日本の民間宇宙企業スペースワンは、日曜日にKairos小型ロケットの第3回打ち上げを天候不良により中止した。これにより、同社が国産ロケットで衛星を軌道に乗せる初の日本民間企業となる試みがさらに遅れることになった。先週水曜日の試みも同様に天候で延期されていた。
スペースワンは、18メートルのKairosロケットの打ち上げを、日曜日に天候不良のため中止したと発表した。これが過去1週間での2回目のキャンセルで、先週水曜日の試みも悪天候で延期されていた。
同社は、国産ロケットで衛星を軌道に乗せる初の日本民間企業を目指しているが、2024年に2回の失敗を経験している。最初のKairosロケットは3月に離陸直後に爆発し、2回目は12月に打ち上げから約3分後に中止された。
今回のキャンセルにより、スペースワンの野心的な目標達成がさらに遠のいた。会社は天候の改善を待って新たな日程を検討する方針だ。

NASA has overhauled its Artemis program, postponing the first human moon landing until the Artemis IV mission in early 2028. The changes, announced by Administrator Jared Isaacman on February 27, 2026, aim to increase launch frequency and reduce risks after repeated delays with the Space Launch System rocket. An additional test flight, now Artemis III, will focus on low-Earth orbit rendezvous with commercial lunar landers.
NASA has canceled the Exploration Upper Stage for its Space Launch System rocket as part of a major revision to the Artemis program. The decision, announced by Administrator Jared Isaacman, aims to accelerate lunar landings by focusing on surface activities and using more efficient upper stages. This move supports testing of human landers from SpaceX and Blue Origin ahead of missions in 2027 and 2028.
