The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) Mars flight system is made up of a cruise stage, an aeroshell, and a Phoenix heritage-based lander that successfully landed in the Elysium Planitia on November 26, 2018. InSight has primary science objectives that are aimed at understanding more about the interior of Mars and the formation and evolution of terrestrial planets. As with previous Mars missions, InSight was obligated to satisfy bioburden requirements and verify compliance with international treaty obligations and National Aeronautics and Space Administration requirements before launch. InSight implemented a series of policies and procedures to minimize biological risk and comply with all applicable requirements for a Planetary Protection Category IVa mission. At launch, InSight had an estimated total bacterial spore burden of 1.50 × 10⁵ spores on the entire spacecraft, including the cruise stage, satisfying the requirement of 5 × 10⁵ spores. The landed hardware components required <3 × 10⁵ spores and a bioburden density of <300 spores/m². At launch, the landed hardware of InSight contained an estimated total spore bioburden of 1.35 × 10⁵ spores and an estimated bioburden density of 129 spores/m².

使用地震调查、大地测量学和热传输任务进行内部勘探的行星保护实施。

InSight（使用地震调查、大地测量和热传输的内部探索）火星飞行系统由巡航级、航空壳和基于凤凰遗产的着陆器组成，该着陆器于 2018 年 11 月 26 日成功降落在 Elysium Planitia。InSight 有主要科学目标旨在更多地了解火星内部以及类地行星的形成和演化。与之前的火星任务一样，洞察号有义务满足生物负载要求，并在发射前验证是否符合国际条约义务和美国国家航空航天局的要求。InSight 实施了一系列政策和程序，以最大限度地降低生物风险并遵守行星保护类别 IVa 任务的所有适用要求。在推出时，包括巡航级在内的整个飞船上有^5个孢子，满足5×10 ^{5 个}孢子的要求。着陆硬件组件需要 <3 × 10 ⁵孢子和 <300 个孢子/m ²的生物负载密度。发射时，洞察号的着陆硬件包含估计的总孢子生物负载为 1.35 × 10 ⁵孢子和估计的生物负载密度为 129 个孢子/m ²。
