Question

question 19
why is it important that they reclaim water as efficiently as possible mimicking the
water cycle while in space?
reclaiming water helps astronauts to understand if they are having health issues while in
space.
water can be pulled out of space but the machine to do it is very loud so it is easier to recycle
pee instead.
water is lighter when it is reprocessed so it makes sense to recycle.
reclaiming water is a life support system needed to have extended stays in space.
question 20
an astronaut was quoted as saying “...today’s coffee is tomorrow’s coffee!” what is
meant by that saying?
coffee that was made today will be reheated for tomorrow’s coffee.
the coffee from today will become urine, then collected, filtered and sanitized to make fresh
water for tomorrow’s coffee.
the same kind of coffee is being made each day.
coffee isn’t made in space, but instead premade and served tomorrow.

Explanation:

Question 19: Space missions have limited water storage; efficient water reclamation (mimicking Earth’s water cycle) ensures a sustainable life support system for long-duration stays, as resupplying water from Earth is impractical.
Question 20: The quote refers to closed-loop water recycling in space: liquid waste (like urine from consumed coffee) is processed, purified, and reused to create fresh water for future needs, including making coffee.

Answer:

Question 19: D. Reclaiming water is a life support system needed to have extended stays in space.
Question 20: B. The coffee from today will become urine, then collected, filtered and sanitized to make fresh water for tomorrow's coffee.
