Stoke Space is developing a fully reusable rocket designed to reuse both its first and second stages. The first stage lands like Falcon 9, while the second stage returns to Earth after delivering its payload using a unique engine with 30 thrust chambers. Its actively cooled heat shield uses...

Let's not get ahead of ourselves. It's still in development. Using CGI and AI to simulate the end product is much easier than actually building and executing. That being said, good luck to them.

Stoke SpaceのNovaロケットの話だね。 投稿の動画は、2段目（上段）を精密にパワードランディングで回収するコンセプトのやつだと思う。 SpaceX（Falcon 9のブースター着陸とかStarshipのベリーフロップ）は「下側」の従来寄りアプローチで、これは「上側」の新しい試みって感じで合ってる。 君の指摘について 「母船（上段）を海に落っこちる従来方式でよくない？」「無重力下の精製物（micro-g製造品）ぐらいしか、こんな丁寧に持ち帰るコストが合わない」 これはめっちゃ鋭い指摘だよ。 実際その通りな部分が大きい。 なぜ「海に落とす」のが主流だったか •上段は軌道速度で再突入するから熱がエグい。回収システム（ヒートシールド + 着陸脚 + 制御系）を積むとペイロードが減る。 •1回使い捨てでも、打ち上げ単価がまだ高かった時代は「新品作った方が安い」ケースが多かった。 •Falcon 9の上段が今も基本的に expend（使い捨てor制御落下）なのも、同じ理由。 でも「丁寧に持ち帰る」価値が出てくるケース Stoke Spaceが狙ってるのはまさにここ： 1Downmass（宇宙→地球への貨物輸送）
これが一番大きい。無重力で作った結晶・タンパク質・半導体材料・医薬品原料とかは、着水の衝撃や海水で壊れやすい。精密パワードランディングなら陸上で優しく受け取れて、回収船も不要。
Stokeはこれを明確に売りにしていて「space cargo logistics」「debris/asset capture and return」と書いてる。 2完全再利用による長期コスト低減
たとえ最初はペイロードが減っても、機体を何十回も飛ばせば元が取れる。Falcon 9の1段目再利用が証明したように。
Stokeは「minimal refurbishment（最小整備）」「24時間以内に再飛行可能」を目指してる。金属製アクティブ冷却ヒートシールド（液体水素で冷やす）がその鍵で、タイルみたいに毎回点検・交換しなくていいのが強み。 3中型市場での差別化
Starshipは「巨大で火星向け・大量輸送」路線。Stoke Novaは中型（LEOで再利用時約3トン）で、GTOや高エネルギー軌道に直接投入しやすく、精密着陸しやすい設計。用途によって住み分けられる。 現実的な壁 •まだ開発中（2026年後半に初飛行予定らしい）。動画もAI生成っぽいって指摘が多い。 •上段再利用はSpaceXも昔検討して一旦諦めた難易度。熱・構造・制御の全部が厳しい。 •ペイロード減少 vs 再利用回数のトレードオフが本当に成立するかは、実際の飛行データが出るまでわからない。 まとめると 君の言う通り、今の標準的な衛星打ち上げだけなら、海に落とす（または制御落下）で十分なケースはまだ多い。
でも宇宙製造・材料科学・将来的な宇宙物流が本格化したら、「丁寧に持ち帰れる」能力が大きな競争優位になる。これはStokeが一番明確に狙ってるポイントだね。 SpaceXのStarshipも上段再利用を目指してるけど、アプローチが全然違う（タイル＋フラップ＋巨大機体）。両方成功したら面白い時代になる。

The only thing Stoke Space have developed at the moment is a good AI generated video at the moment. While SpaceX has already proven the technological expertise which goes all the way from concept, to fast trials, improvement, and production, complete with reusability, and made it a reality. That’s reality versus AI generated video, as far as I can see.

The active cooling concept is elegant. Eliminates ablative refurbishment between flights. But 30 thrust chambers on the second stage… that's a lot of plumbing to manage reliably.

SpaceX once considered recovering the second stage of its rocket, but ultimately decided against it because it wasn't worth the effort.

A Chinese breakthrough shaking up the reusable rocket race! On August 19, 2026, China successfully completed a full mission with the ZhuQue-3 Y2, marking a major step toward the era of reusable rockets. The rocket lifted off from the Dongfeng Commercial Space Innovation Pilot Zone. About 137 seconds later, the two stages separated, with the second stage continuing its flight and successfully placing the Honghu-03 satellite into its designated orbit. But the biggest moment came next: the first stage followed its planned trajectory back to Earth and performed a successful soft landing on land at LandSpace Landing Site No. 1 in Minqin County, Gansu, marking China’s first successful land-based recovery of this type. A rocket that launches, delivers its payload into orbit, then comes back and stands on the ground — this is China building the next generation of reusable launch vehicles.

China has successfully tested a reusable first stage for its Long March-10A rocket using a unique net-based recovery system at sea. Unlike SpaceX, which lands its boosters directly on a drone ship, China recovered the booster with a specially designed offshore platform fitted with a large capture net, marking a different approach to reusable launch technology. Reusable rockets can dramatically reduce launch costs by allowing expensive rocket stages to be flown multiple times. China plans to use the Long March-10 family for future crewed lunar missions, making this technology an important step toward its long-term space ambitions. Could this new recovery method become a serious alternative to SpaceX's reusable rocket system? #China #SpaceX #elonmusk #Falcon9 #ISRO

☄️ The bright object seen over Kyiv may not have been a meteor, but part of Blue Origin’s New Glenn rocket During the recent launch, the first stage performed successfully — it was reused for the first time. However, the second stage encountered an anomaly during its second ignition. As a result, the BlueBird 7 satellite by AST SpaceMobile was placed into a lower-than-planned orbit and is expected to eventually re-enter and burn up in the atmosphere. The re-entry of the second stage is likely what caused the bright fiery trail seen in the sky over Kyiv.
