Just saw the splash down. I think this was 100% successful test.

kersplody 2 days ago | parent | next [-]

Not quite, but it's a major milestone. Still quite a bit of work to go on the rapid reusability part (burnt flaps, oxidized body, missing tiles, tile waterproofing). Starship might actually deliver payload to orbit on flight 11.

It accomplished all the goals for this flight. That’s 100% successful

They mentioned in the stream they were intentionally stressing the ship on reentry.

But yes, “rapid reusability” is a ways off. I expect they’ll be spending weeks inspecting and repairing ship and booster before reflight for a few years, but they’ll drive it down over time.

TBD how “rapid” the reusability ends up being in the end.

dotnet00 2 days ago | parent | next [-]

The push for rapid reusability seems somewhat at odds with the push for large scale production of ships.

It seems like if they can get boosters to rapid reuse (a much easier goal), and churn out ships at sufficient scale, they can afford to take time inspecting/refurbing each ship as part of a pipelined approach.

ACCount37 2 days ago | parent | next [-]

The stated goal was always to have a lot of ships, and also to have them be reusable.

Starship is a fuel-hungry beast - it can get to LEO by itself, but it needs a lot of tanker launches to go beyond. And if your goal is a Mars colony, you don't want to be limited to one launch per launch window.

timeninja 2 days ago | parent [-]

Still, LEO is halfway to anywhere in the Solar System, so that's exciting.

HPsquared 2 days ago | parent [-]

Also you can assemble things in LEO from multiple launches. Once you're up there, you have a lot more freedom in terms of size and shape.

If "rapid reusability" was a proxy goal for maintaining a given launch pace we wouldn't need any of this.

We could just construct 200 Space Shuttles and spend months refurbishing them after every flight, and still send one up every week.

The goal is to drive down launch costs, time is money, and a system that requires time consuming refurbishments is more expensive.

Mars transit takes far longer than one week. And their plan is in orbit refueling so getting a single starship to Mars takes more than one ship.

Elon always talks about a city on Mars but seeing for the first time the gargantuan size of Starfactory it dawned on me that SpaceX are true believers. It is still a big IF, because the dimension of the mission is absolutely bonkers, but IF the goal is to send every two years hundreds of Starships to Mars (everyone needing around 3-4 tanker missions) you need large scale production of ships.

Ten years ago every expert said a hundred launches a year was utterly impossible. Five years ago they said it was unlikely. SpaceX have launched more than a hundred times this year already.

Anyone who thinks they can’t do stuff is not seeing the whole picture.

paulhart 2 days ago | parent | prev | next [-]

Their scenario is that the ships are mostly going to be "fuel mules" to ferry propellant to the ship that is destined to go somewhere (i.e. Mars) - so if you want an armada to travel to another planet, you need a much larger fleet of supply vehicles to prepare your armada. Hence the need to mass produce them.

As you say, they reïnforce each other by speeding up the learning curve and deployment of learning to the real world, serving as both a bolstering of the product and experimental validation.

gibolt 2 days ago | parent | prev [-]

Not at odds at all. It doesn't matter how fast you can make them if each one costs $5-10 million. Much better to amortize that over 100+ flights and not waste the booster.

Once the tanker version is needed, a ship ship could go up 5+ times a day. The logistics of backfilling a pad with a new ship is much more involved

BurningFrog 2 days ago | parent | prev [-]

The ship and booster both sank in the ocean as planned, so there is no inspecting and repairing phase.

I think that work can be done quite well based on all the footage and other collected metrics.

rlt a day ago | parent [-]

I didn't mean this ship and booster, I mean in a year or so when they're done with the test phase and frequently launching Starlink satellites on Starship.

What's the need for tile waterproofing ?

imnotjames 2 days ago | parent | next [-]

They are extremely hydrophilic.

Mildly interesting to be exposed to the world of 'YouTube engineers' who are derisory of the real-world engineering success of SpaceX. Informed criticism is fine but when you're just openly calling a world class engineering company 'stupid' then you deserve to be ignored (except, obviously, by everyone suffering from MDS).

foxglacier 2 days ago | parent [-]

Thunderfoot is a long-time Musk project hater for some reason. That's now his specialty which probably appeals to his audience. There are plenty of equally uninformed youtubers with glowing praise for SpaceX. Just like the real news, people divide themselves into bubbles of whatever reinforces their beliefs.

Definitely true

> Just like the real news, people divide themselves into bubbles of whatever reinforces their beliefs

Hopefully HN can be better than that and be a place for informed criticism or informed praise from whatever provenance

That guy is so annoying.

Geee 2 days ago | parent | prev | next [-]

Yes, although one booster engine failed at the start. Not a big deal. :)

rlt 2 days ago | parent | next [-]

The nice thing about SpaceX’s rapid iteration philosophy (and having Starlink as its first “customer”) is that they can account for engine unreliability by building extra margin into early launches, fly with reduced payloads, collect data on failures, and improve the reliability over time.

imglorp 2 days ago | parent | prev [-]

They said ahead of time they were shutting one booster engine down to test redundancy.

itishappy 2 days ago | parent | next [-]

They did that too, but they also had an early engine failure. No big deal, they're redundant, and the booster they caught during flight 8 suffered worse.

ericcumbee 2 days ago | parent | prev [-]

that was on the landing burn. they had a engine out on the ascent.

indoordin0saur a day ago | parent [-]

Yes. Looks like it ignited and ran correctly for the first few minutes though.

"An uncrewed test flight was planned for 2025 to demonstrate a successful landing on the Moon which has since been delayed." https://en.wikipedia.org/wiki/Starship_HLS

Still they are making good progress if a bit slower than that.

A composite overwrapped pressure vessel (COPV) seems to have exploded on the upper stage during reentry. It did significant damage to the rear flap and it made some dents in the engines too.

HPsquared 2 days ago | parent | next [-]

It's interesting to see which parts are critical at each stage of flight. Clearly those parts weren't needed by that point!

gpm 2 days ago | parent | prev | next [-]

The rear flap was damaged before that explosion, not sure by what.

rubzah 2 days ago | parent [-]

Yes, it was not the explosion what done it.

It looked like it happened during separation somehow.

chasd00 2 days ago | parent | prev [-]

Another copv failure? That’s what ripped open the starship during the ground test. Wtf I suspect that sub won’t be making copvs for spacex any longer.
