Moon rooms made of mushrooms could be the future of space habitat

Potential future inhabitants of the moon and Mars could live in rooms made of mushrooms. NASA is looking at the possibilities of fungi as a more sustainable option to metal and glass. 

NASA’s myco-architecture project is using mushrooms as the building blocks for its prototypes of how future space habitats could be built. The fungi would be able to grow around an already-established framework by just adding water. 

The project’s primary focus is on the underground threads that make up the main part of the fungus, known as mycelia. Mycelia are capable of growing, replicating, and repairing themselves, so it’s a potential solution to efficient space construction.

“Right now, traditional habitat designs for Mars are like a turtle — carrying our homes with us on our backs – a reliable plan, but with huge energy costs,” said Lynn Rothschild, the principal investigator of the project, in a press release. “Instead, we can harness mycelia to grow these habitats ourselves when we get there.”

The habitat would look like a three-layer dome, consisting of an outer layer of ice. The second layer would be made of cyanobacteria, which would use the sun shining through the ice and the water in the ice to photosynthesize. That layer would then produce oxygen for the final layer made up of the mycelia. 

While the project is in its early stages and focuses solely on space, scientists are also looking into whether or not these ‘shroom rooms could be used here on Earth. 

“When we design for space, we’re free to experiment with new ideas and materials with much more freedom than we would on Earth,” said Rothschild. “And after these prototypes are designed for other worlds, we can bring them back to ours.”

For instance, scientists have produced bricks made out of mycelium, yard waste, and wood chips. These materials would reduce the enormous carbon footprint of the construction industry if used instead of regular materials. 

And aside from using ‘shrooms as building blocks, NASA says there’s also the possibility to use these microorganisms to filter water and for humidity regulation. Mushrooms can even be used to produce electricity without using fossil fuels. 

We reached out to NASA to find out what the next stage of the myco-architecture project is, and we’ll update this story once we hear back.

NASA is looking to recruit private companies to help it collect up space resources for cold, hard cash. And it’s starting with a request for moon dirt and rocks.

“Today, we’re taking a critical step forward by releasing a solicitation for commercial companies to provide proposals for the collection of space resources,” Jim Bridenstine, NASA administrator, said in a blog post published Thursday. “When considering such proposals, we will require that all actions be taken in a transparent fashion, in full compliance with the Registration Convention, Article II and other provisions of the Outer Space Treaty, and all of our other international obligations. We are putting our policies into practice to fuel a new era of exploration and discovery that will benefit all of humanity.”

If you can find some clear skies this month and there's not too much light pollution around, how about taking a moment to enjoy some of the delights of that vast abyss above your head?

NASA has released a helpful video (below) explaining what to look out for in the night sky, and the best thing is that you don’t need any expensive kit to enjoy the view. While a pair of binoculars or a pricey telescope will certainly enhance what you see, many points of interest are visible to the naked eye.

Humans are returning to the moon in the near future, and we could be on our way to Mars before too long, as well.

But for missions aimed at creating bases where we can stay for extended periods of time, we need a way to harvest any available water for drinking, growing plants, or making rocket fuel.
