Story summary
- Researchers led by Harrison Coker of Texas A&M University found that mixing human waste with regolith could enable astronauts to grow crops on Mars and the Moon.
- Experiments show that mixing sewage with simulated regolith released nutrients such as sulfur, calcium, and magnesium.
- However, challenges remain because real Martian and lunar regolith may behave differently.
- Earlier studies show fertilized lunar regolith supports crop growth better than Martian regolith.
