Mars fungi could make red planet regolith fertile for crops

Phys · · 626 words · By Laurence Tognetti

The article discusses a review paper published in Frontiers in Astronomy and Space Sciences regarding the potential use of beneficial fungi, such as arbuscular mycorrhizal fungi, to make lunar and Martian regolith fertile for crop production. It explains the concept of in situ resource utilization (ISRU) to reduce the logistical burdens of transporting supplies from Earth.
