Startup launches first 3D-printed battery-powered rocket (update)
Rocket Lab is a Lockheed Martin-funded startup that dreams of taking small satellites to space for an affordable price -- but it wants to do so using technology quite different than usual. See, the company has revealed that its engine called the "Rutherford" is (1) composed mostly of 3D-printed parts, and (2) uses batteries instead of liquid fuel. It will be paired up with the company's Electron launch system, and together they make up the first battery-powered rocket, or so the startup claims. Its batteries power the turbopumps that deliver propellant to the engine.*
