Giant robots powered by AI are being trained to 3-D print rockets to take humans to space

A new company founded by two former USC students wants to change the way rockets are made by using enormous 3-D printers. The company's initial project is called Terran-1, a 100-foot tall rocket that initially will carry satellites of up to 2,800 pounds into orbit around the earth. The current plan is to radically simplify manufacturing, using 100 times fewer parts to create a rocket that's so easy to manufacture, an AI can handle it. Relativity Space is based in Los Angeles, where its working on building a rocket that could launch as early as 2021. Relativity's founders see 3-D printing as the key to the company's success.
