Cape Canaveral, Florida - The world's first 3D space rocket lifted off from Cape Canaveral in Florida on Wednesday.

The unmanned Terran 1 lifted off at 11:25 PM EDT after two postponements due to propellant temperature issues and fuel pressure problems.

Terran 1 – a two-stage, 110-foot tall and 7.5-foot wide rocket – is "the largest 3D printed object to exist and to attempt orbital flight," according to Relativity Space, the California aerospace startup that built it.

The rocket is currently 85% 3D printed by mass, including its engines, though Relativity Space is aiming to raise that number to 95%.

In its maiden flight, the rocket, which is a prototype vehicle that does not include a customer payload, was set to reach orbit after eight minutes.

Had the rocket actually reached orbit, Relativity Space would have been the first privately-held, venture-backed space company to have successfully done so on its first launch.

However, an anomaly about five minutes into the flight meant the mission did not reach orbit. Terran 1 did reach Max-Q, the point in the launch sequence where the rocket experiences the maximum dynamic pressure.

"Today’s launch proved Relativity’s 3D-printed rocket technologies that will enable our next vehicle, Terran R," the company said after the launch, calling it "a huge win, with many historic firsts."

Terran 1 is designed to carry up to 1.3 tons into low Earth orbit.
