日本宇宙航空研究开发机构（JAXA）近日成功完成了其实验性可重复使用火箭 RV-X 的首次试飞，该火箭在升空后实现了安全着陆 [1]。此次测试的主要目标是掌握降低发射成本的关键技术，以应对由 SpaceX 主导的全球太空市场并提升国家竞争力 [1]。
项目主管 Takashi Ito 确认火箭已按计划飞行并成功落地 [1]。本次试飞中，RV-X 火箭的飞行高度达到了 11 米（36 英尺），水平移动距离为 16 米（52 英尺）[1]。在技术验证方面，该项目的发动机此前已完成过 165 次燃烧测试 [1]。
根据规划，未来 JAXA 计划将 RV-X 火箭的试飞高度提升至约 100 米（218 英尺）[1]。
Japan's space agency JAXA has successfully conducted the maiden test flight of its experimental reusable rocket, designated as RV-X [1]. The mission achieved a safe landing after launch, marking a significant step in mastering key technologies to reduce launch costs and enhance national competitiveness against global leaders like SpaceX [1]. Project supervisor Takashi Ito confirmed that the vehicle flew according to plan and landed safely upon completion of the test [1]. During this initial trial, the rocket reached an altitude of 11 meters (36 feet) before moving horizontally for a distance of 16 meters (52 feet) [1]. The propulsion system utilized during the flight had previously undergone 165 combustion tests to ensure reliability [1]. Looking ahead, JAXA plans to increase the test flight height to approximately 100 meters (218 feet) in future missions [1].
