NASA just opened a challenge seeking ways to go to Mars and back with a minimum of wasted materials.
The agency's tournament lab, along with crowdsourcing platform HeroX, have launched a "Waste to Base" challenge looking for ideas to recycle trash, waste, carbon dioxide and foam packaging materials during a two- to three-year crewed Red Planet mission.
Competitors have until March 15 to enter the challenge, and several prizes of up to $1,000 each will be awarded for novel ideas, out of a total purse of $24,000. The winner should be announced by April 22, according to the challenge website.

"This challenge is all about finding ways to convert waste into base materials and other useful things, like propellant or feedstock for 3D printing," the website stated.
"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. While a perfectly efficient cycle is unlikely, ideal solutions will result in little to no waste."
Full eligibility requirements are available on the contest website; generally speaking, anyone in the world 18 years of age or older may participate individually or as a team, as long as their jurisdiction is not under United States federal sanctions, HeroX said.
The winning ideas are expected to be put into a whitepaper as "part of the roadmap for future technology development work" for NASA's logistics reduction project, which is working on matters such as new spacecraft and future settlements, the challenge description noted.
While NASA hasn't yet set a firm timeline for putting humans on Mars, the agency speculated in recent years that it may be able to get there by the mid-2030s. In the shorter term, the agency is hoping to put Artemis astronauts on the moon by the mid-2020s. Moon missions may help inform the design for future Mars missions.
