Questions, concerns, and requests to Mission Support: Based on our average water usage and the fact that we are a larger crew, we have calculated that the minimum water level of ~145 gallons (“31 inches” from the top of the lid) is likely to be reached on Sol 10. We would like a resupply of the 125 gallons of H2O, as offered at the beginning of our mission, as a safety net. Thank you!
