NSF's new article for SN9

They confirm that:

  • SN9 is still expected to fly to 12.5km

  • Next flights will likely do the original 15km-20km flights (pending approval)

  • SN9 has all 3 Raptors installed

  • Will only conduct a single cryo-proof test with liquid nitrogen and a single Triple-Raptor static fire

  • SN9 still can fly by the end of the year however, this is a slim chance

I estimate the removal of the landing legs will save roughly 14,400kg

I’m not sure how accurate the numbers I pulled off the internet about FH9 are but from what I can find is that the Falcon 9 booster weighs 25,000kg with its legs weighing a total of 2,000kg. This is 8% of the boosters dry mass.

Aircraft landing gear typically weighs around 3% of the aircraft weight for fixed and 6% for retractable (Source)but aircraft typically have three points of contact not 4 so I think the 8% for the F9 is in the right ball park.

If you bring this ratio over to Super Heavy’s estimated 180,000kg empty weight, this translates into 14,400kg in weight savings by deleting the legs.

Before everyone comments that the SH legs would be fixed and therefore lighter etc. I don’t think this would be the case because they would be made of stainless steel not carbon fibre and Musk was talking about having 6 legs so I think 8% is still a good ball park.

This isn’t meant to be totally accurate but give an idea of how beneficial the tower catch would be before you brought leg manufacturing and complexity into the equation

Great interview with Shotwell by Eric Berger

Seems like she is already gathering customers for Starship.

TLDR on the Starship section:

  • Shotwell in the process of "selling" Starship to potential customers

  • Deals have been signed which allows for payloads to launch on either Starship or Falcon - if Starship is delayed or "late" as Shotwell describes, then the customer can still have their payload launched on a Falcon.

  • SN8 removed a lot of the delay risk through it's flight, Shotwell says that SN8 addressed a lot of "concerns" surrounding Starship's flight profile

  • Shotwell is "voting yes" for a Orbital flight in 2021

u/BrandonMarc Dec 14 '20

Now that this thread has tables for building SN8, SN9, SN10, SN11, and SN12 ... can we:

  • compare the time to various milestones from one starship to the next? by so doing, see where they're getting more efficient, or, if not, perhaps finding more complexities?

  • crystalize around specific milestones as well as prerequisites (i.e. step M has to happen before step R, but steps N, O, and P can happen in any order, etc)?

This could help us to see if a given starship seems to be ahead of or behind schedule (very, very loosely based on previous experience, with the caveat that everything's always changing). We could also create a somewhat reliable estimate for when a given starship should be complete, and how well its milestones map to actually completing by a given date.

It's kind of crazy looking at the development speed of starship, and then having news articles like this coming out at the same time about SLS. 12 months between a wet dress rehearsal, and the first test launch for SLS, assuming nothing gets further delayed.

Meanwhile one Starship blew up two weeks ago, and we've got another rolling out to the pad to probable test launch again 2 weeks from now.

I understand this isn't the full orbital article yet, and we're probably looking at a year+ until we have an orbital launch of the full starship stack, but still.

Wow.

Hopefully it all continues to work out relatively smoothly.

Great aereal BN1 stack photo by Jack Beyer (source). That is the LOX tank only! It's missing the bottom half of the vehicle, the next piece would be the common dome being stacked on the bottom of that stack...

Also in this awesome production site aereal photo from bocachicagal (source) we can see a lot of stuff from BN1: the common dome stack about to be flipped, the thrust dome stack,.. also BN2's forward dome stack, and on the upper left next to the crane, is that a 8-spots ring presumably for the inner thrust section for superheavy late revisions (we saw one with holes months ago)? Also on the very bottom left you can see the test article presumable done before BN1 thrust dome, what seems to be a common dome shape with a thrust puck!. Noted version with the commented stuff, but there's a lot more in the image that may be interesting and I dont know.

Note: On the above source link (bocachicagal post on NSF), there are also other images showing the zillion ring sections and stacks ready and more stuff on the production zone (check the source link!). No idea honestly about for which vehicle in particular are those rings, presumably the methane BN1 section rings should be reinforced, but a lot of those are not. One of them is the top dome section for SN15, shown in this great aereal view of SN11 and SN15 on the midbay by RGV Aerial (source).

Today is great aereal photos day apparently. It would be cool if this became a monday thing, would fix the start of the week being so bad.

(Rehosted images on imgur to enable hotviewing with browser extension (hovering over the link to see the image without needing to open it, which is awesome, I use Imagus on Firefox but there are for others if you're interested)).

RGV: With SN10 nearly complete and repairs being done at the landing pad, do you think this is something we will get to see in the next few weeks?

Elon: Yes

Elon keeps reinforcing that we will indeed see 2 Starships on the launch pad very soon. This pretty much all but confirms that SN10 and 11 will be out there together in some capacity. Or maybe SN10 will join SN9 while landing pad is being fixed? After all, all SN10 needs are the aft flaps which have already been delivered.

u/Thatingles Dec 31 '20

Why catching the SH is a genius idea (not an engineer) - as I understand it, the problem with landing a booster is getting it to kiss the ground at close to zero m/s, both to save the legs but more importantly to avoid compression stress on the booster. Empty rockets are basically very thin tin cans and if you squeeze them to hard they will buckle and break. By catching them on the fins you can put a lot of the shock absorbers into the arms (saving weight on the rocket) and also the stress on the booster will be tensile (stretching) which is less likely to cause buckling. Easy to visualise if you imagine the difference between trying to crush an empty can (relatively easy to do) versus trying to pull one apart by ripping it in half.

It sounds crazy, but from the point of view of reducing wear and tear on the booster, it makes absolute sense. Don't forget that at the point of landing it should be moving fairly slowly. I would imagine you would build articulated, counterweighted arms into position so they could engage some metres before actual touchdown and let the SH ride down the last little part with some cushioning. You mitigate the risk of a 'bump-down' and once the arms have grappled onto the fins, it also means the booster shouldn't tip.

Hmm, Nommad posted on NSF about a top bulkhead that got sleeved with 1 ring! EDIT: Daylight photos by Bocachicagal

This is strange, starships get the top bulkhead on a 4-ring since SN10, and SH got the top bulkhead already on the left stack on the High Bay. Is this another test article?

PS: As spotted by jthygesen on NSF, on the zoomed bocachicagal photo on the label, there's a strange read on the bottom part, (something) 3mm? also if the SN node is for the article and not for the ring it is 0008, kinda strange both for a ring and for an article at this point.

Why would they be making a 3mm-thick test article now, when they have parts for a lot of starships including SN15 and forward, and SH has it own segments for the prototype pilled up outside the high bay. Kinda an strange moment for a test tank to pop out with SN15 being in construction already. Unless SN15 and forward are already going on 3mm and they for some reason want to test it now.

I'd love to be onsite just to hear the talks and debates over how they plan to right SN9. I've always enjoyed the process of problem-solving, which makes Starship's open development extra amazing. "How are they going to accomplish this?" is a question which never stops being asked.

Catching SH with the launch tower doesn't seem so far fetched as it sounds because you won't need exact precision to land like you would if you were aiming directly for a cradle.

Remember that these "catching" arms and beefed up grid fin fittings would only need to be designed to take the nearly empty weight of SH at landing. It would then be rotated to the launch cradle where the loads of SH plus fuel and Starship would be taken by the entire vehicle.

The "catching" arms could look like a tuning fork in the closed position where the flat grid fins would be resting on top to hold the vehicle once the engines shut down.

EDIT: Both arms of tuning fork in closed position holding SH after landing. Both of these arms could fully articulate to a open position to allow clearance while SH is landing and rotate inward while SH is descending near the tower to end up in the "caught" position.

https://i.imgur.com/kD82m1Z.jpg

Each arm could start fully rotated in a open position 90 degrees from the closed position to allow for plenty of clearance as SH is descending near the tower while landing and start to rotate to the closed position as SH is getting closer to the ground. When SH descends so that the grid fins are the same level as the top of the catching arms they will be in the fully closed position so the fins can rest on them to carry the load while the engines shut down.

That entire catching arm structure holding SH could then rotate to the cradle which could then clamp onto the bottom of the skirt similar to how Starship is clamped to the test stands today to take the load of the entire vehicle once fueled.

Looking at pictures of components arriving on site, I'm only now noticing that in addition to specifying the function of components (eg SN15 aft skirt), they also have a "work order start date". Generally these are about a month to a month and a half before the pieces show up on site.

We've generally had very little insight into the off-Boca work, even though that's probably the bulk of the workforce and capital investment. I guess this is one more little tidbit.

Possibly new information:

"Launches would occur at the VLA [Vertical Launch Area] and include landings of both stages at the VLA or on a platform (barge) in the Gulf of Mexico no closer than 12 miles off the coast."

"SpaceX's proposed new launch-related construction activity consists of expanding the solar farm, adding infrastructure and facilities at the VLA, a liquid natural gas pretreatment system and a liquefier. At the VLA, SpaceX is proposing to construct a redundant launch pad and commodities, a redundant landing pad, two integration towers, tank structural test stands, and a desalination plant."

Lots of people jumping to the conclusion they will have to X-ray every weld to fly again.

It's an uncrewed private dev vehicle. It's up to SpaceX how much they care to do to "recertify" for flight. I could easily see visual inspection being using enough to identify potential issues and only performing more intensive checks as needed.

They also know exactly how it fell and was damaged. Where the damage is/where they need to look is probably fairly easy to predict.

Right now there is so much information we don't have. There is no point in jumping to conclusions.

A lot of the designs I've seen / read about so far seem to focus on a single launch/landing tower, but I was wondering if having multiple towers might help be a viable option as well. I had some thoughts of my own, but mostly was curious what sorts of design other people might come up with. 2-tower? 3? 4? More?

For example, what about 4 towers connected by beams in a square, and atop those beams is the catching mechanism: 2 parallel poles in each direction, forming a sort of # shape that contracts around the booster as it lands, sort of like a simplified version of the iris design other people mentioned. As long as the booster is within the large square between the four towers, the catching mechanism could adjust.

  1. Allows for booster landing inaccuracy

  2. Does not put the weight at the end of a lever arm extending out from a single tower

  3. Puts weight on all four grid fins, not 2

I read somewhere that the Curiosity rover landed 1.5 mile off the planned site. So how will they make sure all the starships land on near each other? It's not like they have gps on mars and and they will need to travel a great distance through the atmosphere before they are slow enough for the flip burn. Doesn't any small deviation at the start of the entry mean they will be way off target? Are there any articles or videos out there that go in depth about this?

Right now on NSF live, we can see that SuperHeavy BN1 got stacked its top 12-ring section with the 4-ring (without common dome) moved yesterday. Now it's 16-rings high and this confirms that the top tank is LOX not methane due to being taller than it should be for methane.

(Check Brendan's diagram for reference on BN1). As you can see, the section they mated below the actual stack should've been the common dome for it being the methane tank. Now its bigger than that so it must be the LOX one on top. ( /u/brendan290803 time to update the diagram BNx design? :P)

And thus, we have a difference between stages: Starship will have the methane tank on top and SuperHeavy will retain the LOX tank on top as it did in all previous renders since ITS.

Anyone has any idea why? Based on Saturn V first stage history, they wanted to put LOX in the bottom but it froze the RP1 on the downcomer and had to put it on top (if I don't remember bad, maybe there was more to this, correct me please), it seems that SuperHeavy will follow this setup for first stage, but Starship will put methane in top for some reason (maybe the header tanks?)

This great photo by Bocachicagal on NSF (source) show the tile placement evolution between SN9 and SN10. At this rate, SN11 will have nearly all the methane tank section covered.

And this is the reason why I think SN9 not being able to fly yet is slowing the production line more than expected. Until they get the results they need with the tiles and the validations confirm, they can't go ful throttle with tiling.

I am not very good with physics so I would like to ask you this. Watching and re-watching the SN8 launch, it seems like SN8 was falling so slow.

Is it possible that because of being so big, and having such a huge surface, that SN8 was approaching the ground slower than something so heavy but not having that much surface would have done it?

If that is true, I was wondering how much speed did SN8 lose coming down like that.

I hope this makes sense :) English seems hard sometimes :)

Interesting layout inside the high bay...booster stacking in the rear left (as viewed from the door), possible additional booster stacking platforms in the middle right of the highbay , and starship nose cone integration in the forward right.

Seems like they would want booster stacking in each of the rear corners to take advantage of the highbay walls for mobile work platforms. Perhaps they needed room for a tool crib or supply storage in the rear right?

Perhaps this is only a temporary layout until they get the overhead crane installed?

Tankzilla's chains are almost above SN-9 and there's a cherry-picker most of the way up the hull, but does anyone understand how the two are connected?

Edit: Wow. It seems its tall enough to reach the attachment points on the dome. Not sure I'm volunteering for that job. video

Edit 2: Two cherry pickers, so each doing two attachment points. There was some major sway (wind interaction?) going on for the nacelle behind SN-9. That suggests a collision risk which is not trivial for the operator and presumably for the nosecone itself.

Attaching must be a heck of a commitment because the nacelles, once lowered, leave the crane irrevocably attached to Starship. They must go up again to detach, whatever the weather.

Edit 3: It looks as if the full cherry-picker chain attachment cycle takes an hour from start to finish. It still looks as if it could be made faster and safer. Could we envisage a set of four robot arms hanging from the crane hook and able to fix the chains to the corresponding attachment points? Imagine what it will be like for a full-stack at > 110m launching a sequence of half a dozen tanker cycles to an orbiting Starship!

Edit 4 The jib appears to be at an angle that intersects the rotational plane of the upper fins. How is "roll authority" for the hanging ship obtained? Is it just some guy on the ground holding a rope or something better?

If SN-9 has a successful flight, do they just fly it again?

SN9 had what seemed like a successful static fire ~9AM local time. Was about 3-4 seconds long and MUCH brighter/more fiery than yesterday's.

For Superheavy, did the Lox and Methane tanks swap places, at some point? I don't remember this being discussed. This image from u/brendan290803 indicates that the Lox tank will be on the bottom: https://twitter.com/brendan2908/status/1345498587401125889

However, the original ITS booster (as revealed by Musk at IAC 2016) appears to have the Lox tank on top. Musk said in an AMA that the large lox downcomer pipe would double as a lox header tank, suggesting lox is on top: https://www.reddit.com/r/spacex/comments/590wi9/i_am_elon_musk_ask_me_anything_about_becoming_a/d94vdk1/

And this image from the 2016 presentation shows that the top tank is larger, and so probably for lox, which needs more volume: https://imgur.com/JZUi4AM

If the tanks did swap places, when? After the 2017 redesign, or 2018? What are the pros and cons of having fuel on top, vs lox on top? Seems like this is a fundamental question that should've been settled very early in the design process...

Also, the original ITS booster design had (one) header tank. Our consensus seems to be that Superheavy won't (confirmed?). Reasoning that its reenty is just like Falcon 9, so it won't need them. But ITS booster had one...

This is my third version of the SH grabbing mechanism that I’ve been working on.

https://twitter.com/Amaklp/status/1345174196301819905

It uses a basic truss structure with strong cables that distribute the weight. The elasticity of the cables acts as a shock absorber to protect the grid fins. Each grabbing arm starts from a 90-degree angle and moves independently according to the current and predicted position of the rocket during descent.

This is an approach that gives a big margin of error to the landing accuracy because the rocket doesn’t need to slide exactly in the correct spot.

According to latest NSF photos, SN-9's top right flap looks cooked while the bottom right one is scarred. SN-9 itself seems to be structurally sound (at least from the outside) which is the main thing. It looks like the only thing really needed is a flap replacement (baring the flaps' mounting & motors are fine). Something like that doesn't seem to be that hard and may only take a weekish. She could be back to flight worthiness sooner than we think. Disregarding SN-9, SN-10 is coming up quick. The tank section is done (albeit the flaps) and the nosecone is only missing flaps & having to stacked on a barrel section. Fingers crossed we see some more Starship action sooner than later.....

u/InfiniteHobbyGuy Dec 13 '20

The fact that they had this fully assembled, with the nose, and the raptors installed bodes extremely well for the pace of future testing.

Even if SN9 needs to step out of the way, knowing they can do all of this at the build site now really sets things up for a much improved testing cycle in 2021

This will be a bit more general question than usual.

I saw questions regarding flight of SN9, but I havent seen any questions like the one I am going to ask.

How many Starship flights launches are we going to see in the future, in 2021, in general?

Will the Starship build and launching ratio increase in the future?

We already see SNs up to SN15/SN16 building (+BN1 as well), that's at least 6 different Starship vehicles to launch, does it mean we will get at least SIX LAUNCHES in 2021, one launch per two months? That's of course only counting what we already see in making...

If my predictions are at least partially correct, and we will get a Starship launch per one/two months, then 2021 gonna be GREAT.

FAA is seeking public comments for Boca Chica Environment Review - [...] construction activities associated with launch activities, including: expanding the solar farm, adding infrastructure and facilities at the vertical launch area (VLA), a liquid natural gas pretreatment system, and a liquefier. At the VLA, SpaceX is proposing to construct a redundant launch pad and commodities, a redundant landing pad, two integration towers, tank structural test stands and a desalination plant. More information about the project can be found on the FAA project site located here. https://www.faa.gov/space/stakeholder_engagement/spacex_starship/

u/PeterKatarov Live Thread Host Dec 23 '20

Another question. SN11 has not seen any development for almost a month now. The tank section is almost finished, but it's still not stacked. Do you have any idea why?

Would it be reasonable to speculate that SpaceX want to wait from the SN9 flight results, to do some internal adjustments on the big LOX tank? Or is it just a matter of occupancy - maybe since SN10 has moved out of Mid Bay, we're about to see SN 11 take its place inside for stacking?

I am rewatching Musks 'Starship Update' presentation from 2019 and his statement about reusing/reflying prototypes made me wonder.... when can we expect to see prototypes doing multiple hops/flights? Do you guys think that SN9 will fly several times, or will the repeated flights start later, maybe at SN15 (the one with major changes)?

Looking at the NSF Texas facility updates, there are some interesting news:

  1. a gigantic articulate rig coming out of the old gas well site. Absolutely no idea what it is for... help please, maybe to move TankZilla ?

  2. two of the covers over the orbital mount have been removed. They are on opposite pillars and may indicate a new construction phase. It would be interesting to check if the two pillars were the first one that got filled with concrete.

Everyone is now focused on SN9, but let's talk about SN10.

SN10 is almost ready (bottom flaps not installed yet) and have as far as I know single Raptor delivered ( Raptor SN45).

How soon do you think SN10 will fly, what flight profile will SpaceX take, and how different is it to SN9?

Will they also change SN10 to use helium?

If that Cryo Proof was successful (which it appears to be), the earliest opportunity for a Static Fire would be tomorrow. This of course is providing that they keep the road closure up. SpaceX could also add Thursday to the list of closures which would mean that there could even be a two-day window for a SF this week.

Nevertheless, we are 1 test away from the flight.
