spacex's founder and CEO, Elon Musk.
And in today's episode, we'll be discussing the groundbreaking
test flight of spacex's Starship system, which includes a
super-heavy booster booster 7 and the Starship upper stage
ship 24. Now this ambitious test flight
showcase the system's impressive capabilities of a Make the push,
the boundaries of Rocket engineering setting a new record
for thrust and testing the structural Integrity of both the
ship ship 24. And booster.
Seven will explore the various stages of this historic test
flight including the successful endurance of Max Q.
The Innovative plan for booster recovery and also the ultimate
goal of revolutionising space travel through the rapid
turnaround times and sustainable space exploration of the
Starships. System.
A join us as we take a dive into the challenges.
Faced during the test flight, the invaluable insights gained
at the potential impact of this system on the future of space
travel. Now, the Starship system,
booster 7-inch ship 24, it's a groundbreaking test flight.
That happened today in this challenge is the limits of
Rocket technology SpaceX and it's Relentless pursuit of
revolutionising space travel recently conducted an ambitious.
Test flight for its Starship system.
Now, aiming to push the boundaries of Rocket
engineering, the test flight. Showcased, The Staggering
capabilities are the Starship system.
While overcoming numerous technical challenges to get it
into the air, the test flight started with the pre-launch
cooling of the 33 Raptor engines on booster 7 now at T minus 16
seconds or 16 minutes and 40 seconds.
Small amount of propellant flow through the engines.
Gradually, reducing their temper.
Archer to prevent thermal shock and potential damage to the
intricate components within. And this cautious procedure
mirrors the cooling approach taken with the tank farm, and
propellant loading systems at Starbase Texas.
And as the countdown progressed T minus, 47 seconds, Mark the
beginning of the fluid interfaces vent down sequence.
This crucial step involve venting any remaining.
Propellant from the lines, connecting the booster in the
ship quick, quick. Disconnect the qds to minimize
damage during liftoff at T-minus eight seconds, the Raptor engine
startup sequence, commenced in the 33, Raptor two engines,
ignited, in a staggered manner before ramping up to flight
thrust levels. Now, for this test flight, the
edges were initially limited to around 90 percent thrust.
And despite the Restriction, booster 7 broke records by
generating an astounding 67. 8,000, kilonewtons of thrust
surpassing the Soviet Union's N1 rocket, which held the previous
record. It 45 thousand four hundred
kilonewtons of thrust. Now with the hold-down clamps
released booster 7 and ship, 24, lifted off from the pad, it T.
Minus 0 simultaneously, the ship QT, arm responsible for fueling
ship 24, this engaged and retracted to avoid damage from
the departing rocket. And it's exhaust.
Now as the full stack began, its gravity turn the vehicle, clear?
The tower and pitched down range toward the Gulf of Mexico and
booster seven experience. The loss of five to six Raptor
engines during the first stage Ascent but successfully endured
Max Q. This is the period of peak
aerodynamic stress around 55 seconds.
After liftoff at this Milestone tested, the structural Integrity
of both 24 and and booster seven.
Now unfortunately, though the vehicle began to spin and was
ultimately destroyed by the flight termination system,
despite the premature end, the test flight provided invaluable
insights into the performance of the Starship system.
Now in a hypothetical full mission, profile booster 7 would
have continued burning until around the t plus 2 minutes and
49 seconds Mark at which point all 33 engines would have.
Down four booster engine cutoff. The vehicle would have then been
at an altitude of approximately 64 kilometers or 40 miles up and
climbing rapidly ship. 24 would have separated from booster, 74
seconds. Later coasting away from the
booster for five seconds before igniting.
It's six wrapped or two engines. Now this ambitious test flight
was designed without the intention of placing ship 24 in
a stable orbit. Now instead the Engines have
what a fire. Just short of full orbital
insertion. Sending the spacecraft on a
trajectory to re-enter over the Pacific Ocean near Hawaii.
Now, meanwhile, booster 7 would have flipped around just after
stage separation in reignited. Its inner 13 engines for What's
called the Boost back burn, which would have occurred a
little over three minutes after liftoff.
Now, this burn would have lasted about 55 seconds.
Directing the booster towards a splash Down in the Gulf of
Mexico, roughly 19 miles off the Texas coast.
Now, unlike the Falcon 9 though booster 7 wasn't designed to
perform an entry burn as the stainless steel construction
offers great temperature resistance compared to the
aluminum used in Falcon 9 instead, booster 7 would have
relied on its for grid, fins for orientation and steering towards
the targeted, Landing zone of the Gulf of Mexico.
Now, the vehicle was expected to go.
Go transonic around seven and a half minutes after liftoff with
a final Landing burn. Starting around 10 seconds later
at this Landing burn lasting approximately 23 seconds would
have used the boosters three innermost engines, bring you the
booster to an impact speed of about eight point five
milliseconds which is 19 miles per second.
Sorry 19 mph upon hitting the water.
The water and 10 seconds after Splashdown boost.
Seven would have tipped over onto its side in the event.
That the tip over did not cause the vehicle to break apart vent.
Veils on both propellant tanks, would have opened to allow water
to flood the vehicle sinking. It intentionally, they don't
plan to recover those now. SpaceX is ultimate goal is to
fly super heavy boosters, back to the launch site and use the
massive Chopsticks mounted on the launch Tower to catch the
boosters as they come in for a landing.
Now, this Innovative approach could enable Turnaround times
for the boosters as no recovery assets would be needed in the
vehicles could be placed directly back onto the launch
Mount shortly after landing. Now, assuming ship 24 had
reached engine cutoff, it would have coasted for slightly over
an hour. And during this time, the
vehicle would have vented all, but nearly 14, tons of
propellant, that's 10, tons of locks liquid oxygen and four
tons of CH4 And to maintain the correct amount of ballast during
re-entry. That would have happened if the
vehicle had survived. The nearly 10 minute long
re-entry, phase shift 24 would have gone, transcending, just
under 1 & a half hours after lifting off from Starbase for
this test flight don't recovery. Attempt would have been made for
ship 24. Unlike booster 7 ship 24 would
not have performed a landing burn.
It was expected to impact the ocean at terminal velocity.
Approximately one and a half hours after liftoff, had the
mission progressed that far. Unfortunately, they did have to
terminate the flight with the flight termination system over
the Gulf of Mexico and they lost both the booster and the ship
during this flame. Now, despite the challenges
faced during the test flight, the data in the experience,
gained from the event will contribute to the development of
future Starship missions with each new test.
Each new booster, each new ship, SpaceX takes one step closer to
transforming space travel, making the dream of affordable,
huge space, travel, huge, Rockets affordable, and
sustainable for the future of all humankind.
