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

thank you
