Known for their disdain of scrubs, the R&B group TLC is surely disappointed after Wednesday’s scheduled launch of the world’s first 3D-printed rocket was called off by Relativity Space.

The Long Beach-based firm’s first Terran 1 rocket was slated to blast off from Launch Complex 16 at Cape Canaveral at 10 a.m. PST Wednesday. After multiple holds, including a last-minute one at T-70 seconds, and a recycle attempt that pushed liftoff to 12:55 p.m., the company announced the launch was scrubbed due to an issue with the methane-liquid natural gas fuel temperature in the rocket’s second stage.

The company will attempt the launch again on Saturday at 10 a.m. PST.

“While we obviously had high hopes of sending our Terran 1 off today, we’re going to continue to take a measured approach so we can ultimately see this rocket off max-q and beyond,” Arwa Tizani Kelly, technical program manager for Relativity, said during a livestream.

Dubbed “Good Luck, Have Fun,” the mission was not carrying a customer payload. Instead, the nose cone contained a single artifact: a 3-pound, 6.5-inch-diameter metal disc, which was the first item created using the first generation of the company’s Stargate printer, the largest 3D metal printer in the world.

The rocket is 85% 3D-printed, making it the largest 3D-printed object to exist, according to the company. Future iterations of the Terran 1 are expected to be 95% 3D-printed.

“It will take a few days until our next attempt,” Relativity founder Tim Ellis tweeted. “Onward, and proud of the team today for a professional and smooth first operation!”
