alphatool, in Derek Newsome @DerekdotSpace: "Saw some concern earlier about SLC-6s flame trench holding up to Falcon Heavy due to Delta IV Heavy having significantly less thrust, I'd like to put that to rest."

The article is worth it just for the pictures! Great shots from the early shuttle days

Have we seen any sign that B9 has been/is being modified with the additional hot-stage ring and the new FTS ? Right now, to me this seems to be the long pole, more than the OLM.

John_Hasler,

Musk has said that he expected approval of a new FTS to be the long pole.

ludu,

Yeah, there is approval. But I’m more talking about the retrofitting, which doesn’t even seem to have started.

Oddbin, in Why SpaceX Plans To Jettison The Interstage On Flight 4

I’m sure that this is just a temporary thing until the ring is fully integrated into future booster versions. There’s been changes to Booster that’s bumped its mass up quite a bit I believe.

I’m sure one of the videos from the known commenters noted that this means it’s a fair bit heavier but future ones reduce weight. Due to how fast they iterate and build the changes are being applied to a few boosters from now but they’ll just make do with what’s coming before that.

Such an interesting flight.

Everyone thought it was going to explode at somepoint. Even the enthusiastic and hopeful hosts were talking about how long it’s going to last. Then it made it.

Would love to see some photos of it.

But they aren’t reviving anything are they?

Engineering issue ignored by executives? Where have I seen this before …

“ Space Shuttle Challenger repeatedly launched with damaged O-rings, but it never gave up!”

“Space Shuttle Columbia is repeatedly loses cooling panels, but it never gave up!”

Until they did give up

Engineer 1 “How do we know how strong this part needs to be?”

Engineer 2 “Um. Shall we test it?”

Engineer 1 “Yea okay.” … “Oh hey we learnt something.”

Some random guy watching “Look at the fucking idiots over there. Testing things. Chumps”

Diplomjodler3,

What exactly is your point here?

dueuwuje,

I think it doesn’t need rocket science to understand the point trying to be made.

MartianSands,

The problem is that their point is nonsense.

This isn’t a long-standing problem being persistently ignored, this is a test flight designed specifically to discover such problems. They were so keen to test how the system handled problems like this that they deliberately damaged the heat shield before the flight (somewhere other than where this particular problem occurred).

The implication that this partial failure of the heat shield is damning evidence of negligence is either ignorant or deliberately deceptive

Tar_alcaran,

I’d much rather they blow up an empty mockup than a manned shuttle, but yeah, ignoring known issues isn’t great.

There’s no way he didn’t completely lose his shit in those final seconds when Starship successfully relit. His neighbours must have heard a dictionaries worth of new swear words.

shadowtofu, in Starship survives reentry during fourth test flight

That was some Columbia-level damage that Starship experienced during reentry, and yet it successfully retained control authority, completed a soft landing, and everything was live streamed. Amazing!

The booster seems to be almost ready for the first catch attempt (depending on the accuracy of the landing).

I wonder to what extent they can retrofit Ship 30 to reinforce the hinge of the flaps, and how long that is going to take? On the other hand, the ship did survive, so maybe they will just repeat the launch without any major fixes, and try a few different things? (Deorbit burn, maybe even suborbital test-mass deployment, or more aggressive tests of the heat shield?)

The next-generation Starship design has less exposed flaps with reinforced hinges already. But is it already in production?

clothes,

If it’s only the on-screen flap that had issues, hopefully that points to a minor fix instead of a major one. I wonder what sort of data they have on this. How many thermal tiles were lost on each flap? Where did the issues start? Are the other flaps alright? Hard things to track.

thedarkfly, in Starship Integrated Flight Test 4 Launch Discussion and Updates Thread!

That was incredible. Can’t wait for ground footage of the ship landing burn.

burble, in Starship survives reentry during fourth test flight

That was an incredible success and improvement. Control authority worked. Engine relights worked. Both stages for to their splashdown.

Put Starlinks on the next one!

How did the flap and, indeed, starship have enough control authority after the burn up during re-entry, to complete the soft landing?

The booster done good as well of course…

Flipping awesome outcome… Beers all around.

HootinNHollerin, in Starship survives reentry during fourth test flight

That was incredible

Tar_alcaran, in Starship survives reentry during fourth test flight

I would love to see external video of the landing. Is there any?

threelonmusketeers,

I’m not sure if SpaceX had any marine assets near the landing zone this time. I hope they did though, as the onboard cameras were a bit… occluded.

Tar_alcaran,

On the one hand, you’d definitely want a look at the landing. On the other hand, I’m not sure I’d want to be anywhere near the possible impact spot in case of failure.

Chainweasel,

They used a drone launched from a ship to the film The First falcon 9 landing almost a decade ago so I don’t see why that would be out of the realm of possibility.

Fermion,

And they have droneship landing platforms that could be used as a basestation for surveillance equipment.

Tar_alcaran, (edited )

They’re called drone-ships, but they’re more drone-barges. You absolutely couldn’t take them all the way out into the Indian Ocean in anthing but amazing weather, and they were delivered to their current home on top of another ship.

That’s not to say you couldn’t have some kind of unmanned observer nearby, but it’ll have to be something else. Any yacht with a camera and a good drone would do the trick, you don’t need to spend (and risk) millions on custom ships for that.

Well fuck, I’m speechless. Amazing test flight!
