This proposal focuses on investigations of the surface of solar system bodies. It has three major objectives: 1. Develop methods to measure the topography of Bennu - the target asteroid of the NASA OSIRIS-REx mission that includes a Canadian laser altimeter.. 2. Understand the effects of the unique environments associated with planetary missions on the measurements from in-situ instruments 3. Prepare for the analysis of Canada's first sample returned from space These objectives capitalize on two large Canadian investments in planetary exploration. The first of these is a $61 Million investment in Canada's participation in the NASA New Frontiers Mission OSIRIS-REx to a primitive carbonaceous near-Earth asteroid (www.asteroidmission.org). The second is a $3.35 Million dollar project funded primarily by the Canadian Foundation for Innovation and the Ontario Research Fund. This project The CAnadian Planetary Simulator (CAPS) was successful in 2015 and will be located at York University. The students trained on these projects will acquire a broad range of analytical skills applicable to many Canadian industries. Asteroid Topography The Canadian laser rangefinder on the OSIRIS-REx mission to a near-Earth asteroid has a capable two-dimensional scanning system - the first of its kind for any planetary mission. This capability and its high precision require new methods of data analysis and asteroid topographic assessment. This Canadian contribution to the NASA mission has the potential to revolutionize the study of asteroids and comets. We will provide these techniques and capitalize on the investment in Canadian technology. Environmental Effects A major goal of this research is to provide measurements of relevant planetary surface analogues using a variety of techniques. The CAPS' ability to provide correlated measurements of planetary surface materials with a broad set of techniques opens up a research area that has not been well exploited. The goal of these investigations is to improve the quantification of the results of standoff measurements using improved techniques and/or a combination of techniques. This will improve the interpretation of science data from missions to objects in our solar system. OSIRIS-Rex Sample Analysis An important component of the OSIRIS-REx mission that is currently needed is a facility that will protect the sample from Earth-based contamination (particulate, organic and atmospheric) while allowing a set of Canadian investigations to be conducted. CAPS will fill this need for the Canadian community (and some of the international community as well) for this clean experimental environment. This project will develop the handling protocols that will allow the investigation of this important sample. These protocols and techniques will be critical to the set of planned investigations and those that are still in development until the 2023 return and beyond.

该提案的重点是对太阳系天体表面的研究。它有三个主要目标： 1. 开发测量 Bennu 地形的方法，Bennu 是 NASA OSIRIS-REx 任务的目标小行星，其中包括加拿大激光高度计。 2. 了解与行星任务相关的独特环境对现场仪器测量的影响 3. 准备分析加拿大第一个从太空返回的样本 这些目标利用了加拿大在行星探索方面的两项大型投资。第一个是加拿大投资 6100 万美元参与 NASA 新前沿任务 OSIRIS-REx，前往原始碳质近地小行星 (www.asteroidmission.org)。第二个是一个 335 万美元的项目，主要由加拿大创新基金会和安大略研究基金资助。该项目加拿大行星模拟器 (CAPS) 于 2015 年取得成功，并将设在约克大学。接受这些项目培训的学生将获得适用于加拿大许多行业的广泛分析技能。 小行星地形 OSIRIS-REx 近地小行星任务中的加拿大激光测距仪拥有强大的二维扫描系统，这是所有行星任务中的第一个此类系统。 这种能力及其高精度需要新的数据分析和小行星地形评估方法。 加拿大对美国宇航局任务的贡献有可能彻底改变小行星和彗星的研究。我们将提供这些技术并利用对加拿大技术的投资。 环境影响 这项研究的一个主要目标是使用各种技术提供相关行星表面类似物的测量。 CAPS 能够利用广泛的技术提供行星表面材料的相关测量，开辟了一个尚未得到充分开发的研究领域。这些研究的目标是使用改进的技术和/或技术组合来改进对距离测量结果的量化。这将改善对太阳系物体任务中科学数据的解释。 OSIRIS-Rex 样品分析 目前 OSIRIS-REx 任务的一个重要组成部分是一个设施，该设施将保护样本免受地球污染（颗粒物、有机物和大气），同时允许加拿大进行一系列调查。 CAPS 将满足加拿大社区（以及一些国际社会）对这种清洁实验环境的需求。该项目将制定处理协议，以便对这一重要样本进行调查。这些协议和技术对于计划中的调查以及 2023 年回归及之后仍在开发中的调查至关重要。
