SpaceX is starting to move on from the world's most successful rocket

On a typical week in 2026, SpaceX launches a Falcon 9 rocket roughly every three days. The booster climbs out over the Atlantic, separates, flips, and comes back to land on a drone ship or concrete pad with mechanical precision. The upper stage keeps going, hauling Starlink satellites, commercial payloads, or crew to the International Space Station. By the time most people read about it, it's already done, already ordinary. That ordinariness is the point: Falcon 9 has made orbital launch feel routine in a way no rocket before it ever did.

But something is shifting at SpaceX's facilities in Boca Chica, Texas, and Hawthorne, California. The company that perfected Falcon 9 is now building something far bigger, far stranger, and far more ambitious. Starship, standing roughly 400 feet tall when stacked with its Super Heavy booster, is not yet routine. It still explodes on occasion. It still draws crowds who watch it rise and wait to see if it will survive. But when it works, it works in a way that makes even Falcon 9 look like a delivery van compared to a semi-truck.

The transition from Falcon 9 to Starship is underway. It is not complete, and it is not clean. But it is real, and it is changing what space launch means.

The Record Falcon 9 Set

To understand what SpaceX is moving toward, it helps to understand what Falcon 9 built. Since its first flight in 2010, the rocket has accumulated numbers that border on the absurd. As of May 2026, Falcon 9 has completed 648 launches with a 99.54 percent success rate. That record includes 645 full successes, two in-flight failures, one pre-flight failure, and one partial failure. The Block 5 variant, the final hardware iteration, has flown 579 times with a 99.83 percent success rate, suffering just one failure across more than half a thousand flights [1][2].

The booster recovery program turned a logistical liability into a competitive advantage. SpaceX has landed boosters 608 times across 621 attempts. Fifty-four boosters have flown multiple missions, and the workhorse booster B1067 has flown 34 separate missions, a record that would have seemed implausible when the company was still learning to land rockets on barges. At $74 million per launch in 2026, Falcon 9 offers a combination of reliability and price that no competing rocket comes close to matching [1][2].

In 2024 alone, SpaceX completed 133 successful Falcon 9 flights, plus one Falcon Heavy mission. That single company's launch cadence accounted for more than half of all orbital launches globally that year. The previous record for a single rocket in a single year belonged to Russia's Soyuz-U, which managed 47 launches in 1979. SpaceX shattered that figure with 60 Falcon 9 launches in 2022, a record that keeps growing [2].

These are not just statistics. They represent a fundamental shift in what a private company could achieve in space, and they established SpaceX as the dominant force in commercial launch. But the numbers also define a ceiling. Falcon 9 can lift 22.8 metric tons to low Earth orbit in its expendable configuration. That is enough for most commercial satellites, for crew missions, for cargo. It is not enough for what SpaceX has in mind.

Why Starship Exists

Starship was designed to solve different problems. The rocket that Elon Musk called "the most complex and advanced rocket ever made" is intended to be fully reusable, with both the Super Heavy booster and the Starship upper stage designed to fly multiple missions without structural refurbishment between flights. That ambition drives the design in ways that make it unlike anything SpaceX has built before.

The current configuration, Block 1, delivers just 15 metric tons to low Earth orbit, less than Falcon 9's capacity [3]. That seems like a step backward. It is, temporarily. Block 2 is designed to increase that figure to 35 metric tons. Block 3 targets 100 metric tons. Block 4, still on the roadmap, aims for 200 metric tons. Each block represents a set of structural, engine, and manufacturing improvements that SpaceX is working through incrementally, learning from each flight [3].

The engine count alone signals the scale: Starship's Super Heavy booster carries 33 Raptor engines, burning liquid methane and liquid oxygen. The Starship upper stage adds another six Raptors. That is 39 engines on a single vehicle, more than any orbital rocket in history. The sheer thrust capacity, if it can be made reliable, opens possibilities that Falcon 9 never could touch.

Starship's development cost has exceeded $15 billion, a figure that reflects both the technical difficulty of building a fully reusable super heavy-lift vehicle and the willingness of SpaceX to absorb years of losses while iterating toward reliability [3]. The per-launch cost in expendable mode sits at $100 million, currently more expensive than Falcon 9. The promise, however, is that full reuse will dramatically reduce that cost. SpaceX's bet is that mass production and rapid reuse will eventually bring Starship's per-flight price well below Falcon 9's, even as the vehicle carries far more payload.

The Messy Middle

Here is what makes the transition complicated: Falcon 9 is still winning. SpaceX is not retiring its most reliable vehicle while it debugs its newest one. Instead, the company is flying both, letting Falcon 9 generate revenue and prove out operational excellence while Starship works through its own development arc.

As of October 13, 2025, Starship had launched 11 times, with six successes and five failures. The most recent flight, IFT-5, completed a successful catch of the Super Heavy booster using the mechanical arms at the launch site, a maneuver that looked like science fiction and demonstrated that the recovery architecture SpaceX has been designing is physically possible [3]. Each flight has added data. Each failure has cut a path that the next flight avoids.

The contrast with Falcon 9's record is stark, but it is also misleading if taken out of context. Falcon 9 took years to reach its current reliability. Early Falcon 1 and Falcon 9 flights failed. The booster landing program had explosions and missed droneship landings. The path to 99.83 percent Block 5 reliability ran through years of iteration. Starship is still in that early phase, and the 11-flight dataset does not yet tell you what Starship will be.

What it does tell you is that the flight rate is accelerating. SpaceX is building and flying new vehicles rapidly, testing and discarding hardware configurations, learning from each attempt. The cadence of Starship flights is increasing, and the interval between flights is shrinking.

The NASA Contract and the Bigger Picture

The clearest near-term validation of Starship's viability comes from NASA. The agency selected Starship as the Human Landing System for Artemis III, the mission intended to return astronauts to the lunar surface for the first time since Apollo. The docking test is scheduled for 2027, with a crewed lunar landing targeted for 2028 [3].

That contract matters for reasons beyond the prestige. NASA does not award human landing system contracts to vehicles it considers unproven. The agency's confidence in Starship's trajectory, even at this stage, reflects the technical progress SpaceX has demonstrated and the agency's own operational familiarity with Falcon 9. SpaceX knows how to deliver hardware that meets NASA's standards. The question is whether Starship can reach those standards on the timeline NASA has set.

Beyond Artemis, SpaceX has proposed using Starship for interplanetary missions, including crewed flights to Mars. That vision requires in-orbit refueling, a capability that does not yet exist but that SpaceX has designed the vehicle to support [3]. The proposal is ambitious enough that serious analysts treat Mars missions as a long-term goal rather than an imminent one. But it defines the scale of what Starship is meant to eventually do.

What the Transition Actually Means

The phrase "moving on from" the world's most successful rocket risks implying a clean handoff, a moment when Falcon 9 stops flying and Starship takes over. That is not what is happening, and it is not what SpaceX is planning. Falcon 9 remains the backbone of the commercial launch market, and there is no announced retirement date. The vehicle is still being flown, still being improved in marginal ways, still generating the revenue and operational expertise that funds Starship's development.

The transition is better understood as a shift in where SpaceX is investing its future. Engineering talent, manufacturing capacity, launch infrastructure, and development capital are all flowing toward Starship in increasing proportions. Falcon 9 is being maintained and flown, but it is not the vehicle where the company's ambitions live anymore.

This is the normal arc of aerospace development. The DC-3 was a magnificent airplane, but the jet age eventually came. The space shuttle was a marvel of its era, but it could not do what Falcon 9 does, and Falcon 9 cannot do what Starship is being built to do. Each vehicle defines its era, and then the next vehicle begins to define the one that follows.

Falcon 9's era is not over. The rocket that proved reusability could work, that made Starlink possible, that restored American human spaceflight, is still flying at a pace no other rocket matches. But the future, the one SpaceX is building toward with every Starship test flight, is arriving just over the horizon. When it arrives, it will arrive big.
