Satellite radiators are typically huge and heavy — not at all ideal for tiny spacefarers like CubeSats. To address small satellites need, NASA Goddard technologist Vivek Dwivedi has teamed up with Brigham Young University scientists to develop a smart radiator inspired by origami. The three-dimensional structure made out of temperature-sensitive materials like shape-memory alloys can fold and unfold to preserve and shed heat, respectively. It also folds when it wants to soak up he…Read more
