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.
There are nine Rutherford engines on the first stage and one vacuum-optimized version on the second stage. [26] [27] [28] The first stage engines deliver 162 kN (36,000 lb f) of thrust and the second stage delivers 22 kN (4,900 lb f) of thrust. Almost all of the engines' parts are 3D printed to save time and money in the manufacturing process ...
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 ]
Rutherford Yard in 1970 when it was operated by the Reading Railroad. The yard was formerly operated by the Reading Railroad and later Conrail. Ownership was transferred from Conrail to the Norfolk Southern Railway in 1999. In the summer of 2000, Norfolk Southern retrofitted the yard for $31 million, its first major investment in the Harrisburg ...

Harrisburg is a census-designated place in, and the county seat of, Banner County, Nebraska, United States. [4] The population was 100 at the 2010 census . History
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]
This is a list of telephone area codes in the state of Nebraska. 308: Western Nebraska, including Grand Island and Kearney. 402/531: Eastern Nebraska, including Omaha and Lincoln, overlaid in 2011 [1] Under the original North American Numbering Plan of 1947, area code 402 covered all of Nebraska. Area code 308 was split off in 1954, and ...
