LOS ANGELES, April 17 (Xinhua) -- SpaceX scrubbed the launch of its powerful Starship rocket on Monday morning due to technical issues.

The launch, which marks the first flight test of SpaceX's fully integrated Starship and Super Heavy rocket, was scheduled at 8:00 a.m. Central Time from SpaceX' Starbase in U.S. state of Texas.

A pressurant valve appeared to be frozen before the launch, according to Elon Musk, founder, CEO and chief engineer of SpaceX.

Later, SpaceX confirmed standing down from Monday's flight test attempt, saying the team is working towards next available opportunity.

"Learned a lot today, now offloading propellant, retrying in a few days," Musk tweeted.

The launch came after the U.S. Federal Aviation Administration on Friday approved SpaceX's launch of the nearly 120-meter-tall rocket from its Boca Chica Launch Site in Cameron County, Texas.

SpaceX's Starship spacecraft and Super Heavy rocket, collectively referred to as Starship, represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond.

Starship will be the world's most powerful launch vehicle ever developed, capable of carrying up to 150 metric tonnes fully reusable and 250 metric tonnes, according to SpaceX.
