboratory fridges.
The Results
To our delight, within a few days we saw signs of the mushrooms emerging and within a week we had beautiful lion's mane ready to be cooked up and enjoyed. Once they were ready, we harvested them and tried different recipes. As well as eating these mushrooms, we're also in the process of analysing them closely. But we can say now that the reduced gravity environment did not negatively impact our mycelium. In fact, they seem to be so happy that they continued to produce several rounds of mushrooms.
Implications for Long-Duration Space Missions
Artemis II - NASA's crewed mission to the moon - is right around the corner. But there is still a lot that we need to understand to provide the best conditions for astronauts as they venture further into space than ever before. For example, how will we continue to nutritionally support astronauts for weeks to months on long-duration missions? We know that a low gravity environment has a profound impact on human bodies, and one of the best ways to support astronauts in orbit is with nutritional foods.
The Future of Space Food
Our work - and these special mushrooms - are helping to provide crucial answers. By studying the effects of microgravity on fungi, we can gain a better understanding of how to produce food in space environments. This is crucial for long-duration space missions, where the ability to produce food on demand is essential. The implications of this research are far-reaching, and could potentially lead to a new era of space exploration.
Conclusion
The Great Space Mushroom Experiment has shown that fungi can thrive in microgravity environments, and that they can be used to produce food in space. This research has significant implications for long-duration space missions, and could potentially lead to a new era of space exploration. As we continue to push the boundaries of space travel, it is essential that we consider the needs of our astronauts and the importance of providing them with nutritious food. The Great Space Mushroom Experiment is an important step towards achieving this goal.
