SpaceX readies Starship for launch rehearsal and orbital test flight
More than twice the power of the rockets that reached the Moon
Mark
So SpaceX is saying they'll do a rehearsal next week and then a real test flight the week after. How confident should we be that actually happens on that timeline?
Mimi
They're being careful with the language—they said "pending regulatory approval," which is the real gate. The FAA has to sign off before the orbital test happens. The rehearsal might be more flexible.
Luke
Right, and we should note that the source doesn't tell us what "launch rehearsal" actually means operationally. Is it a full countdown? A partial one? We know what static fire is from February, but this rehearsal is a different thing and the reporting doesn't define it.
Mimi
Fair point. What we do know is they've already tested all 33 engines on the booster while it was bolted down. So the basic propulsion works.
Mark
And this is the rocket NASA picked for the Moon landings, correct?
Mimi
Yes. NASA will take astronauts to lunar orbit themselves in November 2024 using their own Space Launch System. But Starship is what will actually land them on the Moon for Artemis III, which is 2025 at the earliest.
Luke
Though "at the earliest" is doing a lot of work there. Space timelines slip. We should be clear that 2025 is the target, not a guarantee.
Mark
How does Starship compare to what we used to go to the Moon?
Mimi
It's more than twice as powerful as Saturn V. Seventeen million pounds of thrust versus Saturn V's roughly seven or eight million.
Luke
The source says "more than double," so we're being precise with that language. It's a real difference in capability.
Mark
And SpaceX thinks they can refuel it in orbit and send it to Mars?
Mimi
That's the vision. Launch one Starship to orbit, launch another to meet it, transfer fuel, and then the first one continues to Mars or beyond. It's elegant if it works.
Luke
It's also untested. We're talking about a concept, not something they've demonstrated yet. The reporting is clear about that—it's what SpaceX "foresees," not what they've done.
Der Puls
- The most powerful rocket ever built is fully stacked and standing on a Texas launchpad, closer to flight than it has ever been.
- A launch rehearsal — a full countdown without ignition — is set for next week, with the actual test flight potentially following just days later if the FAA grants approval.
- NASA has already staked part of its Artemis lunar program on Starship, selecting it to land astronauts on the Moon as early as 2025, raising the stakes of every milestone.
- SpaceX's vision of in-orbit refueling — one Starship topping off another in space before heading to Mars — means this test flight is not an endpoint but a first step in a much longer journey.
- Blue Origin, China, and Russia are all developing rival super-heavy rockets, making the coming weeks a pivotal moment in a quiet but consequential race for deep-space capability.
At a launchpad on the Texas coast, humanity's most powerful rocket stands assembled and waiting — a machine built not merely to reach orbit, but to carry the species toward the Moon, Mars, and the open question of what comes next. SpaceX's Starship, generating twice the thrust of the Saturn V that carried Apollo astronauts to the Moon, is preparing for a launch rehearsal and its first integrated test flight, pending federal approval. The moment sits at the intersection of engineering audacity and regulatory patience, a reminder that the distance between ambition and liftoff is measured not only in miles, but in process.
SpaceX announced Thursday that its Starship rocket is fully assembled at Starbase in Texas and is moving toward two critical milestones: a launch rehearsal next week and, if federal regulators approve, a first integrated test flight the week after. The images shared on social media showed the completed vehicle standing on the launchpad — a 230-foot machine consisting of a Super Heavy booster fitted with 33 Raptor engines below, and a reusable crew-and-cargo capsule above.
The numbers surrounding Starship are difficult to absorb quietly. It produces 17 million pounds of thrust — more than double what the Saturn V generated during the Apollo era — making it substantially more powerful than NASA's own Space Launch System, which took over a decade to develop. In February, SpaceX validated all 33 engines firing together in a static fire test, a ground-anchored ignition that confirmed the booster's capability without allowing liftoff.
NASA has already woven Starship into its plans for returning humans to the Moon. The agency selected the vehicle to carry astronauts to the lunar surface for Artemis III, targeted for 2025 at the earliest, while NASA's own Space Launch System will handle an earlier crewed orbital flight in late 2024. Beyond the Moon, SpaceX envisions Starship being refueled in orbit by a second vehicle, enabling missions to Mars that no single launch could sustain alone.
Before any of that can unfold, the Federal Aviation Administration must grant clearance for the orbital test. The rehearsal — a full countdown and systems check without ignition — serves as the final validation before the real attempt. Competitors including Blue Origin, China, and Russia are developing their own super-heavy rockets, but Starship's combination of scale, thrust, and reusability positions it as something potentially transformative. The weeks ahead will begin to reveal whether the engineering is equal to the vision.
SpaceX had stacked its Starship rocket fully at its Texas facility and was preparing to move forward with two critical milestones: a launch rehearsal scheduled for the following week, and what could be the vehicle's first integrated flight test the week after that, pending approval from federal regulators. The company announced the plan on Thursday through social media, sharing images of the assembled machine standing on the launchpad at Starbase.
The Starship represents the most powerful rocket system ever constructed. It stands 230 feet tall and consists of two main components: the Super Heavy booster on the bottom, fitted with 33 Raptor engines, and the reusable capsule on top designed to carry crew and cargo. In February, SpaceX had already demonstrated the booster's capability by conducting a static fire test—a ground-anchored engine test that prevented the vehicle from actually lifting off—which validated all 33 engines working in concert.
The rocket's raw power is staggering. It produces 17 million pounds of thrust, more than twice what the Saturn V rockets generated during the Apollo program that sent humans to the Moon in the 1960s and 1970s. This makes Starship substantially larger and more capable than NASA's Space Launch System, the agency's own heavy-lift rocket that has taken more than a decade to develop.
NASA has already committed to using Starship for a crucial mission. The space agency selected the vehicle to transport astronauts to lunar orbit as part of the Artemis III mission, currently targeted for 2025 at the earliest. NASA itself will conduct an earlier crewed test flight to lunar orbit in November 2024 aboard the Space Launch System, but Starship will handle the actual descent and surface operations when Artemis III launches.
SpaceX's ambitions extend far beyond the Moon. The company envisions a future in which a Starship reaches orbit, receives a refueling from a second Starship launched separately, and then continues onward to Mars or deeper into space. This in-orbit refueling concept would enable long-duration missions that a single launch cannot accomplish alone.
The path forward depends on regulatory clearance. The Federal Aviation Administration must grant approval before SpaceX can proceed with the orbital test flight. The launch rehearsal itself—a full countdown and systems check without actual ignition—serves as a final validation before attempting the actual flight.
SpaceX is not alone in pursuing super-heavy launch capability. Blue Origin is developing the New Glenn rocket. China is working on the Long March 9. Russia has the Yenisei in development. But Starship's combination of size, power, and reusability sets it apart as a potential game-changer in how humanity accesses space. The coming weeks will show whether the engineering matches the ambition.
