If we were to ever send a probe to check for life then it's of paramount importance that we do not contaminate the target site with Earth organisms. And if there's anything we've learned from extremophiles is that life is very persistent. How would we go about sterilizing a probe so that we would be sure without a shadow of doubt that no trace of life is clinging to it until it reaches its destination?
