NASA’s Tech Arsenal Powers Artemis II Mission

Speedy Summary

• NASA is using advanced computational capabilities and wind tunnel experiments to improve the Space Launch System (SLS) rocket for the Artemis II mission, which will be the first crewed lunar journey of the Orion spacecraft on a 10-day mission around the moon.
• During Artemis I, unsteady airflow caused higher-than-expected vibrations near solid rocket booster attach points. Engineers proposed adding four “strakes” – fin-like structures – to minimize these vibrations.
• The strake design was refined using experiments in NASA’s Unitary Plan Wind Tunnel with an innovative Unsteady Pressure Sensitive Paint (uPSP) technique capturing rapid pressure changes. Data was analyzed on NASA’s hyperwall visualization system via a high-speed network connection between facilities.
• The Cabeus supercomputer facilitated complex simulations to model airflow dynamics, complementing wind tunnel data where sensors could not reach. This sped up data processing timelines from weeks to hours.
• A collaboration involving multiple teams led by NASA’s Advanced Supercomputing Division contributed to safe and efficient designs by enabling real-time adjustments based on visualization feedback.
• Construction of the strake-equipped SLS rocket at Kennedy Space Center is expected to finish by October 2025.
