This is the same age when I started watching Star Trek (original series). To say it had a profound impact on my interest in science and ethics is an understatement. English wasn't even my first language, but I think I picked up a lot of the themes, and my interest in science, tech and ethical philosophy continues to this day. I actually wrote this bit about introducing children to Star Trek (answer is a bit dated now): https://scifi.stackexchange.com/questions/6719/what-is-the-r...
Dated indeed, as nobody is interested in Star Trek anymore since they've actively ruined the IP.
Heck, the person spearheading star Trek vision has gone on public records essentially saying he never liked star Trek and that's why he's gonna make it more like star wars....
You're talking about the movies, and yeah, that has failed. They're talking about yet another one, and I'm baffled, but we'll see where (if anywhere) it goes.
But the Paramount+ stuff is doing pretty well. Strange New Worlds is very popular. So was Lower Decks. The last season of Picard, at least, gave fans a lot of what they had been looking for. They've got a new series coming out, and what little we know is that it has a bang-up cast. (Not that that's sufficient; Discovery did very badly by some very talented actors. But it's a good start.)
So Trek: The IP is still going pretty strong. At least as well as Star Wars, which has also been hit-and-miss.
So awesome, I hope to have kids one day precisely for this reason! One of my fondest memories is my dad quenching my curiosity (with a drawing, to boot!) of how satellite dishes work when I was 6 or 7.
My kids learning to ride a bike - the moment you release your hand for the first time and they just go and go. When my son learned checkers, and then when he beat me the first time. When my daughter told her first original joke at a family dinner and everyone died laughing.
The moments truly never stop. Every single day they amaze and surprise you, fill you with so much love and joy and appreciation.
One time Bill Gates was asked what gave him joy and without missing a beat he said his children. Nothing is greater, nothing gives you more meaning, nothing is more ultimate than the sacrifice and patience and wonder and fulfillment of having children.
There's a moment of abject horror, fascination, wonder, surprise, and pride when you suddenly recognize yourself in your children; a moment, a word, even just a holding of the head and you're staring into a mirror ...
It is a complete shift in world view. In BC (before children) you lived one way, then in AD (after delivery) you live another. Complete and utter change in priorities, outlook, experience, meaning, fundamental shift that those without children cannot understand
And people with children cannot understand what it is to live a whole life in full freedom. I'm over 50 years old and I fully love my life as it is and have never regretted my choice of not having children (and never will).
Not that my choice is suitable for everybody, but the most common choice is not suitable for everybody either.
This is a matter of personal preference of course. But the way you phrased it, "a whole life in full freedom" tells me you think it's either all or nothing. If you can't enjoy the full freedom in the last years of your life, does it take away from the previous years?
For better or worse people with kids know both lives, people without kids only know one. It's like saying "you'll never know how it is to eat an entire cake". Maybe you ate much of it, that counts for something. Now you're on to the next cake. You might bite more than you can chew but this goes for everything.
The value of this freedom is the highest when you're young, experimenting, putting your life on some track. Being "free" at 65 doesn't have anywhere near the same value as it does at 20. Once you do it (almost) all, everything else becomes more of the same doesn't it? That cake I was mentioning? The first bite tasted a whole lot better than the last.
There's no right or wrong, everyone knows their preference and personal circumstances. But your explanation felt like a knee-jerk reaction.

Compared to what? We're living in some of the best times humanity as a whole ever had. Deciding en-masse to not have kids is the irresponsible thing because it literally condemns humanity to extinction and creates a self-fulfilling prophecy. You're cursing the world because you stubbed your toe. Social media inflicted this kind of feeling a lot over the last couple of decades.

You'd have to ask them. Humans overwhelmingly choose to live so you could conclude that they prefer existing over the alternative. Happiness is very relative and you'd have a hard time defining it even for yourself, let alone for your hypothetical unborn child.

There's absolutely no evidence to support anything you said. It's your personal preference and you're entitled to it. Why don't you own your choice instead of putting it on fictitious evidence that your unborn child will be unhappy?

It doesnt compare, it cant.
But there is a catch - to have a chance for actually being a good long term stable parent (and also having and raising kids in a similar way), 2 balanced individuals need to meet and be close to each other on many levels, and then keep working on it. Something I dont see often around me unfortunately in these me-me-me times, with corresponding consequences. Better having no kids than be a miserable parent, raising another miserable generation of permanent cripples.
Just wait till you hit 60s and the pool of nice things you can do keeps shrinking dramatically, I've heard such phrases before and then heard regrets some time later.
Do your kids have Social Security Numbers yet? Let's ask Elon to use his privileged mode on xAI to have it characterize their socio economic relations among all Americans that have existed since The Great Deal, shall we?
To respond in such a moronic, unthinking, truly absurd and ridiculous way to such a beautiful comment is bizarre and unnecessary beyond human understanding
Even Steve Jobs, who was by most accounts a pretty cold fish (his many other qualities notwithstanding), said something similar. By memory, he said something like: With your kids, it's as if they carry your heart around outside of your body. Which I found super touching and apt.
"Making the decision to have a child - it is momentous. It is to decide forever to have your heart go walking around outside your body." -- Elizabeth Stone
Oh I will. My boy just turned 4, so he’s a little young for video games right now. Maybe 5 or 6? But we played spaceships in the park all evening. Looking forward to gaming age for sure!
Well that's part of what makes this interesting. Some part of it did go boom. Looked like a COPV or something exploded sometime after payload deployment
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.
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.
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.
> The push for rapid reusability seems somewhat at odds with the push for large scale production of ships.
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.
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.
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.
> rapid reusability seems somewhat at odds with the push for large scale production of ships
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.
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
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).
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.
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.
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.
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.
Are the tiles on Starship going to need replacing after flight like the Shuttle? There isn’t a permanent material that can handle all the heat yet? Serious question, my space expertise is only from KSP.
The intention is to need minimal to no replacement between flights. Part of the purpose of these tests is to figure out how to do that.
The tiles themselves work fine, but how to best mount them? where do you need them? Can you make them thinner? do you need anything underneath? what kind of gap do you need between tiles? Those are the things they're hoping to understand in these tests.
The Shuttle tiles were technically reusable AFAIK. The issue was that they were very fragile and the Shuttle for the most part could not tolerate any heat getting through the tiles (being aluminum), so every flight needed to have a perfect heat shield. Starship is a bit better on that end, as stainless steel is a lot more capable of tolerating heat and I think the tiles are a bit less fragile. Still, would be ideal to figure out how to not drop any tiles.
Would note that Shuttle tiles were never mass manufactured. The Shuttle’s shape meant lots of unique tiles. And its lack of mass production meant each tile was basically an artisanal object.
SpaceX aims to reüse tiles over many flights. But even if some tiles need replacing after each launch, that doesn’t tank Starship per se.
Maybe even throwing a used ship away as scrap metal away would work as a business case. The expensive part are the rocket engines, if they can be reused much would be won.
> every flight needed to have a perfect heat shield.
Which is a little easier to do when your craft is shaped like a plane and not a simple cylinder. The loading and positioning were easier to model and then achieve in flight.
The shuttle also flew with repair kits and glue that could be used in a vacuum. The astronauts could perform an EVA and work to replace damaged tiles and there were published plans on how to do so. NASA unfortunately figured out very late that using the Canadarm to image the bottom of the shuttle immediately on achieving orbit was extremely necessary given the icing problems of the external tank.
I thought that while the spare tiles did exist, there was never an actual safe procedure for replacing tiles (that didn't require being docked to the ISS) they were only carried to be available when the choice was between losing the entire crew on reentry or risking a crew member?
I don't quite understand how the airplane shape made it easier to model the loading and positioning? (Not saying you're wrong, just doesn't fit my intuition and I'm curious).
My understanding is that Shuttle didn't have to answer the questions about tile gaps etc because it used glue rather than mechanical attachments, if that's what you mean by positioning.
> I don't quite understand how the airplane shape made it easier to model the loading and positioning? (Not saying you're wrong, just doesn't fit my intuition and I'm curious).
You can approximate space shuttle reentry to roughly a 2d surface entering atmosphere. Because of airplane shape, the tile side faces atmosphere and the plasma goes around plane edges. Where as starship being cylinder doesn't have any separation boundary and plasma roughly goes more than 180% of the cylinder.
IR reflectivity of stainless must help a good deal for the unshielded parts. I wonder if the internal surface is painted or finished in a way to help radiate the heat away internally.
Is there any active cooling of any of the skin that we know of?
Remains to be seen. That's what they want, but it's never been done before. (edit: clarity: they do NOT want to replace them after each flight.)
They're currently experimenting with things such as actively cooled tiles (which I presume were installed on this ship, since they were on the last two).
I personally think the likely best case is that they'll have to go over the ship and replace some here and there before launching again.
Even if they don't get to a no replacement....they still already have a massive improvement over Space Shuttle. The Space Shuttle basically every tile was unique, and and the pattern was different between the different orbiters. A good bit of the months of refurbishment of the Orbiter between flights was heat shield repairs. SpaceX has already shown from when they completely retiled one of the ships. they have cut down the time to replace a single tile down to minutes instead of the hours it took with the shuttle. The Tiles are also alot more standardized so they can be more mass produced than shuttle tiles.
I think there are still a few unique tiles on Starship around joints and such IIRC, but either way, the number of tile types is much smaller for Starship.
To my thinking, the sane sequence will be launch; catch; survey and maintain (heat shield and other items); and then launch again 24 hours later if everything checks out.
And that will be an absolutely massive improvement over what we have today, let alone what we had with the Shuttle.
Landed on target in the Indian Ocean! Engines relit successfully and it touched down vertically (and then promptly exploded, which I guess was the plan :)
This sequence of events (even though expected!) reminds me a lot of the Monty Python and the Holy Grail speech:
> Listen, lad. I built this kingdom up from nothing. When I started here, all there was was swamp. Other kings said I was daft to build a castle on a swamp, but I built it all the same, just to show 'em. It sank into the swamp. So, I built a second one. That sank into the swamp. So, I built a third one. That burned down, fell over, then sank into the swamp, but the fourth one... stayed up! And that's what you're gonna get, lad: the strongest castle in these islands.
(although I suppose this ship fell over, then burned down, and then sank into the ocean)
EDIT: made it. I suppose it was meant to blow up on landing in the ocean? It would have been nice to examine the burned components — but perhaps they had not intended to retrieve it that far away anyway.
The walls are 3mm thick steel, they're very likely to buckle and tear when it tips over, the residual methane vapor gets out and there are plenty of sources of heat to ignite it.
They don't claim to have any plans of recovering the wreckage, but they have previously fished up wreckage for study, so it's still possible they decide to do that.
Maybe just some part of the construction (possibly even just the strinngers or simply some nook or cranny that is fully eclosed) got presurized or was pressurized for the whole time by just air that could not escape.
That would be fine for the fligt so far - until it started to heat up from re-entry heating. The stainless steel would be still fine if heated to hundreads of degrees, but the expanding gass could maybe make the enclosed volume to rupture ?
Or a mix of methane and oxygen accumulating somwhere and exploding - but that seems less likely to me in a near vacuum environment during re-entry.
IIRC they have pressure vessels in the lower fins with some of the gasses they need. Maybe one of those was damaged and burst. To me it looked like something blew out the bottom of one of the fins (maybe got too hot) and hit the skirt.
They announced before the flight that they intentionally removed tiles from some areas around the lower flaps specifically to get data on what happens when tiles fail, such as how much burn occurs, how quickly and what type. It appears it was successful in showing varying amounts of burn through and damage in the areas that were intentionally left under-protected.
The part that burned was damaged from early on, likely at, or right after, separation. So the integrity of that flap was already very compromised. I actually thought the flap would disintegrate on re-entry with that kind of damage. But no, they even put full stress on it, unfolding it while supersonic through the atmosphere, like a champ.
So the starlink simulators its deploying right now are empty platters that will burn up in the atmosphere from what I understand. Next missions they’ll be real statlink sats. Are these different than regular sats? It sounds like they’re able to handle more bandwidth but I don’t know.
Starship will be deploying the next gen v3 satellites, which weigh about 2 tons each. A single Starship launch with 60 of these deploys more capacity than 20 launches of a Falcon 9.
The figures they've been talking of the ideal cost per launch of starship are even more insane. I'm sure some of it is hype farming on Twitter but if they get the cost to less then $1000/kg it would be incredible.
Yes; I think it would be more accurate to say that the economics of Starship basically require high cadence launches with lots of v3 Starlink satellites (because only the big internet constellations can financially justify launching so much payload to orbit right now).
Exhilarating to see the V2 finally get its "fourth time's the charm" full success!
My top reason for wanting to visit US has flipped semi-recently to wanting to witness one of these launches. I'd hate for the Boca Chica site to become more secretive as it marches on towards production quality.
The crazy thing is there’s a public road about 200 yards from the pad that also goes right by the front door of the factory. Like you can drive right up to starbase, park, and walk around and see everything. Also, you can go past the pad to the beach and walk up on the dunes and be within 500 yards of the pad and whatever is sitting on it too. I visited a few years ago and was amazed at the scale and how everything is literally right on the side of the road. One thing I didn’t expect, it’s pretty noisy because it’s an ongoing construction site. You don’t think of that when you see the videos.
Anyone know the best way to get the SpaceX video from Twitter/X onto Apple TV?
My current method is to screen share from an iPad after starting the video on Safari. Trying to Airplay gave me audio but not video on the TV. But, the screen share has a pretty large letterbox around it, was hoping to get full screen video.
> Anyone know the best way to get the SpaceX video from Twitter/X onto Apple TV?
I don't have Apple TV but for videos on X, I download it temporarily to a intermediate server then stream using VLC [1] it's a hassle but I get great watching experience on all platforms. For now, you can stream this on VLC: https://bin.hrzn.pics/0AdLye8
Though I generally watch Everyday Astronaut's [2] coverage on YouTube.
I can't help but think of one cray thing...This is absolutely amazing to watch. The fact that there are cameras at every stage showing exactly what is happening. Being able to see the curvature of earth all in hi-def. But the entire time I watch this I just keep thinking even with all this proof you still will not convince some people that the moon landings are real and that the earth is not flat. They will say these are just AI videos used to trick people from the truth.
It just amazes me that technologies have come so far that at one end we can really show that the earth is truthfully a sphere but also at the same time technology has come so far one can claim this is just another video created by AI and is not actually true.
Yea, I'm older and remember the shuttle days. It's the video all the way to the ground that amazes me every time (well at least when the orbiter is aligned properly and not turning into a meteor shower).
Only possible through SpaceX Starlink, but technical progress aside they also deserve kudos to be so open to share some of their video streams publicly and not cutting away from explosions or burning flaps.
Blue Origin didn't show with the first New Glenn launch their payload mechanism or reentry mishaps.
Nice! I know they were intentionally stressing the flaps, but saw at least one was on fire again and deteriorating. How big an issue is this and how are they likely to solve it?
The damage to the trailing edge of the aft flaps was caused by whatever took out the skirt. You can see they are torn up and sheet metal flapping long before they start to descend and heat up. It is possible they would have held up to the heat if that hadn't occurred. I didn't see any burning through along the flap hinge like in previous flights (although they only showed direct side-on video of two of the flaps).
Could you please stop posting unsubstantive comments and flamebait and generally using HN for political/ideological battle? You may not owe $ThatPerson better, but you owe this community better if you're participating in it.
Pretty sure the DOGE intent was good, but real efforts were mostly sidelined for the Trump pony show. Thus the 'fighting' words that followed when the BBB tax cut showed up.
DOGE never tried to do good work. It was a hit and run job to satisfy Musk's ego and get rid of stuff he personally doesn't like. It didn't save much money and didn't create any efficiency.
You’ve been seriously misled or you’ve forgotten what happened. How did the illegal shutdown of USAID and the waste of billions of dollars of medicine, food, and health care for the poorest folks in the world come from good intentions? How did the irresponsible injection of inexperienced outsiders into the SSA come from good intentions? How is cancelling billions of ongoing federal contracts without cause and withholding payments for work already done an effect of good intent?
Unbelievable! Watched with my 4 year old, he was full of questions about why the ocean was turning to nighttime, what satellites are, about going to another planet, about the earth being so blue and if we “ever even knew that before”.

Something I dont see often around me unfortunately in these me-me-me times, with corresponding consequences. Better having no kids than be a miserable parent, raising another miserable generation of permanent cripples.
Just wait till you hit 60s and the pool of nice things you can do keeps shrinking dramatically, I've heard such phrases before and then heard regrets some time later.
I can understand. I have 4 small kids. The amount of freetime us near zero. I can sometimes envy your life
Do your kids have Social Security Numbers yet? Let's ask Elon to use his privileged mode on xAI to have it characterize their socio economic relations among all Americans that have existed since The Great Deal, shall we?
To respond in such a moronic, unthinking, truly absurd and ridiculous way to such a beautiful comment is bizarre and unnecessary beyond human understanding
Thanks for this. We are expecting one in two months (our first), and reading this made me happy.
Even Steve Jobs, who was by most accounts a pretty cold fish (his many other qualities notwithstanding), said something similar. By memory, he said something like: With your kids, it's as if they carry your heart around outside of your body. Which I found super touching and apt.

Warning. KSP breaks pretty much all sci fi programs when you wonder why the landing shuttle is flying towards the planet it’s going to.
Oh I will. My boy just turned 4, so he’s a little young for video games right now. Maybe 5 or 6? But we played spaceships in the park all evening. Looking forward to gaming age for sure!
If you live in a good spot, a beginners telescope might be money well spent.
I always ask mine what she’d like to do after school today.
“Let’s go to the moon” comes back at least once a week.
Sincerely hope to be able to take her, one day.
I'm amazed the thing landed right next to the Buoy, and was seen from the BuoyCam.
This has happened many times so far. Control to reach a specific landing point is quite good (when things don't go boom first)
This is definotely on purpose & quite important for the upcomming starship catching for rapid reusability. :)
Well that's part of what makes this interesting. Some part of it did go boom. Looked like a COPV or something exploded sometime after payload deployment
Was cool to see the pez dispenser door start to open and all that vapor get sucked outside.
The booster ditch was super cool, hover then just cut the engines and let it drop.
Simulating a chopsticks landing, probably.
Just saw the splash down. I think this was 100% successful test.
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.
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.
> The push for rapid reusability seems somewhat at odds with the push for large scale production of ships.
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.
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.
Still, LEO is halfway to anywhere in the Solar System, so that's exciting.
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.
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.
> rapid reusability seems somewhat at odds with the push for large scale production of ships
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.
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
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.
What's the need for tile waterproofing ?
They are extremely hydrophilic.
Thunderf00t shows various tile problems with Starship: https://youtu.be/MZUQe38SJIs?si=QAVIk7fMX1HIQETb (he's not a fan of Musk)
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).
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.
> There are plenty of equally uninformed youtubers with glowing praise for SpaceX
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.
Yes, although one booster engine failed at the start. Not a big deal. :)
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.
They said ahead of time they were shutting one booster engine down to test redundancy.
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.
that was on the landing burn. they had a engine out on the ascent.
Yes. Looks like it ignited and ran correctly for the first few minutes though.
The hype had this thing already on the Moon by now.
*Mars
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.
It's interesting to see which parts are critical at each stage of flight. Clearly those parts weren't needed by that point!
The rear flap was damaged before that explosion, not sure by what.
Yes, it was not the explosion what done it.
It looked like it happened during separation somehow.
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.
Are the tiles on Starship going to need replacing after flight like the Shuttle? There isn’t a permanent material that can handle all the heat yet? Serious question, my space expertise is only from KSP.
The intention is to need minimal to no replacement between flights. Part of the purpose of these tests is to figure out how to do that.
The tiles themselves work fine, but how to best mount them? where do you need them? Can you make them thinner? do you need anything underneath? what kind of gap do you need between tiles? Those are the things they're hoping to understand in these tests.
The Shuttle tiles were technically reusable AFAIK. The issue was that they were very fragile and the Shuttle for the most part could not tolerate any heat getting through the tiles (being aluminum), so every flight needed to have a perfect heat shield. Starship is a bit better on that end, as stainless steel is a lot more capable of tolerating heat and I think the tiles are a bit less fragile. Still, would be ideal to figure out how to not drop any tiles.
> Shuttle tiles were technically reusable
Would note that Shuttle tiles were never mass manufactured. The Shuttle’s shape meant lots of unique tiles. And its lack of mass production meant each tile was basically an artisanal object.
SpaceX aims to reüse tiles over many flights. But even if some tiles need replacing after each launch, that doesn’t tank Starship per se.
Maybe even throwing a used ship away as scrap metal away would work as a business case. The expensive part are the rocket engines, if they can be reused much would be won.
> every flight needed to have a perfect heat shield.
Which is a little easier to do when your craft is shaped like a plane and not a simple cylinder. The loading and positioning were easier to model and then achieve in flight.
The shuttle also flew with repair kits and glue that could be used in a vacuum. The astronauts could perform an EVA and work to replace damaged tiles and there were published plans on how to do so. NASA unfortunately figured out very late that using the Canadarm to image the bottom of the shuttle immediately on achieving orbit was extremely necessary given the icing problems of the external tank.
I thought that while the spare tiles did exist, there was never an actual safe procedure for replacing tiles (that didn't require being docked to the ISS) they were only carried to be available when the choice was between losing the entire crew on reentry or risking a crew member?
I don't quite understand how the airplane shape made it easier to model the loading and positioning? (Not saying you're wrong, just doesn't fit my intuition and I'm curious).
My understanding is that Shuttle didn't have to answer the questions about tile gaps etc because it used glue rather than mechanical attachments, if that's what you mean by positioning.
> I don't quite understand how the airplane shape made it easier to model the loading and positioning? (Not saying you're wrong, just doesn't fit my intuition and I'm curious).
You can approximate space shuttle reentry to roughly a 2d surface entering atmosphere. Because of airplane shape, the tile side faces atmosphere and the plasma goes around plane edges. Where as starship being cylinder doesn't have any separation boundary and plasma roughly goes more than 180% of the cylinder.
IR reflectivity of stainless must help a good deal for the unshielded parts. I wonder if the internal surface is painted or finished in a way to help radiate the heat away internally.
Is there any active cooling of any of the skin that we know of?
Ah, that makes sense!
Having seen the shuttle in person in LA museum, I was struck by how much it looked like a plane sitting on a flat heat shield surface
Remains to be seen. That's what they want, but it's never been done before. (edit: clarity: they do NOT want to replace them after each flight.)
They're currently experimenting with things such as actively cooled tiles (which I presume were installed on this ship, since they were on the last two).
I personally think the likely best case is that they'll have to go over the ship and replace some here and there before launching again.
Even if they don't get to a no replacement....they still already have a massive improvement over Space Shuttle. The Space Shuttle basically every tile was unique, and and the pattern was different between the different orbiters. A good bit of the months of refurbishment of the Orbiter between flights was heat shield repairs. SpaceX has already shown from when they completely retiled one of the ships. they have cut down the time to replace a single tile down to minutes instead of the hours it took with the shuttle. The Tiles are also alot more standardized so they can be more mass produced than shuttle tiles.
Absolutely!
I think there are still a few unique tiles on Starship around joints and such IIRC, but either way, the number of tile types is much smaller for Starship.
To my thinking, the sane sequence will be launch; catch; survey and maintain (heat shield and other items); and then launch again 24 hours later if everything checks out.
And that will be an absolutely massive improvement over what we have today, let alone what we had with the Shuttle.
I'm keeping my fingers crossed...
Landed on target in the Indian Ocean! Engines relit successfully and it touched down vertically (and then promptly exploded, which I guess was the plan :)
I thought it exploded after it landed?
Well, yes, it landed in the ocean by design and toppled over because that's what happens when you land a 50m tall spaceship vertically in water.
This sequence of events (even though expected!) reminds me a lot of the Monty Python and the Holy Grail speech:
> Listen, lad. I built this kingdom up from nothing. When I started here, all there was was swamp. Other kings said I was daft to build a castle on a swamp, but I built it all the same, just to show 'em. It sank into the swamp. So, I built a second one. That sank into the swamp. So, I built a third one. That burned down, fell over, then sank into the swamp, but the fourth one... stayed up! And that's what you're gonna get, lad: the strongest castle in these islands.
(although I suppose this ship fell over, then burned down, and then sank into the ocean)
It’s basically a direct description of the reusable booster tests.
That's the expected result for this test flight.
That was expected. It’s not meant to land on water.
It is, for the purpose of this test. Don't want it coming back down on land somewhere unexpected :)
There wa supposed to be an earth shattering kaboom. And there was.
> I thought it exploded after it landed?
It landed on the sea, there was no barge afaik.
Also here: https://www.youtube.com/watch?v=TpmTivdrQiQ
Successful splashdown! Looks like they nailed all the objectives, and not a moment too soon.
Some kind of failure in the lower engine area.
Figure it's going to burn up on entry?
EDIT: made it. I suppose it was meant to blow up on landing in the ocean? It would have been nice to examine the burned components — but perhaps they had not intended to retrieve it that far away anyway.
The walls are 3mm thick steel, they're very likely to buckle and tear when it tips over, the residual methane vapor gets out and there are plenty of sources of heat to ignite it.
They don't claim to have any plans of recovering the wreckage, but they have previously fished up wreckage for study, so it's still possible they decide to do that.
generally 4mm for the barrel sections, plus all the stringers that add rigidity to that 4mm.
It's not meant to perform well after landing in water, is how I would phrase it.
Maybe just some part of the construction (possibly even just the strinngers or simply some nook or cranny that is fully eclosed) got presurized or was pressurized for the whole time by just air that could not escape.
That would be fine for the fligt so far - until it started to heat up from re-entry heating. The stainless steel would be still fine if heated to hundreads of degrees, but the expanding gass could maybe make the enclosed volume to rupture ?
Or a mix of methane and oxygen accumulating somwhere and exploding - but that seems less likely to me in a near vacuum environment during re-entry.
IIRC they have pressure vessels in the lower fins with some of the gasses they need. Maybe one of those was damaged and burst. To me it looked like something blew out the bottom of one of the fins (maybe got too hot) and hit the skirt.
It made it, but there was some toastyness on the bottom of the lower flaps. This said, it is less bad than we've seen on the other 2 landings.
They announced before the flight that they intentionally removed tiles from some areas around the lower flaps specifically to get data on what happens when tiles fail, such as how much burn occurs, how quickly and what type. It appears it was successful in showing varying amounts of burn through and damage in the areas that were intentionally left under-protected.
The part that burned was damaged from early on, likely at, or right after, separation. So the integrity of that flap was already very compromised. I actually thought the flap would disintegrate on re-entry with that kind of damage. But no, they even put full stress on it, unfolding it while supersonic through the atmosphere, like a champ.
> Some kind of failure in the lower engine area.
The girl in NASASpaceflight video linked at top said maybe one of the three oxygen vents blew up due to some kind of buildup. Location makes sense.
Sounds like they removed a few too many heat tiles before launch.

Starship's Tenth Flight Test - https://news.ycombinator.com/item?id=45007907 - Aug 2025 (233 comments)
Everything nominal so far and payload deployment was successful for the first time. Re-entry starts at around T+0:45.
Which is in about 4 minutes.
And it splashed down successfully too.
Looks like they hit all the objectives!
Splashdown right next to the buoy!
Awesome to see it all go right.
Always an inspiring sight!
They did it. Damn.
So the starlink simulators its deploying right now are empty platters that will burn up in the atmosphere from what I understand. Next missions they’ll be real statlink sats. Are these different than regular sats? It sounds like they’re able to handle more bandwidth but I don’t know.
Starship will be deploying the next gen v3 satellites, which weigh about 2 tons each. A single Starship launch with 60 of these deploys more capacity than 20 launches of a Falcon 9.
The figures they've been talking of the ideal cost per launch of starship are even more insane. I'm sure some of it is hype farming on Twitter but if they get the cost to less then $1000/kg it would be incredible.
IIRC the v3 sats can do like 1 Tbps of bandwidth thanks to a larger antenna system?
Wow, that really puts it into perspective
Next flight should be a mass simulator of at least 100 tons to orbit. This flight was around ~10 tons to almost orbit.
The economics of Starlink basically require high cadence Starship launches with 50+ Starlink v3 satellites on each flight.
Isn't starlink a revenue generating endeavor already?
Yes; I think it would be more accurate to say that the economics of Starship basically require high cadence launches with lots of v3 Starlink satellites (because only the big internet constellations can financially justify launching so much payload to orbit right now).
Yes, they're bigger than the current Falcon 9 rockets can launch and can handle more bandwidth.
Exhilarating to see the V2 finally get its "fourth time's the charm" full success!
My top reason for wanting to visit US has flipped semi-recently to wanting to witness one of these launches. I'd hate for the Boca Chica site to become more secretive as it marches on towards production quality.
The crazy thing is there’s a public road about 200 yards from the pad that also goes right by the front door of the factory. Like you can drive right up to starbase, park, and walk around and see everything. Also, you can go past the pad to the beach and walk up on the dunes and be within 500 yards of the pad and whatever is sitting on it too. I visited a few years ago and was amazed at the scale and how everything is literally right on the side of the road. One thing I didn’t expect, it’s pretty noisy because it’s an ongoing construction site. You don’t think of that when you see the videos.
The crazy thing is that hopefully in 2-3 years a Starship launch could be as "boring" as a dime-a-dozen Falcon 9 launch today.
Anyone know the best way to get the SpaceX video from Twitter/X onto Apple TV?
My current method is to screen share from an iPad after starting the video on Safari. Trying to Airplay gave me audio but not video on the TV. But, the screen share has a pretty large letterbox around it, was hoping to get full screen video.
> Anyone know the best way to get the SpaceX video from Twitter/X onto Apple TV?
I don't have Apple TV but for videos on X, I download it temporarily to a intermediate server then stream using VLC [1] it's a hassle but I get great watching experience on all platforms. For now, you can stream this on VLC: https://bin.hrzn.pics/0AdLye8
Though I generally watch Everyday Astronaut's [2] coverage on YouTube.

Thanks. I'd like to find something that works for the live stream too.
Yeah Airplay is probably the best option, I had no problems playing it from my Macbook.
Did you pull it up in Safari and then Airplay it?
That's what I did on the iPad and couldn't get the video. I can try the Mac next time. It's not my fault driver and assumed iPad would be the same.
I can't help but think of one cray thing...This is absolutely amazing to watch. The fact that there are cameras at every stage showing exactly what is happening. Being able to see the curvature of earth all in hi-def. But the entire time I watch this I just keep thinking even with all this proof you still will not convince some people that the moon landings are real and that the earth is not flat. They will say these are just AI videos used to trick people from the truth.
It just amazes me that technologies have come so far that at one end we can really show that the earth is truthfully a sphere but also at the same time technology has come so far one can claim this is just another video created by AI and is not actually true.
Yea, I'm older and remember the shuttle days. It's the video all the way to the ground that amazes me every time (well at least when the orbiter is aligned properly and not turning into a meteor shower).
Only possible through SpaceX Starlink, but technical progress aside they also deserve kudos to be so open to share some of their video streams publicly and not cutting away from explosions or burning flaps.
Blue Origin didn't show with the first New Glenn launch their payload mechanism or reentry mishaps.
Nice! I know they were intentionally stressing the flaps, but saw at least one was on fire again and deteriorating. How big an issue is this and how are they likely to solve it?
The damage to the trailing edge of the aft flaps was caused by whatever took out the skirt. You can see they are torn up and sheet metal flapping long before they start to descend and heat up. It is possible they would have held up to the heat if that hadn't occurred. I didn't see any burning through along the flap hinge like in previous flights (although they only showed direct side-on video of two of the flaps).
Well done Elon! Very excited for the future!
Incredible.
Dude, they nailed it. Amazing.
> The flight test began with Super Heavy successfully lifting off by igniting all 33 Raptor engines and ascending over the Gulf of America.
It took me a moment to remember what the Gulf of America is. What stupidity.
You're not stupid!
It's a body of water south of Florida, Georgia, Alabama, Mississippi, Louisiana, and Texas.
It used to be called the Gulf of Mexico.
Still is everywhere else.

Pretty sure the DOGE intent was good, but real efforts were mostly sidelined for the Trump pony show. Thus the 'fighting' words that followed when the BBB tax cut showed up.
DOGE never tried to do good work. It was a hit and run job to satisfy Musk's ego and get rid of stuff he personally doesn't like. It didn't save much money and didn't create any efficiency.
You’ve been seriously misled or you’ve forgotten what happened. How did the illegal shutdown of USAID and the waste of billions of dollars of medicine, food, and health care for the poorest folks in the world come from good intentions? How did the irresponsible injection of inexperienced outsiders into the SSA come from good intentions? How is cancelling billions of ongoing federal contracts without cause and withholding payments for work already done an effect of good intent?
DOGE is the best example of Dunning-Kruger effect. A bunch of smart kids think they are better than everyone.
