The Italian engineer of NASA: “I will protect the Earth from the risk of contamination by the biological material that we will bring from Mars”

As head of Backward planetary protection, in the Mars Sample Return program, he must ensure that when the US space agency brings the samples taken from Mars back to our planet, we will not risk contamination with possible harmful microorganisms.
