[edit on Wikidata]

Electron is a two-stage orbital expendable launch vehicle (with an optional third stage) developed by the American aerospace company Rocket Lab to cover the commercial small satellite launch segment (CubeSats).[3] Its Rutherford engines are the first electric-pump-fed engine to power an orbital rocket.[4]

In December 2016, Electron completed flight qualification. The first rocket was launched on 25 May 2017,[5] reaching space but not achieving orbit due to a glitch in communication equipment on the ground.[6] During its second flight on 21 January 2018, Electron reached orbit and deployed three CubeSats.[7] The first commercial launch of Electron, and the third launch overall, is expected to occur in the next launch window, which will open from 23 June to 6 July 2018.[8]

Design

Electron uses two stages with the same diameter (1.2 m, 3 ft 11 in) filled with RP-1/LOX propellant. The main body of the rocket is constructed using a lightweight carbon composite material.[9]

Both stages use the innovative Rutherford rocket engine, the first electric-pump-fed engine to power an orbital rocket.[4] There are nine Rutherford engines on the first stage and one vacuum-optimized version on the second stage.[10][11][12] The first stage engines deliver 162 kN (36,000 lbf) of force and the second stage delivers 22 kN (4,900 lbf) of force. Almost all of the engines' parts are 3D-printed to save time and money in the manufacturing process.[4][9]

Rocket Lab has also developed an optional third stage designed to circularize the orbits of its satellite payloads. The kick stage employs a new rocket engine, named Curie, that is capable of performing multiple burns, uses an unspecified "green" monopropellant, and is 3D printed. It was first used during Electron's second flight.[13]

Intended usage

Electron is designed to launch a 150 to 225 kg (330 to 495 lb) payload to a 500 km (310 mi) Sun-synchronous orbit, suitable for CubeSats and other small payloads.[1][14] The cost is less than US$6 million,[15] a price point that the company hopes will allow it to attract one hundred launches per year.[3][15][16][17][18][19] Customers may choose to encapsulate their spacecraft in payload fairings provided by the company, which can be easily attached to the rocket shortly before launch.[20]


The price for delivering up to 150kg to a 500km Sun-synchronous orbit is about $5 million per launch, which offers the only dedicated service at this price point.[21]

Moon Express contracted to launch a lunar lander on an Electron to compete for the Google Lunar X Prize.[22] None of the contenders met the prize deadline, but the launch remains scheduled.[23]

Launch sites

The Mahia launch site under construction in 2016

The rocket is launched from Rocket Lab Launch Complex 1 on Mahia Peninsula, New Zealand.[9] The launch pad's remote and sparsely populated location is intended to enable a high frequency of launches.[9] The rocket and launch pad were both privately funded, the first time all parts of an orbital launch operation were entirely run by the private sector (other private spaceflight companies lease launch facilities from government agencies or only launch suborbital rockets).[9][14]

Rocket Lab is also planning launches from Kennedy Space Center and the Pacific Spaceport Complex.[24][25]

Launch statistics

The Electron has flown two times over two years. There has been one success and one failure. The initial test flight, called "It's a Test", failed due to a glitch in communication equipment on the ground, but the follow-up mission, called "Still Testing", became the first successful flight.

1 25 May 2017, 04:20[24] Mahia LC-1 "It's a Test" Rocket Lab (flight test) LEO Failure
The rocket successfully launched and performed first stage separation and fairing separation. After reaching an altitude of about 224 km (140 mi), the telemetry feed to the range safety officer was lost and the rocket was destroyed by range safety.[26][27] Post-flight analysis determined the issue to be a ground equipment failure rather than a problem with the rocket.[28]
