１１月５日，日本在用自制的ＨＺ火箭发射一颗多功能卫星时，在火箭升空３分５９秒后，第一节火箭的主机比预定时间提前２分钟停止运转，当第一节火箭分离后，机体位置、速度等一切数据突然消失，卫星无法进人预定轨道，地面控＄忡心不得不下达指令将第二Ｉ节主机引爆。在日本? On November 5th, when Japan launched a multi-purpose satellite with its own HZ rocket, after the rocket was airborne for 3 minutes and 59 seconds, the host of the rocket in the first quarter stopped operating 2 minutes earlier than scheduled time, when the first rocket was launched.

The satellites could not enter the scheduled orbit, and the ground control had to issue instructions to detonate the second section I host. In Japan?
