The world's first 3D-printed rocket launch plan was canceled at the last minute.
The Terran 1 rocket, installed on the launch pad of Cake Canaveral, Florida, began a three-hour countdown from 1 p.m. on the same day, but had to stop launching due to pressure problems with the second-stage propellant, according to the U.S. startup "Larity Space."
Initially, Relativity Space was scheduled to launch the Terran 1 rocket on the 8th, but it also failed at the last minute due to the temperature of the propellant.
Reliability Space said it would reschedule the launch soon and try again.
The rocket is 33.5 meters high and 2.2 meters in diameter, and 85% of its mass, including the engine, is 3D printed with metal alloys.
After launch, the goal is to enter the low-Earth orbit (LEO), and if successful, most of them will be made with 3D printing technology and recorded as the first civilian rocket to use methane (methane) fuel.
Founded in 2016, Relativity Space aims to manufacture rockets with 95% of the body printed in 3D. Through this, the number of parts can be reduced to one-hundredth of that of existing rockets and the rocket can be manufactured in 60 days.
Reliability Space plans to launch a mid-sized recycling rocket called Terran R from Cape Canaveral next year, which is larger than Terran 1.
Lalertity explained that after the countdown, pressure problems were confirmed in the second stage of the propellant, so the launch was stopped. The launch schedule will be rescheduled soon.
After launching the rocket, Lalertity aims to enter low-Earth orbit. If the launch is successful, it will be listed as the first civilian rocket built with 3D printing technology and using methane fuel.
To simplify the rocket production process, Lalertity will continue to reduce costs by using huge 3D printers.
Josh Brost, senior vice president of Relativity, told Reuters that the "Teran 1 rocket is the largest 3D printing structure ever assembled."
