1
Starship has delivered another spectacular performance as Flight 13 is now in the history books.
2
The booster completed most of its objectives and the ship performed flawlessly.
3
We're going to give you a full rundown of exactly what happened
4
and even take a quick look into the not-so-distant future at Starship's 14th flight as
5
that may be closer than some might think.
6
As always, we have all that coming up and more on this week's Starship Update.
7
Let's get right into business and the countdown here.
8
After a small hold around the T-57 minute marker,
9
Starship proceeded smoothly through propellant loading and right through the gate at T-60 seconds without any additional holds being called out.
10
As the count came down to ignition, everybody was watching very closely.
11
This is the point on the first attempt
12
when Booster 20 ignited some of its engines before aborting at the last possible moment due to four Raptors failing to ignite.
13
And we now know what caused the abort, specifically why those four Raptors failed to ignite.
14
According to SpaceX, the issue stemmed from the oxygen turbo pumps on those four engines.
15
Two additional engines had the same problem, but still managed to ignite.
16
The turbo pumps are what feed propellants into the engine, one dedicated for liquid methane and the other for liquid oxygen.
17
But thankfully, these four never ignited though.
18
Otherwise, it would have been a very fuel-rich event, since the methane side was operating just fine.
19
We also learned that Starship will only tolerate a maximum of two engines out before calling an abort on the pad.
20
For version 1 and 2 boosters, that number was 3.
21
So it's quite interesting to see how that's changed.
22
Before restacking for the next attempt, Booster 20 ran a quick verification test on pad 2 with its six new engines,
23
having those installed and swapped out for the faulty units in Mega Bay 1.
24
It was essentially a sort of half spin prime.
25
They spun up just the oxygen pumps on those engines as a sort of leak check.
26
Because no methane was involved, though, they did not need the Detonation Suppression System, or the DSS.
27
After SpaceX replaced six engines on Booster 20, conferring during their third attempt's stream, and rolled both vehicles out for stacking,
28
Flight 13 was initially targeting Thursday, July 23rd.
29
But that didn't last very long, though, as Thursday's attempt was called off fairly early due to poor weather conditions.
30
Rather interestingly, one of the launch commit criteria this time around was being able to see the rocket from ground cameras
31
so SpaceX could observe the heat shield through Max-Q.
32
With heavy cloud cover, that just wasn't possible.
33
But while we're on the subject of weather, SpaceX revealed something pretty interesting during the third attempt stream.
34
Starship is allowed to launch through lightning.
35
This comes after a Chinese Long March 3B rocket was struck by lightning on ascent and still completed its mission successfully.
36
The fact that Starship is capable of flying through lightning seems like a relatively new development.
37
Previous flights, like Flight 10, were scrubbed for anvil clouds and storm activity in the area, which we're actually kind of used to in Florida operations, but obviously this is not Florida.
38
It's pretty strange to say this out loud, but lightning no longer seems to be a major concern.
39
I mean, as long as the winds cooperate, we could realistically see a Starship launch through pretty adverse weather, which is pretty important if SpaceX wants to meet their higher launch cadences,
40
as weather will not always be perfect, especially in Florida.
41
Now back to the countdown.
42
The deluge kicks in around T minus 10 seconds.
43
All engines ignite simultaneously and Starship is released from pad two into the South Texas sky.
44
After it punched through Max-Q, SpaceX gave us some stunning first-time views from the booster's engine bay, showing the Raptors firing in unison.
45
I mean, how wild is it to be seeing both frost and glow from heat existing in such close proximity here?
46
Like, that's just Raptor 3 in a nutshell for you.
47
Next up was hot staging.
48
Booster 20 shut down 28 of its 33 engines, leaving 5 still burning.
49
Ship 40 then ignited its six engines in a staggered sequence, separating both vehicles.
50
The ship continued toward orbit, while the booster, for the first time with a version 3 variant,
51
successfully flipped straight upward as intended and relit all 33 engines for the boostback burn.
52
The boostback looked mostly clean, but it ended a few seconds early.
53
According to SpaceX's timeline, it was supposed to last 38 seconds, but only lasted for 26.
54
The website later confirmed the early cutoff, though they didn't exactly share why.
55
Unlike Booster 19 on Flight 12, Booster 20 did manage to light most of its engines for the landing burn.
56
It started with 10 out of 13, then dropped to 8, and then an off nominal 5 before hitting the water pretty hard.
57
Albeit not as hard as Booster 19, because that was basically supersonic.
58
Unfortunately, that landing burn failure means we probably won't see a booster catch on Flight 14.
59
But it does not rule out a catch entirely, but more on that later.
60
Additionally, no successful booster catch on that flight means Starship's arrival to Florida could slip even further, unfortunately.
61
Reusing a booster even once would give SpaceX some buffer in production, allowing them to send one to the Cape while continuing launches from Starbase with other units.
62
Without that, the Florida timeline will likely get pushed deeper into the production queue.
63
Hopefully, if Booster 21 lands as intended, then Booster 22 could be caught and either reused in Florida or make room for Booster 23 on the Space Coast.
64
Now let's talk about ship.
65
On the last flight, Ship 39 made it to Seaco, but about 40 seconds into its descent burn, one of the Raptor vacuum engines shut down unexpectedly.
66
While that demonstrated engine out capability and still allowed for the ship to maintain its targeted trajectory, it meant that other in-fund objectives, like the in-space relight of a Raptor, had to be called off.
67
Ship 40, by contrast, performed brilliantly.
68
All engines stayed lit, and it maintained its targeted trajectory as planned, allowing the rest of the mission to proceed.
69
Something new happened at engine shutdown, though.
70
Unlike previous flights that reached this point, the vacuum and sea-level Raptors were all essentially cut at the same time.
71
Not even a quarter second apart, even.
72
On earlier flights, RVACs were always shut down several seconds before the sea-level engines, mainly for trajectory precision.
73
Running every engine for the full duration is almost certainly for the same reason
74
that they now light all 33 engines on booster for its boost back.
75
It's simply more efficient.
76
If you can run more engines for a longer period of time, then you have more power to fight against gravity.
77
All of this is ultimately aimed at increasing Starship's full payload capacity.
78
While a ton of that work comes from physical design upgrades, a big part of the challenge is also optimizing the software and current hardware behavior.
79
When the time came, Ship 40 oriented the Pez dispenser facing pro-grade, or the direction facing the vehicle is traveling, and successfully deployed all 20 Starlink version 3 satellites.
80
We know six of those carried cameras to image the heat shield, but we have yet to see any footage from them just yet.
81
We're hoping SpaceX was successful with that and released its set footage soon.
82
And honestly, I really have to hand it to SpaceX here.
83
The views on this flight were incredible.
84
And if you would like a third person view of Starship on your wall, check out our high quality Flight 13 metal prints,
85
plus some celebratory merch, all available at shop.nastaspaceflight.com.
86
We are incredibly proud of these, and we certainly hope you enjoy them.
87
Because the ascent burn for ship was nominal, SpaceX was able to complete the in-space relight objective.
88
This successful short burn gives Starship the best chance yet of reaching orbit and an on-site recovery very soon.
89
We even have confirmation from Elon.
90
Unless problems show up in the flight data, SpaceX will attempt a ship catch on flight 14.
91
That's exciting.
92
We've already seen three boosters caught so far.
93
Pulling off a version 3 ship catch before a version 3
94
booster catch would really highlight how far things have come since the version 2 era.
95
Back then, at least early on, ship really struggled hard and had failed on its first three flights overall.
96
And finally, we come to the last phases of flight.
97
Re-entry, the belly flop, and landing.
98
Ship 40 powered through peak heating and then began the return to launch site phase.
99
Once again demonstrating excellent cross-range and control capability as it aimed for the splashdown area.
100
And also the plasma on the cameras overall is just wickedly cool.
101
Like that never gets old, genuinely.
102
Shift 40 then simulated an alignment maneuver towards the tower with what was one of the fastest like pseudo-flatspans I've ever seen, especially for a vehicle of that size.
103
After one hour and five minutes, Shift then lit its sea level engines one last time, flipped engines down, stepped down to two engines,
104
then one, and landed softly in the waves of the Indian Ocean.
105
Talk about picture perfect here, But here's the real cherry on top.
106
Unlike every previous Starship Splashdown, Ship 40 did not explode when it tipped back over onto its side in the water.
107
Even better, as in T-Plus 12 hours, the vehicle was still floating and still transmitting data, despite antennas being literally underwater.
108
Plus, our friend Harry Stranger was able to task this satellite imagery, showing Ship 40 floating alongside support vessel Ghostralis 56 hours after Splashdown.
109
I guess we can finally say Ship 40 put the ship into Starship.
110
Okay, never mind.
111
Bad joke.
112
Moving on.
113
The batteries are designed to last around 48 hours.
114
And they'd have to, because that's about how long Starship is capable of staying in orbit before having to re-enter and land.
115
We still don't know what is yet to come for Ship 40.
116
SpaceX has tried to recover ships intact before, and failed when they exploded.
117
It seems they had largely given up on hopes of recovering one after flight.
118
But clearly they were not prepared for it to actually survive this time, because there it is, and look at how glorious it looks.
119
Fingers crossed they managed to think up a plan for at
120
least bringing parts of Ship 40 back to Starbase for very thorough analysis.
121
And maybe even for display.
122
I mean, there is a brand new rocket garden hopefully going up right over there.
123
Flight 13 was certainly a great step forward, and one of the more memorable missions as of late.
124
But it's going to get even more exciting real soon.
125
I mean, while on the Space Coast, someone seems to have missed a memo about which pad Flight 13 was launching from,
126
as the Starship tank farm at launch Complex 39A spooled up for testing big time.
127
All jokes aside though, we are getting closer and closer to Starship's long-awaited debut from this very launch pad.
128
It's only a matter of time before the first vehicles make their way over, hopefully in the next couple of months.
129
Over at launch Complex 39A, besides the aforementioned tank farm testing, work has been mainly ongoing on the booster quick disconnects.
130
SpaceX attached the middle section of the methane BQD hood before
131
removing it to allow workers to access this area again and then reinstalled it again.
132
The tower chopsticks have also been on the move, this time with some very large vertical travel for the very first time.
133
They were raised slightly back in late June, likely just a functional test.
134
But these latest movements are significantly larger, and it's about time too.
135
Those chopsticks have been sitting on that tower for more than three years.
136
As we've covered before, Pad 39A will support the very first Starship launches from Florida.
137
It's encouraging to see more of the site coming online and being properly tested, from the tank farm all the way up to the chopsticks.
138
At Space Launch Complex 37, the first of two launch towers has finally risen to its full height with the stacking of the ninth
139
and final tower module.
140
Seriously, I mean, I come to Starbase for two weeks and suddenly another tower is fully stacked in Florida.
141
I mean, good grief.
142
Even so, the site is still some time away from supporting its very first launch.
143
There is a huge amount of work left inside the tower, plus digging and building the flame trench, plus the tank farm, and ASU, and so on.
144
Although some hardware is already on site for those, so stay tuned.
145
Coming back over to Starbase, SpaceX is already full steam ahead in preparing for the next flight, and for more in the future in the Megabase and in Star Factory.
146
Both Flight 14 vehicles are already well into their testing campaigns.
147
Booster 21 just completed cryogenic proof testing at Massey's, where it was loaded with liquid nitrogen and liquid oxygen to verify structural integrity.
148
Meanwhile, Ship 41 has begun to receive its six engines ahead of static fire testing.
149
Once again with version 3, the boosters appear to be lagging behind ships in production and testing.
150
And we can thank Booster 18 for that pattern.
151
But still, it shouldn't delay Flight 14 too significantly.
152
Booster 21 isn't the only possible bottleneck, though.
153
If Flight 14 is truly going to orbit, SpaceX will also need some license modifications from the FAA.
154
They're not major, but they matter.
155
Right now, the license allows the ship to re-enter from orbit, but it only permits landing in the Indian Ocean, not at Starbase.
156
Currently, the only vehicle authorized to land at the launch site is a booster.
157
So that obviously needs some adjustments.
158
Let us know in the comments what you think the path to Flight 14 looks like from here, and when you expect it to launch.
159
So what would Flight 14 actually do if it reaches orbit?
160
It's a great question.
161
First, the booster would almost certainly need to demonstrate a soft landing in the Gulf before attempting a tower catch.
162
The risk is still too high otherwise.
163
So we can likely roll out a booster catch for this time.
164
The ship would aim to deploy version 3 Starlink satellites once again, but into orbit for the very first time.
165
These probably wouldn't join the operational constellation right away, but they would give SpaceX a lot of valuable on-orbit testing data.
166
I mean, they did great last time, so hopefully more of the same this time.
167
Ship 41 may then go to demonstrate staying in orbit for a long-ish period of time, a maximum of 48 hours according to SpaceX.
168
It will then de-orbit by igniting a single sea level engine
169
for what will hopefully be the first re-entry over to Starbase and the first catch of a ship at Tower 2.
170
The production of even later flight vehicles is also proceeding nicely, as just before Flight 13, the aft section for Ship 42 was moved into Mega Bay 2,
171
meaning that ship is now fully stacked.
172
And into Mega Bay 1, SpaceX moved the methane landing tank and the booster's final aft section before the engine bay.
173
Now, just after Flight 13, SpaceX rolled Booster 22's Falcon 9-sized transfer tube into Mega Bay 1,
174
and won a Ship 42's aft flaps and both raceways into Mega Bay 2 for attaching to the ship.
175
It shouldn't be too long now before Ship 42 is ready for crowd testing at Massey's, and hopefully, Booster 22 isn't too far behind either.
176
As we all know, Starbase never sleeps, so the progress will always continue.
177
Starship Flight 13 was certainly a great one, but it will surely pale in comparison to what lies ahead.
178
Looking towards Flight 14 and onwards, go ahead and tell us, what will SpaceX actually perform on Flight 14?
179
Booster catch despite the issues?
180
Or actually push for a ship catch?
181
There's only one way to find out.
182
Let us all know in the comment section down below.
183
I'm Max Evans for NSF, thank you so much for watching, and I'll catch y'all next time.

シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
