NSF and NASA plan to co-sponsor two workshops at the Smithsonian Natural History Museum in August of this year. The purpose is to consider the scientific challenges of unraveling the earliest history of the Earth after its formation, and the relation these processes had in the development of Earth's habitable environment and earliest life up to the appearance of animals. These two workshops are: Workshop 1: The fecundity of the early Earth (Hadean to mid-Archean, ca. 4.6 to 3.0 billion years ago) Workshop 2: Drivers of complexity (earliest oxygenesis through the Cryogenian, ca. 3.0 to 0.6 billion years ago) Workshop participants will focus on defining the next generation of essential questions and opportunities. Interagency collaboration will be promoted between NSF and NASA, a generally underutilized opportunity. Furthermore, and perhaps most importantly, the workshops will bring together scientific subdisciplines which historically have not worked together to provide a more holistic plan for future research directions in early Earth studies. Technical Description: NSF and NASA propose to co-sponsor two complementary, back-to-back workshops at the Smithsonian Natural History Museum during late summer 2014 to define the state-of-the-art in studies of the co-evolution of life and the environment on early Earth - from the beginnings of habitability through the progression of life from the first prokaryotes to complex eukaryotes. These two workshops are: Workshop 1: The fecundity of the early Earth (Hadean to mid-Archean, ca. 4.6 to 3.0 billion years ago) Workshop 2: Drivers of complexity (earliest oxygenesis through the Cryogenian, ca. 3.0 to 0.6 billion years ago) Building from a foundation of the current state of knowledge, workshop participants will define the next generation of essential questions and opportunities. An additional outcome should be a proof-of-concept for underutilized opportunities for interagency collaboration between NSF and NASA. The overarching goal is to build interdisciplinarity at unprecedented levels among diverse fields. The workshops, by design, will bring groups together that are not normally assembled to discuss critical issues and opportunities in early Earth research from diverse but complementary perspectives.

NSF和NASA计划于今年8月在史密森尼自然历史博物馆共同举办两个研讨会。 其目的是考虑解开地球形成后的最早历史的科学挑战，以及这些过程在地球可居住环境和最早生命发展到动物出现的关系。 这两个研讨会是：研讨会1：早期地球的繁殖力（Hadean到中太古代，约。4.6研讨会2：复杂性的驱动因素（最早的氧化作用通过低温期，约30亿年前）。3.0到6亿年前）研讨会的参与者将专注于定义下一代的基本问题和机会。 NSF和NASA之间的机构间合作将得到促进，这是一个普遍未得到充分利用的机会。 此外，也许最重要的是，讲习班将汇集历史上没有一起工作的科学分支学科，为早期地球研究的未来研究方向提供更全面的计划。 技术说明：NSF和NASA计划于2014年夏末在史密森自然历史博物馆共同举办两个互补的背靠背研讨会，以确定早期地球上生命和环境共同进化研究的最新进展-从可居住性的开始到生命的发展，从第一个原核生物到复杂的真核生物。 这两个研讨会是：研讨会1：早期地球的繁殖力（Hadean到中太古代，约。4.6研讨会2：复杂性的驱动因素（最早的氧化作用通过低温期，约30亿年前）。3.0在当前知识状态的基础上，研讨会参与者将定义下一代的基本问题和机会。另一个成果应该是NSF和NASA之间未充分利用的机构间合作机会的概念验证。总体目标是在不同领域建立前所未有的跨学科性。讲习班的设计将使通常不会聚集在一起的团体聚集在一起，从不同但互补的角度讨论早期地球研究中的关键问题和机会。
