The idea that mushrooms are from outer space may seem like something out of a science fiction novel, but there is biological reasoning to support this theory. Living mushroom spores have been found in every level of Earth's atmosphere, and they possess all the necessary requirements to travel on space currents. They can survive in the harsh conditions of space, such as high radiation and zero gravity, and their outer layer is metallic and purple, allowing them to deflect ultraviolet light. These unique characteristics have led some, like Terence McKenna, to suggest that mushrooms could be responsible for human intelligence and even human life on Earth. While this theory is yet to be proven, it has sparked interesting debates and could have implications for space exploration and our understanding of the universe.

The theory of panspermia suggests that fungal spores could have arrived on Earth via space debris
The theory of panspermia posits that microscopic life forms, such as bacteria, fungal spores, and other microbes, could be transferred between planets via space debris. This theory suggests that fungal spores may have arrived on Earth over a billion years ago through comets, asteroids, or other celestial bodies, and subsequently adapted to life on our planet. While this hypothesis remains unproven, it offers a potential explanation for the resilience of fungi in extraterrestrial environments.
Fungal spores exhibit unique characteristics that enhance their suitability for space travel. They can endure the harsh conditions of space, including high vacuum pressures and extremely low temperatures. The outer casing of a spore, distinguished by its metallic and purple hue, is one of the hardest and most electron-dense organic compounds found in nature. This structure enables the spore to deflect harmful ultraviolet radiation, further contributing to its durability in space.
The idea that mushrooms originated from space is intriguing, yet it represents a significant intellectual jump. Nevertheless, proponents of this theory, including Terence McKenna, have presented compelling arguments. McKenna suggested that mushroom spores possess the necessary attributes for interstellar travel and may have played a pivotal role in the evolution of human intelligence. He theorized that these spores settled in the brain matter of early hominins, potentially influencing the development of our modern cognitive abilities and self-awareness.
The exploration of fungi in the context of space travel extends beyond their hypothetical extraterrestrial origins. NASA, for instance, has shown a keen interest in studying fungi as part of its space exploration initiatives. Fungi are being examined for their potential contributions to sustainable space nutrition, interplanetary travel, and the development of innovative interstellar architecture. The resilience of fungi and their ability to thrive in extreme conditions, including high levels of radiation, make them valuable candidates for supporting human exploration and habitation in space.

Spores of mushrooms are well-suited to space travel and can survive in the vacuum of space
Mushrooms have unique growth habits, high nutritive value, therapeutic benefits, and the ability to withstand extreme environments. These characteristics could prove essential for long-distance space travel. In fact, mushrooms seem to thrive in space, leading some to believe they are of extraterrestrial origin.
The theory that mushrooms are from space stems from the theory of panspermia, which poses the question: what if microscopic life forms, such as bacteria, fungal spores, and other microbes, could be transported through space and land on another planet? Panspermia suggests that fungal spores could have arrived on Earth over a billion years ago via comets, asteroids, or other space debris. This could explain why fungi adapt so well to the harsh conditions of space, including high radiation and zero gravity, which are detrimental to human bodies.
The first indication that mushrooms might be able to survive in space came in 1988 when the Russian space station Mir was attacked by what Soviet microbiologist Natalia Novikova described as an "aggressive space fungus." This rapidly growing web of fungal hyphae threatened windows and control panels and gradually ate away at the interior of the space station and a Soyuz transport vehicle.
Further evidence for the ability of fungal spores to survive in the vacuum of space comes from experiments conducted during the Gemini IX and XII missions in 1966. These experiments exposed spores of Penicillium roqueforti to outer space for 6.5 hours and found a surviving fraction of <2 × 10^-6. Additionally, covering the samples with a thin layer of aluminum caused a 3,000-fold increase in the survival rate, indicating that non-penetrating radiation was responsible for the inactivation of the test samples.
Mushroom spores possess unique characteristics that make them well-suited for space travel and survival in the vacuum of space. Their outer layer is electron-dense, metallic, and of a purple hue, allowing them to deflect ultraviolet light. Furthermore, their outer shell is the hardest organic compound found in nature, providing protection from the harsh conditions of space.

Terence McKenna's theory suggests that mushroom spores settled in the brains of primitive humanoids, contributing to human intelligence
Terence Kemp McKenna, an American ethnobotanist and mystic, popularized the use of plant-based psychedelics, particularly psilocybin mushrooms. He advocated for the responsible use of naturally occurring psychedelic plants and mushrooms, believing that they enabled access to profound visionary experiences, alternate dimensions, and communication with intelligent entities.
McKenna's theory suggests that psilocybin mushrooms may be a highly intelligent species that arrived on Earth as spores migrating through space. He proposed that these spores possess all the necessary requirements to travel on space currents and could have settled in the brains of primitive humanoids, contributing to our modern-day intelligence and self-awareness. At higher doses, he believed that psilocybin would trigger activity in the "language-forming region of the brain," leading to the emergence of language in early hominids.
McKenna's theory is a radical interpretation of biophysicist Francis Crick's hypothesis of directed panspermia. He speculated that intelligence, not life, may have come to Earth through spore-bearing life forms. He argued that mushroom spores could be blown from one star system to another by cosmic radiation pressure, and their potential for interstellar travel has yet to be fully appreciated.
While McKenna's ideas may seem like science fiction, mushrooms possess unique traits. For example, they build cell walls out of chitin, found in insect shells and some bird plumages. Additionally, living mushroom spores have been found at every level of Earth's atmosphere, and their outer layer is metallic and purple, allowing them to deflect ultraviolet light. These characteristics contribute to the intriguing possibility that mushrooms may have played a role in the development of human intelligence.

Mushrooms are being considered as a sustainable food source for astronauts due to their ease of growth and high yield
Mushrooms are being considered as a sustainable food source for astronauts due to their ease of growth, high yield, and nutritional value. Mushrooms are not plants but fungi, and they possess a unique set of biological properties that make them ideal for space exploration. Their spores are incredibly resilient, with the ability to survive in the vacuum of space and deflect ultraviolet light. This makes them well-suited to the challenging conditions of space travel, including high radiation and zero gravity, which can be dangerous for human astronauts.
The ease of growing mushrooms is another advantage. They don't require much space, time, or resources, and can thrive on organic waste, including food scraps and human waste, breaking it down and recycling it into compost that can be used to grow more crops. This closed-loop ecosystem is essential for efficient waste management on long space missions. Additionally, mushrooms are nutritionally dense, containing a wide array of nutrients typically found in vegetables, grains, nuts, seeds, and meat. They are a good source of folate, potassium, riboflavin, biotin, niacin, pantothenic acid, copper, selenium, and chromium.
The potential for mushrooms to support a circular economy is also promising. According to Flavia Fayet-Moore of Foodiq Global, a nutrition and research firm, "Not only can they help close that loop in plant agriculture... but when we are done growing mushrooms, that substrate is used to grow more plants. It creates a circular economy." Furthermore, mushroom compost, a common byproduct in terrestrial farming, can be used to turn agricultural and textile waste into something new.
The adaptability of mushrooms makes them ideal for controlled agricultural systems in space, where environmental conditions must be carefully managed. Their ability to generate vitamin D when exposed to UV light also provides significant health benefits for astronauts. In summary, mushrooms are being considered as a sustainable food source for astronauts due to their ease of growth, resilience, nutritional profile, and ability to support a circular economy, making them a key focus of research for space exploration.

While there is no evidence of mushrooms or any other life in space, NASA is studying fungi to develop protective coatings for spacecraft and electronic equipment used in space exploration.
Fungi are one of the first organisms to thrive in environments on Earth that experience nuclear activity and high levels of radiation. NASA aims to understand how radiation affects fungi and other microorganisms to develop strategies or medicines that protect astronauts from radiation harm. By studying how fungi respond to radiation, researchers can develop a protective coating for spacecraft and electronic equipment. This protective layer will be essential for future missions like Artemis II and Artemis III, where astronauts will explore and establish a sustainable presence in space.
NASA has conducted investigations, collectively known as Biological Experiment 01 (BioExpt-01), using model organisms aboard the Artemis I mission, an uncrewed test flight sent around the Moon. These investigations aim to understand how biological and physical phenomena, including microgravity, ionizing radiation, and altered atmosphere, impact fungi and other organisms.
Fungi have unique properties that make them ideal for space exploration. They can remain dormant during launch and travel to space, and then "activate" and reproduce in space stations. Additionally, their outer layer is metallic and purple, allowing them to deflect ultraviolet light. Understanding how fungi thrive in microgravity conditions will enable the development of lightweight structures on the Moon and Mars for future space habitation.
NASA's studies on fungi have broader implications for space exploration. Fungi could be used in space biomanufacturing to produce biomaterials, medicine, and food, eliminating the need to transport supplies from Earth. Furthermore, fungi can help develop technologies to create lightweight structures in space, and their natural protective qualities can be applied to protect humans from radiation during long-term space missions.
