Life's capacity to survive in simulated lunar and Martian soils has been explored in two papers published in Scientific Reports. Treating simulated lunar soil with both symbiotic fungi and worm-produced compost can significantly improve the likelihood of reproduction for chickpea plants growing in the soil, indicates one study. A separate paper suggests that some microbes may be able to absorb enough water from the atmosphere to grow in simulated Martian soil at atmospheric humidity levels comparable to those on the planet.
