A cinematic scifi-film scene showing a botanist and a small maintenance drone tending plants inside a vast hydroponic dome aboard an orbiting space station. The botanist is a calm man in his fifties with a neatly trimmed white beard and round wire glasses, wearing a pale green jumpsuit with rolled-up sleeves and a tablet clipped to his belt, gently holding a glowing blue leaf between his fingers as he inspects it closely, then nodding toward the drone hovering at his shoulder. The drone is a compact white sphere with four soft-lit rotor pods and a thin articulated arm, spraying a fine shimmering mist over the leaf he holds, its small lens tilting toward him as if waiting for approval. Around them rows of terraced plant beds spiral upward under curved glass, strange bioluminescent ferns and heavy fruit vines fill every level, Earth hangs huge and blue beyond the dome, soft white grow lights mix with the cool planet glow, droplets sparkle in the air, a peaceful and hopeful atmosphere.
