What a spectacular performance.
SpaceX's Super Heavy Booster 20 has just completed its biggest test before Starship Flight 13.
It was such a massive success that even Elon Musk had to praise the flawless execution.
And here's the crazy part.
Just hours earlier, China successfully recovered one of its rocket boosters over the ocean for the very first time
using a never-before-seen cable net capture system.
So, which one deserves your attention the most?
Let's dive in.
Finally, the day the entire Starship community had been waiting for a very long time has arrived.
At around 9 a.m. Texas time on July 10th, all eyes at Starbase were on Booster 20.
The countdown began.
3, 2, 1, boom!
All 33 Raptor 3 engines erupted to life at the same instant.
In a split second, twin rivers of orange fire blasted through both sides of the flame trench
while thousands of tons of super cold liquid oxygen and methane turned into enormous white clouds
that completely swallowed the base of the booster.
If you were watching from the ground, you could barely even see the launch tower 1 anymore.
Just fire, smoke, and a deafening roar so powerful that people at Starbase said
they could actually feel the ground shaking beneath their feet.
But my favorite view came later, when SpaceX released the aerial footage.
From above, you finally get a real sense of just how insane this test actually was.
It was so impressive that even Elon Musk posted,
anyone can visit the Starship factory and launch site in Texas,
as it is right next to the public highway.
It is incredibly inspiring to see.
Although, don't take that too literally.
During launch operations, the area is closed off,
so you definitely won't be wandering around anywhere near the site.
Booster 20 stood perfectly still on the launch mount.
While underneath it, all 33 Raptor engines roared to life,
producing over 9,200 metric tons of thrust,
roughly equivalent to the full liftoff power of a fully-fueled Super Heavy.
To put that into perspective, that's enough force to hurl a 70-meter tall,
multi-thousand-ton vehicle straight into the sky
if Mechazilla's massive clamps weren't holding it firmly in place.
And here's the really crazy part.
SpaceX didn't just fire those engines for a few seconds.
They held all 33 Raptors at full power for roughly 24 seconds.
That might not sound long until you compare it to Booster 19,
the first version 3 Super Heavy,
which only managed about 14 seconds in its full 33-engine static fire.
Those extra 10 seconds mean dramatically more heat,
dramatically more vibration,
and dramatically more stress on every single component,
from the Raptor 3 engines and propellant plumbing
all the way down to the launch mount itself.
This wasn't just the longest static fire ever performed by a version 3 Super Heavy.
It was the strongest evidence yet that SpaceX has turned Booster 20
into a far more mature, battle-tested vehicle,
one that's ready to finish what Booster 19 started,
a clean, controlled splashdown in the Gulf.
Speaking of Booster 19, you'll probably remember just how cautious SpaceX was
with the very first version 3 Super Heavy.
Instead of rolling it out with all 33 Raptor 3 engines,
they started with just 10.
Those engines weren't there to qualify the Booster for flight.
They were there to qualify everything else.
The propellant system, the plumbing, the structure,
and even the brand new launch pad itself.
Then came the static fire.
And a few of those engines didn't perform exactly the way SpaceX wanted.
So what did they do?
Believe it or not, they pulled every single one of those 10 engines off the Booster.
Yep, all of them.
Then they installed an entirely different set of 33 flight-ready Raptors,
performed a full-duration static fire,
and eventually launched Booster 19 on Flight 12.
Now, here's the part I absolutely love.
SpaceX didn't throw those original engines away, not even close.
At least four of them, Raptor 57, 73, 87, and 91,
have now found a new home on Booster 20.
To me, that's SpaceX in its purest form.
They're not just trying to reuse rockets after launch.
They're already reusing hardware during development,
long before the rocket has ever left the ground.
But wait.
The story gets even more interesting.
Even before Booster 20 lit up the pad,
Starship fans were already debating one question.
Could this become the first Super Heavy
that doesn't have to roll back to Megabay after its static fire?
Sounds like an odd question.
But there was actually a pretty good reason behind it.
A lot of people noticed that Booster 20 looked far more complete
than Booster 19 ever did at this stage.
The Chinese along the vehicle had already been fully closed out.
The temporary wiring bundles that were clearly visible on Booster 19
were almost completely gone.
Then Ryan Hansen, one of the community's sharpest Starship trackers,
spotted something even more interesting.
The main wiring harness near the base of the booster
now appears to disconnect underneath the Chinese,
potentially allowing technicians to remove it right there on the launch pad.
And suddenly everyone started thinking,
wait a second, if Booster 20 is already this complete,
maybe SpaceX doesn't need to send it back to Megabay at all.
Honestly, I thought the same thing.
If Booster 20 could stay at Pad 2 after its static fire,
SpaceX would eliminate an entire rollout,
and an entire rollback.
That might not sound like much,
but when you're moving a stainless steel giant
that's nearly 70 meters tall,
cutting out just two transportation operations
could save days of preparation.
Less work, less time, more launches.
That's exactly the future SpaceX is trying to build.
But this time, it looks like the community
may have gotten a little ahead of itself.
Not long after the static fire wrapped up,
Starbase posted a brand new road closure notice.
The description was incredibly simple.
And if you've followed Starbase for any length of time,
you already know what that usually means.
Booster 20 is most likely heading back to Megabay 1
for its final inspections before returning to the pad for Flight 13.
And honestly, that isn't bad news at all.
After putting all 33 Raptor 3 engines
through the longest static fire ever performed
by a version 3 Super Heavy,
bringing the booster back for one final health check
is exactly what you'd expect.
Once those final inspections are complete,
the next big milestone will be stacking Ship 40
on top of Booster 20,
followed by the final launch preparations.
And based on the latest FAA NOTAMs,
which now include atmospheric re-entry
and splashdown warnings for Starship Flight 13's upper stage,
July 15th is looking more and more like the target launch date.

Trust me.
The most exciting part of this story is only just beginning.
But before we dive into Flight 13
and the major milestones SpaceX is about to attempt,
let's head over to China first.
Because what happened there could have a real impact
on the future competition in reusable rockets.
On July 10th,
just a few hours before SpaceX lit up Booster 20
for its record-breaking static fire,
China successfully launched its brand new Long March 10B
from the Wenchang Space Launch Site on Hainan Island.
The upper stage placed its payload into the planned orbit,
but that wasn't what everyone was watching.
About six minutes after stage separation,
the first stage booster flipped around,
performed a controlled descent,
and dropped straight into a giant cable net.
Stretched across the deck of the recovery vessel,
waiting out at sea.
No landing legs, no catch tower,
just a pair of hooks mounted to the booster,
a network of tensioned steel cables,
and a descent precise enough for both to meet
at exactly the right moment.
It's the first time in history
a rocket booster has been recovered
using a cable net capture system.
And remarkably, it's also the first successful recovery
of a heavy booster for this rocket family
on its very first flight.
Pretty impressive, right?
Well, yes.
But here's something many people don't know.
This isn't actually a concept that originated
with China's space program,
nor is it as unique as SpaceX's Meshazilla catch system.
A few months ago,
Professor Dokir Semenov reached out to our channel by email,
explaining that this cable-based recovery concept
was originally developed by his company.
Along with his message,
he shared a collection of 3D renderings and concept videos
showing an almost identical idea,
materials that had been publicly available online years
before China's recent demonstration.
So that naturally raises an interesting question.
Did Chinese engineers independently arrive
at the same solution?
Or were those publicly available concepts
part of the inspiration?
But if the similarities are more than just coincidence,
the speed at which this concept went from
old renderings to a real-world demonstration
would be nothing short of astonishing.
Yeah, China caught one booster.
Once.
But SpaceX has done it over a hundred times.
And at this point,
a Falcon 9 landing barely makes the news anymore.
It's just Tuesday.
The gap between we caught it
and we do this every week at scale
isn't something you can close
by borrowing someone else's concept.
That kind of reliability only comes from years of failures,
fixes, and doing it again.
You can copy an idea.
You can't copy the reps.
Now, speaking of rockets doing things for the first time,
let's talk about what SpaceX is about to attempt
with Flight 13.
Because one of the most important moments in this mission
sounds almost laughably simple.
They're going to light a single engine in space,
let it burn for a few seconds,
then shut it off.
That's it.
It sounds like turning on your gas stove
and flicking it back off.
But this is exactly what SpaceX couldn't do
on Flight 12 back in May.
And if they pull it off on Flight 13,
that single Raptor 3 igniting in the silence of deep space
could be one of the most important moments
in SpaceX's entire history.
On the road to the moon, and eventually, Mars,
Ship 40 will fly suborbital,
meaning it won't reach orbit.
It climbs high, builds speed,
re-enters, and splashes down in the Indian Ocean.
The whole trip takes about an hour.
But during a specific window called the coast phase,
where the ship is just drifting through space
with no engines firing,
like a ball at the peak of its arc,
SpaceX is going to try firing up a single sea-level Raptor 3,
hold the burn for a few seconds,
then cut it clean.
This is called an in-space engine relight.
And to understand why it's so hard,
you need to understand one key thing
about operating in space.
On the ground, gravity keeps your propellants settled.
Liquid methane and LOX sink to the bottom of the tank.
And the intake always has fluid to pull from.
In space, there is no bottom.
Propellants float freely.
What engineers call propellant slosh.
You have no idea if your intake is pulling liquid or a gas bubble.
The fix is an ullage burn,
firing small thrusters to create a brief acceleration,
pushing liquids toward the tank bottom
before the main engine lights.
Simple in concept, brutally complex in microgravity.
And Flight 13 needs to get it right
for the first time with Raptor 3.
Because once they can light a Raptor in space on demand,
everything else unlocks.
The de-orbit burn, re-entry,
the landing burn back at the tower.
Every single step of a real operational mission
starts from that one capability.
Flight 13 is where Raptor 3 has to prove it.
And that's everything for today.
Thanks for sticking around.
