Abstract
The possibility of microbial life beyond Earth presents a fundamental question in astrobiology. Given the likelihood that any extra-terrestrial life will be microbial in nature, the development of sensitive and specific confirmatory tests is crucial for the identification of potential habitats for life. Here, we describe a novel methodology for the detection of microorganisms in Martian soil simulants through spiking and recovery experiments. Our approach employs miniaturised techniques that enable the rapid and sensitive assessment of microbial presence in soil samples. The results of our study suggest that this methodology could be a valuable tool for the identification of potential habitats for microbial life on Mars and other extraterrestrial bodies.
