Relativity Space Launches Terran 1: World’s First 3D Printed Rocket
The first launch of the Terran 1 rocket, designed by startup Relativity Space Inc., which is almost entirely made using 3D printing, took place.
Relativity Space’s Terran 1 rocket lifted off from Cape Canaveral in the state. Florida at 7:25 Moscow time, but a few minutes later, controllers reported a problem with the engine in the upper stage of the rocket. The company did not provide any other details about the problem.
A live feed of the launch showed that the upper stage engine’s ignition appeared to have cut out prematurely. However, Relativity’s team ended the review on a positive note, stating that the company has collected important data that confirms that its 3D printed manufacturing technology works.
The two-stage expendable Terran 1 rocket has become the largest 3D printed object sent into orbit. Terran 1 has nine 3D printed engines in the first stage and one in the second. In total, about 85% of the rocket is 3D printed, Relativity Space wants to increase this figure to 95% in future models. The use of 3D printing technology speeds up the construction of rockets and reduces their cost.
On March 8 and 11, the launch of the rocket was delayed due to problems with fuel temperature and weather conditions. It is not yet clear when the company will attempt another Terran 1 launch.
