Hi, everybody. Welcome back to the show.
My name is Will Walden. I'm your host, and today we're
going to be talking about Spacex's Starship, But not only
the flight and the landing and the explosion of IFT 7, but some
things that went on behind the scenes at SpaceX.
Some insiders have tipped me off to a few things that have
happened with Starship in the past.
Now, whether that's IFT one through IFT 7, I can't tell you
this because this person needs to be hidden.
They weren't supposed to tell anybody this, but they told me
this. So some of the things that have
happened to Starship during the flights that could have gone
horribly wrong, but luckily they didn't in these circumstances
for some of this stuff. So I have to be very vague here
because I'm kind of protecting somebody.
This is an insider that's telling me things that have gone
wrong with some Starships. OK, so you know, there's a
booster on Starship. There's a giant booster.
It's about 250 feet tall and the ship itself is about 150 ish
feet tall. So the whole thing is about 400
feet tall. The booster is the part of the
bottom, if you're not familiar, and the top part is called
Starship. So in between there there is
what's it called? There's a, there's a a, a, a
stage in between there too. And the stage in between there,
the it's so it's a hot staging. So when the booster in the top
stage separate this part kind of takes all the energy from the
top stage when it kicks off and it pushes it to the side and the
hot staging ring flies off into, you know, into the abyss.
But the booster would come back and land eventually in one of
these flights. But I can't tell you which one
this is for. I mean, this isn't the one that
actually landed. So I'll let you speculate all
you want. So there's a thing, and I'm
looking over here because this is where my information is here.
During the separation of the Starship from a Super Heavy
booster, unexpected harmonic vibrations developed in the
interstage connection points. So everything's moving around,
everything's shaking. It's a very violent place
between the booster and the ship at all times during the flight.
Now, the oscillations caused a three second delay in a clean
separation. So if you go back and you watch
some of this footage and I can't show you the footage, but if you
watch some of the footage, you'll see there might be a
little bit of a delay and they might not even show it on the
camera. I've looked through a lot of the
footage here and I couldn't find the exact time that they were
talking about, but there was a three second delay between the
clean separation, which forced the flight computer to adjust
the vehicle's trajectory just enough to compensate for the
altered flight path. So what this is telling us is
that all systems, even if they go awry, the systems that are in
place to fix these things, they're there and they work.
So that was number one of about, I think I have 5 things here.
Yeah, five things that they sent me.
And these are for past launches. And like I said before, I can't
tell you which one it is because you could might be able to track
it to who this person is. There's a methane header tank
pressure anomaly as well. Header tank maintaining pressure
for the Raptor engines. Methane supply experienced micro
fluctuations causing brief thrust instability.
Flight computer constantly adjusted the engine mixture
ratio to maintain stable combustion, reducing overall
efficiency by about 4% for this one flight so that again it
means that there wasn't an explosion.
Nothing blew up during this time during the methane head or tank
anomaly, but it did reduce overall efficiency by about 4%.
And that could be a big deal if you're sending cargo for
somebody else into orbit. And if that 4% keeps you away
from the orbit that you need to go to, or makes the Starship
itself actually push harder and maybe not get you to the orbit
that you need to get to, because that 4% is a huge deal. 4 out of
100 is a pretty big deal. It's not huge, but it's 4%
nonetheless. And there's been problems
throughout all of these flights with the heat shield of the
Starship. We've seen these things blow up,
we've seen them meltdown, we've seen them burn to a crisp.
There's been heat shield problems since day one with this
thing. And it's impossible to get this
absolutely perfect because mind you, this is about seven flights
in at this point. At the time of this video, it's
seven flights in, so seven flights of an experimental
rocket. And they're still figuring out
the heat shield tiles and it's OK.
It's still a still not a production vehicle yet.
So they're still learning and they're still working on the
heat Shields. Now, before I go any further
with this, I want to ask you if you're subscribed yet because
I've noticed when I look back at the stats that only like like
10% of you are subscribed to the show when you watch the video.
So that means about 90% of you just come for this one video.
So if you could do me a favor and click the like and the
subscribe button to help out the channel, I would really
appreciate it because not only do you get my content, but you
get content that's similar to this that will be in your feed.
So let's go on to the next with the heat shield.
So several tiles on the windward side of Starship showed
unexpected thermal gradient patterns during re entry, with
localized hotspots reaching 1800°C instead of around 1500
ish. While still within safety
margins. Requires the vehicle to adjust
its re entry angle by an additional .7°.
This could be a big deal in the future if SpaceX was going to
land these rockets. That .7° could mean that they
might not be able to land the rocket back at Star Base or back
at Kennedy Space Center because they're off target.
So that could be a big deal in the future when Spacex's
Starship is trying to land. Now .7° could also, depending on
where it is in the flight, could send it over land and over
people and over a scary place. If it does blow up.
If it does have a Rudd, a rapid unscheduled disassembly, and if
that's the case, it could shatter, could blow up, and it
could just spray the whole area with a molten steel.
Imagine that you're just hanging out with your friends in your
backyard and you see the bright lights in the sky.
That's cool, but it's all shards of super hot, super sharp steel.
That's kind of dangerous and I don't know which flight this is
for Remind, I'm reminding you this now, but that did happen in
a past flight of a Starship. Now let's go on to the grid fin
actuator desynchronization. Now I'm going to go tell you
this again, this is from an actual person that's very close
to Starship's production. Just want to let you know this
and one of the four grid fins on Super Heavy experienced A50
millisecond lag and that's doesn't seem to be a lot right,
But it's in its hydraulic response time creating a
asymmetric aerodynamic control during descent boosters.
Flight computer compensates by adjusting the remaining grid
fins positions more aggressively.
So that's one of the reasons why they have all those grid fins.
If one is a failure, then the other ones can take up the
slack. SpaceX thought of everything.
It's redundancy man. It was built like that on
purpose. Not only is it for the drag and
to maneuver the rocket and the the booster back end, but also
in case one fails, the other ones can pick up the slack.
They thought of everything. Now the last one we have here is
the communication array phase lock error.
High band, high bandwidth communication system experiences
intermittent phase lock errors due to unexpected ionization in
the plasma field around the vehicle during re entry.
So think of whatever starships were coming back in that were
molten hot. Reduces data transmission rates
to ground stations by about 60% for about 45 seconds and that's
through critical telemetry, Yeah.
Or though it says critical telemetry remains unaffected.
So 45 seconds of data transmission had was missing
during this flight. So it could be something where
they miss a really important piece of data if they want to
use this flight as a a building block for the next flights and
they would just not have that data for the next ones.
So those are five things that no one's ever published before and
no one's ever seen before. And the reason why I have these,
and I'll tell you this, the reason why I have these is
because I spent about a year down at Starbase and I know some
people that are down in that area.
That's all I got to say. That's all I'm going to say.
So I'd be very bland about everything.
I can't tell you everything that's happening, but I can tell
you, like, because of these things.
And it hasn't shown really in Spacex's Starship launches and
the reentries that any of this has made a huge impact on the
actual flights, other than maybe the heat shield.
That might have been a thing. Gridfin was fixed.
Methane tank, methane header tank, pressure anomaly, That
might have been a thing, but overall efficiency was down by
4%. It's a pretty big deal
eventually. But yeah, they might be able to,
you know, fix that up. So I don't know if they fix that
up or what flight that was for. They didn't tell me which flight
these were for, by the way, because they didn't want to be
tracked back. So let me know in the comments
