SAN FRANCISCO, Nov. 16 (Xinhua) -- Boeing announced that NASA's Space Launch System rocket, powered by the Boeing-built core stage, lifted off at 1:47 a.m. ET on Wednesday from the Kennedy Space Center.
Eight and a half minutes into flight, the core stage completed its mission and separated from the upper stage of the rocket, sending NASA's Orion spacecraft on its first journey around the moon, the company said.
"Today, this country now has a super-heavy lift launch capability for the first time in 50 years," said Jim Chilton, senior vice president of Boeing's Space and Launch division. "This test flight was a demonstration of engineering innovation, and we are ready to support NASA and their international partners in returning humans to deep space exploration."
During the mission, the core stage demonstrated several important functions, including fueling both tanks, actuating the hydraulic system, igniting the engines, running thrust vector control programs in flight, depleting the fuel tanks, shutting down the engines, and conducting successful separation and disposal maneuvers.
The core stage of the rocket stands at 212 feet (almost 65 meters), and is comprised of a 196,000-gallon liquid oxygen, a 537,000-gallon liquid hydrogen tank, along with an intertank section joining the two fuel reservoirs, a forward skirt on top that connects to the upper stage, and an engine section with four RS-25 engines combining for 2.2 million pounds of thrust, according to the announcement.
A Boeing team manufactures the core stage at NASA's Michoud Assembly Facility in New Orleans, Louisiana, and uses components made by more than 430 suppliers across the United States.
