As our goal is to design a system to keep the crew supplied with water in deep space, our first step is to analyze the amount of water needed for the crew of 150 for one day. Taking personal hygiene, cooking, drinking, and others, we have determined the following: Activity Daily Consumption of Water per Person (Gallons) Shower 20 Laundry 2 Toilets 5 Faucets 5 Dishwasher 7 Drinking 1 Cooking 2 Total 42 We can safely estimate that the average person’s water consumption for one day is 42 gallons. 1 Using the SI system of measures ( )*( . ) 42 Gallons1 Day 3 785 Liters1 Gallon = . 158 97 Liters1 Day * 160 Liters1 Day 1 Person Since the astronauts in space do not have an endless supply of water, the logical choice is to recycle water. Given that the water will be recycled continuously, we will need enough water to maintain storage of * 160 Liters1 Day 1 Person * ( ) 150 persons * (1 Day) = 24000 Liters This is the amount that the 150 astronauts will use per day. With the latest current water- recycling technology, it is possible to recycle around 90 percent of the water used. 2 At this rate,
