NASA will host a media teleconference at 12 p.m. EST Thursday, Dec. 10, to discuss the next test in the Green Run testing series for the Space Launch System (SLS) rockets core stage that will fly on the agencys Artemis I mission. Thetest, known as the wet dress rehearsal, will begin Saturday, Dec. 5, and take place over several days at NASAs Stennis Space Center near Bay St. Louis, Mississippi. Engineers will power up all the core stage systems and load and drain more than 700,000 gallons of cryogenic, or supercold, propellant into the tanks for the first time.
TheGreen Runtest series is a comprehensive assessment of the rockets core stage prior to it launching Artemis missions to the Moon. NASA has completed six of theeight core stage Green Run testsand is in the final stage of testing, which will operate the entire stage and its propulsion systems together for the first time.Following the completion of the wet dress rehearsal, NASA will set a date for the hot fire test. During the hot fire test, all four engines will fire to simulate the stages operation during launch.
