It's important if the spaceship is going to another planet or anything else that could possibly sustain life of any kind (e.g., Jupiter's moon Europa). This is because we want to make sure we're not dumping some of our own life forms on that celestial body.

The same for trips to Mars. If we have an experiment that tries to detect life on anybody we do not what contamination from the earth can give a false positive.
