What else can human waste be used for on Mars? 🤔

A team from Spanish technological center Tekniker is developing a new sustainable life support mechanisms, required to help astronauts live on Mars for long periods. converts astronaut wastewater and carbon dioxide from Mars' atmosphere into fuel using sunlight. Wastewater combined with CO2 makes rocket propellant

The project was initiated by ESA's Open Space Innovation Platform, which is helping to develop promising new innovations for space. It joins a host of other projects developed to help future astronauts maintain an off-world presence. "We aim to make the first reactor to produce space propellant on Mars using the planet's air, which is 95 percent carbon dioxide," Borja Pozo from Tekniker explained in a post."The reactor will be powered by sunlight, and astronauts' greywater will be used to help in the production of the propellant."

The Tekniker system relies on high-efficiency catalytic materials that produce hydrocarbons from atmospheric carbon dioxide mixed with wastewater. The process also detoxifies the wastewater, meaning it can be used as a recycling method. "The outcome of this activity could provide ESA with valuable input on the production of propellant on Mars or to power remote sites like ground stations on Earth," said Jean-Christophe Berton, ESA technical officer for the project"It could also potentially provide input on how to decarbonize our own atmosphere."It is one of many proposed systems to help Mars astronauts maximize their resources on Mars when they eventually reach the red planet.
