新华社东京12月17日电（记者钱铮）日本宇宙航空研究开发机构（JAXA）17日下午说，冷却水注水设 备异常导致当天上午H3火箭发射被紧急叫停。 JAXA原定17日11时11分（北京时间10时11分）用一枚H3火箭发射准天顶卫星系统的"引路5号"卫星。 该机构当天下午在南部鹿儿岛县种子岛宇宙中心召开新闻发布会说，火箭即将点火时，冷却水注水设备 发生异常，发射任务紧急停止。火箭和卫星没有受损，已在调查故障原因。 该机构H3项目团队负责人有田诚介绍说，冷却水注水设备由导流壁冷却水系统和烟道部注水系统组 成，该设备用于冷却火箭发射时喷出的高温尾焰喷流，以保护导流壁和烟道。当天火箭即将点火时，设 置在储水罐下游的压力传感器检测到冷却水流量不足。 此次发射任务最初定于12月7日进行，由于运载火箭第二级箭体搭载的惯性测量单元出现异常而被推 迟。（完） ...
