火星卫星探测（MMX）是由日本宇宙航空研究开发机构（JAXA）计划的新的样本返回任务，目标是火星的两个卫星，计划于2024年发射，并于2029年返回地球。此次任务的主要科学目标是确定火卫一和火卫二的起源，阐明早期太阳系的演化过程，通过雪线向具有可居住表面环境的类地行星输送挥发性物质，并探索卫星和火星表面环境的演化过程。为了实现这些目标，MMX将在环绕火星空间停留约3年的时间里，从火卫一收集样本，并对这颗内卫星进行近距离观测，并多次飞越火卫二，对这颗外卫星进行比较观测。同时，利用准赤道航天器沿卫星轨道运行的优势，也将对火星大气进行连续观测。
Martian moons exploration, MMX, is the new sample return mission planned by the Japan Aerospace Exploration Agency (JAXA) targeting the two Martian moons with the scheduled launch in 2024 and return to the Earth in 2029. The major scientific objectives of this mission are to determine the origin of Phobos and Deimos, to elucidate the early Solar System evolution in terms of volatile delivery across the snow line to the terrestrial planets having habitable surface environments, and to explore the evolutionary processes of both moons and Mars surface environment. To achieve these objectives, during a stay in circum-Martian space over about 3 years MMX will collect samples from Phobos along with close-up observations of this inner moon and carry out multiple flybys of Deimos to make comparative observations of this outer moon. Simultaneously, successive observations of the Martian atmosphere will also be made by utilizing the advantage of quasi-equatorial spacecraft orbits along the moons' orbits.
