Cleanroom Robotics: Appropriate Technology for a Sample Receiving Facility?

NASA is currently pursuing a vigorous program that will collect samples from a variety of solar system environments. The Mars Exploration Program is expected to launch spacecraft that are designed to collect samples of martian soil, rocks, and atmosphere and return them to Earth, perhaps as early as 2016. International treaty obligations mandate that NASA conduct such a program in a manner that avoids cross-contamination both Earth and Mars. Because of this requirement, Mars sample curation will require a high degree biosafety, combined with extremely low levels inorganic, organic, and biological contamination.
