Relativity Space sets launch of world's 1st 3D-printed rocket for March 8

The world's first 3D-printed rocket may soar to space as soon as March.

Relativity Space says it has launch licenses ready for its expendable, 3D-printed Terran 1 rocket to attempt its orbital debut on March 8, no earlier than 1 p.m. EST (1800 GMT).

Company officials confirmed on Twitter Wednesday (Feb. 22) that the launch will proceed from Cape Canaveral Space Force Station on Florida's space coast. The mission is called GLHF (Good Luck, Have Fun) and will assure the readiness of the 110-foot (33-meter) Terran 1 before it flies customer payloads.

The company's rocket, about 85% 3D-printed by mass, has been called "the largest 3D printed object to exist and to attempt orbital flight" by the company. Relativity Space plans to boost 3D-printing on Terran 1 rockets to 95% of its mass.

Additive manufacturing is also used for the nine Aeon engines on the first stage of the rocket, and the Aeon Vac engine on the second. In a nod to environmental sustainability, Relativity Space also will use liquid oxygen as well as liquid natural gas for Terran 1. If the rocket makes it to space, it will be the first to do so with natural gas fuel and will form a keystone of Relativity's eventual plan to use methane on Mars for its planned Red Planet missions.

Relativity was co-founded by Tim Ellis and Jordan Noone in 2015 following work at Blue Origin and SpaceX, respectively. The small-lift rocket can send up to 2,756 pounds (1,250 kilograms) to low-Earth orbit, according to Relativity, and a bigger booster is in production.

Relativity unveiled Terran R in 2021, a much larger booster of 216 feet (66 m) tall by 16 feet (4.9 m) wide that can send nearly 25 times the payload mass of Terran 1 into space. The fully reusable rocket, launching as soon as 2024, can send as much as 44,100 lbs. (20,000 kg) to low Earth orbit.

Terran R's capacity is approaching that of SpaceX's Falcon 9, a competitor that regularly sends large payloads for NASA, the security industry and its own satellite constellation (Starlink) to space for almost 10 years. Falcon 9 is also partially reusable as the first stage can be returned on land or to a drone ship.
