Unknown fungus-like lifeforms have hitched a ride on one of the shuttles and infected the docking bay during a routine hull check. While we believe we have contained the contamination to the bay and are now using the emergency docking bay for any physical transportation on and off the ship.
On our explorations of Sector 356 we have also encountered a previously unknown caterpillaris species. Two red stripes run along its entire spine enclosing morse-like dots and dashes. At present it covers the entire aft of the USS Signature. Though they do not seem to be damaging the hull we are continuing observations as a precaution.
A replacement pipe has been found and astroculture production have restarted after routine maintenance was completed.
