Urey有机和氧化剂探测器由一套仪器组成，旨在搜索火星风化层中的几类有机分子，并利用手性测量确定这些化合物是由生物还是非生物过程产生的。这些实验还将根据表面和大气氧化剂的存在和化学反应性，确定宿主风化层内有机分子的化学稳定性。尤里已被选定为欧洲航天局（欧空局）即将到来的2013年ExoMars探测器使命的巴斯德有效载荷。Urey的各种有效能力使其成为有效载荷的一个组成部分，并将有助于实现使命的主要科学目标的很大一部分：“寻找火星上过去和现在的生命迹象。“这台仪器是以哈罗德·尤里的荣誉命名的，因为他在宇宙化学和生命起源领域做出了开创性的贡献。
The Urey organic and oxidant detector consists of a suite of instruments designed to search for several classes of organic molecules in the martian regolith and ascertain whether these compounds were produced by biotic or abiotic processes using chirality measurements. These experiments will also determine the chemical stability of organic molecules within the host regolith based on the presence and chemical reactivity of surface and atmospheric oxidants. Urey has been selected for the Pasteur payload on the European Space Agency's (ESA's) upcoming 2013 ExoMars rover mission. The diverse and effective capabilities of Urey make it an integral part of the payload and will help to achieve a large portion of the mission's primary scientific objective: "to search for signs of past and present life on Mars." This instrument is named in honor of Harold Urey for his seminal contributions to the fields of cosmochemistry and the origin of life.
