It appears to be an earth-shattering kaboom.

Not sure why there’s no audio, but I assume it was loud. Presumably no one was hurt; Mary was reportedly quite a ways away when she took this. Starhopper looks OK, but we’ll hear more soon. I was watching the live stream; it seems to be still burning. One of the benefits of stainless is that it’s cheap, compared to carbon composite.

Worth noting, as Eric does, that the static test was successful, FWIW. So this is the biggest advance they’ve made yet on the SN series. Next challenge is to do a static test without an explosion afterward.

[Saturday-morning update]

Here’s one with audio. Note the delay due to the distance. Has to be over half a mile away.

An article about the safety of the system, with a quote from Leroy Chiao: “Chiao said pushing too hard for safer numbers could cause a spaceflight program to spiral into never launching at all.”

You don’t say.
