Q & A

What was significant about the SpaceX launch described in the transcript?

The SpaceX launch was significant because it involved the biggest rocket ever made, known as Starship. Although it did not reach space, it provided valuable data and telemetry for future improvements.

What was the main issue with the launch infrastructure during the Starship launch?

The main issue with the launch infrastructure was that the concrete underneath the engines broke under the force, causing substantial damage and leading to the creation of a large crater.

How did the local environment, specifically the water table, contribute to the problems at Boca Chica?

The water table at Boca Chica is very close to the surface, which complicates digging down for repairs. Additionally, the missing dirt and concrete from the launch were thrown into the air, causing environmental and equipment damage.

What happened to the rocket during the initial part of the launch?

During the initial part of the launch, the rocket experienced engine failures and debris from the launch, including dust, sand, and pulverized concrete, was kicked up by the engines and blown by the winds.

Why was the rocket's trajectory affected by the engine failures?

The engine failures affected the rocket's trajectory because each engine accounts for a significant portion of the total thrust. The loss of thrust impacted the vehicle's acceleration over the force of gravity, causing it to hit Max Q later and deviate from its planned flight path.

What aerodynamic instability did the rocket face during its flight?

The rocket faced aerodynamic instability due to the center of lift being in front of the center of mass, which would cause it to want to flip around without control. The engine gimbaling was necessary to keep the rocket pointing straight.

What was the outcome of the Starship's flight?

The Starship eventually lost control, pitched around, and began a descent back to Earth. It experienced a structural failure due to the aerodynamic stress and the uneven distribution of mass and fuel.

How did SpaceX identify the location of the vehicle when it broke up?

The location of the vehicle when it broke up was identified through the flash of the explosion, which was detected by the GOES-East geostationary weather satellite. The plume and debris cloud were also tracked by weather radar.

What challenges does SpaceX face in recovering the debris from the ocean floor?

The challenges include the depth of the water, which is around 150 feet, making it accessible only to technical divers and not to amateur scuba divers. Additionally, the hardware on the ocean floor may still be considered hazardous.

What is the next step for SpaceX in addressing the issues faced during the Starship launch?

The next step for SpaceX is to conduct a thorough analysis of the data collected during the launch and focus on improving the stage zero infrastructure, which experienced significant issues during the launch.

Transcripts

foreign

Scott Manley here yesterday is SpaceX

launched the biggest rocket ever it

didn't go to space but it did dig deeper

than most other Rockets do yeah we've

been anticipating the debut launch of

Starship for over a year and we knew

that once the countdown hit zero

excitement was guaranteed we just didn't

know exactly what part of that

excitement would take for reference this

is my authentic reaction to watching

this event yesterday

it's moving holy it's going

I did not expect that

so I had been at a pretty amazing event

for the last few days but it wasn't

spectacular in the same way that the

largest rocket ever exploding over the

Gulf of Mexico could be so while we as

observers on the sidelines got to take

in the launch ascent and eventual

breakup of this massive piece of work

the people actually working on it they

presumably came away with a metric crap

ton of telemetry and data that they can

hopefully analyze to make things better

next time and I think the first thing

that they're gonna need to have a look

at is stage zero so stage zero holds the

rocket vertical it fuels it in theory it

will ultimately catch it but in its

current form they have had issues with

the concrete underneath the engines

basically breaking under the force it's

common for launch systems to include

Flame diverters or water suppression

systems to protect the rocket and the

launch infrastructure but the thing is

if you are trying to build a rocket

which could say land on Mars and take

off from Mars you may not have that

option and SpaceX had been well

aspirationally trying to avoid doing

this

it did indeed turn out to be a mistake

this is one of the early photographs by

La Padre showing a fairly substantial

crater but this image from an aircraft

owner this really tells a story you can

see that on one side the reinforced

concrete has had the concrete Stripped

Away leaving the rebar behind you can

see there's water by the way already

come floating in there and this is a big

problem with Boca Chica the water table

is so close to the surface they can't

really dig down now they could start

building it up but then they would have

to work with the Army Corps of Engineers

and of course they've already built this

giant Tower this is a big problem all

that missing dirt and concrete that had

to go somewhere a lot of it was just

thrown up into the air look at the

debris coming out of the bottom of the

rocket during this initial part of the

launch a big component of that cloud is

dust and sand and pulverized concrete

being kicked up by those engines and it

blew with the winds over uh South Padre

Island and a bunch of people had you

gotta clean off their cars but the

bigger flying chunks damaged ground

equipment including the tank farm but

more importantly some of that stuff must

have hit the rocket the vehicle took off

missing engines right away so I think

the clock was actually kind of wrong

because it was supposed to start

ignition at T minus six seconds and then

t0 would be takeoff but it was more like

T minus two and then t plus 4 when I saw

first movement now a lot of people

initially saw it leaning over and as if

it was about to fall I think that is a

pad avoidance maneuver which makes total

sense if you've got that amount of

propellant in there you want it to make

sure that if something goes wrong it

doesn't fall back down now the next

thing to look at is their Telemetry in

the bottom left they actually show which

engines are active and if you look at

the outer ring of fixed booster engines

the two in that ring that have failed

are next to each other and that means

that it's much more likely they failed

due to a common cause say of a chunk of

concrete impacting both of them that

being said we begin to see Progressive

engine failures over the launch

sometimes by a quite visible flashes now

this one this particular failure

actually looks to be potentially more

interesting than the others because this

is actually sitting ahead of the engines

and it looks like it might be part of

the fairing that covers things like the

hydraulic power unit and the hydraulic

power unit is pretty important because

it generates pressure in the hydraulic

system that is used to drive the thrust

vectoring and other mechanical parts of

the rocket less relevant is the people

posting images from this section of the

flight showing the rocket looking a

little bent I think this is entirely due

to Rolling shutter on the camera that

they were using the vehicle is fine and

straight

the other thing I'm seeing is a lot of

very bright engine Flames that's

consistent with uh engine Rich exhaust I

think a bunch of these engines are

failing in some way and they're slowly

shutting down as these failures destroy

the internals you might think that

Starship with so many engines should be

able to handle the loss of an engine or

two with 33 engines each engine is like

three percent the total thrust and

that's you know not that bad especially

when you consider that the vehicle had

no payload it's not quite that simple

because what you're actually interested

in is the XS acceleration over the force

of gravity so each engine accounts for

more like nine percent of the

performance and this lack of thrust is

enough to affect the trajectory so the

vehicle first of all it hits Max Q later

than it was supposed to but also as it

hits this point in the atmosphere when

it's starting to generate a vapor trail

you'll notice that it's actually kind of

going slightly at an angle to the

airflow I believe the vehicle is too low

and it's trajectory and it's trying to

lift itself up to get back on its

planned flight plan or it might just be

having trouble controlling itself which

is a big problem because the rocket is

aerodynamically unstable with all those

aerodynamic devices on the front of the

rocket the center of lift is in front of

the center of mass and that means that

without control it would want to flip

around so it needs to have the engine

gimbaling to keep the rocket pointing

straight so I think it's around this

time that the vehicle is starting to

pitch around in a manner the engines

cannot control it and whether this is

because they've lost hydraulic pressure

or it's simply gone too far outside of

its angle of attack envelope uh yeah the

vehicle begins this pitch around and it

is worth mentioning that there is a

planned pitch maneuver during the

separation sequence that the presenters

talk about but that's not what this is

this is a loss of control and you'll see

the angle of attack display has actually

flipped through 180 degrees because the

vehicle is really just spinning around

do note that the view inside made the

interstate showing the engine shows that

the structure of the rocket is actually

in pretty good shape it hasn't bent and

since it's no longer able to accelerate

the vehicle more or less is sort of

cruising upwards towards its apex its

peak speed was about 2150 kilometers per

hour and it will hit out at an apex or

an apogee off about 39 kilometers which

is a long way below their plan's

separation altitude now the presenters

did talk about the stage separation

happening I don't think that was ever

commanded because a prerequisite for

stage separation is shutting down the

engines on the main stage so that they

are actually they're not pushing the

spacecraft together that doesn't happen

instead the vehicle begins to fall back

to Earth and as it's falling back it's

accelerating the atmosphere is getting

denser it's going to hit the second Max

Q event and at that point I think that

actually causes a structural failure in

the rocket so we do have confirmation

from the FAA the light termination

system was activated but I think the re

the vehicle was failing before that

point because first of all we have a

potential leak of a image showing a

camera on the Starship fin showing a

bent structure and just the physics of

the situation makes sense we've got most

most of the fuel is now remaining in the

Starship which hasn't burned any the

rest of the tanks are empty and

everything experiences aerodynamic drag

more or less the same so you've got this

sort of point where you've got most of

the mass concentrated and the vehicle is

going to be bending around this location

and that's roughly where the bend

appears to be in that leaked image so I

think Starship makes this one final

rotation Edge on into the Airstream it's

at 31 kilometers now it's fast again and

the booster tanks fail and then Starship

has its flight termination system

activated and then debris rains down

over the Gulf of Mexico the camera views

do show the uh solution starts down at

the base of the rocket which could

actually be a flight termination system

activation but it does appear to show

that it is slightly not straight anymore

again really hard to see uh and I'm sure

SpaceX have the data and I'm sure

they're excited to look over this data

and maybe get to fixing some of the

problems but yeah it does look like

stage zero is going to be the main focus

of attention

we can actually figure out roughly where

the vehicle was when it broke up thanks

to the flash of the explosion which

showed up on the lightning detector

offer goes east which is a geostationary

weather satellite this also picked out

the plume on ascent and the shadow that

it cast in the early morning sun the

plume and the debris Cloud that was

generated also showed up on a weather

radar and of course all this actually

helps us potentially locate where the

debris might actually end up so the

light stuff will tend to fall straight

down the heavier stuff will continue

further out to sea so if we overlay the

weather data with a marine map we see

that the water there is about 150 feet

deep so basically don't try going there

if you're an amateur scuba diver this is

well in the range of technical diving it

is possible but the experts only and

remember just because that piece of

Hardware is on the ocean floor doesn't

mean that it's not itar

so yeah to everyone at SpaceX that

worked on this I I hope you're feeling

good because you get a lot of work to do

I can't tell you when the next launch is

going to be while they have got boosters

and Starships lined up for tests two and

three it's very clear that stage zero is

gonna need some serious civil

engineering to solve the problems I'm

Scott Manley fly safe
