This week's #AstroFriday question is about how Ricky's time in space has affected his views about water on Earth.
Project WET: Based on your experiences in space now and on your first mission, have you changed how you use water, or do you plan to when you return to Earth?
Astronaut Ricky Arnold: My attitudes about where water comes from have certainly changed, and that is something I'll continue to share when I get back. With so many communities around the world suffering from a lack of potable water, we'll all need to continue to work to overcome our understandable bias against water from sources such as urine-processing.
