Mars Spectrometry 2: Gas Chromatography for the Sample Analysis at Mars Data (SAM) Instrument

NASA missions like the Curiosity and Perseverance rovers carry a rich array of instruments suited to collect data and build evidence towards answering if Mars ever had livable environmental conditions. These rovers can collect rock and soil samples and can take measurements that can be used to determine their chemical makeup. <br/><br/> Because communication between rovers and Earth is severely constrained, with limited transfer rates and short daily communication windows, scientists have a limited time to analyze the data and make difficult inferences about the chemistry in order to prioritize the next operations and send those instructions back to the rover. <br/><br/> This project aimed at building a model to automatically analyze gas chromatography mass spectrometry (GCMS) data collected for Mars exploration in order to help the scientists in their analysis of understanding the past habitability of Mars. <br/><br/> More information are available at <a href="https://mars.nasa.gov/msl/spacecraft/instruments/sam/">https://mars.nasa.gov/msl/spacecraft/instruments/sam/</a> and the data from Mars are available and described at <a href="https://pds-geosciences.wustl.edu/missions/msl/sam.htm">https://pds-geosciences.wustl.edu/missions/msl/sam.htm</a>. <br/><br/>We request that you cite the following ackowledgement when using the data provided from this NASA Project: &quot;NASA provided support for the development of SAM. The datasets for these 2 challenges were provided by NASA Goddard Space Flight Center and NASA Johnson Space Center. They have been collected by the Sample Analysis at Mars (SAM) scientists and specifically processed for these challenges with the help of the scientists from NASA: Doug Archer, Charles Malespin, Caroline Freissinet, Stephanie Getty, Luoth Chou, Eric Lyness, and Victoria Da Poian, and the DrivenData team. Data from all SAM experiments are archived in the Planetary Data System (pds.nasa.gov).&quot;

NASA的火星探测任务，如好奇号和毅力号漫游车，携带了一系列精密的仪器，旨在收集数据并构建证据，以解答火星是否曾拥有适宜的居住环境。这些漫游车能够采集岩石和土壤样本，并能够进行测量，从而确定其化学成分。鉴于漫游车与地球之间的通信受到严重限制，传输速率有限，且每日通信窗口短暂，科学家们分析数据并就化学成分做出艰难推断的时间极为有限，以便优先考虑后续操作并将指令发送回漫游车。本项目旨在构建一个模型，自动分析为火星探索收集的气相色谱质谱联用（GCMS）数据，以帮助科学家们分析并理解火星过去的宜居性。更详细的信息可参考<a href="https://mars.nasa.gov/msl/spacecraft/instruments/sam/">https://mars.nasa.gov/msl/spacecraft/instruments/sam/</a>，以及火星数据及其描述可查阅<a href="https://pds-geosciences.wustl.edu/missions/msl/sam.htm">https://pds-geosciences.wustl.edu/missions/msl/sam.htm</a>。在利用本NASA项目提供的数据时，请引用以下致谢语："NASA为SAM（火星样本分析）的开发提供了支持。这两个挑战的数据集由NASA戈达德太空飞行中心和美国宇航局约翰逊航天中心提供。这些数据由火星样本分析（SAM）科学家收集，并由NASA的Douglas Archer、Charles Malespin、Caroline Freissinet、Stephanie Getty、Loth Chou、Eric Lyness和Victoria Da Poian等科学家以及DrivenData团队特别处理。所有SAM实验的数据均存档于行星数据系统（pds.nasa.gov）。"
