Great job hosting Starbase Flyover Update Ryan, Also thanks to Jack, & Sean for the great video footage; and everyone else who contributed to the videos! OH ya and to NSF for all you do to make this happen, Thank you!!!
As always, an excellent reporting by Ryan and the crew @ NSF. Crisp, concise, information-packed. Always a tid-bit or two that I failed to notice during the week. You folks rock!
Wow, even if you knew nothing about Starship and it's booster, you'd practically be an expert after this update. An amazing amount of detail. Keep up the great work.
What a great update, especially with so much happening, and NSF catching most of it for us. Ryan, you delivered a slightly less rushed delivery in this show I must say I enjoyed a lot more. The great editing helped as well. It looks like the next 6-24 months still have a lot of development and updates for NSF to cover. Exiting times for sure. Keep it up NSF, you'all are awesome
Yeah, I think you're right. You can see how they continue onto the flat concrete at the top of the trench, where they have a very similar appearance to what I think is undisputedly tire tracks where some vehicle drove across. The tire marks are likely more visible on the slope of the trench simply due to how steep it is - it takes more lateral force from the engine through the tires to climb a steep slope (or brake while going down) compared to going over a flat area, so it stands to reason that tires would wear at a faster rate and leave behind more rubber.
@@Keldor314 Precisely, the uniform lines makes it unlikely but possible to be scorches but them continuing over the edge in the same lines is basically impossible for scorches but could 100% be tires continuing to grip hard in order to get vehicle over the edge.
If your willing to make the trip, there are some to be had along the shores "near" any splash down. Hundreds, hopefully you can find a full one. Others have.
Thanks Ryan. Good finds/supposition on the hexagon structure and likely correlation to booster 2 engine config. re. tile replacement: 18K tiles / 21 platform levels suggest that with enough people working simultaneously they could conceivably get 'er done in like a week. This ignores both availability of that many workers, but also maybe weight limits on the scaffolding and how to get materials to where needed in such a crowed work space. These guys sure know how to remove barriers,
As always, I absolutely love the detail you guys go into and this is another great update video (just catching up, as I've been away). A little constructive feedback - certainly not criticism, especially as I know English isn't Alex's first language. If you use "awaiting" you don't need the "for". "Awaiting" essentially means the same as "waiting for" so the additional "for" is redundant. A bit like saying 6am in the morning, where 6am means 6 in the morning, so the additional words are redundant. Also, I don't think "grinded" is a word. I'm happy to be corrected, but every use I can think of, including when roughing up Starship's nose cone with a grinder after removing adhesive, it should be "ground". I'm a bit surprised Ryan didn't catch these, but that's easy for me to say whilst watching from my sofa with no time pressure nearly a week after it was published!
Seeing and listening to an Intelligent discourse, from a young Englishman, who sports no holes punched through his face, has no artificial blues or reds In his hair..who knows what he talking about and has such a humble demeanour..."Hats off to You" young sir. An exemplary effort.
Another great report. A detail with launch mount - tower relationship. The mount won't be above the tower base unless they go to a tripod design - don't wan't one or two legs of the mount having more support than the others.
horrible video. SpaceX has not progress beyond Apollo 4 and spaceshuttle heat shield tech at all. total losers. Please share this dirty truth...dont be afraid like everyone else
Now we see hardware for testing a booster with 5 centre engines this is all starting to make sense. Booster V2 is needed for Artemis to reduce the number of tanker flights, and given there is room to get 2 extra engines in there, it's a slam-dunk of a way to increase the payload. Another significant advantage while improving Raptor's reliability is having 5 engines available for that hoverslam providing more redundancy for engine failures. This may also provide more attitude control during the final phase of deceleration via differential thrust. Naturally, they may still need to do the final stage on 3 or fewer engines if they cannot throttle down sufficiently with sufficient control for the hover onto the chopsticks.
Couple quick clarifications, "need" Is the wrong word, it will help to lower tankers, but its not needed. Starship and its booster dont do hover slams, they do controlled touchdowns. Also differential throttle is specifically for those which dont have gimbaling. But i appreciate how much you understand so many areas in space flight, you certainly get into this stuff quite well.
I see the logic but thats not how Spacex plays this game, others like ULA do this but Spacex are very intent on destroying gravitys face. The purpose of so much thrust on Super heavy is specifically to lower gravity losses which increases the payload possible. Since Starship is far behind its payload goal, every decision will be done with this goal as the main factor.
@@jamescobban857 For complexity and weight yeah, but Its barely more complexity to add two engines while raising thrust to weight which equals more payload due to less gravity loss. So its weight that makes less weight in the end.
12 days is a good estimate for Removal assuming Max amount of staff are occupied with Removal. But I can see them gett8ng it done completely within 21 days...these guys are machines!!
Pretty sure the 2:21 test cap was lifting up on the booster landing pins, as that is the expected use case -- pushing down on them would definitely not be a nominal landing!
Out of curiosity does anyone know how thick the steel is that being used for the corner posts and the sandwich wall sections for the base of the tower? There are so many people watching in such detail that I'm thinking maybe someone got an up-close cross-sectional photo of some of those steel parts being trucked in and might have been able to estimate the steel thicknesses.
The info is probably paywalled on the nsf website, if it's there they won't share it if you don't pay act nobody else will share it either if they are a member.
Thanks for the update! One word of criticism, a little too much time showing the speaker. Remember rule #1 of rocket broadcasts, always show the rocket. It applies here too. Always show what he's talking about, maybe just him for short transitions but preferably not since the hard cuts can be jarring. A narrator can stay just that, they don't have to be so visible. I had to pause multiple times to go back to look at what was talked about because the camera cut back to the speaker. (nothing against him at all, he did a great job!)
Watching each referb of stage 0 makes it apparent that much more work needs to be accomplished if SpaceX really does expect to launch multiple Starships each day. I would suspect we will see at least 4 stage 0s at each launch location, Starbase, KSC, and the west coast. It may also require the addition of a second Starbase somewhere on the Pacific side of the Yukatan peninsula or Panama. Later we may see one with production facilities at some place like the Philippines or Guam. The future of SpaceX is clearly flexible and filled with excitement. Go SpaceX.
great updated! umm isnt that timing to replaced the tiles based on just one person? if they have what looks like up to 20 people, working in pairs would it not be quicker? or am I being pedantic and your already factored that in?. hehe
@1:01 They view you really want to see of the flame trench is the metal bucket directly under the mount. That's the bit that would be costly to repair.
I wonder if 35 Raptors would hurt their ability to gimbal. Which would result in diminished control of the booster. Same question for 9 Raptors on the Ship.
I made the very same mental note! Since they plan to leave them all unshielded on the outer ring of engines, perhaps they plan to increase their mount position outward slightly, then shift the middle ring as well, thereby affording the Inner ring some additional wiggle room... They wouldn't have much room between each other, but I suppose it's likely they'll just all be moving in the same direction _anyways_ and don't *need* much space between them. 🤷♂️
In evaluating the Starship thermal protection system we must remember that the objective is not survival, it is rapid reusability. If the stainless steel hull is exposed to more than about 800°C it may deform, which could require a major rebuild. By contrast even the loss of a few hundred tiles could be repaired in a few hours.
Longer term they shouldn't be replacing/repairing tiles at all between flights with rapid reusability, it should be rock solid and not need an ablative (non-reusable) backup. I understand this is still being iteratively improved, but instead of actually solving the reusable heatshield problem it seems like they're just creating more stopgaps. I personally think a tile solution is fundamentally flawed for rapid reuse, but if anyone can figure out a way to make it work it's SpaceX. I'm concerned though.
It makes me wonder why they don't use a somewhat thinner tile set against the hull, and then offset a second layer, so the outer layer covers most of the seams that the inner layer has. It would make a LOT of sense as it would cover the seams, and even if the outer layer tile popped loose, there is an inner layer there. Another option would be developing an outer spray-on layer, so the seams are completely covered/filled, making the outermost shell much stronger, as it would tend to be one piece, and the tiles help hold its many fellows in place. Even would be better might be a combination of the concepts - two off-set layers, with an outer 'sealing' coat that is ~meant~ to be oblative. How about it Elon?
I may be misunderstanding the physics, but if the plasma created during re-entry is positively charged, why can't they generate a magnetic field to hold it away from the surface of the craft?
Someone suggested doing that after IFT3 in the What About It comments. I thought about further just a few days ago and my conclusion is it probably wouldn't work out... My suspicion is that the sound shockwaves, combined with the fragility of the tiles, will result in most/all of them being destroyed. 🫤 So it's likely faster and cheaper to just do the refurbishment each time, and applying a new coat of whatever "paint" is applied. It'd be interesting to know what they *_are_* coating it with... Because in the performance automotive scene, you can get your exhaust headers/manifold parts ceramic coated. Which these coatings are resilient enough to withstand the exhaust glowing *red hot* during operation, as well as them cooling back down to ambient temp afterwards, and have it survive over many heating and cooling cycles. However, it is also kinda fragile, where dropping, say a wrench, on it will chip it. So it's possible that it, too, would not hold up too well. It wouldn't surprise me if what they're coating it with is ablative, only having to last long enough for those 10-15s of engine firing before everything has cleared the OLM... Just long enough to pregnant the metal from being damaged. [/speculative ramble] 😅
Curious, had a thought ..if coming back from the moon is too hard on tiles could a rendezvous with an ion drive sun/battery powered intercept/docking tug step be added to slow it down to low orbit velocity. Where is Kerbal when I need it.🤔
Do anyone know why they replace the hold down clamps after each flight ? How do they take damage, as they retract instantly after liftoff. Flames should not even burn them 🤔
I don't think those are scorcharks at 1:05. Many sets of parallel black lines track over the right edge of the flame trench and continue on.... they look lime tire tracks.
Why don’t they launch vertically for the first 450m so the tower doesn’t get scorched as much? This would keep the exhaust plume more in the centre of the OLM.
There was SO much great info in this SB update. Gotta send something to thank you for it all. I was mesmerized by this episode!

Ive always wondered if you could launch over a pool of water and somehow convert the heat into steam for added thrust.

All this material sitting around outside at Starbase, low & close to shore. I hope they have a plan in case the area gets hit by a hurricane. 😮
Hurricanes don't usually go that far south.
The “scorch marks“ (on the flame-trench) that you mentioned are tire marks.🤦🏻
XD! 🤣
I"m sure this question has been asked before so forgive the repeat. When are they planning to begin construction of the second OLM?
It makes me wonder why they don't use a somewhat thinner tile set against the hull, and then offset a second layer, so the outer layer covers most of the seams that the inner layer has. It would make a LOT of sense as it would cover the seams, and even if the outer layer tile popped loose, there is an inner layer there.

How about it Elon?
I may be misunderstanding the physics, but if the plasma created during re-entry is positively charged, why can't they generate a magnetic field to hold it away from the surface of the craft?
I wonder if they could use some heat shield tiles on parts of the OLM? 🤔

Why don’t they launch vertically for the first 450m so the tower doesn’t get scorched as much? This would keep the exhaust plume more in the centre of the OLM.
Surprised there's not more solar PV panels being installed on all the rooftops. And megapacks.
Just FYI for NSF and others, the pronunciation of the new crane being assembled (Demag CC8800) is typically "CC eighty-eight hundred."
July will be 5 years since the first tethered hop of Star Hopper.
Why can't they use some kind of interlocking tiles?
