论文摘要
火星样本回报由三个独立的任务组成，其中第一个是2021年2月18日在Jezero火山口降落的Mars2020 Rover。我们在这里描述了我们对Jezero Crater中特定单元的遥感研究，该研究可能是Jezero Crater中的特定单元，该研究很可能是返回样品套件的一部分。我们报告了使用CRISM仪器的数据（包括橄榄石的晶粒尺寸和Fe/mg）数量来表征橄榄石单元的努力。我们还通过类比与西澳大利亚州的含有基质的早龄瓦拉瓦纳集团相比，讨论了该单元的天体学意义。我们还讨论了MSR体系结构的当前状态。
Mars Sample Return consists of three separate missions, the first of which is the Mars2020 rover which will land at Jezero crater on February 18, 2021. We describe here our remote sensing study of a particular unit that outcrops in Jezero crater that is likely to be part of the return sample suite. We report on our efforts to characterize the olivine unit using data from the CRISM instrument, including the grain size and Fe/Mg (Fo) number of the olivine. We also discuss the astrobiological significance of the unit by analogy with the stromatolite-bearing early Archean Warrawoona group in Western Australia. We also discuss the current state of the MSR architecture.
