By the 12th second, the vertical column began to collapse, while massive water surges co

Marshall Space Flight Center on Instagram: "Smooth ride ahead! 🚀 NASA engineers used cutting-edge supercomputers and wind tunnel testing to improve the SLS (Space Launch System) rocket for Artemis II, the first crewed Artemis mission around the Moon. Supercomputers and wind tunnels converge at NASA's Ames Research Center—explore how this state-of-the-art capability delivers smarter, more cost-effective science. “This new technique lets us see wind tunnel data in much finer detail than ever befo
