- In this episode of NSF Live, Das talks with Dr. Phil Metzger, who recently published a paper about the particle interaction during the Starship Flight 1 pad destruction. This show will dive into how this paper came to be, the lessons learned from Flight 1, and how the mishap during the first Starship flight occurred.

Wow, was I ever surprised how great this interview was!
Thank you Dr Phil and Das! Happy Easter!
Great interview, I went into this half hearted thinking it would be to dry of a topic… nope I was wrong… I listened the full duration and learned a lot. Thanks so much!
It certainly wasn't dry, there was a lot of water talk
Thanks Das and Dr Phil, great interview.
So proud of Maj. Brandon Dotson, an incredible paper and really great commentary here.
Man, y'all's intro! It still gets me so hyped every time!
I just finished watching it! Congratulations on the great interview, Dr. Metzger! I can only dream being so calm, composed and elaborate as you (and Becky) when explaining science, for which I often get "reminded" by my colleagues. On the topic, I think your investigative work actually did a great contribution to science and future spaceflight, even if we all joked about the Starship fiasco at the time. Das, you we're as always an amazing host.
I was at Isla Blanca for the launch and drove to Brownsville after for food and people were talking about it. I didn't know and thought they were crazy, it's wild how this all tied together
There was dust on our car windows in Colorado after the Mt. St. Hellens eruption in Washington in 1980. That’s about 1300 miles.
I assume that’s because the dust got into the upper atmosphere and the wind carried it here.
In the UK we get sand from the Sahara coating everything from time to time. That's between 1500 and 2200 miles depending on how it's measured. It's nuts.
Congratulations to all participants becoming published authors ... For scientific preprint. It's great to see some open review commentary online.
I am surprised Grady didn't get on it
Great video! And great job, Das! We miss you on the weekly updates and launches. You appear to have listened well to your wife and studied up on the technical aspects of the testing. Points, baby.
Thank you very much for this super informative and passionate conversation!
You're welcome, thanks for watching!
@@NASASpaceflightit’s truly our pleasure to watch such informative content. And I hope the medical info has been simplified and released to the concerned public
Really? Chit chat about an old launch?? WOW was my initial thought wrong. This was an amazing analysis and I learned so much. So much information, thanks for breaking it down 🤣!
Proper science takes time! 😅 - Das
Wow!! Extremely interesting. Dr. Phil Metzger deserves a medal. 💫 I think a huge hurdle has just been jumped.
Great story and explanation of the time line of events . . . and the detective story behind it
Raptor-side Chats are awesome!!
Awesome, Informational, show! Thanks Phil and Das
This was a very interesting analysis. I also downloaded the paper and read it. The paper states "It is possible that thermal convection also drove rotational motion inside the cloud that kept the debris suspended...". This undoubtedly is true but is unlikely to be the primary cause of the lofting of the particles. It is commonly believed that clouds are formed due to thermal motion, but this isn't actually true. Clouds form because water vapor is lighter than air. Surface water vapor will rise in the atmosphere (independent of temperature) until it reaches the Lifting Condensation Level (LCL) where the water condenses. It is my belief that once the subsurface water was turned to vapor it simply floated upward carrying particles with it until it reached the LCL level in the atmosphere.
Thanks for the comment Tom! After this conversation, we pulled all our extended footage of the cloud and will make it available for research and review. - Das
The explosion is very much like a hydrothermal explosion or phreatic eruption in volcanoes. The magma heats the water which eventually flashes to steam causing a huge explosion which results in a big crater without lava getting on to the surface.
Thank you both
Great interview! From the moment Phil mentioned the build up of pressure because of water under pad, my thoughts were going to pipes underneath allowing steam to escape of side... I guess something like that is the way of the vented pad mentioned at the end.
So glad i listened to this. Very interesting and in a previous life I was involved in infrared spectroscopy (FTIR). 🤖🚀
They should redo the intro and add the starship footage in space
NSF only uses NSF footage
This was fascinating - thank you so much!
Fascinating indeed!
Great episode!
nice interview
Amazing!
Concrete holds water itself. One places sand on the foundry floor because as soon as the 1250’C bronze hits the cement it explodes. Ejecting the bronze back towards you. The heat creates a lot of vapour as the water 💦 is drawn to the bronze heat&the interaction of water via steam exploded water/cement. The sands/which is basically far more silicate orientated and it really basically turns that sand in to glass globules. In fact they often glaze the bronze and glazes it and prevents air effecting the bronze surface from disintegrating from the air as it usually would do. It’s by no means the same thing. But a ver common foundry happening. It’s basically a heat into cement occurrence. We used that foundry casting cement area for 7 years. With the same results. It was an indoor foundry and never washed down etc. I expected this response in fact. In fact these. There are also material s like that which the metal bar is made up of. IE. U get bronze 90% copper and 10%tin= PB1. Copper Tin&lead. PB2. The lead eats our lungs 🫁 and is negative to humans. The same occurs since we understand the materials. Metal has rust(or oxide&it is responsive as are all other materials. Anyway leave it on the launch pad. Including fuels coming off after burns.
Fascinating!
Rapid Prototyping always leverages lessons learned from prior efforts. I not sure the SpaceX engineering team fully embraced this. Examples - Pad design for Saturn V, Launch stool for Taurus ELV, launch of Atlas E and Titan II out of silos.
Curious! Can you post a link to the “50 ways” paper? Wondering if establishing a magnetic field around the launch “pad” would capture any ejected regolith?
an hour and a half about sand. cool.
U need to put heated metal rods below to dry your lower soil. Then introduce colloidal silica and regolith. Liquid poured and allowed to dry from below. Then heat actually Sets the colloid silicates the size of the required pad. But I’d say it’s roughly a good approach to attempt. It’s chances are high. Moon landing source. Ric.Chamen. Receipy available.
So, the “hole” beneath the pad became a barrel after enough erosion/breakage of the reinforced concrete and buildup of gas beneath the mixture of sand/water/broken up concrete?
shapes of your pavers should look more like shakes on a roof, with that little spike in the center, and each ring of pavers directs exhaust gas out over the next ring, each ring starts underneath the inner.
Would be great to have some timelines
Excelent
What landing had a hover regicide that lowered the lander? This was elevated thrusters.
Huh?
Starship cloud seeding!
So every starship launch with a South East wind will increase probability of rain in the area north west. #terraformthedesert
I would imagine changing some variables doesn't tell you about other changes. That entire space program is startling.
Any engineer would tell you last launch had broken attitude control, perhaps stuck activated one of the many rockets. Frustrating to watch
The very last thing I care about is hearing about this again. I suppose I could have just noted the not interested option in this video. 🙄 Doh!
Interesting... you had already read the paper that corrected a bunch of original speculation and incorrect information about the pad failure mode? There were quite a few videos about it, which this analysis calls into question. - Das
@@NASASpaceflight Then I stand corrected, although I'm sitting right now so I sit corrected. Thanks for the response. That was a presumptuous comment on my part.
No problem, I know a lot of folks thought it was settled with all the speculation... which I why I thought this paper was so interesting (and worthy of a show) Cheers! -Das
Totally off point, why is Das’ face so red?
The redness is obviously due to excessive sun exposure on someone who has skin that has evolved over time to survive in a bog.
Christ is risen.
This is really old info. What’s the point
Given the paper was released a couple of weeks ago, it ain't old info
feels like phillip is having a "get off my lawn" moment....@@ale131296
DAS.... dude your such a fricken hard ass! like somehow balancing what your doing whiten 😂that whiten bullshit constraints...
