The fact that the International Space Station adjusts its solar arrays using rotational joints to track the Sun is a matter of direct, everyday observation and common technical knowledge, requiring no citation.
The claim is a straightforward, factual description of the International Space Station's hardware design (specifically its solar alpha rotary joints) used for power generation, which is common knowledge in aerospace engineering and everyday observation of spacecraft operations. None of the retrieved papers specifically address or evaluate this exact mechanism as a primary thesis, as they cover unrelated topics like microbial tracking, Earth-observation satellites, and space robotics.
