Awesome -- dozens of the top people in their fields have been working on the contamination problem and publishing about it for almost two decades.

    The curation team was integrated with mission design and operations from the beginning,
    as early as 2004 (section 3.0). That integration allowed curation-specific needs such as
    contamination knowledge to be incorporated into the mission design early, when adjustments had
    minimal cost impact. Not only did this early integration inform planning for sample
    characterization, cataloging, allocation, and the development of detailed sample handling and
    containment approaches; it was also an investment in the longer term needs of the community.
    Here we describe these preparations for OSIRIS-REx, as a reference for sample scientists and
    curators and as a model for future sample return missions.
