NASA’s tournament lab and HeroX’s newly launched “Waste to Base” challenge is looking for suggestions on how to “recycle, repurpose, or reprocess” waste material—specifically trash, fecal waste, foam packaging material, and carbon dioxide—during a two to three year mission to the Red Planet.

“The challenge is looking for your ideas for how to convert different waste streams into propellant, and into useful materials, that can then be made into needed things and cycled through multiple times.

Just head to the Waste to Base Materials Challenge: Sustainable Reprocessing in Space page, log in, and show those rocket scientists who’s a real genius.

NASA has no set date for a Mars mission—it’s more of a hope at this point—but they are running a Mars simulation on Earth (and looking for qualified people to join it), and speculate we might be ready to rock by 2037.
