Relativity's Third Attempt at Launching First 3D-Printed Rocket.

Relativity Space is set to launch the world's first 3D-printed rocket, Terran 1, on Wednesday, March 22, after two previous attempts were scrubbed due to weather, range, and technical issues. The rocket is 85% 3D printed by mass and the company aims to produce rockets faster and more efficiently than traditional processes. The demonstration mission, named "Good Luck, Have Fun," has no customer payload and will instead carry the company's first 3D-printed object. The long-term goal is to help establish human settlement on Mars.
