Thrilling news of the day: The mechanical workshop have printed me a set of scale models of the Cluster spacecraft. They're for my interactive in the Aurora Explorer exhibit at the Royal Society Summer Exhibition. They were done on the rapid prototyper, a 3D printer that builds up pieces from thin layers of plastic. My baby spacecraft were assembled from five printed sections, as shown below.
