US scientists grow chickpeas in lunar soil simulant for first time

Scientists from The University of Texas at Austin and Texas A&M University have successfully grown and harvested chickpeas using lunar soil simulant, marking the first time a crop has been cultivated in “moon dirt.” This research supports NASA’s Artemis mission by exploring sustainable food production on the Moon. Lunar regolith, the Moon’s surface dust, is chemically and physically hostile to plant growth due to its lack of organic matter and presence of toxic heavy metals. To overcome this, researchers mixed the simulant with nutrient-rich vermicompost derived from earthworm-processed mission waste and inoculated the chickpeas with arbuscular mycorrhizae fungi. This symbiotic fungus helped the plants absorb nutrients while filtering out harmful metals, enabling chickpeas to thrive in soil mixtures containing up to 75% lunar simulant. While the successful harvest is a significant milestone, further research is needed to determine the safety and nutritional value of these chickpeas for astronaut consumption. The next phase of the NASA-funded project will analyze whether
