（东京18日综合电）流星雨本是自然现象，惟未来或可随时人工控制制造出来。日本宇宙航空研究开发机构（JAXA）周五（18日）上午，于鹿儿岛县内之浦太空中心发射小型火箭“艾普斯龙4号”。火箭共搭载7个卫星，包括能从上空释放特殊金属粒人工制造流星的的卫星。

要制造人工流星，围绕地球飞行的卫星释放出5至20个特殊金属粒，这些金属粒在6至8万米上空燃烧后，会像流星那样发光，可用于节庆活动。由于该个卫星载有400粒球体，相信足够在20至30次活动中发放。

今次是艾普斯龙首次实现一箭多星，其他卫星还包括由东北大学研发的观测卫星，可从上空利用感测器监控农田，掌握农作物生长状况。艾普斯龙是通过现有技术降低成本的火箭，发射费用约为55亿日圆（近2亿令吉）。
