Falcon 9 vs Electron

Electron carries 300 kg to low Earth orbit, under two percent of a Falcon 9 load, yet Rocket Lab had flown it 92 times through August 6, 2026. Small satellites can ride cheaply as Falcon 9 rideshare passengers, but a dedicated small rocket picks the exact orbit and the launch date, and that is the niche Electron owns.

Key differences

  • Scale: Electron stands 18 m and lifts 300 kg. Falcon 9 stands 70 m, and SpaceX's public documents give 22,000 to 22,800 kg to low Earth orbit fully expendable; recovery performance is mission-specific.
  • Service model: Electron sells one customer the orbit and the schedule. Falcon 9's Transporter rideshares are far cheaper per kilogram but drop payloads where the bus is already going.
  • Technology: Electron's airframe and tanks are carbon fiber composite, and its Rutherford engines, largely 3D printed, were the first electric-pump-fed rocket engines to fly.
  • Price: SpaceX lists Falcon 9 at 74 million dollars through 2026, roughly ten times what an Electron mission costs. Falcon 9 lifts nearly 60 times the mass, so per kilogram delivered the big rocket is about six times cheaper.
