CAPE CANAVERAL, July 14 — The Falcon 9 rocket has quietly become the workhorse of the modern space age, and its track record now speaks for itself. As of October 2023, SpaceX’s partially reusable launch vehicle had completed over 250 launches, with a single first-stage booster flying 15 times. That reuse rate is the practical upshot of a decade of engineering refinement, and it has fundamentally changed how often — and how cheaply — we can get things to orbit.
Think of the Falcon 9 like a delivery truck that you can drive back to the warehouse after dropping off the package. The rocket is a two-stage-to-orbit medium-lift vehicle, standing 70 meters tall.
Its first stage is powered by nine Merlin engines, each generating 190,000 pounds of thrust. That cluster of engines lifts the whole stack off the pad, burns for about two and a half minutes, then separates and flies itself back to Earth for a landing. SpaceX achieved its first successful booster landing on December 21, 2015, at Cape Canaveral Air Force Station.
Before that, the industry norm was to let the first stage fall into the ocean — essentially throwing away the most expensive part of the rocket after every single flight. The Falcon 9 changed that calculus.
The practical upshot: a rocket that can fly again, even if it needs significant refurbishment between flights.
What It Carries
The Falcon 9 can deliver 22.8 metric tons to low Earth orbit. That capacity has made it the go-to vehicle for a wide range of missions. SpaceX has used it for crewed flights to the International Space Station — the first crewed mission launched in May 2020 — as well as for satellite deployment and cargo resupply runs.
The rocket’s most frequent customer, though, is SpaceX itself. The company’s Starlink satellite internet constellation, which had over 4,500 satellites launched as of October 2023, relies heavily on Falcon 9 launches.
Each Starlink mission packs dozens of satellites into the payload fairing, and the booster reuse means SpaceX can launch these batches frequently without building a new first stage every time.
The Refurbishment Reality
Reusability is not free. The Falcon 9’s boosters require significant refurbishment after each landing, including engine replacements. That is a real cost, both in time and money.
Blue Origin’s New Glenn rocket, still in development, aims to minimize that refurbishment with its own design choices. For now, though, the Falcon 9 remains the only operational orbital-class rocket that regularly lands and reflies its first stage.
The rocket first launched in June 2010, more than a decade before its first crewed flight. That long development arc — from an experimental vehicle that sometimes exploded on the pad to a mature launch system with a reuse record of 15 flights — is the story of iterative engineering at its most visible.
What to Watch Next
The Falcon 9 is not new, but its impact is still unfolding. As of October 2023, the rocket continues to fly at a high cadence, launching Starlink satellites, government payloads, and commercial missions. The question is whether its refurbishment costs will eventually cap its economic advantage, or whether further refinements will push the reuse record even higher.
For now, it remains the most reliable way to get a payload to orbit — and the clearest example yet that reusable rockets are not a novelty, but a new baseline.
