Urey Support Post PCR#2 (Q3 2009 to Q3 2010)

在有效载荷确认审查#2中，重新定义了定于2016年发射的ExoMars巴斯德漫游者仪器套件，ExoMars转变为更具协作性的国际任务。Urey仪器不包括在2016年修订的有效载荷中。在有效载荷确认审查#2中未选择的仪器预计将在2018年和2020年随后的一系列国际合作任务之一中飞行。维持仪器团队的合作，并为2018年和2020年有效载荷的成功纳入做准备，需要举行一系列国际会议、讨论和报告。Urey（图1）是任何太空生物学任务的关键仪器，是2018年的明确竞争者。Urey能够以比以前的原位有机检测系统高许多数量级的灵敏度搜索指示生命和益生元化学的有机化合物。Urey可以使用最先进的分析方法对关键类别的有机分子进行首次搜索，这种方法可以提供万亿分之一的灵敏度。它可以确定这些分子是非生物的还是生物的起源，并可以利用创新的氧化剂传感器评估有机化合物在环境中的生存潜力。这项提案要求为旅费、生活津贴和协作活动提供经费，这些活动将帮助乌里准备在即将到来的任务机会中被选中。支持将加强英国在任何新的科学团队结构中的作用。从2009年第三季度到2010年第三季度，四个星期的差旅费和5%的调查时间包含在Urey的支持费用中。

At Payload Confirmation Review #2, the ExoMars Pasteur Rover instrument suite set for launch in 2016 was redefined and ExoMars was transformed to a more collaborative international mission. The Urey instrument was not included in the revised payload for 2016. Instruments deselected at Payload Confirmation Review #2 are expected to fly in one of a series of subsequent international collaboration missions in 2018 and 2020. Maintaining instrument team collaborations and preparing for successful inclusion in payloads for 2018 and 2020 requires a number of international meetings, discussions and presentations. Urey (Figure 1) is a key instrument for any exobiology mission and is a clear contender for 2018. Urey has an ability to search for organic compounds indicative of life and prebiotic chemistry at a sensitivity many orders of magnitude greater than obtained in previous in situ organic detection systems. Urey can perform the first search for key classes of organic molecules using state-of-the-art analytical methods that provide part-per-trillion sensitivity. It can ascertain whether any of these molecules are abiotic or biotic in origin and can evaluate the survival potential of organic compounds in the environment using innovative oxidant sensors. This proposal requests funding for travel, subsistence and collaborative activities that will help prepare Urey for selection in forthcoming mission opportunities. Support will enhance the UK role in any new science team structure. Four weeks travel and 5% investigator time are included in costings for Urey support from Q3 2009 to Q3 2010.
