Rocket Lab Electron (Neutron planned)

Electron is a two-stage, expendable orbital launch vehicle developed by Rocket Lab, a publicly traded aerospace manufacturer and launch service provider. Servicing the commercial small satellite launch market, it is the third most launched small-lift launch vehicle in history. Its Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket. Electron is often flown with a kickstage or Rocket Lab's Photon spacecraft. Although the rocket was designed to be expendable, Rocket Lab has recovered the first stage twice and is working towards the capability of reusing the booster. The Flight 26 (F26) booster has featured the first helicopter catch recovery attempt. Rocket Lab has, however, abandoned the idea of catching Electron.
