The authors are grateful to JamesDodge and his colleagues at NASA, who conceived the WetNet Project, made it an overwhelming success, brought together researchers throughout the world, and ultimately provided us with the opportunity to contribute to this special issue. The lead author (RF) also acknowledges Eric Smith for his dedicated effort in PIP-2 and encouraging the collaborative effort on the common screen. RF also thanks all the co-authors for their contributions to the manuscript; it was truly a “team effort”! Finally, RF also wants to express sincere gratitude to Norm Grody, who is truly the “expert” in this area of research and has taught me most of what I know in this field.
