All language subtitles for 02-What Exactly Happened on 2nd Launch

after 212 days of repairs upgrades and

iteration SpaceX just attempted the

second integrated Test Flight of the

Starship launch vehicle and the

improvements were obvious the last

flight was on April 20th earlier this

year and ended with a bang after a few

issues with the Launchpad engines

internal fires Etc this time around we

saw a very different result from engine

ignition all the way to an eventual

explosion with this test complete SpaceX

now was a lot of work ahead of them as

they find out exactly what went wrong

and launched the next Starship prototype

here I'll go more in depth into what

happened on the the second flight test

where the issues arose what to expect in

the near future and
Second Launch Attempt

more with just 1 minute left until

launch and the sunrise in the background

all the Raptor engines were chilled the

rocket was filled with around 10 million

PBS of propellant and it prepared to

start up its engines as the clock hit

T-minus 40 seconds there was a plant

hold for a few minutes as teams checked

each system along with ensuring no

civilian Boats were within the

restricted launch area despite space

having around 15 minutes of time to hold

it only took around 2 minutes before the

clock resumed counting down as the clock

hit close to tus 5 Seconds the water

cooled steel plate began shooting out

water in preparation for liftoff then

right at T minus 0 all 33 Raptor engines

ignited and began blasting the pad only

around 4 seconds later and Starship was

in the air by t+ 10 seconds it had

cleared the pad entirely this was much

faster than the first intergrated test

flight which was by Design soon after

the vehicle began accelerating with all

33 Raptor engines working prop ly as

indicated by the flight data provided at

the bottom at t plus 42 seconds SpaceX

switched camera angles which gave a

great view of the bottom of the booster

here you could see that all 33 Raptor

engines were still working without a

single engine missing it's important to

point out that on the last Starship

integrated test flight by around 40

seconds in there were already multiple

engines missing by t+ 1 minute and 12

seconds they called out that Starship

had reached Max Q which is the moment a

peak mechanical stress on the rocket at

that point Starship was traveling

around, 1500 km an hour and close to 15

km High these numbers continue to

increase over the next minute or so

before the biggest Milestone and main

goal of this Mission stage separation at

t plus 2 minutes and 40 seconds we first

saw the flight data indicate that all

but three of super Heavy's engines had

been shut down just seconds later

Mission Control called out that booster

engine cut off had occurred you could

see the bottom of super heavy go from a

bright light to a dim point then at t

plus 2 minutes and 48 seconds the upper

stage engines ignited creating massive

ripples in the atmosphere just a second

later and the upper stage took

sucessfully disconnected from the

booster right away super heavy began its

flip and preparation for a return to the

ground as the camera panned to the

booster it completed its flip in just a

few seconds and began heading down range

however this also marked the first

visible error in the entire launch at t

plus 3 minutes in 15 seconds and the

seconds following you could see what

looked like some of the engines

attempted to light for the Boost back

burn a small explosion could be seen

followed by leaking fluids finally at t

plus 3 minutes and 20 seconds the entire

booster experienced a rapid unscheduled

disassembly this explosion shot debris

and created a massive white cloud before

the camera panned back to the Starship

upper stage which that entire time had

been gaining altitude 4 minutes in and

you could just barely see the Starship

upper stage at that point the vehicle

was traveling over 7,500 km an hour at

an altitude of 117 km the flight data

also highlighted that all six Raptor

engines were working properly over the

next 3 minutes the upper stage continued

to accelerate and get closer to its

suborbital destination this was up until

around 8 minutes into the long when you

could barely see the vehicle looking

very closely at T Plus 8 minutes and 8

seconds you can see large Ripples and

disruptions in the atmosphere indicating

that there could have been an explosion

also focusing on the flight data at the

exact same time you see that all six

engines stopped running and the vehicle

speed also stopped increasing on the

flight profile the Starship engine cut

off was scheduled to happen at T Plus 8

minutes and 33 seconds into the flight

the stream then cut to a screen that

said awaiting acquisition of signal

around that time the SpaceX commenters

were also under the impress impression

that the vehicle was still intact and

beginning its Journey around the earth

that was until they said in a quote

we've lost the data from the second

stage we heard in a call out that we

were in terminal guidance but we haven't

gotten any more data since then so we

think we may have lost the second stage

it was then revealed that the second

stage explosion was caused by the

activation of the flight termination

system as far as why this happened is

not exactly clear it could have been

that the upper stage was off track an

issue with the engines or a mistake

either way this marked the end of

starship's second integrated test flight

in the success for the company who

primarily wanted to complete stage

separation in the coming days we can

expect to hear a lot more from the

company as they determine exactly what
A Big Improvement

happened compared to the first launch of

Starship earlier this year the second

test flight showed quite a bit of

improvement in a few different areas if

the second launch had gone perfect the

booster would have completed a boost

back burn before simulating what a

landing would look like over the Gulf of

Mexico the upper stage would have

coasted around the globe for close to an

hour and a half until it reentered the

atmosphere and crash landed off the

coast of Hawaii in the Pacific Ocean in

reality an explosive ending is not the

ideal option but it's a realistic aspect

of spacex's methodology they're building

Starship at a rapid pace and nothing

provides more information than a real

test the second flight debut the hot

stage separation system and a new

electric thrust vector control or TVC

system for super heavy Raptor engines in

addition to reinforcements to the pad

foundation and a watercooled Steel Flame

deflector among many other enhancements

starting with the pad on the first

Starship flight test the concrete pad

was used which was destroyed by the

thrust of 33 Raptor engines the shot

Concrete in debris in every direction

damaging structures at stage zero and

flying hundreds of meters to try and fix

this problem between the first launch

and today SpaceX installed and tested a

massive water cooled steel plate looking

back at the beginning of today's flight

the water began flowing seconds before

engine ignition most importantly no

debris can be seen flying in the air as

Starship clears the tower unlike the

first flight this is a good sign that

the pad looks to have not only protected

the vehicle and surrounding structures

but stayed intact as well the goal for

SpaceX is to launch gather data and

launch again the state of the pad and

various infrastructure at stage zero

plays a big role in how fast the company

can prepare and launch again another

change that looks to have done a great

job was the new electric thrust vector

control system for the super heavy

Raptor engines during the first flight

there were a few issues that stuck out

as the main reasons for failure the

Raptor engines for example experienced

multiple problems throughout the test

multiple engines were disabled during

the launch sequence and even more fail

during the flight eventually the

spacecraft also lost rust Vector in

control of the Raptor engines which led

to the rocket starting an outof control

tumbling motion this time around all the

way until stage separation all 33 Raptor

engines looked to have been firing as

planned without any issues there was no

partial loss of power or small

explosions which were seen on the first

flight interestingly even without the

application of any new information

gained from this test flight the next

Starship prototype is already much more

advanced and upgraded than the rocket we

just saw left off with each new

prototype SpaceX is improving the design

and build of the vehicle as far as the

future of Starship it looks very

promising the next few weeks will be

full of review and talk as SpaceX

figures out exactly what worked and what

didn't they will then apply this

information to the next launch vehicle

and try to launch it as soon as possible

if the overall future test campaign goes

well actual people could climb aboard

Starship for the first time just a few

short years from now not long ago NASA

selected Starship to be the first crude

Lander for its Artemis Moon program here

the SpaceX vehicle will put astronauts

down near the lunar South Pole on the

Artemis 3 mission which is targeted to

launch in 2025 to add to this SpaceX has

already sold two private around the Moon

Starship missions as well well there

have been concerns regarding the future

timeline and whether or not SpaceX can

complete Starship in time this test

flight is a great step something we can

look forward to seeing in the coming

years SpaceX just completed the second

integrated test flight of Starship in it

didn't disappoint while not perfect they

managed to get through stage separation

which was the main goal of the mission

we will have to wait and see how it

progresses and the impact it has on the

space industry thank you very much for
