星舰第十二次飞行测试（从起飞到溅落）

Added: 2026-05-24

[00:00:00]- 10 9 8 7 6 5 4 3 ignition.

[00:00:15]We have set you down range.

[00:00:36]Mr. Raptor, chamber pressure nominal.

[00:00:44]All right, we are T plus 30 seconds into flight. T 33 out of 33 Raptor 3 engines on booster V3 ascending over the Gulf now. Coming up on maximum aerodynamic pressure.

[00:00:58]>> Booster and ship. Avionics power.

[00:01:04]Telemetry nominal.

[00:01:07]>> Systems looking good. We're just passing through the period of maximum dynamic pressure.

[00:01:17]A little over a minute into flight now.

[00:01:21]Vibrations chilling out here at Star Factory as we continue to watch Starship flight 12 arc out over the Gulf. The next major thing coming up is going to be hot staging.

[00:01:34]>> Booster process stop.

[00:01:35]>> Reminder, we do what's our version of MOO. Most engines cut off. So, we're going to shut down all but five of the Raptor engines on the booster.

[00:01:46]And then after that happens, we're going to ignite the six engines on ship while it is still attached.

[00:01:54]We have clamps that hold the two together. Those are going to retract inside of that hot stage ring, kind of protect them.

[00:02:03]Look like we had one of the engines go out. Still flying on 32 of the Raptor engines. But again, once we get the hot staging, those six engines on the ship are going to ignite.

[00:02:16]We're going to do it in a little bit different of a of a of a sequence on version three. Essentially, those three ARVAC engines will ignite first. Almost immediately after, just one of those central engines is going to ignite. And that's going to give the booster a bit of a kick, sending it in a known direction, followed shortly after by the other two.

[00:02:43]>> We're through Mo. separation.

[00:02:54]There you go. Successful hot staging separation.

[00:03:00]We are not seeing as many booster engines ignite as we expected for boost back, but we are seeing six good engines lit on ship.

[00:03:09]It looks like we just had an early boost back shutdown. Again, a reminder, the booster was planned to essentially head into the Gulf uh for a splashdown, but it has shut its engines down early on into boost.

[00:03:27]And we just see one of the Arvac. So, we're now running on five engines on ship.

[00:03:37]We do have engine out capability. So, it's going to continue into its ascent.

[00:03:45]You got booster on the left there, ship on the right.

[00:03:50]>> Chip avionics power.

[00:03:52]>> Not planning on bringing the booster back for this flight as this was the very first time.

[00:04:06]All right, so we're about 3 minutes 50 seconds into today's flight. Uh just a reminder, the the ship planned to burn its engines uh for about 8 minutes and change. Uh about 8 minutes and 11 seconds was our planned timeline for today. Uh that could shift slightly as we do have one engine out running on one fewer Arvac again continuing to watch. So booster did not complete its boost back burn. We would not see all of the engines ignite that we expected.

[00:04:45]Are continuing to get some views from it though. That's going to make a splash down somewhere in the in the Gulf.

[00:04:52]Reminder, we clear air, sea space, everything uh for these launches.

[00:05:09]All right. So, we are coming up on T + 5 minutes.

[00:05:16]Ship continuing to fire. Five of the six.

[00:05:24]Standing by for callouts. Making sure ship's on its planned trajectory. Again, we are planning a suborbital trajectory for the ship today.

[00:05:36]booster giving us some views as it continues to make its way back down towards the water.

[00:05:46]All right, so a little over five and a half minutes in flight. Kate, Jake, you guys with me? Looks like boosters starting to come in hot.

[00:05:54]>> Yeah, we had a the opportunity to stand outside to watch and wow that was incredible. Yeah, that was really loud, really shaky, and I was actually surprised how fast the booster got off the pad or the whole stack. That was that was quite incredible.

[00:06:09]>> Absolutely. So, we have views here from the booster coming back down, making its way into the Gulf.

[00:06:17]Pretty cool to see.

[00:06:18]>> We have healthy chamber pressures on five out of six ship engines.

[00:06:21]>> Great news there for Starship.

[00:06:30]Once again, we were not going to bring the super heavy booster back to the tower. We were planning on having it land in the Gulf.

[00:06:46]And it looks like the booster ended its mission there in the Gulf. But we've got a ship still flying. Great to see that.

[00:06:54]Still have five out of six engines there on S39.

[00:06:57]>> Yes, we also heard good chamber pressures as well on those engines that are lit. We do have engine out capability. We do see that we have one of the arvac, one of the Raptor vacuum engines that is currently out, but that's okay. Ship is continuing on.

[00:07:13]Amazing views of planet Earth there in the background.

[00:07:19]>> Yeah, I love the S39 decal there. That just gives the gives the ship a little bit of character. And again, all these great views brought to you by Starlink, of course.

[00:07:36]>> Yeah. Obligatory shout out to the entire Starship avionics, camera, electronics team. Did a whole lot of work to to get these upgraded cameras.

[00:07:47]A look inside of the ship skirt. You can see those three center engines ignited.

[00:07:51]The Arvac's continuing to fire as well.

[00:07:54]We did we did see at least a couple engines fire up on booster for that landing burn before we lost contact with it.

[00:08:02]We should have just a little over 20 seconds to go. We'll see if the burn extends a little bit.

[00:08:16]We have 20 of these Starlink simulator satellites and then we have two of these specially modified um as we call them dodger dogs here around here. Uh those as Dan mentioned earlier they have some V3 tech on them some solar arrays and >> that's right charged uh PEZ dispenser really good and especially once we you know fill Starship up all the way with around 60 or so of these Starlinks being able to deploy them fairly expediently uh you know is going to be important for designing the overall mission profile.

[00:08:54]>> Yeah.

[00:08:56]Now, fans of Starship may know that Starlink enables lots of unprecedented views both from space as we see here and on Earth. In addition to the dozens of cameras on Starship itself, we also have mobile Starlink camera kits deployed in the Indian Ocean.

[00:09:14]>> Yes, Starlink also connect at other strategic camera spots around Texas.

[00:09:20]It's all part of how it all comes together to tell the incredible story of Starship both on and off planet.

[00:09:29]>> Yep.

[00:09:33]>> All right. Simulators to go out satellites engines. So in space relight and then coming up are our Dodger dogs.

[00:09:48]So these are mod going to get scaring and these our chance >> to the Indian Ocean in less than an hour. Yeah, she flies pretty fast.

[00:10:19]>> She flies very fast.

[00:10:29]>> Peak next 10 minutes where we're going is a flip of the structure. We're going to try and do that today. Uh since we did skip the inspace burn, we're carrying a little bit of extra propellant in our header tanks up in the nose. And so that's going to put a little bit of extra stress on those forward flaps as we come in. So we will see if they're able to hold through through that re-entry. Um so that will be another watch item. We did skip that in space burn. Uh but we are expecting at least two of those sea level engines to try and ignite for a landing burn. Um we entered the entry period in a good attitude. Um, so hopefully making our way to the targeted splashdown point.

[00:11:14]We've got that Starship recovery team standing by and we should be about 10 minutes away from splashdown.

[00:11:23]>> Back to the pad. This is the same reason why we were um, you know, intentionally not trying to bring the booster back to the pad. So, we're trying all these things out in this developmental phase of the vehicle uh, and you know, really proving what a test flight is.

[00:11:40]Absolutely.

[00:11:40]>> Dynamic pressure is coming down.

[00:11:43]>> All right, we heard there dynamic pressure coming down and I'd say we're in a pretty good bank right now.

[00:11:50]>> Yeah, executing the power slide. We're about 90 seconds away from our anticipated landing burn. Clouds coming up. Pretty sunrise on the other side of the planet.

[00:12:04]>> Starship is subsonic and is on target.

[00:12:12]The crowd here reacting to that call out, letting us know that we are on target for this precise landing in the Indian Ocean. This will once again be a soft splashdown.

[00:12:25]We should get some pretty cool views from the recovery team who we chatted with earlier. They are standing by to receive this ship. Once again, this is the first flight of our completely redesigned Starship version three.

[00:12:39]Yeah. And if you remember the suborbital flights from a few years ago, this is very much the same regime that we're in here. So, we're sub 15 km executing what we call the belly flip maneuver.

[00:12:52]>> Ah, yes. Serial number eight, the first belly flop. I remember it well.

[00:13:06]Just some really amazing views of the Earth as the ship is coming back home.

[00:13:14]Thanks, Starlink.

[00:13:24]>> Yeah, you can see the aft flap there making minor corrections.

[00:13:28]>> Starship is turning for final approach to landing site. Look at that turn.

[00:13:32]>> There we go. Minor corrections and a full turn.

[00:13:38]>> Yeah, Starship doesn't fly like an airplane. It's a lot more like a sky diver.

[00:13:43]Full belly flop on the way down. Using those flaps similar to arms to help change the the the path of the air over you. Coming up real soon. Again, going for a landing burn. Trying to light two of these Raptor sea level engines.

[00:14:03]Landing burn startup.

[00:14:05]>> Landing burn start up.

[00:14:09]>> Two engine flip.

[00:14:16]Successful flip.

[00:14:26]Good shot time.

[00:14:31]Oh, amazing.

[00:14:52]That wall of fire
