@TheresaLubowitz I was supposed to leave Rise in Integrity….but that was not something I was going to do. I stuffed that little guy in a dry bag we had in our survival kit and hooked the bag onto my pressure suit.

On the helicopter leaving the ship right now. This planet is impossibly beautiful from every altitude I’ve seen it…surface to 250,000 miles

Is this about how long it took for Apollo to get from splashdown to opening the hatch?

And splashdown! America is back in the business of sending astronauts to the Moon and bringing them home safely. Reid, Victor, Christina, and Jeremy did an outstanding job. These talented astronauts inspired the world and represented their space agencies and nations as humanity’s ambassadors to the stars. This was a test mission, the first crewed flight of SLS and Orion, pushing farther into the unforgiving environment of space than ever before, and it carried real risk. They accepted that risk for all we stood to learn and for the exciting missions that follow, as we return to the lunar surface, build a Moon base, and prepare for what comes next. And they were not alone. The entire NASA workforce, our commercial and international partners, and the hopes and dreams of people all over the world were with them. The astronauts know it, and you should too. This mission would not have been possible without you. Congratulations. Artemis II, mission accomplished.

A better view. I might be mixing up two different things with my pictures. This one is definitely the Full Fuselage Trainer

In 2011, I got to get into the shuttle Full Fuselage Trainer at Johnson Space Center in Houston. Seeing the Artemis live camera view now reminds me a little of that

A lot of people don't realize that reentry is the scariest part. Not the distance to the moon. Not the engine burns. Reentry. The intense heat and pressure. I'm not sure I'm even going to watch

拡散ではなくて共感して下さい。 今夜(日本時間4月11日未明)、NASAのアルテミスIIが地球に帰ってきます。 速度は約4万km/h。外壁温度は約2,800℃。 4名の命を守る盾は、直径5mのヒートシールド1枚だけです。 ここで多くの方が知らない事実があります。 2022年の無人テストアルテミスIで、このヒートシールドは100箇所以上にひび割れました。 素材(Avcoat)の内部にガスが閉じ込められ、圧力で亀裂が走ったのです。 NASAはその後4年間、徹底的に原因を調べました。 そして出した答えが「シールドは交換しない」でした。 素材はアルテミスIと同じ。製造プロセスも基本的に同じ。 変えたのは帰還ルートだけです。 前回使ったスキップ再突入(石を水面で弾ませるような軌道)を廃止し、より急角度の直接突入に切り替えました。 加熱時間は最大14分から約8分に短縮。 その代わり、乗組員にかかる減速Gは大きくなります。 この判断を承認したNASAのIsaacman長官は、2026年1月、自らこう認めています。 「長期的にはこれが正しいやり方ではない。プランBも存在しない。」 再突入はやり直しが効きません。 軌道に入ったその瞬間から、シールドが保つか保たないかの一回勝負です。 今回が成功しても、根本的な設計課題はアルテミスIIIに持ち越されます。 NASAはすでにアルテミスIII用に改修版シールドの導入を決めています。 つまり今夜帰還する4名は「改修前の設計」で大気圏に突っ込む宇宙飛行士です。 人類の月面帰還という夢のために、技術的リスクとスケジュールの間で折り合いをつけた判断。 この選択が正解だったかどうか、今夜の海面が答えを出します。
