The tea storage on the International Space Station (ISS) is designed to keep the tea fresh and prevent it from spilling in the microgravity environment. Tea bags are stored in special containers that are sealed with airtight lids to prevent moisture and air from affecting the quality of the tea. These containers are also designed to be compact and take up minimal space on the ISS. Once the tea bags are used, they are disposed of in the ISS's trash compactor, which compresses the waste and stores it until it can be disposed of during a cargo resupply mission. Overall, the tea storage on the ISS is designed to meet the particular challenges of space travel, such as the need to prevent loose items from floating away in microgravity and the limited storage space available.
