World's first 3D-printed rocket launches successfully, but fails to reach orbit: Watch liftoff
In a third attempt, the world’s first 3D-printed rocket made it off the launch pad Wednesday night but failed to reach orbit and eventually crashed into the Atlantic Ocean in a key test flight by a California-based aerospace startup.
Relativity Space's Terran 1 booster lifted off at 11:25 p.m. EDT from Florida’s Cape Canaveral Space Force Station.
Several minutes into the flight, mission controllers reported the 110-foot rocket experienced an anomaly with its upper stage that prevented it from reaching orbit. The upper stage is designed to ignite separate engines midflight to boost the rocket into space.
The startup wanted to put the rocket – dubbed "Good Luck, Have Fun," or "GLHF" – into a 125-mile-high orbit for several days before having it plunge through the atmosphere and burn up along with the rocket's upper stage.
The first stage was accomplished after liftoff from Cape Canaveral and separated as planned. In the end, the upper stage appeared to ignite and then shut down.
Overall, "GLHF" was successful beyond what Relativity had initially hoped.
Third launch attempt for Relativity Spac
It was the third launch attempt from what once was a missile site. Relativity Space came within a half-second of blasting off earlier this month as the rocket’s engines ignited before abruptly shutting down.
An initial launch attempt March 8 was scrubbed "due to exceeding launch commit criteria limits for propellant thermal conditions on stage 2," the company said. Relativity Space's second launch attempt for the rocket on March 11 was halted for two automated aborts, the company said on Twitter.
What was the 3D-printed rocket's mission?
The goal of the launch was to prove the 7.5-foot-diameter 3D-printed vehicle is durable enough for launch and space flight.

Liftoff and getting over the Atlantic and passing Max-Q – the point in the flight when the rocket would be at maximum stress – would "be a big inflection point," the company said this month in a discussion of launch success on Twitter. "Why? Because it's the phase of flight where the structural loads on the vehicle are the highest, passing this point in flight proves our hypothesis: 3D printed rockets are structurally viable!"
The launch is just the first step in Relativity's plan to go to Mars.
Last year, the company announced plans with Impulse Space of El Segundo, California, to develop a Mars Cruise Vehicle and Mars Lander on a Terran R rocket no earlier than 2024.
