First 3D-printed rocket lifts off but fails to reach orbit

The world's first 3D-printed rocket launched successfully on Wednesday, marking a step forward for the California company behind the innovative spacecraft, though it failed to reach orbit.

Billed as less costly to produce and fly, the unmanned Terran 1 rocket launched from Cape Canaveral, Florida at 11:25 pm (0325 GMT Thursday) but suffered an "anomaly" during second-stage separation as it streamed towards low Earth orbit, according to a livestream broadcast by aerospace startup Relativity Space.

The company did not immediately give further details.

While it failed to reach orbit, Wednesday's launch proved that the rocket -- whose mass is 85 percent 3D-printed -- could withstand the rigors of lift-off.

The successful launch came on the third attempt. It had originally been scheduled to launch on March 8 but was postponed at the last minute because of propellant temperature issues.

A second attempt on March 11 was scrubbed due to fuel pressure problems.

Had Terran 1 reached low Earth orbit, it would have been the first privately funded vehicle using methane fuel to do so on its first try, according to Relativity.

Terran 1 was not carrying a payload for its first flight, but the rocket will eventually be capable of putting up to 2,755 pounds (1,250 kilograms) into low Earth orbit.

The rocket is 110 feet (33.5 meters) tall with a diameter of 7.5 feet (2.2 meters).

Eighty-five percent of its mass is 3D-printed with metal alloys, including the nine Aeon 1 engines used in its first stage and the one Aeon Vacuum engine employed in the second.

It is the largest ever 3D-printed object and was made using the world's largest 3D metal printers, according to the Long Beach-based company.
