Today's #AstroFriday question is about observing changes in water over time from the vantage point of space.
Project WET: What changes over time, if any, will you be looking for in water features on Earth during your time on the International Space Station?
Ricky Arnold: Our water resources on Earth will continue to be affected by climate change. I hope to be able to share some of the changes we have observed since the space station began flying seventeen years ago.
