Episode Transcript

(00:00):
Just a few weeks ago, on August 26th, engineers oversaw the 10th
full scale test of Spacex's Starship stack system using the
Super Heavy booster and Starshipupper stage.
This launch originated from Starbase, Texas, just north of
the Mexican border off Hwy. 4. SpaceX aim to resolve propulsion
and propellant handling issues that had Hanford previous

(00:22):
flights. Things blew up, and the team
also wanted robust data on Starship's heat shield, which is
a fast matrix of thousands of tiles.
The shield. The vehicle.
Stainless steel hall during the searing reentry phase.

(00:43):
Think about this. This flight's outcome was a
major technical win. Starship lifted off, completed
staging and guided itself more than an hour later to a
controlled splashdown in the Indian Ocean.
It's huge. They were northwest of
Australia. The vehicle missed its bullseye
splashdown target by just three meters, which is pretty close,

(01:04):
but not close enough to catch iton the arms.
There was a buoy there that caught the footage, and it was
absolutely beautiful. But Starship belly flopped into
this and then lighting three of its six Raptor engines that
flipped upright before settling into the oceans.
Now there was clear evidence of post flight thermal and
structural wear though, with scars visible on Starship's rear

(01:27):
and control flaps. Any distinctive rusty orange
streak right down the middle. It was huge.
You can see it. It looked like the SLS rocket,
but Elon Musk identified the orange coloration as oxidation.
No big deal. Starship carried experimental
metallic heat shield tiles for this flight.
The company wanted to compare their durability with the more
traditional ceramic tiles, and unlike previous test flights,

(01:52):
nearly every tile, regardless ofits type, survived the entire
mission. Engineers deliberately affixed
just three metal tiles to 1 area, hoping they would simplify
the heat Shields construction and also the maintenance of it.
Replacing those other tiles is apain.
It takes days. The result though?
The metallic tiles oxidized fiercely in the high oxygen

(02:14):
atmosphere. It did not effectively insulate
against heat. The dramatic color of orange
echoed the old external fuel tanks of the space shuttle SLS
as well. So this is a technology that
NASA tested decades ago but never took operational.
You can drill further down into this, too.

(02:35):
While the metal tile test failed, it delivered valuable
lessons for SpaceX engineers. They discovered substantial
heating and also erosion wherever gaps between tiles were
the largest, and sometimes heat migrated between the tiles and a
bladed a backup thermal barrier underneath them.

(02:57):
Scary. It's similar to the white
ablation layers used on Spacex'sDragon capsules.
Small areas near Starship's nosewere also left deliberately
exposed to examine direct heating effects.
This led to white blotches wherethe underlying material ablated.

A robust, rapidly reusable heat shield remains Spacex's biggest

(04:03):
unsolved engineering problem forStarship.
The structure must handle violent launch vibrations,
extreme heating, temperatures cycling and also sudden
deceleration forces as the rocket returns to Earth and
perhaps is caught by giant ground based arms.
Star based Texas for immediate relaunch.

(04:25):
Now. The classic ceramic tiles on
NASA's shuttles demanded hand inspection and repair.
People had to go check them out.This undermined rapid reuse.
It took days sometimes. SpaceX envisions A Starship that
can launch, land and fly again in one day.
That'll remain out of reach until heat shield ceiling is
reliable and also robust. SpaceX has a long way to go now.

(04:50):
Spacex's solution, though, centers on a new material
engineers called Crunchwrap. Technicians wrap each ceramic
tile the kind of thermal gasket,before attaching it to Starship,
using robots to snap the tiles into place.
The Crunchwrap fills spaces between tiles, preventing heat
from poking through places once crammed with complicated gap

(05:12):
fillers on the shuttles. Gap fillers sometimes escape
their slots mid flight, creatingrisk, and SpaceX wants to avoid
this. The upcoming 11th test flight
will see the entire shield wrapped in this new material.
Crucial experiment to validate tile sealing on operational
Starships. Flight 11 will repeat the now

(05:32):
familiar suborbital arc, keepingmost mission variables constant
to create a strong baseline for analyzing the new heat shield
design and the Crunchwrap. The team will avoid introducing
too many design changes at once and focus instead on preparing
for next year's pivotal upgrades.
Now in preparation, engineers static fire test the assigned

(05:55):
the Super Heavy booster, which had already been recovered using
catch arms in a prior flight to guarantee reliability and
beyond. Flight 11 though version 3 of
both Starship and Super Heavy. They are the next watershed for
the program. These Block 3 vehicles will
first fly in suborbital tests and these validated systems.

(06:16):
SpaceX will send one in orbit targeting the 13th mission or
soon after. For the first complete circuit
of Earth. This is huge.
Achieving orbit will lay the groundwork for in space
demonstrations such as large scale propellant transfer and
also the much anticipated attempt to catch and reuse A

(06:37):
Starship after it's been all theway around our planet.
Now, the jump from suborbital toorbital missions is significant.
Every test so far has brought Starship back to Earth before it
circled the globe, allowing SpaceX to maintain precise
control over debris and the recovery process.
To send Starship into orbit and bring it back, the team must

(06:58):
guarantee the ability to land Starship exactly where it wants.
A prerequisite for safe, reusable missions involving both
uncrewed satellites and also human crews and orbital Starship
will unlock a host of new engineering challenges and
mission possibilities. The ship can begin deploying

(07:19):
larger batches of next generation Starlink satellites,
which supports Spacex's growing communications empire.
Most importantly, orbital missions will make propellant
transfer in space possible. So this is absolutely necessary
for flights to the Moon and to Mars because a fully fueled

(07:41):
Starship can't lift off from Earth with enough propellant for
the outbound journey and landingon Mars.
Major efforts in 2026 will focuson this new technology, the
crucial step for leaving Earth orbit.

Thank you so much. Flight 10 also delivered key
lessons from Super Heavy's own control splashdown.

(08:26):
Engineers deliberately sent the booster back for a water landing
in the Gulf of Mexico rather than attempting an on pad catch
again. This exposed the rocket to
greater aerodynamics and structural stress on descent,
allowing the team to see just how well the booster could steer
itself during the final approachphase.

(08:48):
The observed aerodynamic behavior during descent did not
match Spacex's computational models or even wind tunnel data.
The booster showed greater stability in actual flight than
in simulations, which even surprised SpaceX as senior
engineers. And SpaceX invited outside
researchers at universities and government agencies to help

(09:10):
investigate these discrepancies.While SpaceX moves rapidly once
it finds a solution that works, broader understanding of why the
booster behaves more stably in real life could lead to even
better control systems and saferfuture missions for Starship.
In the future, the rapid engineering cycle on Starship
typifies Spacex's philosophy. Test new ideas directly and

(09:34):
frequently, iterate based on hard data and replace or improve
anything that falls short. Just two weeks after Flight 10,
the company not only knows wherethe heat shield failed, but it
also has a fix in a hand and ready for the pad.
The Crunchwrap test in Flight 11will determine if this approach
brings the dream of daily reusability and or world class

(09:58):
rockets closer to reality. If it works, Starship could
finally fulfill its greatest promises, not only for SpaceX on
Mars, but for NASA's lunar landing plans and a new era of
reusable Space Flight.
