NASA plans to test-fire the core stage of its Space Launch System on Saturday around 5 p.m. EST.




The core stage will burn through more than 700,000 gallons of liquid propellant over eight minutes while strapped to a test stand at NASA's Stennis Space Center in Mississippi.




NASA TV plans to broadcast live coverage of the firing — the final test in the agency's "Green Run" series — starting at 4:20 p.m. EST.




The test is a crucial step toward a the first launch of SLS, which is currently scheduled for November 2021.

NASA plans to fire up the world's most powerful rocket stage on Saturday in a vital test for its forthcoming mega-size moon rocket, and you can watch live video of the action below.The final rocket, called Space Launch System, is designed to eventually stand 365 feet (111 meters) and ferry astronauts to the moon sometime in the mid- to late-2020s. The system is an essential piece of a larger program called Artemis, a roughly $30 billion effort to put boots back on the lunar surface for the first time since 1972.NASA expects to hot-fire the 212-foot (65-meter) core stage of SLS - the system's largest piece and its structural backbone - on Saturday at 5 p.m. EST at Stennis Space Center in Bay St. Louis, Mississippi. Boeing is the core stage's lead contractor, and Aerojet Rocketdyne is responsible for its four powerful RS-25 engines, which used to power NASA's fleet of space shuttles.The core stage's firing is the eighth and final test in NASA's "Green Run," a testing series designed to put each part of the core stage through a rigorous validation ahead of SLS's first launch, called Artemis 1 - an uncrewed test flight currently scheduled for November 2021.
