The document discusses water usage and conservation on the International Space Station. It notes that water must be transported from Earth at a cost of $10,000 per pound since it cannot be produced on the ISS. Various daily activities like showering, brushing teeth, and flushing toilets use significant amounts of water. As a result, NASA has implemented strict conservation measures and reprocesses wastewater through systems that mimic natural water filtration on Earth. Recycling existing water is crucial since transporting enough water for a 4-person crew for a year would cost $400,000.
3. In space, what do water and air have in common?
4. They don’t exist. If you want them, you have to take them with you when you launch from earth.
5. The water is brought from earth or is produced as a by-product of fuel cells on the orbiter. The Shuttle Transportation System (STS)
6.
7. 1/8 gallon Glass of water 3 gallons Brushing teeth, 2 mins, water on 2 gallons Washing hands/face 3 gallons every flush Flushing a toilet 36 gallons Taking a shower, 20 mins. 50 gallons Taking a bath USE ACTIVITY
8. How much do you estimate that you use in one day? How much do you use daily? How much would in 4 months? (laundry, gardening, too) What would be the cost to LAUNCH the water you need for four months?
20. VCD BENEFITS Process about 4,400 lbs of water annually for ISS Human exploration beyond the moon requires such recycling systems Implications for Earth – 6.2 billion+ (abundant, reliable, affordable sources of water)
Welcome to the session of The International Space Station Conference – on the screen you can see flags of each of the countries who serve as partners in this exciting space venture.
Let’s make sure that you’re in the session you want to be in right now. This is “Every Drop Counts” and I’ll be sharing with you some exciting information about water and the International Space Station.
