The sun sets behind NASA’s Space Launch System (SLS) rocket and Orion spacecraft as they stand fully assembled atop the mobile launcher at Launch Pad 39B at NASA’s Kennedy Space Center in Florida. The sky glows with warm shades of orange and pink, silhouetting the towering rocket and its solid rocket boosters against the fading light. Photographed on January 31, 2026, the scene captures teams preparing for a wet dress rehearsal for the Artemis II mission, rehearsing launch countdown timelines and procedures as day turns to night.
