Launch of world's first 3D

The firm is also working toward making future models of Terran 1, up to 95 percent 3D-printed. Its next model, the Terran R, meanwhile, will have a larger payload capacity and will be reusable, unlike the expendable Terran 1.

Firstly though, Relativity Space will have to launch Terran 1. The private space firm aimed to reset for a second launch attempt on Wednesday, though it ultimately stood down "due to exceeding launch commit criteria limits" for the fuel temperatures on the rocket's second stage, the company wrote on Twitter.

"We are scrubbing launch operations for the day, thanks for playing," the company's launch director added during the launch attempt live stream.

Relativity Space will make another launch attempt next week

Shortly after the scrub, Relativity Space said during its live launch commentary that it aims to make another launch attempt again next week. "Our next launch attempt window is confirmed for this Saturday, March 11 from 13:00 – 16:00 ET," Relativity Space announced on Twitter.

In an interview with Space.com prior to the Wednesday launch attempt, company officials said reaching low Earth orbit (LEO) in its first attempt isn't guaranteed at all and it would be viewed as "a total home run." As such, the rocket won't carry any scientific payload.

Player ready? Yup. Our next launch attempt window is confirmed for this Saturday, March 11 from 13:00 – 16:00 ET. #GLHF pic.twitter.com/lBXCm9nNeG

"While we obviously had high hopes for sending our Terran 1 off today, we're going to continue to take a measured approach so we can ultimately see this rocket off to Max Q and beyond," Arwa Tizani Kelly, test and launch technical program manager for Relativity Space, explained during live launch commentary.
