NASA has launched a $3 million global competition to solve a messy but important problem in space travel– how to deal with human waste on the Moon. The goal is to find smart, practical ways to turn waste into something useful that can help astronauts live and work on the Moon for longer periods.
The contest, called the LunaRecycle Challenge , is part of NASA’s bigger plan to support human life beyond Earth without depending too much on supplies from home. As the Artemis program gears up to send people back to the Moon and keep them there longer, being able to recycle waste will be a major step toward sustainable living in space .
Apollo’s leftovers: The forgotten waste on the Moon
According to a TOI report, between 1969 and 1972, six Apollo missions landed astronauts on the Moon. While they brought back valuable scientific samples, they also left behind some unexpected items– like 96 sealed bags of human waste. At the time, leaving them there was the only option because the spacecraft couldn’t carry everything back.
Now, decades later, those waste bags are still sitting on the Moon. But with advances in technology and a growing focus on sustainable space missions, NASA is rethinking whether that waste could actually be turned into something useful.
What NASA is looking for
The LunaRecycle Challenge is calling on researchers, engineers, and innovators from around the world to come up with systems that can turn solid human waste into something useful– like water, nutrients, energy, or soil boosters. Report suggests that these systems need to be small, energy-efficient, and tough enough to work in the harsh conditions on the Moon.
Key objectives of the challenge include:
The LunaRecycle Challenge is centered around four main goals: finding ways to recover useful materials from waste, making sure the process is clean and safe in small living spaces, building systems that need little maintenance and can run on their own, and creating designs that could also work on future Moon or Mars missions, according to the report. The entry period is now over, and the challenge has moved into the review phase. The best ideas will soon be selected to move forward for further development.
A step toward self-sufficient space habitats
For space missions to be sustainable, it’s important to reuse and recycle everything we can. Unlike past short trips, future Moon missions will last longer, have more people, and depend less on Earth. So, waste management isn’t just about staying clean– it’s key to helping astronauts survive. The main idea is to build a system where waste isn’t thrown away but reused—like turning it into clean water, energy, or even something that helps grow food.
Innovations with a dual purpose
NASA’s push for new ideas through the LunaRecycle Challenge isn’t just about space– it could also help people on Earth. The technologies being developed could be useful in places that don’t have good waste systems. Small, energy-efficient recycling systems could be used in remote villages, disaster areas, or off-grid locations, helping improve sanitation while also pushing forward space innovation .
Rethinking waste in the new space age
The LunaRecycle Challenge is part of a bigger change in how we think about living sustainably beyond Earth. It shows that surviving in space isn’t just about building rockets– it’s also about creating smart systems that use every resource wisely, even things we normally see as waste. As NASA plans for a future where people live and work on the Moon, projects like this are helping build stronger, more efficient missions– and they could also lead to real improvements here on Earth.
