Astronaut spacewalk beside space shuttle above blue Earth

A breathtaking, photorealistic scene of a NASA astronaut performing an extravehicular activity (EVA) from the Space Shuttle in low Earth orbit. The astronaut is wearing the iconic white Extravehicular Mobility Unit (EMU) spacesuit with a reflective gold visor, floating just outside the Shuttle's open payload bay while secured by a safety tether. The Space Shuttle's distinctive black-and-white thermal protection tiles, payload bay doors, robotic arm, and orbital maneuvering system pods are clearly visible. Below, the curved blue Earth fills the background with swirling white clouds, deep blue oceans, and the thin glowing atmosphere along the horizon. Brilliant sunlight creates dramatic highlights on the spacesuit and Shuttle, with deep shadows contrasting against the blackness of space. The image conveys the immense scale, isolation, and wonder of human spaceflight. Ultra-detailed, cinematic composition, realistic lighting, crisp textures, NASA-inspired accuracy, high resolution, and a sense of awe and exploration.
