イプシロン、打ち上げ延期　機体の追跡条件整わず―ＪＡＸＡ

　宇宙航空研究開発機構（ＪＡＸＡ）は５日、固体燃料ロケット「イプシロン」６号機について、７日午前に予定していた打ち上げを延期すると発表した。打ち上げ後のロケットの位置を追跡するための条件が整わないため。新たな打ち上げ日は未定だが、１１日以降とみられる。（2022/10/05-16:14）

The Japan Aerospace Exploration Agency, or JAXA, said Wednesday that it has postponed the launch of its sixth Epsilon solid-fuel rocket, which was scheduled for Friday morning.
   JAXA made the decision because conditions after the launch are unlikely to be suitable for operations to track the Epsilon-6.
   The Epsilon-6 rocket is expected to be launched Tuesday or later from JAXA's Uchinoura Space Center in Kagoshima Prefecture, southwestern Japan.
   JAXA usually uses radio waves from positioning satellites orbiting Earth to track a rocket after its launch, but it may lose the Epsilon-6 rocket's location in the worst case as satellite positions and other conditions are expected to be unfavorable unless the launch is postponed, according to the agency.
   This is the first time in Japan for a rocket launch to be put off for such a reason, a JAXA official said, adding that it is a "rare case."
