Mission Journal: Patch #2.8.3.2159 Date of entry: 2148/01/21 Habitat 6 experienced a minor water recycling glitch this morning; sensors indicated impurities above safe thresholds. Thankfully, engineering identified a clogged filter—likely sediment buildup from minerals in Martian soil. They promptly replaced the filter cartridge and reset the system. Now running smoothly again.
