If SAM does spy a potential organic, it will aim to determine if it's actually from Mars, or hitchhiking strays from Earth contaminating the samplecollector.
Braun, the 2011 National League MVP, told reporters that nearly two days passed between when a collector took his sample and when it was delivered to a FedEx office.
The collector did not send the sample to the laboratory until Monday, thinking it would be more secure at home than at a Federal Express office during the weekend.
