This rideshare flight carries several payloads, including NASA's Advanced Composite Solar Sail System (ACS3). ACS3 is a technology demonstration mission tasked with deploying a composite boom solar sail.
Electron is a two-stage orbital expendable launch vehicle (with an optional third stage) developed by the American aerospace company Rocket Lab. Electron is a small-lift launch vehicle designed to launch small satellites and cubesats to sun-synchronous orbit and low earth orbit. The Electron is the first orbital class rocket to use electric-pump-fed engines, powered by the 9 Rutherford engines on the first stage.See Electron Details
Rocket Lab is an American aerospace manufacturer with a wholly owned New Zealand subsidiary. The company develops lightweight, cost-effective commercial rocket launch services. The Electron Program was founded on the premise that small payloads such as CubeSats require dedicated small launch vehicles and flexibility not currently offered by traditional rocket systems. Its rocket, the Electron, is a light-weight rocket and is now operating commercially. Electron currently launches from only Mahia Peninsula in New Zealand however they are currently looking into developing a facility in the US.INFO WIKI
Rocket Lab will launch a NASA technology demonstration satellite under an unconventional arrangement as the agency works on a more standardized approach for launching smallsats.
