A set of large RS‑25 rocket engines sit inside a bright industrial processing facility at NASA’s Kennedy Space Center. Two engines on the left are wrapped in protective plastic and secured on yellow transport stands, while an unwrapped engine on the right shows detailed plumbing, wiring, and the wide nozzle opening. Overhead cranes, metal platforms, and safety railings surround the workspace, and a technician stands in the background near the wall.图:NASA · NASA Image and Media Guidelines
