本文描述了JPL的高保真使命概念系统试验台，该试验台用于支持InSight（使用地震调查、大地测量和热传输的内部勘探）使命概念研究。洞察号使命将使用三种仪器对火星内部进行地球物理探测。SEIS地震计监测地震活动和潮汐位移; 2. RISE X波段无线电多普勒跟踪实验测量旋转变化;和3。HP 3：热流和物理性质探头确定地热热流。法国空研中心提供了SEIS，德国航天中心提供了HP 3。这些仪器的测量将产生有关行星初始吸积过程的信息，其核心，地壳和地幔的形成和分化，以及随后的内部演化。SEIS和HP 3仪器将使用与凤凰号火星着陆器使命上使用的机械臂类似的机械臂和从凤凰号和MER继承的操作经验部署到火星表面。SEIS和HP 3将在一个火星年内每三小时进行一次监测，不需要地面在环互动。洞察号是美国宇航局发现计划于2011年5月选定的三项拟议任务之一，用于资助进行初步设计研究和分析。洞察号于2012年8月被选为美国宇航局发现计划的第12个使命。
This paper describes a high fidelity mission concept systems testbed at JPL that was used to support the InSight (Interior Exploration Using Seismic Investigations, Geodesy, and Heat Transport) mission concept study. The InSight mission would conduct geophysical exploration of Mars' interior using three instruments 1. SEIS seismometer monitors seismic activity and tidal displacements; 2. RISE X-band radio Doppler tracking experiment measures rotational variations; and 3. HP3: Heat-flow and Physical Properties Probe determines the geothermal heat flux. CNES contributes SEIS and DLR contributes HP3. The measurements from these instruments would yield information about processes that occurred during the initial accretion of the planet, the formation and differentiation of its core, crust, and mantle, and subsequent evolution of its interior. The SEIS and HP3 instruments will be deployed to the surface of Mars using a robotic arm similar to the robotic arm used on the Mars Phoenix Lander mission and operational experience inherited from Phoenix and MER. The SEIS and HP3 will be monitored every three hours for one Mars year, with no ground-in-the-loop interaction required. InSight was one of three proposed missions selected by NASA Discovery Program in May 2011 for funding to conduct preliminary design studies and analyses. InSight was selected in August 2012 as the 12th mission in the NASA Discovery Program.
