Rocket Lab Electron

Electron is a two-stage, partially recoverable orbital launch vehicle developed by Rocket Lab, an American aerospace company with a wholly owned New Zealand subsidiary. Electron was developed to service the commercial small satellite launch market. 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.

In December 2016, Electron completed flight qualification. The first rocket was launched on 25 May 2017 in a flight called "It's a Test", reaching space but not achieving orbit due to a glitch in communication equipment on the ground. During its second flight on 21 January 2018, Electron reached orbit and deployed three CubeSats, in a mission called "Still Testing". The first commercial launch of Electron, and the third launch overall, occurred on 11 November 2018, in a mission called "It's Business Time". Since then, Electron has launched successfully 37 times, with an additional 4 failures, for a grand total of 41 launches.
