Lean Mean SLS Machine - A 5-percent scale model of the Space Launch System (SLS) is ignited for five seconds to measure the effects acoustic noise and pressure have on the vehicle at liftoff. The green flame is a result of the ignition fluid that is burned along with the propellant during this short-duration test. The tests will allow engineers to verify the design of the sound suppression system being developed for the agency's new deep space rocket.
The first flight test of the SLS in 2017 will be configured for a 70-metric-ton (77-ton) lift capacity and carry an uncrewed Orion spacecraft beyond low-Earth orbit to test the performance of the integrated system. As the SLS is evolved, it will the most powerful rocket ever built and provide an unprecedented lift capability of 130 metric tons (143 tons) to enable missions even farther into our solar system.
