运载火箭从种子岛吉信发射场的 2 号发射台点火起飞。 由日本宇宙航空研究开发机构（JAXA）主导的 MMX 任务将进入火星轨道，对火星的两颗卫星火卫一和火卫二开展研究。如果一切按计划推进，MMX 将成为首枚登陆火卫一并把样本带回地球研究的探测器。科学家认为，这些样本有望解开持续数十年的卫星起源之谜，同时揭示早期太阳系形成的相关线索。 这是日本这款两级一次性 H3 火箭的第十次发射，该火箭由日本宇宙航空研究开发机构与三菱重工业联合研发。火箭离开发射台后，这枚高 207 英尺（63 米）的运载火箭沿预定轨道在太平洋上空爬升，飞行接近两分钟时，四台固体助推器成对分离。约一分二十秒后，火箭抛掉整流罩，MMX 探测器首次暴露在太空真空环境中。 据三菱重工业介绍，H3 火箭一级由两台
