[ SPACE ]

This facility is an incubator that can maintain constant temperature, humidity, and carbon dioxide levels. It was launched aboard the Space Shuttle in 2008 and installed in the Kibo module on the International Space Station (ISS). It is used for various space experiments, including cell culture experiments and small animal research. The facility consists of a Microgravity section for conducting experiments in microgravity and a 1G section that provides artificial gravity to subjects through centrifugal force, enabling comparative experiments.
