Researchers grow chickpeas in simulated lunar soil

Researchers at the University of Texas at Austin have successfully cultivated and harvested chickpeas using simulated lunar regolith. This research, published in the journal Scientific Reports, aims to address food production challenges for future missions like Artemis II. Simulated lunar soil presents significant obstacles to plant growth due to high concentrations of metals like aluminum and zinc, poor water drainage, and a lack of essential soil microbiomes. To overcome these limitations, the team, led by postdoctoral fellow Sara Santos, used vermicompost as a natural organic fertilizer. Additionally, half of the plant samples were inoculated with fungi to establish a symbiotic relationship. These fungi help plants absorb necessary nutrients while simultaneously reducing the uptake of heavy metals. This study serves as a critical step in understanding potential agricultural self-sufficiency on the lunar surface.
