It seems as though technology is advancing at an extremely fast pace. Today, Rocket Lab has unveiled their Electron Launcher which is powered by a battery powered Rutherford rocket. the Rutherford rocket is almost entirely 3D printed, mostly of metals such as titanium. It will allow them to send payloads into Earth's orbit for a fraction of the cost that other companies can do so. It will cost just $4.9 million for private companies to utilize the Electron Launcher to send their satellites into space.
