Little SLS launches in low speed wind tunnel

In the 14- by 22- Foot Subsonic Tunnel, researchers were able to measure the influence of ground winds on structures at the launch pad that might impact the SLS rocket.

Prior wind tunnel tests were simplified, but this new testing campaign featured 1.75% scale models of two SLS configurations, Block 1 Cargo and Block 1 Crew, along with the fully 3D-printed 1.75% scale launch tower model.

This data is needed to refine the rocket's guidance and control systems. Engineers are measuring the forces and loads that air induces on the launch vehicle during every phase of its mission.

SLS will be the most powerful rocket NASA has ever built, enabling astronauts to return to the lunar surface with the Artemis program.

SLS is the rocket that will send astronauts to the Moon, Mars, and beyond as NASA continues exploring our universe.
