Primary reason for the curves on the OLM pieces inside is exactly what Das said. It’s to ensure no single point of failure develops. A square corner will tend to be a stress point and start a crack that then runs through the entire section. Rounding eases and spreads the strain therefore no cracking. In some cases, such as aircraft aluminum, if you get a stress crack at a point which will relieve some of the stress, but you don’t want it to go all the way to failure, you put a small hole at the end of the existing crack. It’s called “stop drilling”. The hole being round has a lot of effect relieving any remaining stress.
I have to say I appreciate the 'behind the scenes' style comments about the cameras, framing, wb etc... Just like the narration, it adds an additional element to the video.
Thank you thank you thank you for the two audio tracks! My sci-fi futurism ASMR is back and I love you all. I also love that so many people enjoy the commentary. NSF is top of the heap becusae you keep trying new things and innovating.
SPMT's are not usually described as a number of SPMTs, because as you said the system is modular. The usual way to describe them is "Axle Lines". At the end of the video, the SPMT was was using 16 axle lines, and there were 2 sets, so it would be 2x 16 axle lines carrying the booster stand. The smallest element of SPMT is 4 axle lines (plus a power pack) so when connected together the transporter will have axles in multiples of 4 (8, 12, 16, etc)
Thanks for this latest video! I think the lift at the end with two looped slings was because the item itself was light, and the sling contact was at some sort of ring, itself fairly strong and stiff (so not at risk if compressed).
always have round corners to openings the de Havilland Comet had square windows they started to have stress fractures very quickly and there was some crashes because of it
The latest thinking on the Comet 1 failures was the windows were not the main failure point. Search for Mentour Now!'s video "YOU have Misunderstood The De Havilland Comet. It Wasn’t the Windows!" for the reasoning. That said, when I design loaded structures I do include transition radii, it's simply good practice.
@@DebraJean196 hi no my dad is a huge plane nut think i've been to every uk air museum when i was a kid and it rubbed off , not complaining i do like all forms of flight
Glad to hear Das again. Except for the intrepid lives, he's been rare online these last month! Too much work I guess, and for our pleasure. Thx to the team, as usual 🤠
"Untitled Nosecone"... KSP flashback. The rounded corners are to prevent stress cracks. They are much stronger than square corners. As you mentioned, Das, this is the same reason they do that in ship construction.
The rounded corners on steel pieces avoid stress concentrations on a single point. Sharp points are called 'stress risers'. The reinforcements on the chopsticks are all curved for the same reason, to spread loads over larger areas.
Hey, those tiny doors and the shape of the glass around them look like a perfect match for Hopper. Maybe they will put hopper there so you have to walk under it to get in the doors?
Regarding the glass doors at the Starfactory, it's possible that all of the glass can be opened in the same way that wall panels in large conference rooms can be moved around to change the size of the room.
I know SpaceX is focusing on catching boosters at the moment, and thats fine but one thing thats gotten really annoying is that many including SpaceX seem to have forgotten Starships can't land on the Moon or Mars without landing legs. Which requires significant development/changes to the ships. Why haven't we seen or heard anything about progress in that critical area? Catching a booster is fine, but catching the ships does nothing for landing on the moon and Mars. Obviously SpaceX needs to make development/testing landing legs a serious priority or Starship isn't landing on the Moon or Mars anytime soon. So until we see any progress in the area of landing legs. It makes no sense for anyone to make claims of Starship landing anywhere. Unless they are talking about landing leg development tests on earth.
My wife and I were coming down the freeway the other day and as we passed a semi with a flatbed trailer, I notice a weird shaped pipe assembly on that trailer and said "I bet anything that that pipe was going to Star Base" and there, at the 1:30 mark, I see it just under the crane! I've seen many rolls of stainless steal heading that way and but this is the first big chunk of "something" LOL I've been watching the water tanks since before Hoppy flew and then moved here from Hawaii to be closer to the action.... Got here just in time to see #10 fly, land, and then blow up from over at the park at SPI. Heady times!!
10:08 the roundness makes it spread out structural stress evenly unlike a sharp corner where it concentrates stress on a very small area. Same reason why we dont see square windows on airliners (at least on a modern one.)
1:54 Parking Garage: Typically you would treat the south & west facades with an expanded wire mesh to stop heat gain from the sun but still allow air flow. Painting it black is the opposite of what you should do in this kind of heat but it matches. The new studs on the exterior looks like they will be solid panels of some sort based on the spacing but it is confusing.
The OLM piece at time stamp 9:40 is a big piece of steel. The flatbed trailer is flat, so it's close to maximum load, in the range of 45,000 to 50,000 lbs.
Yes in structural steel a radius cut is stronger and less prone to cracking than 90deg cut and for the little added weight is minimal compared to added strength
I think they’ve already said it will be incorporated into the booster in the future, so no need to burn time and money working out a parachute system now.
When are they going to put landing legs on both starship and booster. They should just put them on now and stop just letting them drop in ocean so they can be examined and make a better inspection. Starship is going to need landing legs regardless.
In the close up of the ship engine bay, we can see another pipe running down the inside of the skirt, with a bend at the end, like a drainpipe. What is that?
What extra protection was added to Space Shuttle engines since they projected out back? Did they run some liquid through cooling channels? SpaceX going to build a smaller version of the NASA crawler?
With the RVAC engines being more efficient in vacuum wouldn't it be more efficient and effective to just use the 3 RVAC only or do they not have enough delta-v to put Starship into orbit at stage separation
The Rounded Corners are too Eliminate Corner cracking. That is why Aircraft Quit using Square Windows, planes crashed from cracks on square window corners….

Check most large circular saw blades. They too have slits with stop drilling.
The original failure mode for the demise of the DH Comet jet liner. Square windows
Why planes and modern ships have windows with rounded corners.
The technical term is "stress riser". Rounded corners, chamfered edges and such prevent the formation of cracks.
Favorited this one to bump it up the list. Thanks, and will try to include this in a future vid. - Das

Appreciate it 👍 - Das
Fully and heartily agree!
Yes a NSF narrated video and coffee. Great way to start the day
that closeup of Ship 34's nosecone is shocking. it looks so smooth in every regard, its crazy to think SpaceX made such progress in 3 years!
Thank you thank you thank you for the two audio tracks! My sci-fi futurism ASMR is back and I love you all. I also love that so many people enjoy the commentary. NSF is top of the heap becusae you keep trying new things and innovating.
Im so happy that there is an ambient track still available ..... defiantly my favorite way to watch these, the old school way !!!!
Thanks for offering narration on these lately!
I personally enjoy the camerawork insights. It highlights the bts work with literally the best practical examples ❤
Thanks! - Das
Rounded openings, helps hinder metal fatigue (cracking at openings)
Das "Is it gonna move? Well it's on a truck so I guess it will move" HAHA Love the commentaries!!!
Thanks again for doing the narration. Makes things clearer for me.
Das, I really enjoy your commentary, it provides a nice explanation of what we are seeing and what is going on, even the camera issues too lol.
Once again DAS Awesome!!!!! Thank you & NSF!
Thank you for the narration. The context you provide is very much appreciated!🎉🎉
Great video. Love listening to your thoughts out loud.
Thanks as always for the update NSF ❤

I faithfully sift thru dozens of rubbish comments just to find the occasional valuable nugget like this one. Thanks!
Even if it is just you blabbing on, it is greatly appreciated!
at 8m 26s we can see how big Starship is compared to a human; really great shot
It‘s much easier that way: 8:26
and we can click on the 8:26 and see exactly what you're thinking.
8:34 Petition for camel cam! Thanks NSF for these great dailies!
I like your narration.
More great words Das and pictures Jack & Mary
Great commentary Das

can confirm, i've never noticed it but now i can't unsee it 😂😂
THANK YOU
As a welder, a square internal 90 degree corner can crack much easier than a rounded corner. You have a starting point for the crack in the corner
A double wide Tardis 😂 SpaceX just needs to paint it blue, I guess SpaceX is now traveling through Space and time.

@10:25 the "tardis" is condensing unit for refrigerant system. this style is very common in VRF heat pump for space conditioning.
I went to the grocery store yesterday. Well, my fiancé did. I'm so glad.

That is two SPMT’s working in tandem.

The rounded corners on the inside of the launch pad are for extra strength.
The Das commentary always points out interesting things in the video, thanks NSF team .
Gen 2 starship is doing the best X-33 impression so far.
Thanks for getting Alan Partridge to do a guest commentary 😅

Regarding the siding of the parking garage - the shape looks a lot like the "SpaceX" name, with room for the swoosh off the X on the upper right.
pretty cool all i want is some inside imfo on the f5 date ?😀
To John: (at 7:30) Is it a bird? Is it a plane? No, it's just one more Starlink!
Inside Das’ head. A scary place to be 😂
Cladding on the garage has perfect size for a very large SPACE X letters.
Thanks for the journey into your mind, LOL. Thanks also for the great video

Maybe those to untitled nose cones are for like a ship 26 kind of vehicle? Maybe just maybe?
The things on the parking garage might be for wind abatement, or to keep debris out.
Great...another one
I'm wondering just how fun it would be to work at NSF??... as I am watching / listening to the sleeping pondering...😊
Deep Thoughts With Das
skirt stringers don't have holes anymore? when did that change?
team mobile OLM 👇🏻
Is it possible for spacex to install a parachute on the hot staging ring so they could reuse it?
I think they’ve already said it will be incorporated into the booster in the future, so no need to burn time and money working out a parachute system now.
When are they going to put landing legs on both starship and booster. They should just put them on now and stop just letting them drop in ocean so they can be examined and make a better inspection. Starship is going to need landing legs regardless.
How good would it be if one of the tile workers wrote "Hi mum" on a ships tile.
They are rounded to prevent stress points in the steel from causing cracks.
Whose other head would you use?
Good to hear your keeping the dust off your 🐫 😂.
I can't wait for the Version 2 Silver Bullets, just to watch people pull their hair out over S26's descendants. 🤣
Thanks for opening your mind too us. 😂
Rounded inside corners add strength where a crack could form.
In the close up of the ship engine bay, we can see another pipe running down the inside of the skirt, with a bend at the end, like a drainpipe. What is that?
Count the engines - that's how many.

Curved corners spread the load
What extra protection was added to Space Shuttle engines since they projected out back? Did they run some liquid through cooling channels?
SpaceX going to build a smaller version of the NASA crawler?
There was a body flap that extended past the main fuselage to protect the engines during reentry. - Das
rounded openings - think airplane ; early maybe electra or dc3. square windows = broken plane, stress cracks.
10:19 It's probably structural, similar to how planes have rounded windows to distribute stress
With the RVAC engines being more efficient in vacuum wouldn't it be more efficient and effective to just use the 3 RVAC only or do they not have enough delta-v to put Starship into orbit at stage separation
and at 11.01 great spmt video. Please forgive me for so many comments but since you lead the Space Industry Media....
The Rounded Corners are too Eliminate Corner cracking. That is why Aircraft Quit using Square Windows, planes crashed from cracks on square window corners….
I guess you don’t need to call it an OLM now as there’s no suborbital Launch mounts anymore. So just LM?
Lol can you imagine if the stream of consciousness lasted the whole video... 😂
No I cannot 😅 - Das
@@NASASpaceflight could tell you were trying real hard. I was laughing my butt off! 🤣
