SpaceX has set a launch target of May 27th, 2025 at 2330 UTC
for Starship Flight 9. The launch will take place at *
Base, the company's private sitein Buccateeka, Texas.
However, the mission is still waiting for a green light from
the Federal Aviation Administration, which must first
conclude its investigation into the failed Starship Flight 8.
This flight will use Ship 35 andSuper Heavy Booster 14-2.
(00:24):
Ship 35 is a newer version of the vehicle known as a Block 2
prototype. Booster 14-2 is notable because
it previously flew on Flight 7 and will now be launched again,
making it the first reused SuperHeavy booster.
Flight 9 will not include a catch attempt with the launch
tower arms. Instead, Booster 14-2 will
attempt to control descent and soft splashdown in the Gulf of
(00:45):
Mexico. Ship 35 will continue into
orbit, re enter Earth's atmosphere and aim for a water
landing in the Indian Ocean. Starship has flown before, but
none of those tests combined orbital insertion, full re
entry, and controlled recovery of both stages.
If successful, Flight 9 will prove the system can work from
start to finish. The booster will use 33 Raptor
(01:07):
engines, with 29 of them having flown before.
The Raptor 3 engine is a key upgrade.
It's lighter, simpler to produce, and generates up to 280
tons of thrust per engine. With a specific impulse of 350
seconds. Each engine weighs about 1525
kilograms. Ship 35 has 6 Raptor engines,
(01:27):
three designed for sea level operations and three vacuum
optimized for use in space. Both stages burn a cryogenic mix
of liquid methane and liquid oxygen known as metalox.
These fuels are cooled near their freezing points,
increasing energy density and improving efficiency.
Thermal protection is another key area of testing.
(01:47):
Starship's black heat shield tiles can survive temperatures
up to 1400°C. Flight 9 will include
experiments using fewer tiles, experimental active cooled
systems, and possibly ablative materials, all aimed at
improving reusability while saving weight.
The flight profile starts with lift off from Starbase Texas.
(02:08):
Once the booster separates, it will turn, reignite some engines
and splash down in the Gulf. Ship 35 will continue into
orbit, coast for several hours and then perform a re entry burn
to slow down before attempting asoft water landing in the Indian
Ocean. SpaceX may also include test
payloads. These could include simulated
(02:28):
Starling satellites or structural mass simulators.
One goal is to fly a trajectory that stresses the vehicles
control flaps to gather real world data for future design
updates. Flight 9 is also a test of
durability. Reusing Booster 14-2 checks
whether the hardware can withstand stress from multiple
missions. Even though the booster won't be
(02:48):
recovered for reuse this time, bringing it down softly allow
SpaceX to inspect its performance and tweak future
designs. The new heat shield materials
and experimental designs on Ship35 help SpaceX figure out what
works best. Some tests will stress the
vehicle in ways it hasn't been tested before, especially on re
entry. These real world trials are the
(03:10):
only way to validate systems before using them on operational
missions. SpaceX still needs regulatory
approval before it can fly. The FAA is reviewing what went
wrong in Flight 8 before giving permission for this next test.
Until that process ends, the May27th date is a target, not a
guarantee.
