NASA has resolved troubling airflow vibrations detected during Artemis I. By combining wind-tunnel tests, advanced pressure-sensing paint, and supercomputer simulations, engineers added aerodynamic strakes to the SLS rocket. The fix cuts turbulence, ensuring Artemis II remains safe and on schedule for its upcoming crewed mission to the Moon.NASA has resolved troubling airflow vibrations detected during Artemis I.
