problems encountered on previous flights were not present.  The crew religiously changed urine cup filters at the first sight of urine drops "pooling" in the cup.  It is recommended that a sufficient number of urine cup filters be flown to allow changeout 2 or 3 times daily (R).  Feces collection was nominal until flight Day 5 when the crew had to resort to the old trick of "pushing it aside."  While this is a workable solution, it is not a desirable solution, and the WCS is not considered fully operational until a method is devised to relieve the crew of this task (R).  The Personal Hygiene Station (PHS) was evaluated by the crewmembers and it was determined that it offered no advantages or improvements over traditional hygiene methods.  It is recommended that the PHS be removed from the Orbiter (R).  However, the sudsless soap flown with the PHS should be retained as a crew option (R).

Orbiter Atmosphere:  The crew routinely inspected and cleaned cabin, IMU, and (with more difficulty) DEU filters.  Also, a lot of lint was collected (by hand) from the filter behind the seat in the WCS.  According to the experienced crewmembers, the cabin air on 41-G was much cleaner than on previous flights; and as in previous flights, it is recommended that all filters be easily accessible for cleaning (R).

Galley/Food Preparation: The galley worked well for the entire flight and is considered a near must for a crew of this size.  The galley is sized perfectly for the preparation of seven meals simultaneously.  Meal preparation for a large crew without the galley would require nearly 30 more minutes and an additional food warmer.  All minor galley problems were associated with the doors:  (1) the top doors need to be removed, halved, or trimmed at the bottom to allow the lowerdoor to operate independently (R); (2) the lower door needs a more positive "lock-up"/"lock-down" mechanism (R); and, (3) a design is needed for a more positive method of attaching the food trays (be it magnets or velcro) to the galley doors (or the galley if doors are removed) (R).  It was the crew's perception that bubbles in the drinking water increased in a direct proportion to the length of the flight and that toward the end of the flight the galley was "laboring" to fill the drink containers.  There was a procedural error in the middle of the flight that closed the galley water supply for a period of time, which may or may not have contributed to the "bubble" problem.  

Sleep Stations:  As always, sleeping habits are individual and varied.  After the normal 1-2 day "try out" period, the crew settled on the following arrangement:  CDR in his seat, PLT in the airlock between EMU-1 and EMU-2, MS1 on the aft flight deck, MS2 in the PLT's seat, MS3 in a sleeping bag on the middeck starboard bulkhead, PS1 floated free on the middeck in an Apollo bag, and PS2 was under MS3 on the middeck starboard bulkhead (in a sleep restraint).

Stowage:  Stowage was adequate and, for the most part, well designed with no significant problems.  Volume G popped open during ascent and stayed open through landing.  Volume H (EVA volume) was difficult to open initially.  All lockers were fastened for entry and landing.  The PLT clothing locker was outfitted with new design fasteners which worked well enough to be considered for all lockers (R).

Trash Management:  Trash management for a crew of seven must be a conscientious effort in maximizing trash density.  Only wet trash (food containers, WCS related material) was placed in the wet trash compartment, which reached its capacity by mission end.  Drink containers for the entire mission were collected, compressed, and stowed in a large jettison bag (in the airlock on orbit; on the
