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.
Its Rutherford engines are the first electric-pump-fed engine to power an orbital-class rocket. [17] 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. [18]
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 ]
Harrisburg Intermodal Yard is a large rail yard located in Harrisburg, Pennsylvania. The yard originally was operated by the Pennsylvania Railroad and was known as the Lucknow Yard, later to be operated by Conrail , and since 1999, has been operated by the Norfolk Southern Railway .

Enola Yard is a large rail yard located in East Pennsboro Township, Pennsylvania, along the western shore of the Susquehanna River in Harrisburg, Pennsylvania.. Built in 1905 and expanded through the 1930s, Enola yard was the world's largest freight yard in 1956. [1]
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]
The Curie engine, named after Polish scientist Marie Skłodowska–Curie, is a small liquid-propellant rocket engine designed to release "small satellites from the constricting parameters of primary payload orbits and enables them to fully reach their potential, including faster deployment of small satellite constellations and better positioning for Earth imaging".
