Which module features a dedicated cargo airlock for moving scientific payloads externally?
Answer
Mengtian
The Mengtian module, identified as the second laboratory module, is equipped with a specialized cargo airlock. This feature is distinct from the crew EVA airlock found on the Wentian module. The purpose of the Mengtian cargo airlock is specifically to facilitate the transfer of scientific payloads, such as external experiment mounting hardware or samples, from the pressurized interior environment of the station out to external mounting platforms situated outside the spacecraft, maximizing the station's in-orbit research capabilities.
