Studying the human-borne microorganisms is significant for human welfare and future crewed missions in space, whilst the extremophiles are vital for studying the physiological requirements of survival in space. [2] NASA has pointed out that normal adults have ten times as many microbial cells as human cells in their bodies. [3]
Viruses were expected to be small, but the range of sizes came as a surprise.
