摘要
OSIRIS-REx将返回碳质小行星Bennu的原始样本。本文描述了如何基于对Bennu的预期以及对受限进度和预算下可实现内容的现实理解来定义“原始”，以及该定义如何转化为要求与实施。为返回原始样本，OSIRIS-REx航天器采样硬件通过精密清洁、材料控制和警惕性保持在等级100 A/2以及采样头上氨基酸和肼<180 ng/cm2。污染通过暴露于航天器装配和测试环境以及太空的见证材料进一步表征。该表征提供了预期背景的知识，并将与存档的航天器组件一起用于与样本进行比较，当样本被送至地球进行分析时。最重要的是，OSIRIS-REx航天器的清洁度是通过科学家、工程师、管理者和技术人员之间的沟通实现的。
