Even nearly empty, the booster is heavy enough and the BE-4 can throttle low enough that it doesn't need to do a suicide burn. Instead, and as they just demonstrated, it can just gently lower itself down on the deck. Takes more prop to do so, but for a second attempt, the decision to play it safe was perfectly sound. It's practically guaranteed that they'll dial the margins in with more flights. This might be the softest landing that a New Glenn ever experiences. permalink fedilink source parent hideshow 4 child comments replies: [–] burble@lemmy.dbzer0.com 3 points 11 months ago (3 children) I wonder if they'll go with for full Falcon 9 style suicide burn at some point. permalink fedilink source parent hideshow 3 child comments replies: [–] bear@lemmy.blahaj.zone 3 points 11 months ago (1 child) I assume that's a method of using the minimum amount of thrust and time in the air? So, full blast at the last possible second? permalink fedilink source parent hideshow 1 child comment replies: [–] burble@lemmy.dbzer0.com 2 points 11 months ago* Yup. Falcon 9's Merlin engines have too high of a thrust to weight ratio to hover, so they have to do a last second burn. If it doesn't work, boom. It does also save fuel. permalink fedilink source parent [–] Bimfred@lemmy.world 1 point 11 months ago If they do, it won't be anytime soon.
