Questions, concerns and requests to Mission Support: Request for flour and olive oil, as the supplies received included an already opened bag of flour and an opened container of olive oil with about 50% remaining.
We would also like to request microfiber towels or dish towels. The crew reports difficulty effectively removing food residue prior to washing, resulting in increased water usage. Kitchen towels were listed among the supplied items but are not currently present in the Hab. Providing reusable towels would support water conservation efforts and help ensure sufficient supply for the duration of the mission.
Could you please advise on availability or assist in locating or supplying these items?
Additionally, per David’s instructions, I am requesting clarification regarding the toilet tank emptying procedure. The current process appears to require a continuous flow of water followed by a flush, which may use a nontrivial volume of water. Could Mission Support please confirm the approximate water usage for this procedure?
If possible, we would also like to request a written exception or guidance on whether water conservation measures may be applied, such as reducing the duration the valve remains open or minimizing water used during the flush, while still maintaining proper system function. Any recommendations for safely reducing water usage during this process would be appreciated. Otherwise, we will continue to follow the procedure as currently written.
