Earth Sample Return

By serving as another method of retrieving samples on Earth, the Sample Fetch Collector has ensured the best chance of successfully returning a scientifically compelling selection of Earth samples.These first collected and returned samples could answer a key question: did life ever exist on Earth? Only by bringing the samples back can we truly answer the question by using the most sophisticated, state-of-the-art labs, at a time when future generations can study them using techniques yet to be invented.
