Rutherford is a liquid-propellant rocket engine designed by aerospace company Rocket Lab [8] and manufactured in Long Beach, California. [9] The engine is used on the company's own rocket, Electron. It uses LOX (liquid oxygen) and RP-1 (refined kerosene) as its propellants and is the first flight-ready engine to use the electric-pump-fed cycle.
[35] [40] Later, Rocket Lab abandoned the plan to catch the stage with a helicopter, and will use ocean landing instead. One recovered Rutherford engine passed five full-duration hot fire tests and is declared ready to fly again. [41] Rocket Lab's 40th Electron mission successfully reused a refurbished Rutherford engine from a previous flight ...
Rocket Lab's Electron Rocket The Rutherford engine uses pumps driven by battery-powered electric motors rather than a gas generator , expander , or preburner . [ 107 ] The engine is fabricated largely by 3D printing , using electron beam melting , [ 108 ] whereby layers of metal powder are melted in a high vacuum by an electron beam. [ 109 ]
Meanwhile, Rocket Lab, which has already established itself as a thriving launch company with its Electron rocket, has signed its first customer for its larger Neutron launch vehicle. The customer ...

It was Rocket Lab's first mission failure in over two years. The previous mission, the Electron's 41st, failed about 2 1/2 minutes into its flight as it carried a satellite from synthetic-aperture ...
The space flight upstart posted strong quarterly earnings and gave some big updates for its new product lines.
As of December 2020, the only rocket engines to use electric propellant pump systems are the Rutherford engine, [2] ten of which power the Electron rocket, [2] and the Delphin engine, five of which power the first stage of Astra Space's Rocket 3. [3] On 21 January 2018, Electron was the first electric pump-fed rocket to reach orbit. [4]
