On March 18, 2021, the core stage for the first flight of NASA’s SLS (Space Launch System) rocket underwent a hot fire test on the B-2 Test Stand at NASA Stennis. The four RS-25 engines fired for the full duration of 8 minutes during the test and generated 1.6 million pounds of thrust while consuming more than 700,000 gallons of liquid oxygen and liquid hydrogen propellants. The hot fire test was the final stage of the Green Run test series, a comprehensive assessment of the SLS core stage prior

Simulation of the SLS rocket system using NASA’s Launch Ascent and Vehicle Aerodynamics (LAVA) software.This video shows a simulation of the SLS (Space Launch System) rocket using NASA’s Launch Ascent and Vehicle Aerodynamics solver. For the Artemis II test flight, a pair of six-foot-long strakes were added to the core stage of SLS that will smooth vibrations induced by airflow during ascent. The green and yellow colors on the rocket’s surface show how the airflow scrapes against the rocket’s sk
