Relativity Space to Launch World's First Fully 3D-Printed Rocket Tonight.

Relativity Space will attempt to launch its 3D-printed Terran 1 rocket from Cape Canaveral for the third time on Wednesday night, with a 95% chance of favorable weather conditions. The rocket is designed to carry more than a ton of cargo into low Earth orbit and is aimed at the commercial launch market for small to mid-sized satellites. The test flight, nicknamed "Good Luck, Have Fun," won't carry any customer satellites but will attempt to fly into a 124-mile-high orbit about eight minutes after liftoff.
