Astronauta androide reparando nave orbital

A dramatic cinematic sci-fi concept art illustration of a [female android astronaut] kneeling on the exterior hull of a massive spacecraft in orbit above Earth, performing emergency maintenance with a handheld plasma welding torch held in both hands. She wears a sleek white-and-silver biomechanical body suit integrated with robotic joints, segmented armor plates, visible black cables, micro-panels, and subtle weathering; her long [silver-white] hair streams wildly backward in zero gravity. Her face is covered by a plain opaque square censor block in muted gray, centered over the head area. She is posed on one knee with the other leg bent, leaning toward a vertical wall of dark spacecraft hull panels. The torch emits an intense blue-white point of light and a spray of orange sparks against the metal. Legible industrial markings on the wall read "[HULL SECTOR 12-A MAINTENANCE ACCESS]". In the background, the curved blue limb of Earth features glowing city lights below, set against deep black star-filled space and the colossal cylindrical spaceship hull receding into perspective. High contrast, cold blue rim lighting, orange spark highlights, glossy metal reflections, hard-surface sci-fi design, shallow depth of field, dynamic diagonal composition.
