论文摘要
火星麦克风是SuperCAM的五种测量技术之一,SuperCAM是Chemcam仪器的改进版本,它已经在好奇心流动站上运行了几年。 SuperCam位于流动站的桅杆单元,以利用漫游车头的独特指向功能。除了是第一个在火星上录制声音的乐器外,超级型麦克风还可以解决几个原始的科学目标:与激光对火星岩石的影响相关的声音研究,以更好地了解它们的机械性能,改善我们对火星表面的大气现象的知识:大气湍流,对话性涡流,尘埃互动,与Rover的粉尘相互作用。麦克风还将帮助我们理解流动站不同动作的合理签名:机器人手臂和桅杆的操作,在火星的粗糙地面上行驶,对泵的监视等...超级摄像头麦克风在2019年初交付给超级车务员团队,并在2019年初交付了超级弹药实验室(Jpl,Pasadena,Pasadena,ca,ca,CACAM)。火星2020年的任务于2020年7月启动,并于2021年2月18日降落在火星上。预计任务运营将持续到至少至2023年8月。麦克风运行完美。
The Mars Microphone is one of the five measurement techniques of SuperCam, an improved version of the ChemCam instrument that has been functioning aboard the Curiosity rover for several years. SuperCam is located on the Rover's Mast Unit, to take advantage of the unique pointing capabilities of the rover's head. In addition to being the first instrument to record sounds on Mars, the SuperCam Microphone can address several original scientific objectives: the study of sound associated with laser impacts on Martian rocks to better understand their mechanical properties, the improvement of our knowledge of atmospheric phenomena at the surface of Mars: atmospheric turbulence, convective vortices, dust lifting processes and wind interactions with the rover itself. The microphone will also help our understanding of the sound signature of the different movements of the rover: operations of the robotic arm and the mast, driving on the rough floor of Mars, monitoring of the pumps, etc ... The SuperCam Microphone was delivered to the SuperCam team in early 2019 and integrated at the Jet Propulsion Laboratory (JPL, Pasadena, CA) with the complete SuperCam instrument. The Mars 2020 Mission launched in July 2020 and landed on Mars on February 18th 2021. The mission operations are expected to last until at least August 2023. The microphone is operating perfectly.
