Using 'waste' product from recent NASA research, scientists create transformative nanomaterials

Researchers at the University of Sussex have discovered the transformative potential of Martian nanomaterials, potentially opening the door to sustainable habitation on the red planet.

Using resources and techniques currently applied on the International Space Station and by NASA, Dr. Conor Boland, a Lecturer in Materials Physics at the University of Sussex, led a research group that investigated the potential of nanomaterials—incredibly tiny components thousands of times smaller than a —for clean energy production and on Mars.

Taking what was considered a by NASA and applying only sustainable production methods, including water-based chemistry and low-energy processes, the researchers have successfully identified within gypsum nanomaterials—opening the door to potential clean energy and sustainable technology production on Mars.

The research is published in the journal Advanced Functional Materials

Dr. Conor Boland, said, "This study shows that the potential is quite literally out of this world for nanomaterials. Our study builds off recent research performed by NASA and takes what was considered waste, essentially lumps of rock, and turns it into transformative nanomaterials for a range of applications, from creating clean hydrogen fuel to developing an electronic device similar to a transistor to creating an additive to textiles to increase their robustness.

"This opens avenues for sustainable technology—and building—on Mars but also highlights the broader potential for eco-friendly breakthroughs here on Earth."

To make the breakthrough, the researchers used NASA's innovative method for extracting water from Martian gypsum, which is dehydrated by the agency to get water for human consumption. This produces a byproduct called anhydrite—considered waste material by NASA but now shown to be hugely valuable.

The Sussex researchers processed anhydrite into nanobelts—essentially tagliatelle-shaped materials—demonstrating their potential to provide clean energy and sustainable electronics. Furthermore, at every step of their process, water could be continuously collected and recycled.

Dr. Boland added, "We are optimistic about the feasibility of this process on Mars, as it requires only naturally occurring materials—everything we used could, in theory, be replicated on the red planet. Arguably, this is the most important goal in making the Martian colony sustainable from the outset."

While full-scale electronics production may be impractical on Mars due to the lack of clean rooms and sterile conditions, the anhydrite nanobelts hold promise for clean energy production on Earth, and could, later down the line, still have a profound effect on production on Mars.
