SpaceX launched its fifth Starship vehicle Oct. 13, successfully making an unprecedented “catch” of its Super Heavy booster back at the launch site.
The Starship/Super Heavy vehicle lifted off from the company’s Starbase site at Boca Chica, Texas, at 8:25 a.m. Eastern on a mission called Flight 5 by SpaceX.
The main upgrade for this test was an attempt by SpaceX to recover the Super Heavy booster by having it come back to the launch site, where it would be cradled by two mechanical arms, sometimes called “chopsticks,” attached to the launch tower it lifted off from. That required the booster to perform precise boostback and landing burns to guide the stage back to the launch pad.
The Super Heavy booster, known as Booster 12, achieved that feat. The booster descended over the pad and the two arms closed around the top of the booster, just below the grid fins, about seven minutes after liftoff, achieving the desired catch of the booster.
Not to mention the landing legs being single use - they have to replace them each landing.
Do they replace the entire legs between flights, or just the crush core?
It was just the crush core iirc but that required servicing the entire leg.
