Most people associate NASA with exploring the vastness of space, but much of NASA’s research is directly related to water – both on and off our Blue Planet. The Water Brothers visit a NASA research centre to better understand how water is an essential component of every rocket launch and test out the water recovery system used on the International Space Station. Through interviews with astronaut Chris Hadfield, astrophysicist Neil deGrasse Tyson and numerous renowned NASA scientists and engineers, the Water Brothers learn how space technology is advancing our understanding of water, both here on Earth and throughout the universe.
