In Project Hail Mary, the contamination problem arises because Ryland Grace and Rocky's species live in very different biological environments, and their microbes or biological materials could harm each other. Toward the end, Grace is concerned about contaminating Rocky’s homeworld with Earth microbes or vice versa,…
To address this, Grace takes careful precautions to avoid cross-contamination. This includes strict quarantine measures and controlling any biological material transfer between their ships or planets. The goal is to prevent accidental introduction of Earth microbes to Rocky’s world or alien microbes to Earth, which could disrupt ecosystems or cause disease.
Grace’s efforts to solve the contamination problem are part of his broader mission to save Rocky’s star system without endangering either species through unintended biological contamination.
If you want more detail on the specific steps or scientific methods Grace uses to prevent contamination, the book emphasizes his cautious, methodical approach to biosecurity in an alien environment.
