Falcon 9 vs Falcon Heavy
Falcon Heavy is built from three Falcon 9 first stages joined together, which roughly triples liftoff thrust. Successive Falcon 9 upgrades made the single-core rocket capable enough for almost every payload, so Falcon 9 flies constantly while Falcon Heavy stays a specialist that launches once or twice a year.

Falcon 9
Falcon 9 is SpaceX's two-stage rocket, with a reusable first stage, 676 liftoffs through August 12, 2026, and crew, science, and Starlink roles.

Falcon Heavy
Falcon Heavy is SpaceX's three-core heavy-lift rocket, flown 12 times since its 2018 debut with launches including Psyche, Europa Clipper, and GOES-U.
Key differences
- Launch rate: Falcon 9 had made 676 physical liftoffs through August 12, 2026, including 94 in 2026. Falcon Heavy has flown 12 times since 2018, most recently ViaSat-3 F3 in April 2026, with NASA's Roman Space Telescope targeted for August 30, 2026.
- Payload: SpaceX publishes 63,800 kg to low Earth orbit for a fully expendable Falcon Heavy, against 22,000 to 22,800 kg for a fully expendable Falcon 9. SpaceX does not publish one current Falcon 9 limit for recovery missions because the available performance depends on the trajectory. The Heavy margin matters for high-energy missions such as Europa Clipper.
- Recovery: Falcon Heavy's two side boosters land in tandem and have succeeded on all 20 attempts. The center core is harder: it has been recovered once, in 2019, and never reached port, so SpaceX now expends it.
- Price: SpaceX's current price sheet quotes only Falcon 9, at 74 million dollars through 2026. The last published Falcon Heavy list price, 97 million dollars set in a 2022 inflation adjustment, was about 45 percent above the 67 million Falcon 9 then cost. Government awards that bundle mission services run much higher, such as about 178 million dollars for Europa Clipper.
