Questions, concerns and requests to Mission Support:

1) We were wondering if the water consumption sheet was functioning well. The sheet says that we used 3.8 gallons of water today, but after our calculations it should be a lot more (8L for dishes, at least 2L for hygiene, 10L at least for drinking so it should be at least 5 gallons…) I know that the sheet is not precise especially in the first few inches because of the geometry of the water tank, but isn’t this difference too big?

2) About yesterday’s question: what is an UPS? Is there a particular charging port that we should use in the science dome in order to not lose power during the power source switch? Could you explain more about how we could fix this problem? Thank you!
